This supplemental file contains information regarding the data extraction and quality evaluation results for data sources
that were considered for the Supplement to Draft Risk Evaluation for Asbestos Part 2: Supplemental Evaluation Including
Legacy Uses and Associated Disposals of Asbestos and that underwent systematic review. The systematic review steps are
further described in Supplement to the Draft Risk Evaluation for Asbestos Part 2: Supplemental Evaluation Including Legacy
Uses and Associated Disposals of Asbestos. EPA conducted data extraction, and quality evaluation based on author-reported
descriptions and results; additional analyses (e.g., statistical analyses) potentially conducted by EPA are not contained in this
supplemental file. EPA used the TSCA systematic review process described in the Draft Systematic Review Protocol Supporting
TSCA Risk Evaluations for Chemical Substances (also referred to as the '2021 Draft Systematic Review Protocol').
Data that met the RESO screening criteria during the full-text screening was extracted by three data types, general facility,
occupational exposure, and environmental release, as explained in Section 6.2 of the 2021 draft systematic review protocol.
Five different data quality evaluation forms were used depending on the data type and condition of use (COU), as explained
in Appendix M of the 2021 draft systematic review protocol. All references with data points containing monitoring data (e.g.,
measured occupational exposures) underwent data quality evaluation as described in Section M.6.1, using the monitoring data
quality metrics. All references with data points containing environmental release data (e.g., measured or calculated quantities
of chemical release across facility fence line) underwent data quality evaluation as described in Section M.6.2, using the
environmental release data quality metrics. All references with data points containing published models for environmental
release or occupational exposure (e.g., published models used to calculate occupational exposure or environmental releases)
underwent data quality evaluation as described in Section M.6.3, using the published models for environmental release or
occupational exposure quality metrics. All references with data points containing completed exposure or risk assessments (e.g.,
completed exposure or risk assessments containing a broad range of data types) underwent data quality evaluation as described
in Section M.6.4, using the completed exposure or risk assessments quality metrics. All references with data points containing
reports for data or information other than exposure or release data (e.g., process description) underwent data quality evaluation
as described in Section M.6.5, using the reports for data or information other than exposure or release data quality metrics. The
extracted data and their data quality evaluation are available in the tables below.
Additionally, each data type and condition of use is evaluated independently within a given study; therefore, each reference
may have more than one overall quality determination (OQD) to reflect the quality of each outcome and the exposures and
releases more appropriately as described by the study authors. No OQD is determined for each reference, as a whole, if it
contains data from more than one evidence stream.

Area sampling data: "Air samples were collected during and after asbestos abatement activities and demolition of the building. A total of 9 air samples were collected at the perimeter
of the site during asbestos abatement. The concentration of asbestos in one sample was reported by the laboratory as less than 0.03 f/cc, but all others were 0.01
f/cc or less. A total of 15 air samples were taken during asbestos abatement right at the work areas. The highest concentration of asbestos at these locations was
one sample that showed 0.05 f/cc asbestos in air; the other sample results were 0.01 f/cc or lower. Finally 18 air samples were also collected in areas of the
building where abatement was complete to verify that asbestos did not remain in ambient air. Three of these samples were above 0.01 f/cc, including one sample
at 0.21 f/cc. The remainder of the samples were all below 0.01 f/cc. The three samples above 0.01 f/cc were believed to be associated with removal of exterior
asbestos-containing siding very near the interior sample collection point.Corresponding background air samples at the site perimeter that day showed asbestos
levels of 0.004 f/cc or less, indicating that the exterior siding removal may have created localized elevations of asbestos concentrations, but did not contribute to
significant levels of asbestos migrating off site" (pg 5)

EPA's contractor (OHM Remediation Services Corp.) proposed a method that provided for the demolition of the structures ona section by section basis utilizing:
1) selective cutting and removal of key structural elements (piping systems, beams, etc.) during the pre-demolition phase, 2) controlled and predictable dismantling
of consecutive 16 ft. x 28 ft. wall and roof sections, and 3) managing debris piles until disposal. The plan specified the need for constant dust control using water
suppression (misting) during the demolition phase and either water suppression or tarping of asbestos wastes until it could be removed from thesite (5). [PDF Pg.
2]
Inhalation
Dust (solid) [PDF Pg. 2]
Between September, 1996 and June, 1997 a total of 1324 air samples were collected at the site in support of the removal action (10). Asbestos fiber concentrations
in ambient air collected at perimeter air monitoring stations were in the range 0.001 to 0.008 fibers/cc with the average concentration close to the detection limit
of 0.001 fibers/cc. [PDF Pg. 4]
Samples were analyzed by Phase Contrast Microscopy (PCM) in accordance with approved OSHA or NIOSH analytical procedures, with additional analysis

Area sampling data: Area Asbestos (NIOSH Method 7400) - Area asbestos sampling was conducted at four of the five facilities. Sampling pumps were placed in areas near asbestos
containing materials that employees would potentially encounter during a work shift (e.g., removed turbine shells, piping containing asbestos, or in areas with
asbestos warning signs). At each site a sample was placed on a tripod or on equipment near the breathing zone of an average-sized person.Sixty-one area asbestos
samples were taken among the 4 plants; 12 of these had concentrations greater than the limit of detection (0.003 f/cc). Two of these samples were collected at
Plant 1, 3 at Plant 2, 1 at Plant 3, and 6 at Plant 4. The values ranged from 0.003-0.007 f/cc and were below the OSHA PEL of 0.1 f/cc.

Trucks lined up just off site waiting to collect a load. While waiting to advance in line, truck drivers spent varying amounts of timesitting in their trucks, walking
along the street, and walking onto the site in proximity to the pile. Once they reached the front of the line, the trucks were directed onto the site alongside of
or directly into the debris. Later in the cleanup effort, trucks were driven into the excavation pit where they waited for a load. If the wait was more than a few
minutes, the drivers routinely got out of the trucks and walked around the edges of the pile or pit. Since each load was carefully inspected for evidence and human
remains prior to leaving the site, truck drivers typically spent extended periods of time on site waiting to receive a load. Early in the cleanup effort,loaded trucks
were driven directly to a landfill where theywere emptied of their contents. They were then driven backto the site to be reloaded. In early October, the process
waschanged. Loaded trucks were driven to a nearby pier wheretheir loads were emptied onto a platform. The debris wasthen transferred onto a barge for transport
to the landfill andthe trucks were returned to the site for another load. (p. 3)

Median AHERA airborne asbestos personal air sampling results for each of the three sampling periods were similar, ranging from 0.012 to 0.017 s/cm3. The
highest individual sample was 0.10 s/cm3collected during the week of 10/01/01. However, the collection period for this sample was only 3.33 hours due to pump
failure...Personal airborne fiber exposures assessed using PCM weremeasured during the two October sampling periods (Tablell). A total of 33 samples were
analyzed using PCM. Medianairborne fiber concentrations ranged from 0.01 to 0.04 f/cm3,Only one sample exceeded the OSHA asbestos PEL of 0.1 f/cm3.The
sample concentration equaled 0.11 f/cm3 and was collected over 580 min. (p. 5)
A total of 50 samples were collected and 5 were too overloaded with particulate matter to be analyzed. The airborne concentrations were highest in the last
sampling period of October 2001, (median area concentration of 0.03 s/cm3), followed by the first week in October 2001, (median area concentration of 0.005
s/cm3). The majority (79%) of area air samples collected in April were below the limit of detection. All structures observed during area air sampling were
chrysotile. (p. 5)
Of the asbestos structures detected, all but one were chrysotile, and very few (4%) were >5 nm in length, (p. 5)

Building demolition: several large (90 m x 36 m) wool storage warehouses were demolished at Site 8. The first of these (8. I) was demolished by removing
wall sheets and structural bracing and then collapsing the structure with roofing sheets intact. The roofing sheets sustained little damage and subsequently were
removed by several workers who formed a chain across the roof and passed and dragged the sheets to each other and finally to two men stacking them on a platform
up to chest height. Other warehouses were demolished by removing all cladding from the standing structure with workers confined to platforms adjacent to wall
sheets or in scissor lifts set at a height such that roofing was at chest level. Work conditions were more confined in these trials and involved closer contact with
weathered sheeting. Handling of roofing sheets was visibly dusty - particularly as they were stacked in the tray of the scissor lift. (4/10) Asbestos concentrations
during building demolition were measured only for the period of sheet handling, and they are presented in Table VII. Sheet handling was continuous and much
more vigorous than for roof replacement work. Generallysheeting was removed at a rate of 100 m2/man-hr in demolition work as compared to 5 to 10 m2/ man-hr
for the roof replacement process. Building demolition appeared to create considerably more visible dust emission and short sampling periods (30 to 60 min), were
employed to limit particulate contamination on filters and to allow comparative trials on the same day. (7/10)

Roof replacement: old and badly weathered AC roofing was replaced by steel roofing on large commercial buildings (Sites 3 to 5, 7) or housing (Site 6) as normal
building maintenance procedures. Roof replacement usually was carried out by two to six men, according to a sequence whereby small sections (20 to 40 m2)
were repetitively unfastened, removed and replaced by new roofing. Sheets were removed whole and carried individually to the edge of roofs where they were
either stacked (Sites 3,5,7), dropped directly into a bin atground level (Site 4), or passed and stacked into the tray of a truck (Site 6). After removal of large areas
of roofing, the stacked sheets either were lifted from the building by crane (Site 5) or dropped individually into a dump bin at ground level (Sites 3, 7). Trials

Area sampling data:
The aim of this study was to investigate the concentrations of airborne asbestos that can be released into classrooms of schools that have amosite-containing
asbestos insulation board (AIB) in the ceiling plenum or other spaces, particularly where there is forced recirculation of air as part of a warm air heating system.
Air samples were collected in three or more classrooms at each of three schools, two of which were of CLASP (Consortium of Local Authorities Special
Programme) system-built design, during periods when the schools were unoccupied. Two conditions were sampled: (i) the start-up and running of the heating
systems with no disturbance (the background) and (ii) running of the heating systems during simulated disturbance. The simulated disturbance was designed to
exceed the level of disturbance to the AIB that would routinely take place in an occupied classroom. A total of 60 or more direct impacts that vibrated and/or
flexed the encapsulated or enclosed AIB materials were applied over the sampling period. The impacts were carried out at the start of the sampling and repeated
at hourly intervals but did not break or damage the AIB.
Inhalation
Fibers
The PCM fibre concentrations were all below the LOQ but analytical TEM showed that few of the fibres counted in the background samples were asbestos.
The background TEM air concentrations for individual samples from all three schools with warm air heating systems for asbestos fibres were at or below the
AS (0.0001 f ml—1). A more vigorous disturbance in School C, by directly striking the AIB panels on heater cupboards and under the windows -100 times in
each classroom over a 2-h sampling period, released airborne PCME amosite fibres with short-term concentrations of up to 0.0043 f ml—1 with a pooled average
of 0.0019 f ml—1 for the four classrooms giving measurable releases. The level of disturbance used was considered to replicate a peak exposure event from
disturbances which did not damage the AIB.

Worker activity description: Asbestos removal from 6-floor teaching block was conducted in 2 phases. Phase I saw the removal of asbestos from the top 3 floors during an Easter vacation,
refurbishment being carried out at intervals during the following 26 weeks. Phase 2 saw the removal of asbestos from the lower 3 floors during the summer
vacation, some 12 weeks later. Refurbishment took place over the following 9 weeks. Buildings contained sprayed trowelled amosite insulation behind a false
ceiling of non-asbestos perforated tiles.
Area sampling data: Although no samples were taken inside the enclosure during the dry removal of the asbestos, airborne concentrations of theorder of 1-50 f/ml were likely. A
single sample (0.29 f/ml), taken in the stairwell adjacent to an enclosure, demonstrated that some leakage was occurring. Samples taken after the removal had
been completed and the areas cleaned and vacated, gave measurable concentrations of amosite fibres. The levels recorded in both phases of removal decayed with
time, although in phase I the refurbishment activities initially generated higher airborne concentrations. Samples taken 9 weeks after reoccupation, during normal
activities, gave average amosite concentrations of 0.0004 f/ ml in both phase I and phase 2 areas, slightly above the levels found before any asbestos was removed.

Worker activity description:
Area sampling data:
The building was of steel frame and concrete panel construction and all the steel members had a covering of about 30 mm of amosite-based insulation. Activities
included maintenance, dry removal, and surface stripping.
Only one sample was taken inside an enclosure during stripping and was very heavily loaded, with an estimated fibre concentration of 10-30 f/ml. As found at
other sites, there was measurable leakage from the plastic enclosures during asbestos removal. It was also found that outdoor samples taken close to the building in
an approximately downwind position gave increased levels when the ground floor and the first floor were being stripped.As the building was left vacant for some
months without refurbishment, the effect of disturbing the floor dust was also monitored. The vinyl floor coverings had been removed during the final cleaning of
the building,leaving an unsealed concrete surface. In the course of a detailed visual inspection, several areas were located where traces of amosite material were
suspected. In the first exercise, dust on shelves and a small floor area where contamination was expected was moderately disturbed with a hand brush for less than
I min. On a separate visit, dust was vigorously disturbed by heavy sweeping with a broom for 5 min in suspect areas.

Area sampling data: The concentrations of airborne asbestos fibres measured in the areas adjacent to the 20 buildings in which extensive asbestos cement roofing was found. Among
these, 2 roofs were public buildings, 11 industrial buildings, and 7 industrial disused sites, which showed roofing in visibly advanced states of degradation. The
pull-up test applied to public and industrial buildings judged the roofs as very poor. The air samplings were performed at a height of -1.5 m from the ground
and at a distance of ~3-4 m from the building. The mean wind velocity was always very slow of ~l-2 m si. Building Type# Investigated# Air samplingCmean

Typical samples, collected for 26 hours, have shown levels of lessthan 0.005 f/cc during removal operations. Other samples collected in the "controlled areas" by
Major have not exceeded the OSHA PEL of 2 f/cc. [PDF Pg. 13]
All workers in the "controlled area" wore contamination control disposal coveralls and half-face mask respirators with high efficiency dust cartridges. As
mentioned in the Major Training Manual, failure to wear respiratory protection in the "controlled area" is grounds for immediate dismissal from employment.
This safety precaution was well monitored. [PDF Pg. 12]
The HEPA exhaust system, located in the "controlled area" was apparently effective in maintaining a negative pressure in the control area and, thereby, preventing
external contamination. The 9-1/2 inch exhaust duct (0.5 square feet) was removing approximately 500 cubic feet of air per minute (cfm) from the work area.
However, its effectiveness could have been improved by locating replacement air inlets closer to the potential dust sources.A water proof, portable fluorescent
work drop light, manufactured by KB Industries of Angola, New York was demonstrated. Since most removal operations involve copious quantities of water on
both work surfaces and workers, stray electric currents are a constant hazard. Positive ground faults interrupters properly grounded equipment and water-proof
devices are essential for safe operations.The three module, mobile Detox unit, developed by Bill Major, (Evergreen Industries) permits excellent personal hygiene
practices by removal personnel. It appeared to be well designed and extremely functional. It is noted that an additional modual section on the clean dressing room
end would have improved utility by providing space to store street clothing. [PDF Pg. 13]

reported quite high exposures from field cutting of A-C pipe more than ten years later. Exposures from repair work on A-C pipes using high-speed disc cutters
inside and outside holes dug in the ground to gain access to the pipes were recorded as: 49-170 f/cc (mean value 92) inside the hole, and 1.7-15 f/cc outside." (pg

The duration of the sampling was normally 8 h or, in some cases, fraction of this period, whenever it was necessary to obtain different information on same phase
of reclamation, (pg 71)
In all phases of reclamation, workers were equipped with respiratory masks, particularly demi-mask with P3 filters and Tyveks clothing, (pg 71)
Each yard, both confined and open, was controlled by monitoring the possible dispersion of fibers in the environment (inside the plant) and the exposure of those
who worked during the reclamation phase, (pg 71)

At the hospital, workers did laundry near asbestos insulated steam pipes. (4/37) At the sugar factory, workers were performing maintenance on processing
equipment for the next harvest season. This included the removal of lagging (troweled-on insulating covering) from some of the equipment. (11/37)

(PCM) There were 10 air samples collected at the Queen Elizabeth Hospital, including one outdoor sample as a control. Four samples showed fiber concentrations
above the LOD. One of these was the control sample, which was collected in a large open area between the hospital laundry and the hospital proper. Two samples
from the laundry showed fiber concentrations of 0.005 f/cm3 . One was located next to the TULLIS sheet iron and the other next to the AJAX steam irons
(northeast side). One sample, collected in the hospital boiler room near the fire pump tank, showed 0.004 f/cm3 . The outdoor air sample fiber concentration was
0.006 f/cm3 . At the Bulkley Sugar Factory, only one of the 10 samples analyzed by PCM showed fiber concentrations above the LOD. This sample was collected
in the evaporation area where 0.016 f/cm3 were found. Three of the samples collected at Bulkley were overloaded. There was a lot of activity in the areas where
the samples were collected, and it was much dustier than the other survey sites. (11/37)
35 workers in the hospital laundry room, 98 workers at the sugar factory. (4/37)
NIOSH recommended that all friable asbestos be replaced using enclosures and wet methods, followed by wet cleanup methods. (15/37)

Geographic isolation, soaking of the asbestos source, and personal containment represent the most important strategies for reduction of exposure. (7/17) The site
is kept at negative barometric pressure (relative to the surrounding area) by having fans blow air outward through HEPA filters. If possible, asbestos-containing
material is covered in plastic bags to encase escaping fragments. Throughout removal, every effort is made to keep the material soaked so that respirable dust

Worker activity description: asbestos-composite wallboard cut with powered tools (pg 4) Additional exposure may occur indoor or outdoors with the gradual release of asbestos fibers from
deteriorating building materials, (pg. 4)Construction workers who install asbestos-containing materials may be exposed during the cutting and drilling of building
materials such as cement pipe or tiles (pg 5)Because the fibers released by these activities are highly durable, can remain airborne for long periods and can be
re-suspended in air with the disturbance of settled dust, building construction workers (such as electricians, masons, and carpenters) who do not work directly with
the asbestos-containing materials may be exposed sufficiently to cause asbestos disease, (pg 5)the process of removing asbestos-containing materials can lead to
further, significant exposure. This may occur in the ship breaking industry, where decommissioned ships insulated with asbestos are torn apart for scrap metal,
releasing the asbestos into the work and general environments. In addition, if old asbestos-containing materials remain in place beyond their functional lifetime,
they may release hazardous fibers into the breathing air of those working or dwelling within the buildings (pg 5)
In a survey of four large-scale asbestos cement factories studied by NIOH, two with a predominance of manual operations had mean fiber levels less than 1

Ten metal casting rings approximately 28 mm in diameter and 35 mm long (no. 4805, Whip Mix Corp.) were placed approximately 46 cm in front of the
investigator.Individual pieces of dry asbestos liner approximately 90 mm long, 38 mm wide, and 0.6 mm thick were torn from rolls and manually adapted to the
inside circumference of the ring. The strips were torn to approximately the distance between two measured (90 mm) lines, when all 10 rings were lined, the
asbestos liners were removed and placed in a plastic waste bag; disposal of the liners was in contrast to actual laboratory use, where the liner wouldhave been
saturated with water instead of subjected to further manipulation. The rings were again lined as before, and the process was repeated for a total time of 30 minutes.
The experiment was repeated three times in sue cession to yield three separate BZ samples,

Parameter Data
Area sampling data: Sheet-Metal Workers' Exposure to Asbestos: Asbestos fiber ( f ) concentrations as high as 100 f/cc were measured in the spray zone during construction. (P.
3/15)Measurements of air levels during such renovation demonstrate that sheet-metal workers may have the heaviest exposure of any members of the construction
crews with 8-hour time-weighted averages of 0.19 f/cc," with past exposure probably significantly higher.
Personal protective equipment: Respirators and protective clothing represent inferior solutions to the asbestos problem and have serious limitations which are well established in the literature of
industrial hygiene.The powered air-purifying respirator (PAPR) provides a higher protection factor than the normal air-purifying respirator and is cooler and more
comfortable to wear since the positive pressure reduces breathing resistance. (P. 10/15)
Engineering control: The protocol includes wet handling techniques along with the use of a HEPA vacuum (high efficiency particulate absolute) for surface and floor clean-up. (P. 8/15)

"Water is the key to controlling the fugitive dust and thus asbestos emissions from construction materials. Application techniques vary from a sophisticated spray
system attached directly to the rock-cutting or drilling equipment, to strategically aiming a water hose at a work activity or employing a water truck to spray the
entire work area and haul roads. All exposed and excavated material must be kept damp to preventthe release of asbestos fibers into the air. The variable rate
fogger nozzles employed in fighting petroleum fires are an excellent tool for this purpose. The fogger nozzle produces a wet mist that knocks down airborne fibers,
and water consumption can be controlled by the operator. (3/8)"

2, 6 and 8, where there is a possibility of exposure. In WCS2 all 6 measurements were below the level of detection (approximately 100 fibres/m3 ). In WCS 6 the
measurements (n=2) were below the level of detection. In WCS 8 all 6 measurements were below the limit of detection. For calculation of the statistics the level
of detection as such was used as the result of the measurement. Details of the exposure data are given in annex 1 to the opinion. For the other WCSs minimal
(or no) exposure is expected: The asbestos is fully sealed for WCS1. In WCS3 workers are controlling the process from a remote position (control room). Also
WCS4 and 5 are fully closed processes. The workers control this from a remote position. For WCS7 the concentration in the room is very low due to local exhaust
ventilation and a high level of hygiene. Also the workers are protected by personal protective equipment (PPE) including powered respirator with efficiency of
97.5 %. Exposure scenario 2 for workers: Use in diaphragm cells (closed systems)This scenario consists of one Environmental contributing scenario (ECS) and 7

only available for WCS 2, 6 and 7. In WCS2, 4 out of 6 measurements were below the level of detection (approximately 100 fibres/m3 ). In WCS 6, 4 of 9
measurements for dismantling were below the level of detection. For cleaning of anode/cathode one result was below the level of detection, the other two were at
the level of detection. In WCS 7 all 6 measurements were below the level of detection. For calculation of the statistics the level of detection as such was used as
the result of the measurement. Details of the exposure data are given in annex 1 to the opinion. For the other WCSs minimal (or no) exposure is expected: The
asbestos is fully sealed for WCS1. In WCS3 the asbestos is bound in matrix, and the diaphragm itself is not handled so the probability of exposure is very low.
WCS4 is a fully closed process as the cells are fully closed during its service life, and no exposure is foreseen. Also in WCS5 the cells are fully closed, and during
storage submerged in water, preventing release of fibres. There is a need for continuation of the restriction and the associated risk management measures already
in place in order to minimise risk of possible exposure to chrysotile asbestos for workers in the two companies. Also, a continuation of the restriction will prevent
other companies from initiating import and use of chrysotile asbestos, a substance that is known to be carcinogenic to humans,

During the activities with a main potential for exposure e.g. cleaning and maintenance, the workers wear disposable protective clothing and a full face mask (in
accordance with EN136:1998) with a powered air filtering unit with P3 filter cartridge (fulfilling EN 12941:1998/EN12942:1998). As general personal protective
equipment all workers wear safety clothing and protective safety gloves, as well as helmet and safety shoes. For activities in the asbestos handling room, the
shower room must be used and the employees wear disposable clothing.
No environmental assessment has been conducted for either of the two exposure scenarios, as there is no release of asbestos to environmental compartments.
Release to air is prevented by the use of ventilation and negative pressure as well as the use of HEPA filters before emission. This is confirmed by measurements at
the stacks were the air is released in 2010, 2011 and 2013 which all were below the detection limit (<100 fibres/m3). The background level of asbestos in outdoor
air in Germany is in the range of 100 - 150 fibres/m3. Used HEPA filters are collected and destroyed at the site. All waste water possibly containing asbestos
enters a closed waste water treatment system. The fibres in the waste water are destroyed on-site.

Dell and Teta reported a sole measurement taken from an industrial hygiene report from 1968 [LaFrance, 1968] of dust levels between 8.7 and 20.1 million particles
per cubicfoot (mppcf). Other than the 1968 monitoring, UCC reported results in f/cc. The exposures ranged from 0.3 to 14.1 f/cc; however, all measurements
were under 5 f/cc except for 14.1 f/cc when an operator was dumping five bags of phenolic molding compound 5,303 containing 30% Canadian 7RF9. The worker
was wearing a respirator at this time and all other samples (of 10 total) taken in different departments were between 0.8 and 5 f/cc [Bradley, 1972; Kleber, 1973],
The samples referenced by Dell and Teta were taken atthe charging station where asbestos bags were dumped into a hopper [LaFrance, 1968], UCC reported the
results as a percentage of the "allowable dose," which was 5 f/cc in 1974,Other similar samples taken by UCC over the next 5 years indicate that the samples were
short-term (<15 min), and not time-weighted averages (TWAs) [Cope, 1972; Kleber, 1973], None of the results exceed 5 f/cc TWA.In 1974, UCC tested mixer
operators dumping raw asbestos from bags, the charge roll operators shoveling raw mix onto the rolls, and the CBS bag packer [Neal, 1974], Eight-hour TWA
exposures during bag dumping were between 1.3 and 1.6 f/cc [Neal, 1974], The exposures of the charge role operators were "satisfactory" ranging from 0.7 to 1.1
f/cc "...despite rather frequent shoveling of raw mix onto the rolls during monitoring" [Neal, 1974], Finally, the CBS bag packer exposure level was "negligible"
at 0.3 fibers per milliliter [Neal, 1974], UCC required workers in this area to wear respirators, although not all complied [Neal, 1974],

The storeroom was first occupied by the firm about five years ago. At that time, there were many exposed pipes covered with a white, flaky substance which the
firm's president assumes was asbestos. The room was cleaned by the president and two helpers. [PDF Pg. 4]
Airborne asbestos fibers were not detected on the filtersamples (limit of detection was approximately 0.05 fiber per cubiccentimeter of air). [PDF Pg. 7]
No respirators were worn during cleaning of the storage room. [PDF Pg. 4]
To prevent any asbestos contamination from the damaged overhead pipe covering , it is recommended that the pipe covering be repaired with fibrous glass batting
and duct tape. [PDF Pg. 8]
Exposure duration not given in document. Three samples of airborne dust were collected on 37 millimeter "AA" filters at a nominal flow rate of 1.5 liters per

Asbestos stacked 100 pound pressure packed bags stacked on wooden pallets sealed with transparent shrunk wrapped plastic, making it impossible for broken
bags to leak unless the outer film is punctured, but this can be easily repaired with pressure sensitive tape. Broken bags can be resealed and spilt material can be
picked up using a central industrial vacuum cleaning system.Fully automated bag opening and empty bag compacting machine receives bag into a hopper from a
conveyor and after being centered in the machine by retractable rollers, the bags are cut completely in half lengthwise, the two haves are drawn apart and after
the contents have been emptied. The halves are drawn into an automatic bag compactor and ejected into extended plastics tubs that can be tied off an when full
and disposed of safely. Exhaust ventilated conveying and transfer systems are designed to eliminate excessive asbestos exposure of plant workers, and effluent air
filtration systems were employed to avoid emission of fibers into the environment.During the transfer of the product from the mixer to the transfer tray , flexible
hose is needed to connect to exhaust system. To remove fibers from exhaust, filter bags pretreated with asbestos floats (a grade of short fine diameter asbestos) to
provide the highest collection efficiency. Modular vacuum-cleaned HEPA filter unit to clean exhaust air. Automatic pulse jet cleaning, where collected material
are deposited into an airtight drum that is close coupled to a automatic air lock at the base of the dust hopper.

noted that the low-pressure steam lines were insulated with ACM. Damage to the pipe insulation covering, observed near the heating units, caused friableasbestos
to be exposed in the vicinity of the heater" (pg 19)
Static air samples with minimal activity in the area: "Analytical results indicated levels that were well below the present occupational exposure limit of 0.2 fiber
per cm3 of air in an 8-h work period. However, based on the visual inspection results, employees performing work within the containment shell could be subjected
to significant airborne asbestos exposures. For example, activities such as cleaning of floors, equipment maintenance, and climbing to or walking within the

There are six types of mineral silicate fibers, together referred to as asbestos. Ninety-five percent of the asbestos in the U.S. is chrysotile, a white curly fiber that
is easily woven into protective clothing and heat insulation products. Amosite, the second most common, was used in fireboards, friction products, and fire hoses
especially during the 1950s and 1960s). Amosite and anthophyllite are rectangular fibers. Crocidolite, a strong, blue, needlelike fiber, was used in asbestos cement
and briefly in a cigarette filter. Amosite, anthophyllite and crocidolite are classified with the remaining two fiber types (tremolite and actinolite) as members of
the amphibole group. Chrysotile is the only member of its own group; it is a pyroxenes or serpentine asbestos, (pg 1 of 12)
As indicated in Table 1 (pg 2 of 12), different concentrations (fibers/cc) are as follows: indoor air (depending if asbestos is used in building materials) - 0.0003-
0.06; dry sweep of a library floor with asbestos containing ceiling material - 10; removing asbestos-containing ceiling section in a library - 17 - 34.
Because asbestos is crystalline, very small fibers can break length-wise and form even smaller diameter fibers (less than .25 microns or l/100,000ths of an inch),

There were 44 male and 10 female asbestos workers and 22 male and 12 female controls.
Workers are almost exclusively exposed to chrysotile asbestos. Source was marked for area sampling data but I never saw any sample data for samples taken at
the plant. All sampling data was of lung tissue which I chose to add that data in the chemical concentration section.

