Glossary of Environmentally Preferable Purchasing Terms
Acids ^ w - Solutions with a pH range between 0 to 6.9. They are corrosive between pH
0 and 2.0 and produce severe burns on contact. See also pH.
Uses: Many cleaning products (e.g., delimers, bathroom cleaners, bowl cleaners) are acidic.

Acute health effects - Effects which occur rapidly as a result of short-term (usually less
than 24 hours) exposures. Acute effects are usually of short duration, but long-term
effects can occur after one exposure. Examples include irritation, corrosivity, chemically
induced unconsciousness (narcosis), or death.

Acute toxicity - The potential of a chemical substance to cause adverse health effects
from short-term exposure.
Aerosol propellents - Gases used to pressurize spay products. Chlorof luorocarbons
which deplete the ozone layer, may be found in old cleaning products. Today other
chemicals, such as isobutene, a petroleum product may be used. Hydrocarbon propellents
like isobutene contribute to smog problems because of their contribution to tropospheric
(ground level) ozone formation.

IQs
Alkalies u w (bases) - Solutions with a pH range between 7.1 to 14.0. An alkali is
corrosive when pH is higher than 11.5. See also pH.
Uses: Many cleaning products (e.g., bleach, detergents, dishwashing soaps, drain openers
and oven cleaners) are alkalies.

Ambient air pollutants - Pollutants for which ambient air quality standards have been
developed. These pollutants include nitrogen oxides, sulfur dioxide, ozone precursors,
particulate matter, carbon monoxide, and lead.
Bioaccumulate u W - The process where chemicals are collected and stored in plant and
animal tissue. Some products may contain ingredients that will be taken up by smaller
aquatic plants and animals and increase in concentration through the food chain as these
plants and animals are consumed by larger animals.

Biobased product - Commercial or industrial products (other than food or feed) that
utilize biological products or renewable, domestic, agricultural (plant, animal and marine),

-------
or forestry materials.

Biodegradable - The ability of a substance, material or product ingredient to readily
decompose under natural conditions by the action of microbes.

Biological oxygen demand (BOD) - Refers to increase use of oxygen by microorganisms in
surface water when they metabolize organic chemicals. The total BOD load in an aquatic
ecosystem is an important water quality parameter because this increased use of oxygen
reduces amounts available to aquatic organisms like fish. At the same time, it is important
to note that the availability of carbon sources (essentially what BOD measures) is often
not the primary limiting factor in the growth of microorganisms in an aquatic ecosystem.
In many aquatic ecosystems, other nutrients grow and it is the additional loading of these
nutrients, rather than carbon, that is the primary factor in excessive microbial growth and
oxygen depletion.

Carcinogen - Chemical capable of causing cancer.

Cardiac sensitizer - Chemical which, upon repeated exposure, can in some persons cause
the heart to become sensitive to the stimulant properties of epinephrine (which is
produced by the body's adrenal glands). Subsequent exposure to the sensitizer may cause
fatal cardiac arrhythmias. Some chlorinated solvents are sensitizers.

CAS number - Chemical Abstract System number. A unique number used to identify each
chemical.

Central nervous system depressant - Chemical toxic to neurons in the brain. With
increasing acute exposure, CMS depressants cause headache, dizziness, confusion
euphoria, drowsiness, loss of consciousness and death through inhibition of breathing.
Chronic exposure may cause tremors, personality changes, visual impairment, and loss of
hearing, memory, or intellectual capacity. Many organic solvents are CMS depressants.

Chronic health effects - Effects which generally occur as a result of long-term exposure,
and are long duration. Examples include cancer, liver damage and chronic bronchitis.

Chronic toxicity - A chemical that is toxic over continual/repeated exposure.

Combustible - A substance having a flash point at or above 100° Fahrenheit up to and
including 150° Fahrenheit, according to the Consumer Product Safety Commission. The
Occupational Safety and Health Administration defines a combustible liquid as having a

-------
flashpoint at or above 100° Fahrenheit but below 200° Fahrenheit.

Corrosive - Chemical which, upon contact can cause deep tissue damage, such as burns to
eyes or skin.

Dyes - (Includes azo, basic disperse, fiber-reactive, vat dyes and fluorescent agents) May
cause allergic reactions.
Uses: As colorants or whitening agents in many products, including all-purpose cleaners,
disinfectants, fabric softeners.

Flammable - A substance having a flashpoint above 20° and below 100° Fahrenheit,
according to the Consumer Product Safety Commission. An extremely flammable
substance has a flashpoint at or below 20° Fahrenheit.
Flashpoint uW - Lowest temperature for sufficient vapor to form in the presence of
oxygen to permit ignition.

Fragrances - Any of 4,000 chemicals. May cause skin irritation, discoloration, rashes or
allergic reactions. May be irritating to the eyes and respiratory tract.
Uses: Many cleaning products, either to simulate the smell of "fresh air", flowers, etc., or
to mask odors of other chemicals in the product.

IP
Hazardous ingredient - Toxic, corrosive, ignitable, or reactive ingredient u*
Incompatible u w - Chemicals which are incompatible react violently or produce toxic
byproducts.

Irritation - Redness, swelling or tissue damage caused by chemicals. The degree of
irritation is dependent on dose. Chemical irritation may result in mild skin itching, or fatal
damage to the lungs.

LC50/Lethal concentration - A measure of acute toxicity. The lethal concentration that
if inhaled will kill half of a group of organisms in an experiment in a given time. In EPA's
Toxic Substances Control Act program, a chronic LC50 or Ec50 <0.1 mg/L is highly toxic;
and a chronic LC50 or EC50 > 10 mg/L is a low toxicity.

LD50/Lethal dose - A measure of acute toxicity. The lethal dose that will kill 50% of lab

-------
animals exposed to it orally or through the skin. The lower the LD50, the more toxic the
compound.

Mutagen - A chemical that can alter genetic material in humans.

Organic chemical - A chemical which contains carbon. Chemicals which do not contain
carbon are termed "inorganic".

Oxidizer (oxidizing agent) - A chemical capable of reacting with other chemicals in an
"oxidation" reaction. Chemical reactions involving strong oxidizers may release heat or be
explosive.
Ozone depletion u w - Destruction of the stratospheric ozone layer which shields the
earth from ultraviolet radiation harmful to life. This destruction of ozone is caused by
the breakdown of certain chlorine and/or bromine containing compounds
(chlorof luorocarbons or halons), which break down when they reach the stratosphere and
then catalytically destroy ozone molecules.
pH ^ w - A measure of the acidity or alkalinity of a solution. A pH of 7 is considered
neutral. A pH greater than 7 indicates alkalinity. A pH less than 7 indicates acidity. In
the absence of specific test data on irritation, pH provides some insight into whether a
product will be corrosive or cause irritation. Products with very high or very low pH (11.5
or 2) should be assumed to be corrosive. High or low pH values (e.g., between 9 and 11, or
between 4 and 2) indicate the product would be more irritating than neutral pH products
where the pH is closer to 7.

Sensitizer - A chemical that causes a substantial proportion of exposed people or animals
to develop an allergic reaction after repeated exposure to the chemical.

Solvent - Liquid used to dissolve other substances. Aqueous solvents consist primarily of
water, while organic solvents can include a variety of organic chemicals such as acetone,
benzene, toluene, ethyl acetate, xylene and turpentine. Most organic solvents are Volatile
Organic Compounds (VOCs) that contribute to smog problems because of their
contribution to tropospheric (ground level) ozone formation.

Teratogen - A chemical that causes malformation in the fetus and/or birth defects in
humans.

-------
IP'
Volatile Organic Compounds (VOCs) ^ w - In this context, VOC means any organic
compound (carbon containing) which has a vapor pressure of greater than 0.1 mm Hg or, if
the vapor pressure is unknown, has 12 or fewer carbon atoms. VOCs in cleaning products
are of potential concern because of indoor air exposures to office workers and others.
They are also of concern because they contribute to the formation of smog in outdoor air.
Some chemicals considered VOCs include acetone, benzene, perchloroethylene, among
many others.

1.0   History of Environmentally Preferable Purchasing (EPP)
Environmentally Preferable Purchasing (EPP) was first introduced in 1993 when President
Clinton signed Executive Order (EO) 12873, Federal Acquisition, Recycling, and Waste
Prevention. In 1998, President Clinton signed EO 13101, Greening the Government Through
Waste Prevention, Recycling, and Federal Acquisition, which superseded the previous EO.
However, it did retain similar requirements for the U.S. Environmental Protection Agency
(EPA) to develop guidance to address environmentally preferable purchasing. EPA
subsequently developed a Final Guidance on Environmentally Preferable Purchasing
(www.epa.qov/opptintr/epp/finalquidancetoc.htmy EPA's final guidance document was
designed to help federal agencies comply with President Clinton's EO 13101.

1.1   What is  Environmentally Preferable Purchasing?
The federal government defines environmentally preferable purchasing, or EPP as it is
more commonly known, as "...products or services that have a lesser or reduced effect on
human health and the environment when compared with competing products or services
that serve the same purpose.  This comparison may consider raw materials acquisition,
production, manufacturing, packaging, distribution, reuse, operation, maintenance, or
disposal of the product or service."

What this really means is the goal of an EPP program is to get purchasers to select
products that have a reduced effect on human health and the environment, when compared
to other competitive products. Purchasers should consider the life cycle of the product.
A product's life cycle considers all aspects of the product such as purchasing of raw
material, manufacturing, packaging and distribution, use, and finally, disposal.

-------
Environmentally preferable products can include items such as:
   •   Recycled content products              •  Water conserving products
   •   Less toxic products                     •  Biodegradable products
   •   Products with less packaging

1.2    Does Our School Have to Use  EPP?
Although Kentucky does require that schools implement recycling, as long as it is
economically feasible, there are no state requirements or federal requirements for schools
to implement the EPP program.

The goal of this training manual and  the accompanying training is to help schools develop
their own EPP Program. Although EPP can and does focus on many types of different
products, the goal of this training focuses on identifying EPP products with respect to
janitorial cleaning supplies.  After this training is completed, it will be up to the individual
schools to decide if they want to implement EPP.

1.3    Who are  KPPC and SAR?
The Kentucky Pollution Prevention Center (KPPC) was established in 1994 through a
Kentucky legislative mandate. KPPC  serves as the state's resource for pollution prevention
(P2) technical assistance to Kentucky industries, businesses, schools, and many other
organizations.  KPPC is located within the Speed Scientific School at the University of
Louisville, but is responsible for working with organizations throughout the Commonwealth.
Many of KPPC's services are free, non-regulatory, and confidential.

-------
SAR is a non-profit organization that was established in 1997. SAR focuses on promoting
environmental awareness and recycling among schools located in eastern Kentucky.
Initially, SAR worked with just a few schools in only a few counties, however their region
eventually grew to over 205 schools representing nearly 21 counties.

KPPC and SAR understand the importance of environmental stewardship among our
communities.  The EPP program is an  important step towards a safer and cleaner
environment. It is our goal that this training manual will provide the foundation necessary
for your school to implement a successful EPP program.

2.0   Why Implement an EPP  Program?
Implementing an environmentally friendly purchasing program for janitorial cleaning
products is much more than simply "doing the right thing for the environment." Schools
today face many difficult and challenging issues, not the least of which is trying to ensure
that students learn in a clean and healthy environment. Children can spend up to eight
hours a day in the school building;  thus a healthy indoor environment is crucial. Just as
important however, is that faculty and staff also work in a healthy, clean environment.

Allergic reactions to "sick" indoor environments keep 10,000 American children out of
school each day. The Janitorial Products Pollution Prevention Project
(www.westp2net.orq/Janitorial/.ip4.htm), which was conducted in the San Francisco Bay
area, found that six percent of the cleaning products that were analyzed were "so
dangerous, that they should not be used" and an "additional 35 percent were dangerous,
but can be used successfully with extreme care." The project identified some of the most
dangerous products as acid toilet bowl cleaners; floor finish strippers; heavy-duty, high
strength degreasers; sewer drain openers, and oven cleaners.1

As part of this same study, an 18-month evaluation of janitors in Santa Clara County was
undertaken and found that the 27,000 janitors working in the county sustained
approximately 1,200 injuries annually, 20 percent of  which were mostly chemical burns to
the eyes or skin. A further review of just  25 percent of the county's janitors found that
1 www.westp2net.org/Janitorial/ip4.htm

-------
they used 400,000 pounds of hazardous materials annually in cleaning, or approximately 60
pounds a year per janitor.2


Based upon the statistics presented above, it is obvious that schools do face difficult
challenges in maintaining healthy buildings to all involved individuals - teachers, staff, and
students. However, if adopting an EPP program for janitorial products is beneficial to
schools, then why are more schools not taking advantage of this program? A summary
provided below helps identify advantages and disadvantages to such a program, and may
help your school overcome these obstacles in the future.


