I. fl TRODUCTION
A. GENERAL
This manual is intended to providethe basis for comprehensive
safety programs in each NEIC activity consistent with the
Occupational Safety and Health Act requirements. Obviously, every
safety hazard cannot be anticipated. Thus, rules cannot be developed
for every contingency that could arise. Consequently, a practical
safety program consists partly of rules and adherence thereto and
partly of common sense, judgment, and experience. All employees
are, therefore, required to enforce and adhere to the published
rules, but, more importantly, are required to maintain a high level
of safety consciousness. The latter involves constant vigilance
for unsafe or potentially hazardous practices and immediate correc-
tive action as necessary to ameliorate the condition.
Branch chiefs are responsible for the execution or incorporation
of any changes or amendments made to this manual as the need is perceived.
Requests are to be submitted, in writing, to the Safety Officer.
In all considerations related to the safety, two aspects tran-
scend all others:
1. Safety consciousness is paramount to all other consider-
ations in the, course of job—related activities at NEIC. When
in doubt regarding the safety aspects of a particular task or activity

-------
2
and when competent advice is not immediately available, it is man-
datory to follow the safest course of action.
2. Our human resources are our most priceless asset. The
prevention of loss of life, injury, or health hazard is the greatest
responsibility that we share,
B. IMPLEMENTATION RESPONSIBILITIES
Responsibilities are assigned for implementation of the
safety requirements set forth in this manual. A description
of each individual’s responsibilities is presented.
Director, NEIC
The Director is responsible for the overall effectiveness of
the NEIC Safety Program. Working through the Center Safety Officer
he ensures that all NEIC employees are working in the safest possible
environment.
Center Safety Officer
The Center Safety Officer is responsible for the overall coordi-
nation of the Safety Program. In cooperation with the Center
Laboratory Safety Coordinators, Field Safety Coordinator, and with
Branch Chiefs, he coordinates and maintains a safety program to identify
possible hazards, disseminates information on known hazards, follows up
on corrective action recommended, and coordinates the NEIC safety
training program.

-------
3
Laboratory Safety Coordinators and Field Safety Coordiflator
These people are responsible for identifying possible hazards
and recoumiending. corrective action to be taken by Branch Chief or
first line Supervisors. They. hold periodic safety train ng sessions
for Branch personnel, disseminate safetyinformation on new safety
procedures, equipment, etc.,routinely inspect laboratories, review
field safety procedures, and follow up to ensure that recommendations
are implemented.
Branch Chiefs
Branch Chiefs are responsible as line managers. for the safety
and security of employees, equipment, and areas assigned to them;
ensuring that proper safety equipment is provided where needed.
Working through direct supervision and through first—line supervisors, the
Branch Chiefs ensure that all aspects of the Safety Program are being
carried out in their branch.
First Line Supervisors . .
First line supervisors are responsible for ensuring that, the
day—to—day work being carried out under their supervision in the
laboratories and in the field is accomplished in accordance with
established NEIC safety rules and policy. They are responsible for
insuring that employees perform their jobs in a safe manner and for
initiating immediate corrective action as soon as’an.unsafe situation.
or procedure is observed.

-------
4
NEIC Safety. Committee
rhe Safety Committee is made up of the Center Safety Of ficer,
Field Safety Coordinator, Laboratory Safety Coordinators, and
Branch Chiefs. The committee is responsible for reviewing and/or
investigating serious accidents and recommending corrective action.

-------

II. GENERAL SAFETY PRECAUTIONS
A. All employees are directed to brLng to the attentionof he
most readily accessible supervisor any condition, practice, or
circumstance that could result in health hazard, injury, or
death to any employee. When imminent hazards exist, any employee
on the scene must take steps to eliminate the hazard. Follow—up
consultation with Branch Chiefs or Management should be carr{ed out
at the first opportunity. In cases where the hazard is not of
an imminent nature the supervisor or employee is expected to
consult Branch Chief or Management regarding appropriate corrective
measures. Application of this rule requires the exercise of
good judgment and common sense.by all employees.
B. Protective headwear, eyewear, footwear, clothing, and accessOries
are available for all foreseeable circumstances; their use, as
appropriate, is mandatory. Ifindoubt, act on the part of safety.
C. Branch Chiefs are authorized and directed to counsel individual
employees about any work habits and practices that could be a
hazard to the individual employee or fellow employees. Continued
or repetitive failure to heed such counseling will be construed to
be uncooperative conduct and may lead to appropriate administrative
action.

-------
6
D. Supervisory and Management personnel are required to familiarize
themselves with the regulations promulgated pursuant to the
Occupational Safety and Health Act of 1970. The latest regulations)
set forth in the Federal Register, are available through the
Safety Officer.
E. The following practices are expressly forbidden:
use of explosives (as defined by 49 Chapter I) for any
purpose whatsoever, except with the specific written
approval of the Director.
— ignition of flammable liquids within, on,or through
improvised heating devices (barrels) etc., space
heaters not having Underwriters Laboratories’ approval.
— entry — — in the absence of clear evidence that such entry.
can be accomplished safely, into areas or spaces wherein
toxic or explosive concentrations of gases or dust°majr
exist.
F. Visitors to all work areas other than offices shall be escorted•
by an employee. The escorting employee is responsible for
the safety of the visitor until relieved of the responsibility
by a supervisor, Branch Chief, or Management personnel, or
until the visitor departs the work area.

-------
C. All employees having duties that could require prolonged ex-
posure to cold weather are directed to become thoroughly
familiar with the contents of the publication “Survive in
Winter, t ’ appended to this manual [ Appendix Aj.
H. All employees whose duties could cause them to undertake
field work are encouraged to avail themselves of immunization
for typhoid fever, tetanus, Rocky Mountain spotted fever and
polio.
I. All employees will receive basic first aid training. Such
training will be provided by NEIC at the earliest opportunity.

-------
9
III. OFFICE SAFETY RULES
A. The Safety Officer will prepare and post, proininéntiy throughout.
the building, an evacuation plan for all of the area in Building
53 occupied by NEIC. Employees are directed to familiarize
themselves with the plan and to be prepared to execute the plan
at any time. An evacuation drill will be scheduled periodically.
B. All employees are cautioned to wipe feet when entering the
building and to clean up spilled liquids promptly.
C. The Xerox machine is both a shock and burn hazard to persons
not trained in the proper maintenance procedures. The practice
of wedging or jamming control buttons is particularly hazardous
and ‘is not permitted. A Key Operator is to be called in the
case of any machine malfunction. In the event of a fire in
the machine, an attempt should be made to unplug the machine.
,The door of the Xerox room should then be closed and the fire
department called. ‘
D. All electrical’ devices, except clocks (and laboratory equipment —
discussed elsewhere herein) are to be turned off, when not in
use. Coffee pots must be unplugged at the closeóf business
each day.
E. “ When an electrical circuit breaker is tripped, the. èause should
be traced and cheèked for fire or electrical shock hazard and
remedied before the, circuit is reactivated. .

-------
10
F. Bookcases stacked four units or higher shall be attached
to the wall.

IV LABORATORY SAFETY RULES
A. GENERAL SAFETY PRACTICES
1. Bottle carriers should be used when transporting glass
bottles containing hazardous themicals (acids or other
corrosive liquids), fla nable liquids, or any large glass
bottles (distilled water bottles).
2. All containers of chemicals and samples shall be labeled
clearly and correctly. All unlabeled materials, must be
discarded under the direction of a supervisor.
3. Chemicals are not to be pipetted by mouth,
4. All gas cylinders must be firmly secured individually, by
means of safety clamps and straps or chains.
5. All electrical equipment should be properly grounded,,
and electrical cor4s inspected periodically to en-
sure that they are.in good working condition.
6. Damaged glassware ‘should never be used in the laboratory.
Cracks or jagged edges are. a. serious hazard. All such Items
should be set aside to;be repaired if they are worth salvaging.
* For purposes of this manual the same procedures will ‘generally apply
to both mobile— and main—laboratory spaces. ‘

-------
If not, they should be discarded in such away that people
removing waste material will not be injured.
7. Joints, stópèocks, •etc., are not leak proof, and pro
visions should be included for catching any matérial that
could leak out. This is particularly true when leaving
a reaction unattended.
8. Where possible, heating mantles are pref erred over open
flames or Shot plates. :
9. Warning signs meetlng’OSHA specifications shall be used as
required. They should be removed when’the hazardháabéen
corrected or no longer exists.
10. Floors and surface working areas (benches, tables, etc.) are
tobe kept’ clean, dry, and free from éorrôsive chemicals.
Spills of any liquid, powdered or granular material must be
cleaned up it m ediately.
11. Instruments, glassware, equipment, reagents, and unused con-
tainers must be stored in designated areas when not in use.
Aisles, hallways, and walkways are to be kept clear and
well—lighted.
12. Initiation of a laboratory ánalyèis or experiment, not fully de—
scribed in Standard Methods, AQC Manual, or other authoritative

-------
13
procedural source, must be preceded by a survey, of
existing literature. The toxicity and other hazards
connected with the reactants and products should be in-
vestigated’ thoroughly before starting any laboratory
action. The effects of impurities on the safety
aspects of the proposed reaction should be considered.
13. The safety of other personnel in the laboratory must be
considered as well as the’ safety ‘of the persQn running
the reaction. Before undertaking any non—standard an-
alytical procedures, other personnel’ must be made cog-
nizant of the nature of the analysis to be carried out.
14. Prior to re1inquishin control of a non—standard or
otherwise hazardous analysis, the employee assuming con-
trol must be thoroughly Instructed in ‘the potential’haz—
ards and methods of counteracting such hazards .
15., Any analysis not completely described in the reference
literature must be run on a small scale before attempting
full—laboratáry scale reaction. During this phase of’ the
experimentation, the analysis should be presumed hazardous
and the pertinent items of individual safety equipment
used until the reaction is demonstrated to be non—hazardous.
16. Equipment for the analysis must be chosen with the chemistry
and’ physics of the reaction in mind, e.g., fluorination in

-------
14
glass equipment is inherently dangerous as is the use of
flat—bottomed equipment in pressure and vacuum reactions.
17. Class equipment should be assembled carefully to avoid
strains brought about by increased temperature and vibra-
tions. Ball joints give greater freedom of movement than do
standard tapered joints.
18. Any vactium, pressure, or high—temperature distillation
should be considered potentially hazardous, and •the proper
safety equipment such as safety shields should be used..
19. Sufficient free—board should be allowed when sizing equip-
ment to allow for liquid expansion due to increased tem-
perature. This is particularly true in non—glass equ ipment
when the volume of the reactants cannot be observed during
all phases of the reaction.
20: It should be remembered that ti le high—boiling components
tend to concentrate in the itill pot, and many substances
which are non—hazardous in a dilute concentration can be
very hazardous In concentrated forms.
21. With temperature—sensitive material, it should be remembered
that when adding heat to . a reaction the temperature of the
s. rface of the vessel may he considerably higher than the
- temperature of the reaction mass in which case it may be
advisable to use a controlled temperature bath or a heating
ma ntle.

-------
15
B. PERSONAL SAFETY RULES — LABORATORY
1. Always use rubber gloves and face mask when transferring
large amounts (1 liter or more) of corrosive liquids..
2. Safety glasses are mandatory for employees and visitors
in all laboratory areas designated.
3. Face shields, rubber and asbestos gloves, aprons and smocks
are to be worn when appropriate.
4. Safety shoes are required for employees who work in areas
where large or heavy equipment and containers are used.
Branch Chiefs will, prescribe personnel and areas to which
this rule applies.
5. All employees using. illuminated microscopes must be properly
trained in the use of filters for eye protection.
6. Employees using UV disinfection devices shall wear proper
eye protection.
7. All employees required.to use equipment producing steam or
‘hot water (1.e., water still, dishwasher, autoclave, etc.)
will be properly trained.

-------
16
8. Heavy leather—f aced gloves or other approved hand protection
shall be used to free stuck stoppers, caps, or lids from
glass containers and when inserting or removing glass tubing
from rubber stoppers.
9. All personnel shall be instructed, as required, on the location
and use of first—aid kits, fire, extinguishers, safety showers,
eye baths, fire bl?nkets, and emergency’ oxygen equipment.
Operational readiness of all such equipment shall be ascertained
by inspection; then equipment shall be certified, in writing,
as operationally ready, by the NEIC Safety Of fiçer.or his
designee.
10. Consumption of food and beveragesand smoking in laboratories
is prohibited.

-------
17
11. Every employee shall be instruc ed regarding the following:
a. Location of fire alarms;
b. Telephone numbers of the Denver Federal Center Fire
-Department and Ambulance Service, immediate, supervisor,
Branch Chief, Assistant Directors and Director;
c. Notifications to be made in the event of emergencies;
d. Other safety precautions as warranted.
C. USE AND HANDLING OF HAZARDOUS MATERIALS
1. Compressed Gases
a. Classifications
Compressed gases are classified in four groups. While
“non—toxic’ is part of two of these classifications, it
mustbe remembered that such gases act as simple asphyx—
lants when they reduce the oxygen concentrationsbelov
safe levels.
(1)’ Group I —— Non—Flammable, Non—Toxic Gases
Genetrons* except 142B, l5lA, ll32A
(flammable)
Carbon Dioxide
Nitrogen
Nitrous Oxide
Inert Gases (Helium, Neon, etc.)
Oxygen - no limit consistent with usage.
Oxygen should be stored away from readily
oxidized materials.
* Brand name of liquified fluorinated hydrocarbons manufactured by
Specialty Chemicals Division, Allied Chemical Corp.

-------
18
(2) Group II —— Non—Flanunable, Toxic Gases
Boron Trichioride
Boron Trifluoride
Chlorine
Fluorine
Hydrogen Chloride
Hydrogen Fluoride
Nitrogen Tetroxide
Phos gene
Sulfur Dioxide
Group—I l gases can be expected to cause serious effects
on human beings in relatively small concentrations. While
these gases are not flaimnable, most cylinders are equipped
with fusable’ plugs operating at 160—165°F. Exposure ..to
f ire could cause release of gases. Cylinders should be
stored under sprinkler protection, and cylinder. size should
be No. 3 or smaller when used In the laboratories. Cylinders
within laboratories should be kept within hoods with the.
exhaust running at all times Unless gas. has some distinc-
tive warning odor within a safe concentration, suitable
leakage detectors must be employed.
(3) Group III —— Flammable, Toxic Cases
Aimnonia
Carbon Monoxide
Dimethylamine
Ethylene Oxide
Hydrogen Sulfide
Methyl Chloride
Trimethyiami’ne

-------
19
In addition to the toxic properties exhibited by the gases
in Group II, these gases are flammable. Precautions.as
outlined for the Group—IT gases should be followed and, in
addition, gases inside laboratories should be restricted
to those areas where Class I, Division I, electrical equip-
ment is provided. Open flames and other sources of ig-
nition must be avoided. Electric heating mantles within
hoods may be used provided controls are located outside
the hoódèd area.
(4) Group IV — Flammable, Non—Toxic Gases
Acetylene
Alkanes, Methane, Ethane, Propane, Butane
Alkenes, Ethylene, Propylene; Butylenes, etc.
Butadiene
Ethyl Chloride
Hydrogen
Vinyl Chloride
Cylinder size for Group—TV gases should be No. 2 or smaller.
Cylinders should be stored under sprinkler protection, and
electrical equipment should be suitable for Class I,
Division I, locations. For larger usages, see comments
under Group II and III.
b. Procedures
Regulators designed for the particular gas are required
for most materials. Some cylinders in which liquified
contents have vapor pressures under 15 psig at 68°F can
be equipped with needle valves to regulate the flow.’

-------
20
Cocks, gate,, or. Iobe valves must be avoided. For high—
pressure gases, two—stage regulators should be used when
delivery pressures below 5 psig are required
Connecting hose, tubing, etc.,inust be suitable for use with
the gas involved and are tobe protected from impact or me-
chanical damage.
Since compressed gases vary widely in their physical char-
acteristics, chemical activity, toxicity, flan ability, etc.,
the foregoing should be éonsidered a general guide. Each
gas must be evaluated on its own.merits, and a safe-handling
procedure followed. A valuable source of information is the
Matheson Gas Data Book available from the Matheson Company, Inc.,
East Rutherford, New Jersey.
When not in use, valves must be closed and caps replaced.
All cylinders, active or inactive, must be properly supported
to prevent toppling or Ea1lin .
Insofar as is possible, only one cylinder of either Group II,
III or IV should be placed in any one hood.

-------
21
Oxidizing and flammable gases shall be separated in storage.
Incompatible laterials shall not be placed in close proximity
to one another [ see Appendix B].
Venting of gas cylinders is prohibited —— no exceptions.
All cylinders not in use shall bear a tag or label showing.
status (full, partially used, depleted, etc.).
Cylinders may be moved only with the approved cylinder cart.
Tie—down straps or chains must be used to secure the cylinder
to the cart.
Empty and full cylinders shall not be stored together.
Expended cylinders shall be removed from service with positive
pressure remaining.
Cylinders must be off at the close of each day, except
when expressly authorized by a branch chief or supervisor.
Cylinders of compressed gases must b stored valve end up
in racks to prevent faIling.