Fibre counts in the building by light microscopy suggest a baseline of 0.01 f/cc and peaks on the order of 0.1 f/cc during renovation work (pg l)Sampling of air
in office buildings in Ontario and Alberta have generally yielded levels in the range of 0.01 f/cc for fibres of all length, and 0.003 or less for fibres >= 5.0 nm.
When the airspace above suspended ceilings has been examined, total counts less than 0.01 f/cc are typical by either optical or electron microscopy. (Optical
microscopy is not accurate at such low levels.) If maintenance or renovation work is carried out without special precautions, total fibre counts as high as 0.18
have been recorded,although this total count still represents < 0.02 for fibres >5.0 nm (pg 2)Baseline levels before and after renovation were 0.01 f/cc and below.
During renovation, counts ranged from undetectable to as high as 0.86 on one occasion, probably an unusual incident, and averaged 0.07. During renovation
work, airborne asbestos levels in the renovation areas themselves ranged from undetectable to 0.09 f/cc except for two unusually high counts (0.25 and 0.13) that
probably represented unusual events. Average counts were 0.01. Before and after renovation, counts were consistently 0.01 and below in the renovation areas, (pg

[PDF Pg. 3]Lagging: The application a nd removal of heat insulating materials is mainly concentrated in the machinery spaces aboard ships and present practice
is to lag all hot faces above I 50°F with calcium silicate sections covered with asbestos cloth. Cutting and fixing sections, rope and cloth docs give rise to localized
high dustconcentrations, but the highest dust concentrations occur during removal of old lagging material.Asbestos spraying: This process was extensively used for
environmental insulation until 1963 when it was completely discontinued. The existing material is extensively removed during refits and is being replaced by glass
fibre. The dust concentrationsduring removing the dry material arc very high.Application of sound insulation: Asbestos boards of various types and thicknesses
have been sawn and fitted for sound insulation and removed during subsequent refits. This work is done by joiners, and again the highest dust concentrations occur
during removal of the old material.

Workers were not required and were not observed to wear protective equipment during the preparation stage, primarily covering the pipes with poly. When
removal activity was started in a room, all workers were required to wear disposable coveralls and half face mask cartridge respirators equipped with high
efficiency cartridges.
Potential sources of asbestos dust were controlled by enclosing the pipe lagging in plastic sheeting before removing it from the pipes. Plastic glove bags were used
to enclose and collect the pipe lagging during removal activities. The pipe lagging was wetted with amended water prior to, during, and after its removal from the
pipes. To prevent general contamination of the school building by dust from the removal operations in the study areas, overlapping plastic curtains were placed on
all doors to halls or other rooms. Additionally, all ventilation registers and windows were sealed with plastic sheeting and tape, removable furniture and fixtures
were also covered with plastic sheeting.

The data are for an occupational scenario within the scope of the risk evaluation.
Metadata on the operations, equipment, and worker activities associated with the data
show that the data agree representative of outdated operations, equipment, and activities
rather than current operations, equipment, and worker activities. The data are more than

UK Breathing zone samples from firefighters of both new and old helmets with unlined asbestos cloth covers were analyzed and had fiber concentrations of 2.30

Municipal fire 2.7 f/cm2 (mean); Fire Training 0-2.3 f/cm2 from helmets and fumes of fire fighters.
Estimated time spent inside structural fires broken down by tasks for two fire departments in Arizona, USA. The results were: entry/ventilation 5.7 ± 11.7
hour/yr (Phoenix), and 3.5 ± 3.7 hour/yr (Tucson); rescue 5.0 ± 8.0 hour/yr (Phoenix), and 2.1 ± 2.7 hour/yr (Tucson); knockdown (extinction) 5.6 ± 8.9

hour/yr (Phoenix), and 19.1 ± 76.7 hour/yr (Tucson). Total firefighter activity at fires in Phoenix and Tucson was a mean of 47.6 hour/yr and 50.0 hour/yr,
respectively.In a study among firefighters in Washington, DC, (n = 43), at the time of the survey, an average of 9.2 days had elapsed since the last fire. Also,
0.33 fires had been fought in the previous 24 hours, 1.33 in the previous week, 5.91 in the previous month, and 57.1 fires in the previous yearApproximately
90% of municipal structural fires are either extinguished within 5-10 minutes, or abandoned and fought from the outside. This results in an average duration
of heavy physical activity at fires of approximately 10 minutes. Knockdown of large fires may last much longer. During overhaul, any remaining small fires
are extinguished. The environment during overhaul is not as hot or as smoky as during knockdown, but it still contains products of combustion from small
fires or smoldering material. Exposure can differ widely between the twophases of firefighting. The determination of when overhaul begins varies from one fire
department to another, and is often left to the judgement of individual firefighters or group leaders, firefighters work 10 to 24 hour shifts for 188 days per year

Parameter Data
Area sampling data: Airborne fiber concentrations and worker exposure to fibers in the newer building were assessed to be insignificant, (pg 476) High levels of fiber concentrations
were observed in places, where brake pads were cleaned with compressed air, wire brushes, or a similar method. One study reported that airborne fiber concentra-
tions did not exceed the regulatory limits (0.1 fiber/cm3 air for 8 h TWA) in repair shops during brake maintenance of most vehicles. Another study found fiber
concentrations of up to 125 fibers/cm3 of air during cleaning of brakes from buses and trucks with compressed air, while this number was 8.2 fibers/cm3 during
maintenance of passenger cars. Overall, average concentrations were between 0.1 and 0.2 fibers/cm3 for an 8 h TWA for truck and bus maintenance, and less than
0.05 fiber/cm3 for passenger cars. . Overall, average concentrations were between 0.1 and 0.2 fibres/cm3 for an 8 h TWA for truck and bus maintenance, and less

Comments: The air samples were collected on 25-mm, 0.4-um pore-size, Nuclepore polycarbonate filters. Each 25-mm filter was mounted on a 5-um pore-size, mixed
cellulose ester, backup diffusing filter and cellulose support pad and was contained in a three-piece cassette with a 50-mm conductive cowl and face cap. The filter
assembly was attached to an electric-powered vacuum pump operating at a flow rate of 8 to 12 liters per minute to achieve a minimum air volume of approximately
3000 liters.The polycarbonate membrane filters were analyzed by transmission electron microscopy (TEM). The filters were prepared and analyzed for asbestos
fibers by TEM in accordance with the Yamate Revised Method. 3 A TEM Level II analysis was performed on all polycarbonate samples collected in this study.

These air samplers were calibrated using a cyclone jar before and after the sampling
period (NIOSH 0600). The determination of airborne fiber on the membrane filter was
undertaken through the use of a microscope with a phase contrast (NIOSH 7400). Phase
contrast microscopy accurately assessed the level of exposure for fibers 5 jUm in length

plate press line in hot metal shop - gatherer, presser, two carry-in people, a foreman's helper, and a separator:"The gatherer uses a long-handled rod to extract
about 4 lbs of molten glass from the continuous tank furnace and drops it on to a press. The presser forms the plate. Next carry-in person #1 transfers the plate to
a carbon holder using a scoop. Carry-in #2, using asbestos gloves, stacks the plates in columns of 3 with 4 small irregular shaped pieces of 1/4 inch asbestos mill
board separating each plate. Carry-in #2 removes his gloves to transfer the column of 3 plates to the hot end of the #2 lehr using a long-handled paddle. The lehr
is a temperature controlled enclosed conveyor belt used to slow the cooling of newly formed glassware. This slow cool process prevents the glass from cracking.
The lehr's inlet temperature of 9000F drops 500F for every 6 feet the belt moves. Resident time in the lehr is 2 hour and 45 minutes. At the cold end of the lehr
(800F) a separator removes and prepares the plate for shipping. The small 2 to 5 inch irregular shaped pieces of asbestos mill board are dropped into a 3 foot
sauare cardboard box. When the box is full it is returned to the beginning of the plate press line to be reused in the plate stacking process. These asbestos pieces
are used until they deteriorate or are lost. About once a month the foreman's helper must break new pieces of asbestos mill board by hand. He performs this task
outside in open air. The mill board is received in 42 x 48 inch sheets, (pg 4)"dry sweeping to clean hot metal shop increases airborne asbestos (pg 5)

In the roof of the Hot Metal Shop there were four 42-inch general exhaust fans each with capacity ratings of 14,780 CFM. One was not in operation during the
survey. Two garage sized doors and three standard sized doors are open to the outside in the Hot Metal Shop. Also there is an air intake port outside the building
that supplies a manifold which circles the continuous tank furnace. The manifold delivers air primarily for cooling purposes. This along with the open doors and
exhaust fans insure that air changes in the building are frequent. A floor fan is used to provide air movement on the plate press line. This probably increases
asbestos exposures by blowing free fibers into the air that workers breath, (pg 5)

Average 8-h TWA was estimated to be 0.009 f/cc for a mechanic and 0.006 f/cc for a bystander. (P. 13/19)
The average/airborne chrysotile concentrations as measuredby PCM, TEM, and PCME were 0.053, 0.087, and 0.024 f/cc, respectively, for the Stockton mechanic
and 0.338, 0.012, and 0.010 f/cc measured by PCM, TEM, and PCME, respectively, for the Big Rock mechanic (Table 2). (P. 9/19)The average airborne asbestos
concentrations measured on the volunteer (handling the clothes) were 0.231, 0.011, and 0.036 f/cc when measured by PCM, TEM, and PCME, respectively.
Likewise, at the bystander location, average asbestos concentrations of 0.093, 0.012, and 0.010 f/cc were measured using PCM, TEM, and PCME, respectively
(sampling times were 30 min in duration andcollected during the anticipated peak times of exposure). (P. 13/19)
Within the worker samples, there were 261 total asbestos fibers counted using the ISO methodology. Of these, only 36% were free fibers or bundles, 18% were
free fibers or bundles with diameter,0.7 um (length . 5 um) and only 2% were free fibers or bundles with diameter ,0.7 um and length .20 lm. The remaining fibers
were either in clusters (3%) or attached to a matrix (61%). Only 3% of the fibers, however, were part of a cluster that may be respirable (,10 um in width), and
36%of fibers were part of a matrix that may be respirable.

Table 1 presents asbestos concentrations for short term (30 min) samples, using PCM, and TEM. During all valve work, personal sampling concentrations for the
main workers were 0.059+-0.033 f/cc for PCM and 0.014+-0.018 f/cc for TEM. (5/16) Table 3 presents asbestos concentrations for long term (60 min) samples,

Table 4 presents area asbestos concentrations during valve work. Concentrations were 0.0019+-0.0012 f/cc for PCM, and 0.0005+-0.0003 f/cc for TEM. (8/16)
In general, the mechanics took approximately 15-40 min to replace the packing material and approximately 10-30 min to replace the gasket, thus resulting in a

The operators were working on the fourth level floor and were removing thermobestos block from the top of the hot air duct. The operators started the job by
picking up the hot insulation and placing it on a six by eight foot piece of plywood. The material had to be cooled down with a stream of water. The thermobestos
was inserted into plastic bags which were secured with tape. The bags had the "Caution Asbestos" warning printed on the front. The job cycle included the arc
welding of pins to a wire system and installing two layers of 2"x24"x48" Delta board over the system. Wire mesh was cut and installed over the insulation. The
job was difficult due to the excessive heat the operators were exposed to.

"The airborne level of fibers during removal averaged 16.4 f/cc with dry methods, but remained under 2 f/cc with wet removal. In another study, airborne fiber
levels from the time of initial erection of barriers to final clearing rose to 37 f/cc. Dry removal resulted in a mean level of 38.9 f/cc, untreated water removal 28.6
f/cc and EPA-amended water methodology 1 f/cc. Bagging of the debris resulted in a higher airborne contamination (3.8 f/cc)(2/3)"
Excellent maintenance of existing asbestos-containing building materials is the most appropriate action. Encapsulation with sealants such as latex paint, or
complete occlusion of trouble spots may be necessary. Protecting easily-damaged areas with sheet metal is the rule in the shipbuilding trade. The use of bonding
agents by injection can stabilize areas prior to repair and painting. These techniques are also valuable in buying time until asbestos can be removed in a well-
planned maneuver. (3/3)

Comments:
The overhaul was performed in accordance with accepted industry standards, and with the guidelines published in the Pratt & Whitney engine manuals. The
exception was that upon completion of the overhaul, the engine was not returned to flight readiness. While all engine components were reassembled, some
time-consuming procedures normally part of an overhaul, principally installation of safety wiring, disassembling and weighing each individual blade from each
compressor and turbine section, rebalancing each compressor and turbine section, testing the integrity of parts, rebalancing moving parts, torqueing of bolts,
alignment testing of bearings, and balancing of compressor and turbine vane assemblies were not performed. This had no effect on the assessment of airborne
asbestos exposure since no asbestos-containing part removal, replacement, or disturbance is associated with these activities. Overhaul The overhaul took place
over a three week period. During the first week of the project, the mechanics disassembled the JT3D engine. The disassembly work took approximately 6-7
business days. No work was done during the intervening weekend. The disassembly was conducted in accordance with the procedures set forth in the Pratt &
Whitney engine manuals (Pratt and Whitney, 1997), and accepted industry standards. Weeks two and three of the project were spent reassembling the engine.
Reassembly proceeded in reverse from disassembly, and was conducted in accordance with the procedures set forth in the Pratt & Whitney engine manuals, and
accepted industry standards. Original replacement parts were used whenever possible. During the period of time between disassembly and reassembly, no work
was performed on the engine or any of its components, except that all the appropriate large, metal pieces were cleaned. Cleaning of these components is a normal
part of an overhaul, and presents no opportunity for asbestos exposure. Accordingly, no air sampling was performed during this period of time. Gear box rebuild
Once removed from the engine, the gear box for most jet engine types, including the JT3D, is typically rebuilt in a separate area, concurrent with the remainder
of the engine rebuild. The gear box for this engine was rebuilt in this fashion. It was taken to a separate room, described earlier, and a mechanic whose specialty
is this type of work performed the rebuild. The gear box rebuild was done in one day. On the same day, and in the same room, some minor components of the
engine such as the fuel control, the fuel pump, and the fuel oil cooler, were rebuilt as well. Separate personal air samples were collected during the rebuild of the
gear box and other components from the mechanics that performed the work. Area air samples were collected in proximity to this work in conjunction with the
overhaul, as were samples from the two outdoor locations. (P. 3/6)

342-432 min) and spraying asphalt emulsion (0.01-0.3 f/cc; sample duration not provided) (pg 2)1986-1991: removal of asbestos-containing roof flashings,
mastics, coatings and cements yielded low asbestos fiber concentrations (range, 0.004-0.027 f/cc; mean, 0.024 f/cc); no samples exceeded 0.1 f/cc (pg 2)1982:
0.1 to 0.6 f/cc during tear-out and replacementof roofing materials (pg 2)1987: demolition in old Australian buildings ranged from 0.02 to 0.60 f/cc (pg 2)1987:
Exposures of <0.1 to 0.22 f/cc were measured when the roof surface was painted or cleaned with a water jet for several hours. During roof replacement (including
unfastening, removal and disposal of roof sheets), concentrations ranged from below the limit of detection to 0.32 f/cc, with estimated TWAs ranging from 0.03
to 0.21 f/cc (pg 10)

Personal protective equipmentln general, the use of personal protective equipment (PPE) as a control measure should be limited to situations where other control
measures are not practicable or where it is used in conjunction with other measures to increase protection.PPE used by chrysotile product manufacturers in Australia
include: • respiratory protection (e.g. half-face mask respirators with class M cartridges or 3M 8710 respirators); • safety glasses or goggles in designated eye
protection areas or on designated machines (e.g. grinders); • cotton overalls; and • gloves for handling of materials.In most gasket workshops, overalls were worn
by all employees. All brake bonding shops and one service garage reported that respiratory protection was used during times of potential exposure to asbestos.
During site visits it was observed that a 3M 8710 mask was used during cutting and grinding of brake linings (in brake bonding) and during the changing of brake
linings (service garage).NSW WorkCover has published a guidance document on the use of personal protective equipment (NSW WorkCover, 1996). Personal
protective equipment should be selected according to manufacturers/suppliers recommendations, usually available in the MSDS.Gasket manufacture: workers
wear cotton overalls, half face mask respirators (with class M cartridges) and leather gloves when handling chrysotile or conducting equipment maintenance
operations.Epoxy resin manufacture: At the time of the survey, 17 workers were employed at the site, around half of which were engaged on the factory floor and
storage areas. Workers wear 3M 8710 respirators when handling and weighing asbestos. Gloves are worn by all factory floor workers.

Engineering control: Engineering controlsEngineering controls are plant construction or processes which minimise exposure to hazardous substances such as ventilation, enclosure
(closed process) and automation.The three manufacturers of chrysotile products in Australia have various engineering controls in place at their manufacturing
sites. These controls include:* dust extraction systems which operate during different stages of the manufacturing process;* automated process for the opening and
removal of the woven polyethylene bag which contains the raw chrysotile and disposal of the bag;* mixing vessels enclosed and operated under negative pressure;*
automated decanting of asbestos mixes and machining of final product* localised automated dust extraction; and* centrally ducted vacuum systems.

Padding steam engines with insulation material. Placing mineral wool containing asbestos around a steam boiler. The steam boilers were maintenanced every
6 years and broken up after 25 years of service. Insulation would be loosed and some asbestos torn out and spread around. After being disposed, asbestos
was brushed away with long steel brushes.Passenger coaches were spray-insulated with crocidolite between 1961-1971. Heating equipment was insulated with
yarns of chrysotile wound around the pipes. Same with the exhaust pipes. Dust came from dismantling old and dry asbestos. Water tanks were insulated with
crocidolite. Ventilation pipes contained amosite and amosite mixed with chrysotile was used in air conditioning equipment.Punching of gaskets from sheets of
asbestos, changing of break lines in electric engines, and insulating with asbestos powder in the casing and insulation of the electrical works of the engines.
Inhalation, dermal (from dust settling)

Estimates of exposures were not actually calculated but scores from (0) - no asbestos exposure; (1) irregular exposure of low intensity; (2) regular, low exposure;
(3) medium exposure; and (4) heavy exposure. Expected ranges for these exposures were: (1) was 0.5-1 fiber/mL; (2) was 1-5 fiber/mL; (3) was 5-10 fiber/mL; and
(4) was 10-20 fiber/mL. Workers in insulating steam engines were scored a (4). Average workshop exposure was scored in 3-5 fiber/mL which falls in exposure
(2). Passenger coaches were scored a (4).
1,650 workers in 1949. Decreased to 620 employees in 1980. A total of 5,000 men had been employed here between 1902-1980.
Source is for exposure among railroad workshop workers. Asbestos exposure is from crocidolite, chrysotile, and amosite over the years.

and then a finer, 120-grit sandpaper).Removal: Styrofoam boardscoated with fully dried test product were cut into narrow strips (0.25- 1.5 in wide) using a utility
knife, fine-toothed saw, and wallboard saw. The cut pieces were removed by hand or by scraping with a putty knife.Sweep cleaning: A hand-held bench brush
was used to remove debris-coated with test product (remaining from the removal test) and from the table on which the testing had been performed. A broom and
dustpan were used to clean the debris from the floor of the testing area. All debris was placed in a garbage can.

during the following activities: background, handling welding rods, welding with four types of asbestos-containing electrodes, and the broom sweeping of dust
and debris following welding operations. Using TEM, no asbestos fibers were detected in any of the personal or area samples (Millette 1994a, 1994b). (pg 26)
In addition, "worst-case" use simulation studies, specifically intended to generate airborne flux particles, reported that airborne asbestos concentrations were
either undetectable or very low. The airborne concentrations generated were always below the current OSHA permissible exposure limit (0.1 f/cc TWA) (pg

Respirators are necessary when the exposures exceed either standards or evaluation criteria. Respirators should not be considered a primary control and should only
be used in conjunction with the engineering controls described earlier. For the asbestos exposures evaluated in this study, three types of respirators are approved
. the first is a HIOSH/MSHA approved negative pressure-type respirator (half or full face) with a highefficiency pre-filter for asbestos levels below the current
OSHA Standard. It should be noted that HIOSH currently recommends against the single-use, disposable type respirators while working around asbestos.The last
two respirators include the approved NIOSH/KSHA, powered-air purifying respirator and the NIOSH/MSHA type-C supplied-air respirator. These two respirators
are intended for use during emergencies or during exposure to asbestos levels which exceed the current OSHA Standard, the reader is referred to OSHA 1910
. 1001 for further information on this regulation.When reviewing the respirators described above, it becomes apparent that the half or full-face respirator is the
better choice. However, these can only be used if the dust suppression system is used routinely.lt should be also understood that under OSHA 1910.134, if it has
been determined that respirators must be worn, a complete program of selection, maintenance, and fit testing of the respirators are required.
Engineering controls are the preferred method for decreasing potential exposures to toxic substances and should be used whenpossible. Therefore, it is recom-
mended that the company requirethe use of the water suppression system regardless of the time ofyear.

site during or shortly after mineral fibers have been sprayed" (pg 6)... "The two most important sources for workman exposure during spray operations are (1)
material that becomes airborne during the spray operation (overspray), both that which remains at the job site and that which blows into the surrounding air, and
(2) material that remains on the site because of poor housekeeping." (pg 9)
fiber counts per cubic centimeter provided from other studies: spraying of thermal insulation at power house turbine ranged from 5 to 100 f/cc across three
measured workmen; spraying of fireproofing in multistory building ranged from 20 to 99 f/cc across two measured workmen.... " large spread in counts can be
attributed to differences in asbestos content of material, work proficiency, and the ever-changing conditions on construction sites[.] These dust levels are much
higher than those at asbestos work sites in other trades" (pg 5)
"On-site samples taken at various distances from the nozzle show fiber counts ranging from 70 f/cc 10 feet from the nozzle to 3 f/cc 25 feet away. Counts taken
30 minutes after completion of spray still ranged from 1 to 4 f/cc, and 60 minutes after, from 0.25 to 0.76 f/cc. Again, these counts vary because of changes in
on-site ventilation"; area samples provided for spatiotemporal variation of spray application (pg 6 and 7)
In the United States, more than 3,000,000 men are regularly employed in the building trade
"because of the high fiber counts, 100 f/cc, a conventional filter-type respirator will not provide adequate protection for the worker handling the spray nozzle or
for other workers in the enclosure. In such areas, some type of supplied air respirator must be used" (pg 13)

During the period renovation was in progress, 116 measurements of airborne asbestos by optical microscopy were made in areas outside that being renovated.
During renovation, counts ranged from undetectable to as high as 0.86 f/cc on one unusual occasion, and averaged 0.07 f/cc. In the renovation areas themselves,
airborne asbestos levels ranged from undetectable to 0.09 f/cc except for two unusually high counts of 0.25 and 0.13 f/cc that probably represented unusual events.
Average counts were 0.01 f/cc. Before and after renovation, counts were consistently 0.01 and below in the renovation areas. (3/4)
Respirators and protective clothing. A half-face mask is specified for Type 1 or Type 2 asbestos removal. A powered air-purifying respirator system is needed for
Type 3 removal of amosite or crocidolite or power cutting of any type of asbestos fiber. (2/4)
To prevent dust release, asbestos cement products should not be cut, sanded or drilled with power tools, and joint compounds made prior to 1978 should not be
dry sanded. (1/4) When vacuuming asbestos products, only vacuum cleaners equipped with H.E.P.A. (High Efficiency Particulate Air) filters are the most reliable

respirators were available prior to 1950 and noted for dust baghouse socking shaking in the 1940s, note these older respirators were designed for protection from
PM not fibers.
The intent of this study is to take a close look at those who may have been exposed to asbestos and should be removed from a separate study investigating
silica-lung cancer mortality rates. The detailed assessment identified that a larger portion of the workforce at this site were exposed to Asbestos, the plan being
investigated stopped handling asbestos in 1977. Note this is a recreated assessment of earlier exposure (1920-1940 and 1951-1977) and may not be representative

The highest geometric mean concentration of asbestos (44.2fibers/ cm3) was found when grinding brake linings using a band grinder, even though a local exhaust
ventilator was in use. The geometric mean asbestos concentrations during the attaching of linings to brake shoes and the attaching of facings to clutch disks were
0.859 fibers/cm3 and 0.780 fibers/cm3, respectively. The heaviest exposure observed during the attaching of brake linings to shoes (4.80 fibers/ cm3) was due to
drilling the lining. The heaviest exposure observed during the attaching of clutch facings (3.15 fibers/ cm3) to clutch disks was due to the riveting on of a clutch
facing. (P. 5/12)See Table 3, pgs 7-8/12
Highest geometric mean concentration of asbestos (1.253 fibers/cm3) was obtained during the operation of attaching clutch facings to disks. The geometric mean
concentration exceededthe occupational exposure limit (0.15 fibers/cm3) in the following operations: drilling holes in clutch facings, grinding brake linings with
a grindstone, stripping worn brake linings and clutch facings, attaching brake linings to shoes, visual inspection and packaging,and gluing linings to brake shoes.
The asbestos concentration in a locker room in factory B was 1.72 fibers/cm3. (P. 7/12)See Table 4, pg. 9 and Table 5, pg 11/12 for literature reported values

Personal sampling data: Note: Including whole portions of text for context (e.g., dates important to 9/11 cleanup sampling, analytical methods)Seven of these samples were collected
indoors with two being additionally analyzed via ATEM analysis. Three of the seven were personal air samples with the remaining four being ambient air
samples. One of the three personal air sample results returned a result greater than 0.01 f/mL (0.023 f/mL), which triggered analysis by ATEM. The ATEM
analysis of those fibers observed by PCM did not confirm the presence of asbestos (pg 62)One hundred seventy-eight (178) PCM samples were collected outdoors
on September 15, 2001, with twenty-five (14%) of those samples additionally analyzed by ATEM. 51 of the 178 outdoor samples collected were ambient air
samples with the remaining samples representing personal air samples... Outdoor personal air sample results range from none detected to 0.105 f/mL, which
triggered 25 of them to be further analyzed by ATEM. The ATEM data for the outdoor personal air samples detected asbestos in 3 of the 25 (12%). These ranged
in concentration from 0.012 to 0.017 f/mL. (pg 62-63)OSHA data also exists for the period of September 23, 2001 through April 3, 2002. In all, 548 ambient and
664 personal air samples were collected. The data is not clear as to whether they represent indoor or outdoor environments; we will assume that the majority of the
data represents the outdoor environment... All but 22 of the 664 (3.3%) personal air samples were less than 0.01 f/mL, with the results ranging from 0.01 to 0.073
f/mL (pg 63)The NYS Public Employee Safety & Health (PESH) Program collected asbestos air samples during four separate occasions... For the period ending
November 29, 2001, six personal air samples were collected and analyzed using the NIOSH 7400 methodology, which counts total fibers that meet a 3:1 aspect
ratio and are 5|im or greater in length. All six samples returned results greater than 0.01 f/mL, but less than 0.1 f/mL... On December 18, 2001, three additional
personal air samples were collected and analyzed via NIOSH 7400. Two of these samples returned results greater than 0.01 f/mL, but less than 0.1 f/mL... On
January 30, 2002 a total of 2 personal air samples were collected by NYS PESH and analyzed via NIOSH 7400. The results of the two personal air samples were
greater than 0.01 f/mL, but less than 0.1 f/mL... The final period of sampling conducted by PESH ranges from March 12, 2002 through April 20, 2002 in which
a total of 23 air samples (8 ambient samples and 15 personal samples) were collected and analyzed using PCM and the NIOSH 7400 methodology... fourteen of
the fifteen personal samples were equal to or greater than 0.014 f/mL, but less than 0.1 f/mL. Only one personal sample was reported as being "not detected",
(pg 65)The arithmetic mean of personal asbestos exposure to Search & Rescue worker's was calculated to be 0.009 af/mL. In conducting this calculation airborne
asbestos fiber determinations using ATEM were used instead of total fiber counts by PCM. These calculations also used zero where no asbestos was detected
using ATEM. The worst-case Search & Rescue worker asbestos exposure was evaluated at 0.2 f/mL collected from an ironworker on September 28, 2001, just
one day before the Search & Rescue operations would cease. However this result was downgraded by ATEM analysis as the majority of the fibers counted using
PCM analysis were not asbestos. The true worst-case asbestos related exposure was determined to be 0.07 af/mL after conversion. This sample represented a
personal air sample collected by OSHA on a laborer on September 25, 2001. (pg 72; proceeded by cumulative exposure calculations)Site Clean-up and Recovery
activities were initiated on September 30, 2001, and lasted through March 30, 2002. The arithmetic mean of personal asbestos exposure to the Clean-up &
Recovery workers was 0.0007 af/mL. Similarly, in conducting this calculation, airborne asbestos fiber determinations using ATEM were used instead of total fiber
counts by PCM. This calculation also used zero where no asbestos was detected using ATEM. The worst-case personal air concentration collected during the
Clean-up and Recovery activities was 0.8 f/mL, which was downgraded to zero by ATEM as none of the fibers counted using PCM were asbestos. The true worst
case asbestos-related personal exposure to any Clean-up and Recovery worker was 0.05 af/mL on an air sample collected by OSHA on March 27, 2002. (pg 73;

Note: source calls a lot of this data "ambient" sampling, I guess because it's area sampling outdoors. Assuming this is in-scope as area sampling due to nature

collected indoors with two being additionally analyzed via ATEM analysis. Three of the seven were personal air samples with the remaining four being ambient

using the AHERA methodology. In total fifteen (15) samples were collected, of which nine (9) or 60% exceeded 70 s/mm2 (pg 66)Pg 66-67 has school and
residential exposure sampling, out-of-scope The arithmetic mean of ambient asbestos air sampling conducted during the Search & Rescue operations was 0.015
af/mL. In conducting this calculation, similar to the personal exposures above, airborne asbestos fiber determinations using ATEM were used instead of total fiber
counts by PCM. These calculations also used zero where no asbestos was detected using ATEM. The worst-case ambient air concentration collected during the
Search & Rescue operations was 0.2 f/mL (total fibers) and was collected by the NYCSCA on the intersection of Murray & West Streets on September 15, 2001.
The greatest airborne asbestos determination was also made on September 15, 2001 and was 0.1 af/mL. This determination, that is specific for asbestos was used
in the exposure calculations to follow, (pg 72; proceeded by cumulative exposure calculations)The arithmetic mean of ambient air sampling conducted during the
clean-up and recovery activities were 0.003 af/mL. In conducting this calculation, similar to the personal exposures above, airborne asbestos fiber determinations
using ATEM were used instead of total fiber counts by PCM. These calculations also used zero where no asbestos was detected using ATEM. The worst-case
ambient air concentration collected during the Search & Rescue operation was 0.9 f/mL, which was downgraded by ATEM to zero as none of the fibers counted
using PCM were asbestos. The true worst-case ambient exposure was evaluated at 0.03 af/mL collected by OSHA on October 5, 2001. (pg 73; proceeded by
cumulative exposure calculations)

The above referenced preliminary air data has been examined, and synthesized into three main potential exposure groups: an 18-day exposure group for emergency
workers that conducted Search & Rescue activities, and who arrived onsite on September 12, 2001, the day following the collapse of the WTC as the National
Guard slowly allowed additional workers around Ground Zero which formally ended on September 29, 2001; a 182-day exposure group for Clean-up and Recovery
workers, which formally ended on March 30, 2002; 250 work days/year (pg 70)

capability of released fibers. A surfactant is used to produce amended water to both thoroughly penetrate the friable material and reduce the amount of water
required for adequate wetting.