EPP Program for Janitorial Cleaning Products

^ Advantages

      ^    Creates a safer environment for students, faculty and staff;
      ^    May reduce the potential for concerns about chemical compatibility;

      ^    Environmental stewardship - "Lead the Charge".

                                                           =€
^ Disadvantages

      ^    It is new - people may not want to cooperate;
      ^    It is different - people are unsure of different ideas;
      ^    Change is often challenging and can be time consuming; and
      ^    Training will likely be necessary.

Remember, change is always difficult. But, it is important to stress to those directly
involved (janitorial cleaning staff, purchasing department, etc.) the benefits that these
individuals can enjoy.  As with anything, making sure that people from all departments
within the school are involved is extremely important to the success of your program.

3.0   Your EPP Team:  Who & Why
An environmental purchasing effort requires the involvement of a number of key players.
Facilitating communication and partnerships between these individuals and departments
will be key to the success of your school's effort.
                                Superintendent
       Director of Facilities
   Purchasing Personnel
                   Principal
Custodial Staff
3.1   Key Team Players
The Superintendent encourages widespread participation in the program by issuing a policy
statement or directive communicating the school district's commitment to EPP (some
sample policy statements are provided at the end of this chapter). Faculty and staff will
follow the lead once the climate of acceptance has been conveyed from the highest school
authority.
                                                                                7

-------
The Director of Facilities provides technical expertise to identify environmental and
health risks and helps to develop criteria and specifications for selecting safer products
that also meet performance standards. This position is ultimately responsible for final
product approval.

Purchasing Personnel develop product bid specifications, maintain a listing of acceptable
product alternatives and costs, and process orders.

The Principal'allows and encourages participation at the individual school, therefore,
setting the climate of acceptance for faculty and staff at a more direct level.

Custodial Staff identify product performance needs and use products. Custodial staff
input and participation is essential for success of the program.

3.2 Forge Partnership Between Facilities Director and Purchasing Department
An effective partnership between the facilities director and the purchasing department is
key. The two entities must work together to design the bid specifications to meet the
goal of the project while ensuring product performance. Purchasing personnel will rely on
the facilities director for technical input in the bid specifications.

3.3 Custodial Staff Input
As the ultimate end-user of the products, custodial staff involvement in the decision-
making process is critical to the success of the program. It is important to recognize and
utilize the expertise of the staff as the products are evaluated. Additionally, it will
increase the morale of custodians who recognize the school's concern for their health and
working conditions and who appreciate the opportunity to participate in making decisions
about their work.

Example EPP Policy Statements
1. The Douglass County School District is committed to providing a safe and healthy
environment for its faculty and students. To help achieve this, schools are encouraged to
implement an environmentally preferable purchasing (EPP) program for janitorial
cleaning products. Purchasing environmentally friendly cleaning products demonstrates
our goal to live and work in a cleaner environment.
2. The Douglass County School District is committed to minimizing the adverse
environmental impacts of its purchases through environmentally preferable purchasing
(EPP) for janitorial cleaning products. EPP not only protects the environment; but also
protects human health, thus ultimately improving the overall quality of the District's
school purchases by placing an increased value on the well being of its faculty, staff and
students.
3. The purchase and use of products and services can have a profound impact on the
environment. The Douglass County School District recognizes the positive impact that it
can make on the environment through the purchasing decisions that its employees make.
It is the intent of the District to integrate environmentally preferable purchasing (EPP)
considerations into purchases of janitorial cleaning products. Although the environment
may not be the core of our professional mission, the integration of these factors will
result in economic, health and environmental gains that will further our goals while
providing a safe and clean environment for our faculty, staff and students.

4.0 How to Implement an EPP Program
Implementing an EPP program will require time and effort from a variety of individuals.
Though it may seem like a huge task, large state governments like the State of
Massachusetts have developed their own successful EPP program. The implementation
process has been separated into a series of steps that will hopefully allow things to move
more smoothly.

4.1 Step One - Inventory Current Cleaning Products
A Product Inventory Sheet is included in Appendix A. This is used to identify the types
and quantities of products that your custodial staff is currently using. This basically
includes toilet bowl cleaners, floor cleaners, glass cleaners, etc. Remember, this program
only focuses on custodial cleaning products and does not look at other products outside of
this specific area.

In order to collect accurate product inventory information, you will want to interview your
purchasing personnel, custodial staff, and others that may have knowledge of your cleaning
products. It is important to talk to all groups; you may be temporarily out of stock of a
particular product and not know it unless you talk to all parties. Make sure you have
developed a complete list of all the cleaning products used.

4.2 Step Two - Identify Cleaning Product Ingredients & Safety Concerns
After you have fully inventoried your custodial cleaning products, you will then need to
identify the health and safety of each product. Remember, the purpose of implementing

-------
this EPP program is to find substitute cleaning products that have reduced effects on the
health of your people, and on the environment where they work.

There are two primary ways to evaluate the health and safety of your cleaning products;
use the material safety data sheet (MSDS) that should accompany each cleaning product
you use, or read the labels on each cleaning product. The MSDS provides more detailed
information and will be briefly discussed in this section, but a more thorough discussion of
an MSDS is presented in Appendix B.

An MSDS provides information about a particular product and hazards that may be
associated with that product. The federal Occupational Safety and Health Administration
(OSHA) mandate MSDS's. OSHA requires every company that manufactures or
distributes hazardous chemicals in the United States to prepare an MSDS. An MSDS must
provide a variety of fundamental information related to the chemical that will allow the
user to recognize and prepare for potential hazards associated with the chemical and
prepare for and react to emergency situations. It is required by law that employers
provide copies of MSDS's to employees that use those specific products.

OSHA requires specific elements that must be contained within all MSDS's. However, it
does not mandate the format this information is presented. Therefore, you will receive
MSDS's from different companies that will not look alike. Examples of several different
types of MSDS's are provided in Appendix C.
10

-------
At a minimum, OSHA requires that every MSDS contain the following information:

^ Chemical identity - The identity of the substance as it appears on the label.

^ Manufacturers name and contact information - Manufacturer's name, address,
telephone number and emergency telephone number. The date the MSDS was
prepared and an optional signature of the preparer.

^ Hazardous ingredients/identity information - Lists the hazardous components
by chemical identity and other common names. Includes OSHA Permissible
Exposure Limit (PEL), AC6IH Threshold Level Value (TLV) and other
recommended exposure limits. Percentage listing of the hazardous components
is optional.

^ Physical/chemical characteristics - Boiling point, vapor pressure, vapor density,
specific gravity, melting point, evaporation rate, solubility in water, physical
appearance and odor.

^ Fire and explosion hazard data - Flash point (and method used to determine it),
flammability limits, extinguishing media, special firefighting procedures, unusual
fire and explosion hazards.

^ Reactivity data - Stability, conditions to avoid, incompatibility (materials to
avoid), hazardous decomposition or byproducts, hazardous polymerization (and
conditions to avoid).

^ Health hazard data - Routes of entry (inhalation, skin, ingestion), health hazards
(acute = immediate and chronic = build up over time), carcinogenicity, signs and
symptoms of exposure, medical conditions generally aggravated by exposure,
emergency and first aid procedures.

^ Precautions for safe handling and use - Steps to be taken in case material is
released or spilled, waste disposal method, precautions to be taken in handling
or storage, other precautions.

^ Control measures - Respiratory protection, ventilation (local, mechanical
exhaust, special or other), protective gloves, eye protection, other protective
clothing or equipment, work/hygienic practices.
11

-------
Some MSDS's will have the National Fire Protection Association (NFPA) safety diamond.
The diamond is divided into four sections, each designated with a different color that
contains a number between 0 and 4; the lower the number, the less the hazard.  Each
section and color represents a different hazard:
         •  Red - Flammability;
         •  Blue - Health Hazard;    Blue —     J         2   / —  Yellow
         •  Yellow - Reactivity; and
         •  White - Special Hazards.      White  —

Additional information on the NFPA safety diamond is provided in Appendix D. The
Hazardous Materials Identification System (HMIS) can also be used to help identify
hazardous materials. The HMIS uses horizontal bars rather than a diamond and focuses
on worker exposure versus fire  hazards. The numbers for both models represent the
same level of hazard.  Additional information on the HMIS is also provided in Appendix D
                                                            Blue
                                                            Red
                                                            Yellow
                                                            White
Although MSDS's provide much good information, they can have errors, the data can be
incomplete, etc. - in short, they may not tell the whole story. That is why it is equally
important to look at the cleaning product labels, m  addition to the accompanying MSDS's.
Look for warnings on the labels such as CORROSIVE, CAUTION, WARNING, DAN6ER,
                                                                               12

-------
POISON, FLAMMABLE, COMBUSTIBLE, etc. If, after reviewing the MSDS and the
product label you are still unable to make a decision as to the safety of the product,
contact the product manufacturer, vendor, distributor, etc. and request additional
information.

4.3 Step Three - Listing Product Attributes
Identifying health and safety impacts of your cleaning products is not enough. You will
need to take the information that you learned (via the MSDS's, product labels, etc.) and
develop standards that you can compare your products against. Unfortunately, there are
no universal standards that have been established to determine if certain cleaning
products are environmentally preferable. However, some organizations have identified
"attributes" they consider when purchasing environmentally friendly cleaning products.
Several EPP projects have been implemented that focused on janitorial cleaning products.
These include a joint study conducted by the Government Services Administration (GSA)
and the EPA in 1993, and a second program implemented in the City of Santa Monica. Both
studies (among others) are included in Chapter 6 - EPP Case Studies and have identified
key environmental attributes that were considered when purchasing environmentally
friendly cleaning products. These attributes are presented below.

HI Skin/Eye Irritation - the potential for adverse reactions from skin/eye
exposure to the product.
HI Chronic health risks - the likely chronic health risks from skin and inhalation
exposure to the product.
03 Biodeqradability - toxic chemicals usually degrade to less toxic forms. The
faster a chemical degrades, the lower the exposure potential. As a rule of
thumb, for an "environmentally-preferable" product, more than half should
biodegrade within 28 days. The balance of the product should biodegrade
within a few months after its application.
13

-------
HI Carcinogens - products that contain known or suspected carcinogens (cancer
causing) should not be used.

HI Percentage of volatile organic compounds (VOCs") - VOCs are known to
contribute to smog formation and create health risks. Products that do not
contain VOCs in concentrations that exceed 10% of the weight of the product
are preferred.

03 Amount of product packaging - products with reduced packaging decrease the
volume of waste that must be disposed.

03 Presence of ozone depleters - ozone-depleting compounds should be minimized.
Click on this link, http://www.epa.gov/ozone/ods.html to view a list of ozone-
depleting substances provided by the U.S. EPA.

HI Potential exposure to the concentrated cleaning solution - the product
dispensing method should include safety precaution designs to minimize
exposure to the concentrated solution.

03 Flammability - non-flammable products are preferable.

03 Presence of fragrances and dyes - cosmetic additives can be considered
unnecessary additives that increase overall life-cycle impacts and that could
increase health and safety and ecological concerns.

03 Energy needs - products that work effectively in cold water reduce energy
consumption.

03 Presence of petroleum or hydrocarbons - petroleum or hydrocarbon chemicals
should be minimized whenever possible.

03 Corrosiveness - does the product have an unusually low or high pH? Water has a
pH of 7.0.

These attributes are not meant to be inclusive of all attributes that other organizations

have identified. However, they provide an excellent framework from which your school

can develop an environmentally friendly procurement program for janitorial cleaning
14

-------
products. Appendix E contains a blank EPP Selection Criteria Checklist with a list of
attributes that your school may want to use. For simplicity, the checklist does not include
all attributes listed in this chapter. Also included in Appendix E is a sample Selection
Criteria Checklist for a glass cleaner.

4.4 Step Four - Developing a Purchasing Policy/Bid Specifications
You must develop bid specifications for your potential vendors. This will take some time,
but the effort is well worth it. Develop the bid specifications so that they are clear and
easy to understand. It will require much less of your time in the long run if the
specifications are easy to read and very succinct. Your bid specifications will include the
same attributes you selected from the previous section.

To help you develop your own bid specifications, an example is included in Appendix F.
Although this may be more detailed than what you initially need, it should give you a good
start. It is probably a good idea to require product samples as part of your bid
specifications so you can test them at your school.

4.5 Step Five - Identifying Alternative Cleaners
Finding a list of vendors, let alone a list of alternative cleaners can be a time-consuming
project. It is best to start with your current vendor to see if they carry the products
that you are seeking. The next step is to search other vendors and find out the types of
products they may carry.