-------
22
Cylinders should always be kept away from sources of heat
such as steam lines, radiators, or direct rays of the sun.
Only the cylinders required fo.r immediate use are to remain
in the laboratory work area. All cylinders not in use must
be moved to a separate storage area promptly following use.
c. Care and handling of Compressed Gas Regulators
In the use of gas regulators there are specific rules that
must be followed because of the potentialdanger associated
with the high pressures involved. The following section.
covers general information and the proper procedures for
using regulators:
(1) There are two couu ion kinds of regulators, single stage and
two stage. •The two—stage regulator is recommended for. sev—.
eral reasons. These regulators deliver a constant:pressure
over the whole range of cylinder pressure, and an added
safety feature assures longerdiaphragm life because of a
preset safety that prevents overloading of the first stage.
(2) Gas cylinder regulators are manufactured with different limits
on the diaphragms for low—pressure delivery. Delivery pres-
sure is approximately half of the low—pressure gauge maximum.
(3) Regulators are equipped with specific fittings prescribed by.
the Cylinder Gas Association, and progress has been made in
recent years to standardize the kind of fitting used for each

-------
23
type of gas. Different fittings are still used by different
vendors. Therefore, the operator must be familiar with the
type of CGA fitting being used’ by the’vendor supplying him
with gas. The following CGA fittings are used by EIC’s’current
vendor for the common gases:
Kind’ of Fittin,
Nitrogenh > CGA—580
Helium )
Air (breathing) CCA—1340
Hydrogen
P—5 CGA—350
P—b
Oxygen CGA-540
Acetylene CGA—510
Nitrous Oxide CGA—1320
(4) No sort of sealing compound or, teflon tape should be used to
stop leaks at the cylinder valve connection. If a leak per-
sists at the valve, the cylinder valve seat is probably at
fault. The cylinder should be returned to the vendor.
(5) The following step—by—step procedure should always be followed
when shutting off a cylinder for any purpose:
a) Close cylinder valve completely.
b) Allow gas to flow through the regulator until both high—
and low—pressure gauges register zero; ‘
c) Turn the regulator—adjusting, screw counterclockwise until
the screw is loose; and ,
d) Close the regulator needle valve. (Most, but not all,
regulators are equipped with needle valves.)

-------
24
(6) Thefollowing step—by—step procedure should ‘always be followed
when turning on’a cylinder’:
a) Check to make sure the needle valve is ‘closed.
b) Check the regulator—adjusting screw to make sure it is
turned counter—clockwise until loose;
c) Slowly and carefully open the cylinder valve untIl the
full pressure is registered on the high pressure gauge;
d) Then open the valve cottLpletely;
e) Open the needle valve;
f) Turn the pressure—adjusting screw clockwise slowly until
the desired pressure is registered on the low—pressure gauge,
(7) The pressurized’system should always be checked’forleaks, par-
ticularly the’ high—pressure side. This can be done quickly by
turning the regulator adjusting screw counterclockwise and the
cylinder valve of f. The pressure should remain’constant; a
rapid drop in pressure iüdicates a substantial leak. An alter-
native method is the use of an inert’ liquid leak detector, such
as “Snoop,” which discovers small leaks and does not require
the interruption of the gas’ flow.
(8) No oil or lubricant should be used on, any regulator especially
‘one In oxygen service.
(9) All metal lines connected to regulators must be disconnected
befOre changing cylinders.
(10) No connection from a gas cylinder to the high—pressure side of

-------
25
a regulator should ever be made employing metal or flexible
tubing,.unless the connecting material, is approved f or high
pressures.
(11) The cylinder’ valve seat should always be checked for clêanli—
ness before installing a regulator and, If dirty, should be
wiped with a dry tissue.
(12) Regulators have both left— and right—handed threads for con-
nections, but it Is easy to differentiate between them. The
left—handed thread will always have a V—shaped notch in the
metal connecting nut.
(13) Adaptors are readily available to change the usage of a regu—
lator from one gas to another, but this is not recommended.
This practice introduces an additional connection where an-
other failure or leak could occur. Another and more serious
possibility is subjecting a regulator to contac.t with a
corrosive gas when the regulator is designed only for inert gas.
2. F].immablE Llquidá
a. Classification
Class I Closed cup flash point below 43°C (110°F)
Class II Closed cup flash point of 43°C (110°F) and higher*
b. Procedures
Flammable liquids must never be handled’ in the vicinity of
* See Appendix B for flash points of sdmeconunon materials.

-------
26
open flames or sparking electrical equipment. Air cur-
rents could blow a. stream of vapors to the flame, resulting
--in a flashback followed by fire or explosion. Diethyl ether
and carbon disulfide are particularly dangerous in this
respect. The latter is so highly flammable that it may
catch fire upon contact with hot water or a -steam radiator.
Ether viii ignite in contact with a hot plate. In a distil-
lation always use a water bath,for these liquids must never
be distilled over an open flame.
Toluene, acetone, benzene, petroleum ether, alcohols, and
many other flammable solvents must be handled with cautIon
and at a safe distance from open flames and open electrical
equipment. -
Materials containing flammable solvents muét not be dried
in an electrically heated ovenexceptthose expressly de— -
signed to be explosion—proof.
In dispensing flammable liquids from a drum, a hand pump
is preferred. If dispensing from a rack with the drum on
- its side, a self—closing valve must be provided. Flame—;
arresting bung vents and ground wires shall be. used when
dispensing from drums.

-------
27
Compressed air should never be used to dispense flammable
liquids.
Analyses or reactions involving, more than one liter of
Class—I material at higher than room temperatures must be
done in a laboratory hood.
No more than five liters of Class I materials can be used
in analyses or reactions in hoods.
Dse of Class—tI materials within 4.4cc f the flash
point of the material must be in laboratory hoods if the
quantity of material being handled exceeds one liter.
Transportation of flammable materials in excess of one
liter is to be in safety cans only.
Transfer of flammable liquids must be carried out in well
ventilated areas —— a fume hood ‘Is preferable.
Grounding straps shall be used to ground metal containers
when transferring flammable liquids from one metal con—
tamer t.o another. During such’ ‘transfer, only metal fun—’
nels shall’be used.

-------
28
Flammable liquids in use in open containers shall be kept
in fume hoods wherever possible.
c. Storage (Class I and Ii materials)
Safetycans up to one:—gal. capaèity should be stored in,
OSHA-approved flammable storage cabinets.
No more than five one—liter containers of Class I and II
material should be Stored in glass in the laboratory areas.
Open areas include open reagent shelves and bench tops
Storage should be distributed throughout the lab with no
more than two one—liter containers on each side of any
lab module.
Bulk storage of flammable liquids is permitted only In the
hazardous storage locker.
Bulk storage is permissible in drums or in safety cans up
to five—gal, capacity.
Drums are to be stored in the upright position except when
equipped with self-closing valves.
All :arums for diSpensing must be grounded, and con-
tainers also must be grounded to the drum when being
filled .

-------
29
3. Mercury
Mercury is not to be left in open containers, in sinks,
on bench tops or on the, floor if and when spilled.
While -the vapor pressure of mercury is relatively low
at room temperature, mercury is cumulative and, as such,
is an insidious and dangerous poison. Avoid splashing
mercury on hot surfaces as the resultant higher vapor
pressure increases the hazard.
Mercury spilled in lead—lined sinks and left there will
quickly form a lead amalgam that is acid soluble; a leak will
soon develop.
After cleaning up as much mercury with a vacuum jet or sponge
as possible,óne should then dust the residual amounts with
powdered sulfur.
4. Corrosive Materials
Severe burns can easily result from contact of strong acids,
alkalies, and other chemicals with the skin;
Protective clothing, such as aprons, full face shield, rubber
gloves, etc. ,.is to be worn when handling large quantities of

-------
such items as sodium hydroxide, sulfuric acid, nitric,, acid,
perchioric acid, hydrochloric acid,. glacial acetic acid., bro-
mine, etc;
Extreme care must be exercised to avoid splattering. Large
quantities of water should always be applied at once to ikin
surfaces exposed. to such burns;
Transfer of the strong chemicals shall be in or near sinks
where an adequate flow of water is running for rinsing spills
off hands, clothing, and equipment;
When diluting acids, the preferred method is to pour the acid
into water , slowly while stirring —— in order to dissipate the
heat. Never dilute acids by pouring water into concentrated
solutions. The heat generated could result in violent splat-
tering. This is especially true when using concentrated Sul-
furic acid. In diluting any concentrated acids the mixing
vessel should be in the sink or other confining container ——
‘in-order to prevent injury to the employee in the case of
breakage.
Concentrated. acids shall not be stored in the cabinet where
concentrated bases are kept.

-------
31
Storage of concentrated acids and bases is to be kept to I
minimum. Except when approved by the lab supervisor, two
gallons. per cabinet is the maximum which can be kept on hand.
Chromic acid shall not be stored or used inpipet washer jars
or other plastic containers.
Perchioric acid Is to be handled with extreme care. because it
inflicts a particularly painful, deep, and slow—healing burn.
Perchioric acid shall be stored and used only in a perchioric
acid hood. The hood shall be washed down after each use. A
dangerous explosion can result from failure to observe estab-
lished practices in handling perch lana acid.
All reagent bottles are to be rinsed thoroughly before being
discarded.
Containers are provided for carrying bottles that contain
strong acid or alkali.
Bottles or carboys of five—gIl. capacity must be handled and
stored in properly designed crates or other containers.
Such use will minimize breakage and also afford protection
to personnel.
5. Metallic Sodium and Potassium
Metallic sodium and potassium must be stored under kerosene

or petrolatum in tin cans. The cans should be inspected
periodically and replaced if evldeñcè of leaks or rusting
is found.
Scrap bits of metallic sodium and potassium should never be
discarded in the sink or thrown into the waste cans; reaction
with moisture will cause a fire, and violent splattering takes
place•. These metals should be added. care ful1y, in small
pieces, to cold alcohol. Wait until all gas evolution has
stopped. Sand solution is complete before adding more metal.
This alcoholate can then be discarded safely in the sink if
followed by washing with a generous flow of water.
6. Toxic Inorganic Substances
Inorganic solid materials seldom present a danger by
inhalation unless dusts are formed during opera tions with
the materials; therefore, these substances need not be
handled in fume hoods. If, however, dusts are formed or the
materials fumeupon heating, the operations should be performed
in a hood. Where, there is a possibility of breathing dusts,
suitable dust masks shall be worn.
The most common route of ingestion of inorganic toxic chemicals
is through the mouth. The habit of using gloves and washing

-------
33
hands with soap and water should preclude any possibility
of transferring materials from the hands to the mouth.
All spilled materials should be immediately cleaned up..
Inorganic toxic liquids or solutions should be treated the
same as toxic organic liquids or solutions.
Some inorganic poisons are:
Cyanides . Mercury, or its salts
Lead salts Silver nitrate
Selenium salts Ammonia
Arsenic compounds Fluorides
Halogens Beryllium, and its salts
Persons working with toxic inorganic compounds éhould
familiarize themselves with the dangers of the material and
proper methods of handling through searching the available
literature and consulting the laboratory supervisor or.
laboratory safety coordinator.
Hoods shall .be used for any operation which could give off
obnoxious odors or hazardous amounts of poisonous vapors.
This includes ash determinations, wet digestions with nitric
acid, boiling solutions of all volatile acids and ammonia,
and operations in which.any of the aforementioned poisonous
gases are used or produced. Hoods will be used for any
operations which give off a hazardous amount .of flammable vapors.

-------
34
7. Toxic Organic Compounds
Some organic compounds are highly toxic and dangerous because
of the many routes of incorporation into the body. Routes of
incorporation to guard against include: oral; inhalation;
skin absorption; and eye.absorption.
The number of potentially dangerous organic compounds is so
gr at that the safest rule to follow is to consider all such
materials to be dangerous. Some classes of organic compounds,
however, deserve particular attention:
Esters of Phosphoric Acids — — this group includes many highly
dangerous insecticides such as TEPP, Perathion, Phosdrin,
Azodrin, and Thimet. Also included in this group is
tricresyl phosphate, a gasoline additive. Most of these
compounds are liquids and are readily absorbed through
unbroken skin. Many also have sufficiently high vapor
pressure to pose a serious danger because inhalation of
• vapors at normal temperatures is likely.
Chlorinated alkanes and chlorinated aromatics — — this group
• alsoincludes many insecticide materials. Simple chlorinated
alkanes such as dichloromethane and chloroform are not highly
toxic, but prolonged exposure can lead to liver damage.
Carbon tetrachloride is highly dangerous to the liver, kidneys,
and lungs.

-------
35
Carbamates (urethanes ) ——most’ compounds in this group are
insecticides and should be considered’ highly toxic.
Nitro Compounds —— all organic nitro compounds are potentially
explosive, and’ many have severe physiological effects. Many
of the highly toxic nitro compounds (e.g. nitroanilines) ‘are rapidly
absorbed through the intact skin. They are also highly volatile
and present a danger because of being easily absorbed into the
body by inhalation.
E inines —— many amines, particularly aromatic amines, form
methemoglobin in the blood and thus reduce the blood’s,
ability to carry oxygen. Some’amines (e.g. napthylamine)
are carcinogenic.
Nitriles —— these compounds, of which acetonitrite is the
most familiar, have toxicological action similar to, but
less severe than, cyanide gas. When strongly heated these
compounds decompose to gaseous hydrocyanic acid.
Safety precautions required when using organic compounds should
include guarding against all routes of incorporation. Eye protection
should b’e worn at all times during handling ‘of organic. compounds
,because absorption through the mucous membranes in the eye is ,,,
extremely rapid, and a’small quantity is immediately presented
to the brain. Safety glasses should be considered minimum
protection when handling highly toxic materials.

-------
36
In order to protect against ingestion, mouth pipetting of
organic materials is forbidden. Also care should be exercised
to avoid the splashing of, concentrated solutions.
The best protection against Inhalation of volatile ‘toxic
substances is to perform all operations with those substances
in’ a’ fume hood. Weighing of pure ‘or concentrated pesticides
must also be performed in a hood.
Skin absorption usually occurs through contact with the hands:
therefore, the use of protective gloves is required when handling
toxic compounds as the pure materials or as concentrated
solutions. When gloves have been used they should be immedIately
washed with soap and water or discarded in waste receptacles
provided. Contaminated gloves shall not be left unattended.
Other protective aids against skin absorption include full—face
shields and protective aprons.
Before operations wi’th unfamiliar compounds are initiated
all available literature should be checked to assess the,
possible hazards, and preparation should ”be made accordingly.
Vessels containing highly toxic substances shall be kept in
beakers or similar containers to’ preclude the escape of
leaking material.

-------
37
8. Chemical Carcinogens ?
These procedures shall apply for all chemical carcinogens
regulated by the Department of Labor and will also be im-
•plemented for all other known or suspected chemical carcinogens.
The control practices include work procedures, environmental
control techniques and a health surveillance program. They are
specifically designed for work with chemical carcinogens, which
are both long—term hazards and immediate hazards, and supplement
conventional safety practices such as accident and fire prevention
included elsewhere in this manual.
The procedures set forth general safety principles to be
followed in the handling, storage and disposal of chemical
carcinogens. These standards have been prepared to minimize
hazards and to protect all persons in the laboratory area, and
to insure the sAfety of the surrounding community.
The National Cancer Institute, Department of Health, Education
nd Welfare is preparing and publishing a series of Carcinogen
Safety Monographs for 65 individual chemicals. DHEW reports that
18 monographs addressing 65 compounds will be completed at the
rate of one per month between January 1977, and June 1978. The
monographs will provide detailed tedhnical and safety information
which will assist the laboratory and field worker in implementing
the standards presented in this section.

-------

with the regulated chemical carcinogens. OperatIons involving
solid or liquid mixtures containing more than 1.0 by weight
or volume will be performed in a regulated area.
b. Medical Surveillance
(1) Preassignment Examinations — An appropriate preassigninent physical
examination shall be provided each person planning to work with
carcinogenic chemicals. The purpose of ‘this examination is to
establish a base level against which physiological changes
can be measured and to ‘determine whether there exists any
medical or’other conditions that may lead to increased risk
in the work situation.
(2) Periodic Examinations — All employees working with carcinogenic
chemicals shalibe provided periodic’ physical examinations.
The purpose of the periodic examination is to determine’ whether
a change has o.ccurred’ln the medical state or in other relevant
conditions which might lead to increased risk in the work

-------
40
situation. The examination shall be annual unless work
circumstances or the general health of the employee require
more frequent attention.
(3) Records — Medical’ records shall be maintained by the personnel
office for the duration of the employee’s assignment at NEIC.
Upon termination, transfer, retirement or death,, the medical
records or copies thereof, shall be transmitted to the
appropriate records holding facility where the.’ records will
be maintained for an extended period of time in a manner that
will insure ready access.
c. Personnel Practices
(1) , Laboratory Personnel
Protective clothing such as a fully fastened long—sleeved
laboratory coat shall be worn in any regulated area where
chemical carcinogens are being used. Gloves which are
appropriate to the specific situation shall be used when
handling chemical carcinogens. Clean protective clothing
shall be provided’daily and shall not be worn ‘outside the
regulated area once the regulated area has been ‘entered.
Clothing contaminated by éhernical carcinogens shall be
• decontaminated or disposed of immediately after an overt
exposure. Clothing contaminated with chemical cärcinogens
shall not be sent out for laundering until decontaminated.