Study by the National Roofing Contractors Association (NRCA) found in over 1500 individual monitoring results and several thousand personal breathing-zone
samples between 1986-1991, none exceeded 0.1 fibers per cubic centimeter. Table 3 on page 8 provides 30 minutes asbestos PBZ. The total range of values is
between 0.004-0.24 fibers per cubic centimeter. The same table also provides 30 minutes chrysotile PBZ. The total range of values is between 0.005-0.05 fibers
per cubic centimeters
Previous study conducted by the National Roofing Contractors Association (NRCA) indicated removing asbestos-containing roof flashings, mastics, coatings, and
cements yielded low asbestos fiber concentrations [range: 0.004-0.027 fibers per cubic centimeter; mean: 0.024] (1994)A 1982 study found airborne asbestos
concentration of 0.1-0.6 fibers per cubic centimeter during tear-out and replacement of roofing materials however the type of material during tear-out and replace-
ment was not specified.A 1987 study from Australia estimated TWAs during building demolition for old buildings as 0.02-0.6 fibers per cubic centimeter.The
8-hr TWAs are provided in Table 4 on page 10. The range of values for total asbestos fibers is 0.005-0.011 fibers per cubic centimeters. The range of values for
chrysotile fibers is 0.001-0.002 fibers per cubic centimeter.
The products tested as part of this study are no longer manufactured. They were "C-8 Plastic Roof Cement and B-10 Fibered Roof Coating" from "Mon-
sey and Henry".Analytical method was NIOSH 7400 and 7402.Study simulated weather conditions for up to a year before taking airborne level concentra-

Area sampling data: [PDF Pg. 13]Machinists and mechanics (10 samples): 0.001-0.774 (f/cmA3).Samples from two workers operating planting machinery (onefrom each plantation)
had low concentrations (0.017 and 0.018 fibers/cc) of asbestos.Bagasse tractor driver had a single airborne asbestos concentration of 0.77 fibers/cc. Two additional
samples on this same worker, taken sequentially on the same day found no detectable asbestos fibers.
Comments: Samples for inorganic fibers were collected on 25-mm cellulose open-faced filters with conductive cowls. Stationary and personal breathing zone samples were
collected at a flow rate of 3 1pm. Analysis was performed using transmission electron microscopy (TEM) at 10.500X magnification for sizing and counting fibers
with a length to width ratio of 3:1 or more. Energy dispersive X-ray probe analysis was used for confirmation of the elemental constituents of each fiber. Bulk
cane leaf and bagasse dust analysis for inorganic fiber identification and counting, free of an organic matrix, was performed by weighing a given amount of dried
leaf, ashing this, and suspending an aliquot of the ash in solution to be distributed on a 25-mm filter. One hundred fields in the resulting filter preparation were
examined, and all fibers which met the width to aspect ratio of 1:3 were counted at a microscope setting ofl0,500X magnification. Fibers in which silica was not
a primary constituent were not counted. [PDF Pg. 4]

The greatest number of workers was found in the construction industry and in private households where such personnel was hired. (2/5)
inhalation (2/5)
fibers (2/5)
(PCM) The average concentration of asbestos fibers in workplace atmospheres was 0.02 f/cm3 in the energy industry, 0.03 f/cm2 in the machinery production
industry, 0.03 f/cm3 in the construction industry, 0.07 f/cm3 in the chemistry industry, and 0.13 f/cm3 in the transportation industry. (3/5)
The greatest danger comes from inhalation asbestos fibers which are longer than um and with a diameter less than 3um and with an aspect ratio <=3. (2/5)
Worldwide, millions of workers are asbestos-exposed in their workplaces, most often when asbestos-containing building materials are handled, repaired or replaced
. In Lithuania, the number of potentially exposed workers is as high as 7500. The greatest number of workers was found in the construction industry (3100 (44%))
and in private households where such personnel was hired (2300 (33%)) (2/5)

it varied between 0.036 and 0.215 fibers/ml.If the gasket proved difficult to remove or broke in the process, it was left for group B.The average fiber concentration,
as determined by PCM, ranged between below the detection limit and 0.02 fibers/ml. When this is converted to an 8-h limit, then the value ranges from below the

WorkPractices for Removal of Resilient Floor Coverings"
OSHA average 91 hours per year per building on O&M work involving active exposure to asbestos.O&M means a program of work practices to maintain asbestos
in good condition, ensure cleanup of asbestos fibers previously released, and prevent further release by minimizing and controlling asbestos disturbance or
damage. O&M is needed regardless of whether the asbestos present is friable or nonfriable, intact or non-intact, since the potential exists for it to become friable
or non-intact.
Personal protective equipment: Author noted that the follow are not required if concentrations are less than PEL: safety glassesglovesprotective clothingrespirators (in confined spaces) the
document specificially states that a respirator is not needed for floor removal as there is an agreement that these activities do not exceed the PEL.
Engineering control: WR Grace supposedly has developed a foam that can seep into asbestos to "digest" the fibers within 24 hours (fluorine, in ionic form, reacts selectively with
chrysotile asbestos fibers, breaking them down into inert inorganic matter). This product was anticipated to be available in 1998.

In 2006 and 2007 the Environmental Protection Agency (EPA) conducted three tests to examine the cost and environmental effectiveness of Alternative Asbestos
Control Method (AACM). Two tests were conducted in Fort Chafee, Arkansas and one was conducted in Forth Worth, Texas. The EPA discontinued testing the
AACM due to technical deficiencies. The AACM remains unapproved and should not be used.

Sampling data is experimentally measured area monitoring from dry- and wet-vacuuming artificially contaminated asbestos carpeting. [PDF Pg. 2]Real-world

asbestos from aging and deteriorating ACM relates to several factors, such as the condition and amount of asbestos present, the accessibility of the material,
activity within the area, vibration, temperature, humidity, airflow, use patterns, etc." [PDF Pg. 1]

Parameter Data
Worker activity description: Insulatorslnsulators work in virtually every type of industrial, commercial, and institutional location. In shipyards, these workers were often called laggers,
pipe coverers, or pipe coverers and insulators(PC&I). Their primary job function is to apply insulating materials to exposed surfaces of structures such as pipes
and ductwork, storage tanks, or other mechanical systems to help control and maintain temperature and provide personal protection against contact with high-
temperature surfaces. They are responsible for applying insulating materials, such as fiberglass, foam rubber, styrofoam, cork, urethane, asbestos, or mineral
wool, based on heat-retaining or heat-excluding characteristics. Insulators brush adhesives on or attach metal adhesive-backed pins to flat surfaces to facilitate the
application of insulation material, or bind wire netting over the insulating material in place and clip metal bands or wire to pipe insulation to secure it to the pipes.
They measure and cut insulation materials to specified sizes and shapes for covering flat or round surfaces and then attach required insulation material around or
to the structures according to specifications. Once insulating materials are pressed into place, insulators coat pipe insulation and joints with asbestos cement and
wrap them with cloth or cotton duck cloth to form a seal. In some industries, insulators may install firestopping for both electrical and mechanical systems.The
specific tasks performed by insulators have been categorized as (1) cutting and shaping insulation materials using hand or power saws (prefabrication); (2) mixing
of mineral wool, asbestos or fibrous glass cements (mixing); (3) installing or fitting amosite, chrysotile, or both amosite and chrysotile insulation block or sections
of pipe covering using wire or asbestos cements or spraying asbestos-containing insulation materials (application); (4) coating insulation materials with cements,
resins, cloth, or sealers (finishing); (5) dismantling or tearing out unusable materials while insulating or re-insulating (removal); and (6) the cleaning up of old
insulation and debris and transporting insulation materials (cleanup). Most of these tasks created the potential for significant exposure to asbestos if they were
performed in Naval shipyards or involved the spraying of asbestos.PipefittersThe primary job duties of pipefitters are to assemble, install, maintain, and repair
many different types of pipelines or pipe systems. This includes the installation and repair of high- and/or low pressure pipe systems, as well as automatic
controls, which modulate the flow of fluids in the various pipes and vessels. These pipe systems may carry water, steam, air, or other liquids or gases that are used
in manufacturing, in the generation of electricity, and in heating and cooling of buildings. Some pipefitters specialize in only one type of system; for example,
steamfitters install pipe systems that move liquid or gases under high pressure and/or high temperature. Pipefitters select the type and size of pipe and related
materials and equipment, such as supports, hangers, and hydraulic cylinders, according to plans, blueprints, or instructions. They typically cut, thread, and bend
pipe or tubing (by hand or machine) prior to assembling and installing a variety of metal and nonmetal pipe and pipe fittings. They connect pipes using threaded,
caulked, soldered, brazed, fused, or cemented joints and hand tools and secure pipes to structures with brackets, clamps, and hangers. Pipefitters install and
maintain hydraulic and pneumatic components of machines and equipment, such as valves, pumps, and cylinders, as well as refrigeration and air-conditioning
systems. They inspect work sites to determine the presence of obstructions and to ascertain that holes cut for pipes will not cause structural weakness, and
sometimes test piping systems for leaks or weld holding fixtures to structural steel members. In shipyards, pipefitters install and maintain ships' piping systems,
layout pipe sections, cut and bore holes in bulkheads and decks for installation of pipes, operate shop machines to cut and thread pipe and pipe fittings, and
perform repairs to valve, pumps, and controls.Most pipefitter tasks can be categorized as (1) working on piping in the field (installation or repair); (2) installing
or fabricating gaskets for use in piping, valves, pumps, and other equipment to prevent the leakage of fluids between solid surfaces (preformed or gasket making -
the fabrication of gaskets, which could include hand punching, mechanical punching, machine punching, machine shearing, and machine nibbling); (3) removing
and replacing gaskets and the packing from pumps and valves (gasket and packing removal); (4) performing general work in the field or shop area (pipe shop);
and (5) performing general cleanup and maintenance work (cleanup). WeldersWelders join metal parts by applying heat to metal pieces and melting and fusing
them to forma permanent bond. Welders also join steel beams when constructing buildings, bridges, and otherstructures, and join pipes in pipeline systems, power
plants, and refineries. Welding may be manualor semiautomatic, and arc welding is the most common method by which metal is joined (soldering and brazing are
similar processes used for specialized applications). Welders use specified electrodes and insert electrodes into portable holders or thread consumable electrode
wire through a portable welding gun. They manually guide electrode or gun along weld line and examine the weld for bead size and other specifications. They
may manually apply filler rod to supply weld metal and clean or degrease weld joints or workpieces or remove paints and coatings ahead of the weld. Welders
also perform related tasks such as flame cutting or grinding. Scarfing or gauging were tasks that were commonly performed during shipbuilding and repair,
in which a copper jacketed carbon road and ligigllecSifc ©inMi^ere used to melt and "gauge" away the metal away. Welders also sometimes repair broken

Worker activity description: InsulatorLaborer MasonMaintenancePipefitterBoilermakerMillwright Carpenter Welder Sheet-MetalElectrician Painterlnsulators - The primary job function of
insulators is to apply insulating materials to exposed surfaces of equipment, such as boilers, tanks, hot or cold air ducts or pipes, steam generators, or ductwork
(or other mechanical systems), in order to help control and maintain temperature. According to an API (1972) report on the petroleum refining industry, insulators
are responsible for selecting the type of insulating materials, on the basis of heat-retaining or heat-excluding characteristics. It is also the insulator's job to bind
wire netting around the object being insulated to hold the insulating material in place (prior to applying one or more coats of insulating material), and to clip
metal bands to pipe insulation to secure the insulation on pipes. Once insulating materials are pressed into place, insulators coat joints with cement and wrap them
with cloth tape to form a seal.Insulators spent the majority (>50%) of their time installing or fitting insulation block or sections of pipe covering (application)
and coating insulation materials with cements, resins, cloth, or sealers (finishing). Insulators spent another 15-30% of their workday (1) cutting and shaping
insulation materials (blocks or reformed pipe insulation) or working in the general shop area (prefabrication/ shop); (2) mixing mineral wool, asbestos, fibrous
glass, and cements; (3) cleaning up old insulation and debris and transporting insulation materials; (4) and walking around and bidding on projects at the work
site.Pipefitters - Pipefitters are responsible for fabricating, assembling, installing, maintaining, and repairing many different types of piping and piping systems,
fixtures, and equipment for steam, hot water, heating, cooling, lubricating, and industrial processing systems. Pipefitters typically cut, thread, and bend pipe or
tubing (by hand or machine) prior to assembling and installing a variety of metal and nonmetal pipe and pipe fittings. These tradesmen also install and maintain
refrigeration and air conditioning systems and test piping systems for leaks, and sometimes weld holding fixtures to structural steel members. At this refinery,
pipefitters were qualified to handle any type of pipe, including both high- and low-pressure pipe systems carrying water, steam, air, or other liquids or gases.
Specialized steamfitters, such as those working on highpressure lines in shipyards or other petroleum refineries, were not required at this refinery.Some of the
tasks performed by pipefitters at this refinery may have had the potential for exposure to asbestos. Specifically, these tradesmen spent approximately 60% of their
time installing or repairing piping or pipe systems in the field and working in the shop area, and 5-10% of their time performing general cleanup work. Pipefitters
spent another 3% of their time fabricating gaskets for use in piping, valves, pumps, and other equipment and 5% of their time removing or replacing gaskets and
packing from pipes and valves.WeldersWelders join metal parts by applying heat to metal pieces and melting and fusing them to form a permanent bond. Welders
in various industries use both gas welding or brazing and any combination of arc welding processes (API, 1972). Welders are also responsible for performing
related tasks, such as flame cutting and grinding, and sometimes repair broken or cracked parts, fill holes, and increase the size of metal parts. At this refinery,
welders were primarily responsible for joining pipes using both manual and semiautomatic methods depending on the type of steel welding. The primary activity
in which these tradesmen was involved (welding) did not involve exposure to asbestos. Welders may have come into contact with asbestos-containing materials in
the past due to the handling of blankets, gloves, and mats (which would have taken about 20-30% of their time). For example, asbestos blankets were historically
used at the refinery to keep pipes from cooling too rapidly (i.e., during "heat treating" when new piping was installed and welded) and to contain sparks and
protect welders from getting burned. Starting in the mid-1970s, nonfriable materials such as fiberglass were substituted for asbestos in welding blankets. Although
no historical measurements have been found during the handling or use of asbestos-containing blanks, simulated work with asbestos gloves yielded average fiber
concentrations ranging from 0.07 to 0.99 fibers/cc. A few welding rods could also have been coated with asbestos-containing flux. Welders typically spent about
5 to 10% of their time working on "hot" or "very hot" pipes at the this refinery, except during new construction, during which time they would have been near
asbestos-containing insulation.Sheet-Metal Workers- Sheet-metal workers fabricate, assemble, install, and repair sheet-metal products and equipment. At this
refinery, these craftsmen typically worked with sheet metal for HVAC (heating, ventilation, and air conditioning), ducts, control boxes, drainpipes, and furnace
casings, but may also have sometimes worked with fiberglass and plastic materials. Although some workers may have been involved in putting preassembled
metal jackets around insulation, this task was typically performed by insulators. Because their primary tasks at the refinery involved (1) fabricating sheet-metal
projects, (2) installing and repairing old sheet-metal, and (3) removing old sheets, sheet-metal workers would have experienced minimal exposures to asbestos
over most time periods. These craftsmen may have had some contact with asbestos-containing materials during the removal of old ducts that were wrapped with
asbestos paper (this would have been a very infrequent occurrence, accounting for less than 2%of their time).Boilermakers - The primary duties of boilermakers
are to make, install, repair, and clean boilers, tB08pv28^®f

Exposure duration: According to an unpublished report of insulators in the petroleum industry in the late 1930s, these workers typically spent about 60% (or less) of their working
time exposed to materials that may have contained asbestos. Published studies of insulators in the construction industry during the 1960s and 1970s also indicated
that these workers spent only about 45% of their time working with asbestos materials.Of all crafts, insulators were estimated to have spent the most time working
with or around such materials (at least 40% of their time prior to 1972), followed by laborers (at least 25% of their time prior to 1972). Because of their work
involving the installation of firebrick (which may have entailed contact with asbestos-containing mortar or surrounding insulation), masons were also estimated
to have spent more time working with asbestos-containing materials than the other trades (at least 5% of their time prior to 1972). Several crafts (sheet-metal
workers, welders, electricians, carpenters, and painters) were estimated to have had very little contact with asbestos-containing materials during all time periods.
For all crafts, the time spent working with asbestos-containing materials at the refinery was estimated to have decreased significantly after the early 1970s, and
particularly after the mid-1980s, when specialized abatement workers would handle most activities related to asbestos insulation.Insulator 1940-50 45-60 % time

personal monitoring was undertaken on a subject wearing anasbestos apron and gauntlets while carrying objects and doing bench work (p.l-2)personal airborne
fibre exposure from wearing asbestos safety coats, hoods, gloves and leggings was measured for workers at two ore reduction plants. The men working on furnaces
prepared channels along which molten iron flowed, tapped the furnaces andkept the channels clear of slag during casting. (p.2)A second survey was undertaken
at a small plant manufacturing elemental phosphorous where four men carried out work similar to that at the steel works. Asbestos safety coats and leggings were
worn throughout the slagging operations but hoods and gloveswere worn only when necessary (p.2)
inhalation
Lab study: The airborne fibre concentrations measuredin their six tests ranged from 2.4 to 4.2 fibres/ml, with amean airborne fibre concentration of 3.5 fibres/ml.
(p.2)At the steel works, the mean airborne fibre concentrationmeasured during the 39 personal monitoring tests was 2.0fibres/ml, with a range from 0.3 to 5.0
fibres/ml, based ona mean sampling period of 52 minutes. The analysis ofthese data suggested that the fibre release increased withage of the garments up to 8
weeks, although the numberof measurements was too small and the correlation coefficient too low to reliably predict fibre release from garments of different ages.
(p.2)At the phosphorous manufacturing plant, the mean personal airborne fibre concentration measured by personal sampling was 14 fibres/ml. This was based
on 6 tests and a mean exposureperiod of 35 minutes. The measured airborne fibre concentrations ranged from 9.9 to 26 fibres/ml. The reason for the considerable
differences in measured airborne fibre concentrations between the two plants was not known, although Gibbs suggests the higher levels were because the coats
and mittens in the phosphorous plant were untreated (i.e., not aluminized outside or dust suppressed) and leggings were also quite badly damaged, (p.2)
In the studies performed on workers in their actual workplaces, air samples were collected from the breathing zone of each worker and 75 cm above the tabletop
where the gloves were laid or tossed.The mean time weighted average (TWA) concentrations ofairborne fibres from the 176 measurements in the isolation chamber,
ranged from 0.95 to 12 fibres/ml. The minimum TWA concentration measured was 0.61 fibres/ml for well-worn and heavily soiled gloves. The maximum TWA
concentration measured was 16 fibres/ml for wellworn and clean gloves. The results showed that clean wellworn gloves emitted significantly more fibres than
did brand-new gloves, but fibre emission decreased with increased surface soiling.Eighty air samples were collected during a simulation carried out in the well-
ventilated laboratory. The range of mean TWA airborne fibre concentrations was 0.07 to 0.99 fibres/ml for the personal samples, and 0.06 to 0.60 fibres/ml for the
static samples. Thirteen samples were collected by Samimi and Williamsin actual workplaces. The maximum and minimum TWAairborne fibre concentrations
ranged from 0.07 to 2.93fibres/ml for personal samples and from 0.04 to 0.74fibres/ml for static samples (sampling over an 8-hourshift). (p.2-3)

Area sampling data:
Asbestos abatement actions currently take four forms:removal, encapsulation, enclosure, and operation and maintenance controls (p. l)"In atypical removal action,
the area which containsACM is isolated from the rest of the building using polyethylene sheeting, air locks, and negative pressure ventilation systems. The ACM
is dampened with water and the asbestos is mechanically removed (e.g., by scrapers, wire brushes, brooms, etc.). Once this gross removal has been accomplished,
the surfaces are vacuumed with a High Efficiency Particulate Air (HEPA) vacuum and,often, covered with an encapsulant material. The polyethylene or other
isolation materials are then removed, and the area is cleaned by a combination of HEPA vacuuming and wet hand cleaning. During the removal, personal and/or
environmental air monitoring is performed both by collection of samples for subsequent laboratory analysis and also by on-line, real-time measurements.Following
removal and cleanup, a final inspection and air sampling are performed." (p. 2)

of maintenance personnel to mixed asbestos fibre types due to large quantities of friable asbestos in place. In buildings with control plans, personal exposure
of building maintenance personnel in the USA, expressed as 8h time-weighted averages, was between 0.002 and 0.02 f/ml. These values are of the same order
of magnitude as typical exposures during telecommunication switchwork (0.009 f/ml) and above-ceiling work (0.037 f/ml), although higher concentrations were
reported in utility space work (0.5 f/ml)." (pg 26)

Worker activity description: The employer shall identify a competent person to set up the enclosure, ensure its integrity limit entry and exit, supervise employee exposure monitoring,
ensure that proper protective clothing and respirators are being worn, ensure employees are properly trained, ensure that employees use hygiene facilities and
observe decontamination procedures, and ensure that engineering controls are functioning.The following procedures are recommended for entering and leaving
a contaminated site:for entering and exiting sites: 1. Before entering the contaminated area:- Make sure the respirator is operating properly.- Make sure you have
all materials necessary to conduct the inspectionsafely (e.g., disposable towels, extra plastic bags, spray bottle, etc.). All materials that must be carried into the
work areas should be sealed in a plastic bag to minimize contamination.-If you take a camera into the contaminated area, precautions must be taken to minimize
contamination or to decontaminate the camera. Possible solutions include using a waterproof camera or sealing a conventional camera in an impermeable box.
Both of these methods am used by scuba divers.- Leave all street clothing on. Short-sleeve shirts and short pants are preferable to long-sleeve shirts and long pants.
If you am wearing long pants or long sleeves roll them up.- Don an inner disposable coverall and inner booties (e.g., Tyvep or equivalent) over street clothes.- If
an SCBA is to be used, wear the SCBA with the air valve closed Let the respirator facepiece hang from the neck by the strap.- Don outer disposable coverall. Use
coverall with an expandable back if an SCBA is used.- Don disposable outer boots and gloves. Use duct tape to attach the boots and gloves to the outer coverall.-
Fit the respirator facepiece to the face and open the air valve for an SCBA, and tighten the facepiece straps. If an air-purifying respirator is used, conduct negative
pressure and positive pressure field tests.- Fit the coverall hood snugly around the respirator facepiece.- zip up the suit.- Proceed to the contaminated area and make
inspection.2. Before leaving the contaminated area:- Standing near the exit, HEPA vacuum (if possible) and wet wipe all visible debris from the outer protective
clothing (use a spray bottle containing water and disposable towels to wet wipe the suit; use plenty of water). Standing at the doorway inside the work area, remove
outer protective clothing and immediately step outside the area.3. Outside the contaminated area:- Once outside, thoroughly wet wipe and mist spray the respirator
and inner protective clothing. Move away from the doorway and remove the respirator and inner protective clothing.- Place all disposable materials in a proper
container for disposable.- Seal all contaminated non-disposable materials in a plastic bagand take them with you to decontaminate later.Procedures for entering and
leaving a site where a 3-stage decontamination system is available: 1. Prior to entering he clean room - Determine that the respirator is functioning properly.- Make
sure you have all materials necessary to conduct theinspection safely (e.g., duct tape, disposable towels, protectiveclothing, respirator, extra plastic bags, spray
bottle, etc. ). Allmaterials that must be carried into the contaminated areashould be sealed in a plastic bag to minimize contamination.- If you take a camera into
the contaminated area, precautionsmust be taken to minimize contamination or to decontaminatethe camera. Possible solutions include using a waterproofcamera
or sealing a conventional camera in an impermeableclear camera box. Both of these methods are used by scubadivers2. In the Clean Room:- Remove all street
clothing including socks and underwear andstore in a clean, sealed plastic bag. If desired, wear a bathingsuit (or equivalent) and inner booties. You may prefer to
havethe bathing suit on before going to the site.- If an SCBA is being used, close the air valve and don theSCBA, let the respirator facepiece hang from the neck by
thestrap.- Don disposable full body, hooded coverall. Use a coverallwith an expandable back if an SCBA is being used.- Don disposable outer boots and gloves.
Use duct tape to sealto outer suit.- Fit respirator facepiece to face. For an air purifying respirator,perform negative and positive pressure field checks. For anSCBA,
open the air valve and adjust facepiece straps.- Fit the coverall hood snugly around the respirator facepieceand sip up coverall if not yet done.- Emceed to the shower
area.3. In the Shower Area:- Leave disposable towels (sealed in a plastic bag) near theshower.- Proceed to the contaminated area and make inspection.4. Before
leaving the contaminated area- HEPA vacuum (if possible) and wet wipe all visible debrisfrom protective clothing (use a spray bottle and disposabletowels to wipe

Exposure route: inhalation
Physical form: inhalable fibers
Personal protective equipment: Protective, lightweight garments worn by workers performing asbestos abatement to prevent gross bodily contamination. Respirator - A protective device which
filters harmful substances from air inhaled by workers in a contaminated area. The minimum respirator protection required for asbestos Workers is a half-faced,
dual-cartridge respirator with HFPA filters. Supplied air respirator - A respirator that has a central source ofbreathing air supplied to the wearer by way of an
airline. Half-Musk. Fits over the bridge of the nose, along the cheek, and under the chin. Two head bands form a four-point suspension to hold the mask in place
and maintain the facepiece seal. During inhalation a slight vacuum (negative pressure) is created within the facepiece, causing ambient air to be drawn through
High Efficiency Particulate Air (HEPA) filter media and into the facepiece. The expired air exits through an exhalation valve at thebottom of the facepieceFull-face.
Fits over the face across the forehead, along the temple and the cheek, and under the chin. These devices have a head harness with a 5- or 6- point suspension.
During inhalation a slight vacuum (negative pressure) is created in the facepiece, causing ambient air to be drawn through the HEPA filter media and into the
facepiece. The expired air exits through an exhalation valve at the bottom of the facepiecePowered air-purifying respirators (PAPRs). Have auxiliary battery-
powered, motorized filtration units which blow purified air to the facepiece. Since this creates a slight positive pressure in the mask, any breach in the facepiece
seal should permit only the outward flow of air from the mask, thereby preventing inhalation of contaminated air. Air-line (Type C) respirators. Consist of a
half-mask, full-facepiece,hood or helmet to which Grade D breathing air is supplied through a small diameter, high pressure air line.Air-Line Respirator with Self
Contained Auxiliary Air Supply. This respirator combines an air-line respirator with an auxiliary air supply (SCBA) to provide the user with respirable air if the
main air supply fails. Supplied-Air (Type C) respirator with HEPAjtlter. This respirator system consists of a full-facepiece air-line respirator with a backup HEPA
filter. It allows the user to discamect from the air supply system in an emergency and proceed through standard decontamination procedures while breathing
through the HEPA cartridges. The serf-contained breathing apparatus. Consists of a full- facepiece, regulator, and a respirable compressed air supply. The SCBA
allows the user to carry the air supply, thus eliminating the need for a stationary air supply. The SCBA must operate in the pressure demand mode to be used in
asbestos-contaminated atmospheres The overall protection afforded by a given respirator may be stated in terms of its protection factor (PF) and fit factor (PF),
both of which are defined as the ratio of the concentration of a contaminant in the ambient atmosphere to that inside the respirator facepiece under use conditions.
Protection factors are assigned values which address a certain class of respirators as a whole. In general, they provide an average value which takes into account the
variety of makes and models, and the different facial structures of the user population. Fit factors are specific to a given respirator model and to the individual being
tested. Thus, a respirator given a protection factor of 10 may be used in atmospheres not exceeding levels of 10 times the PEL. The protection factor can only be
applied when a comprehensive respirator program exists and the overall limits of the respirator are known. The Los Alamos Scientific Laboratory was responsible
for determining universally accepted protection factors for all types of respirators:- Not in excess of Two f/cc '(10 x PEL) - Half mask air-purifying respirator
equipped with high efficiency filters.- Not in excess of Ten f/cc *( 50 x PEL) - Full facepiece air-purifying respirator equipped with high efficiency filters.- Not in
excess of Twenty f/cc *(100 x PEL) 1. Any powered air-purifying respirator (PAPR) equipped with high-efficiency filters. 2. Any supplied-air respirator operated
in continuous flow mode.- Not in excess of 200 f/cc *(1000 x PEL) - Full facepiece supplied air respirator operated in pressure demand mode. - Greater than
200 f/cc (>1000 x PEL) or unknown concentration - Full facepiece supplied air respirator operated in pressure demand mode equipped with an auxiliary positive
pressure self-contained breathing apparatus. Fit factors are determined by conducting a separate, quantitative fit test that is specific to the individual and to the
make and model of the respirator to be used. As with protection factors, a fit factor is defined as the ratio of challenge agent concentration outside with respect
to the inside of a respirator inlet covering (facepiece or enclosure). Unlike protection factors, fit factors are determined for negative pressure, non-powered air
purifying respirators only since individual fit testing is not required for respirators with positive pressure at the facepiece.Once a respirator is selected, a positive
and negative "fit check" is performed. A negative pressure "fit check" involves blocking the respirator inlet while inhaling. The positive pressure "fit check"
involves blocking the exhalation valve and breathing out to test the facepiece seal.Quantitative fit testing is also conducted using a challenge atmosphere within
an enclosure, but a probe is attached to the respirator which samples the atmosphere inside the facepiece. Both the atmosphere inside the facepiece and inside
the test chamber are measured using an electronic instrument that quantities the test agent. The ratio of the two values provides a "quantitative" determination
as to how well the respirator fits. The report provides more details concerning the process of qualitative and quantitative fit test along with details about how
respirators should be inspected, cleaned and stored.Protective clothingProtective clothing for asbestos abatement projects usually consists of disposable coveralls,
foot and head coverings, and gloves. 1. A disposable, full-body, hooded, outer coverall (e.g., Tyvek@ or equivalent). A coverall with an expanded back should be
worn with an SCBA. 2. A bathing suit (or equivalent), an inner disposable coverall or disposable undergarments. When possible, particularly when a changing or
decontamination area is available, all street clothing should be removed before donning protective clothing. When clothing is removed, the inspector may choose
to wear a bathing suit under the protective clothing. If it is not possible to remove street clothing, the inspector should toll up pant legs and sleeves and don an
inner disposable coverall. 3. Disposable gloves (PVC or equivalent).4. Disposable inner booties (e.g., Tyvek@ or equivalent).5. Disposable outer booties (taped
to outer coverall).6. Safety helmets or hard hats.7. Safety shoes.Safety glasses- Protective eye equipment

Worker activity description: The largest industrial groups exposed are specialty trade contractors, followed by building construction, automotive repair, and shipbuilding. By occupation, the
largest exposed groups are carpenters and cabinetmakers, followed by construction trade helpers and laborers. Exposure in construction workers is difficult to
monitor due to the wide variety of worksites and the transient nature of employment for many workers. Despite this, the INSPQ in Quebec released a report on
exposures to asbestos in the construction industry. Other occupational groups that may be exposed to asbestos include electricians, plumbers, plaster and drywall
installers, and auto mechanics, (pg 3 of 6)
Exposure route: Inhalation is the most important route of occupational exposure to asbestos, (pg 3 of 6)

gies. There were several mineral varieties of amphibole asbestos present, including (in order of decreasing abundance) winchite, richerite, and tremolite, with
lower levels of magnesio-riebeckite, edenite, and magnesio-arfvedsonite. Some minerals may also be classified as actinolite. The mixture of asbestos present at
the Site is referred to as Libby amphibole asbestos or LA. (pg 1-2)
Though the document mentions collection of personal air samples, the results are not included in this document.
Based on Figure 5-6 (pg 184 of 425), maximum mean air concentrations in Libby was ~1.4e-5 s/cc observed in August and the minimum mean air concentrations
in Libby was close of zero observed in January.
nan
As per Table 6-22 (pg 262 of 425), exposure duration was 30 days/year as reasonable maximum exposure for outdoor workers
no information was available regarding engineering controls

Personal asbestos concentrations based on transmission electron microscopy counts were extremely high, ranging from 0.006 to 3.493 f cm—3 for 8-h TWA and
from 0.015 to 8.835 f cm-3 for 30-min samples.For BRS1, three of the four TWA 8-h personal samples exceeded O.lf cm-3 based on TEM results. BRS2 had
full-shift exposures (based on TEM) that exceeded 0.1 f cm—3. In BRS3, one of the three full shift personal samples exceeded (based on TEM) O.lf cm—3.