Your current vendor, along with others you may contact may not readily have the
information necessary to make your decisions. But, you are in the driver's seat, if they
want your business, they will do what is necessary. It will likely take time and patience.
15

-------
They are probably not accustomed to their customers asking for the kind of information
you need. Ask for MSDS's for the products you want. If these are not readily available,
request that they get this information from the manufacturers directly. They may not
want to go to this trouble. You can either try to find another vendor, or ask who the
manufacturer is and make a request for the MSDS's directly. Always ask for samples of
the products that you are interested in. Many vendors will want to visit your school to
demonstrate their product. Take them up on this. This will give you an opportunity to
meet them directly and determine if they are someone that you want to do business with.
Be sure to arrange their visit with your custodial staff. They will want to be there for the
product testing.

4.6 Step Six - Make the Switch!
You have come this far, now it is time to finish the job. You will want to establish a target
date when you would like to have your EPP program in place. Without a target date, it is
easy to get sidetracked, and before you know it, too much time has elapsed along with any
enthusiasm your school may have had. It is important to establish a realistic target date;
too short and you are sure to miss it, too long and folks may lose interest. There is no rule
of thumb here. You will have the best idea as to how long it will take your school to
implement the program.

Training will be absolutely necessary. Your new products may require a completely
different approach; therefore it will be necessary to arrange training for your custodial
staff. Ask the vendor that you have selected to provide training to use their product. If
they want your business, they will be happy to provide this training. Remember, this is
something new, so don't be alarmed if your staff is less than enthusiastic. It is important
to explain why you are changing the program, and stress the health benefits they can
16

-------
expect. Change for no reason will be met with frustration, lack of cooperation, and
ultimately may result in your program failing.

Don't forget that as you phase the program in, you will need to dispose of your old cleaning
products.  There are several options you have available:
       •   Donate them to other organizations that can use them;
       •   See if your vendor will take them (not very likely, but it won't hurt to ask); and
       •   Proper disposal - make sure you know the proper disposal  method for all of your
          old products!  Contact the Kentucky Division of Waste Management at 502-564-
          6716 with disposal questions.
Remember, you may have limited storage for your cleaning products, so it is best to try
and dispose of as many of your old cleaning products as possible, before your new,
environmentally friendly products arrive!
                                                                                  17

Chapter 5

5.0 Evaluate Your EPP Program's Success
In Spring 2002, KPPC will mail a follow-up survey to all schools associated with this grant.
The scope of the survey will address whether or not the schools implemented or
attempted to implement an EPP program based upon information received through the Buy
Clean training program conducted in October 2001. The survey will attempt to quantify
any changes the schools experienced based upon implementation.

Information obtained through the survey is crucial, as it will provide an idea of whether or
not this program is feasible to implement within the existing school structure. It will also
indicate whether the information provided in the training manual was sufficient to allow
schools to implement the program without additional technical oversight. Input from the
survey will be used in developing any future revisions to the manual.

Topics to be addressed in the survey include:
X A copy of the initial Product Inventory Sheet and EPP Selection Criteria Checklist
filled out by the school at the beginning of the process.
X A list of alternative products selected to be used and what original products each
replaced along with an updated EPP Selection Criteria Checklist.
^ Any cost factors associated with the change addressing whether new products
selected are more expensive or less expensive than existing products.
^ Staff acceptance and involvement in the project.
^ Overall school climate on implementing the program.
^ Any physical or environmental changes experienced since implementation.

6.0 EPP Case Studies
Three different EPP Case Studies focusing on janitorial cleaning products are covered in
this chapter. These include:
• City of Santa Monica:
• Yellowstone and Grand Teton National Parks: and
• Joint government Services Administration and EPA Project.
A brief discussion of each project is provided below:

6.1 City of Santa Monica
The City of Santa Monica, California has a population of 90,000 and generates more than
$520 million per year on tourism. In 1998, the city decided to replace their janitorial
cleaning products with more environmentally friendly substitutes. Through this project,
they were able to eliminate 3,200 pounds annually of hazardous materials by replacing 15
of 17 cleaning products with less toxic or nontoxic alternatives. In addition, they were
able to reduce their spending by five percent on custodial products.

6.2 Yellowstone and Grand Teton National Parks
Yellowstone and Grand Teton National Parks significantly reduced the toxicity of their
janitorial cleaning products. During the product inventory, 130 different cleaning products
were identified in use at Yellowstone; another 30 were found on shelves but were not
being used. Many of the products contained chemicals known to have significant health
impacts to workers. The parks chose to use the bid specifications that were first
developed by the City of Santa Monica. Important lessons learned during this project
included:
20

-------
         •   Early coordination with warehouse manager and purchasing departments;
         •   Identifying someone that will serve as the "champion" to push the project
             along; and
         •   Obtaining top management support that is regularly communicated.

6.3   GSA  and EPA Cleaning Products Pilot Project
A cooperative effort between the U.S. General Services Administration (GSA) and the
U.S. Environmental Protection Agency (EPA) was initiated to facilitate the purchase of
environmental preferable cleaning products. The joint GSA/EPA project team developed a
matrix that can be used to identify and compare commercial cleaning products with
reduced impacts to human health and the environment.
                                                                                21

8.1 Glossary of Environmentally Preferable Purchasing Terms

Acids - Solutions with a pH range between 0 to 6.9. They are corrosive between pH 0 and
2.0 and produce severe burns on contact. See also pH.
Uses: Many cleaning products (e.g., delimers, bathroom cleaners, bowl cleaners) are acidic.

Acute toxicity: The potential of a chemical substance to cause adverse health effects
from short-term exposure.

Aerosol propeHants - Gases used to pressurize spay products. Chlorof luorocarbons, which
deplete the ozone layer, may be found in old cleaning products. Today other chemicals,
such as isobutene, a petroleum product may be used. Hydrocarbon propellents like
isobutene contribute to smog problems because of their contribution to tropospheric
(ground level) ozone formation.

Alkalies (bases) - Solutions with a pH range between 7.1 to 14.0. An alkali is corrosive
when pH is higher than 11.5. See also pH.
Uses: Many cleaning products (e.g., bleach, detergents, dishwashing soaps, drain openers
and oven cleaners) are alkalies.

Ambient air pollutants: Pollutants for which ambient air quality standards have been
developed. These pollutants include nitrogen dioxide, sulfur dioxide, ozone precursors,
particulate matter, carbon monoxide, and lead.

Bioaccumulate: The process where chemicals are collected and stored in plant and animal
tissue. Some products may contain ingredients that will be taken up by smaller aquatic
plants and animals and increase in concentration through the food chain as these plants
and animals are consumed by larger animals.

Biobased product: Commercial or industrial products (other than food or feed) that
utilize biological products or renewable, domestic, agricultural (plant, animal and marine),
or forestry materials.
27

-------
Biodegradable: The ability of a substance, material or product ingredient to readily
decompose under natural conditions by the action of microbes.

Carcinogen - Chemical capable of causing cancer.

CAS number - Chemical Abstract System number. A unique number used to identify each
chemical.

Chronic health effects - Effects which generally occur as a result of long-term exposure,
and are long duration. Examples include cancer, liver damage and chronic bronchitis.

Chronic toxicity: A chemical that is toxic over continual/repeated exposure.

-------
Corrosive - Chemical which, upon contact can cause deep tissue damage, such as burns to
eyes or skin.

Flashpoint - Lowest temperature for sufficient vapor to form in the presence of oxygen to
permit ignition.

Hazardous ingredient - Toxic, corrosive, ignitable, or reactive ingredient.

Incompatible - Chemicals which are incompatible react violently or produce toxic
byproducts.

Irritation - Redness, swelling or tissue damage caused by chemicals. The degree of
irritation is dependent on dose. Chemical irritation may result in mild skin itching, or fatal
damage to the lungs.

LD50/Lethal dose - A measure of acute toxicity. The lethal dose that will kill 50% of lab
animals exposed to it orally or through the skin. The lower the LD50, the more toxic the
compound.

Mutagen - A chemical that can alter genetic material in humans.
29

-------
Organic chemical - A chemical which contains carbon. Chemicals which do not contain
carbon are termed "inorganic".

Oxidizer (oxidizing agent) - A chemical capable of reacting with other chemicals in an
"oxidation" reaction. Chemical reactions involving strong oxidizers may release heat or be
explosive.

Ozone depletion - Destruction of the stratospheric ozone layer which shields the earth
from ultraviolet radiation harmful to life. This destruction of ozone is caused by the
breakdown of certain chlorine and/or bromine containing compounds (chlorof luorocarbons
or halons), which break down when they reach the stratosphere and then catalytically
destroy ozone molecules.

pH - A measure of the acidity or alkalinity of a solution. A pH of 7 is considered neutral.
A pH greater than 7 indicates alkalinity. A pH less than 7 indicates acidity. In the
absence of specific test data on irritation, pH provides some insight into whether a
product will be corrosive or cause irritation. Products with very high or very low pH (11.5
or 2) should be assumed to be corrosive. High or low pH values (e.g., between 9 and 11, or
between 4 and 2) indicate the product would be more irritating than neutral pH products
where the pH is closer to 7.

Sensitizer - A chemical that causes a substantial proportion of exposed people or animals
to develop an allergic reaction after repeated exposure to the chemical.

Teratogen - A chemical that causes malformation in the fetus and/or birth defects in
humans.

Volatile Organic Compounds (VOCs) - In this context, VOC means any organic compound
(carbon containing) which has a vapor pressure of greater than 0.1 mm Hg or, if the vapor
pressure is unknown, has 12 or fewer carbon atoms. VOCs in cleaning products are of
potential concern because of indoor air exposures to office workers and others. They are
also of concern because they contribute to the formation of smog in outdoor air. Some
30

-------
chemicals considered VOCs include acetone, benzene, perchloroethylene, among many
others.

Explanation of Sample Material Safety Data Sheets

-------
INTRODUCTION TO MATERIAL SAFETY DATA SHEETS (MSDS)

An understanding on how to interpret an MSDS is your best defense against accidents and
injury. On the following pages are descriptions of the sections contained in an MSDS, and
short notes that will help you find and interpret the information the Occupational Safety
and Health Administration (OSHA) requires on a typical good-quality sheet.

There is no single mandatory format for the MSDS. Therefore each MSDS may look a
little different, but all will provide, at a minimum, the required information as mandated by
OSHA's Hazard Communication Standard. Variety will occur in the section titles, and
contents of sections. Some manufacturers may be more explicit with their information
than others.

I. CHEMICAL IDENTIFICATION

This section, (also denoted as Product Information, or Material Identification) identifies
the chemical or trade name product on the label, and its supplier. The manufacturers
name, address, telephone number, and emergency telephone number will be located here.
This section may also contain descriptive terms to further help identify the material, such
as chemical family, molecular weight, and chemical formula. The material identity, including
its chemical, common names and synonyms will be found in this section. For example, brand
name or trade name: Clorox; chemical name: sodium hypochlorite; common name: bleach.

II. COMPONENTS OR INGREDIENTS

Chemical names and percentages of the chemicals that comprise the product will be
identified in this section. Some manufacturers may only list those components that
present a physical or health hazard and are present at or above 1% in the mixture. If a
component is identified as a carcinogen by the National Toxicology Program (NTP), the
International Agency for Research on Cancer (IARC), or by OSHA, it will generally be
noted here, or footnoted in this section, when present at or above 0.1% in the product.
Some manufacturers use a separate section for noting carcinogenicity, or may include
this status in the "Health Hazard" section.

The only time you won't find the identity of a chemical component listed here is when the
company has claimed it as a trade secret. The MSDS will still describe hazards and safety
precautions of the trade secret chemicals.

-------
III. PHYSICAL AND CHEMICAL DATA

This section describes the product appearance, odor, and other physical and chemical
characteristics. Some of the following items may be applicable to the material:

Boiling Point (BP):
The boiling point is the temperature at which a liquid turns into a vapor. Flammable
materials with low BPs generally present fire hazards. In the case of a chemical
mixture, the manufacturer may either list the BP value as a range of temperatures
or that of the component with the lowest value.
Melting Point:
The melting point is the temperature at which a solid changes to a liquid.

Boiling Point and Melting Points are helpful in preventing dangerous changes in
state, such as from a liquid to a breathable gas.

Vapor Pressure:
Vapor pressures are useful in learning how quickly a material becomes airborne
within the workplace and thus how quickly a worker is exposed to it. Vapor
pressures reported on MSDS are in millimeters of mercury (mm Hg) at 68° F(20°
C), unless otherwise stated. In the case of a chemical mixture, the manufacturer
may list the value as a range or that of the component with the highest value.

For example; values less than 1.0 mm Hg at 20°C would be considered "non-volatile"
and above 100 would be considered "highly volatile."