-------
41
(2) Protective Equipment
Personnel engaged in procedures where exposure to airborne
particulates contaminated with chemical carcinogens could
occur shall wear an appropriate face mask and respirator.
The selection of an appropriate face mask and respirator
shall be made according to the guidance of the Safety Officer.
The face mask and respirator shall not be worn outside
the regulated area. Used filters shall be decontaminated or
disposed of daily. Safety glasses shall be worn during all
phases of carcinogen testing and cleanup of equipment. Contact
lenses shall not be worn while personnel are working in
a regulated area.
(3) Personal Hygiene
All personnel shall wash their hands immediately after
completion of any procedures in which chemical carcinogens
have been used. All personnel shall shower immediately
after any overt exposure to a chemical carcinogen.
d. Operating Practices
(1) Regulated Area Identification — Entrances to all regulated
and storage areas where chemical carcinogens are present
shall be posted with signs bearing the legend:
DANCER - - CH ICAL CARCINOGEN
Authorized Personnel Only

-------
42
(2) Access Control — Regulated and storage areas where chemical
carcinogens are present shall be entered only by personnel
authorized by the Laboratory Supervisor. Access procedures
shall be prominently displayed at points of access. Employees
entering regulated areas shall sign,a daily roster established
and maintained for that purpose. The rosters or a summary
of the rosters shall be retained for a period of 20 years.
(3) Work Surfaces — All work surfaces (bench tops, hood floors, etc.)
on which chemical carcinogens are used shall be covered with
stainless steel or plastic trays, uncracked glass plates,
dry absorbent plastic backed paper or other impervious
material. The protective surfaces shall be examined for
possible contamination immediately after the procedure involving
the chemical carcinogen has been completed. The contaminated.
surface shall be decontaminated or disposed of as is .appropriate.
(4) Use of Laboratory—Type Hoods — Procedures that involve the use
of chemical carcinogens shall be conducted in a laboratory—type
hood or other suitable containment device designed for. this
purpose when: (1) the procedure involves the use of volatile
chemical carcinogens, or (2) the procedure results in the
generation of aerosols such as from the opening of closed
vessels, transfer operations, and weighing. When flammable ‘
materials are used procedures shall be conducted in ‘an explosion—
proof hood. ‘ Each laboratory—type hood or containment device

-------
43
used for containment of chemical carcinogens shall display
a label bearing the legend:
DANGER -- ClIEMICAL CARCINOGEN
Laboratory—type hoods include both open—faced hoods and
laminar flow biological safety cabinets. An open—faced
hood is a device enclosed on three sides and the top and
bottom, which is designed and maintained so as to draw aft
inward at an average linear face velocity of 100 feet per
minute and a minimum air velocity of 85 feet per minute at
any point in the face of the fully opened hood and which is
designed, constructed and maintained, in such a way that
an operation involving a chemical carcinogen within the
hood does not require the insertion of any portion of
a worker’s body other than his hands and arms.
A laminar flow biological safety cabinet is a ventilated’•
containment device which provides both personnel protection
and a contamination—free work environment. Personnel protection
is provided by an inflow of room air at the work opening where
it. is quicklyentrained in a recirculating air stream and.
removed through an exhaust grill at the leading edge of
the work area. A contamination—free work zoneis provided
by supplying air through High Efficiency Particulate Air.
(HEPA) Filters downward towards the work surface at a
uniform velocity. Air flow equal to the inflow of room

-------
44
air is exhausted through HEPA filters incorporated in
the cabinet or the exhaust system.
Laminar flow biological safety èabinets may be used for
the containment of in vitro procedures involving use of
chemical carcinogens providing that (1) the exhaust air flow
is sufficient to provide an inward air flow at the face
opening of the cabinet equal to 100 feet per minute times
the face opening area, (2) contaminated air plenums that
are under positive air pressure are leak—tight, and -(3) the
cabinet exhaust air is discharged outdoors.
(5) Working Quantities — Only minimum working quantities of
chemical carcinogens shall be present in a regulated area.
(6) Identification, -Storage and Inventory
Labeling — Storage vessels containing chemical carcinogens
shall be labeled:
- DANGER -— CHEMICAL CARCINOGEN
Storage — Stock quantities of chemical carcinogens shall be
properly labeled, catalogued and stored in a specific storage
area that is properly vented and secured at all times.
Inventory - An inventory of all chemical carcinogens shall be
maintained by the Laboratory Supervisor. The inventory records
shall include the quantities of chemical-carcinogens acquired,
dates of acquisition and disposition. A copy of the inventory
records shall be furnished to the Safety Officer on a semi—annual
basis.

-------
45
(7) Laboratory Transport
Stock Quantities of Chemical Carcinogens — An unbreakable
outer container shall be used to transport chemical car-
cinogens. Materials contaminated with chemical carcinogens
which are transferred from regulated areas to disposal areas
shall be placed into separate plastic bags or other suitable
impeiineable containers, sealed and labeled with both the name
of the carcinogen and DANGER -- CHEMICAL CARCINOGEN before
being transported.
(8) Housekeeping — General housekeeping procedures which suppress
the formation of aerosols such as the use of a wet mop or a
vacuum cleaner equipped with a HERA filter* on the e haust
shall be used. Dry sweeping and dry mopping are prohibited
because of the hazard of aerosolformation. In those instances
where a chemical—containing material is spilled, special
procedures shall be followed.
(9) Protection of Vacuum Lines — Each vacuum service shall be
protected with a disposable HE R A filter and liquid trap to
prevent entry of any chemical carcinogen into the vacuum system.
When using a volatile carcinogen a separate vacuum pump or
other device shall be used in conjunction with an appropriate
laboratory—type hood or other containment device approved by
the Safety Officer.
* A High—Efficiency Particulate Air Filter which is capable of retaining
99.97% of a mono disperse aerosol of 0.3 pm particles.

-------
46
(10) Packaging and Shipping — The packaging and shipping methods
established by the Department of Health, Education and
Welfare for the transportation of etiologic agents (42 CFR
72.25, 1972) shall be applied to the shipment of all stable
chemical carcinogens. For chemical carcinogens which are
physically or chemically unstable (e.g., corrosive, explosive
or flammable) the procedures established by the Department
of Transportation for handling of such materials (49 CFR
173, 1973) shall be followed.
(11) Decontamination and Disposal
Contaminated materials including bacteriological culture
media shall be decontaminated by procedures.that either
inactivate the carcinogens or remove them for subsequent
disposal: Contaminated wastes and cleaning devices shall
be collected in impermeable containers which are closed prior
to removal from the regulated area and disposed o by
appropriate methods as approved by the Laboratory Supervisor.
• Chemical carcinogens which have spilled out of a primary container
so as to constitute a hazard shall be inactivated in situ or
shall be absorbed by appropriate means for subsequent disposal.
e Exhaust Air Treatment •
(1) Exhaust Air Treatment — The exhaust air from laboratory—type
• hoods and other ventilated containment devices shall be
appropriately treated such ashy filtration, reaction,

-------
47
absorption, adsorption, incineration or combination of
chemical carcinogens in the final effluent which is discharged
outdoors shall not exceed 1 pg/i or natural background
levels, whichever is greater. Removal of chemical carcinogens
from the exhaust air by collection mechanisms such as
filtration, absorption and adsorption shall be adcomplished
in a manner that permits maintenance while avoiding
direct contact with the collection medium.
(2) Performance Certification — Performance of laboratory—type
hoods and exhaust air treatment systems shall be checked
at least annually.
f. Facilities
(1) General Ventilation Control
General Exhaust Air — The general exhaust air from regulated
areas in which chemical carcinogens are used shall be
discharged outdoors and dispersed to the atmosphere so as
to prevent re—entry into the facility. No recirculation
of exhaust air from regulated areas is permitted.
Air Pressure — Regulated areas in which chemical carcinogens
are used shall be kept under negative air pres’àure with respect
to the access corridor. For facilities where regulated areas
have “clean” access corridors and “dirty” egress corridors,
the “dirty” egress corridor shall be kept under negative air
pressure with respect to the regulated area.

-------
48
D. WASTE DISPOSAL
Waste disposal is a part of the job that requires individual
thought, cooperation, and effort to get the task done safely.
Following is a brief’discussion of the types of waste and mode
of disposal. If in doubt, ask your superviáor or Branch Chief.
1. Waste paper is disposed of via waste baskets.
2. Broken glass, bottles, and non—toxic/non—flammable solids
are disposed of via the special containers present in each
laboratory area.
3. Water—soluble, non—hazardous materials should be flushed.
down the sewers via the drains.
4. Acids or corrosive materials can be flushed to the sewers
via the drains with a 50-to4 dilution with water.. special’
precautions must be taken with strong acids such as perchioric
acid.
5. Non—toxic, water miscible liquids such as, acetone and ethanol
can be flushed to the sewer via the drains with a 50-to—I.
dilution with water. Large quantities, of these materials
should be disposed of via the waste—solvent. drums described
• in the following paragraph.
6. Waste solvents (water—immiscible organic solvents) are disposed
of via the waste—solvent cans and waste—solvent drums. Waste—
solvent cans must be clearly marked safety cans. A waste—solvent
drum is located in the hazardous—materials storage area and must
be used for no other purpose.

-------
49
7. Any employee having a toxic waste for disposal must con-
sult with the appropriate supervisor or Branch Chief before
proceeding with a disposal procedure.
8, Pyrophoric materials or active metals will be handled in
the same manner as toxic wastes.
9. All toxic or obnoxious gases must be exhausted through hoods.
If possible, these should be destroyed, at the source, by
scrubbing, adsorption, reaction, or burning.
E. EMERGENcY PROCEDtJRES
Although most emergencies èanbe avoided by following the proper
measures in carrying out the usual type of work performed in the
laboratory, it is mandatory that laboratory personnel know what
steps and action to take in case an emergency occurs.
The laboratory Safety coordinator will periodically conduct a
safety refresher for all laboratory personnel. Attendance by
all employees, normalJ y engaged in laboratory work, is mandatory.
Emergencies most likely to occur in the laboratory and the steps
and actions to be followed in such emergencies are discussed herein.

-------
50
1. Fires
a. What to do in case Of fire:
Every employee must know the location of the fire
‘extinguishers and fire blankets. Each new worker
is to be given training in the use of all types
of fire extinguishers available in the laboratory.
lie or she must be familiar with the fire—alarm system.
The first person to see the fire should sound the alarm
immediately. Small fires can be extinguished with carbon
dioxide, dry powder, foam, or soda extinguishers. In
case of a large fire, the building should be evacuated.
Each employee should also know the location of. the safety.
shower and fire blanket tobe used inthe event their
clothing catches fire.
The following table classifies types of extinguishers
and the kinds of fires on which they should be used.
Class A Class B Class C Class C
Rags, Wood, Oils and Auto—oxidizing
and Paper Solvents Electrical Combustib les*
Carbon dioxide NO YES YES NO
Dry powder
agents YES YES YES NO
Foam YES YES NO NO
Water YES NO NO YES
Class A BC
Dry Chemicals YES YES YES NO
* Such as nitrocellulose.

-------
51
In general, dry chemical is preferred for solvent
fires and CO 2 is preferred for electrical fires.
Water is preferred for fires in which combustion is
supported by the oxygen contained in the material,
such as nitrocellulose. In this case, rapid cooling
of the material affords the best means of fire control.’
Foam is effective against liquid petroleum fires but
is usually not more effective than C0 2 , and the latter
eliminates the cleaning problem after use.
b. Solvent Fires
Solvent fires can usually be extinguished by the proper
use of dry chemical or carbon dioxide. Foam-type ex-
tinguishing agents are effective on some types of solvent
fires; however, their use is not recommended on high
vapor—pressure, chlorinated, or water—soluble solvents.
In many cases of fire in entail containers of solvents,
the fire can be snuffed out by placing the lid on the
container tightly enough to exclude air. If a lid is
not ‘available, a piece of sheet metal, asbestos board,
• or other similar non—combustible material will suffice.
c. Gas Fires
The surest and most effective means of extinguishing a

-------
52
gas fire Is by closing a valve in the gas supply line
thereby shutting off the fuel supply. however, gas
fires can be extinguished by. the properuse of carbon
dioxide or dry chemical extinguishers.
Serious consideration should ‘be given to allowing gas
fires to burn until ‘the source of gas can be stopped
to prevent possible explosionB.
d. Chemical Fires
Chemical fires can be of many different sorts, and
often special methods of fire fighting must be used.
For example, a sodium f ire should be smothered with
sand, never with water. All laboratory workers must
be taught the particular methods of handling these un-
usual kinds of fires. Often, if the fire is small and
does not endanger other combustibles, it is best to
let it burn itself out.
e. Electrical Fires
If possible, first turn off the power to the motor or
other electrical equipment. Use carbon dioxide or dry

-------
53
powder on electrical equipment, never water. Electrical
equipment involved in fire should not be placed in op-
eration until inspected and repaired.
Special’ procedures are necessary to accomplish emer-
gency shutdown of the gas chroinatograph—mass spectrometer.
These procedures are posted on the equipment.
2. Spills
a. Flammable Liquids
Leave the immediate vicinity as soon as possible.
Analyze the situation before attempting to take further
steps. If possible, shut off all sources of fuel and
remove potential sources of ignition by using outside
valves and switches, and circuit breakers. Electrical
hot plates and the open type of electric motors should
be turned off. If clothing is wet with flammable ma-
terials, consider the immediate use of a safety shower;
otherwise the clothing should be changed as soon as
possible, and the affected parts of the body washed
with soap and water,

-------
54
b. Strong Acids and Caustics
In the case of acid or caustic spiiis on •the body,
wash the affected portions with a large volune of water
then report to the nearest physician. Remove the
affected clothing immediately.
If these materials are spilled.on a ‘bench top or floor,
dilute them with a large volume of water and then
neutralize.
In case of a chemical burn of the eye, flush it with
clear water at the nearest eye bath and, then report
to the nearest physician.
c. Other Chemicals
Many hydrocarbons and chlorinated hydrocarbons give off’
toxic vapor8. In case any of thesematérials are
spilled, stay out of the vicinity until the fumes have
cleared’ away. If it is necessary to enter this vi-
cinity, the proper type of air mask must be worn.
Entry will be initiated only upon approval by the su—
pervisor or the Branch Chief. If toxic materials are

-------
55
apilled on the body, wash them off immediately with
soap and water, Laboratory employees should be
familiar with the gases that they are likely to
come in contact with and keep out of any area where
they have been released accidentally.
d. Contaminated Clothing
Clothing or shoes that have been contamInated with
corrosive or toxic materials, such as acidsor ban—
zene, should not be worn again until properly latin—
dared, steamed, or aired.
3. Rupture of Flammable Solvent Containers
In case of rupture of a flammable solvent container,
remove all sources of ignition, and remove the container
if possible, without hazard to a safe locatIon. Evacuate
the area immediately.
4. Failure of Laboratory Service Utilities
A variety of emergency conditions can arise because of
the failure of various service utilities such as steam,

-------
56
electricity, compressed air, etc. The Laboratory
Safety Coordinator will prepare and periodically update
a detailed list of things.to be done in any type of
utility failure. The list will be posted in each lab-
oratory module.
5. As hy ciat1on and Injury
a. •Each laboratory employee will render first aid to a fellow
employee who is asphyxiated, shocked, or injured to the
extent possible by the training provided.

ways. Such sampling points should be voidedwhèiie bssible;
4. Sampling from railroad bridges is not permitted, unless an
adequate walkway is present, or the railroad dispatcher has
been contacted, and it has been positively determined that Y
no trains will run during sampling period.
5. Vehicles will not be parked on bridgeS for the purpose of
sample collection.
6. All vehicles used for sampling and associated work will be
equippedwith amber rotary caution lights. Such lights are
to be operated during all operations wherein vehicles are
driven slowly on roadways or where parked near roadways..
7. All electrical apparatus employed in field operations must be
properly grounded.