Personal protective equipment: For activities involving asbestos only respirators (P2/P3) are used in general. They are divided into: respirators with replaceable filters and with or without a
ventilator; respirators with filters that cannot be replaced, (p. 34)
Engineering control: Sprayers are used to minimise fibre release during dismantling and transportation and to bind fibres to material or room surfaces. Sprayers contain water and
suitable binding agents. Hand-held pump sprayers and airless sprayers are proven devices for this purpose, (p. 25)For large-scale work, especially with spray-

Use of a respirator requires the proper selection and fit of the respirator to the user, periodic training of the user by an industrial hygienist, as well as medical
examination to ascertain that the worker is fit to wear a respirator, and on-the-job supervision to ascertain that the respirator is being properly used. (3/8)
Airborne fibers are generated only if the fibers are free to be dislodged from the fiber-containing matrix, and most such matrices can be stabilized by several
methods, such as permeating a bonding material into the matrix. Such a technique will not only avoid exposure to the building's occupants, but will also reduce
the exposure to workers performing maintenance or modification tasks on or around the stabilized material. Other aspects include isolation of the asbestos
containing material by an impermeable shield and limited removal from places of constant access. (5/8)

monitoring. (2/11)
Engineering control: A considerable amount of dust control is achieved by moistening the asbestos which is being processed. This method may have to be augmented by exhaust
ventilation. (1/11) If dry asbestos must be handled, dust can be prevented from entering workroom air if operations are conducted under a total dust-tight
enclosure. In terms of exhaust ventilation, systems normally consist of a hood, ducting, a dust collector, and a fan. (2/11) Cleaning of contaminated work areas
should be done no less than daily

Engineering control:
The asbestos worker, in respiratory protection and full body "Tyvek" coveralls, physically entered the tent enclosure to perform removal tasks. Each tent
containment was maintained under negative air pressure with HEPA filtration units during asbestos removal. At the conclusion of asbestos removal and clean-up,
the interior walls and floor of the containment were vacuumed and wet wiped to remove any asbestos fiber contamination. The plastic enclosure was freed from
its supports, folded in on itself anddisposed of as asbestos waste,
inhalation
inhalable fibers
Personnel Protection Requirements. To protect the project workers, all work areas with airborne asbestos levels greater than 0.1 fibers/cc of air were designated
as asbestos control areas requiring protective clothing and medical surveillance. Respiratory protection was required for all work in asbestos control areas. The
standard for the type of respiratory protection was set at 10% of the OSHA standards that were current at the beginning of the project. That is, at the NIOSH
and OSHA proposed maximum allowable airborne asbestos levels forunprotected exposure to chrysotile (white) asbestos. Chrysotile asbestos is the most harmful
variety, as well as the type least likely to be found in normal asbestos type materials. Most asbestos removed under this project was in the form of amosite bricks
and spray-on fireproofing. In addition to the higher standard for respiratory protection, an action level was set at 50% of the maximum allowable airborne level for
each type respirator. At the action level, IT was required to either take necessary actions to reduce the airborne concentration or to increase the respiratoryprotection
by going to the type respirator with the next level of protection factor.Any work in an Asbestos Work Area required that workers wear The following protective
clothing and equipment:* Full-face air purifying respirators with high efficiency particulate filters or pressure demand air line respirators (Type C) were used when
asbestos was removed without glove bags. When glove bags were used, full face air purifying respirators with high efficiencyparticulate filters were employed.*
In addition to respiratory protection, all workers in asbestos control areas were dressed in full protective clothing. All workers wore surgical suits, cotton glove
liners, two pairs of gloves, disposable protective suits with hoods, neoprene boots and PVC-coated booties over the boots. All potential avenues for asbestos fiber
exposure, such as where booties overlap the disposable suit and around respirator face pieces, were sealed withtape.The protective clothing was disposable to
preclude problems in laundering the clothing. All workers entered and exited the asbestos work areas through air locks. Contaminated clothing was discarded as
asbestos waste during egress. All workers were then required to shower prior to entering locker areas containing their street clothing. Routine personnel and area
samples were taken for airborne asbestos levels both within the asbestos work area andin the surrounding areas.* Safety glasses, hard hats, and safety shoes were
worn by all workers, except that neither safety glass or hard hats were worn when respirators were used.
The full room containments were erected of Fasilon, a fire retardant, reinforced Herculite material, with frames consisting of either PVC pipe or wood with fire
retardant paint. Negative air pressure was maintained using Micro-Trap HEPA filtered portable ventilation systems. A minimum of six (6) total air changes per
hour was required, therefore, the number of units used depended upon the size of the area. Double chambered air locks with triple overlapping flaps were used as
access control points for the containments. Areas within the containments including the air lock, were designated as asbestos work areas (AWAs).

The initial action in this case of abatement was to seal the asbestos by spraying with a fire-retardant polymer coating. This original method didn't work, so the
decision was made to remove the asbestos completely. When the asbestos was removed, the ceiling was covered with fabric adhered with polymer coating to
encapsulate any remaining asbestos. (2/2)

Worker activity description: Access to the underside of the ceilings was by the use of mobile scaffold towers, obviously made rather awkward because of the subdivisions of the area into
manageable portions. Portionsof the ceiling not accessible with the towers were accessed by climbing over ductwork and judicious placing of Youngman boarding.
This second phase lasted approximately 6 months,even with a nightshift (p. 1-2)
Engineering control: adjacent areas are protected by sealing the work area with polyethylene sheeting, completely sealed and with airlock access and subject to smoke testing to ensure
airtightness. The work area is then subject to a lowering of air pressure, relative to surrounding areas, by means of filtered extractors. The purpose of this is to
eliminate any possibility of contaminating the adjacent areas with asbestos fibres, (p. 1) All adjacent areas were air-monitored by independent analysts a number
of times a day inorder to ensure that no leakage of asbestos fibres took place to occupied areas. The polyethylene sheeting dividing off areas was monitored
carefully at least once a day and repaired where necessary (p. 2)

Engineering control:
The project included the removal of acoustical plaster, thermalsystem insulation, and floor tile. The floor tile removal included removal ofthe tile mastic, the
adhesive which bonds the tile to the floor.Removal was performed by first pouring the solvent onto the floor surface from a 5-gallon container, agitating the
mastic-coated surface for approximately 10 minutes using heavy-bristle push brooms, collecting the mixture of solvent and dissolved mastic using a squeegee and
a shovel, and then placing this mixture into the empty 5-gallon containers. The 5-gallon containers were double-bagged for disposal as ACM.
The abatement crew consisted of 10 workers, 9 of whom worked inside the containment on the day of sampling.
During the removal of the mastic, workers inside containment wore coveralls and half-face air-purifying respirators (APRs), which were provided by the employer.
The coveralls were made of 100% spun-bonded polypropylene orTyvek (depending on which one the worker preferred)-. The respirators were equipped with
combination cartridges consisting of a high-efficiency particulate air (HEPA) filter coupled with an organic vapor cartridge. Workers also wore cotton gloves and
rubber boots. Eye protection was not worn by any of the workers.
Removal was performed under containment, with outside walls and doorways sealed off with polyethylene plastic and air filtration devices (AFDs) used to
maintain negative pressure in the containment area.

Worker activity description: Before the boards hardened, their surfaces were indented in the shape of the specific jewelry pieces to be soldered. In preaparation for new pieces, workers would
rub together two boards to obliterate the existing impressions, re-wet the boards' surfaces, and make fresh impressions. When asbestos powder was unavailable,
asbestos sheets were ground up instead, (p. 1)A secont recent report described a similar finding among Native American craftspeople who produce jewelry. They
use "pounding boards" made of asbestos to insulate worktables from the heat of brazing torches and molten metal. When silver slag accumulates on these boards,
they are clapped or rubbed together, resulting in substantial airborne asbestos exposure, (p. 1)

Removal of asbestos-based insulating laggingThere are three different methods that could be used for the removal of asbestos-based insulating lagging. The spray
method, using a manually controlled low pressure water spray, is suitable for ACM which is not covered by other materials that require prior removal, such as
paint or cladding. If the asbestos-based material is too thick whereby the dust cannot be controlled significantly by the spray method alone, a second method of
soaking involving total saturation can be used as an alternative. The third, dry method should only be considered in situation where the spray or soaking method
cannot be used. This method requires the insulating lagging to be isolated fully using plastic screening. The outer surface of insulation should be cleaned by
vacuum cleaners fitted with HEPA filters to remove loose ACM. Asbestos waste should not be allowed to accumulate in the work areas. Dampening of asbestos
waste to reduce dustiness before disposal is highly recommended. Dry sweeping must never be used to clean asbestos dust from any surface but rather, a vacuum
cleaning device with a HEPA filter should be used to minimize dust accumulation. When vacuum cleaning is impractical, the surface can be wiped clean simply
by using a wet rag and the floor can be cleaned by gently applying a water spray.Upon completion of the asbestos removal job, all the equipment including access
scaffolds and elevating platforms must be cleaned using water or a HEPA-filtered vacuum. Further, all asbestos waste and any polyethylene sheets used as barriers
should be disposed of in airtight containers,
inhalation, dermal, ingestion (after mucociliary clearance)
fibrous dust
Regular dust monitoring is required when asbestos work is in progress. If PEL is exceeded, the contactors must take all the measures mentioned above to reduce
generation of asbestos dust at the workplace.PPE must be used even when effective asbestos dust control can be achieved by other techniques. The workers must
be fully instructed in the use and maintenance of PPE.Water-proof full body protective clothing should be worn by persons engaged in removal of asbestos-based
insulation and in work areas where asbestos dust is likely to be generated.Such protective clothing should not have pockets. The clothing is best made of synthetic
fiber material that does not permit the penetration of asbestos fibers. Eye irritation can be prevented by wearing goggles. In addition, respirators with a HEPA
filter must be used whenever the work processes create asbestos dust during working of ACM. Workers must be taught to change the filters whenever they detect
an increase in breathing resistance, and fit testing should be conducted to ensure correct size of respirators.
A designated asbestos work area must be established before work begins. This area should be segregated and sealed to prevent the escape of asbestos dust to other
spaces, and access allowed only to authorized workers who are directly involved in the asbestos workWarning signs (part of the administrative control) should be
displayed at each asbestos work area, posted at high-human traffic areas, and at the entrance to the asbestos work area. Such signs should be written in simple
language to be comprehensible to all persons and they must remain posted until the work has been completedWithin the work area, all movable furniture should be
removed to avoid contamination with asbestos dust. Impervious polyethylene sheets also should be used to completely cover pieces of furniture and fittings that
cannot be removed from the work area. Air conditioning systems must be shut down as they can circulate asbestos dust to other parts of buildings.All exhaust air
from the asbestos work area must pass through a high efficiency particulate air (HEPA) filter before release into the environment.For decontamination purposes,
it is also important to set up proper washing and changing facilities for workers to wash themselves and to change into street clothing after the asbestos removal
work (Fig. 3). Three areas including a "clean area", a "shower area" and a "dirty area" have to be established in the worksite. During the asbestos removal work,
workers should only be allowed to enter and exit the worksite through the established washing and changing facilitiesPPE should be put on before entering the
asbestos work area.Efficient local exhaust systems should be installed whenever mechanical cutting, sawing or machining of soft asbestos insulating boards or
hard asbestos cement building boards takes place. Alternatively, water can be used as a dust suppressant for power cutting .For the removal of ACM from buildings,
wet methods should be used where feasible as this can prevent the asbestos fibers from becoming airborne. Wetting should be done before as well as continually
throughout the removal work. All debris should be collected and wrapped up immediately in impermeable polyethylene sheets while still wet, and all asbestos
waste must be affixed with proper warning labels before disposal

For all employees performing Class I work in regulated areas and for jobs without a negative exposure assessment, employers must provide full-facepiece
supplied-air respirators operated in pressure-demand mode and equipped with an auxiliary positive-pressure, self-contained breathing apparatus. Employers must
provide half-mask purifying respirators, other than disposable respirators, equipped with high efficiency filters for Class II and III asbestos jobs without a negative

materials. (21/38) IN addition, employers must provide protective clothing such as coveralls, gloves, and foot coverings. (22/38)
Areas where asbestos is handled must be marked off. (14/38) Local exhaust ventilation, enclosure of dust, vacuum cleaners with HEPA filters, wetting agents, and

EPA assumes a maximum exposure duration of eight hours per day (pg 81 of 168)
Frequency of release during container cleaning (provided in table 4.2 on pg 65 of 168) is equal to the lesser of N(cont_empty_site_yr) or TIME(working_days).
Similar values are provided for other operations.
Adhesive manufacturing facilities employed a total of 21,048 workers (pg 21 of 168). As per pg 107 of 168, It is assumed that 22 adhesive formulation workers
are potentially exposed to thechemical at each site. The total number of workers is 110.
No information on typical personal protective equipment (PPE) specific to adhesive formulation was found; however, a great deal of information is available
on typical PPE for the application and use of adhesive formulations. This information mainly focuses on minimizing exposure due to spray application or
VOC emissions. General assumptions can be made based on the known hazards of certain adhesive formulation processes: hot-melt adhesives are processed
at temperatures over 150°C and solution adhesives generally have VOC concerns. Chemical submissions recently submitted to EPA by adhesive chemical
manufacturers show that, at a minimum, all manufacturers recommended the use of gloves and safety glasses with side shields or goggles. Approximately half
of the submissions also recommended the use of some kind of ventilation and respirators if necessary. One submission for a hot-melt adhesive chemical also
specifically recommended the use of thermal gloves, (pg 79 of 168)

Parameter Data
Worker activity description: To determine expected exposures, a competent (Trained) person must perform an initial exposure assessment to assesses exposures immediately before or as the
operation begins. For Class I asbestos work, until employers document that employees will not be exposed in excess of the 8-hour TWA PEL and short-term
exposure limit STEL, employers must assume that employee exposures are above those limits. Class I asbestos work is the most potentially hazardous class of
asbestos jobs. This work involves the removal of asbestos-containing thermal system insulation and sprayed-on or troweled-on surfacing materials. Employers
must presume that thermal system insulation and surfacing material found in pre-1981 construction is ACM. That presumption, however, is rebuttable. If you
believe that the surfacing material or thermal system insulation is notACM, the OSHA standard specifies the means that you must use to rebut that presumption.
Thermal system insulation includes ACM applied to pipes, boilers, tanks, ducts, or other structural components to prevent heat loss or gain. Surfacing materials
include decorative plaster on ceilings and walls; acoustical materials on decking, walls, and ceilings; and fireproofing on structural members. Class II work
includes the removal of other types of ACM that are not thermal system insulation such as resilient flooring and roofing materials. Examples of Class II work
include removal of asbestos-containing floor or ceiling tiles, siding, roofing, or transite panels. Class III asbestos work includes repair and maintenance operations
where ACM or presumed ACM (PACM) are disturbed. Class IV work includes custodial activities where employees clean up asbestos-containing waste and debris
produced by construction, maintenance, or repair activities. This work involves cleaning dust-contaminated surfaces, vacuuming contaminated carpets, mopping
floors, and cleaning up ACM or PACM from thermal system insulation or surfacing material.Employers must determine employee exposure measurements from
breathing zone air samples representing the 8-hour TWA and 30-minute short-term exposures for each employee. Employers must take one or more samples
representing full-shift exposure to determine the 8-hour TWA exposure in each work area. To determine short-term employee exposures, you must take one or
more samples representing 30-minute exposures for the operations most likely to expose employees above the excursion limit in each work area.For Class I and II
jobs, employers must conduct monitoring daily that is representative of each employee working in a regulated area, unless you have produced a negative exposure
assessment for the entire operation and nothing has changed. When all employees use supplied-air respirators operated in positive-pressure mode, however, you
may discontinue daily monitoring. When employees perform Class I work using control methods not recommended in the standard, you must continue daily
monitoring even when employees use supplied-air respirators.
Exposure route: airborne fibers
Personal protective equipment: Employers must determine employee exposure measurements from breathing zone air samples representing the 8-hour TWA and 30-minute short-term exposures
for each employee. Employers must take one or more samples representing full-shift exposure to determine the 8-hour TWA exposure in each work area.
To determine short-term employee exposures, you must take one or more samples representing 30-minute exposures for the operations most likely to expose
employees above the excursion limit in each work area.For Class I and II jobs, employers must conduct monitoring daily that is representative of each employee
working in a regulated area, unless you have produced a negative exposure assessment for the entire operation and nothing has changed. When all employees use
supplied-air respirators operated in positive-pressure mode, however, you may discontinue daily monitoring. When employees perform Class I work using control
methods not recommended in the standard, you must continue daily monitoring even when employees use supplied-air respirators.Class I Employers must create
a decontamination area adjacent to and connected with the regulated area. Workers must enter and exit the regulated area through the decontamination area
Engineering control: Employers must ensure the following for all Class I jobs: Isolating heating, ventilating, and air-conditioning (HVAC) systems in regulated areas by sealing with
a double layer of 6 mil plastic or the equivalent. Placing impermeable drop cloths on surfaces beneath all removal activity. Covering and securing all objects
within the regulated area with impermeable drop cloths or plastic sheeting. Ventilating the regulated area to move the contaminated air away from the employee
breathing zone and toward a HEPA filtration or collection device for jobs without a negative exposure assessment or where exposure monitoring shows the PEL
is exceeded. In addition, employees performing Class I work must use one or more of the following control methods: Negative-pressure enclosure systems when
the configuration of the work area does not make it infeasible to erect the enclosure. Glove bag systems to remove ACM or PACM from piping. Negative-pressure
glove bag systems to remove asbestos or PACM from piping. Negative-pressure glove box systems to remove asbestos or ACM from pipe runs. Water spray
process systems to remove asbestos or PACM from cold-line piping if employees carrying out the process have completed a 40-hour training course on its use in
addition to training required for all employees performing Class I work. Small walk-in enclosure that accommodates no more than 2 people (mini-enclosure) if
the disturbance or removal can be completely contained by the enclosure.Article discusses requirements for Class II, III, and IV as well. Not reproduced here for

Exposure route: inhalation, ingestion (2/11)
Personal protective equipment: For any employee exposed to airborne concentrations of asbestos that exceed the PEL and/or EL, employer must provide at no cost to the employee, and require
the use of, protective clothing, such as coveralls or similar full body clothing, head coverings, gloves, and foot coverings. In addition, wherever the possibility of
eye irritation exists, face shields, vented goggles, or other appropriate protective equipment must be provided and worn. (4/11)
Engineering control: Engineering controls are the following: Employers are required to design, construct, install, and maintain local exhaust ventilation and dust collection systems and
provide a local exhaust ventilation system for all hand operated and power operated tools such as saws, scorers, abrasive wheels, and drills that produce or release
fibers of asbestos. They must handle, mix, apply, remove, cut, score, or work asbestos in a wet state to prevent employee exposure. They cannot remove cement,
mortar, coating, grout, plaster, or similar materials containing asbestos from bags, cartons, or other containers that are being shipped without wetting, enclosing,
or ventilating them. Do not sand floors containing asbestos. Do not use compressed air to remove asbestos or materials containing asbestos unless the compressed
air is used in conjunction with a ventilation system designed to capture the dust cloud created by tile compressed air. (4/11)
Comments: TimeWeighted Average (TWA) The employer shall ensure that no employee is exposed to an airborne concentration of asbestos in excess of 0.1 fiber per cubic
centimeter of [air] as averaged over an 8-hour TWA day.Excursion Limit (ELT) The employer shall ensure that no employee is exposed to an airborne concentration
of asbestos in excess of 1.0 fiber per cubic centimeter of air as averaged over a sampling period of 30 minutes.Except for brake and clutch repair where a "preferred"
control method is used, each employer who has a workplace or work operation covered by this standard must assess all asbestos operations for their potential to
generate airborne fibers. Where exposure may exceed the PEL, employee exposure measurements must be made from breathing zone air samples representing the
8hour TWA and 30minute EL for each employee.

RESPIRATORY PROTECTIONThe current OSHA standard allows the use of respiratoryprotection in three situations: (1) during the time necessary toinstall
engineering controls or implement work practices (2) inwork situations for which engineering controls and supplementalwork practice controls are insufficient to
reduce the exposuresto the proposed PEL; and (3) during an emergency, includingduring the period of the Emergency Temporary Standard. Therequired respirators,
primarily air-purifying respirators, as outlined in the proposed standard are currently available. Hence, technological feasibility is not a constraint.While it is
technologically feasible for all workers to wearrespirators, some practical constraints do exist. Some individualsare unable to wear an effectively fitted respirator
and function normally in the work environment. The proposed standard would require that such individuals be rotated to an available job not requiring the use of
a respirator, without experiencing any loss in seniority, status, or pay rate. It is not possible to determine, a priori, how many positions exist that do not require a
respirator, how many workers would be affected, or how such a requirement would affect existing contractual arrangements between employees and employers.
The proposed standard would allow for the use of disposable air-purifying respirators, provided that exposures do not exceed 10 times the PEL. Therefore, for all
applications where respirators would be required, air-purifying respirators would be used.

Engineering control: Receiving. Several methods of control and several newly developed packaging techniques would reduce asbestos exposure problems in the receiving areas.
These include: lined rail cars, palletized loading, wider cargo doors, pelletized or blocked asbestos fibers, and double-sealed bags. Use of fully containerized
shipments as opposed to shipment in bags would further reduce the exposures that occur when bags are damaged.If these control methods and proper work
practices are implemented, then OSHA expects that the levels of exposure could be maintained below 0.3 f/CC.Introduction. The exposures during the fiber
introduction could be adequately controlled if the bags or containers of asbestos are opened by machine. If the bags or containers are opened manually, a semi-
enclosed local exhaust ventilation system would be necessary to limit fiber emissions. Using these control methods and proper housekeeping, it is expected
that the exposure levels could be reduced to 0.4 f/cc.Processing. Fiber loss during mixing can be reduced by negative pressure, which is generally connected
to a local exhaust dust control system. Complete enclosure of the mixer is also a method that can be used to reduce exposures during this step. During the
cutting, sawing, and finishing steps, the installation of local exhaust and hooding could reduce exposures. Special tools, such as single-point cutting tools,
could reduce fiber emissions during particular activities.Shipbuilding and Ship RepairAsbestos exposures during shipbuilding are currently beingreduced through
the use of substitutes for asbestos products.The movement toward prefabrication in ships where adequatecontrols are available is also contributing to exposure
control.Ship repair, on the other hand, includes removal or refurbishingof old asbestos products o~ site (which is generally a narrow,small compartment). OSHA
expects that the control techniquesavailable for demolition activities could be applied whenasbestos products are removed. Since wet handling andventilation
procedures are not always practical due to theconfined space, OSHA expects respirators will be necessary tomeet reduced PELs. The refurbishing process in ship
repairgenerally uses prefabricated materials where possible. Somelimited finishing, however, may be necessary on site. It isexpected that the control methods
available for the finishingactivities in construction could be used to reduce exposuresduring ship repair or that respirators will be used.ConstructionEngineering
controls for construction activities are assumedto include local exhaust ventilation systems, substitution of anon-asbestos product, and modification or isolation
of a process.The installation of local exhaust ventilation systems on powertools or the use of mobile vacuum units could reduce the emissionof asbestos fibers
during cutting and finishing activities.Because some work sites are continually moving as the workprogresses, the development and use of portable equipment
wouldbe necessary. Prefabrication where possible may limit theexposures to asbestos; some fitting and finishing, however, maystill ~e necessary on site and thus
exposures would still occur.Wet cutting could also be used to reduce exposures, although thereduced productivity due to the messy work conditions and thedanger
of electrical shock may limit adoption of this option.Repair, maintenance, and demolition activities could use anamended water method when asbestos materials
are to be removed or altered. The wetting of the material significantly reduces the exposure levels by limiting the initial creation of dust and its subsequent
entrainment in the air.Complete discussion of Engineering controls are provide in section IV Technology Feasibility ( adobe pages 194-231)

PROTECTIVE EQUIPMENT* Respirator-OSHA requires one of three respirator groups to be used depending on the expected exposure level to asbestos fibers.
Any respirator used should be approved by NIOSH or the Mine Safety Health Administration (MSHA), carrying a written statement of approval on the product
data sheet or brochure. It is recommended that a respirator does not bond to the hood of a suit. The three general respirator groups and their recommended
use are as follows: 1. A reuseable or single use air purifying respirator whenairborne asbestos concentrations are between lx and lOx theOSHA ceiling or TWA
standard. These are the levels mostfrequently encountered at demolition and renovation worksites, according to OSHA. Note that cartridge approval for asbestos

ANSI standardZ87. 1-1979 requirements.'Hard Hat-Helmets must meet Al-SI standard Z89. 1-1 ~81 requirements.'Disposable Gloves-PVC gloves are recom-
mended by EPA if any handling of asbestos material is anticipated. • Disposable Suits-Recommended by EPA if any active demolition or renovation operations
are anticipated. Some type of protectiveclothing is required by OSHA if ceiling limits are exceeded. EPArecommends disposables made of DuPont Tyvek® or an
equivalentprotective material. The suit should include hooded coveralls withattached boot covers.
Negative AIR SYSTEMA negative pressure local air system may be used which containment barriers to reduce the pressure in an enclosed work area, protecting-
against large-scale fiber release in the event of a breach in the containment. This system may also reduce worker exposure by increasing room air turnover rate.
The system should be designed as follows:* Windows and doors are sealed as usual;* Locate exhaust units at a maximum distance from worker accessopenings,
allowing makeup air to traverse the work area as much as possible;* Size exhaust system to provide at least four air changes per hour; • Final filter must be a
High Efficiency Particulate Air (HEPA)filter, rated for at least 99.97 percent efficiency with 0.03 |jm DOPparticles (Military Standard No. 282-Certification No.
UL586).Prefilters (5 nm, 10 |jm, etc.) should be used to extend HEPA filterlife;* Exhaust system should run 24 hrs/day until job is complete, and at least 4 hours
after job completion; and* Replace prefilters and/or HEPA filter if change in pressure across exhaust system exceeds 1.0 in. H20

Asbestos abatement and removal
Respiratory protection should be worn until all these steps are completed. Change rooms, showers, and new protective clothing are required every time an
employee enters or leaves the asbestos worksite.
To reduce airborne asbestos, the material should be soaked with a water and wetting agent before attempting removal. Asbestos work areas must be sealed off from
the rest of the building, with the enclosed area put under negative pressure. Enclosure involves sealing the asbestos material behind airtight walls and ceilings,
with signs warning of the presence of the now-hidden hazard. But the fiber release continues behind the enclosure, and special precautions must be taken before
maintenance or renovation is undertaken in the area.Encapsulation is described as a temporary measure in which asbestos is sprayed with an EPA-approved,
paint-like material that bonds the fibers together in an elastic coating. Periodic reinspection is required to check for damage or deterioration, EPA advises.After
abatement is completed, the work area and plastic barrier should be damp mopped or vacuumed with HEPA filter equipment. Inspect all surfaces for dust. Look
for holes, voids, or cracks in enclosures or encapsulation. Check behind obstacles such as pipes and ducts. EPA recommends removing any plastic sheets covering
floors, walls, or other surfaces after this inspection is complete. Leave in place the sheets that separate the work area from the rest of the building.