Vapor Density:
The vapor density is compared to air which equals 1. Materials lighter than air have
vapor densities less than one. Materials heavier than air have vapor densities
greater than one. All vapors and gases mix with air, but the lighter materials tend
to rise and dissipate (unless confined). Heavier vapors and gases are likely to
concentrate in low or enclosed places, and may create toxic, fire or explosion
hazards.
Evaporation Rate:
The evaporation rate is the rate at which a material vaporizes from the liquid or
solid state when compared to a known material's vaporization rate. This rate is
useful in evaluating a material's health and fire hazards.

-------
Specific Gravity:
The specific gravity is an expression of the density (or heaviness) of a material as
compared to water = 1. Insoluble materials with specific gravity of greater than one
will sink in water. Insoluble materials with a specific gravity less than one will float
on water, which is an important consideration for fire suppression and spill cleanup.
Water Solubility:
Water solubility expresses the percentage of a material that will dissolve in water.
Water solubility is useful in determining cleanup methods for spills and fire-
extinguishing methods for a material.
pH:
The pH value represents a scale from 0-14 that describes the acidity or alkalinity
of a material. Water has a pH of 7. pH is an important consideration when
determining corrosive properties. Materials on the low end of the scale will be more
acidic, materials on the high end of the scale will be more alkaline or caustic.

• pH 1-5 - strongly acidic (For comparison Coke & Pepsi have a pH of around
3.4)
• pH 5-7 - weakly acidic
• pH 7-9 - weakly basic/caustic
• pH 9-14 - strongly basic /caustic

Appearance and Odor:
Appearance and odor refer to the general characteristics of the material, e.g.
powder, colorless liquid, aromatic odor. The visual appearance of a product is also
useful as an aid in verifying the product and that it is correctly labeled.

IV. PHYSICAL HAZARDS

This section gives potential f lammability and explosion hazards, recommended procedures
in handling these hazards, and storage considerations. This section also contains reactivity
data. Many manufacturers divide the physical hazards category into two sections, the
"Fire and Explosion Data" and "Reactivity Data."

A. FIRE ANO EXPLOSION OATA
Flash Point:
The flash point is defined by the National Fire Protection Association (NFPA) as
the lowest temperature at which a flammable liquid gives off sufficient vapor to
form an ignitable mixture with air near its surface or within a vessel. Special
precautions should be taken when the product has a low flash point. Materials

-------
having a low flash point are a greater fire hazard than materials having a high flash
point.
Flammable Limits (Explosive Limits):
Flammable limits refer to the range of flammable gas or vapor concentrations
between which ignition will occur if an ignition source is present. LFL (or LEL) is the
lower flammable limit. UFL (or UEL) is to the upper flammable limit. All
concentrations between LFL and UFL are in the flammable range, and special
precautions are needed to prevent ignition or explosion.
Ignition Temperature:
The ignition temperature is the lowest temperature at which a combustible material
ignites in air and continues to burn independently of the source of heat.
Autoignition Temperature:
Autoignition temperature describes the minimum temperature to which a substance
must be heated, without the application of a flame or spark, which will cause that
substance to ignite.
Hazardous Decomposition Products:
This area will describe the known or expected hazardous products resulting from
heating, burning, or other reactions.
Extinguishing Media:
Extinguishing media specifies the firefighting agents that should be used to
extinguish fires. Some chemicals react violently in the presence of water, so other
methods, such as the use of foam or COz (carbon dioxide) should be followed.
Firefighting Equipment:
This will describe equipment used to protect firefighters from toxic products of
vaporization, combustion, or decomposition in fire situations.
Firef ighting Methods:
If unusual fire hazards are involved or special f iref ighting procedures mandated,
this will be specified here.
NFPA Codes:
Fire Diamond - National Fire Protection Association -NFPA Hazard Rating.
Per "NFPA 704" publication. A visual system, as illustrated on the following pages,
that provides a general idea of the inherent hazards, and their severity, of
materials relating to fire prevention, exposure, and control. The NFPA fire diamond

-------
B. REACTIVITY OATA:

This area will describe chemical incompatibilities, and whether or not the substance is
stable. This section is important in determining which situations and substances to keep
the product away from to avoid unfavorable conditions.

Chemical Incompatibilities:
This section will list the chemicals that might cause the product to burn, explode,
release dangerous byproducts or otherwise "react" unfavorably, when they come in
contact with the product.
Chemical Instabilities:
This section will describe environmental conditions to avoid, such as heat or direct
sunlight, to prevent hazardous reactions.
Hazardous Polymerization:
This area will tell you if the material will polymerize, or react with itself. Hazardous
polymerization is a reaction which takes place at a rate which produces rapid build-
up of large amounts of energy (heat and pressure) that can lead to explosion. This
section indicates whether hazardous polymerization may or may not occur, and
under what storage conditions.
V. HEALTH HAZARDS

Manufacturers provide data on health hazards under a variety of section titles, including
health effects, and first aid procedures. At a minimum this information should contain
information regarding signs and symptoms of overexposure, primary routes of entry, first
aid and emergency procedures, as well as medical conditions aggravated by overexposure.

Exposure Recommendations:
Exposure recommendations may be listed here or under the "Components or
Ingredients" section. These recommendations are descriptors establishing the
concentration of the chemical to which you can be safely exposed. They are often
listed as permissible exposure limit (PEL) or threshold limit value (TLV).
PEL:
Permissible exposure limit is a term established by OSHA that may be expressed
as a Time Weighted Average (TWA) or as a ceiling exposure limit. The PEL
indicates the permissible concentration of air contaminants to which nearly all
8

-------
      workers may be repeatedly exposed eight hours a day, forty hours a week, over a
      working lifetime (30 years) without adverse health effects.
TLV:
      Threshold Limit Value is a term used by ACGIH to express airborne concentration
      of a material to which almost all workers can be exposed without adverse effects.
      ACGIH expressed TLVs in three ways:
      TLV-TWA: The allowable Time-weighted Average concentration for a normal 8-
      hour workday or 40-hour work week.
      TLV-STEL: The Short-Term Exposure Limit, or maximum concentration for a
      continuous 15-minute exposure period (maximum of four such periods per day, with
      at least 60 minutes between exposure periods, and provided the daily TLV-TWA is
      not exceeded).
      TLV-C: The ceiling exposure limit-the concentration that should not be exceeded
      even instantaneously.
Emergency and First Aid Procedures:
      This section will describe how to administer first aid and emergency procedures in
      case of eye and skin contact, ingestion, and inhalation.
Primary Routes of Entry:
      The MSDS will explain the most likely route of exposure and entry into your body
      based on properties and expected usages of the chemical or trade name product.
      This may include, inhaling, swallowing, or absorption through your skin.
Acute and chronic health effects:
      These sections will explain what signs and symptoms to watch out for, e.g.
      headache, dizziness, nausea, or rashes.
      Acute health effects or acute exposure is an adverse effect due to a single or
      short term overexposure, with symptoms developing rapidly. It refers to the most
      common effects that would be expected to occur from direct contact (eye, skin,
      inhalation, or ingestion) of the product.
      OSHA's definition of highly toxic and toxic are included on the following page:

-------
A highly toxic substance is one having:
1. An oral LD>5o of 50 mg/kg or less.
2. A dermal LD>5o of 200 mg/kg or less.
3. An inhalation LCso of 200 ppm or less of gas or vapor; or 2 mg/l or less of mist,
fume or dust.
A toxic substance is one having:
1. An oral LDso between 50 and 500 mg/kg.
2. A dermal LD50 between 200 and 1000 mg/kg.
3. An inhalation LC$o between 200 ppm, 2000 ppm of gas or vapors, or between 2
and 20 mg/l of mist fume or dust.
Chronic health effects or chronic exposure refer to the adverse effects that are
most likely to occur from repeated, prolonged or long term exposure. It describes
symptoms that develop over a long period of time, or that recur frequently.
LC5o Lethal Concentration 50, or median lethal concentration:
The concentration of a material in air that on the basis of laboratory tests
(respiratory route) is expected to kill 50% of a group of test animals when
administered as a single exposure in a specific time period, usually one hour. The
LCso is expressed as parts of material per million parts of air, by volume (ppm) for
gases and vapors, as micrograms of material per liter of air (ug/l), or milligrams of
material per cubic meter of air (mg/m3) for dusts and mists, as well as for gases
and vapors.
LCi0 Lethal Concentration Low:
The lowest concentration of a substance in air reported to have caused death in
humans or animals. The reported concentrations may be entered for periods of
exposure that are less than 24 hours (acute) or greater than 24 hours (subacute
and chronic).
L&50 Lethal Dose 50:
The single dose of a substance that causes the death of 50% of an animal
population from exposure to the substance by any route other than inhalation.
Other lethal-dose percentages, such as LDi, LDio, LDso, and LDgg may be in the
scientific literature. LDso is usually expressed as milligrams or grams of material
per kilogram of animal weight (mg/kg or g/kg).
LDi_o Lethal Dose Low:
The lowest dose of a substance introduced by any route, other than inhalation,
reported to have caused death in humans or animals.

HMIS Codes:

The Hazardous Materials Identification System, HMIS, was developed by the National
Paint <& Coatings Association (NPCA) to help employers comply with OSHA's Hazard
Communication (HCS), 29 CFR 1910.1200

The system utilizes colored bars, numbers and symbols to convey the hazards of chemicals
used in the workplace.

Do not confuse HMIS® labels (colored bars) with NFPA  labels (colored diamonds). The two
systems are similar but not identical.
       Health (BLUE)
       The Health section conveys the health hazards of the material. In the
       latest version of HMIS®, the blue Health bar has two spaces, one for an
       asterisk and one for a numeric hazard rating.

       If present, the asterisk signifies a chronic health hazard, meaning that
       long-term exposure to the material could cause a health problem such as
       emphysema or kidney damage. NFPA lacks this important information
       because the NFPA system is meant only for emergency or acute (short-
       term) exposures.

       According to NPCA, the numeric hazard assessment procedure is different
       than that used by NFPA. However, there was no publicly available
       information explaining the differences. On a qualitative level, the
       numbering  systems are more or less  identical, with a 0 to 4 scale where 0
       indicates minimal hazard and 4 indicates an extreme hazard.
                                                                                11

-------
Flammability (RED)
According to the NPCA, the criteria used to assign numeric values (0=low
hazard to 4=high hazard) are identical to those used by NFPA. In other
words, in this category, the systems are identical.
Reactivity (YELLOW)
According to the NPCA, the criteria used to assign numeric values (0=low
hazard to 4=high hazard) are identical to those used by NFPA. In other
words, in this category, the systems are identical.
Personal Protection (WHITE)
This is by far the largest area of difference between the NFPA and HMIS®
systems. In the NFPA system, the white area is used to convey special
hazards whereas HMIS® uses the white section to indicate what personal
protective equipment (PPE) should be used when working with the material.
VI. SPILL OR LEAK PROCEDURES

This section will describe precautions and actions to be taken in the event of a spill or leak
and methods of clean-up and disposal.

VII. PROCEDURES AND PRECAUTIONS FOR SAFE HANDLING, STORAGE
AND USE:

This section may alternatively be titled Special Protection, Personal Protective Equipment,
or Safe Handling and Storage Requirements. This area of the MSDS contains control
measures such as personal protective equipment recommendations, engineering controls
and work practices that are necessary for the safe handling and use of the product. If
protective equipment is needed, this section will list the specific types that are
recommended, such as respirators, gloves, and goggles. Specific steps and precautions to
take to safeguard your health, such as proper ventilation requirements, also are described
here. Ventilation is described using two terms; local or general. Local ventilation refers an
exhaust duct system with a hood or enclosure. General ventilation refers to a dilution fan
in the wall or ceiling. Storage and handling requirements addressed in this section may
12

-------
include such things as grounding containers during a transfer of f lammables to prevent
static electricity as an ignition source.

VIII.  SPECIAL PRECAUTIONS OR OTHER COMMENTS:

The manufacturer may describe special precautions if there is something other than
standard information the user should  be aware of. Regulatory compliance issues such as
Department of Transportation (DOT)  policies for handling and transportation, or Resource
Conservation and Recovery Act (RCRA) classification for proper disposal may also be
addressed here.

|V FIRST AID MEASURES

SYMPTOMS OF OVEREXPOSURE AND FIRST AID TREATMENT
Eye contact: Reddening may develop. Immediately rinse the eye with large quantities of cool water; continue 10-15
minutes or until the material has been removed; be sure to remove contact lenses, if present, and to lift
upper and lower lids during rinsing. Get medical attention if irritation persists.

Skin contact: Minimal effects, if any; rinse skin with water, rinse shoes and launder clothing before reuse. Reversible
reddening may occur in some dermal-sensitive users; thoroughly rinse area and get medical attention if
reaction persists.