-------

E. SAFETY PROCEDURES FOR FIELD ACTIVITIES INVOLVING’PESTICIDES AND
OTHER HIGHLY TOXIC MATERIALS
1. General
At all times, field personnel must take extreme precautions
to avoid contact with pesticides. Although ‘the’ toxicIty of
pesticides varies from compound to compound, all e.sticides
(insecticides, herbicides, desiccants, rodenticides, etc.)
must be considered extremely toxic. Pesticide poisoning may
be induced by inhalation, ingestion, contact.with mucous mem-
branes, or absorption through unbroken skin. The toxicity
of many other chemicals, not classified as pesticides, is
high; safety precautions to prevent exposure to these
chemicals are identical to those used for pesticides. If
there is doubt concerning the toxicity or concentration of
a pesticide or other toxic chemical, the employee will
act conservatively in favor of safety.
2.: Sampling of Pesticide Formulations and Mixtures
Sampling of pesticide formualtions and mixtures requires
extreme caution because pesticide concentraitons are high
and chances of exposure from spillage or by other means are
great. Care must be taken to insure that there is no
skin contact with sampling devices or other contaminated,
surfaces during or after sampling. -Pesticide samples will
be removed from their containers through plastic tubing.

-------
75
Suction will be applied to the tubing by collapsing, then
releasing a plastic bottle attached to the tubing;
suction by mouth is not permitted. Samplebottles
containing pesticides or other highly toxic chemicals
shall be clearly marked with individual labels identifying
hazardous contents.
3. Decontamination and Disposal of Sampling Equipment
On completion of sampling, the plastic tubing will be cut
into small pieces and the plastic bottle will be cut
into two pieces. Sampling devices will be placed in a
plastic bag and disposed of by appropriate methods as
approved by the Laboratory or Field Supervisor. The
knife or scissors used to destroy the tubing and plastic
bottle will be washed after use.
4. Protective Clothing for Formulation and Mixture Sampling
Protective Clothing, to be worn during all phases of !ormulation
and mixture sampling or observation, consists of the
following:
A. Head Cover
B. Face Shield or Goggles
C. Respirator
B. Long—sleeved Coveralls
E. Waterproof Apron
F. Heavy Rubber Gloves
G. Rubber Boots

-------
Whenever there is the possibility that the employee may
be sprayed by a pesticide, such as during close observation
of applications, the following items of protective clothing
will be worn:
A. Head Cover
B. Face Shield or Goggles
C. Respirator
D. Long-sleeved Coveralls
E. Hand Covers
F. Rubber Boots
Unless. another entry time is specified on the pesticide
label, protective clothing to be worn when entering a field
within 48 hours after pesticide application will be:
A. Head Cover
B. Respirator
C. Long—sleeved Coveralls
D. Hand Covers
E. Rubber Boots
Long—sleeved coveralls and hand covers must be worn when
handling objects that may have contacted pesticide spray
or drift.
5. Decontamination and Disposal of Protective Clothing
After use of protective clothing to prevent pesticide contact,
head coverings, coveralls, aprons and gloves should be
folded or turned inside—out, then placed in a plastic
bag, and sealed. Subsequently, these items’ shall be
disposed of or washed. Face Shields, goggles, respirators,
rubber gloves and boots should be washed between uses.

-------
77
Protective clothing upon which pesticides have been
spilled or splashed should be removed (taking care to
avoid skin contact), placed in a plastic bag, and disposed
of by appropriate methods as approved by the Laboratory
or Field Supervisor.
F. SAFETY PROCEDURES FOR AIR POLLUTION SOURCE TESTING
1. Personnel will strictly adhere to all Company safety rules
applicable to the source being sampled. They shall familiarize
themselves with all warning signals in use at the facility and
procedures to follow when these signals are sounded.
2. All ladders, scaffolds, platforms and railings will conform
to O.S.H.A. regulations.
3. O.S.H.A. approved ladder fall devices will be worn by
personnel using uncaged ladders more than 20 feet high and/or
not provided with rest platforms at minimum 2D—foot.intervals.
4. Safety lines will be worn on all work platforms more than
six feet above ground level during high wind conditions, when
work platofrms are slick, or when safety rails are not
available.
5. Asbestos gloves will be worn when handling hot objects.
6. All electrical equipment will be suitably grounded.
7. Where the potential exists for the presence of toxic
gases, detection tests shall be run prior to source testing
personnel entering the area.

-------
78
8. Protective gear such as respirator, goggles, safety
glasses, safety shoes, ear plugs and hard hats will at
all times be in the possession of persons conducting source
tests and will be worn when appropriate. Protective
masks or goggles and respirators will be worn when in the
vicinity of toxic gases.

-------
79
G.’ SAFETY PROCEDURES FOR UNDERWATER DIVING OPERATIONS
1. General
Safetywill be the prime consideration in conducting under—
water pollution control activities. All underwater
activities must be approved in advance by the Center Director
or his designee. NEIC employees may participate only if
they are in good physical condition, have successfully
completed the necessary training, and are properly equipped.
2. Individual Diver Responsibilities
a. Each NEIC diver is responsible for maintaining good
physical condition and a high level of diving proficiency.
b. Each diver must conduct diving activities in the safest
manner possible.
c. Each diver is expected to exercise good judgement and
refuse to dive if conditions are unfavorable or
unsafe. A diver who does not feel in proper physical
or mental condition or who in diving would violate these
regulations or the dictates of diver training must not:
dive.
d. Each diver must maintain an up—to—date log of all diving
activities and have it available to the Center Diving ‘.
Officer after each diving activity.
3. Certification.
a. Center Diving Officer — The ‘Center Diving ‘Officer shall’

-------
80
establish the criteria for evaluating qualifications
and shall issue certifications for diver trainee,
divers and diving supervisors authorizing the diver
to engage in the types of diving operations for which he
is qualified. The Diving Officer is responsible for
the implementation of Agency diving safety policies,
review of operating procedures, investigation and reporting
of any diving accidents, and recommendation of any needed
changes. In addition, the Diving Officer conducts
certification and refresher training programs and
maintains an up—to—date file on each diver, including
certification, diving logs, physical examinations
and training completed.
b. Basic Training — Each NEIC diver must successfully
complete a basic SCUBA training course approved by
the Center Diving Officer.
c. Medical Examination — Each diver must pass a medical
examination by a licensed physician who will attest
to the applicant’s physical fitness for diving.
d. Diver Trainee — A diver •trainee is eligible to partici-
pate only in closely supervised dives under conditions
of limited hazards.
e. Diver — A diver becomes fully certified and eligible
to engage in all NEIC diving activities after logging

-------
81
at least 50 dives, three of which must have been with
the Center Diving Officer.
f. Divii g Supervisor — A diving supervisor must have
logged at least 100 dives, three of which must have been
with the Center Diving Officer. In addition, a diving
supervisor must have completed an advanced diving
•training course approved by the Center Diving Officer.
A diving supervisor performs as the diving leader
responsible for preparation of the dive plan and coordin—
at ion of divers, at the dive site.
g. Certification Maintenance Certification will remain in
effect provided that divers successfully complete a
thorough annual physical examination and log an
average of two dives per month during the year. If
more than six weeks elapse without a dive,, the diver must
complete a “check out” specified by the. Center Diving
Officer before. resuming work dives. Certification
may be revoked by the Center Diving Officer with concurrence
of th Director for violation of the safety regulations or
for any act endangering the diver or other diving personnel.
4. Diving Operations
a. All scuba and other diving equipment and air compressors
will be checked, maintained and operated in accordance
with appropriate provisions of the ’U, S. Navy Diving Manual,

-------
82
NAVSHIPS 250—538, and the equipment manufacturer’s
instructions. A carbon monoxide test will be made
during each air tank filling operation if an internal
combustion engine—powered compressor is used. The
carbon monoxide test may be waived if the following
conditions exist: (1) the inlet air duct is
25 feet away from an internal combusiton engine, and
(2) the exhaust is downwind and higher in elevation
than the intake.
b. Before any diving operation is undertaken, environ-
mental conditions should be observed for possible
danger to divers. Examples are: factory drain
pipes, cross—currents, tide conditions, and weather
changes.
c. Before any diving operation is undertaken in waters
exceeding 33 feet in depth, the diving supervisor
shall ascertain the location of the nearest qualified
medical and decompression chamber facility and the most.
expeditious means of summoning emergency assistance,
including U.S. Coast Guard or air transportation. All
participants in the diving operation shall be provided
with this information.
d. A detailed plan of the diving operation shall be
submitted by the diving supervisor to the Center Diving
Officer before the operation is conducted.

-------
83
e. The diving depths and the times should be limited
so that decompression staging will not be required
except as maybe necessary fOr emergency rescue,
in which case the U. S. Navy Standard Air Decompression
Tables will be adhered to. Decompression tables
should not be copied, except by photographic methods
which reproduce an exact copy. The maximum depth
for dives shall be 130 feet.
f. Divers are required to wear a knife, wrist watch,
compass, and depth—indicating device. An inflatable
life jacket, equipped with a CO 2 filler or capable of
being inflated from the diver’s air supply, shall be
worn except when using an inflatable or pressurized
diving suit. The wrist watch, •depth—indieating device,
and compass may be omitted in waters. not exceeding
15 feet in depth, if in the opinion of the diving super-
visor they will not contribute to the safety of the
operation. All harness and weight belts must have a
quick release, operable by a single motion of either
hand.
g. No one will be permitted to dive alone or unattended
except as maybe required for emergency rescue. Divers
will conduct operations in pairs working as a unit under
a buddy system with each diver responsible for the:

-------
84
other’ssafety. When underwater visibility is good,
each shall keep the other continuously in sight. When
visibility is poor, divers will maintain contact with
one another by touch (side—by—side). If contact is
lost, both divers will return immediately to the
surface.
•A diver locator device such as a sonar—pinger should
be worn by divers when diving in poor visibility water
when the potential exists of a diver being trapped by
bottom material or when strong currents are present.
h. A surface tender will be provided for each working unit
or buddy pair. It is the surface tender’s job to
be ready to provide emergency assistance. The surface
tender must be a qualified diver equipped and prepared
to render immediate emergency assistance. The surface
tender may operate on shore or from the deck or a boat
as may be appropriate, but in most cases should not be
more than 50 feet from the immediate diving area. When
operations are conducted from a boat, there shall be a boat
operator in addition to the surface tender. The surface
tender must always be aware of the diver’s location.
1. Underwater time must be monitored closely, either by.
the surface tender or diving supervisor, to guard against
fatigue and over—exposure.

-------
85
j. A diving flag must be flown while diving in areas
where other boats could present hazards.
k. All regulators shall be equipped with an additional
second stage and pressure guage, and will be inspected
by a certified regulator mechanic at least once per
year.
1. Each dive team must have at least one NEIC certified
diving supervisor.
in. Each dive will be planned in advance. The diving
supervisor will place one of the divers in charge
of the dive. Any divergence from the dive plan during
a dive must be agreed upon by all divers. There will
be no independent action of any diver during a dive
(except in an emergency).
n. Oxygen shall be available at each dive site for
immediate treatment of decompression sickness.
o. All divers will avoid flying for 12hours after diving,
unless being transported to emergency treatment.
p. All divers will be qualified to administer emergency
medical treatment, including cardiop ilmonary
resuscitation.

25 percent efficient, much of the energy
in what we eat results in the production
of body heat which is
transferred, and lost, to
the environment.
The physiological pro-
cess of maintaining body
temperature may be
compared to an equation
of. equilibrium, or a
teeter-totter. One side of
the equation, or teeter-
totter, is concerned with —-
heat production. The
opposite, balancing side is
concerned with heat con- 20
servalion. Our understand-
ing of this principal of
what we can do to
maintain our body’s
thermal-equilibrium will
give us the knowledge
essential to prepare for
and survive winter’s cold. -
Our body produces
heat by two methods. Ore
is through the absorption
energy from the sun or other heat
sources. Therefore, if we are the victims
of an emergency landing in the winter, we
should stay within the sun’s rays and, if
at all possible, build a fire.
The other and most important method
of producing heat is through the body’s
metabolism. Our metabolic rate (rate of
food conversion into heat) can be
increased both by what we eat and by
physical exercise. Therefore, we should
first pay pirticular attention to our
wintertime diet. Our meals
should consist of highly
nutritional food and be
well-balanced in order to
provide our digestive
systems with a regular
source of energy that will
in turn be used to
maintain our body’s heat
supply. Then, we can, for
brief periods, increase our
metabolic rate by eating
something with a large
sugar content, such as
candy. Do not replace a
normal food intake with
candy, however, because
sugar can over-tax the
pancreas. But, used
judiciously, candy can
help us keep warm in an
emergency and should be
added to our aircraft’s
survival kit as a wintertime
supplement -
Any type of physical exercise will
increase our metabolic rate. Beyond the
essential activities such as preparing
rescue signals or building fires, we
shouldn’t waste our time and valuable

total heat loss, but the amount of
moisture lost from our body in this way
is very important to the prevention of
dehydration. Therefore, even in the
winter, our survival kits must contain
water purification tablets.
Use, the geographical area
in which you fly to
estimate your rescue time,
and carry enough tablets
to provide each passenger
with a minimum water
supply of two quarts per
day. -
Sensible perspiration is
the process of losing
moisture through the
sweat g!ands. If the
temperature is cold
enough for us to be con-
cerned wit i keeping warm,
then there shouldn’t be
-any reasoi for sweating. In
fact, excessive sweating in
cold weather is very
dangerous Our bodies not
only lose the heat in
evaporating the sweat, but
the resulting vapor
seriously reduces the insulating properties
of our clothing.
Body heat lost by radiation is signifi-
cant only when we are scantily dressed.
So, this method of heat loss is minimized
by any amount of winter dress. As a
result, radiation losses are almost
insignificant in the winter.
Heat is lost by conduction whenever
any part of the body comes into contact
with something cold. Therefore, our feet
are normally the first parts of our body
to get cold because they usually are in
contact with the ground.
So, if we sit, lie down, or
touch anything cold, our
conductive losses increase
• markedly. Normally,
however, the body’s con-
ductive loss is minor and
can be minimized by
avoiding direct contact
with cold objects. When
we must sit or lie down,
we should place some kind
of insulating material, such
as a blanket, between our
bodies andthe ground.
Convective heat loss
can be quite severe and is
the single most important
survival problen’i. It
depends not only upon the.
temperature, but also
upon the relative move-
ment of air around our
body. For these reasons,
the Army assigned Major
Paul A. Siple to conduct extensive
research into the cooling-power effect of
temperature and wind combinations. His
research dates back to 1939 and resulted
in the origination of the term “wind-chill.”

The body loses heat by five major
methods: insensible perspiration, sensible

Insensible perspiration is the continual

For a period of time, wind-chill was
expressed simply as the numerical pro-
duct of temperature and wind speed.
Later, during World War II. Major Siple
conducted further research into the
wind-chill effect and
formulated a more
accurate index. His index,
which is used today, is 2
expressed by a formula
based upon the freezing
rate of water. Major Siple
developed the formula
empirically from volumi-
nous experimental data
and took into account
such factors as surface
area, time, temperature 2
and wind speed.
We should always seek
shelter from the wind, but
the most important way of
minimizing our bodies’
convective heat loss is
through the proper use of
clothing. This presents a
pilot and his passengers _______
with both a unique and a
difficult problem.
If we were going hunt-
ing, we wou.d dress S
properly for the continual
exposure to the outside
weather. When flying, 8
however, such dress would
be far too warm for an .2
airplane’s heated cabin.
The answer to this prob-
lem is a compromise: dress
moderately warm and
carry additional clothing
in the survival kit.
As far as clothing
materials are concerned,
air is the best insulator.
Thus winter clothing
should consist if several
loose layers which will ____________
entrap air between them
and provide the hest possi ’ 4
ble insulation. Wool is the
next best insulator. Also,
unlike other clothing
materials, wool retains g
most of its insulating
properties when wet. g
To take maximum 2
advantage of both these
materials, underwear
should be made of loosely 0
woven wool (although
cotton will •do if wool is
unavailable or you have an
allergy problem). This gar- —
ment can be of the one or
two-piece variety and, like
all of our winter clothes,
must fit comfortably loose to preven i any
restriction of blood circulation. Very
light cuffing around the wrists, neck and
ankles will maximize heat retention by
preventing cold air from getting inside.
The second layer of clothing should be
made of a medium-weave, medium-weight
material. Wool also would be good here,
but to prevent getting too warm, cotton
or some similar material will do.