During the work, the men wore permeable or impermeable clothing along with a powered or nonpowered filtering device including a full-face or half-face
mask. As of 1988, the regulations of the Finnish Council of State require that the employer provide dust repelling protective clothing and an efficient industrial
respirator for asbestos workers. Lightweight, disposable coveralls are the most common type of protective clothing used; they can be permeable, semipermeable,
or impermeable, (pg 241)
The asbestos removal was always carried out in an area that had been isolated with plastic sheeting in accordance with legislation The subjects put on the protective
clothing in the clean room of the decontamination unit before entering the work area After finishing the work, they took off their contaminated clothing inside the
equipment room of the plastic compartment, (pg 242)

the engine insufficiently covered by asbestos textiles. Again, workers manually added water to the cement powder and used this as a filler for uncovered surfaces.
(PDF pg 3)
In 1979-1980 the airborne standard for asbestos was 2 fibers/ml. Measurements at that time showed asbestos levels above this standard only in the filling process...
After the standard was reduced to 1 fiber/ml, levels above the standard were occasionally noted also in other work position (PDF pg 2)
A vehicle mechanic is employed in a professional (noncombat) capacity and is committed to five years of service—three years compulsory, two years as a regular.
Thereafter, he is either released from duty or continues his military career. The latter choice may involve continued exposure, if he remains in the same job, or
exposure may end with a job promotion (PDF pg 2)
The group involved in the filling process constituted only 1 % of the total workforce of the garages (PDF pg 2)

Parameter Data
Worker activity description: Carpets should be steam cleaned or vacuumed with a high efficiency particulate air (HEPA)-filtered vacuum cleaner.* Contaminated books and furniture should
be cleaned with HEPA-equipped vacuum cleaners, or dusted in the manner described below.* Dusting and mopping should be done with wet or damp cloths and
mops. These should be discarded in sealed plastic bags according to EPA regulations for asbestos removal and disposal. Workers should be encouraged to wear a
respirator as a precautionary measure.* When filters in a central air ventilation system are replaced, they should be treated as asbestos-contaminated waste. That is,
they should be sprayed with a light water mist before removal and then sealed in plastic bags for disposal.* Building occupants and maintenance workers should
be cautioned about further damaging the aSbestos-containing materials (for example, by hanging plants or mobiles from the ceiling, rewiring electrical circuits,
or installing new fixtures).* Maintenance people should be warned about disturbing suspended ceilings or other areas where fibers collect. They should also be
told not to patch or repair damaged material before assessment of alternative abatement techniques.REMOVAL* Removal of all types of asbestos except amosite
must be initiated only after the material is treated with a solution of water and a wetting agent to reduce fiber release. Some types of amosite-containing materials
will not adsorb either water or water amended with the wetting agent suggested by EPA (50% polyoxyethylene ester and 50% polyoxyethylene ether) in Part 1
of the initial guidance document (USEPA 1979). Wetting agents should be tested on the material for adsorption. If the material won't adsorb the wetting agent,
a dry removal will have to beundertaken using Type C respiratory protection for the workers. EPA must approve all dry removal operations.* Friable asbestos-
containing material must be disposed of in "leak-tight containers," typically 6 mil polyethylene bags. Bags frequently are placed in 55-gallon drums for additional
protection.* Once removal and disposal operations are finished, the need to apply a sealant on the exposed surface must be evaluated. This is also the time to decide
whether to reinsulate or resound proof with asbestos-free materials. In general, sealants are necessary where the underlying surfaces are porous (for example,
concrete blocks or slabs), since a few fibers usually remain after removal.ENCLOSUREEnclosure involves construction of airtight walls and ceilings around
surfaces coated with asbestos-containing materials. Enclosures should be constructed with impact-resistant materials. Since the asbestos-containing materials
will have to be removedwhen the building is remodeled or demolished, enclosure is only a temporary solution. On the other hand, carefully constructed, airtight
enclosures may reduce, if not eliminate, emission of fibers within the building for its remaining life.* Installing an enclosure will probably mean drilling and
anchoring into dry asbestos-covered surfaces. This releases dry asbestos fibers and could raise airborne asbestos concentrations to highly dangerous levels. Drills
equipped with HEPA vacuum filters will reduce fiber release.* Underlying structures must be able to support new walls and ceilings.* New construction material
should be impact-resistant and assembled to be airtight. Gypsum panels taped at the seams, tongue and groove boards, and boards with spline joints all qualify.
Suspended ceilings with lay-in panels do not. Joints between walls and ceilings should be caulked.* If lights are recessed into asbestos-containing material, they
must be removed carefully to minimize the release of fibers. Lights should be reinstalled in or beneath the new ceiling.* Plumbing lines and computer cables
may have to be relocated.* Building records must note the presence of asbestos behind the enclosure to prevent accidental fiber release during remodeling and
building demolition.ENCAPSULATIONEncapsulation involves spraying asbestos-containing material with a sealant. Ideally, this activity helps bind together the
asbestos fibers and other material components and offers some resistance to impact damage. As with enclosures, encapsulants are, at best, atemporary control
measure. The asbestos-containing materials will still have to be removed before building demolition. In addition, the presence of encapsulants can make wetting
and thus removing the material more difficult.Encapsulation can be used on granular, cementitious material-commonly known as acoustical plaster. A sealant
should penetrate the asbestos-containing material and adhere to the substrate (or form a tough skin over the material), withstand moderate impact, be flexible
and flame retardant, resist deterioration over time, and be nontoxic.Sealants should be applied with airless spray equipment. One recommended method is to
apply a light (mist) coat, then a full coat applied at a 90 degree angle to the direction of the first. Latex paint can also be applied by roller following the
application of the mist coat before it dries.SPECIAL OPERATIONS AND MAINTENANCE PROCEDURES AND PERIODIC REASSESSMENT. All custodial
and maintenance personnel should be instructed in special operations procedures. They should be cautioned about removing suspended ceiling panels, installing
lighting or plumbing fixtures, repairing air handling systems, or, in general, engaging in any activity that might damage asbestos-containing material or resuspend
fibers. Building occupants should be warned not to disturb the material by such acts as hanging plants fromasbestos-covered ceilings and damaging walls with
furniture.Periodic reassessments should focus on the condition of the asbestos-containing materials, changes in building use, and changes in occupants' activity
patterns. If reassessment suggests that fiber release has occurred or is likely, then other corrective actions should be formally evaluated.CONTROL MEASURES
FOR PIPE AND BOILER INSULATIONWhere damage to pipe covering or boiler lagging is limited, the most straightforward approach to abatement is repair.

Exposure route: inhalation
Physical form: inhalable fibers
Personal protective equipment: Worker protection depends on the strict use of NIOSH approved respirators. The OSHA standards specify the use of three different respirators, depending on the
expected concentration of fibers in the work area: a half-face mask with either a single-use or replaceable filter, a full-face mask with replaceable filter and a pump
to assist breathing, and a full-face mask with a self-contained or remote air supply. NIOSH now recommends that the first type of respirator not be used, because
it does not seal properly around the face, nor has it (or any other type) been tested for effectiveness specifically against asbestos fibers.* Supplied air (type "C")
units offer the most protection. Respirators are required for asbestos removal. They are highly recommended for the other control measures, since enclosure and
encapsulation activities may produce fiber levels as high as or higher than those created during asbestos removal.
Engineering control: proper work area containment is highly recommended for all abatement techniques except special operating and maintenance practices. Once abatement work
begins, all uninvolved persons should be kept out of the area. Containment typically means construction of barriers with 6 mil polyethylene plastic sheets joined
with folded seams, and with sealing tape at the seams and boundaries. Some contractors have experienced problems in securing plastic sheets to walls. Thinner
sheets or a better attachment system (for example, stapling and taping sheets to furring strips fastened to walls) may be required. (Figure 9 shows the construction
of a typical containment system.) Air locks and worker decontamination facilities with showers are recommended.* So, too, are negative air pressure systems,
a. Without adequate containment, increased exposure for buildingoccupants is likely. Abatement activities should be conducted during vacations or other times
when few people are in the building.

Worker activity description: Workers conducting preventative maintenance (low-speed spray-buffing, ultra high-speed burnishing, and wet-stripping) on asbestos-containing floor tiles, (pg 1
of 4)
Physical form: Floor tile contained approximately 5% chrysotile asbestos (pg 1 of 4)/
Area sampling data: For pre-existing floor care condition, larger (and statistically significant) increases in the TEM airborne asbestos concentrations were observed during wet-stripping
than during spray-buffing. None of the individual PCM concentrations exceeded the OS HA PEL of 0.1 f/cm3. Consequently, 8-hour time-weighted average (TWA)
concentrations based on these measured levels would not exceed the OSHA PEL. The highest individual PCM concentration (0.023 f/cm3) was measured during
wet-stripping, (pg 2 of 4) For the prepared floor studies, the mean relative increase in TEM airborne asbestos concentrations during low-speed spray-buffing tended
to decrease as the floor care condition improved; however, the differences between the three levels of floor care were not statistically significant (p = 0.1149). (pg
2 of 4) Larger (and statistically significant) increases in TEM airborne asbestos concentrations were observed during wet-stripping of floors in medium condition
than on floors in good condition. The relative increase in airborne asbestos concentrations was approximately 14 times greater, on average, during wet-stripping
of floors in medium condition than during wet stripping of floors in good condition. Therefore, although significant increases in airborne asbestos concentrations
were observed during wet-stripping of floors in both medium and good condition, the extra layer of sealant on floors in good condition appears to significantly
decrease the airborne asbestos levels that were generated by the activity. Overall, significantly larger increases (p = 0.0001) in airborne asbestos concentrations
were observed during wet-stripping than during low-speed spray-buffing. The relative increase in airborne asbestos concentrations was approximately 18 times
greater, on average, during wet-stripping than during low-speed spray- buffing, (pg 3 of 4) Similar increases in airborne TEM asbestos concentrations ewre
seen during ultra high speed burnishing and wet stripping of floors in both poor and good condition. No floor condition or maintenance procedure resulted in
significantly higher or lower increases in mean airborne asbestos concentration. Overall, ultra high-speed burnishing and wet-stripping resulted in an 11-fold
statistically significant increase, on average, in airborne asbestos concentration. None of the individual PCM concentrations exceeded the OSHA PEL of 0.1
f/cm3.
Engineering control: The results of this study suggest that multiple layers of sealant applied to the floor prior to the application of the floor finish can reduce the release of asbestos
fibers during polish removal, (pg 3 of 4)

of wetting agent slightly reduces the efficiency of resin-wool filters, and exposure to very fine mists of penetrant significantly reduces it. Both reduce the pressure

A well-fitted approved dust respirator or half mask type respirator are generally suitable to asbestos handling operations. When concentrations are high, more
sophisticated PPE is required like a HEPA respirator or air line breathing apparatus. Protective clothing should be made of material with low dust retention
properties, and should be vacuumed after the shift. (3/4)
Substitution of other materials for asbestos is one prevention strategy. (2/4) Processes and operations should be designed so that dust exposure is reduced to as
low as possible, like with wetting of ACM. Where it is not possible to prevent dust emissions, dust control methods should be employed like process enclosure
and exhaust ventilation. Dust collection filters should be properly disposed of. Dust collection system can be used also. (3/4) Impermeable bags should be used in

Release quantity:
Release or emission factors:
Release from sprayed-on asbestos, which has been used as insulation material, during disposal
The case study involved 6500kg (26m3) of sprayed-on asbestos (see Table 1); the emission factor was 7.4 x 10A-5kg/kg, and the constant for unit conversion was
3.0 x 10A13 f/kg (from the assumption of 30 f = lng by EPA). Also, provided that ratio of inappropriate disposal is 20%, as EPA assumed, the asbestos emission
was estimated to be 2.9 x 10A12 f.

Other anthropogenic sources of asbestos emissions besides mining are the crushing, screening, and milling of the ore, the processing of asbestos into products,
the use of asbestos-containing materials, and the transport and disposal of asbestos-containing wastes. [PDF PG. 174]Asbestos is released to water from a number
of sources, including erosion of natural deposits and waste piles, corrosion from asbestos-cement pipes, and disintegration of asbestos roofing materials with
subsequent transport via rainwater into cisterns, sewers, etc. (Millette et al. 1980). [PDF PG. 175]Soil may be contaminated with asbestos by the weathering of
natural asbestos deposits, or by land-based disposal of waste asbestos materials. While disposal of waste asbestos to landfills was a common practice in the past,
current regulations restrict this practice (see Chapters 5 and 8). [PDF PG. 175]

During construction, structural beams and the underside of the steel floor decks were sprayed with an asbestos-containing fireproofing. In the occupied spaces,
suspended ceilings form a plenum with the floor decks which is used to return office air to the heating, ventilating, and air-conditioning (HVAC) systems. This
directly exposes the friable asbestos-containing fireproofing in the plenum to the HVAC air, which is subsequently returned to the occupied areas,

Description of release source: Asbestos used in constructions will be released during a fire in the form of fibers; asbestos sheets crack, sometimes disintegrating explosively, and more likely so
if the sheet is worn or impregnated with resin. Chrysotile breaks down at 450-800 °C, and the amphiboles at 400-600 °C. Thus, the denaturing of asbestos during
fires may reduce exposure to asbestos fibers.

Data
Description of release source: Possible sources of particulate (asbestos) mining emissions include: drilling, blasting, loading broken rock, and transporting ore to the primary crusher or waste
to dumps. Subsequently, the ore is crushed which may lead to exposure from the following emission sources: unloading ore from the open pit, primary crushing,
screening, secondary crushing, conveying and stockpiling wet ore. In well-controlled mills, this is largely confined to the mill building and presents very little
emission to the air because the mill air is collected and, usually, ducted through some particulate matter control device. Asbestos cement - Possible emission
sources are: (a) the feeding of asbestos fibres into the mix; (b) blending the mix; and (c) cutting or machining end products. Emissions may range from negligible
to significant according to the dust control measures and technology.Emissions can also occur from sources other than processingoperations, such as the improper
handling and/or shipment of drymaterials containing asbestos and during the cutting or machiningof end-products. Asbestos paper and felt- The feed for paper
machines is prepared by mixing short chrysotile fibres with water and binders. Since papermaking is a wet process, little asbestos dust is generated during
manufacture. However, finishing operations, such as slitting and calendering, may be sources of dust emission. Asbestos textiles - Asbestos textiles are used in the
manufacture of fire-resistant garments, sealing materials, wicks, and thermal insulation, or as an intermediate product in brake linings, clutch facing, insulation,
and gaskets. Asbestos textile manufacturing is the dustiest of all asbestos-manufacturing processes, and dustemanating from this process is more difficult and
costly tocontrol. Use of products containing asbestos - Few data are available on fiber emissions during the use of products containing asbestos or other mineral
fibers. In most construction materials and consumer products, the fibers are firmly bound or encased in a solid matrix and are not expected to be released under
normal conditions, but may be emitted during manipulation or renovation of such materials or products (e.g., fiber levels measured by light microscopy in the
vicinity of such activities as removal of pipe lagging containing asbestos or the sanding of asbestos-containing drywall topping and spackling compounds may
approach or exceed current occupational exposure limits)

Data
Description of release source: There are two general forms of asbestos: friable and non-friable. Friable asbestos can be crumbled, pulverized or reduced to a powder by hand pressure when dry
and is the most dangerous form. Non-friable asbestos cannot easily be pulverized or reduced to a powder. This form of asbestos is damaged to the extent that
it can be crumbled or reduced to a powder by hand pressure must be handled and packaged like friable asbestos wastes. Resilient floor tile, roof felts, asphalt
tiles, asphalts, mastics and transite roofing shingles, siding and piping are considered non-friable forms of asbestos, unless they are or will be damaged during
demolition or renovation activities. In this context large demolitions are realised, frequently unnecessary and a big volume of wastes and dangerous dust is created.
These are mainly hazardous wastes that require an adequate disposal. (1/5)

Data
Description of release source: In Australia, raw chrysotile emissions/release may arise from the manufacture of CAF sheets for production of gaskets and the manufacture of 'non-sag' epoxy
resin.Raw chrysotile is used in Australia in the manufacture of CAF sheeting for gasket production (carried out by Richard Klinger Pty Ltd). Manufacturing of
the raw material is carried out in Perth, while gasket processing (e.g. cutting) is performed at both Perth and Melbourne factories. Richard Klinger estimates that
a maximum of 600 tonnes of CAF (510 tonnes of chrysotile) is produced in any one year. The volume of waste generated and sent to landfill is estimated at 35
tonnes per year, with an additional 30 tonnes recycled within the processing plant. Further, the plant's dust extraction system collects approximately 25 kg of
general dust per week, of which a fraction is asbestos fibre, all of which is then recycled through the system.

Parameter Data
Description of release source: Emissions occurring during process operations can be classified into the following categories:* Material loading emissions.* Heat-up losses.* Surface evaporation.*
Filling losses.Main emissions to the air are expected to come from VOCs such as solvents. VOCs may be emitted during loading operations, or if the contents of
mixers, dispersers or mills are exposed to the atmosphere. They may be emitted through the agitator shaft openings or around the edges of the vessel lids.Water
used in the manufacturing process of the coatings, remains in the coatings formulation.The only origin of releases to water are cleaning operations.Several emission
routes to soil are possible.* Deposition of dust particles in the workshop or outside the facility, if they are emitted via the exhaust system.* Adsorption of released
substances onto particles in the air and following deposition.* Land spreading of sludge from sewage treatment works handling discharges from industrial sources.*

silica-lung cancer mortality rates. The detailed assessment identified that a larger portion of the workforce at this site were exposed to Asbestos, the plan being
investigated stopped handling asbestos in 1977. Note this is a recreated assessment of earlier exposure (1920-1940 and 1951-1977) and may not be representative

Production, import, or use volume: Reported consumption of asbestos in the United States was 790 million pounds (359,000 metric tons) in 1980, 497 million pounds (226,000 metric tons) in 1984,
185 million pounds (84,000 metric tons) in 1987, 81 million pounds (35,000 metric tons) in 1991, 73 million pounds (33,000 metric tons) in 1994, and 46 million
pounds (21,000 metric tons) in 1997. By 1998 and 1999, U.S. consumption of asbestos had declined to 34.8 million pounds (15,800 metric tons) per year. [PDF
Pg. 166]
Life cycle description: The 1999 domestic consumption pattern was 61% for roofing products, 19% for gaskets, and 13% for friction products (automobile clutch, brake, and transmission
components). Roofing products, gaskets, and friction products will continue to be the only significant domestic markets for asbestos in the foreseeable future.
Only chrysotile is presently used for manufacturing in the United States (USGS 1999b). Ninety-four percent of chrysotile consumed was grade 7, a short (3 jUm)
fiber. Only 0.4% of the asbestos used were long fibers (6-9.5 jUm); these were mostly used in plastics (Chissick 1985; Jolicoeur et al. 1992; SRI 1982; USGS
1997, 1999b; U.S. Bureau of Mines 1992, 1994). [PDF Pg. 166]

Process description: In most cases, the mechanic removed most or all of the gaskets with his fingers or by prying them off with a screwdriver. Any residual gasket material left behind
was scraped off with the screwdriver or pulled off by hand. It generally took less than lmin for the mechanic to remove each gasket.
Chemical concentration: For cars containing asbestos gaskets, the content of asbestos in the exhaust system gaskets ranged from 9.5% to 80.1% for chrysotile as analyzed by XRD (Table
1). (P. 8/16)
Comments: The purpose of this study was to characterize personal and bystander exposures to asbestos during the removal of automobile exhaust systems (ca. 1945-1975)
containing asbestos gaskets. These data were used to estimate an 8-h time-weighted average (TWA) exposure for mechanics performing this type of automobile
repair work.Table 1. Summary of asbestos concentration (percent by weight) in automobile exhaust gaskets and mufflers.

Diaphragm, mercury cell, electrogalvanizing (EGL), and membrane gap cell (MGC) anodes and cathodes are manufactured in the fabrication area. The application
of proprietary precious metal coatings (to improve conductivity and prevent corrosion) and the repair of anodes and cathodes, takes place in the servicing and
finishing areas. Anodes constitute the largest number of structures handled by Electrode Corporation. Each type of anode has a different process line but follows
a similar process flow (pdf page 3)Incoming crates of anodes are opened and counted in the shipping and receiving department. These crates are unpacked and
evaluated in the diaphragm pre-coat area. Glanor anodes (a subset of diaphragm anodes) may become contaminated with asbestos during use, by the customer,
in chemical cells where an asbestos diaphragm is used to separate the anode and cathode, (pdf page 4)The anodes are cleaned prior to evaluation because of the
possibility of asbestos contamination. The anode washer is located in the pre-coat diaphragm area, a large open area, and is housed in a wooden shell. The washer
is separated from the shipping and receiving department by a 12-foot sheet of plastic, but the plastic sheeting does not reach theceiling. Workers open and unpack
crates of anodes, and then place the anodes in the anode washer. After washing, anodes requiring minor repairs are reworked prior to surface preparation (pdf page

Process description: 1) 80-inch Continuous Pickle Line Continuous pickling is a process for removing the oxide from the steel surface deposited during the hot rolling operation. The
oxide is removed by passing the steel through a bath of hot sulfuric acid. The steel is then given a water spray rinse and passed through a hot air dryer prior to
coiling with an oil coating to protect the surface.The 80-inch Pickle Line is 991 feet long and was designed to process product widths from 24 to 72 inches. The
entry section of the line is designed with two right angle conveyors feeding the coils eye horizontal to two processors. After the processors and the oscillating upcut
shears is a combination welder and flash trimmer. Next in line is the No. 1 looping pit which is 71 feet long by 13 feet wide by 16 1/2 feet deep. Following the
looping pit and tension units is a rolling mill type scale breaker. This mill is driven by two 750 horsepower, 690/875 revolutions per minute, 250 volt DC motors
through 4:1 reduction gears. Next in line is the No. 2 looping pit which is 59 feet long by 13 feet wide by 17 1/4 feet deep. Following the looping pit and master
pinch rolls is the pickling tank which is sectionalized into four sections. The first and fourth sections are 90 1/2 feet long and the second and third are 89 feet long.
All tanks are 7 feet 1 inch in depth. The width of all tanks is 9 feet 10 1/4 inches. The refractory lining is composed of 3 3/4 inch by 4 1/2 inch by 8 inch acid
proof bricks. The steel tanks are lined with 1/4 inch of rubber. Each tank has five 16 feet covers and three 5 feet 6 1/2 inch inspection covers. There are two strip
lifting mechanisms per acid tank.The rinse tank is 42 feet long by 9 feet 10 1/4 inches wide by 5 feet deep and is followed by the hot air dryers consisting of three
centrifugal blowers, each driven by a 75 horsepower, 3,600 revolutions per minute, 440 volt AC motor. The air is heated by three 4000 maximum air temperature
heat exchangers.Following two free loop looping pits the delivery section of the line consists of a side trimmer with scrap chopper and conveyor, exit shear,
upcoiler and tension winding reel. The maximum coil O.D. for the upcoiler and tension winding reel is 90 inches and the minimum coil I.D. for the upcoiler is 18
inches. For the tension winding reel, the coil I.D.s are 24 and 28 inches.2) 52 inch Five Stand Cold Reduction MillThe mill consists of five four-high stands spaced
on 14 feet centers, each housing weighing approximately 110 tons. The largest coil discharged from this mill can weigh approximately 90,000 pounds.Coils of
90 inch maximum O.D. are moved from the chain drive entry conveyor by a mandrel in the coil transfer unit which places them on the rolls of the coil positioner.
Solenoid valve controlled hydraulic power accomplishes this transfer.Two driven saddle rolls in the coil positioner rotate the coil in order to transport the outer
wrap through the coil opener into the straightener rolls. The straightener unit is removed from the pass line after straightening the head end of the strip and does
not contact the strip during coil run off. After threading the strip through the stands at speeds up to 750 feet per minute and wrapping the mandrel, the mill may
be accelerated to run speed up to a maximum of 6-000 feet per minute. Strip uniformity is insured by continuous dial readings of roll pressure, strip tension and
gauge. Backup roll pressure is measured by pressductor cell force gauges, which provide independent readings of force on front and back roll chocks. Tension is
measured with tensiometers, the force with which the tensiometer roll is deflected is measured on load cells and metered at the operators* stations. This mill is
equipped with automatic gauge control, and the finished gauge is monitored by means of an x-ray gauge.3) 80 Inch Five Stand Cold Reduction MillThe 80 inch
Five Stand Cold Reduction mill was designed to produce cold reduced low carbon high strength steel, and consists of five four-high stands spaced on 15 foot 6
inch centers, each housing weighing approximately 144 tons. Each stand is equipped with automatic work roll changing rigs.The 80 inch Five Stand Tandem Mill
will reach a maximum speed of 5,000 FPM with 23 inch diameter work rolls. While other members of the crew are on mill floor level, the roller, or operator, is
stationed in a glass enclosed, air conditioned, raised pulpit eight feet above the mill floor. The computer room is directly overhead of the operator's pulpit at a
20 foot level above the mill floor, and the electrical control room is on this same level.Strip uniformity is insured by the automatic gauge control system which
recognizes gauge deviation from a preset reference gauge and maintains the thickness of the strip delivered from the mill to within plus or minus 2 1/2 percent,
or .001 inch (whichever is least) of x-ray gauge measurement. Other features incorporated in the automatic gauge control are: programmed screw movement as
a function of mill speed change, programmed screw movement during strip tailout, and preset stand drive motor overspeed during strip threading.4) Electrolytic
Cleaning LineThe Electrolytic Cleaning Line is 309 feet long, operates at speeds up to 2,500 feet per minute and handles coils weighing up to 72,000 pounds
coming directly from the two Five Stand Cold Reduction Mills . Both cold rolled and tin plate coils are cleaned on this line.At the entry end of the line, the head
end of the strip is fed into a lap seam welder and welded to the tail of the previous coil to provide a continuous strip. There are no looping towers on this line and
the unit must stop running to charge and discharge coils. After welding, the strip passes through an electrolytic alkali cleaner, scrubber, hot rinser, and hot air dryer
to remove dirt, grease, oil, and residue from the strip to insure maximum cleanliness before entering the annealing furnace.The cleaned coil is discharged onto
a 45 foot conveyor. Discharged coils can be JeSg^eKJ&fiSsipflffl processing in either an eye horizontal or eye vertical position. Finished coils are provided

Data
Process description: [PDF Pg. 21] REMOVAL: The ACM is treated with a water and wetting agent solution to minimize fiber release. If the material will not absorb the wetting
agent, a dry removal using Type C respiratory protection is appropriate. EPA must approve all dry removal operations. Friable ACM must be disposed in leak
tight containers, typically 6 mil polyethylene bags. Bags can be placed in 55 gallon drums for additional protection. Bags and drums must be labeled as specified
by NESHAP or OSHA. Procedures for worker protection and decontamination must be strictly follow OSHA guidance. Airborne asbestos must be measured.
EPA work area containment procedures must be followed for a safe removal and disposal.[PDF Pg. 21] ENCAPSULATION:Encapsulation is the spaying of
ACM with a sealant. This may be a penetrant, which penetrates and hardens the asbestos material; or a bridging encapsulant, which covers the surface of the
material with a protective coating. Both types of sealants are applied using airless spray equipment at low pressure. This is done to reduce fiber release during
application.Encapsulation should use only granular, cementitious material. Material that is delaminated or deteriorated should not be encapsulated. The material
will be pulled down by the additional weight if its de laminated. Deteriorated ACM may be blown off by sealant application. EPA has evaluated over 100
sealants, using five criteria; impact resistance, flame spread, smoke generation, toxic gas release during combustion, and adhesive strength. This study data
is useful in selecting a sealant, but the sealant should be tested on site over several days to determine its effectiveness. The type of sealant and the type of
material and substrate encapsulated should be recorded. This information in needed to avoid asbestos fiber release during later remodeling or demolition. [PDF
Pg. 22] ENCLOSURE:Enclosure involves the construction of airtight walls and ceilings around the ACM. The purpose is install a barrier between the ACM
and the building environment. Corrugated metal or PVC installed around ACM insulated piping is an example of an enclosure. A combination of encapsulation
and enclosure are often required for maximum protection. The following are recommendations for constructing enclosures.Drills equipped with HEPA (High
Efficiency Particulate Air) filtered vacuums should be used during installation to reduce fiber release.lt must be ensured that underlying structures are capable of
supporting new walls and ceilings. New construction materials should be impact resistant and assembled to be airtight. Gypsum panels taped at the seams, tongue
and groove boards, and boards with spline joints are all acceptable, suspended ceiling with lay-in panels should not be used. All joints between walls and ceilings
should be caulked.Lights recessed in ACM should be carefully removed to minimize fiber release. Plumbing lines, telephone cables, and computer cables should
be relocated as necessary.Building records should be updated to note the presence of asbestos behind the enclosure to prevent accidental fiber release. These
documents should be reviewed before beginning remolding or demolition. Signs noting that ACM is behind the enclosure should be posted. A part of an O&M
program is the documentation of ACM in a building.

Process description: In the process room, chemical weighing and mixing is accomplished. The pigment operator measures the required quantities of pigments (from bulk materials) at
a booth which has slot ventilation. The pigment is placed in a plastic bag and dropped into the hopper car. The hopper proceeds to the first of two scales, both of
which have canopy exhaust ventilation, where the resin scale operator places a bag of asbestos onto a horizontal chute, splits it in both directions and pushes the
bag into the hopper. Two additional chemicals are automatically metered and conveyed to the hopper. The hopper car is transferred to the second scale operator
who loads the hopper with scrap tile. The hopper car is then conveyed to the Banbury mixer where the operator dumps the hopper load into one of two mixers inlet
chute which are alternately charged and dumped onto a conveyor belt below. In addition, the mixer operator triggers a switch which dumps the other chemicals
(plasticizer, limestone, polyvinyl chloride pellets, scrap tiles, and water) into the inlet chute. The materials are mixed for the prescribed time; after which, the load
is released through the discharge chute. The mixture, when released, is hot (160-300°F) due to frictional mixing. The mixture is subsequently conveyed to the mil
Is to be gauged, colored, waxed, polished, cut and packed. The mottle, once gauged, is crushed and added to the vinyl asbestos tile. (5/24)

Because of the ages of the buildings involved, the extent of surface deterioration of roofing usually was severe: each sheet presented a loose surface layer enriched
in asbestos compared with the original product. Asbestos concentrations during building demolition weremeasured only for the period of sheet handling.
Four samples of asbestos-cement roof sheets were taken. Fiber contents were 32%, 25%, 22%, and 24%. (4/10) Dust concentrations accumulated during
demolition were 0.006-3.7% chrysotile and 0.003-0.9% amosite. (8/10)

Process description:
Chemical concentration:
A series of work trials were carried out at several sites where 30 to 40 year old AC clad buildings were re-roofed or demolished. Roofreplacement was carried out
by two to six men working on top of the roof who repetitively unfastened and removed small sections (20 to 40 m2) of old AC roofing and replaced it with steel
roofing. Sheets were removed whole and were carried across the roof to be stacked or dropped into a bin at ground level. Trials were conducted for 2 to 6 hours
during which 50 to 100 m2 of roofing was replaced. The buildings that were demolished were several large (90 m x 36 m) warehouses with corrugated AC roofing
and flat AC sheet wall cladding. Most of these were demolished by removal of whole sheets from the structure by men confined to elevated platforms beneath
the sheeting. In comparison to roof replacement, work conditions during demolition were more confined, involved closer handling of sheeting and were visibly
more dusty, particularly as sheets were stacked on the platforms. Repetitive trials over shorter periods(30 to 60 minutes) were generally employed for these cases.
In sometrials comparative measurements were made after sheeting had been wet with water or sealed on its weathered surface with an acrylic emulsion (28% by
weight solids applied at 0.3L/m2).
It is seen that the layer is enriched in asbestos fibre relative to the original product (usually 12 to 15 % w/w asbestos).