Swallowing: Essentially non-toxic. Give several glasses of water to dilute; do not induce vomiting. If stomach upset
occurs, consult physician.

Inhalation: Non-toxic. Exposures to concentrate-mist may cause mild irritation of nasal passages or throat; remove to
fresh air. Get medical attention if irritation persists,

V. FIRE FIGHTING MEASURES

Flammafciiity Here's an example of an alternative labeling system
          designed by the National Fire Protection Association
          (NFPA) that uses color, numbers and other information to
          convey the hazards of the chemical.
    s

  MRflOMIW
The NFPA system uses a diamond-shaped diagram of symbols and numbers to
indicate the degree of hazard associated with a particular chemical or material.
These diamond shaped symbols are placed on containers of chemicals or materials to
identify the degree of hazard associated with the chemical or material. The diagram
identifies four color-coded categories of hazard for each material. Each category is
divided  in levels of hazard potential with increasing numbers indicating increasing
hazards. The  exception is the white section that provides Special Hazards
information. The abbreviated degrees of hazard in  each of these categories are given
as follows:
The degree of health hazard of a chemical or material is based on the form or
condition of the material, as well as its inherent properties. The degree of health
hazard of a material should indicate the degree of personal protective equipment
required for working safety with the material.

    •   1 is for slightly hazardous (toxic) material which requires only minimal
       protection (for example, safety glasses and gloves) in addition to normal
       work clothing to work with safely.
    •   2 is for moderately toxic or a hazardous or moderately toxic material which
       requires additional PPE or equipment (e.g. chemical goggles, lab/work
       smock, local ventilation) in addition to that required for less toxic material.
       Consult the MSDS for specific health hazard and proper PPE to use with this
       material.
    •   3 or 4 is for highly to extremely toxic (deadly) materials (and any
       carcinogen, mutagen, or teratogen). These materials will require specialized
       equipment (e.g. respirator or exhaust hood, full  face shield, rubber apron,
       specialized glove, handling tongs,  etc) beyond that required for moderately
       toxic material.  You must consult the MSDS and/or  other safety information to
       determine the  hazard (acute or chronic) and the proper PPE and engineering
       controls to safely use this material.
    imability or Fire Hazard
The flammability or fire hazards deal with the degree of susceptibility of the material
to ignite and burn. The form or condition of the materials, as well as their properties,
affects the extent of the hazard. Many hazardous materials such as acetone and
gasoline, have a flash point (ignition temperature) far below freezing and will readily
ignite with a spark if the vapor concentration is sufficient.

-------
   •   1 is for materials with a flash point above 200°F.
   •   2 is for materials with a flash point below 200°F but above 100°F.
   •   3 is for materials with a flash point below 100°F but above 73°F.
   •   4 is for materials with a flash point below 73°F.
The reactivity hazards deal with the potential of a material or chemical to release
energy. Some materials are capable of rapid energy release without any catalyst,
while others can undergo violent eruptive or explosive reactions if they come in
contact with water or other materials. Generally this rating is used to indicate the
potential to react if the material is heated, jarred, or shocked.

   •   1 indicates a material that may be reactive if heated and one that reacts with
       water.
   •   2 indicates a material that may react violently without detonation.
   •   3 indicates a material that may detonate or explode if subjected to a strong
       initiating force or heating under confinement.
   •   4 indicates a material that readily detonates or explodes.
Special Hazard
An open space at the bottom of the NFPA diagram can be used to indicate additional
information about the chemical or material. This information may include the
chemical or material's radioactivity, proper fire extinguishing agent, skin hazard, its
use in pressurized containers, protective equipment required, or unusual reactivity
with water.
   •   OX or OXY indicates a material that is an oxidizer.
   •   W indicates a material that is water reactive.
   •   ALK indicates a material that is alkali.
   •   COR indicates a material that is corrosive.
   •   RAD indicates a material that is radioactive.

Below are two other examples of an alternative labeling system designed by the
National Paint & Coatings Association (NPCA). The labeling scheme is called the
Hazardous Material Identification System (HMIS). It uses a similar system to convey
the hazards of the chemical.

                       HMIS I & II
                             HMIS III

-------
HMIS® labels can appear in a variety of formats. Some will include additional spaces
to list target organ effects, a labeling requirement under the HCS, and other
information, but the four colored areas shown here will always be present.

The new HMIS III label provides employees the tools to understand and handle
chemicals exhibiting a variety of physical hazards with a  far greater degree of
precision.  Although "Reactivity" has provided useful information for physical hazards,
HMIS® III now provides more information about a  chemical's physical hazard(s).
The new HMIS III not only specifically incorporates each  hazard, with specific criteria
to evaluate the degree of hazard, but permits employers to identify the hazard
present with an icon or symbol. Under the new HMIS® III, a worker can know
immediately, for example, that a material he is  handling  is rated as an explosive,
and that it is rated as a "3" giving him or her much more precise and useful
information about the safe handling of that material.

Specific sections of an HMIS® label include the  following:
 • The Health section conveys the health hazards of the material. In the latest
 version of HMIS®, the blue Health bar has two spaces, one for an asterisk and one
 for a  numeric hazard rating.

 If present, the asterisk (*) signifies a chronic health hazard, meaning that long-
 term  exposure to the material could cause a health problem such as emphysema or
 kidney damage.  NFPA lacks this important information because the NFPA system is
 meant only for emergency or acute (short-term) exposures.

 The numbering systems are more or less identical to NFPA, with a 0 to 4 scale
 where 0 indicates minimal hazard and 4 indicates an extreme hazard.
      iiKimnPi
 • For HMIS I and II, the criteria used to assign numeric values (0 = low hazard to 4
 = high hazard) are identical to those used by NFPA. In other words, in this
 category, the systems are identical.

 • For HMIS III, the flammability criteria are defined according to OSHA standards. A
 0 to 4 scale is still used.
 Reactivity
 • The criteria used to assign numeric values (0 = low hazard to 4 = high hazard)
 were identical to those used by NFPA. In other words, in this category, the systems
 are identical.
 Personal Protection
 • HMIS® uses the white section to indicate what PPE should be used when working
 with the material.
 HMIS® uses a letter coding system or variant for this section. Below is the lettering
 scheme along with a series of graphics meant to reinforce the meaning of each
 letter:

The Douglass County School District has established desirable attributes for the
evaluation of five (5) representative categories of janitorial cleaning products as listed
below. Offerers may propose more than one product within a product category (example
only - brand "X" and brand " Y" for all-purpose cleaner) and/or propose a single product
that addresses more than one product category or cleaning task (example only - brand
"X" as all-purpose cleaner and general disinfectant).

       Janitorial Cleaning Product Categories

       (1)    Ail-Purpose Cleaner
       (2)    General Degreaser
       (3)    General Disinfectant
       (4)    Floor Stripper
       (5)    Bathroom Cleaner

II.     Desirable Attributes for Janitorial Cleaning Products

The following ten (10) attributes should be present in some verifiable or demonstrable
degree in an offered product. It is required that offerers shall provide a Material Safety
Data Sheet (MSDS), equivalent information, and/or any additional information
specifically requested for each product offered in the product categories specified in
Section I to enable the District to evaluate the desirable characteristics with respect to that
product.

Failure of a product to meet any of the criteria listed below, or failure to submit
acceptable verification that a product meets these criteria, may lead to the automatic
rejection of the bid.

       (1)    Carcinogen:  The District wishes entirely to eliminate the use of products
             containing known and probable carcinogens.  Accordingly, no chemical
             cleaning product shall contain constituent compounds that are classified as
             known or probable carcinogens by any of the following organizations:

                 •  American Conference of Governmental Industrial Hygienists
                    (ACGIH);
                 •  International Agency for Research on Cancer (IARC);
                 •  National Institute of Occupational Health and Safety  (NIOSH);
                 •  National Toxicology Program (NTP); and,
                 •  Occupational Health and Safety Organization (OSHA).

-------
(2) Flammability/Flash Point: Products that do not ignite easily are favored.

(3) Corrosiveness (pH): Products that have a pH closer to neutral are favored.

(4) Chronic Health Risks: Products that pose no potential for chronic health
risks are favored.

(5) Skin/Eye Irritant: Products that are less irritating to the skin and eyes are
favored.

(6) Volatile Organic Compound (VOC) Content: Products with the lowest
VOC levels possible are favored. Most desirable are products that do not
contain VOC's in concentrations that exceed 10% of the weight of the
product.

(7) Ozone-Depleting Compounds: Products that do not contain ozone-
depleting compounds are favored.

(8) Biodegradability: Products that are partially or completely biodegradable
are favored.

(9) Product Packaging: Products that are packaged in recyclable or reusable
containers (such as use of refillable product distribution devices and/or
concentrates) and containers which are made with a percentage of post-
consumer recycled materials are favored. Additionally, products that use
no, or only a minimal amount of, polypropylene and/or polystyrene
("Styrofoam") packaging are favored.

(10) Energy Needs: Products that work effectively in cold water, which
decreases the amount of energy consumption necessary, are favored.

Some wording for potential additional attributes depending on District priorities:

(A) No Sealed Aerosol Spray Cans: All chemical cleaning products must be
available in either a liquid form or manual pump action sprays and/or
concentrates that can be dispensed into pump bottles for use.

(B) Dyes and Fragrances: Products that do not contain dyes or fragrances
are favored.

III. Product Efficacy Testing

In addition to being evaluated for environmental preferability, offered products will be
evaluated for their efficacy. That is, a chemical cleaning or recycled content product that
meets the desirable attributes still may be deemed ineffective for its intended purpose(s)
after testing by the evaluators. Such products will be rejected.

-------
IV.    Training Program

The District believes that an effective training program is central to the success of using
environmentally preferable products. Vendors who can supply a quality on-site training
program and be accessible to trouble-shoot problem applications are favored.

              NIOSH  Pocket Guide to Chemical Hazards


                                         INTRODUCTION

  The NIOSH Pocket Guide to Chemical Hazards is intended as a source of general industrial hygiene information for
  workers, employers, and occupational health professionals. The Pocket Guide presents key information and data in
  abbreviated tabular form for 677 chemicals or substance groupings (e.g., manganese compounds, tellurium compounds,
  inorganic tin compounds, etc.) that are found in the work environment. The industrial hygiene information found in the
  Pocket Guide should help users recognize and control occupational chemical hazards. The chemicals or substances
  contained in this revision include all substances  for which the National Institute for Occupational Safety and Health
  (NIOSH) has recommended exposure limits (RELs) and those with permissible exposure limits (PELs) as found in the
  Occupational Safety and Health Administration (OSHA) General Industry Air Contaminants Standard (29 CFR
  1910.1000).

  Background

  In 1974, NIOSH (which is responsible for recommending health and safety standards) joined OSHA (whose
  jurisdictions include promulgation and enforcement activities) in developing a series of occupational health standards
  for substances with existing PELs. This joint effort was labeled the Standards Completion Program and involved the
  cooperative efforts of several contractors and personnel from various divisions within NIOSH and OSHA. The
  Standards Completion Program developed 380 substance-specific draft standards with supporting documentation that
  contained technical information and recommendations needed for the promulgation of new occupational health
  regulations. The Pocket Guide was developed to make the technical information in those draft standards more
  conveniently available to workers, employers, and occupational health professionals. The Pocket Guide is updated
  periodically to reflect new data regarding the toxicity of various substances and any  changes in exposure standards or
  recommendations.

  Data Collection and Application

  The data were collected from a variety of sources, including NIOSH policy documents such as criteria documents and
  Current Intelligence Bulletins (CIBs), and recognized references in the fields of industrial hygiene, occupational
  medicine, toxicology, and analytical chemistry.

                               NIOSH RECOMMENDATIONS

  Acting under the authority of the Occupational Safety and Health Act of 1970 (29 USC Chapter 15) and the Federal
  Mine Safety and Health Act of 1977 (30 USC Chapter 22), NIOSH develops and periodically revises recommended
  exposure limits (RELs) for hazardous substances or conditions in the workplace. NIOSH also recommends appropriate
  preventive measures to reduce or eliminate the adverse health and safety effects of these hazards. To formulate these
  recommendations, NIOSH evaluates all known and available medical, biological, engineering, chemical, trade, and
  other information relevant to the hazard. These recommendations are then published and transmitted to OSHA and the
  Mine Safety and Health Administration (MSHA) for use in promulgating legal standards.

  NIOSH recommendations are published in a variety of documents. Criteria documents recommend workplace exposure

limits and appropriate preventive measures to reduce or eliminate adverse health effects and accidental injuries.

Current Intelligence Bulletins (CIBs) are issued to disseminate new scientific information about occupational hazards.
A CIB may draw attention to a formerly unrecognized hazard, report new data on a known hazard, or present
information on hazard control.