GERRY Diyis on of Outdoor Sports Industries, Inc.
The outer layer of clothing should be
a one-piece garment, like a flight suit, and
be made from a tight weave, wind
resistant material such as nylon.
In addition to this clothing, the winter
supplements in our survival kit must
include gloves, hats and warm jackets
with insulated hoods for each person.
All of these garments must be kept
clean and in good repair because insulat-
ing properties are greatly
reduced if clothing is dirty
or torn.
Notice that none of
these garments is made
from wind or waterproof
material. The reason is
that clothing must be
allowed to breathe. That
is, there must be a small
amount of air circulation
between and through the
clothing layers. Otherwise,
perspiration would be
trapped within the cloth-
— ing and greatly reduce its
insulating properties. This
brings up another closely
related problem, getting
wet.
Getting wet presents a
___________ problem similar to that of
excessive sweating, but it
is far more serious.
Because water conducts
heat very quickly, getting
wet virtually destroys all
of clothing’s insulating
value. Body heat is then
immediately conducted to
the outside cold air. If one
becomes totally immersed
in cold water, death can
occur within just a few
minutes.
In the 70- to 80-degree
temperature range, our
bodies are in thermal
ec’iilibrium. That is, heat
__________ production equals heat
loss and the thermal
teeter-totter is in balance.
____________ Below this temperature
range, heat losses exceed
heat production, thermal
equilibrium is lost and we
start feeling uncomfort-
able. Left improperly
clothed, our bodies resort
to one or more of the
following physiological
methods of producing and
conserving in ore heat:
1. Goose pimples—This
erects body hair which in
turn increases the
thickness of the thin
insulating . air blanket
entrapped within our body
hair.
2. Shivering—These
involuntary muscle exten-
sions and contractions increase our
metabolic rate to produce additional
heat.
3. Reduced skin temperature—This is
accomplished by a slight decrease in the

yellow-white spot on the skin, before you
can feel the pain.
The affected area must be warmed
quickly. Frozen parts should be thawed
in water until soft, even though the
treatment is painful. This treatment is
most effective when the water tempera-
ture is exactly 107 degrees, but water
either colder or hotter may be used. If
warm water is not available, wrap the
frozen part in blankets or clothing and
apply improvised heat packs. Body heat
The best drink to carey with you on a
winter flight is hot chocolate. Hot
chocolate is both warm and nutritiorta [ —
coffee is only a warm drink and a
temporary stimulant. One important
thing to remember with regard to eating
and drinking, however, is don’t eat unless
you have enough water to drink. Eating
increases thirst. Your will to survive is of
paramount importance and with it you
can survive several days without eating as
long as you have water.
An excellent source of information on
building shelters and campfires is U.S. Air

blood flow to the skin. The result is a
smaller temperature differential between
our skin and the surrounding cold air, so
less heat is lost.
4, Vaso-constriction--This is an
involuntary and sometimes irreversible
body process whereby the blood flow to
our extremities is decreased significantly
or stopped entirely. The one exception is
the blood flow to the head. Because life is
dependent upon the brain’s proper func-
tioning, the head’s blood supply is never
reduced by vaso-constriction.
These physiological activities also
serve another important function. They
can be used as warning signals of impend-
ing danger. Goose pimples and shivering
usually are the first and most obvious
signals; they make us feel uncomfortable.
But, reduced skin temperature and vaso-
constriction are much more subtle. They
can begin slowly with a gradual feeling of
numbness. However, total loss of feeling
follows quickly. If these signals are left
unheeded, you can be seriously injured or
even die.
Frostbite is the most common type of
cold injury and, regardless of the wind-
chill index, can only occur when the
temperature is below freezing. You can
see the effects of frostbite, a grayish or
also can aid thawing. Hold a bare, warm
palm against frostbitten ears or parts of
the face. Frostbitten hands can be held
against the chest, under the armpits or
between the legs at the groin.
Never rub a frostbitten area. You may
tear frozen tissues and cause further
tissue damage. Never apply snow or ice
because it increases the cold injury. Do
not try to thaw a frozen part by
exercising. Exercising of frozen parts will
only increase tissue damage and is likely
to break the skin.
Hypothermia, lowering of the body’s
temperature, results from total water
immersion or exposure to extreme cold.
Symptoms such as shivering, drowsiness,
lack of muscular coordination, disinterest
in food or water, and total loss of the
sense of touch and the sense of pain may
be experienced, If hypothermia
continues, the body’s temperature will
drop to 95 degrees with loss of all
thermal control. A coma results and
death finally occurs when the body’s
temperature lowers to 79 degrees.
When any of these symptoms are
experienced, the body must be given
additional heat immediately. Warm
liquids, food, additional clothing or
blankets, and a fire will prevent death.
Government Printing Office, Washington,
D.C. 20402). This manual is the best
single source of survival information and
is a must for your survival kit.
S aintaining a proper heat balance can
be q’lite a problem. Obviously, when you
are wearing enough clothing to keep
younelf warm at.rest while awaiting
rescue, you will be too warm when
exercising. Use your head.
That is, use your head as a heat
radietor. Remember, your head’s blood
circulation is never reduced by vaso-
constriction. Therefore, when you must
exer’ise vigorously, remove or vary the
amount of insulation around your head.
Then your circulating blood will transfer
the excess body heat to your head where
it can be radiated in place of creating an
excessive amount of sweat.
If your hands or feet get too cold, and
you’re already wearing a hat, pull your
jacket’s insulated hood over your head.
This will cause vaso-dilation of the
circulatory system to your extremities.
Being unable to radiate heat from your
head, your blood will then transfer the
heat to your hands and feet.
Remember, winter’s cold can be
survived, but survival is a matter of being
forewarmed.

in hazardous quantities only if the metal is in finely divided form.

amounts of heat , or generate
ressures from the large
volumes of gases produced.
knhydrides react to form the cor-
responding acids and can cause
vigorous boiling of the mixtures
if sufficient cooling is not
applied. Alkali metals react
vigorously with water to form
hydrogen gas and hydroxides;
cause heat-producing boiling
of mixtures. Metals and oxides
react similarly with alcohols,

or react spontaneously. Phosphine, phosphorus, metallic
with air sodium and potassium, and
products of similar properties
will ignite spontaneously in
the presence of air without
a source of ignition. They
should be handled and stored
with air excluded. For example,
store the alkali metals in
kerosene.
Sodium sorbate, linseed oil,
hex tldehydè, butyraldehyde,
and products of similar prop-
erties will oxidize on contact
with air under proper conditions.
Care should be exercised to avoid
spilling on contact insulation
around steam lines. Do not use
rags to them . On oxida-
tion, these materials release
heat that, in turn, raises the
temperature of the rag material
to its fire point.
B. A ha2ardcus chemical is one that does not qualify as a
reactive chemical but which is hazardous from the stand-
point of Health , Fire, or Reactivi y with other chemicals.
Some chemicals, reactive in the usual sense of the word,
do not fall within the strict definition of a Reactive
chemical. For example, neither ethylene nor chlorine
reacts with itself under usual conditions. Each is a.
hazardoua chemical. The two react together vigorously
to form ethylene dichioride, a reaction that could get
out of control.

C. The following system can be used to indicate the degree
of Health, Fire, and Reactivity of chemicals:
Health Hazards Rating Fire Hazard Rating Reactivity Rat
1. No residual injury 0. Non—flammable 1. Normally stable
expected
2. Minor residual injury 1. Flash point above 2. Reactive with
possible 60°C (140°F) water
3. Major residual injury 2. Flash point from 3. Self—reactive
if not treated 38—60°C (100 to with contaminants;
140°F) temperature sensitive.
4. Major residual injury; 3. Flash point from 4. Self—reactive with
prompt treatment 23—38°C contaminants; temper—
required. (73 to 100°F) ature and shock sen—

These classifications are based on physical and chemical
properties and do not include conditions of exposure or
handling such as pressure, weight, velocity, or volume.
Signals should be revised by the user to represent the
hazard under conditions of actual use.

icàls that are rated numerically for their Health, Fire,
and Reactivity Hazards, as classified by these tables.

E. Because of the wide range: of hazards involved it is not
practical to list all the necessary precautions in this
• manual. However, it is felt that some discussion of the
hazards and precautions is necessary, at least to the
• extent of citing, examples. •

-------
C -4
Toxicity and Health Hazards —— The newer chemicals are toxic
in varying degrees and much in the same manner as the older)
veil-known chemicals; by inhalation, ingestion, absorption
and contact.
The toxicity resulting from the Inhalation
of the chlorinated ‘hydrocarbons has already
been mentioned. In other chlorinated corn—
pound8, absorption through the skin, in
addition to inhalation, can be a problem.
In fact, any heavily chlorinated compound.
in liquid or solution form or any used at
elevated temperatures should be handled
cautiously.
The isocyanates, exemplified by toluene
diisocyanate (TDI), are among the most
toxic, from repeated contacts, of the
modern industrial organic chemicals.
Isocyanates, particularly those in liquid
form and those used at elevated temper-
atures, should be handled with suitable
precautions.
While it has been known far many years,
epichiorohydrinis an organic chemical
finding increasing use in the rubber and
plastics industry. This compound and some
of its derivatives are toxic in much the
same manner as are the isocyanates and should’
be treated similarly. Furthermore, epichioro—
hydrin slowly penetrates rubber so that rubber
clothing that has been in contact with the
liquid should be discarded.
The aminee, particularly the liquid ones and’
those used in solution form, frequently cause
problems with dermatitis, throat irritations,
conjunctivitis, etc., unless handled with
suitable protective equipment.
Fire and Explosion Hazards —— Many modern industrial chemicals
are extremely fire and explosion hazardous. The hazards arise
from many causes, some of which are: Loss of inhibitor, expo-
sure to oxygen (air), shock, sensitivity, friction, thermal
changes, contamination by metals and their salts or oxides, etc.
Some specific examples are given.

-------
C-5
• Equipment should be well designed and suitable
for the type of reactions involved with peroxides.
The peroxid to be used should be carefully
selected. Whenever possible, particularly if
there is a choice, the less hazardous one
should be chosen. Dilution with a compatible
material is advisable whenever possible.
Only the quantities immediately needed’should
be stored in the laboratory. All storage and
handling should preclude the possibility of
contamination of. the peroxide or the contami-
nation of other materials by the peroxide.
It is suggested that the weight of actual
peroxide in storage be limited as follows:
Peroxide. Cutoff Area Detached Area Laboratories 2
Hazard Unopened Unopened per 5,000 ft
Classification containers Containers floor space
20 lb 1,000 lb . 2 lb
II 100 lb 5,000 lb 10 lb
III 500 lb 25,000 lb 50 lb
Many purified chemicals are susceptible to
oxidation and rapidly form potentially
explosive peroxides after the container
has been opened and the substance exposed
to air. A typical example is purified
tetrohydrofuran (T1iF). . Precautions include:
use of inhibited materials whenever possible;
buying in minimum practical—sized containers
and immediately discarding any unused remainder
in a container; :
dating containers with the date received,
followed by a strict rotation of stock; dating
the containers with the date opened and dis-
carding if not used within a prescribed time
limit;. . •
the addition of suitable inhibitors that will
not interfere withe the intended use of the
remainder.

-------
C -6
Hydrazine is a dangerously reactive chemical
that, with some of its derivatives, is
finding increasing use in syntheses in the
chemical and plastics industries. It isa
highly active reducing agent and reacts with
many organic and inorganic chemicals.
Anhydrous hydrazine and unsymmetrical diinethyl
hydrazine are such unstable compounds that
they were earlier used as monopropellants and
are considered as explosive substances. Other
derivatives are considered flammable liquids
having very low ignition temperatures and high
chemical reactivity.
Decomposition can be initiated by heat,
electrical sparks and arcs, by the catalytic
action of oxygen, and by contaminants such
as the oxides of heavy metals. -
The usual properties relating to flammable
liquids are not always fully indicative of
the major hazards involved although some of
these properties confirm the unstable nature
of hydrazine. As an example, anhydrous
hydrazine has a reported upper explosive
limit (U.E.L.) of 100 percent vapor, by
volume, which indicates that oxygen (air)
is not necessary to produce an explosive
type reaction. Such explosions can be initia’-
ted in closed containers, pipes, etc., by out-
side sources of heat, by internal catalytic
influences, and by. reaction with contaminants.
The precautions for these compounds follow
closely those required by the organic peroxides:
limitations on quantities, rigid standards on
shelf—life, disposal of residues, protectIon
from heat, isolation to prevent contamination,
strict control of ignition sources, and others.

TEN SAFETY RULES FOR SURVIVAL IN THE DESERT
1. Never go into the desert without first informing someone as to
your destination, your route arid when you will return. STICK
TO YOUR PLAN.
2. Carry at least one gallon of water per person per day of your
trip. (Plastic gallon jugs are handy and portable.)
3. Be sure your vehicle is in good condition with good hoses,
spare tire, spare fan belts, necessary tools, and reserve gasoline
and oil.
4. KEEP AN EYE ON THE SKY. Flash floods may occur any
time “thunderheads” are in sight, even though it may not rain
where you are.
5. If your vehicle breaks down, stay near it. Your emergency
supplies are here. Raise hood arid trunk lid to denote “Help
Needed.”
6. If you are POSITIVE of the route to help, arid must leave your
vehicle, leave a note for rescuers as to when you left and the
direction you are taking.
7. If you have water—DRINK IT. Do riot ration it.
8. lf water is limited—KEEP YOUR MOUTH SHUT. Do not talk,
do not eat, do not smoke, do not drink alcohol, do riot take salt.
9. Do not sit or lie DIRECTLY on the ground. It may be 30.
degrees or more hotter than the air.
10. A roadway is a sign of civilization. IF YOU FIND A ROAD,
STAY ON IT. (Other people use it, too.)
A WORD OF CAUTION: The desert is beautiful and deadly. Danger is
always present once you leave well-traveled roads. Not only strangers
andSunday sightseers have found this to be true. Many native-born
Arizonans have been careless and suffered the consequences. The
information in this manual may save your life.
ANOTHER WORD: In case of a nuclear disaster do not attempt to avoid
radioactive fallout by evacuation to the desert unless you have a fallout
shelter at your destination. Radioactive Fallout will be in the form of
frne sand or dust, and its area of descent cannot be predetermined.
RADIATION cannot be seen, tasted or felt. Its presence can be deter-
mined only by special instruments. Learn about your Community
Shelter Program 4 and how to take advantage of your immediate sur-
roundings if a community shelter is not available.
GENERAL
The Desert Southwest is characterized generally by brilliant
sunshine, a wide temperature range, sparse vegetation, a scarcity
of water, a high rate of evaporation and low annual rainfall. Some
areas are flat and sandy, some mountainous and rocky, and others
may be salt marsh or dunes. As opposed to the normally thought
of summer conditions of extreme heat and severely parched char-
acter, the balance of the year affords usually moderate tempera-
tures, and especially in the spring, a surprising amount of life and
color. The desert supports a large variety of animal and plant life,
although for the most part it is diminutive in size or modified due
to its adaptation to the environment.
TRAVEL
Travel in the desert can be an interesting and enjoyable
experience or it can be a fatal or near fatal nightmare. The con-
tents of this small manual can give only a few of the many details
necessary for full enjoyment of our desert out-of-doors. Much
more must be learned of the basic principles of outdoorsmanship
and self-reliance, and there are many sources waiting to be
tapped for their information, The Boy Scouts of America, The Girl
Scouts, Camp Fire Girls, The American Red Cross, The Na-
tional Rifle Association, The National Field Archery Association,
The Arizona Game and Fish Department, The Phoenix Desert
Botanical Gardens, and many more, offer information or services
which will be useful to you. Unlimited satisfaction awaits the
person who is willing to take advantageof the desert and who
prepares himself for this unusual environment.
ALWAYS BEFORE GOING INTO THE DESERT, INFORM
A RELATIVE OR NEIGHBOR EXACTLY WHERE YOU ARE
GOING AND WHEN YOU WILL RETURN.
Pathfinding: When you plan on going into strange country
obtain a map beforehand and study the terrain features, the road
structure (do the roads run mainly north and south, or east and
west?), the directions to the nearest habitation, location of water,
etc. When you arrive at your campsite, recheck your map, look
for landmarks and orient yourself with the prominent ones. As
youmove through the country check your back trail often, mak-
ing mental pictures of the land behind you — this is what you will
be looking for when you return to camp. Take into consideration
the position of the sun and shadows, and where they will be at
the time you expect to return. Stay on established trails, if pos-
sible, or mark your route by blazes or other marks. Make a blaze
by a single downward chop with a hatchet or heavy knife on a
thin-barked tree or by one downward and one upward stroke on
a thick-barked tree to expose the light wood. Make bush marks
by breaking over the top leaving it attached by the bark. Make
1