Process description: [PDF Pg. 7-8]Several removal phases had already been completed before this survey was made. One phase had involved the removal of pipe lagging and
contaminated soil from the crawl spaces beneath the hospital. This was described as a very difficult job.A previous phase had involved the removal of asbestos
from hot boilers and pipes. This condition was necessary, since these hot systems needed to remain in operation during the removal period. Removal activities
were interrupted between phases so that completed areas could be renovated and reoccupied before a new phase began. At the time of this visit, a new removal
phase had just commenced. Workers, on ladders, were removing pipe lagging from above a false ceiling. They were also cleaning corridor ceiling pans which
contained fiber glass insulation batting. Wet removal methods were used, including spraying of pipe lagging and cleaning of surfaces with wet rage. HEPA
cleaning was also used.

Chemical concentration: Table 6-4 summarizes the expected surface soil concentrations at properties in OU4 and OU7 where soil removals have and have not been completed. As shown,
for properties where a soil removal has been completed (Category #1), surface soils that remain "post-removal" should be a mixture of Bin A (non-detect for
LA) and topsoil fill materials (which are also non-detect for LA). For properties where no soil removal had been deemed necessary prior to 2014 (Category #2),
soil concentrations could be as high as Bin B2 across the total exposure area (Bin C concentrations would have triggered a soil removal). As discussed above,
properties where yard soil concentrations are Bin B1 or Bin B2 have the potential to result in RME non-cancer HQs greater than 1, depending upon their spatial
extent. Therefore, there may be properties in OU4 and OU7 where soil removal actions have not yet been completed that have the potential to result in elevated
LA exposures if soils are disturbed. Beginning in 2014, the soil removal triggers were modified to conduct soil removals at properties with Bin B1 (depending
upon their spatial extent) and Bin B2 (regardless of spatial extent) soil concentrations. Specifics on these modified soil triggers are presented in Amendment B
(CDM Smith 2014c). Bin B1 (trace) surface soils are allowed to remain in place in SUAs and CUAs, provided that their spatial extent is less than 25% of the
total exposure area. This decision was based on the finding that, if 75% or more of the total exposures area is Bin A and the remainder is Bin Bl, the estimated
area-wide RME non-cancer HQ will be about 0.6. For properties where soil removal is deemed necessary, but has not been performed (Category #3), the potential
exposures and risks from soil disturbance activities will depend upon the nature and extent of the LA concentrations in soil present at the property. However, it is
possible that Bin C concentrations may be present. Properties where yard soil concentrations are Bin C have the potential to result in area-wide RME non-cancer
HQs greater than 1, even if their spatial extent is small. For properties where no soil information is available (Category #4), potential exposures and risks from
soil disturbance activities cannot be determined, (pg 6-11)

Process description:
The method uses a garden-type tank sprayer of 2 to 3 gallons capacity which is equipped with a pointed wand for insertion under asbestos pipe covering. The
spray nozzle of the hand-operated sprayer is replaced with a 3' x 5/ 16" stainless steel or brass tube which has small holes drilled intermittently along the length.
The tubing must be stiff and strong to withstand the stress of shoving it under pipe covering. A tip is brazed onto one end and ground to a point; an adaptor is
brazed to the other end which is then fitted to the actuating valve of the sprayer. An industrial non-foaming wetting agent, such as Wyandotte's Pluronic L-62 LF,
is mixed with water in the tank ( 1 / 2 oz. in one gallon of water). The wetting agent is essential to ensure complete absorption of water by the insulation.The
pointed end of the wand/ tube is then inserted its full length under the fabric covering of the insulation through a small hole. The solution in the sprayer is pumped
through the wand to soak the insulation along the 3' section. One gallon or less will usually saturate a three foot section of insulation with one insertion.

Parameter Data
Process description: Waste containers within the non-thermal treatment areas are managed in a manner to prevent container rupture or leakage and to minimize exposure of AMWTP
facility personnel. Operating standards used in conducting non-thermal treatment activities include:- Wastes slated for direct supercompaction are first identified by
item description codes, generator-supplied information, and real-time radiography (RTR) examination. Other wastes for supercompaction and macroencapsulation
are sorted, segregated, and size reduced in the pretreatment lines prior to supercompaction and/or macroencapsulation. Waste characterization information is
reviewed prior to processing in the nonthermal treatment units to ensure that only compatible wastes are treated.-All non-thermal treatment activities are performed
by operating personnel trained to safely conduct the treatment and to respond to emergency incidents.-All treatment activities are conducted with the knowledge
of a supervisor and according to specific treatment procedures.-Containers enter the non-thermal treatment areas through a combination of elevators, conveyors,
and airlocks. Containers are lidded during compaction and after loading puck drums with waste and grout. Barcode readers throughout the facility verify waste
container locations and destinations.- The presence of liquids in supercompaction feed drums is minimized by prior RTR screening and liquid removalin the
pretreatment lines.-Special case waste is managed within the single case waste glovebox on a case-by-case basis, typically in smallquantities and in a timely
manner to reduce waste accumulation.-No reactive (Hazardous Waste Number [HWN] D003) wastes are processed in the non-thermal treatment units. Waste
streams potentially containing ignitable (HWN D001) wastes are processed in a manner to minimize reactions or fires (e.g., campaigning incompatible waste
separately, using only low-sparking tools in thetreatment areas when processing potentially ignitable wastes).-The ventilation air is ultimately fed to banks of high
efficiency particulate air (HEPA) filters and carbon filters prior to exhausting through the facility stack. The exhaust from the special case waste (SCW) glovebox
is also fed through local carbon absorption units before exiting the facility stack.-Secondary waste streams generated in the treatment areas are treated within
the facility.SupercompactorThe 55-gallon direct-feed waste drums or 55-gallon transfer containers from the pretreatment lines are routed to the supercompactor
via the central conveyor system. Only waste drums whose waste to waste compatibility assessments show no incompatibilities are compacted in series. Barcode
readers and the data management system (DMS)/waste tracking system (WTS) identify and control drums of incompatible waste from entering the compaction
gloveboxes until the gloveboxes have been emptied, visually inspected, and cleaned (if required). To maximize the size reduction process, the data management
system incorporates an optimization algorithm that automates the waste drum selectionfor puck drum filling to achieve maximum packing densities. The data
management system optimizes puck filling based on fissile content, weight, or puck height. Automatic control sequences to retrieve, deliver, compact, and deposit
the waste drum/puck into the puck drum are initiated from the central control room.At the supercompaction area interface point, a barcode reader identifies the
waste drums before they are transferred, viaroller conveyor, through an airlock and into the supercompactor infeed glovebox. There are two stations within the
infeed glovebox: the drum lidding station and the drum lid crimping/drum piercing station. A roller conveyor is used to move the waste drum from the glovebox
entrance to the lidding position. Waste transfer containers from the pretreatment lines require lidding before compaction, since they remain open during transfer
through Zone 3 process areas. At the lidding station, a drum handling mechanism is used to center and secure the open waste drum during thelidding process. Lids
are automatically fed from outside of the containment into the glovebox using a special seal arrangement. The feeder device fits the lid directly onto the top of the
drum.The drum handling mechanism transfers the lidded drum onto the compaction trolley at the drum lid crimping/drum piercing station, where a crimping head
is lowered to fasten the lid into position, while at the same time piercing the drum to prevent over pressurization during compaction. After supercompactor feed
drums have been lidded, crimped, and pierced, the drum handler arms are opened leaving the drum centrally located on the compaction trolley. The trolley moves
the drum into the supercompactor glovebox to a position beneath the supercompactor.With the drum and trolley in position, the mold/bolster is lowered around
the drum and engaged onto the trolley. The lower press plate of the supercompactor is mounted on the top of the trolley and acts as a guide for the mold, which
controls the puck diameter during the compaction cycle. The compaction process proceeds in two phases. First, the main ram is lowered, initially powered by a
low-force ram, which forces the air out of the top section of the drum at a preset pressure. After the first compaction phase, high-pressure fluid is supplied to the
main high-force compaction ram and is maintained at a higher pressure for a set period of time (1 to 5 minutes, depending on the waste being compacted). Preset
compaction pressures are used to control the compaction process. Both rams are fed from a hydraulic power pack situated outside the glovebox. The resultant
force reduces the puck height (on average) to one fifth of the original drum height. On completion of the compaction cycle the mold and ram are raised, and the
compaction trolley transfers the puck to the post compaction glovebox.All drums destined for direct supercompaction undergo RTR analysis at the waste storage
facility (WSF) Type 1 module for the presence of liquids or prohibited waste. Those drums potentially containing liquid waste are transferred to the drum line to
remove the liquid prior to compaction. FrequBft§61et2ll3)f'£qli6$$om drums during compaction are not expected. When liquids are released, they are handled

The asbestos, usually 1-3 inches in thickness, was applied either as a slurry, spread onto the girders to create a fibrous mat, or, more frequently, as a mixture of
fibers and binders blown under pressure from large hoses onto the superstructure. As this phase of the construction was under way, members of other building
trades worked on the partially completed lower floors.

Data
Process description: AAK uses chrysotile in two high-pressure electrolysis units for hydrogen production. Chrysotile is used in the gaskets and in the diaphragms in these units.At Dow
the process consists of two subprocesses i.e., use of diaphragms containing chrysotile (exposure scenario entitled Use in diaphragm cells) and use of chrysotile
fibres to maintain the diaphragms during their use in the process (Exposure scenario entitled Use as reconditioning agent).The diaphragms containing chrysotile
are embedded in cells such that both the diaphragms and the chrysotile in them are unaccessible to employees. Furthermore, inside the diaphragms, the chrysotile
fibres are embedded into a plastic matrix and operated as a wet process, which prevents chrysotile fibre release. The waste water and potential fibre releases in it
are treated separately. The potential points of exposure are managed by the process design and where needed (e.g. maintenance activities), by the use of personal
protective equipment (PPE). Bulk chrysotile is brought to the site as dry fibres. For transportation Dow uses specially designed Dow System Containers (DSC) to
ensure safe process (in the dossier see Annex 2.1.). As exposure to dry fibres is considered dangerous, all handling of the dry chrysotile fibres is fully automated.
The dry fibres are mixed with brine in an automated process to produce slurry, which is used to maintain diaphragms in cells while in operation. The process
design i.e., automation and the use of robots, minimises the exposure. Furthermore, PPE is used where needed e.g. during any periodic cleaning or maintenance
tasks. When diaphragms are worn out and need to be replaced, the chrysotile is washed out from the cells and the waste is heat-treated in a special oven, such that
the fibre structures are destroyed. Dow reports the resulting waste to be non-hazardous and usable as filler in construction.

Process description:
Unloading was done with a palletized load using a fork lift. For laying pipes in trenches, one worker remained in the trench and another worked topside. The
topside worker attached a clamp to the pipe, lubricated the end, then got into the trench to help guide it into place for coupling. Cutting was done with manual
saws, snap cutting equipment, and abrasive discs. For hole cutting, 5/8 inch holes were drilled in a circulate pattern of about 6 inches in diameter, after which
the central portion was knocked out with a hammer and the rough edges smoothed with a rasp. For removal of coupling, a hammer and chisel were used to make
troughs in the coupling. Then, a crowbar was used to separate the coupling. (10/44)

Process description:
Chemical concentration:
Each cutter sits at a bench behind, a spinning polishing wheel. Regularly shaped diamonds can be clamped into holders with long arms and either manually placed
against the spinning wheel, or held in a vise-like unit. Since fancy, irregularly shaped diamonds will not set in this holder, the cutters make a sticky paste to hold
the stone. A cutter will tear off a piece of asbestos paper-approximately a square inch-from a roll and mix it with sugar and water in a jar. The cutter will remove
this mixture as needed. (2/6)
Analysis of a bulk sample of the material used for making the paste confirmed it was asbestos, containing an estimated 50 to 70% chrysotile. (5/6)

Process description: NIOSH Recommendation [PDF Pg. 9]As only a small amount of asbestos is involved, NIOSH suggests the following procedure be used during repair of the pipe
covering: A plastic drop-cloth be laid on the floor underneath the area to be repaired. One person perform the clean-up operation wearing a respirator approved
for protection against asbestos particles. The fibrous glass batting carefully be wrapped around the damaged pipe and the duct tape carefully be applied. The
drop-cloth . (along with any asbestos which may have dropped from the pipe) be thrown away after the repair work is finished. The person who performs the
repair work should shower as soon as possible. Grinding, sanding or polishing of petrified wood slabs is an infrequent occurrence at this site, consideration should
be given to the use of a respirator approved -for protection against dusts while these operations take place, since the dust generated contains a large percentage of
quartz and some lead. As the silica dust which contaminates the rug may act as a secondary source of exposure, the rug should be vacuumed thoroughly. The silica
particles are relatively large, and should easily be contained by the average "bag" type of vacuum cleaner. Since the contamination of the floor covering will be an
on-going occurrence, consideration should be given to replacing the rug with a flooring such as tile, which is easier to clean.
Chemical concentration: The pipe insulation material was determined to be approximately 25% asbestos. [PDF Pg. 7]

Data
Process description: The asbestos was removed in three types of containments,full room, tent type, and glove bag. The full room containments were erected of Fasilon, a fire retardant,
reinforced Herculite material, with frames consisting of either PVC pipe or wood with fire retardant paint. Negative air pressure was maintained using Micro-Trap
HEPA filtered portable ventilation systems. A minimum of six (6) total air changes per hour was required, therefore, the number of units used depended upon the
size of the area. Double chambered air locks with triple overlapping flaps were used as access control points for the containments. Areas within the containments
including the air lock, were designated as asbestos work areas (AWAs).Tent containments were utilized inside of rooms or chambers, around vessels and pipes to
prevent asbestos contamination of adjacent areas. Tent containments consisted of 6 mil Fasilon sheeting making up the walls, floors, and ceiling of the enclosure.
Wood frames or existing structural members were utilized for support of the containment. All tent containments were constructed with double air-lock entry.Two
(2) different types of glove bag containments were used. The first type was a single use type which was used for valves, joints3 and areas which, were hard
to access. The second type used was a Canadian glove bag with a zip lock closure to allow for movement along straight runs of pipe without breaching the
containment. The asbestos work area for a glove bag was defined as the area inside of the glove bag.Less water was used to wet the surface of the material being
removed due to the potential of radiological contamination and the cost to process the wastewater. Alternatively a wetting agent was used with an encapsulant to
help reduce airborne asbestos levels. The wetting agent used for all asbestos removal was BWE-5000. This wetting agent is a poly based surfactant manufactured
by Better Working Environment, Inc., of Las Vegas. BWE-3000, an encapsulant from the same company, was used when asbestos removal was terminated to
capture asbestos fibers and dry them to a hard plastic finish.

Process description: The asbestos materials are commonly sprayed with water that contains a wetting agent to enhance the penetration. Dry removal is done on select cases only, such
as computer rooms and electrical rooms. The friable asbestos is removed by scraping the material from the substrate with the appropriate mechanical equipment.
When removed, the material is packed into properly labeled, 6-mil-thick (minimum), sealable plastic bags prior to starting the next section of work. The thickness
and density of lagging materials in pipe insulation seldom allows removal in an entirely wet state. The covering over the pipe insulation is cut along the top seam
to allow the asbestos insulation to be wetted before removal. Once the asbestos has been wetted, the fasteners are cut and the insulation is removed immediately
and placed in polyethylene bags. (2/2)

Parameter Data
Process description: Even before any asbestos could be stripped, a huge containment structure was built around each heat exchanger, providing a controlled environment within which
to carry out the physically demanding work. Powerclad sheeting was used to protect the asbestos from the environment and provide some element of containment
if any of the material fell to the ground.The stripping process takes place within an airtight structure that is built within the contained housing. At one end of the
airtight structure is an airlock, and at the other is a negative pressure unit which is used to remove any residual fibres via a Hepa filter while stripping is being
carried out. But before any work is carried out, a smoke test is undertaken to ensure that the structure is airtight. Once this is done, the asbestos is injected with a
substance that helps bind it, so that it comes off in lumps rather than fibres. The job is done by workers kitted out in full respiratory equipment. First, a bulk strip
from top to bottom of the heat exchanger is carried out, with as much as 150 tonnes of asbestos being removed within 10 days. Then a fine clean is carried out.
Every part of the heat exchanger is taken back to bare metal using manual methods and a dustless grit blasting machine known as a quill falcon. This is a slow
process, taking up to six weeks, as it often involves cleaning around hard-to-get-at fittings such as welds and pipes. Then the structure is washed down, where the
odd fibres are picked up, and there is a visual inspection by an independent firm. If the work is passed, a stage-two clearance is then issued and the job progresses.
Then air samples are run for a set number of hours, with the filter papers taken away for assessment. If the fibres on the filters are below acceptable levels, then
a stage-three clearance is awarded. The containment tenting is then removed, and a final check is carried out, before the structure can be deemed to be asbestos
free. [PDF Pg. 4]

Parameter Data
Process description: The Tarrallton school project involved removal of sprayed on ceilings. It was divided into three areas/phases to provide better containment area air flow patterns
for ventilation controls. The removal in Phase 2 had been complicated by unexpected difficulty in wetting and removing some portions of the asbestos which had
been painted over, effectively sealing the asbestos from water. The first two removal phases had been completed and the third phase containment barriers were
being set up at the time of our walk-through on the 26th. Workers hanging polyethylene were wearing high-efficiency half-face respirators as a precaution. The
third phase removal activity was scheduled to begin the morning of the 27th. It was delayed briefly while lighting fixtures were removed and bagged. Two teams
of two men on mobile scaffolding began removal in one classroom as soon as the light fixtures wereremoved. Wetting was done in stages ahead of the removal
work. The sprayed on ceiling material came off in cakes and appeared to be well controlled. This decontamination facility was a three compartment walk-through
shower/decontamination unit, constructed from two by four framing and opaque plastic. This initial removal work was performed in RACAL powered air purifying
respirators (PAPR) with full-face masks. The workers woredisposable contamination control garments. The NIOSH investigator who entered the site borrowed a
PAPR from the contractor. A Virginia Bureau of Occupational Health (BOH) inspector visited the site and monitored while NIOSHwas there. It is BOH practice
to try to visit each site on initial startup and again during cleanup.. (P. 6/11)

pipe, folded over the pipe lagging, the edges were rolled together and stapled to the top of the lagging forming a cylinder or envelope enclosing the lagging Duct
tape was used to seal the longitudinal seam The envelope was made much larger than the diameter of the lagging to facilitate working inside it the first day, but
on subsequent days it was constructed to be merely a loose fit around the lagging The surface of the lagging was misted with amended water (water containing
wetting agents, penetrants, and/or other agents to enhance the wetting-down process) to control surface dust before enclosing it in the poly. Removal:During the
first day the glove bags were hung at widely separated, predetermined intervals as part of an extended envelope. The lagging was removed In the envelope, then
transferred to the bags through the poly envelope Workers reached through openings they cut in the top of the envelope rather than using the gloves In the bags
to accomplish the removal and transfer of the lagging to the bags The glove bag was used as a receptacle rather than as a glove bag The tools for cutting metal
bands and lagging were inserted, operated, and transferred between hags through breaches in the enclosure. The lagging was wetted as it was removed from the
pipe Water sprayers (hand-pumped garden sprayers having a 2- to 3-gallon capacity) fitted with 30" hoses; were elevated to the working level, and were often
hung from the pipes This technique required workers on ladders and platforms to climb down periodically to fill the sprayer with amended water and pump up the
pressure The pipe was washed with water and rags after the lagging was removed It appeared that glove bag removal was a new technique for this crew and that
they had little previous experience with it Therefore, on the second day workers were lnstt"Ucted by the NIOSH survey team on improved procedures to enclose
and remove the lagging within the glove bags and to transfer contaminated tools to the next glove bag, i. e. , the tools for cutting metal bands and lagging were
placed inside the glove bag and the bag was hung from the pipe Bags were taped to form a seal along the length of pipe and then the bag ends (sleeves) were taped
to the poly-jacketed pipe The lagging was wetted as it was removed from the pipe Contaminated tools were transferred to new bags from the previously used bag,
inside an inverted glove which was tied closed and cut off workers were cautioned of the need for increased wetting It was suggested that by using longer hoses,
the pressure vessels could remain on the floor and be serviced by a worker on the floor level, thereby eliminating the need for frequent climbs from ladders and
scaffolds to accomplish this task Decontamination:The spilled material was removed from the floor with a portable REPA vacuum cleaner After the work was
finished in an area, the poly was removed from the floor and the floor was wet mopped Bags of waste were removed from the enclosure prior to post-removal air
sampling. The poly seals on windows, vents, and doors were kept in place to minimize the interaction with the surrounding areas and activities.

etc. Surfaces not involved in the removal are covered and sealed with plastic sheeting (usually polyethylene, commonly called "poly") and the lighting fixtures
are removed Two entrance and egress contamination control facilities are established one with showers and change rooms for personnel and the other for waste
material handling.Removal-The asbestos-containing materials are wetted (saturated, if possible) as they are removed from the structures they cover, then the wet
debris is collected and removed from the area, Work is accomplished in small increments to avoid accumulation of waste. In order to contain the fibers and
to prevent contaminating the outside air, the containment enclosure is maintained undernegative pressure and is e:lmausted outside the building through HEPA
filters. Air should be exhausted in sufficient quantity and with consideration of the flow patterns within the enclosure to optimize the benefits of dilution air in
reducing fiber concentration within the enclosure. The EPA recommends four air changes per hour, however, some contractors use twlc- this amount Whenlarge
air volumes cannot be exhausted, a portion of the air cleaning may be performed by recirculating it through HEPA filters inside the work area Sometimes local
pickup at the point of release is used Work should begin at the point furthest from the exhaust and proceed toward the exhaust The workers inside the containment
must wear appropriate, approved respiratory protection, and protective clothing.Decontamination-The asbestos fibers remaining after the removal operations are
completed must be removed from surfaces and from the air This usually requires multiple cleaning and settling periods combined with continuous air filtration
All contaminated waste must be disposed of in accordance with EPA and local government regulations.

Throughput:
Chemical concentration:
During the 1960s and 1970s at Pugent Sound Naval Shipyard, asbestos-containing insulation products such as blankets, felts, and pads were fabricated [and
subsequently used in ships] at the shipyard (pg 5)
Thermal insulation materials for Naval and U.S. Maritime Commission ship applications were generally placed into three categories: insulating, lagging, and
fastening materials. Products such as felt, thermal block insulation, pipe covering, and high-temperature insulation cement were classified as insulating materials.
Lagging materials were applied over the insulating materials, and included products such as cloth, millboard, and finishing cement. Coatings, such as mastics or
adhesives, were considered fastening materials, and were used for securing lagging to the insulating material (pg 4)[thermal insulation pipe covering] was typically
affixed on pipes using iron wire or metal bands and wrapped with asbestos cloth. In order to create a smooth surface and to fill cracks and joints, dry asbestos
cement was mixed with water, and spread it into those areas where the rigid insulation did not fit tightly (pg 4)[asbestos felt] was often wrapped or fitted around
irregular shaped piping or equipment, such as valves and turbines (pg 5)preformed half-rounds (a term applied to molded asbestos insulation that was applied to
straight runs of pipe) were custom cut into pieces known as gores, creating sections that looked like orange slices. Each gore was held in place by wire, (pg 5)
FLETCHER-Class destroyer: 48 tons of asbestos-containing insulation; 34.4 tons of asbestos containing products (i.e., asbestos felt, cloth, twine, yarn, insulating
cement, and amosite sectional pipe covering) in machinery spaces, remaining 13.6 tons located in other ship areas; 1/3 of all amosite or amosite-bearing insulation
products located in engine and machinery spaces (pg 3)
weight percent of friable asbestos or asbestos-containing insulation products generally varied between 80% and 99% aboard various classes of U.S. naval vessels
from World War II until the 1970s (pg 3)Asbestos cloth insulation contained approximately 80-95% asbestos (based on type of grade) and was woven from long
chrysotile fibers (pg 4)coatings could contain chrysotile asbestos at concentrations ranging from 0.5 to 2% (pg 4)For straight runs, bends, and elbows of piping and
valves, thermal insulation pipe covering was used, and its chrysotile and/or amosite content generally ranged from 6 to 94% (pg 4)military standards specifications
required that asbestos felt contain no less than 95% amosite for the plain type and no less than 90% amosite for the water-repellant type (pg 5)

Process description: During removal of asbestos, adjacent areas are protected by sealing the work area with polyethylene sheeting, completely sealed and with air lock access and
subject to smoke testing to ensure airtightness. The work area is then subject to a lowering of air pressure, relative to surrounding areas, by means of filtered
extractors. The purpose of this is to eliminate any possibility of contaminating the adjacent areas with asbestos fibers. (1/2) Years later, more asbestos was found
and an order included a complete covering of the ceiling with a heavy cotton fabric, adhered with a polymer coating, to ensure encapsulation of asbestos that
was found impossible to remove, the coating to be finished with a white emulsion. In addition, to improve safety and access at high level, a scaffolded decking
was constructed in each subdivided area and demounted/re-erected as each area was completed. Another independent analyst company was used to carry out
air-monitoring and clearance inspection. (2/2)

was placed inside the abatement area. For protection, workers wore half-mask respirators and disposable suits. Removal began by wetting the tile with a wetting
agent. Tiles were then removed by using wide wood chisels and hammers to pry them up without breakage. The tiles were wet down as they were removed and
then boxed and bagged for disposal. Work area and personal breathing zone samples were collected, as well as adjacent area samples. After all the tiles were
bagged, the excess water was mopped up off the floor. The floor was then encapsulated with a commercial asbestos product to lock down any loose asbestos fibers.
Contaminated suits were removed in the decontamination space and bagged. After the encapsulant had dried, aggressive air samples were taken. (P. 2/3)

Chemical concentration: In the early twentieth century, asbestos was used as a filler to improve the technical properties of paints, particularly those used in shipyards and those applied to
bridges. The paints may have contained up to about 20% asbestos. Usage decreased after about 1950, although specialist textured paints or coatings continued
to be widely used in home decoration until the early 1990s. These paints contained approximately 5% chrysotile asbestos.Example of formulation of vinyl
acetate-based masonry paint for interior use: Talc 9.1 %; example of formulation of metal paints Talc as filler 11.5%

Data
Chemical concentration: During a leather factory fire in Merseyside, United Kingdom, in 1994, most of the fallout arose from asbestos bitumen roof paper containing roughly 50%
chrysotile. A low number of asbestos fibers were found on firefighter tunics (0.0029 f/cm3; range 0.0011-0.0043 f/cm3), and none was found on the firefight-
ers 'raincoats or policemen's uniforms. [A fire hose spray may have washed out airborne asbestos.]Thermal protective clothing, gloves and helmets that contain
asbestos usually contain chrysotile asbestos. In the United Kingdom the helmet covers for navy firefighters, which completely enclose their head and shoulders,
used to be made of chrysotile asbestos. Breathing zone samples from users of both new and old helmets with unlined asbestos cloth covers were analyzed and had
fiber concentrations of 2.30 f/cm3 and 1.38 f/cm3, respectively.

Production, import, or use volume: The world production of asbestos increased by 50% between 1964 and 1973, when it reached a level of nearly 5 million tonnes. The projected world demand for
asbestos, based on historical consumption figures and usage patterns through the mid-1970s, indicates more than a doubling by the year 2000. However, world
production figures for the period 1979-83 showed a decline in production. The only substantial increase in asbestos demand seems to be occurring in developing
countries, and in some European countries. Afghanistan 4000 (1979)Argentina 1371 (1979) 1261

Process description: Asbestos ore is usually mined in open-pit operations which includes drilling, blasting, loading broken rock, and transporting ore to the primary crusher or waste
to dumps, unloading ore from the open pit, primary crushing, screening, secondary crushing, conveying and stockpiling wet ore. A drying step follows, which
involves conveying the ore to the dryer building, screening, drying, tertiary crushing, conveying ore to dry-rock storage building, and dry-rock storage. The next
step is the milling of the ore.

Process description: "Friction materials serve in a variety of ways to control the acceleration and deceleration of vehicles and machines. The friction materials may be resin- or rubber-
bound composites based on asbestos, metallic fibers, or a combination of other fibers. Trucks and off-highway vehicles usually have very large drum brakes; only
a few have front disk brakes. These friction couples usually operate at higher friction levels and temperatures than those of passenger cars. Large aircraft are
equipped exclusively with disk brakes that contain multiple rotor and stator arrangements having the most popular friction couple consisting of a sintered friction
material sliding against a high temperature resistant steel. The newer aircraft brakes consist of carboncomposites serving as both the rotor and the stator. (1/13)"
Chemical concentration: Prior to the mid-1970s, the most common type of friction materials in use in brakes and clutches for normal duty for original equipment installations and for the
aftermarket were termed organics. These materials usually contained about 30-40 wt % of organic components and were asbestos-based. (2/13)

Parameter Data
Chemical concentration: The asbestos content of drywall finishing products (e.g. joint compound, texture, and tape) historically ranged from approximately three to 15% chrysotile
by weight. It has beensuggested that, when joint compound products were first introduced, formulations contained 10-15% asbestos, and that the asbestos
concentrations decreased with time (CPSC 1977b). Only the chrysotile form of asbestos was intentionally added as an ingredient in joint compound formulations;
amphibole fibers (e.g. tremolite, amosite, crocidolite) were not used as ingredients in joint compounds (Phelka and Finley 2012). However, industrial talc was
also used in somejoint compound formulations, and some chrysotile asbestos and industrial talc deposits contained trace levels of tremolite asbestos (Fiume et al.
2015). [PDF Pg. 3]Latex-based textured paints contained limestone, lesser amounts of mica, and 1-5% chrysotile asbestos (Anderson and Farino 1982; Anderson
et al. 1982). [PDF Pg. 4]Specifically, Fischbein et al. (1979) reported that four of 15 industrial taping and spackling compounds contained tremolite structures at
concentrations ranging from 1 to 2% (Sterling Ready Mix, Sterling All-Purpose) to 8-12% (S-C-L Taping Compound) (Fischbein et al. 1979). Rohl et al. (1975)
reported that one of the 15 consumer products under evaluation (Metro spackling putty) contained 4-6% tremolite structures (Rohl 1975). [PDF Pg. 5]

stearate), and reduced foaming tendency (silicone compounds) . Many of the antioxidants used are substituted phenolic compounds such as 2,6, di-tert-butyl-4-
methyphenol.