Alerts, Special Hazard Reviews, Occupational Hazard Assessments, and Technical Guidelines support and
complement the other standards development activities of the Institute. Their purpose is to assess the safety and health
problems associated with a given agent or hazard (e.g., the potential for injury or for carcinogenic, mutagenic, or
teratogenic effects) and to recommend appropriate control and surveillance methods. Although these documents are
not intended to supplant the more comprehensive criteria documents, they are prepared to assist OSHA and MSHA in
the formulation of regulations.

In addition to these publications, NIOSH periodically presents testimony before various Congressional committees and
at OSHA and MSHA rulemaking hearings.

A complete list of occupational safety and health issues for which NIOSH has formal policies (e.g., recommendations
for occupational exposure to chemical and physical hazards, engineering controls, work practices, safety
considerations, etc.) can be found in NIOSH Recommendations for Occupational Safety and Health: Compendium of
Policy Documents and Statements [DHHS (NIOSH) Publication No. 92-100].

HOW TO USE THIS POCKET GUIDE

The Pocket Guide has been designed to provide chemical-specific data to supplement general industrial hygiene
knowledge. To maximize the amount of data provided in this limited space, abbreviations and codes have been used
extensively. These abbreviations and codes, which have been designed to permit rapid comprehension by the regular
user, are discussed for each column in the following subsections.

Chemical Name and Structure/Formula, CAS and RTECS Numbers, and DOT ID and Guide
Numbers

Chemical Name and Structure/Formula - The chemical name found in the OSHA General Industry Air
Contaminants Standard (29 CFR 1910.1000) is listed first. The chemical formula is also provided under the chemical
name.

CAS and RTECS Numbers - The Chemical Abstracts Service (CAS) number, in the format xxx-xx-x, is unique for
each chemical and allows efficient searching on computerized databases. The NIOSH Registry of Toxic Effects of
Chemical Substances (RTECS) number, in the format ABxxxxxxx, may be useful for obtaining additional toxicologic
information on a specific substance.

DOT ID and GUIDE Number - The U.S. Department of Transportation (DOT) identification number and the
corresponding guide number. Their format is xxxx xxx. The Identification number (xxxx) indicates that the chemical is
regulated by DOT. The Guide number (xxx) refers to actions to be taken to stabilize an emergency situation; this
information can be found in the 2000 Emergency Response Guidebook (Office of Hazardous Materials Training and
Initiatives [DHM-50], Research and Special Programs Administration, U.S. Department of Transportation,
Washington, D.C. 20590-0001; for sale by the U.S. Government Printing Office, Superintendent of Documents, Mail
Stop: SSOP, Washington, D.C. 20402-9328). A page index for all DOT ID numbers listed is included at the back of
the Pocket Guide to help the user locate a specific substance; please note however, that many DOT numbers are NOT
unique for specific substances.

Synonyms, Trade Names, and Conversion Factors

Common synonyms and trade names are listed alphabetically for each chemical. Factors for the conversion of ppm

Introduction to the Online NIOSH Pocket Guide to Chemical Hazards

(parts of vapor or gas per million parts of contaminated air by volume) to mg/m3 (milligrams of vapor or gas per cubic
meter of contaminated air) at 25 °C and 1 atmosphere are listed for chemicals with exposure limits expressed in ppm.

Exposure Limits

The NIOSH recommended exposure limits (RELs) are listed first in this column. Unless noted otherwise, RELs are
time-weighted average (TWA) concentrations for up to a 10-hour workday during a 40-hour workweek. A short-term
exposure limit (STEL) is designated by "ST" preceding the value; unless noted otherwise, the STEL is a 15-minute
TWA exposure that should not be exceeded at any time during a workday. A ceiling REL is designated by "C"
preceding the value; unless noted otherwise, the ceiling value should not be exceeded at any time. Any substance that
NIOSH considers to be a potential occupational carcinogen is designated by the notation "Ca" see (Appendix A. which
contains a brief discussion of potential occupational carcinogens).

The OSHA permissible exposure limits (PELs), as found in Tables Z-l, Z-2, and Z-3 of the OSHA General Industry
%
Air Contaminants Standard (29 CFR 1910.1000), that were effective on July 1, 1993 and which are currently enforced
jj
by OSHA are listed next. [ Note: In July 1992, the llth Circuit Court of Appeals in its decision in AFL-CIO v.
OSHA, 965 F.2d 962 (11th Cir., 1992) vacated more protective PELs set by OSHA in 1989 for 212 substances, moving
them back to PELs established in 1971. The appeals court also vacated new PELs for 164 substances that were not
previously regulated. The substances for which OSHA PELs were vacated on June 30, 1993 are indicated by the
symbol "f" following OSHA PEL in this column. A number of RELs are based on NIOSH concurrence with the data
presented and the airborne exposure limits proposed in this rulemaking.] Unless noted otherwise, PELs are TWA
concentrations that must not be exceeded during any 8-hour workshift of a 40-hour workweek. A STEL is designated
by "ST" preceding the value and is measured over a 15-minute period unless noted otherwise. OSHA ceiling
concentrations (designated by "C" preceding the value) must not be exceeded during any part of the workday; if
instantaneous monitoring is not feasible, the ceiling must be assessed as a 15-minute TWA exposure. In addition, there
are a number of substances from Table Z-2 (e.g., beryllium, ethylene dibromide, etc.) that have PEL ceiling values that
must not be exceeded except for specified excursions. For example, a "5-minute maximum peak in any 2 hours"
means that a 5-minute exposure above the ceiling value, but never above the maximum peak, is allowed in any 2 hours
during an 8-hour workday. Appendix B contains a brief discussion of substances regulated as carcinogens by OSHA.

Concentrations are given in ppm, mg/m3, mppcf (millions of particles per cubic foot of air as determined from
counting an impinger sample), or fibers/cm3 (fibers per cubic centimeter). The "[skin]" designation indicates the
potential for dermal absorption; skin exposure should be prevented as necessary through the use of good work practices
and gloves, coveralls, goggles, and other appropriate equipment. The "(total)" designation indicates that the REL or
PEL listed is for "total particulate" versus the "(resp)" designation which refers to the "respirable fraction" of the
airborne particulate. Appendix C contains more detailed discussions of the specific exposure limits for certain low-
molecular-weight aldehydes, asbestos, various dyes (benzidine-, o-tolidine-, and o-dianisidine-based), carbon black,

the Pocket Guide with no established RELs at this time and Appendix F contains miscellaneous notes regarding the
OSHA PELs. Appendix G lists the OSHA PELs that were vacated on June 30, 1993.]

IDLH

For the June 1994 Edition of the Pocket Guide, immediately dangerous to life or health concentrations (IDLHs) were
reviewed and, in many cases, were revised and made more protective. As a consequence of the IDLH changes, many
of the respirator recommendations for these substances were also revised. The criteria utilized to determine the
adequacy of existing IDLH values were a combination of those used during the Standards Completion Program and a
newer methodology developed by NIOSH. These "interim" criteria form a tiered approach with acute human toxicity
data being used preferentially, followed next by acute animal inhalation toxicity data, and then finally by acute animal
oral toxicity data to determine an updated IDLH value. When relevant acute toxicity data were insufficient or

  unavailable, the use of chronic toxicity data or an analogy to a chemically similar substance was considered. The
  criteria and information sources for both the original and revised IDLH values are given in Documentation for
  Immediately Dangerous to Life and Health Concentrations (IDLHs) (NTIS Publication No. PB-94-195047). NIOSH is
  currently assessing the various uses of IDLHs and whether the original criteria used to derive the IDLH values are
  valid or if other information or criteria should be utilized. Based on this assessment, NIOSH will develop a  new
  strategy for revising the IDLH values currently listed, as well as for developing new IDLH values for the more than
  300 substances listed in the Pocket Guide without IDLHs.

  The definition of IDLH that was derived during the Standards Completion Program was based on the Mine  Safety and
  Health Administration (MSHA) definition stipulated in 30 CFR 11.3(t). The purpose for establishing an IDLH value in
  the Standards Completion Program was to ensure that a worker could escape without injury or irreversible health
  effects from an  IDLH exposure in the event  of the failure of respiratory protection equipment. The IDLH was
  considered a maximum concentration above which only a highly reliable breathing apparatus providing maximum
  worker protection was permitted. In determining IDLH values, the ability of a worker to escape without loss of life or
  irreversible health effects was considered along with severe eye or respiratory irritation and other deleterious effects
  (e.g., disorientation or incoordination) that could prevent escape. As a safety margin, the Standards Completion
  Program IDLH  values were based on the effects that might occur as a consequence of a 30-minute exposure. However,
  the 30-minute period was NOT meant to imply that workers should stay in the work environment any longer than
  necessary, in  fact, EVERY EFFORT SHOULD BE MADE TO EXIT IMMEDIATELY!

  The current NIOSH definition for an IDLH exposure condition, as stipulated in the NIOSH Respirator Decision Logic
  (DHHS [NIOSH] Publication No. 87-108, NTIS Publication No. PB-91-151183), is a condition "that poses  a threat of
  exposure to airborne contaminants when that exposure is likely to cause death or immediate or delayed permanent
  adverse health effects or prevent escape from such an environment."  The purpose of establishing an IDLH exposure
  concentration is to "ensure that the worker can escape from  a given contaminated environment in the event  of failure
  of the respiratory protection equipment." The NIOSH Respirator Decision Logic  uses these IDLH values as  one of
  several respirator selection criteria. Under the NIOSH Respirator Decision Logic, the most protective respirators (e.g.,
  a self-contained breathing apparatus equipped with a full facepiece and operated in a pressure-demand or other
  positive-pressure mode) would be selected for firefighting, exposure to carcinogens, entry into oxygen-deficient
  atmospheres,  in emergency situations, during entry into an atmosphere that contains a substance at a concentration
  greater than 2,000 times the NIOSH REL or OSHA PEL, and for entry into IDLH atmospheres.

  IDLH values  are listed for over 380 substances. The notation "Ca"  appears in this column for all  substances  that
  NIOSH considers to be potential occupational carcinogens. However, IDLH values that were originally determined in
  the Standards Completion Program  or were recently revised are shown in brackets following the "Ca" designations.
  "10%LEL" indicates that the IDLH was based on 10% of the lower explosive limit for safety considerations even
  though the relevant toxicological data indicated that irreversible health effects or impairment of escape  existed only at
  higher concentrations. "N.D."  indicates that an IDLH has not as yet been determined.

  Physical Description

  This entry provides a brief description of the appearance and odor of each substance.  Notations are made as to whether
  a substance can be shipped as a liquefied compressed gas or whether it has major use as a pesticide.

  Chemical and Physical Properties

  The following abbreviations are used for the chemical  and physical properties given for each substance. "NA"
  indicates that a property is  not applicable, and a question mark (?) indicates that it is unknown.

RGasD Relative density of gases referenced to air = 1 (indicates how many times a gas is heavier than air at the same
temperature)

When possible, the flammability/combustibility of a substance was determined and listed after the specific gravity. The
following OSHA criteria (29 CFR 1910.106) were used to classify flammable or combustible liquids:
Class IA flammable liquid
Class IB flammable liquid
Class 1C flammable liquid
Class II combustible liquid
Class IIIA combustible liquid
Class IIIB combustible liquid
Fl.P. below 73 °F and BP below 100 °F.
Fl.P. below 73 °F and BP at or above 100 °F.
Fl.P. at or above 73 °F and below 100 °F.
Fl.P. at or above 100 °F and below 140 °F.
Fl.P. at or above 140 °F and below 200 °F.
Fl.P. at or above 200 °F.
Incompatibilities and Reactivities

This entry lists important hazardous incompatibilities or reactivities of each substance.

Measurement Methods

This entry provides a source (NIOSH or OSHA) and the method number for which a measurement method can be used
to determine the exposure. Unless otherwise noted, the NIOSH methods are from the 4th edition of the NIOSH Manual
of Analytical Methods (DHHS [NIOSH] Publication No. 94-113). If a different edition of the NIOSH Manual of
Analytical Methods is cited, the appropriate edition and, where applicable, the volume number would be noted [e.g., II-
4 (2nd edition, volume 4)]. The OSHA methods are from the OSHA web site, http://www.osha-
slc.gov/dts/sltc/methods/. "None available" means that no method is available from the NIOSH or OSHA source.

Personal Protection and Sanitation

This column presents a summary of recommended practices for each toxic substance. These recommendations
supplement general work practices (e.g., no eating, drinking, or smoking where chemicals are used). Table 3 explains
the codes used. Each category is described as follows:

SKIN: Recommends the need for personal protective clothing.
EYES: Recommends the need for eye protection.
WASH Recommends when workers should wash the spilled chemical from the body in addition to normal
SKIN: washing (e.g., before eating).
REMOVE: Advises workers when to remove clothing that has accidentally become wet or significantly
contaminated.