-------
other marks by aligning •stones to form arrow shapes, or by
slanting sticks into the ground in the direction that you are
going. Travel from one prominent point to the next, making a
direction mark at every stop.
If you think you are lost do not panic. Sit down for awhile,
survey the area and take stock of the situation. Try to remember
how long it has been since you knew where you were. Decide on
a course of action. It may be best to stay right where you are and
let your companions or rescuers look for you. This is especially
true if there is water and fuel nearby, or in winter, if there is
some means of shelter. Once you decide to remain do not move.
Make a fire — a smoky one for daytime and a bright one for the
night. Other signals may be used, but fire is by far the best.
If you feel, after thinking the situation over, that you can re-
trace your course, do so. Mark your spot or leave a note before
moving on. Look for tracks, you may be able to back-track and
find your way to familiar ground. Do not try to take shortcuts
as this may tend to further confuse you. If possible, climb a tree
or a high point and make a sketch of the area before moving.
Always move, down stream or down country, but travel the ridges
instead of the washes or valleys. Make marks as you go. Travel
by landmarks or compass and do not try to move too fast.
REMEMBER, MOVE WITH A PURPOSE, NEVER START
OUT AND WANDER AIMLESSLY.
Walking: There are special rules and techniques for walking
in the desert. By walking slowly and resting about 10 minutes
per hour a man in good physical condition can cover at the out-
set about 12-18 miles per day — less after he becomes fatigued
or lacks sufficient water or food. Consider walking at night. It
is cooler and if lack of water is a problem you will dehydrate less.
You can navigate by the stars. The disadvantages are that you
cannot see well and may stumble, or you might overlook water
and food sources and indications of habitation. On the hot desert
it is best to travel early morning or late evening, spending mid-
day in whatever shade may be available. The position of the sun
early and late in the day will give a better sense of direction. In
walking, pick the easiest and safest way. Go around obstacles, not
over them. Instead of going up or down steep slopes, zigzag to
prevent undue exertion. Go around gullies and canyons instead of
through them. Use a steady easy step. When going down hill, bend
the knees considerably. When climbing, place the whole foot on
the ground at one time, not the heel alone. When walking in sand,
lean well forward, keeping the knees bent. On walks of long dura-
tion do not swing the arms, but grasp the shoulder straps of your
pack or the shirt at the shoulder seams to prevent the hands and
lower arms ftom swelling, and creating undue fatigue. When
walking with companions, adjust the rate to the slowest man.
Keep together but allow about 10 feet between members.
At rest stops, if you can sit down in the shade and prop your
feet up high, remove your shoes and change socks, or straighten
out the ones you are wearing. If the ground is too hot to sit on,
no shade is available, and you cannot raise your feet, do not re-
move your shoes as you may not be able to get them back onto
swollen feet. However, unlace boots, adjust socks and relace.
Automobile Driving: Cross country driving or driving on
little used trail roads is hazardous, but can be done successfully
if a few simple rules are followed. Move slowly. If in doubt of the
terrain, dismount and check it out first on foot. Do not attempt to
negotiate washes without first checking the footing and the clear-
ances. High centers may rupture the oil pan. Overhang may cause
the driving wheels to become suspended above the ground. In
marsh or sand, the wheels may sink in resulting in a high center
and loss of traction. Do not spin wheels in an attempt to gain
motion, but apply power very slowly to prevent wheel spin and
subsequent digging in. When driving in sand or snow, traction
can be increased by partially deflating tires. Drive slowly on
low tires. Do not remove so much air that the tire may slip on-
the rim. Start, stop and turn gradually, as sudden motions cause
wheels to dig in. If you plan on driving in the desert, practice
“difficult traction” in a dry wash with another car standing by to
tow you out if you become stuck. Experiment with the various
footings. There are certain tool and equipment requirements if
you intend to drive off the main roads: one or more shovels, a
pick-mattock, a tow chain or cable, at least 50 feet of strong tow
rope, tire pump, axe, water cans, gas cans (both filled), and of
course, your regular spare parts and auto tools. For rope, consider
nylon rather than manila. It costs more, but has twice the
strength, will last much longer, and its elasticity is highly bene-
ficial in extracting stuck vehicles. ¾” nylon has a working
strength of 2,000 pounds and a breaking strength of about 10,000
pounds. Be sure that your car is in sound condition with a full
gas tank, a filled clean radiator, a filled battery and new (and
extra) fan belts. If you become stuck or your car breaks down,
RAISE THE HOOD and STAY WITH THE CAR.
Aviators: File a flight plan before flying cross-country. When
flying across the desert be sure that you have a survival kit and
clothing suitable for ground conditions. If you have difficulty, a
crash landing is preferable to parachuting, as you may have
trouble locating the plane later. Land before you are completely
out of gasoline — dead stick landings in desert terrain are dan-
gerous. Also you will have gasoline with which to start signal
fires. Build fires well away from the plane — remember the gusty
desert winds. It may be best to remain at the plane instead of
trying to walk out. You can survive longer without water in the
2
3

-------
shade of the plane’s wing than you can by exhausting yourself
walking. Walk out only if you are sure you can reach help easily,
and are absolutely sure that you have enough water to make it.
If you decide to walk, make a careful plan, and follow the path-
finding instructions.
Direction Finding: Haven’t you awakened in a strange area
to find that you are “turned around”? The sun rises in the
east and sets in the west regardless of your first impressions.
Stand with your right hand to the morning sun or your left
hand to the evening sun and you will face North. When first ar-
riving in new country look around, study the land masses, and fix
the directions well in your mind. When moving through new
country continue the practice of fixing direction and of looking
all around you. A slow, careful trip out will assure a rapid and
safe return.
Use of the Compass: A good compass, (one with a protected
face is best) is a must for traveling in strange country. Check it
out at the same time you are making your mental notes of direc-
tion and prominent land features. To orient the compass, hold it
horizontally so that the needle swings freely. When the needle
comes to rest, rotate the compass so that the needle on the dial
and North coincide. Remember that this direction is Magnetic
North and may vary from true North by an appreciable degree.
Compare the needle direction with the North Star to learn the
difference, or you can determine this “declination constant” from
a map of the area. This deviation varies with location. Avoid
orienting your compass near any iron or steel as these will cause
swinging of the needle and incàrrect readings. To use the compass,
orient it, then determine the reading to a distant land mark in the
direction you want to go. To return, orient the compass, subtract
180’ from the outgoing reading, and move in the direction of the
calculated “back sight”. This will not necessarily return you to
your exact original location, but if you have made your mental
notes before leaving, have kept some idea of how far and how
fast you have traveled out, you will be on familiar ground in due
course upon returning.
Determining Direction Using a Watch: The watch must tell
nearly correct sun time, not daylight savings time. Hold the watch
horizontally, point the hour hand at the sun. South will be mid-
way in the smallest angle between the hour hand and the sym-
bol 12. On cloudy days a stick held upright on the center of the
watch will cast a faint shadow. Align the shadow over the hour
hand, then North will be haiL way through the small angle be-
tween the shadow and the symbol 12.
Determining Direction From the Stars: The only star which
appears stationary is Polaris, the North Star. Learn to recognize
it, and the Pointers and other star arrangements which will guide
the eye to the North Star. Examine the sky each night for some
time before going into the field. This acquaintance will giv,e one a
sense of confidence for night travel if it becomes necessary. Take
into account that the night sky, at a given hour each night, will
have shifted a little, as well as appearing to rotate during the
night. When traveling use a star close to the horizon as a guide,
but remember that the earth rotates 15 degrees every hour, so
that you must adjust or use a new guide every 10 minutes or so
in order to maintain an intended direction.
Determining Direction from Shadow: Select an object at least
three feet high which casts a shadow with a w?1l defined projec-
tion. Mark the shadow tip — wait 10 to 15 minutes and again mark
the shadow tip. A line drawn from the first mark through the
second mark will point East. Effective from about 9 a.m. to 3 p.m.
Determining Direction From Nature: Trees may have moss
which will be predominantly on the north and northeast sides of
the trunks. Check a number of trees to get a good average direc-
tion reading. The tips of evergreens generally point toward the
rising sun, approximately east. The plane on top of the barrel
cactus slants usually toward the southwest. A noon-day shadow
points north.
Navigational Hazards: The heat and high evaporation rate
of the desert cause a phenomenon known as “mirage”. The vary-
ing density distribution of the layers of hot air, usually close
to the earth’s surface, causes light rays to reach the observer
along several paths causing distorted, multiple or sometimes in-
verted images. These “heat waves”, hamper your vision, making
it difficult to determine distance or objects. It may cause objects
or land marks to change shape, disappear or cause them all to
appear alike. Another type of mirage is the false dawn of the
desert, which seems to make the sun rise in the west. Ground haze
is a layer of warm, dusty air close to the ground which hampers
and distorts vision.
SIGNALS: The best signals are fire — a huge bright one at
night, a smoky one by day, black smoke if the country is light
colored, white smoke if the country is dark. Maintain a good
supply of fuel to give the appropriate signal. Build your signal
fire on the highest point near to your shade or shelter. If fuel
is plentiful two fires some distance apart are better than one, and
three fires in a triangle denote “HELP!”
The signal mirror is an excellent device for attracting atten-
tion, particularly of aircraft. They can be obtained at military
or camping equipment stores, and the directions are included.
It is a 2-faced metallic mirror with a hole in the center. You can
improvise one from a can lid which is shiny on both sides. To
use, hold the mirror about three inches in front of your face, and
4

sight through the hole on the object you are trying to signal.
Move the mirror so that the light spot on your face, which you
can see in reflection, disappears in the hole in the mirror while
still maintaining sight of the plane, etc., through the hole. On a
clear day ground signals may be transmitted for 10 miles, signals
to aircraft an even greater distance.
Aluminum foil is an excellent signaling material. Signs may
be made of piled brush, rocks, tree branches, stomped-down snow,
etc. Make large characters running north and south to cast the
best shadow. Pilots understand these signals:
I —Need Doctor f’—Going Thi& Way
Il—Need Medicine LL—A1l Is Well
X —Unable To Proceed N—No
F—Need Food-Water y—Yes
—Need Firearms
K—Which Way
Signals made by sound are the least effective. Three of what-
ever sound you can make denotes “Distress.” A “thunderer” type
whistle is recommended as an easy way to make a lot of noise.
Blowing across the mouth of an empty large-caliber cartridge case
makes a distinctive sound. If you have a firearm, shoot once, wait
10 seconds and fire twice more about 5 seconds apart. The first
will attract attention and the second and third will give direction.
If there is no answer save your ammunition. Sound carries best
during the early evening quiet just before dark.
CLOTHING AND EQUIPMENT
Clothing: Clothing requirements will vary considerably with
the season and the environment. For the hot desert, light weight
and light colored clothing which covers the whole body is best.
Long trousers and long sleeves protect from the sun, help to pre-
vent dehydration and protect against insects, abrasions and lacer-
ations by rocks and brush and tend to reduce infections caused
by these injuries. Headgear should provide all around shade as
well as eye shade. Shoes should be light weight but sturdy, and
should protect the ankles. Remember thorns and spines make
walking a problem. Woolen socks are recommended, and spare
socks should always be carried. Gloves are helpful to protect
hands from spines and thorns when handling brush and fire-
wood. Winter clothing requirements for the southwest vary with
the altitudes in which you are operating. Also in winter, keeping
dry is important. The “layer” system is best. Several light gar-
ments are easily carried and are more versatile in varying tem-
peratures than are heavier garments, and will prove at least as
warm. They should be selected for size, keeping in mind that
other clothing may be placed over or under them. A light weight,
water repellent, wind breaker should be available to wear alone
or over the layers. A coat style is best as it will protect the hips.
Headgear should shade the eyes and some provision s iould be
made to protect the ears. Earfiaps in the headgear are probably
best and are always available. Footgear should be sturdy, protect
the ankles, and be water repellent. Do not grease shoes—it makes
them cold, tends to rot the leather, and does not waterproof them.
Silicone preparations are excellent, easy to apply, and lasting.
Woolen socks are again recommended, and spare socks should
always be carried. In winter it is important to keep the feet dry
to help prevent “trench foot” and frost bite. Damp socks can be
carried inside the shirt front against the body to dry them out.
Equipment: Your method of travel will dictate in large part
the equipment to carry. When traveling by auto you will carry
“pioneer” gear such as shovels, picks, heavy rope, etc. You must
also think about bedding, cooking gear, can opener, eating uten-
sils, flashlight with spare batteries, lantern with fuel, First Aid
kit, towels, soap, toilet paper, tissues, paper napkins, old news-
papers. These are the same items to be included when setting
up the home shelter against disaster. In this section, however,
we are primarily interested in those items to be carried by the
individual on foot, whether engaged in recreational activity or
a survival problem, such as “walking out” from a downed aircraft
or disabled vehicle.
Survival Kit: Kits are outlined, in many writings on survival.
The following items are listed, we think, in the order of their
importance. Detailed use is omitted here, but learn to use and
practice with each item BEFORE you need it for survival:
1. Knife—a good small one of the “boy scout” variety is best.
2. Matches—12 or more, strike anywhere, waterproofed by
coating with parafin, beeswax, fingernail polish, etc.
3. A small magnetic compass. Learn to use it.
4. A “thunderer” whistle. Carry it on a line around the neck.
5. A small metal signaling mirror.
6. A small magnifying lens—used to start fires, and as aid in
removing small spines or splinters.
7. A large-eyed needle. For first aid and sewing purposes.
Keep from rusting.
8. Cobbler’s linen thread. A hundred feet or more, 8 strand.
Used to set snares, build shelter, repair or improvise clothing, etc.
9. Nylon chiffon. A piece about a yard square, bright orange
color, to be used for signaling, for straining dirty water, or as a
face covering during sand or dust storms.

10. Aluminum foil. About five feet of the 12 inch heavy duty
pe, used for signaling, a reflector for fire or candle, to make a
cooking pot or a drinking cup.
11. Water purification tablets. 10 or more. Iodine-type tablets
are probably best. Seal carefully in plastic foodwrap to keep dry.
12. Toy balloons. Three or four of the large, heavy, bright
orange-colored ones. Used for emergency water containers or for
signaling. Wrap in plastic food wrap to preserve.
13. Candle stub—used for. light or as an assist in starting fires
— helps to conserve matches.
14. A single-edged razor blade. A handy first aid tool. Leave in
the original package to prevent rusting.
15. Pencil stub. Assist rescue parties by leaving notes.
16. Cigarette papers. A book of these for writing notes, or to
leave as trail markers.
17. Adhesive tape. About 2 feet, 1 inch wide, primarily for first
aid purposes. Bandaids are handy, too. Replace every few months.
18. Fish hooks. Five, assorted sizes. Use a little bait to snare
birds, etc.
19. Box nails. About five, blunted and bent to hook shape, to
be used as snare triggers.
20. Flint and steel fire starter. Make by. attaching a lighter flint
to the end of a small sturdy stick. Wrap a length of cobbler’s
linen around the stick. To make a fire, fuzz the end of the linen,
position the fuzz at the flint and strike against steel. The fuzz will
catch the spark and can be blown into a flame. Practice with it.
A cigarette lighter will provide sparks. Do not depend on having
fluid in it when you need it, and ordinary lighter wick will not
flame when dry.
All of the above items can be fitted into a tobacco tin, a band-
aid box or a similarly sized plastic box and be ready to go at any
time. Check it from time to time and be sure all items are there
and in good condition.
Other items that should be carried on the individual are: a
sharp belt knife, a good map of the area, thirty or more feet of
nylon parachute shroud line, canteen, a watch, a snake bite kit, a
firearm and ammunition, and such other items which may be
small and useful. Consider carrying your gear in a small rucksack
or pack over your shoulders. Weight carried in this manner is less
tiring than if carried in pockets or hung on the belt. The pack can
be used to sit upon. It also affords a safer method of carrying
those things, such as the belt knife, hatchet, etc., which may lend
to the chances of injury in case of a fall.
HEALTH HAZARDS
Much thought must be given to protecting your health and
well being, and the prevention of fatigue and injury: first, be-
cause medical assistance will be some time and distance away;
second, because conditions are usually different and distinct from
your everyday living. The desert is a usually healthy environ-
ment due to dryness, the lack of human and animal wastes, and
the sterilizing effect of the hot sun. The higher elevations will
also present an environment conducive to good health, since the
major part of human disease is transmitted through respiratory
action or through contact: Therefore, your immediate bodily
needs will be your first consideration.
If you are walking or active, rest 10 minutes each hour. Drink
plenty of water, especially early in the morning while the tem-
perature is still low.
While on the desert or in snow, wear sun glasses to protect
your eyes from glare. Even though the glare does not seem to
bother you, it will impair your distant vision and will retard
your adaptation to night conditions. If you have no glasses make
an eyeshade by slitting a piece of paper, cardboard or cloth. Ap-
plying charcoal or soot around the eyes is also beneficial.
Use chapstick or grease on lips and nostrils. Do not “lick” your
lips if they are dry as this will hasten splitting.
Change your socks regularly even though you must change to
used socks. Sunning and aeration of socks and underclothing
have a marked freshening value.
Do not remove your clothing in an attempt to keep cool. This
will only hasten dehydration, as will sitting on the hot ground.
In winter, do not sit down if• your clothing is damp or you
have been perspiring unless you have additional clothing or a
fire. If you have neither, walk slowly around a tree or in a circle
where ground is level and footing good until you dry out.
Do not travel in storms. Mark your direction of travel and
find shelter. Dust storms can be seen before their arrival. If on
foot, lie down with your back to the wind. Cover your head with
a cloth to keep dust out of your eyes, nose, mouth and ears. If
driving, stop and get off the road as far as possible to avoid col-
lision. Turn out lights and turn on emergency flashers. Back
vehicle into the wind to prevent sand pitting of windshield.
In a survival situation everything that you do, each motion
that you make, and each step you take must be preceded by the
thought: Am I safe in doing this?