Parameter Data
Process description: The carpet was vacuumed or wet cleaned for a period of approximately 65 min to allow the collection of a sufficient volume of air to attain an analytical
sensitivity of 0.005 s/cm3 of air. The carpet was cleaned in two directions, the second direction at a 90° angle to the first.Both dry vacuuming and wet cleaning
of carpet artificially contaminated with asbestos fibers resulted in a statistically significant increase in airborne asbestos concentrations. The increase did not vary
significantly with the type of cleaning method (wet or dry) or with the two levels of asbestos contamination applied to the carpet.Although this research revealed
significant increases in airborne asbestos concentrations during cleaning activities in a controlled study under artificial, simulated conditions, it is not known if
such increases occur in real-world custodial operations.
Chemical concentration: Reference for the following was not provided in the text.Carpet concentrations range from 8,000 to 2 billion structures per ftA2Bulk samples varied from 30 million

Process description: Although asbestos is being phased out of most consumer products, it is still used commercially in specialty paper products, such as gasket material; certain
building materials, such as roofing felts and shingles; and friction products, such as elevator brake shoe lining and automobile clutch disks. Rock containing the
asbestos mineral is mined with explosives. The blasted rock and rubble go through a series of crushers and screeners. The asbestos material is separated from
the rock for further processing, and the waste rock, or tailings, are disposed of in on-site waste piles. Mined asbestos was usually further processed and mixed
with other material, such as cement or paper, or was used as a binder or reinforcer. For example, asbestos was often mixed with dry cement and water. This
"mud" mixture was trowelled on to pipe fittings, such as elbows and valves, and trowelled onto equipment, such as residential boilers. Canvas-wrapped corrugated
cardboard impregnated with asbestos, commonly called air-cell insulation, was often used to insulate straight pipe runs. All mixtures of asbestos with another
material, such as concrete or paper, are examples of ACM. If ACM was used as a material of construction it also may be known as Asbestos Containing Building
Material (ACBM). (pg 1005)

Parameter Data
Process description: Roof materials were abated by cutting out sections with a power saw. Work employed wet methods (HEI, 1991, OSHA, 1996). Water from a hose was used to
wet the roof before abatement and when cuts were undertaken. Roof material was removed and placed into a chute (about 3 foot diameter). The chute was also
periodically wetted and was connected into a dumpster. This dumpster was sealed, except the entering chute, with plastic and water from the hose was periodically
applied to the dumpster via the chute to maintain material in a wet condition. However, due to the consistency of this roofing material wetting was not effective
and some emissions occurred.
Chemical concentration: Roof materials were identified as ACM by Polarized Light Microscopy and was estimated to be 5 - 10% chrysotile.

procedure for the chimney flues is that they will be cut into small pieces of manageable size (e.g., 1.2 m x 0.8 m) by flame-cutting or any other appropriate method
with the assistance of hand-held tools on the spot by operatives who will work from intermediate working platforms between chimney platform levels.Concerning
demolition of concrete chimney wall after clearance of ACM/DCM, the principle is that the upper portions of the chimney will be cut into pieces by hand-held
tools on the spot by operatives who will work from working platforms inside the chimney. Hydraulic breakers will be an option for use for the remaining lower
portions of the chimney.The demolished concrete debris will then be broken down and removed by hydraulic excavators and loaded on to trucks for transportation
to the designated disposal site. Duringthe demolition work, water sprays will be used to suppress excessive dust generated by the processes

Process description: Pilgrim Glass Company's plate press line in the Hot Metal Shop:"The gatherer uses a long-handled rod to extract about 4 lbs of molten glass from the continuous
tank furnace and drops it on to a press. The presser forms the plate. Next carry-in person #1 transfers the plate to a carbon holder using a scoop. Carry-in #2, using
asbestos gloves, stacks the plates in columns of 3 with 4 small irregular shaped pieces of 1/4 inch asbestos mill board separating each plate. Carry-in #2 removes
his gloves to transfer the column of 3 plates to the hot end of the #2 lehr using a long-handled paddle. The lehr is a temperature controlled enclosed conveyor
belt used to slow the cooling of newly formed glassware. This slow cool process prevents the glass from cracking. The lehr's inlet temperature of 9000F drops
500F for every 6 feet the belt moves. Resident time in the lehr is 2 hour and 45 minutes. At the cold end of the lehr (800F) a separator removes and prepares the
plate for shipping. The small 2 to 5 inch irregular shaped pieces of asbestos mill board are dropped into a 3 foot sauare cardboard box. When the box is full it is
returned to the beginning of the plate press line to be reused in the plate stacking process. These asbestos pieces are used until they deteriorate or are lost. About
once a month the foreman's helper must break new pieces of asbestos mill board by hand. He performs this task outside in open air. The mill board is received in

Process description: The existing polish was removed in a 10-minute time period using a commercial liquid stripping agent. Immediately afterwards, the floor was cleaned, over a
9-minute period, using a liquid cleaning solution. The floor was then allowed to dry for approximately 20 minutes. The floor was then waxed during a 9-minute
time period using a commercial polish. Following a 30-minute drying time, the floor surface was buffed for approximately 15 minutes using an upright drum-type
rotary buffer. [PDF Pg. l]Tile removal by cold techniques involved placing blocks of dryice in contact with the tile surface to freeze the underlying adhesive.
Depending on the condition of the tile and strength of theadhesive bond, the individual tiles were removed by hand orcarefully scraped up with a removal tool
that resembled a heavyduty wall scraper. [PDF Pg. l]Hot removal techniques were then used on the second sectionof flooring. This technique involved the use of
heat guns (BoschTools, Model # 1942) to heat the tile's underlying adhesive afterwhich the tile could be removed by the use of a scraper to prythe tile from the
underlying surface. [PDF Pg. l]The installation process began by laying down a coat ofadhesive to the entire test area. Following a short time periodto allow the
adhesive to "set up" the workman began layingdown 1 ft. square vinyl-asbestos floor tiles. Installation of thetiles was completed in 80 minutes. As in the removal,
both personnel and static air sampling were performed during the tile installation. [PDF Pg. 2]

Process description: "The mechanic performed tasks associated with flange gasket replacement or complete valve overhaul on a steel work bench with approximate dimensions of
1.5 m long by 0.6 m wide by 0.9 m tall. Flanges and valves were secured to the table with table-mounted vices, as appropriate. Flange gasket work involved
the removal and/or installation of the associated flange gaskets. To simulate a complete gasket replacement, the mechanic then fabricated a replacement gasket
from sheet gasket material and installed the new gasket onto the flange. Valve overhaul work involved the replacement of valve packing material, replacement
of bonnet gaskets internal to the valve, aswell as replacement of the affiliated flange gaskets. For each valve overhaul, the existingbonnet gasket was removed
and a replacement gasket was fabricated prior to installation. The bonnet surface was cleaned using a scraper and hand wire brush and a new bonnet gasket was
fabricated from sheet gasket material and installed into the valve. (4/17)"
Chemical concentration: The asbestos bulk content of the gaskets removed from the flanges and valve bonnets ranged from 45% to 95% chrysotile, and the bulk content of the gasket
material installed ranged from 50% to 80% chrysotile. In addition, the asbestos bulk content of the packing material removed from and installed in the valves

Process description: The brake removal process was similar for all pieces of equipment, with slight differences only in the work practices exhibited by each mechanic. The mechanics
worked on each piece of equipment oneat a time. To disassemble the brakes, the external brake housing was first removed from the tractor or loader backhoe
using a manual or power wrench to loosen bolts holding the housing in place. On four occasions (Eql, Eq9, EqlO, and Eql2), a blowtorch had to be applied to
facilitate loosening of the externalhousing bolts. Once the external housing was removed, the entire brake assembly was removed from the vehicle. At this point,
the mechanic at the Stockton facility would blow out the assembly and work area with compressed air and then repeat the entire processfor the second brake
housing. Once both complete assemblies were removed, he performed bench work, which entailed disassembling the drum linings from both brake assemblies.
Using a slightly different order than the Stockton mechanic, the mechanic in BigRock, IL, completed the entire brake removal process on the first assembly before
beginning the process on the second one. (P. 6/19)
Chemical concentration: Asbestos content in automobile brakes is generally between 30 and 50%. (P. 2/19)historical studies have shown that brake wear debris collected from an automobile
dynamometer or drum brakes contains on average between 0.02 and 4.5% asbestos, with the majority of wear debris samples containing ,1% chrysotile. (P. 2/19)In
summary, the asbestos content of the brake lining averaged 19% chrysotile by weight (range: 1-39%) as measuredby XRD and 20% chrysotile by area (range:
0.5- 70%) as measured by PLM (Table 2). (P. 9/19)

Process description: Two operators were in the enclosed "Penthouse" area removing two inch Thermobestos from the piping and equipment. The first operation was to spray the
insulation with a fine spray of water to keep the dust to a minimum. The wires were cut and the two inch insulation was removed and asided into plastic bags. The
insulation was broken apart after the bags were closed. The closed and tagged bags were removed by the third member of the crew and the bags were positioned
near the edge of the fifth floor. We had a metal box (five feet x five feet x one foot) raised to the fifth floor and approximately ten tags were placed in the box
and lowered to the ground level and asided to large dump cart. The cart was used for only asbestos and was going to a dump that had been designated by the
Environmental Protection Agency. [PDF Pg. 4]

Process description: The floor area was roped off in a 40'x20' section with asbestos caution signs posted by each corner. Natural Monsanto polyethylene sheeting, six mil thick, was
unfolded and spread on the floor; The portion of the job monitored consisted of removing "1" inch thick insulation from a "1" inch diameter steam line. The
job was twenty feet high and required a scissor type scaffolding to reach. The stage of the scaffold was "80" inches x "28" inches and had safety bars around
the perimeter "36" inches high. The operators placed a steel fifty-five gallon drum on the stage and lined it with a four mil polyethylene bag.The insulation was
sprayed with a fine mist of water prior to cutting into the canvas jacketing. The jacketing was removed and asided into the drum. Next, the wires were snipped
and the insulation was removed and placed In the drums. Martin Marietta personnel requested the pipes be wiped with a damp cloth to remove any excess dust
after the Insulation was removed. This operation was accomplished and the cloths asided into the drums. The bags were sealed In the full drums and a caution
asbestostag was put Inside the drum. The cover was secured with a screw type clamp and a caution asbestos tag was taped to the cover. The floor was squeezed
and wet mopped at the end of the day. [PDF Pg. 4]

Parameter Data
Process description: Engine Overhaul:The overhaul was performed over a three week period. The first week of work on this project was spent disassembling the R2800 engine. The
piston engine was stored in a large metal "can" and was removed from its can on day 1 and brought into the facility with a forklift late that day. Broadly, the
disassembly process began with removal of the air foils, intake and exhaust tubes, the ignition wiring, distributors, magneto, wiring harness, and all miscellaneous
exterior parts. Next, the eighteen cylinders were removed. The nose section was then separated from the power section and disassembled. The power section
was then separated from the supercharger (blower) section, and disassembly of the interiors of these sections proceeded separately. Once removed from the
power section, the cylinders were disassembled separately. Part of this work was done in a separate disassembly building using a specialized machine to remove
the pistons. The cylinders and their components were then returned to the assembly building for sandblasting, painting, and reassembly. The third week of the
overhaul was spent in reassembling the engine. During the second week, no sandblasting, scraping, gasket removal or other work of any sort was done to any
of the disassembled components, except that all the appropriate large, exterior pieces (e.g., the housings for the nose section, power section, and supercharger)
were painted. Painting of these components is a normal part of an overhaul, and presents no opportunity for asbestos exposure. Reassembly proceeded in reverse
from disassembly. The interior gears, shafts, and other components of the nose, power, and supercharger (blower) sections were reinstalled, the power section was
joined to the supercharger section, and the nose section was joined to the combined power-supercharger sections. The cylinders were painted and reassembled
separately, then reinstalled on the engine, followed by the distributors, magneto, wiring harness, intake and exhaust tubes, the ignition wiring, the air foils, and all
miscellaneous exterior parts.Cylinder Change:This job consists of removing any wiring, intake or exhaust tubes, air foils, and anything else that would interfere
with the cylinder removal, removing the valve rocker arm covers, removing the push rods, and removing the cylinder itself. A replacement cylinder is then
installed, followed by reassembly of the above components. The gaskets on the rocker arm cover-cylinder face are changed, and also the gaskets on the push rods,
intake/exhaust tubes, and any other gaskets encountered. The first cylinder change was performed on cylinder number 14 during the first week of this project,
and the second was on cylinder number 6 during the second week.Clutch Rebuild:Mechanical clutches often contain asbestos-containing facings. Each of the two
clutches had a high ratio and a low ratio section. The job consisted of disassembly and separation of the high and low ratio sections of both clutches and removal
of the facings from each of the four sections. New facings were then installed and the clutch was reassembled. The clutch disassembly was done during the first
week. The components were left on a table in the facility away from the overhaul area. Installation of the new facings and reassembly of the clutch was done
during of the second week of this project.Ignition System Rebuild:A complete engine overhaul would include inspection and rebuilding of the ignition system
including the magneto, two distributors, the air pumps within the distributors, and all subcomponents. This was done on during the second week using these parts
from the R2800-30W that was being overhauled.

Life cycle description: Chrysotile asbestos, also called white asbestos, is one of six types of the mineral fiber asbestos. Its use has been banned in 50 countries, including the European
Union. However, it is still used in developing countries in asbestos cement building materials. Exposure to chrysotile asbestos can increase the risk of lung disease.
An overview is available from the World Health Organization. Chrysotile asbestos is white to grayish green thin, flexible curved fiber. It can also be slightly
tan colored. Chrysotile asbestos is the most common form of asbestos. It is slightly soluble in water. Asbestos minerals in general do not have an odor or taste.
Chrysotile asbestos is mined from deposits in Russia, China, Brazil, Kazakhstan and Canada. USE: Chrysotile asbestos is still used in some parts of the world in
cement building materials. Chrysolite fibers had been used in paper and plastic products. [PDF Pg. 14]

Production, import, or use volume: peak production in Australia occurred in 1970s at 400,000 tons, importation peaked at 15,000 tons in 1985 just after production in Australia ceased in 1983.
Process description: Manufacture of compressed asbestos fibre sheeting (CAF) and gasketsCompressed asbestos fibre (CAF) sheeting, using raw chrysotile, is manufactured in
Australia. The majority of the CAF sheeting is then exported and the remainder processed into finished cut gaskets (for use in industrial applications).Bags
of raw chrysotile are inspected to ensure there are no broken bags. If broken, the bags are sealed by operators and immediately consumed in the manufacturing
process. Where necessary, the surrounding area is vacuumed using high efficiency cleaners. The polyethylene bag is removed from the raw chrysotile using
a debagging machine, which is enclosed and under negative pressure. The machine disposes of the chrysotile containing bag automatically into a fresh sealed
plastic bag. The sealed bag is then removed from the machine manually.The production of CAF sheets is a closed process. The chrysotile fibres are transferred
under negative pressure through conduits attached to the bagging machine to the hammer mill, where the fibres are milled and introduced into a mixing machine
via a closed loop system. The fibres are then encapsulated by combining with various grades of rubber to form a wet mash, which is then passed through a
calendering machine to form CAF sheets.The CAF sheets are then printed and trimmed using knife action tooling, for example, a guillotine. The CAF sheets
are cut to size using knife bladed tools. For spiral wound gasket production, imported rolls of asbestos filler material are slit using a rotary die block. The slit
material is then wound between alternate layers of stainless steel. The finished goods are stored prior to packing for distribution to customers.Gasket off-cuts
also undergo secondary manufacturing. These off-cuts are recycled for further use.Gasket cutting from CAF is carried out by other workshops.Manufacture of
Epoxy resin adhesivesChrysotile is used as a 'non-sag' additive in the formulation of an epoxy resin adhesive for affixing marble and granite panels to the walls of
buildings.Chrysotile is imported in compressed form in 15 kg paper bags, wrapped in plastic. Approximately 500 bags are imported in a shipping container which
is stored on site.The liquid ingredients are first added to the mixer. Bags containing chrysotile are manually opened, the chrysotile weighed and then added to the
mixing vessel. A lid is placed on the vessel which is exhaust ventilated. Mixing takes approximately one hour. The product is a thick paste and is mechanically
forced out of the vessel using a plunger. The product is produced in batches for approximately 50% of the year. It is packaged in 2, 4 or 20 litre plastic buckets.Any
spills or loose asbestos released during cutting are collected during vacuuming and waste is disposed of in drums to a licensed contractor.

Process description: After a task order or work order is issued, the participants review the procedure, assemble the necessary equipment and materials, and prepare the work site.
Area preparation is not as extensive as for an abatement project, but items must still be protected from contamination by water and debris. Some procedures and
regulations for using glove bags, for example, require "pre-cleaning" the work area and placing a layer of 6-mil (0.15 mm) plastic underneath the glove bag during
the work. During the work, workers use water to wet debris and remove and/or repair asbestos insulation. After the work, the area must be thoroughly cleaned,
and air samples are taken for final clearance. (3/11)

Production, import, or use volume: The total U.S. adhesive production in 1999 was estimated at approximately 15 billion pounds, and was anticipated to grow by 2 billion pounds by 2004 (pg 21 of
168)
Process description: This ESD focuses on the formulation of an adhesive product. Adhesives are formulated by mixing together volatile and nonvolatile chemical components, such
as binders and components in sealed, unsealed, or heated processes. The specific formulation process used depends on the type of adhesive being produced (pg
24 of 168). Because many adhesives are designed to set or react when exposed to ambient conditions, most are formulated in a sealed process. Typically, solid
or liquid adhesive binders and components are unloaded from transport containers (tank trucks, totes, drums, sacks) either directly into the mixing equipment
or into intermediate storage tanks. If the component is in the solid/powdered form, it is assumed that some amount of the component will be lost during the
transfer as dusts released into the workspace air that will be subsequently vented to the air outside of the facility or settle out within the workspace. Dusts that
collect on vent filters or within the workspace are collected and disposed. In a sealed process, the mixing occurs with no direct contact from the workers in closed
vessels. Typically, a high-speed dispenser combines the components using precise settings to avoid overstirring, which may adversely affect the viscosity and
other properties of the adhesive. It is assumed that the sealed system captures the volatile components released during the mixing process and vents them through
a stack to air outside the facility (pg 24 of 168). Adhesives may also be formulated in an unsealed process in which the tanks and transfer operations are open. It
is expected that solution adhesives containing low-volatility solvents (i.e., water-based adhesive dispersions) or other components that are relatively stable under
ambient conditions are formulated using open mixing tanks and transfer operations (pg 27 of 168). Adhesives may also be formulated in an unsealed process in
which the components are melted and mixed into a molten liquid adhesive product, and subsequently extruded, poured, or otherwise formed into a solid hot-melt
adhesive product when cooled (pg 29 of 168).
Throughput: Table 3.2 (pg 43 of 168) shows the average annual facility production rate of adhesives which is 17 million kg/site-yr for large 50 sites and 1.6 million kg/site-yr
for other 542 sites.
Number of sites: According to the 2003 County Business Patterns data, 592 establishments within the United States were classified within the NAICS code of 32552 and employed
a total of 21,048 workers (pg 21 of 168)
Chemical concentration: Table 3-3 (pg 50 of 168) presents the general formulation data for adhesive products as follows (as weight fraction of adhesive components): Elastomer or
adhesive products - 0.11-0.85; Solvent - 0.01-0.75; Viscosity control - 0.002-0.4; Pigment - 0.02-0.36; Tackifier - 0.02-0.35; Filler - 0.33-0.35; plasticizer -

Diatomaceous earth is combined with other materials tomake a powdered filtering substance. The ingredients are loaded by hand into barrels and mixed by a
machine which rotates them. During the hand loading and bagging sequences of the operation, dust can be generated, (page 4)Batching area: The first step in the
filter manufacturing process takes place in this area of the plant. Raw cellulose and asbestos fibers are mixed in a large holding tank. Water, hydrochloric acid,
and organic resins are added to the mix. This slurry is then pumped to the extractor machine. The asbestos portion of the solid fraction of the slurry ranges from
0 to 100 per cent (page 4)Extractor: The liquid portion of the slurry is removed by the extractor. At the same time, the solid portion is laid into sheets by the
extractor and dried by flame heat. The sheets are cut and stacked in different sizes during the last step of the extractor operation, (page 4)Die Cutting : The sheets
of filter material are cut to customers' specifications by the "die cutter" who operates the die cutting machine manually. The machine is enclosed partially and
local exhaust ventilation is available. After the filters are cut, they are inspected, branded, and packed for shipment, (page 5)Fiberizer: The waste materials are
reclaimed instead of being discarded. The waste asbestos filters are loaded manually into a fiberizer where they are shredded and loaded into sacks. The potential
for excess airborne asbestos dust is greatest in the fiberizer area . The machine is run from 5 to 10 days per month. One worker operates the fiberizer and another
one assists him by bagging the shredded material, (page 5)

Process description: Superfund site remediationCleaning process- Goods on pallets were placed in area 1 and subsequently cleaned of the dust that had deposited on them using special
aspiration equipment fitted with absolute HEPA filters and eventually their protective PVC wrapping was removed.- In area 2 the pallets were encapsulated.- In
area 3 they were re-wrapped.- In area 4 they underwent provisional stacking awaiting analysis by the competent bodies.- Area 5 was used to stack goods that were
no longer contaminated and could be retrieved for use (sale) pending collection and transfer to their final destination.- Remediation wastewater was filtered before
being released into the sewer system.Remediation of asbestos concrete manufacture plant- first removal of hazardous and nonhazardous waste (piles and bags
containing asbestos powder) located inside the buildings;- Removal and disposal of asbestos wastes from the industrial cycle, cemented using industrial devices;-
Removal and disposal of all the silos and machinery present inside the plant heavily contaminated by asbestos dust;- Removal and disposal of all horizontal and
vertical partitions and roofing in asbestos concrete material (Eternit);- Removal and disposal of asbestos pipelines;- Emergency action on asbestos contaminated
soil using special capping techniques. For the unpaved yard area, inside the plant perimeter, the following were performed: Soil leveling; Building of a retaining
wall along the perimeter about 50 cm high with a linked HDPE layer; Installation of drainage pipes to manage the surface water flow; Placement of a proper
gravel layer to allow the transit of light mechanical transport vehicles.- Decontamination of the whole area;- Final encapsulation.During all operational phases,
the following complementary operations were carried out for each single subarea:- Decontamination of workers using a dedicated four-step decontamination unit
(contaminated equipment area, shower area, air lock, and clean area);- Decontamination of materials removed using a special three-step decontamination unit (bag
washing area, packing area, removal area);- Decontamination of polluted wastewaters used to clean devices, materials, packaging, and workers using a specific
treatment and collection unit;- Campaign of environmental and personal monitoring of airborne asbestos fibers using various fixed and portable samplers, at low
and high flow rates, and subsequent analysis with SEM and PCOM techniques; - Formal validation of all the work by public surveillance bodies.For Marine
Area:- In order to carry out operations in safety conditions, a preliminaryinvestigation was conducted to identify any buried, unexploded military devices.- A
ban was imposed on swimming in the area.- Dedicated mechanical devices (underwater excavator, air suction systems) and of specialized divers was decided. -
A mobile underwater barrier of big bags filled with sand and marker buoys was set up to be gradually moved around the remediation area.- Residual banks
were removed using an underwater excavator.- Local on site inspection and removal of any remaining small-size materials.- Removal of all the sediments using a
manual aspiration pipe around the piles already submitted to mechanical removal and all over the site.- Environmental monitoring of asbestos fibers by atmospheric
dispersion analysis with PCOM (for personal sampling in working areas) and SEM (for environmental sampling).- Specific monitoring planning through biological

Production, import, or use volume: PV is listed but is for Iran not the US. In 2007, Iran imported 55,000 tons of Chrysotile asbestos per year and asbestos cement plants contribute nearly 94% of the
total national usage. 30,000 tons of chrysotile is annually used to produce asbestos cement sheets.(pages 1 and 2 of 6)The Iran factory studied produced 60,000
tons of asbestos cement sheets annually (page 2 of 6). Iran uses 3-4% of global asbestos (page 4 of 6).
Process description: Asbestos cement sheets were manufactured by a wet process. The factor had the following major processes:l) feeding of raw materials (20% chrysotile, 80%
cement)2) mixing - mix is weighted and water is added to make slurry. 3) molding of sheets - mix is charged into molds4) Unloading car5) cutting6) drilling7)
sheet storageThe AC sheets are manufactured by mixing chrysotile fibers and cement in a wet process. In the process, the mixture is weighted, and water is added
to the mixture for making slurry. The mixture is charged into molds during the steam process. Asbestos cement sheets production requires large numbers of
finishing machines such as cutting and drilling equipment to make the end products. At the end of the process, AC products are transported by lift truck, (page 2

Process description: The local age heat treatment process was first located in Building 800 across from the nitride area and was used on the X-211 engine. On this engine the combustor,
collector, and tubing were heat treated. The process involved cutting fire brick and shaping it to conform to the part(s) to be heated. Nichrome wire was used as the
heating element and was inserted in the contoured section of the fire brick. This "furnace" was held to the part being heat treated by a tack-welded nichrome wire.
Next, a number 20 chromalloy thermacouple with asbestos coating was tack-welded to the part to monitor the temperature during heating and cooling. After being
cut to size, back-up insulation material was placed so as to cover the furnace. This insulation, which came in peach-colored sheets, was manufactured by the Johns
Manville Company, and was thought to be composed of asbestos. Next, loose bulkinsulation material, greyish-white in color, and also thought to beasbestos, was
used to fill in around the furnace and back-upinsulation. The bulk insulation was stored in cardboard boxes and was placed by hand or with shovels on top of the
back-up insulation material to a depth of several inches. Finally, an asbestos blanket was used to cover the loose bulk insulation.These materials were used from
1956 until mid 1958 when an olive-green colored material was added to the loose bulk insulation. This came in bulk containers also and was thought to have been
fibrous glass. In 1959, the heat treatment area was moved to the southeast area of Building 700. Large X-211 parts were treated there. In about 1961, the heat
treatment area was moved again, this time to the J6 area of Building 700.From 1959 until 1966, the materials used for heat treatment wereidentical to those used
in Building 800, as described above. Aboutl965 or 1966, vermiculite became the major loose, bulk-insulatingfiller. It was stored in garbage cans. Fiberfrax was
introduced inl965 or 1966 as the blanket covering the bulk insulation. After 1975, the use of loose insulation was discontinued with the replacement of nichrome
wire heating coils with a quartz lamp. [PDF Pg. 4-5]
Chemical concentration: Of 11 settled dust and material samples collected and analyzed forasbestos. only one contained asbestos (20-25% chrysotile). This sample was obtained from an
overhead cold water insulation jacket located at the current heat treatment area to assess the possibility that settled dust samples contained asbestos from sources
other than process materials. [PDF Pg. 9]

Process description: Raw asbestos fiber, pigment, and filler are mixed dry to form a cohesive mass to which liquid constituents are added if required. Although the mixture is exothermic
(it generates heat during mixing), it may need to be heated further in order to reach a temperature of at least 300"F at which point it is fed into a two rollmil
where it is pressed into a slab or desired thickness. The slab isthen passed through calenders, machines with rollers, where it acquires a uniform finished thickness
(Krusell and Cogley 1982). Embossing, pigmenting, and other surface decoration is done while the material is still soft. The tile is then cooled using one of three
processes: immersion in water, spraying with water, or placing in a refrigeration unit. In order to minimize shrinkage after cutting, the tile is allowed to air cool
before it is cut into squares and waxed. [PDF Pg. 1]
Chemical concentration: Typical concentrations of asbestos in vinyl floor tiling are 5-25% [PDF Pg. 1]

Process description: Asbestos-cement pipe is made of a mixture of Portland cement (42 to 53 percent by weight), asbestos fibers (15 to 25 percent by weight), and silica (34 to 40
percent by weight). These materials are combined with water and processed into a pliable mass that is wound around a steel cylinder and then compressed and
cut into 10 or 13-foot lengths. The product then goes through a curing process, known as autoclaving, that involves immersion in water orpressurized steam.to
enhance corrosion resistance to high sulfate soils and waters. Cured pipes then undergo a finishing process that includes machining the ends and, optionally, lining
the pipe with gilsonite coatings, asphalt-based coatings, or other coatings to protect the pipe from acidic or corrosive fluids (ICF 1985). [PDF Pg. 28]

Process description:
Asbestos Diaphragms are employed in the chlor-alkali industry for the production of chlorine and other primary products such as caustic soda. There are presently
three types of electrolytic cells in commercial use; asbestos diaphragm cells, mercury cells, and membrane cells (Kirk-Othmer 1985). All electrolytic cells operate
on the same principle - an electric current decomposes a solution of brine into (1) chlorine, liberated at the anode (positive electrode) and (2) caustic soda and
hydrogen, liberated at the cathode (negative electrode). The ratio of chlorine to caustic soda produced during the process is 1:1.1 by weight (Chemical Week
1982). Most of the chlorine produced in the United States is made using electrolytic cells (Kirk-Othmer 1985). [PDF Pg. 8]

Process description: Asbestos stripping procedures (pg 7-8 of 12): 1. Notify EPA of intention to remove, demolish or renovate asbestos at least 20 days prior to commencement. 2.
Survey the job and draw up an operational plan considering: a) The means for sealing off the work area, b) Method of transporting asbestos waste from the work
area, through the barriers to transportation, c) Identify locations and provisions for change of rooms, toilet, and showering facilities . d) Choice of protective
equipment e) Contamination control procedures, f) Identification of sanitary land fill, g) Ventilation openings, drains, etc., to be sealed or filtered, h) Water and
electrical services, i) Monitoring facilities and frequency of sampling, j) Identification of the equipment to be covered/removed, k) Provisions for maintenance.
1) Security system. 3. Air sampling to determine background fiber levels. 4. Begin operation by removing designated equipment. Cover remaining equipment
and hard-to-clean surfaces with PVC or polyethylene sheet. Seal openings, such as windows, doors, ventilation systems, etc. 5. Seal off the area with PVC or
polyethylene sheet. Overlap joints and heat seal or tape. If the area to be stripped is large, it should be compartmentalized. Access into the work zone must be
through an airlock system which may be incorporated into the changing and washing facilities. The work area should be kept below atmospheric pressure with an
exhaust fan equipped with an absolute filter. Floors should also be covered. 6. The barrier, airlock system should be constructed so that the worker passes from the
work zone into successively cleaner areas, e.g., work zone to vacuum area to asbestos clothing change room to shower room to personal clothing change room to
external unrestricted area. 7. Asbestos removal: Water spraying with respraying as required if dust occurs during the removal of the material by dislodgement and
scraping. The water should be amended with a wetting agent. Dry stripping requires EPA approval. (40 CFR 61.22(d)(ii). 8. Air sampling inside and outside the
work zone should be conducted to ensure that the barriers are effective and to confirm the suitability of the respirators. 9. The asbestos stripped should be caught
and not allowed to fall to the floor, if possible. Asbestos should be bagged and labeled according to OSHA regulations using 6 mil or heavier plastic bags. The use
of SS gallon drums is strongly recommended as secondary containment for the bags. The material should not be allowed to accumulate, and none should be left
unbarrelled at the end of the day. Bags and drums must be wiped down before removal. 10. All of the surfaces should be washed down or vacuumed after stripping
and removal is completed. Work should progress from the top to the bottom. 11. It is virtually impossible to remove all of the asbestos and once the stripping
is completed, but before the barriers are removed, the surfaces should be coated with a sealant. An emulsion-type paint is acceptable. 12. Air sampling should
be performed before removal of the barriers and thereafter over an extended period of time to ensure that effective control has been provided. 13. Dismantle the
barriers and dispose of in a landfill.