Introduction to the Online NIOSH Pocket Guide to Chemical Hazards

CHANGE: Recommends whether the routine changing of clothing is needed.
PROVIDE: Recommends the need for eyewash fountains and/or quick drench facilities.

First Aid

This entry lists emergency procedures for eye and skin contact, inhalation, and ingestion of the toxic substance.

Respirator Recommendations

This entry provides a condensed table of allowable respirator use for those substances for which IDLH values have
been determined. NIOSH is currently reevaluating the IDLH values, and as new or revised IDLH values are developed,
respirator selection recommendations will be incorporated into subsequent editions of the Pocket Guide. In the interim
no respirator recommendations will be made for substances without IDLH values (these will be noted by "To be added
later").

NIOSH has developed a new set of regulations in 42 CFR 84 (also referred to as "Part 84") for testing and certifying
nonpowered, air-purifying, particulate-filter respirators. The new Part 84 respirators have passed a more demanding
certification test than the old respirators (e.g.; dust; dust and mist; dust, mist, and fume; spray paint; pesticide; etc.)
certified under 30 CFR 11 (also referred to as "Part 11"). Under Part 84, NIOSH is allowing manufacturers to continue
selling and shipping Part 11 particulate filters as NIOSH-certified until July 10, 1998. It is important to see the NIOSH
Guide to the Selection and Use of Particulate Respirators (DHHS [NIOSH] Publication No. 96-101) for substitution of
Part 84 respirators for Part 11 respirators.

The first line in the entry indicates whether the "NIOSH" or the "OSHA" exposure limit is used on which to base the
respirator recommendations. The more protective limit between the NIOSH REL or the OSHA PEL is always used.
"NIOSH/OSHA" indicates that the limits are equivalent.

Each subsequent line lists a maximum use concentration (MUC) followed by the classes of respirators, with their
assigned protection factors (APFs), that are acceptable for use up to the MUC. Individual respirator classes are
separated by diagonal lines (/). More protective respirators may be worn. Emergency or planned entry into unknown
concentrations or entry into IDLH conditions are followed by the classes of respirators acceptable for these conditions.
"Escape" indicates that the respirators are to be used only for escape purposes. For each MUC or condition this entry
lists only those respirators with the required APF and other use restrictions based on the NIOSH Respirator Decision
Logic.

In certain cases, the recommended respirators are annotated with the following symbols as additonal information:

* Substance reported to cause eye irritation or damage; may require eye protection
£ Substance causes eye irritation or damage; eye protection needed
A If not present as a fume
I Only nonoxidizable sorbents allowed (not charcoal)
t End of service life indicator (ESLI) required

All respirators selected must be approved by NIOSH and MSHA under the provisions of 30 CFR 11 or by NIOSH
under 42 CFR 84. The current listing of NIOSH/MSHA certified respirators can be found in the NIOSH Certified
Equipment List (DHHS [NIOSH] Publication No. 2001-139). A list of Part 84 respirators can be found on the NIOSH
Home Page (http://www.cdc.gov/niosh/) or obtained by calling 1-800-35-NIOSH.

A complete respiratory protection program must be implemented and must fulfill all requirements of 29 CFR
1910.134. A respiratory protection program must include a written standard operating procedure covering regular
training, fit-testing, fit-checking, periodic environmental monitoring, maintenance, medical monitoring, inspection,
cleaning, storage and periodic program evaluation. Selection of a specific respirator within a given class of

  recommended respirators depends on the particular situation; this choice should be made only by a knowledgeable
  person. REMEMBER: Air-purifying respirators will not protect users against oxygen-deficient atmospheres, and they
  are not to be used in IDLH conditions. The only respirators recommended for fire fighting are self-contained breathing
  apparatuses that have full facepieces and are operated in a pressure-demand or other positive-pressure modes.
  Additional information on the selection and use of respirators can be found in the NIOSH Respirator Decision Logic
  and the NIOSH Guide to Industrial Respiratory Protection (DHHS [NIOSH] Publication No. 87-116).

                                           APPENDIX A

            NIOSH POTENTIAL OCCUPATIONAL CARCINOGENS

  New Policy

     For the past 20 plus years, NIOSH has subscribed to a carcinogen policy that was published in 1976 by Edward J.
  Fairchild, II, Associate Director for Cincinnati Operations, which  called for "no detectable exposure levels for proven
  carcinogenic substances" (Annals of the New York Academy of Sciences, 271:200-207, 1976). This was in response to
  a generic OSHA rulemaking on carcinogens. Because of advances in science and in approaches to risk assessment and
  risk management, NIOSH has adopted a more inclusive policy. NIOSH recommended exposure limits (RELs) will be
  based on risk evaluations using human or animal health effects data, and on an assessment of what levels can be
  feasibly achieved by engineering controls and measured by analytical techniques. To the extent feasible, NIOSH will
  project not only a no-effect exposure, but also exposure levels at which there may be residual risks. This policy applies
  to all workplace hazards, including carcinogens, and is responsive to Section 20(a)(3) of the Occupational Safety and
  Health Act of 1970, which charges NIOSH to ". . .describe exposure levels that are safe for various periods of
  employment, including but not limited to the exposure levels at which no employee will suffer impaired health or
  functional capacities or diminished life expectancy as a result of his work experience."

     The effect of this new policy will be the development, whenever possible, of quantitative RELs that are based on
  human and/or animal data, as well as on the consideration of technological feasibility for controlling workplace
  exposures to the REL. Under the old policy, RELs for most carcinogens were non-quantitative values labeled "lowest
  feasible concentration (LFC)."  [Note: There are a few exceptions to LFC RELs for carcinogens (e.g., RELs for
  asbestos, formaldehyde, benzene, and ethylene oxide are quantitative values based primarily on analytical limits of
  detection or technological feasibility). Also, in 1989, NIOSH adopted several quantitative RELs for carcinogens from
  OSHA's permissible exposure limit (PEL)  update.]

     Under the new policy, NIOSH will also recommend the complete range of respirators (as determined by the NIOSH
  Respirator Decision Logic) for carcinogens with quantitative  RELs. In this way, respirators will be consistently
  recommended regardless of whether a substance is a carcinogen or a non-carcinogen.

  Old Policy

     In the past, NIOSH identified numerous substances that should be treated as potential occupational carcinogens
  even though OSHA might not have identified them as such. In determining their carcinogenicity, NIOSH used the
  OSHA classification outlined in 29 CFR 1990.103, which states in part:

       Potential occupational carcinogen means any substance, or combination or mixture of substances, which
       causes an increased incidence of benign and/or malignant neoplasms, or  a substantial decrease in the
       latency period between exposure and onset of neoplasms  in humans or in one or more experimental
       mammalian species as the result of any oral, respiratory or dermal exposure, or any other exposure which

NIOSH/Appendices to Online NIOSH Pocket Guide to Chemical Hazards

       results in the induction of tumors at a site other than the site of administration. This definition also
       includes any substance which is metabolized into one or more potential occupational carcinogens by
       mammals.

     When thresholds for carcinogens that would protect 100% of the population had not been identified, NIOSH
  usually recommended that occupational exposures to carcinogens be limited to the lowest feasible concentration. To
  ensure maximum protection from carcinogens through the use of respiratory protection, NIOSH also recommended that
  only the most reliable and protective respirators be used. These respirators include (1) a self-contained breathing
  apparatus (SCBA) that has a full facepiece and is operated in a positive-pressure mode, or (2) a supplied-air respirator
  that has a full  facepiece  and is operated in a pressure-demand or other positive-pressure mode in combination with an
  auxiliary SCBA operated in a pressure-demand or other positive-pressure mode.

  Recommendations to be Revised

     The RELs and respirator recommendations for carcinogens listed in this edition of the Pocket Guide still reflect the
  old policy. Changes in the RELs and respirator recommendations that reflect the new policy will be included in future
  editions.

                 THIRTEEN OSHA-REGULATED CARCINOGENS

     Without establishing PELs, OSHA promulgated standards in 1974 to regulate the industrial use of 13 chemicals
  identified as potential  occupational carcinogens.

       • 2-acetylaminofluorene
       • 4-aminodiphenyl
       • benzidine
       • bis-chloromethyl ether
       • 3,3'-dichlorobenzidine
       • 4-dimethylaminoazobenzene
       • ethyleneimine
       • methyl chloromethyl ether
       • alpha-naphthylamine
       • beta-naphthylamine
       • 4-nitrobiphenyl
       • N-nitrosodimethylamine
       • beta-propiolactone

     Exposures of workers to these 13 chemicals are to be controlled through the required use of engineering controls,
  work practices, and personal protective equipment, including respirators. See 29 CFR 1910.1003-1910.1016 for
  specific details of these requirements.

     Respirator selections in the Pocket Guide are based on NIOSH policy, which considers the 13 chemicals to be
  potential occupational carcinogens.

                        SUPPLEMENTARY EXPOSURE LIMITS

  Aldehydes (Low-Molecular-Weight)

NIOSH/Appendices to Online NIOSH Pocket Guide to Chemical Hazards


     Exposure to acetaldehyde has produced nasal tumors in rats and laryngeal tumors in hamsters, and exposure to
  malonaldehyde has produced thyroid gland and pancreatic islet cell tumors in rats. NIOSH therefore recommends that
  acetaldehyde and malonaldehyde be considered potential occupational carcinogens in conformance with the OSHA
  carcinogen policy.

     Testing has not been completed to determine the carcinogenicity of acrolein, butyraldehyde (CAS#: 123-72-8),
  crotonaldehyde, glutaraldehyde, glyoxal (CAS#: 107-22-2), paraformaldehyde (CAS#:  30525-89-4), propiolaldehyde
  (CAS#: 624-67-9), propionaldehyde (CAS#: 123-38-6), and n-valeraldehyde, nine related low-molecular-weight-
  aldehydes.

     However, the limited studies to date indicate that these substances have chemical reactivity and mutagenicity
  similar to acetaldehyde and malonaldehyde. Therefore, NIOSH recommends that careful consideration should be given
  to reducing exposures to these nine related aldehydes.

     Further information can be found in the "NIOSH Current Intelligence Bulletin 55: Carcinogenicity of Acetaldehyde
  and Malonaldehyde, and Mutagenicity of Related Low-Molecular-Weight Aldehydes"  [DHHS (NIOSH) Publication
  No. 91-112.]

  Asbestos

     NIOSH considers asbestos to be a potential occupational carcinogen and recommends that exposures be reduced to
  the lowest feasible concentration. For asbestos fibers >5 micrometers in length, NIOSH recommends a REL of 100,000
  fibers per cubic meter of air (100,000 fibers/m3), which is equal to 0.1 fiber per cubic centimeter of air (0.1 fiber/cm3),
  as determined by a 400-liter air sample collected over 100 minutes in accordance with NIOSH Analytical Method
  #7400. Airborne asbestos fibers are defined as those particles having (1) an aspect ratio of 3 to 1 or greater and (2) the
  mineralogic characteristics (that is, the crystal structure and elemental composition) of the asbestos minerals and their
  nonasbestiform analogs. The asbestos minerals are defined as chrysotile,  crocidolite, amosite (cummingtonite-
  grunerite), anthophyllite, tremolite, and actinolite. In addition,  airborne cleavage fragments from the nonasbestiform
  habits of the serpentine minerals antigorite and lizardite, and the amphibole minerals contained in the series
  cummingtonite-grunerite, tremolite-ferroactinolite, and glaucophane-riebeckite should  also be counted as fibers
  provided they meet the criteria for a fiber when viewed microscopically.

     As found in 29 CFR 1910.1001, the OSHA PEL for asbestos fibers (i.e., actinolite asbestos, amosite, anthophyllite
  asbestos, chrysotile, crocidolite, and tremolite asbestos) is an 8-hour TWA airborne concentration of 0.1 fiber (longer
  than 5 micrometers and having a length-to-diameter ratio of at least 3 to  1) per cubic centimeter of air (0.1 fiber/cm3),
  as determined by the membrane filter method at approximately 400X magnification with phase contrast illumination.
                                                   o
  No worker should be exposed in excess of 1 fiber/cm (excursion  limit)as averaged over a sampling period of 30
  minutes.

  Benzidine-, o-Tolidine, and o-Dianisidine-based Dyes

     In December 1980, OSHA and NIOSH jointly published the Health Hazard Alert: Benzidine-, o-Tolidine-, and  o-
  Dianisidine-based Dyes.

     In this Alert, OSHA and NIOSH concluded that benzidine  and benzidine-based dyes were potential occupational
  carcinogens and  recommended that worker exposure be reduced to the lowest feasible level.