The importance of temperature reduction to the survivor is
highlighted by the following in Chart A: Temperature 120 , water
available 2 quarts, days of expected survival 2; reduce the
temperature to 100’, and 2 quarts of water will extend your life
expectancy THREE TIMES. This importance to a potential “sur
vivor” cannot be overemphasized. Night travel, or better, NO
TRAVEL, is stressed.
At equal temperatures, the body requires two to three times
as much water to maintain water balance in the desert as it
requires in the jungle with its high humidity.
Dehydration An increase in body temperature of 6 to 8
degrees above normal (98.6) for any extended period causes death.
Body temperature in a healthy person can be raised to the’danger
point either by absorbing heat or by generating it. The body
absorbs heat from the air if the air is above 92 degrees Fahrenheit.
Direct sunlight striking the body, will increase temperature even
if the air is cool. You can also absorb heat reflected from the
ground or absorb it directly from the ground by contact. Any
kind of work or exercise increases body heat.
The body gets rid of excess heat and attempts to keep the
temperature normal by sweating, but when you sweat the body
loses water and dehydration results. It has been proven that
you can do twice as much work or walk twice as far with suffi-
cient water and normal temperatures as you can after you lose
1½ quarts of water by sweating under 100 degree temperature.
No permanent harm is done to a man who dehydrates up to
10% of his weight. IF, later he drinks enough water to gain it
back. However, 25% dehydration at temperatures in the nineties
or above, will probably be fatal. You can drink cool or warm
water as fast as you want, but ice cold water may cause distress
and cramps.
Symptoms of Dehydration: Only by the ability to recognize
the initial symptoms of dehydration can one logically expect to
take corrective measures to prevent further (and possibly fatal)
dehydration. Learn these symptoms:
Thirst discomfort, slow motion, no appetite, and later nausea,
drowsiness, and high temperature. If dehydration is from 6 to 10
per cent, symptoms will be: dizziness, headache, dry mouth, diffi-
culty in breathing, tingling in armsand legs, bluish color, indis-
tinct speech and finally, inability to walk.
Prevention of Dehydration: Thirst is not an indication of
the amount of water you need. If you drink only enough to satisfy
your thirst, you can still dehydrate. Drink plenty of water, espe-
cially at meal times and during the cooler early morning hours.
A pebble or small coin carried in the mouth will alleviate the
sensation of thirst, but is not a substitute for water and will not
aid in keeping your body temperature normal. Avoid smoking
as it encourages oral breathing exposing large areas of mucous
membrane to drying influences, thereby increasing the rate of
dehydration and need for water. Salt will do you definite harm
unless plenty of water is available. Don’t worry about salt but do
try to keep up the water intake.
Ration Sweat, Not Water: In hot deserts you need about a
gallon of water a day. If you walk at night, you may get about
20 miles for that gallon, but if you walk in the daytime heat,
you will get less than 10 miles to the gallon.
Keep your clothing on, including shirt and hat. Clothing helps
ration your sweat by slowing the evaporation rate and prolong-

ing the cooling effect. It. also keeps out the hot desert air and
reflects the heat of the sun. Stay in the shade during the day. Sit
on something 12 or more inches off the ground, if possible. DO
NOT LIE ON THE GROUND as it can be 30 degrees hotter than
a foot above the ground. If travel is indicated or necessary, travel
slowly and steadily.
Rationing water at high temperatures is actually inviting
disaster because small amounts will not prevent dehydration. Loss
of efficiency and collapse always follow dehydration. IT IS THE
WATER IN YOUR BODY THAT MAINTAINS YOUR LIFE
NOT THE WATER IN YOUR CANTEEN.
KEEP THE MOUTH SHUT and BREATHE THROUGH THE
NOSE to reduce water loss and drying of mucous membranes.
AVOID CONVERSATION for the same reason. If possible, cover
lips with grease or oil. ALCOHOL IN ANY FORM IS TO BE
AVOIDED as it will accelerate dehydration. Consider alcohol
as food and not as water since additional water is required to
assimilate the alcohol. For the same reason, food intake should
be kept to a minimum if sufficient water is not available.
Carrying Water: When planning to travel give your water
supply extra thought. Carry enough water based on the charted
requirements. Do not carry water in glass containers. These
may break. Metal insulated containers are good, but heavy. Carry
some water in gallon or half-gallon plastic containers similar to
those containing bleach. They are unbreakable, light-weight and
carrying several will assure a water supply if one is damaged.
Finding Water in the Desert: If you are near water it is
best to remain there and prepare signals for your rescuers. If no
water is immediately available look for it, following these leads:
Watch for desert trails—following them may lead to water or
civilization, particularly if several such trails join and “arrow”
downward toward a specific location.
Flocks of birds will circle over water holes. Listen for their
chirping in the morning and evening, and you may be able to
locate their watering spot. Quail fly toward water in the late
afternoon and away in the morning. Doves flock toward watering
spots morning and evening. Also look for the diggings and brows-
ings of wild animals as they tend to feed near water.
Water may be found at the base of rock cliffs for some time
after a rain. It may be found in the waste rock at the base of
cliffs or in the gravel-wash from mountain valleys which get
regular seasonal rains. Limestone and lava have more and larger
springs than any other type rocks. Springs of cold water are
safest. Limestone caverns often have springs, but remain in sight
of the entrance as you may get lost. Look for springs along walls
of valleys that cross the lava flow. Springs may be found along
valley floors or down along their sloping sides. See if there is
seepage where the dry canyon cuts through a layer of porous
sandstone. Dr’ ’ stream beds may have water just below the sur-
face. Look at the lowest point on the outside of a bend in the
stream channel. Dig until you hit wet sand. Water will seep out
of the sand into the hole. Damp surface sand marks a place to dig
a shallow well. Dig at the lowest point and go down 3 to 6 feet. If
the sand stays damp, keep digging. Look at h4llsides to see where
the grass is lush and green. Dig at the base of the green zone and
wait for water to seep into the hole. Water is more abundant
and easier to find in loose sediment than in rocks. Look for a wet
spot on the surface of a clay bluff or at the foot. of the bluff and
try dgging it out.
Look for the “indicator” plants which grow only where there
is water: cottonwoods, sycamores, willows, hackberry, saltcedar
(tamarisk), cattails and arrow weed. You may have to dig to
find this water. Also keep on the lookout for windmills and water
tanks built by ranchers. If cactus fruits are ripe eat a lot of them
(see section on foods), to help prevent dehydration.
The immature flower stalks of Agave, Yucca and Sotol con-
tain moisture, or if no flower stalks are present the main stalks
may be split open and the pith chewed to prevent dehydration.
The barrel cactus contains a high degree of moisture, but to
press out water is pure myth, as the mucilaginous, acrid juice
thickens rapidly. To remove moisture che.w on the pith but do
not swallow it. Carry chunks of the pith with you to suck on to
alleviate thirst. Young plants six to eighteen inches in height,
and with a soft green color will have the higher moisture content.
The root of the night blooming cereus is also high in moisture.
Methods of Purifying Water: Dirty water should be filtered
through several layers of cloth or allowed to settle. This does not
purify the water even though it may look clean. Incidentally,
radioactive fallout is dirt and most can be removed from water
as above. Purification to kill germs must be done by one of the
following methods:
1. Water purification tablets are the easiest to use. Get them
from the drug store and follow the directions on the label. Not
only do you need them in your survival kit and in your car or
plane, but you should keep an emergency supply at home. Gen-
erally, one tablet is sufficient for one quart of clear water or two
tablets for cloudy water. Let stand for thirty minutes.
2. Tincture of Iodine; add three drops per quart of clear water,
double for cloudy water. Let stand for thirty minutes.
3. Household bleach (5.25% sodium hypochlorite): 2 drops per
quart of clear water, 4 drops per quart of cloudy water. Stir, let
stand 30 minutes. Water should have a slight chlorine taste.

4. Boiling for 3 to 5 minutes will purify most water. Add char-
coal while boiling to remove disagreeable odors from water. Ag-
itate to aerate and restore taste or add a small pinch of salt.
DESERT STILL
An interesting method of acquiring water is through the use
of a solar still constructed generally as shown. The sun’s rays heat
the ground inside the hole, causing evaporation of the soil’s mois-
ture, which saturates the air space and condenses on the cooler
plastic surface. This method will produce some water in even the
driest areas, but by selecting a site where there are indications of
moisture—greener or more plant life, loam soil, damp sand, etc.
—about two to three pints per day may be obtained. Several such
stills would have to be constructed to provide the amount neces-
sary for continued survival. Cacti and other plants which contain
moisture may be broken up and placed in the hole to provide a
higher water recovery rate. Saguaro, barrel and prickly pear cacti
are best for this purpose. Non-potable water may be poured into
a trench around the inside of the hole and be distilled, and made
safe for drinking by the process. If non-potable water or plant
materials are placed in the hole, be sure that they do not come in
direct contact with the plastic, as the water forming on it would
then be contaminated.
The basic requirement for constructing the still is a six-foot
square or circular sheet of “wettable” plastic. The plastic material
should be a thin (1 mu), tough, rough-surfaced type, of which
duPont’s “Tedlar” is an example. Smooth plastics are less “wet-
table”, and the droplets forming will not adhere and run down to
the point of the cone before dropping off. If a smooth type must
be used, slight abrading with scouring powder, fine sand or sand-
paper will improve its wettability. Be sure the roughened side
is placed down. A wide-mouth container of some kind is used to
collect the distilled water.
The site must be in full sunshine to be efficient, although an
established still will produce some water during the night. The
hole may be dug with a sharp rock or stick, and soil removed by
hand if a shovel is not available. If the container catching the
water is non-rigid, the bottom of the hole must be shaped to
support the container as it becomes filled.
The still may become a source of food, as lizards, snakes and
small animals will fall into the cone and become entrapped.
LEGEND:
1. Sheet of wettable plastic, 6-foot diameter
2. Smooth, fist-sized rock for forming cone of plastic.
3. Pail, jar, can, or cone of foil, plastic or canvas to catch water
4. Drinking tube, 1/4 inch plastic, about 5 feet long. Desirable
but not necessary
5. Soil to weight plastic sheet and seal space. A good closure is
important
6. Line hole with broken cacti or other succulents
7. If non-potable water is available, dig a soaking trough
around inside of hole. Carefully fill the trough to prevent
impure water from running down and contaminating the
water-catching container.
FOOD
You must have water to survive, but you can go without food
for some days without harmful effects. In fact, if water is not
available do not eat, as food will only increase your need for
water. The important thing about locating food in a survival
situation is to know what foods are available in the particular
environment and how to go about obtaining them. Hawks soaring
overhead may mean rabbits or other rodents below; birds flock-
ing may mean not only edible berries but will probably mean
water nearby. Game will be found around water holes and in
areas that are prominent because of heavier brush growth.
Food List: When planning, include those items which have
high energy value, long shelf life and little weight. Generally,
meats have higher energy value than vegetables. Th dehydrated

Survival Rations:
Here is a survival ration, originally developed by the late Mr.
Lee Kelly, Survival.Expert, -which is tasty and which will pro-
vide enough ‘food for 2 days in an emergency:

be placed in the oven and dried under very low heat, then
wrapped in foil and stored indefinitely. Each bar will provide
about 1,000 calories and is sufficient food for one day. It can .be
eaten dry or cooked with about 2/3 of a canteen cup of water.
Edible Wildlife: Almost every animal and reptile, and many
insects are edible, and many are sources of highly esteemed foods.
Learn now to prepare the various things that would be available
to you in a survival situation, Avoid any small mammal which
appears to be sick as it may have tularernia, a disease trans-
mittible to humans. A spotted liver in the animal is also an indi-
cation of this disease. Some animals have scent glands which
must be removed before cooking. Do not allow the hair of these
animals’ to come in contact with the flesh as it will give the meat
a disagreeable taste. -
1. Jack Rabbit: A hare, with long- ears and legs, sandy color,
may weigh up to 8 lbs. Grubs are often found in the hide or flesh
but these do not affect the food value.
2. Cottontail Rabbit: Small, pale gray with white tail. Active
in the early morning and late evening.
3. Pocket Gopher, Kangaroo Rat, Wood Rat, Pocket Mouse,
Grasshopper Mouse: Active at night.
4. Ground Squirrel, Tree Squirrel, Chipmunk: Out during
the day.
5. Porcupine: Singe the quills, then skin and roast or boil.

27. Fish.
28. Bullfrogs: Skin before cooking.
29. Snakes: Most snakes are edible. Rattlesnake is especially
good. Remove the head and bury it as a safety precaution. How-
ever, leaving the head on is not detrimental to the eating qualities.
30. Lizards: Many species, all believed edible, including the
poisonous Gila Monster.
31. Desert Tortoise.
32. Lubber Grasshopper; 2½ inches long. Should be cooked.
33. Grubs: Found under bark, in rotten wood or in the ground.
Boil or fry.
34. Hairless Caterpillars: Hairy ones may be poisonous.
Preserving Surplus Meat: It is surprisingly easy to preserve
surplus meats in the desert southwest because of the bright sun
and dry heat. You can make Charqui (Jerky) from fat free meat
of large animals, by slicing it into strips about 1 inch thick by
several inches wide, and hanging it in the sun for two or three
days until it is completely dry. May be eaten dry or soaked and
cooked. Will keep indefinitely. Sand dried meat is similarly
stripped, then wiped dry, and buried, unsalted in dry sand about
6 inches deep. If kept dry will keep for several years. Eat dry or
soak and cook. Smoke drying is also simple. Build a lattice about
3 feet above a slow burning fire, lay ¾ inch thick strips of meat
on the lattice. Smoke until the meat becomes brittle. Do not let
the fire become so hot that the meat cooks or draws juices—the
smoke does the trick. Do not use pitchy or oily woods as they
will flavor the meat.
Snares, Traps, Deadfalls: Learn to design and use these from
books on Woodcraft. Most are simple devices which require only
ingenuity, a pocket knife, a bent nail and a piece of string. You
will have these things in your survival kit—or you may have to
improvise. Snares should be placed after camp is set up but before
dark. A twitch-up snare jerks the animal into the air, kills
promptly and protects it against other animals. A noose of string
laid around a hole or burrow can be jerked by hand as the animal
puts its head out of the hole. Conceal yourself some distance
away so that the animal in the hole cannot see you, Deadfalls are
traps which allow a heavy object, log or rock to drop on the
animal when a trigger is released. Any sized animal may be killed
by this method if the trap is large enough. Slings or slingshots
may be used to kill birds or small animals. A handful of pea-sized
rocks flung by hand may get a bird as a last resort.
Set snares in game trails or frequently used runways which
can be recognized by fresh tracks and droppings. The spot used
for butchering will attract other animals and will be a good place
to watch for a day or so. Use entrails for bait. Place the snare in
the narrowest part of the trail, or arrange obstacles to force the
animal to pass through the snare. Disturb natural surroundings
as little as possible. Be sure the noose is large enough so that the
head but, not the body of the animal will pass through.
Edible Plants: A visit to the Phoenix Botanical Gardens in
Papago Park or similar arboretum will afford you much interest-
ing information regarding desert plants.
The main desert edibles are the fruits of cacti and legumes.
All cactus fruits are safe to eat. In the summer the fleshy and
thin-walled ripe fruits can be singed over fire to remove spines.
Then they can be peeled and eaten. Old cactus fruits contain seeds
which can be pounded between two stones into a powder and
eaten, or mixed with water into a gruel called pinole. New, young
pads of the prickly pear can be singed, peeled and boiled.
The legumes are the bean bearing plants. The main ones are
the honey and screwbean mesquites, the palo verde, the tesota
(ironwood) and the catciaw acacia. All are small trees with fern-
like leaves. The palo verde is recognized by its open growth,
greenish bark and feathery leaves. Ironwood has rough, dense
growth, and will grow into a large tree under favorable condi-
tions. Catciaw is a small, grayish tree with numerous short
curved thorns. All have bean pods which when green and tender
can be boiled and eaten. Dry, mature beans, like cactus seeds, are
too hard to chew and must be cracked to be digested.
The night blooming cereus looks like a cluster of weather
beaten sticks and is found close to trees and bushes; has a larger
edible, beet-like root. Slice the root and fry. This root has a very
high moisture content, and may be used as a water source.
Other edibles are the fruits of: the tomatillo or squawberry, a
stiff thorny bush with small berries which are rather citric-tasting
and much liked by birds: the hackberry, a small tree with tiny
thick-growing roundish leaves and small red berries; Jojoba (the
goatnut or wild hazel) is a smallish shrub, with thick-growing
acorn-like nuts which were once a staple food of the Indians. In