Process description: There are four general control measures to reduce asbestos exposure risk:* removal;* enclosure;* encapsulation; and* maintenance and reassessment program.
Typical removal process:material wetting (surfactants enhance wetting but are not required)material removal (stripping)unit or section cutting or disjoininglocal
exhaust ventilation/collection systemwaste handling and cleanup (dry vacuuming, wet vacuuming, wetmopping, sweeping, hand wiping, etc.); andwaste disposal.
Enclosure consists of constructing an air-tight barrier between the Friable Asbestos Material (left intact) and the building occupants. Encapsulation consists of
applying a penetrating or bridging sealant to the Friable Asbestos Material (left intact) to render it nonfriable. Maintenance and Reassessment consists of special
housekeeping procedures, maintenance precautions, and inspection procedures to minimize the exposure risk.

Parameter Data
Process description: [PDF Pg. 3]Chemical Stripping Methodology: In this operation, the asbestos abatement contractor typically removes the movable furniture and materials from
a room or group of rooms. Then, polyethylene plastic sheeting is taped to the walls from the floor to a height of approximately 4800 . The purpose of this is to
protect the wall covering from dirt, dust, and splashing. The contractor then covers any remaining appurtenances and seals all means of air ingress and egress
into the area thus creatinga containment zone. Because of the potential for asbestos emission, air filtration devices are positioned in or near the area so that any
emission within the abatement area flows across high-efficiency particulate air (HEPA) filters before being discharged into the environment thus trapping any
errant fibers. Once the containment zone is erected, the contractor assures that the work environment is under negative pressure. Then, the contractor mists the
floor with amended water to decrease the dust load and uses spud bars to lift the floor tile off the floor. The floor tile is then placed into disposal bags and loaded
into a dumpster for delivery to an appropriately licensed landfill. Following this, the contractor liberally spreads a chemical mastic removal liquid onto the floor,
waits for a period of time, and uses a low-speed buffer (175el000 rpm) with a soft stripping pad to agitate the mastic remover over the floor. Peat moss, sawdust,
or other absorbent is then applied to the surface, mixed together to form a semi-solid, and manually scooped into disposal bags. The floor is then wetmopped
and allowed to air dry.Wet Grinding Methodology: The wet grinding methodology shares similar preparatory phases with the chemical stripping method. Both
methods require the erection of a work area separated by plastic barriers to exclude the work area from the rest of the facility. The exception is that walls are
covered from floor to ceiling to inhibit fibers from plating out onto vertical surfaces. The mode of floor tile removal is similar as well. The difference resides in
the removal of the floor tile mastic.At the start of the floor tile mastic removal activity, the floor isliberally covered with water and a small amount of fine sand. A
lowrpm floor tile buffer is then fitted with a hard steel mesh disc andapplied to the sand and water mixture. Some technique is required to adequately clean near
edges and oftentimes, doors must beremoved to sufficiently clean the jamb area. Those areas notreachable by the buffer such as corners, must be hand scraped
using a wire brush or scratch pad. This process also generates a sludge, which is a mixture of the water, sand, and the mastic compound. The sludge is then
collected and containerized similar to the chemical stripping methodology. The floor is then wet-mopped twice to remove the sand and grindings and allowed to
air dry. The perception is that implementing this methodology costs more, emits more fibers, takes more time, and is generally more difficult.

Data
Process description: Thirteen braiding machines were using asbestos yarn during the survey. The construction of asbestos braid may be classified into two major classifications - the
filler and the cover. The braid filler contains five ends of asbestos yarn and seven ends of fiberglass yarn. The twelve yarns are intertwined and covered with
sixteen ends of fiberglass yarn. The purpose for intermingling and intertwining of the yarns is to produce a strong braid . A braid operator keeps the braiding
machine operating and replaces consumed yarn with new yarn bobbins. The braid from the machine is fed to a holding spool . Braid spools from the braiding
machine are further processed in the spooling room. In the hand spooling operation, which requires one operator, the braid is examined for defects and measured
as it is transferred from one spool to another. Should a defect be detected the segment is removed . Both the braiding and spooling are continuous operations.
However, asbestos yarn is used only on special orders. [PDF Pg. 2]

Process description:
Throughput:
Chemical concentration:
over 40,000 tons of inorganic fibrous insulation containing asbestos used in 1970
There are two principal methods of applying sprayed mineral fiber. In the dry method, dry materilal is dumped from a paper shipping bag into a large hopper,
where the material is agitated and subsequently blown into a 2- or 4-inch hose (Figure 1). The hose conveys the dry material to a nozzle at the actual site of
application (Figure 2). As the dry material leaves the nozzle, it passes through the focus of a ring of fine water jets. Mixing takes place at this focal point, which is
usually 4 to 8 inches from the end of the nozzle. The operator is able to control the air, material, and water mix, with valves at the nozzle. The wet method differs
in that the material is premixed with water in the hopper, and the resulting slurry is pumped to the nozzle and sprayed upon the surface to be coated. The nozzle
used is similar to that used to apply plaster.
"A thirty-story building may use 200 tons, while the World Trade Center complex being built for the New York Port Authority will use 5000 tons on the twin 1
10-story towers (above the fortieth floor, only non-asbestos-containing spray materials were used). The sixty-story Chase Manhattan Bank Building is fireproofed
with 1,500,000 square feet of sprayed mineral fiber""; ""The Holland-American ocean liner Rotterdam contains 400,000 square feet of sprayed mineral fiber used
for fire protection, thermal insulation, and sound and condensation control".
"material used for fireproofing in building construction usually is a blend of 5 to 30% asbestos fiber (chrysotile), mineral wool, clay binders (as bentonite),
adhesives, synthetic resins, and other proprietary agents such as oils"; "materials used for thermal insulation on turbines contain nearly 100% asbestos fiber (often
amosite or amosite and crocidolite) plus the usual binders and adhesives"; "material used for acoustical and decorative purposes may contain a greater percentage
of mineral wool and little or no asbestos fiber"; "Some materials are applied as a sprayed slurry (commonly known as cementitious spray) and will often contain
vermiculite, gypsum, and shorter asbestos fibers"

Production, import, or use volume: Most chrysotile and all amosite asbestos fibers were imported. (Virta Undated) U.S. production of asbestos fiber never supplied more than about 20% of the
nation's total asbestos demandsand the best grades needed for fabrication of most insulation products came from elsewhere (p. 5)In the year 2000, however,
15,000 metric tons were consumed (p. 10)
Life cycle description: Table 1 - in 1972 the following materials contained asbestos: Molded block, tape, cement, paper, cloth, and board
Throughput: Each WWII USS Fletcher class destroyer bore nearly 30 long tons of thermal insulation on her pipes and machinery. The next-generation, USS Gearing class,
carried just over 24 long tons pership despite having the identical power plant as Fletcher because more efficient and lighter materials became available. At the
extreme, the USS Iowa class battleships carried nearly 465 longtons of thermal insulation. Ships intermediate in size between destroyers and battleships carried
intermediate amounts of the material, (p. 2)Amosite was 86% of the asbestos used (p. 3)The quantity of insulation in Navy ships of the 1970's ranged from about
three long tons in a tugboat, about long 39 tons in a new DDG, and about 55 long tons in a nuclear powered cruiser (p. 10)
Chemical concentration: Except for the lowest value in Figure 1 (1943, 59%), the weight percent of asbestos or asbestos-containing insulation varied between 80% and 99% (p. 4)

Number of sites:
Switching on the ventilation system in a commercial building can re-entrain fibers that settle out in still air. In addition, heavy occupant traffic in a building can
re-entrain asbestos fibers that have settled to the floor when the building was unoccupied. Roof leaks or plumbing leaks can weaken the water-soluble adhesive
used with most spray applied ceiling insulation, causing it to become friable, loosen and in severe cases drop off the ceiling in large clumps. High humidity can
also loosen asbestos insulation or make it friable. (3/6)

Chemical concentration: Recently it has been revealed that shipments of "amosite" to the United States and Canada never stopped and that "amosite" started containing ever larger
quantities of silica and crocidolite, suggesting that crocidolite was blended with amosite, thelethal mixture being sold as "amosite. " The industrial practice of
mixing crocidolite into amosite became the more heinous after Wagner, Sleggs, and Marchand published their data on the facility with which crocidolite inhalation
leads to malignant mesothelioma. Later it was revealed that in the United States amosite (and, in view of the foregoing considerations, potentially crocidolite as
well) was being incorporated into building products such as wallboard, spackling, ceiling tiles, and pipe insulation, (p. 6)A cubic millimeter of chrysotile asbestos
potentially can release into the ambient air between 25 and 250 billion asbestos fibers of effective size range (10 by 0.02 micrometers) for pathogenic action

referring to.Estimated in Germany there are 10A9 mA2 asbestos cement products and 10A10 mA2 asbestos cement products in West Europe. (Page 2).
Asbestos cement prodcuts (i.e., roof tiles) contain up to 11-12% asbestos.The sizes for approximately 3E4 asbestos fibers were measured and evaluated from
roofing tiles during this investigation. The measured and analyzed mineral fibers consist of 30% chrysotile and 25% amphiboles.

Process description: Inform workers who will remove the flooring, employer of employees working in the area and the building owner that Asbestos containing flooring has been
identified.Demarcate the identified regulated area with signage.Vacuum the entire flooring using a HEPA vacuumseparate carpet from tile underlayment (if
needed) If possible removal the whole flooring: wood underlayment and flooring. This can be accomplished by cleaning the whole area with a HEPA vacuum
and wet the surface with a mixture of water and detergent. Remove a 4-8 inch strip by one wall to identify the underlayment joints. Next, make a series of 4-8
inch wide strips cented over the underlayment joints. Continue for the entire floor. Pry up a corner of the strip farthest from the entrance - separating the backing
from the wear surface. Remove and store each strip for disposal. Pry up individually tilesHeat can be used to loosen the adhesive followed by hand scraping
under damp conditions. Start on the less trafficked area by carefully wedging the scraper in the seam of two adjoining tiles and gradually forcing the edge of one
tile up and away. Continue with the next tile. Removed tiles are placed in a heavy-duty impermeable trash bad of leak tight container. It the tile will not come
up apply heat to loosen the adhesive. It is possible to heat larger areas of flooring time using a hot air gun or infrared heat machine.Water with detergent can be
applied to remove asphaltic cut back adhesives. Moisten an area 3ft by 10 ft. wet scrape with a stiff bladed wall or floor scraper. Place loosen adhesives in a leak
proof container. To completely remove any remaining cutback adhesive, create a slurry of sand, water and detergent. Apply the slurry in 6 ft by 6 ft sections.
Use a terrazzo floor machine to the section that the slurry was applied. Clean edge of room using a rubbing stone. Collect the wet used sand and adhesive and
store in leak proof container for disposal. Alternatively, a floor buffing machined with floor stripping solution can be used to remove remaining adhesive. Apply a
ethanolamine stripper to a 6 ft by 6 ft area. Allow 5 minutes to soak. Remove using a floor cleaning machine equipped with a 3M black floor pad. Areas around
the edges can be addressed by using a hand held piece of the black flooring pad. Collect the waste adhesive and store in leak proof container for disposal.Sheet
flooring removal is accomplished by slicing the vinyl flooring in 4-8 inch strips, peeling and rolling the wear layer while wetting the nip point with liquid detergent
solution and scraping the residual backing. Dispose of strip in a leak proof container an repeat process. This will leave the flooring felt which can be removed by
wet scrapping using a stiff-bladed scraper. Put the wet sections of felt in the leak proof container.The processes is similar for loose lay and peripherally adhered
sheet flooring except that the strips can be 18 inches wide.Once all the flooring and adhesives have been removed, the site is vacuumed with a HEPA vacuum.The
underlayment boards can now be removed by loosening the boards using a hammer and chisel. To pry up the underlayment. Moisten the surface through out
the process. Each removed section should be quickly wrapped in 6 mil plastic sheeting and disposed. Vacuum remaining subflooring. Label waste for disposal
"Danger. Contains asbestos fibers. Avoid creating dust. Cancer and lung disease hazard." And send to an approved land fill.

Data
Process description: The asbestos workers slice the length of the pipe's coating longitudinally at the 12:00 position with a razor knife. The coating is sprayed with water, then the
heater is turned on. After heating for 30-60 seconds, there is visual indication (shriveling, drooping or even falling to the ground) that the coating is detached from
the pipe's primed surface. The crew begins manually peeling the coating off. A rubber-tired front end loader with a clamping fork lifts the asbestos-free pipe and
stacks it in the clean pipe area.The asbestos crew gathers the "sheets" of coal tar coating and asbestos wrap from the concrete floor and places them in a bladder
bag-lined rolloff box. Once or more each working day the concrete surface is wetted, cleaned and the water is drawn up, filtered and discharged.Asbestos crews
periodically inspect the ground around all stackedpipe, machinery pathways, pipe staging and cleaning areas for loose coating fragments. When found, fragments
are picked up, bagged and disposed. [PDF Pg. 3]
Throughput: The heat method, as described, removed the asbestos-containing coating from 17 miles of pipe in 68 calendar days without regulatory compliance (asbestos &
opacity inspections) problems, damage or injury incidents or public complaints at a cost of approximately $4.30 per foot. [PDF Pg. 3]

Life cycle description: A difficulty with introducing health-risk concepts into life cycle assessment (LCA) is the pulse-flux problem, which is discussed in the article. Figure 1 (pg
81) presents the inventory analysis and impact assessment in LCA. In this study the authors focussed on asbestos, which is a hazardous substance, particularly
in its disposal stage, and estimated health risks as well as energy consumption. They conducted an estimation of asbestos emission and energy consumption as
an inventory analysis, and converted asbestos emissions into health risks as an impact assessment. At the same time, the authors discuss a way to resolve the
pulse-flux problem, which is a difficulty when taking hazardous substances into account in LCA. In this paper, the authors do not weight health risk and energy
consumption (pg 81). The results for life-cycle energy consumption are shown in Table 3 (pg 87). Regarding the difference between scenarios in the disposal stage,
the melting requires 17.1Gcal of energy, while the packaging/landfilling requires only 0.254 Gcal. However, when the authors considered the life-cycle energy
consumption of sprayed-on asbestos, it was estimated that the use of asbestos conserved several hundred gigacalories of energy, based on the assumptions given,
owing to its huge insulating effect in the use stage. Such energy conservation greatly exceeded the energy consumption required for melting, and the life-cycle
energy consumption was found to be hardly affected by the selection of scenarios (pg 86).

Comments: In 2006 and 2007 the Environmental Protection Agency (EPA) conducted three tests to examine the cost and environmental effectiveness of Alternative Asbestos
Control Method (AACM). Two tests were conducted in Fort Chafee, Arkansas and one was conducted in Forth Worth, Texas. The EPA discontinued testing the
AACM due to technical deficiencies. The AACM remains unapproved and should not be used.

Process description: To refinish asbestos containing tiles, first dry sweep the stripped floor to remove any settled debris. Apply polish from a mop bucket and wring the mop out
until slowly dripping. Using a cotton string mop, apply the wax as evenly as possible, covering about 100 square feet per 24 ounce mop head. Let each coat dry
thoroughly before the next application, typically 20-30 minutes. Apply two uniform coats of polish. (50/71) To strip the tiles, sweep the floors, mix stripping
solution in a bucket of water, apply generously and allow to stand for 5 minutes. Double scrub the floor with a black pad. Use a second bucket and mop to pickup
the spent stripper solution. Rinse the floor and remove all residue twice. Repeat as necessary. (51/71)

[PDF Pg. 2]Two experiments were conducted each day of the study. Each combination of cleaning method and contamination level was tested twice in each test
room. A single experiment consisted of contaminating a new piece of carpet (approximately 500 ft2} with asbestos fibers, collecting work-area air samples, col-
lecting microvacuum and bulk carpet samples, dry-vacuuming or wet cleaning the carpet while collecting a second set of work-area air samples, collecting a second
set of microvacuum ,and bulkcarpet samples, removing the carpet, and decontaminating the test room. Each test room was decontaminated by encapsulating the
carpet and the polyethylene sheeting on the ceiling and walls before their removal. These materials were removed and replaced after each experiment.Experimental
procedures for this second set of experiments were identical to those in the first 16 except that the carpet was dry vacuumed, wet-cleaned, and then dry vacuumed
again when dry. The same test area was also used; however, the two 500- ft2 test rooms were converted to four 160-ft2 test rooms, each with dimensions of
approximately 8 x 20 ft.

Process description: removal and replacement of asbestos-cement pipeRemoval of A/C pipe while replacing it with non-asbestos materials; converts friable ACM, and ACM that may
become friable when disturbed into nonfriable ACM during the replacement process; and uses amended water to achieve adequate wetting of all ACM.When
a facility component that contains, is covered with, or is coated with RACM is being removed from a facility as a unit or insections (e.g., a pipeline), the rule
requires adequate wetting of all RACM exposed during cutting or disjoining operations; and each unit or section to be carefully lowered to the floor and/orground
level, not dropping, throwing, sliding, or otherwise damaging or disturbing the RACM. After a facility component (e.g., pipeline section) containing, covered
with, or coated with RACM has been taken out of the facility as a unit or in sections pursuant to paragraph (c)(2), it shall be stripped or contained in leak-tight
wrapping.8 If stripped, the owner/operator may either adequately wet the RACM during stripping; or use a local exhaust ventilation and collection system designed
and operated to capture the particulate asbestos material produced by the stripping, and this system must exhibit no VE to the outside air, or be designed and
operated in accordance with 40 CFR 61.152 (air cleaning).The accepted technique to remove and replace A/C pipes is known as "open trench replacement."
In open trench replacement, the pipe is located, cleaned, and inspected. Because pipes run beneath and cross transportation corridors, traffic is rerouted to
availabledetours. Temporary water and sewer service is installed to handle the water supply and/or wastewater handling affected by the disruption of service.
Other utilities (electricity, cable, opticalfiber) that may obstruct or interfere with pipe replacement are also identified. Once the location of the pipe and all utilities
are identified, the road surfacing, and other structures, such assidewalks, medians, etc., are removed and an open trench is dug to expose the length of pipe to be
replaced. A pipe cutter is clamped around the A/C pipe being replaced, and it is scored along the outside of its circumference while water is applied to prevent
emissions of asbestos to the atmosphere, which may occur along the line of cutting. The pipe is snapped along the cut and the process is repeated to produce
transportable 6- to 8-foot sections of pipe. Asbestos cement pipe in poor condition may resemble wet cardboard in the way it responds to these removal activities.
Itcan simply collapse and tear into smaller pieces, rather than snap, as A/C pipe in good condition is known to do. Each pipe section is removed, wrapped in
plastic, and placed on a truck labelled according to regulations for asbestos waste disposal.The "Close Tolerance Pipe Slurrification" (CTPS) method uses an
equipment train to deliver drilling fluids and clays in suspension through a pipe in the center of the train. The equipment train uses a cutting head which grinds the
underground A/C pipe to a fine grain while the fluids maintain the adequately wet requirements of 40 CFR 61.145 and entrain the finely ground pipe fragments
in a slurry. The proposed CTPS AWP is as follows:Prior to using the CTPS for an ACPRP, the owner/operator would conduct underground pipe inspections (e.g.,
by using remote technologies like robotic cameras) and shall identify, locate, andmark onto an underground utility map of the area all identified potential areas
of malfunctions, such as changes in pipe type, drops in the line, broken and offcenter points, and changes in soil type.l. Vertical Access PointsVertical access
points (e.g., manholes, trenches) are made at designated intervals along the length of pipe replacement. The distance between vertical access points is a function
of the soil type, pipe size, pneumatic pressure on the CTPS head, and frictional drag on the line; and is determined for each project on a case-by-case basis by
the owner/operator. Incorrect estimation ofthe vertical access point locations may result in a malfunction. The owner/operator must not disturb A/C pipe during
the digging out of these access points. Water and suction should be used to uncover as much of the A/C pipe as is needed to begin the CTPSprocess.2. Removal
of Pipe at Terminals and Vertical Access PointsAt the starting and terminal points, and at designated intervals along the length of pipe replacement, sections of
pipe are cut and removed at the vertical access points (i.e., manholes, trenches).The owner/operator must handle all sections of A/C pipe in accordance with 40
CFR 61.145 and 40 CFR 61.150 of theAsbestos NESHAP.3. CTPS Equipment Train The CTPS technique should use a drilling head train with a slightly larger
diameter than the pipe being replaced. This technology must use a heavy duty four-stage cutting and wetting train, made of hardened carbon steel, which is able
to be fed directly around the pipe to be replaced. The cutting head must be drawn around the existing pipe and must be capable of grinding the old A/C pipe to a
fine powder using a liquid delivery system as described in sectionThe process must return the A/C pipe to a cementitious slurry that is a homogenous mixture and
stays adequately wet through disposal according to the requirements of 40 CFR 61.145. The owner/operator must ensure that the CTPS train pulls the replacement
pipe behind it, and that no ACM contacts the inside of the new pipe.4. Liquid Delivery The horizontal drilling train must be equipped with ports to deliver liquid
materials to the drilling head. Drilling fluids and bentonite clay should also be delivered through these ports to reduce frictional drag on the line, and to lubricate
the interface along the soil to pipe line.5. Trackable PipelineThe owner/operator would be required to ensure that the new pipeline is trackable by steel cable
(or other durable trackable material) laid withRflSSeWjJ^teSif §Mny CharacteristicsThe owner/operator would be required to ensure that no visibleemissions are

Life cycle description: Vermiculite is produced from mined ore and is used in agricultural and horticultural products as well as in insulation and construction applications.
Chemical concentration: The Agency purchased and began testing a limited number of vermiculite products available in garden stores in the Seattle area to determine if they were
contaminated with asbestos. Sixteen products were tested using widely-recognized standard protocols and asbestos was detected in five of them. However,
only three of these contained enough asbestos to allow EPA to quantify the percentage of asbestos reliably.PRODUCT ANALYSIS (see Table l)Therm-0-Rock
(~0.33%)Zonolite Chemical Packaging Vermiculite (~1.88%)Coles Cactus Mix (-0.45%)
Comments: Therm-O-Rock and Coles Cactus Mix come from the W.R. Grace Mine in Enoree, SC where there are active vermiculite mines. However, Zonolite Chemical
Packaging Vermiculite came from Libby, and it is expected that all product from Libby has been used at this point. Therefore, we will only consider Therm-O-Rock
and Coles Cactus Mix for purposes of investigation of Lawn & Garden Care Products containing vermiculite.

Production, import, or use volume: ASBESTOS:In 2016, U.S. consumption of asbestos was estimated to be about 340 tons, essentially unchanged from that of 2015 (likely all chloralkali industry).
An unknown quantity of asbestos was imported within manufactured products, possibly including brake linings and pads, building materials, gaskets, millboard,
and yarn and thread, among others, (p. 32/206)TALC:Three companies operated five talc-producing mines in three States during 2016, and domestic production
of crude talc was estimated to have decreased by 4% to 660,000 tons valued at $19.1 million. Montana was the leading producer State, followed by Texas and
Vermont. One company in Virginia that mines soapstone for dimension stone purposes had previously been included in the domestic talc data but was removed
beginning in 2014. Total sales (domestic and export) of talc by U.S. producers were estimated to be 545,000 tons valued at $97.5 million, a slight decline from
those in 2015. Talc produced and sold in the United States was used in ceramics (including automotive catalytic converters) (26%), paper (18%), paint (17%),
unclassified end uses (13%), plastics (12%), roofing (7%), rubber (4%), and cosmetics (3%). Of the estimated 385,000 tons of talc that was imported in 2016,
it is likely that more than 75% was used in cosmetics, paint, and plastics applications. Including imported talc, the U.S. end-use rankings were thought to be, in
decreasing order by tonnage, plastics, ceramics, paint, paper, roofing, rubber, cosmetics, and other, (p.168/206)

Production, import, or use volume: In 1979, the United States' consumption of asbestos amounted to 560,000 metric tons. By 1983, the annual total consumption had dropped to 217,000 tons. (3/4)
Life cycle description: Sprayed or trowelled-on materials used on ceilings or walls: This surfacing material is found as a white, popcorn textured decorative, acoustical, and fire proofing
cover in homes, buildings, and schools. TSI: Here asbestos is often found as plaster cement wrap around boilers, on water and steampipe elbows, tees, fittings,
and pipe runs. Asbestos is also found on duct systems, and as acardboard type of material (called aircell) found on steam pipe runs.Miscellaneous material: This
includes all materials containing asbestos which were not included in the above groups. For example: floor tile, sheet rock, ceiling tiles, automotive friction
products, rubber tile matting, rubber stair treading and risers, auditorium acoustical panels and sound proofing, gasket material, stage curtains, roofing materials,
transite siding, caulking, cement pipe, kiln insulation, electrical panel insulation and wiring, fire brick, tar, and others. (3/4)
Number of sites: In a survey of 3.6 million public and commercial buildings, friable asbestos was found in 733,000 buildings (20%). Sprayed or trowelled-on ACM was present in
192,000 buildings (5%). Thermal System Insulation (TSI) was found in 563,000 buildings (16%). 501,000 buildings (14%) contained damaged ACM. 184,000

Data
Production, import, or use volume: Annual world production of asbestos peaked at over 5 million tonnes in the mid-1970s but has since declined to a current level of about 3 million tonnes... The
asbestos-cement industry is by far the largest user of chrysotile fibres, accounting for about 85% of all use. (pg 24)More production data (general, not COU
specific; basically mining) on pg 46-48; product-specific data for 1977, '84, and'91 in Table 2 (pg 49)Asbestos-cement production facilities exist in more than
lOOcountries and produce 27 to 30 million tonnes annually (pg 49)Although declining in the North American and Western European markets, asbestos-cement
product manufacturing continues to grow in South America, South-East Asia, the eastern Mediterranean region and eastern Europe (Pigg, 1994). Japan, Thailand,
Malaysia, Korea and Taiwan imported 430 000 tonnes, well over 30%o of world-wide imports in 1989 (pg 50)
Life cycle description: There are five major asbestos-cement products: (a) corrugated sheets; (b) flat sheets and building boards; (c) slates; (d) moulded goods, including low-pressure
pipes; and (e) high-pressure water pipes (pg 49)
Chemical concentration: Asbestos-cement products contain 10-15% of asbestos, mostly chrysotile, although limited amounts of crocidolite have been used in large diameter, high-pressure
pipes, (pg 49)

Parameter Data
Throughput: The refinery historically operated 24 h/d and processed about 36,000 barrels/d of crude oil in 1920, 112,000 barrels/d in 1940, 220,000 barrels/d in 1960, and
365,000 barrels/d since the 1970s.
Chemical concentration: Based on a review of company records and discussions with professionals at the refinery, approximately 60% of the piping systems and vessels at the facility
were insulated over time (seeTable 1). Of that 60%, approximately 15% were in "cold" service, 25% in "hot" service (at least 280° F), and 20% in "very hot"
service (at least 800°F). Prior to 1975, the predominant forms ofinsulation in use at the refinery included ceramic fiber, fiberglass, mineral and rock wool, rubber
and foam, and asbestos containing insulation (calcium silicate and magnesium carbonate).The asbestos-containing insulation was predominantly used for "very
hot" service, and to a lesser extent for "hot" service. A relatively small amount of asbestos-containing insulation was also likely used for "cold" service prior to
1960. The calcium silicate and magnesium carbonate insulation used in these applications typically contained about 5-20% chrysotile, amosite or a blend of the
two asbestos, with some brands containing as much as 30% or more chrysotile or amosite. For example, amosite was used extensively in 85% Mag (magnesium
carbonate) and several brands of calcium silicate insulation) that were historically widely used in various industries including petroleum refineries.Beginning in
1972, asbestos-free insulation products had become available for "hot" and "very hot" insulation applications at the refinery. By 1974, these substitute products
were used forall new construction projects and for insulation replaced during maintenance and turnaround activities.

Process description: Devise a means of handling and removing nonfriable asbestosmaterial to control the release of fibers and keep breakage toa minimum.Mist the materials being
removed with a water spray toprevent fibers from becoming airborne. To enhance the effectiveness of the spray, the water should be treated with a chemical
wetting agent. Figure 5.2 shows an example of this.Use plastic or polyethylene (some type of synthetic membrane)to collect errant pieces of material dislodged
duringremoval; for example, use plastic sheeting around the perimeterof a house during siding removal.Package the asbestos waste material as soon as possible
anddo not leave it unattended or open to the public.Wear a disposable Tyvek suit, gloves, and a half-mask respiratorwith high-efficiency particulate air (HEPA)
filters while removing, packaging, and disposing of the asbestos waste material. It should be noted that it is required to seek a medical opinion before wearing a
respirator, which places an additional strain on the heart and lungs.Generate a Waste Shipment Record (WSR). This information/form is required prior to disposal