     OSHA and NIOSH further concluded that o-tolidine and o-dianisidine (and dyes based on them) may present a
  cancer risk to workers and should be handled with caution and exposure minimized.

  Carbon Black

     NIOSH considers "Carbon Black" to be the material consisting of more than 80% elemental carbon in the form  of
  near-spherical colloidal particles and coalesced particle aggregates of colloidal  size that is obtained by the partial


file:///P|/PDF_Harvest/SentFromJeannie/2014ORD_CDProject/625c04015/Content/nengapdx.htm[5/30/2014 10:42:07 AM]

NIOSH/Appendices to Online NIOSH Pocket Guide to Chemical Hazards

  combustion or thermal decomposition of hydrocarbons.

     The NIOSH REL (10-hour TWA) for carbon black is 3.5 mg/m3. Polycyclic aromatic hydrocarbons (PAHs),
  particulate polycyclic organic material (PPOM), and polynuclear aromatic hydrocarbons (PNAs) are terms frequently
  used to describe various petroleum-based substances that NIOSH considers to be potential occupational carcinogens.

     Since some of these aromatic hydrocarbons may be formed during the manufacture of carbon black (and become
  adsorbed on the carbon black), the NIOSH REL (10-hour TWA) for carbon black in the presence of PAHs is also 0.1
  mg PAHs/m3 (measured as the cyclohexane-extractable fraction).

     The OSHA PEL (8-hour TWA) for carbon black is 3.5 mg/m3.

  Chloroethanes

     NIOSH considers ethylene dichloride; hexachloroethane; 1,1,2,2-tetrachloroethane; and 1,1,2-trichloroethane; to be
  potential occupational carcinogens.

     Additionally, NIOSH recommends that the other five chloroethane compounds:

        • 1,1-dichloroethane
        • ethyl chloride
        • methyl chloroform
        • pentachloroethane
        • 1,1,1,2-tetrachloroethane
  be treated in the workplace with caution because of their structural similarity to the four chloroethanes shown to be
  carcinogenic in animals.

  Chromic Acid and Chromates (as 003), Chromium(II) and Chromium(III) Compounds (as Cr), and
  Chromium Metal (as Cr)

     The NIOSH REL (10-hour TWA) is 0.001 mg Cr(VI)/m3 for all hexavalent chromium [Cr(VI)] compounds.
  NIOSH considers all Cr(VI) compounds (including chromic acid, tert-butyl chromate, zinc chromate, and chromyl
  chloride) to be potential occupational carcinogens.

     The NIOSH REL (8-hour TWA) is 0.5 mg Cr/m3 for chromium metal and  chromium(II) and chromium(III)
  compounds.
     	                              o
     The OSHA PEL is 0.1 mg CrO3/m  (ceiling) for chromic acid and chromates (including tert-butyl chromate with a
  "skin" designation and zinc chromate);  0.5 mg Cr/m  (8-hour TWA) for chromium(II) and chromium(III) compounds;
  and 1 mg Cr/m (8-hour TWA) for chromium metal and insoluble salts.

  Coal Tar Pitch Volatiles

     NIOSH considers coal tar products  (i.e., coal tar, coal tar pitch, or creosote) to be potential occupational
  carcinogens; the NIOSH REL (10-hour TWA) for coal tar products is 0.1 mg/m3 (cyclohexane-extractable fraction).
     	                     	                                        o
     The OSHA PEL (8-hour TWA) for coal tar pitch volatiles is 0.2 mg/m  (benzene-soluble fraction). OSHA defines
  "coal tar pitch volatiles" in 29 CFR 1910.1002 as the fused polycyclic hydrocarbons that volatilize from the distillation
  residues of coal, petroleum (excluding asphalt), wood, and other organic matter and includes substances such as
  anthracene, benzo(a)pyrene (BaP), phenanthrene, acridine, chrysene, pyrene, etc.

  Coke Oven Emissions

-------
NIOSH/Appendices to Online NIOSH Pocket Guide to Chemical Hazards


      The production of coke by the carbonization of bituminous coal leads to the release of chemically-complex
  emissions from coke  ovens that include both gases and particulate matter of varying chemical composition.

      The emissions include coal tar pitch volatiles (e.g., particulate polycyclic organic matter [PPOM], polycyclic
  aromatic hydrocarbons [PAHs], and polynuclear aromatic hydrocarbons [PNAs]), aromatic compounds (e.g., benzene
  and beta-naphthylamine), trace metals (e.g., arsenic, beryllium, cadmium, chromium, lead,  and nickel), and gases (e.g.,
  nitric oxides and sulfur dioxide).

  Cotton Dust (raw)

     NIOSH recommends reducing exposures to cotton dust to the lowest feasible concentration to reduce the
  prevalence and severity of byssinosis; the REL is <0.200 mg/m3 (as lint-free cotton dust).

      As found in OSHA Table Z-l (29 CFR 1910.1000), the PEL for cotton  dust (raw) is 1 mg/m3 for the cotton waste
  processing operations of waste recycling  (sorting, blending, cleaning, and willowing) and garnetting.

     PELs for other sectors (as found in 29 CFR 1910.1043) are 0.200 mg/m3 for yarn manufacturing and cotton
                               o
  washing operations, 0.500 mg/m  for textile mill waste house operations or for dust from "lower grade washed cotton"
  used during yarn manufacturing, and 0.750 mg/m3  for textile slashing and weaving operations.

      The OSHA standard in 29 CFR 1910.1043 does not apply to cotton harvesting, ginning, or the handling and
  processing of woven  or knitted materials  and washed cotton.

      All PELs for cotton dust are mean concentrations of lint-free, respirable cotton dust collected by the vertical
  elutriator or an equivalent method and averaged over an 8-hour period.

  Lead

     NIOSH considers "Lead" to mean metallic lead, lead oxides, and lead salts (including organic salts such as lead
  soaps but excluding lead arsenate).

      The NIOSH REL for lead (8-hour TWA) is 0.050 mg/m3;  air concentrations should be  maintained so that worker
  blood lead remains less than 0.060 mg Pb/100 g of whole blood.

      OSHA considers  "Lead" to mean metallic lead, all inorganic lead compounds (lead oxides and lead salts), and a
  class of organic compounds called soaps; all other lead compounds are excluded from this definition.

      The OSHA PEL (8-hour TWA) is 0.050 mg/m3; other OSHA requirements can be found  in 29 CFR 1910.1025.
  The OSHA PEL (8-hour TWA) for lead in  "non-ferrous foundries with less than 20 employees"  is 0.075 mg/m3.

  Mineral  Dusts

      These OSHA PELs for "mineral dusts"  listed below are from Table Z-3 of 29 CFR 1910.1000.

      The OSHA PEL (8-hour TWA) for crystalline silica (as respirable quartz) is either 250  mppcf divided by the value
  "%SiO2 + 5" or 10 mg/m3 divided by the value "%SiO2 + 2".

      The OSHA PEL (8-hour TWA) for crystalline silica (as total quartz) is 30 mg/m3 divided by the value  "%SiO2 +
  2".

      The OSHA PELs  (8-hour TWAs) for cristobalite and tridymite are the values calculated above using the count or
  mass formulae for quartz.

-------
NIOSH/Appendices to Online NIOSH Pocket Guide to Chemical Hazards

     The OSHA PEL (8-hour TWA) for amorphous silica (including diatomaceous earth) is either 80 mg/m3 divided by
  the value "%SiO2M, or 20 mppcf.

     The OSHA PELs  (8-hour TWAs) for mica, soapstone, and talc (not containing asbestos) are 20 mppcf.

     The OSHA PEL (8-hour TWA) for Portland cement is 50 mppcf. The OSHA PEL (8-hour TWA) for graphite
  (natural) is 15  mppcf.

     The OSHA PEL (8-hour TWA) for coal dust (as the respirable fraction) containing less than 5% SiO2 is 2.4
  mg/m3.

     The OSHA PEL (8-hour TWA) for coal dust (as the respirable fraction) containing greater than 5% SiO2 is 10
  mg/m3 divided by the value "%SiO2 + 2".

  NIAX® Catalyst ESN

     In May 1978, OSHA and NIOSH jointly published the Current Intelligence Bulletin (CIB) 26: NIAX® Catalyst
  ESN.

     In this CIB, OSHA and NIOSH recommended that occupational exposure to  NIAX® Catalyst ESN, its
  components, dimethylaminopropionitrile and bis(2-(dimethylamino)ethyl)ether, as well as formulations containing
  either component, be  minimized.

     Exposures  should be limited to as few workers as possible, while minimizing workplace exposure concentrations
  with effective work practices and engineering controls.

     Exposed workers  should be carefully monitored for potential disorders of the nervous and genitourinary system.
  Although substitution is a possible control  measure, alternatives to NIAX® Catalyst ESN or its components should be
  carefully evaluated with regard to possible adverse health effects.

  Trichloroethylene

     NIOSH considers trichloroethylene (TCE) to be a potential occupational carcinogen and recommends a REL of 2
  ppm (as a 60-minute ceiling) during the usage of TCE  as an anesthetic agent and 25 ppm (as a 10-hour TWA) during
  all other exposures.

  Tungsten Carbide (Cemented)

     "Cemented tungsten carbide" or "hard metal" refers to a mixture of tungsten  carbide, cobalt, and sometimes metal
  oxides or carbides and other metals (including nickel).

     When the cobalt (Co) content exceeds 2%, its contribution to the potential hazard is judged to exceed that of
  tungsten carbide.

     Therefore,  the NIOSH REL (10-hour TWA) for cemented tungsten carbide containing  >2% Co is 0.05 mg Co/m ;
  the applicable OSHA PEL is 0.1 mg Co/m3 (8-hour TWA). Nickel (Ni) may sometimes be used as a binder rather than
  cobalt.

     NIOSH considers cemented tungsten carbide containing nickel to be a potential occupational  carcinogen and
  recommends a REL of 0.015 mg Ni/m3 (10-hour TWA).

     The OSHA PEL for Insoluble Nickel (i.e., a  1 mg Ni/m3 8-hour TWA) applies to mixtures of tungsten carbide and
  nickel.

                   SUBSTANCES WITH NO ESTABLISHED RELs

     After reviewing available published literature, NIOSH provided comments to OSHA on August 1, 1988, regarding
  the "Proposed Rule on Air Contaminants" (29 CFR 1910, Docket No. H-020).

     In these comments, NIOSH questioned whether the PELs proposed (and listed below) for the following substances
  included in the Pocket Guide were adequate to protect workers from recognized health hazards:

       •  acetylene tetrabromide [TWA 1 ppm]
       •  chlorobenzene [TWA 75 ppm]
       •  coal dust (<5%SiO2) [2 mg/m3 (as the respirable dust fraction)], coal dust (>/= 5% SiO2) [0.1 mg/m3
       (as the respirable quartz fraction)]
       •  ethyl bromide [TWA 200 ppm; STEL 250 ppm]
       •  ethylene glycol [Ceiling 50 ppm]
       •  ethyl ether [TWA 400 ppm; STEL 500 ppm]
       •  fenthion [TWA 0.2 mg/m3 (skin)]
       •  furfural [TWA 2 ppm (skin)]
       •  2-isopropoxyethanol [TWA 25 ppm]
       •  isopropyl acetate [TWA 250 ppm; STEL 310 ppm]
       •  isopropylamine [TWA 5 ppm; STEL 10 ppm]
                                  	           o
       •  manganese tetroxide (as Mn) [TWA 1 mg/m ]
       •  molybdenum (soluble compounds as Mo) [TWA 5 mg/m3]
       •  nitromethane [TWA 100 ppm]
       •  m-toluidine [TWA 2 ppm (skin)]
       •  triethylamine [TWA 10 ppm; STEL 15 ppm]

     At that time, NIOSH also conducted a limited evaluation of the literature and concluded that the documentation
  cited by OSHA was inadequate to support the proposed PEL (as an 8-hour TWA) of 10 mg/m3 for alpha-alumina,
  benomyl, emery, glycerine (mist), graphite (synthetic), magnesium oxide fume,  molybdenum (insoluble compounds as
  Mo), particulates not otherwise regulated, picloram, and rouge.

                               MISCELLANEOUS NOTES

  Benzene: The final OSHA Benzene standard in 1910.1028 applies to all occupational exposures to benzene except
  some subsegments of industry where exposures are consistently under the action level (i.e., distribution and sales of
  fuels, sealed containers and pipelines, coke production, oil and gas drilling and production, natural gas processing, and
  the percentage exclusion for liquid mixtures); for the excepted subsegments, the benzene limits in Table Z-2 apply
  (i.e., an 8-hour TWA of 10 ppm, an acceptable ceiling of 25 ppm, and 50 ppm for a maximum duration of 10 minutes
  as an acceptable maximum peak above the acceptable ceiling).