Wild Poisonous Plants:
less arid areas burdock, cattails, dandelions, dock, lambs-quarters,
miner’s lettuce, nettles (young), water cress are a few of the
more desirable edible plants. Acorns (may be dangerous if eaten
in large quantities) pinion nuts, pine kernels, red berries, and the
young bark of aspen, cottonwood, pine and spruce are all edible.
Poisonous Plants: The identification of all poisonous plants in
Arizona (there are more than 700 in the United States and Can-
ada) is beyond the scope of this small manual. The reader is en-
couraged to study the matter further based on his degree of in-
terest. There is no pattern of geography, habitat, relationship,
seasonal appearance or plant part than can be used successfully
to separate poisonous plants from the harmless ones. The poison
principals contained are many, and effects (and treatment)
varied. A few of those common and important in our Desert
Southwest, regardless of their particular environment, are listed:
Cultivated Poisonous Plants Common to Inhabited Areas:
1. Castor Plant: A large plant with broad leaves, reddish,
burr-like seed pods and van-colored beans. All parts are toxic
(but the oil of the beans is not).
2. Oleander A common large woody hedge shrub with red,
pink or white flowers. A single leaf can be lethal to a child. Meat
skewered on Oleander branches can kill.
3. Poinsettia: The common Christmas plant with red leaves.
Contains an acrid, burning, milky juice that may cause severe
intestinal injury.
4. Dumbcane, Caladium and Philodendron: Decorative plants
often seen in lobbies, offices, etc. Contain small needlelike crys-
tals. Biting irnbeds the crystals in the tissues of tongue and
mouth resulting in intense burning and irritation which is not
dangerous in itself. Swelling of tissue at the base of the tongue
may cause death through suffocation.
5. Lantana: A common decorative shrub with small clusters
of red and orange, yellow or lavender flowers and a minty odor.
Much planted around shopping centers and commercial buildings.
All parts are poisonous.
6. Privet: A common hedge plant. The berries, especially,
are poisonous.
7. Larkspur, Monkshood, Delphinium: Cultivated or wild
plants with spikes of attractive blue flowers and milky juice.
8. Rhubarb: A common vegetable, the leaf stalk of which is
used as food. The leaf blade, however, contains a poisonous acid.
9. Potatoes: A close relative to the deadly nightshade. Heal-
thy tubers are harmless, but there is some danger in sprouts, in
rotting potatoes, in the green sunburned areas of potatoes grown
at the surface of the ground, and in the vines.
10. Nightshade (Ground Cherry, Wild Potato, Horsen ttle):
A low shrub resembling the potato plant. Has grayish leaves,
purple flowers and yellow fruit which turn purple as they ripen.
One species is yellow-flowered and fruit and plant are covered
with spines giving it the name “Buffalo Bur”.
it. Sacred Datura (Jimson Weed or Thornapple): Nightshade
family. A coarse ground vine with smelly gray-green foliage and
large trumpet-shaped white flowers. All parts are poisonous.
Children have been poisoned by sucking the nectar from the
flowers.
12. Water Hemlock (Cow Bane): Found in marshy areas and
along stream banks. The base of the stem is swollen and several
tuberous roots are attached to it. The fleshy roots have a pleas-
ant taste but are extremely dangerous.
13. Locowood or Milk Vetch: Attractive low member of the
pea family with colorful purple-white flowers and a disagreeable
odor.
14. Lupine or Bluebonnet: Also a member of the pea family
with blue-purple flowers.
15. Milkweed: A rush-like plant up to five feet in height
with green-white flowers. Leaves are short-lived. In some species
the milky sap contains much rubber. Grows on rocky slopes from
sea level to 2,500 foot elevation.
16. Coral Bean: Medium-sized shrub recognized in early sum-
mer by its leafless branches and bright red flowers; in mid-sum-
mer by its small triangular leaves and in late summer and fall
by the thick pods (6-10 inches long) with the bright red seeds.
Usually found at elevations around 3,000 to 5,000 feet.
17. Jatropha or Limber Bush: A low shrub with heart-shaped
leaf blades and flexible branches, found on rocky slopes at ele-
vations of 2,000 - 3,000 feet. Sometimes called “Sangre de drago”
because of the reddish sap in the roots. The seeds are laxative.
18. Mushrooms: Most are edible, but eat only those you can
positively identify. Do not eat those which have these charac-
teristics; a veil or fringe around the upper part of the stem; a
bag or cup at the base of the stem; a white or green spore deposit
which drops out of the gills; scales on the cap.
In a survival situation where use of strange plants for food is
indicated, follow these rules: AVOID plants’with milky sap.
AVOID all red beans. If possible, boil plants which are question-
able. Test a cooked plant by holding a small quantity in the
mouth for a few moments. If the taste is disagreeable (very bit-
ter, nauseating, burning) do not eat it.

FIRES AND COOKING
Clear an area about 15 feet across, dig a pit or arrange rocks to
contain the fire. Make a starting fire of dry grass, small twigs,
shavings, under-bark of cottonwoods, etc. Place larger twigs—
about pencil size—on top. Have heavier material ready, to add,
using the smaller pieces first. Place them on the fire in a “tepee”
fashion to prevent smothering your starting fire and aid in the
formation of an up-draft. After the fire is burning well, continue
to use the tepee method for boiling but criss-cross fuel for form-
ing coals for frying or broiling.
Start your fire with a lighter, matches, or a hand lens. If you
have time practice the art of making a fire using flint and steel.
Remember, do not use up your water-proofed matches unless your
return from the field is a guaranteed fact. Here are some hints
for expeditious fire building:
Drying Matches: Damp wooden matches can be dried by strok-
ing 20 to 30 times through the dry hair at the side of the head. Be
careful to not knock off the chemical head of very wet matches
at the start of the procedure.
Tinder (all these must be dry) Under-bark of the cotton-
wood, cedar bark, dead golden rod tops, cattail floss, charred
cloth, bird nests, mouse nests, or any readily flammable material
shredded into fine fibers. Fine steel wool makes excellent tinder.
Fuzz-stick: Cut slivers into soft wood sticks so that they
adhere to the stick. Arrange them tepee fashion, with the sepa-
rated ends downward.
Quick, hot fires: Cottonwood, cactus skeletons, creosote-bush,
aspen, tamarisk, cedar, pine, spruce, dried animal dung.
Long lasting fires: Mesquite, ironwood, black jack, sage, oak.
Flint and Steel: A practicable method if you practice. Strike
steel against flint or agate, so that the sparks hit the tinder. Hold
flint against tinder to catch spark, then carefully blow into flame.
Friction Methods: The Navajo hand drill and fire plough
methods should be learned, but require proper materials and
much practice. Material for Friction Method of Starting Fires:
Yucca, cottonwood, tamarisk, cedar, willow, elm, fir.
Gun Powder: Remove bullets from two cartridges. Prepare a
hole in the ground about 8 inches deep and 4 inches across. Place
tinder in the hole and empty one cartridge case of powder into
the tinder. Load the other case into rifle, being careful not to
dump the powder out, hold the muzzle about 4 inches from the
tii er, and fire the gun. The flame will ignite the powder in the
hole and the tinder. Have all your fuel ready to add. Do not use
this method if your cartridges are limited, or you may have fire
but go hungry. Do not attempt to start the fire without a suitable
hole and tinder as the blast will blow away the material.
REMEMBER, YOU WANT FLAME FOR HEAT, EMBERS
FOR COOKING, AND FOR SIGNALS YOU NEED SMOKE
IN THE DAYTIME AND BRIGHT FIRE AT NIGHT. BE SURE
TO EXTINGUISH YOUR FIRE BEFORE LEAVING IT.
Cooking: The methods of cooking over an open fire are many,
the main limitations being available equipment, the available
food, and the ability of the cook. All methods of cooking, boiling,
frying, broiling, roasting and baking may be employed. The tech-
niques are too lengthy to describe here. The many books on
camping are full of suggestions, as are some of the pamphlets on
use of aluminum foil. Foil affords as easy way of cooking. Wrap
the prepared food inside, double fold the edges leaving some air
space inside and place on coals. Meats, vegetables, fish, sandwich-
es, and other dishes may be cooked or heated in this manner. You
can boil water or make soup in a cardboard, bark or other contain-
er of flammable material, provided you use a low fire and keep
liquid inside of the container. The part of the container above the
water line may burn if not kept moist.
POISONOUS CREATURES
There is probably more said and less truth about poisonous
creatures than any other subject. These animals and insects are
for the most part shy, or due to their nature not often seen. There-
fore, any person who has the fortune or misfortune to become
acquainted with them becomes an expert, and in due course, the
stories told become distorted. Like gossip, the finaI tale seldom
resembles the original fact. Learn the facts about these creatures
and you will see that they are not to be feared but only respected.
Visit the museums which have displays, dead or alive, of the crea-
tures—.avoid the roadside zoos with their sensational imports if
you are looking for facts.
Snakes: There are many types of snakes in the southwest but
only rattlesnakes and coral snakes are poisonous. (Side-winders
are small rattlesnakes which get their name from the peculiar
side-looping method used in moving over sandy areas.) Snakes
hibernate during the colder months, but will start appearing with
the warming trend, sometimes in early February. During, the
spring and fall months they may be found out in the daytime, but
during the summer months they will generally be found out dur-
ing the night, due to the fact that they cannot stand excessive
heat.
Rattlesnakes: These are easily identified by the sandy color,
the broad arrow-shaped head, blunt tipped-up nose, and rattles
on the tail. Look for them mostly where food, water, and pro-
22
23

-------
tection are available—around abandoned structures, irrigation
ditches, water holes, brush and rock piles. They do not always
give warning by rattling, nor do they always strike if one is
close. Usually they are not aggressive and vill not “chase”
people. They may attempt to escape from noise and commotion or
they may remain quiet and hidden. Rattlesnakes strike by rapid-
ly extending the neck and upper body loops for a distance of one-
third to one-half the total length. The poison is injected through
two curved hollow fangs which are hinged forward by the wide
opening of the mouth. The strike results in immediate pain ac-
companied by swelling. The venom primarily causes local and in-
ternal destruction and nerve damage. Severe infection is a pos-
sibilty. About 99C ’ of snake bites are in lower parts of the limbs.
If traveling in areas where rattlers are, wear protective footgear
and watch where you put your hands and feet. Improvised put-
tees of corrugated cardboard or thick newspapers underneath
trousers provide effective leg protection.
Arizona Coral Snake: A small snake, rarely over 20 inches
long with small blunt, black head and tapering tail. Wide red and
black bands are separated by narrower yellow bands and all com-
pletely encircle the body. They are nocturnal and live under
objects, in burrows, and are shy and timid. Corals bite and chew
rather than strike, but due to the very small mouth and short
(about 0.2 to 0.3 mm) fixed fangs, they are unable to bite any
but the smallest extremities. Arizona Coral snakes will bite only
under severe provocation. The venom affects the nervous sys-
tem causing failure of the heart and respiratory muscles.
Treatment of Poisonous Snakcbite: If bitten, try to capture
the snake as identification will aid in specific medical treatment.
GET A DOCTOR! Antivenin kits (Wyeth Corporation) are avail-
able. Keep a kit available for administration by your Doctor. In
acute emergency Antivenin may be self-administered. If ice is
available, use the Stahnke Ligature-Cryotherapy method as fol-
lows:
1. KEEP THE VICTIM QUIET! Immediately apply a ligature
(constricting band) of strong string, shoe lace, or similar between
the bite and the body, just above the punctures. Tighten only
until first pain is felt. Place a piece of ice on the site. Instead
of ice, Frigiderm or other spray refrigerant may be used. Do not
spray directly on the skin. Cover the site with a thin wet cloth
pad and spray with refrigerant to form ice. Re-spray as required
to maintain an effective ice pack.
2. Prepare a suitable vessel of crushed ice and. water, and
submerge the entire limb to well above the site. USE NO SALT.
3. After about ten minutes remove the ligature. Keep the
limb in ice water for at least two hours. Then,
4. Transfer the limb to a vessel of crushed ice (USE NO
SALT) for a minimum of 24 hours. Several days treatment may
be required for bites of larger snakes. Ice must not be permitted
to melt away from the body surfaces. If the bite is on the torso or
at a point of attachment of limb to body, the entire limb and body
area well above the point of attachment must.be packed in ice.
5. Keep the patient comfortably warm during the first 24
hours. Then, until treatment is• discontinued,, keep the patient
warm to the point oUmild perspiration. This is important to
prevent tissue deterioration. It is also very important that the
patient’s fluid intake be greatly increased during treatment.
6. Hypothermia, as this ice treatment is called, must be dis-
continued gradually. This is best done by again placing the mem-
ber in ice water from which the ice has been removed, and per-
mitting both to return gradually to room temperature.
Cut and Suck Method: Recent studies of the “cut and suck”
method are showing that the technique is of doubtful value. Of
about 6,000 persons bitten by poisonous snakes in the U.S. each
‘year only about 12 die and many of the survivors had no first aid
treatment whatsoever. So, if ice is not available, follow these
simple instructions: Keep the Victim Quiet! Immediately apply
a ligature as in Step 1 above. Bring the doctor to the patient.
If the “cut and suck” method is deemed necessary, follow the
instructions with the snake bite kit or Red Cross Manual. In any
event, Step 1 above, is very important. To prevent excessive dam-
age to tissues, nerves, and blood vessels, make the longer, deeper
cuts in the direction of the body tissue and the shorter cross
incision at right angles. Depth of cuts will depend on the size
of the snake and the area bitten. Do not hesitate to Luck by
mouth. Venom is not a stomach poison, and the amount one
would’ absorb through sores in the mouth would be insignificant.
To be effective, the incisions must be made immediately after
the bite, and suction applied for an hour or more. C-S employed
one-half hour after the bite has little if any value.
GiJa Monster: Our only poisonous lizard: due to the small
numbers it is protected by law. Seldom over 20 inches long, with
a beaded black and coral colored skin. They move sluggishly
but can swap ends and snap rapidly. The bite is poisonous (but
the breath is not). The neurotoxic venom is carried from g1anJ ’
in the lower jaw by grooved teeth. The poison seems to be
an anticoagulant and the wounds bleed freely. accompanied by
swelling, Death (extremely rare) results from heart and respira-
tory failure. If bitten, grab the Gila behind the head and yank off.
The teeth are not set in sockets and come out readily. Use L-C
treatment and call a doctor.
Poisonous Insects and Spiders: The potentially lethal species
in this area -are the small Rock or Bark Scorpion, the Bl ’ck
Widow Spider and the Honey Bee. The Recluse Spider bite re-
sults in serious ulceration. Bites or stings of other species may
24
25

-------
be pamful, but generally are not dangerous except that GREAT
HAZARD OF INFECTION EXISTS IN ALL CASES.
Rock or Bark Scorpion: Small, very slim, light straw colored.
The stinger in the tip of the “tail” injects a minute amount of
powerful venom. Dangerous to small children, the elderly, and
those with high blood pressure, heart or respiratory ailments.
There will be pain at the site, numbness, restlessness, fever,
fast pulse, and breathing difficulty. Healthy adults usually have
little serious reaction.
Black Widow Spider: Shiny black with red hour glass marking
on the abdomen. Found in the dark corners of sheds and out-
buildings, under logs, and in rock piles. Will bite if provoked.
Bite can be dangerous to all ages, but is seldom fatal. Pain spreads
throughout the body, accompanied by headache, dizziness and
nausea. Extremities become cramped, the abdomen becomes rigid,
pupils dilate, and spasms may occur after several hours.
Honey Bees: Honey bee “stingers” are barbed at the tip and
remain in the victim. The venom sacs are torn from the bee’s
body and remain attached to the stinger. Pinching the sac will
inject additional venom. Therefore, do not try to pull out stingers
but scrape them out with a knife or other thin edge. There. are
more deaths annually from honey bee stings than from all other
poisonous creatures combined. Hypersensitive persons or those
sensitized by previous stings (anaphylaxis) may have fatal re-
actions unless promptly treated medically. The application of
ice to the site within minutes can prevent serious results. Inform
your doctor of your honey bee sting history.
Recluse or Brown Spider: Rare in the desert. Light brown
colored, about ½ inch in length, active at night, Easily identified
by the violin-shaped marking on the “head” and back. The bite
causes local reddening and swelling, and results in an ulcerous
wound extremely difficult to heal.
Tarantula, Giant Hairy Scorpion, Desert Centipede: Not dan-
gerous but may inflict a painful bite or sting. Tarantula may pro-
duce anaphylaxis. Ants, Velvet Ants, Wasps, Hornets: May cause
a painful sting, usually not, serious. Application of strong house-
hold ammonia, Mrs. Stewart’s. liquid household bluing, or ice is
helpful in reducing pain. Conenose Bugs: Bloodsuckers may in-
ject disease-producing organisms.
Vinegaroon, Solpugid, Jerusalem Cricket: Not only harmless
but beneficial to man.
Prevention and Treatment: In places where venomous species
are expected, carefully inspect all clothing and bedding before
use, especially items that have been on or near the ground during
the night. Dampness seems to attract these creatures. During
summer evenings scorpions travel over the desert floor and up
the branches of trees and bushes looking for food. Bedding on
the ground will provide them with a hiding place toward morn-
ing. If bitten (stung) apply a ligature and ice. DO NOT cut and
suck. Remove the ligature after five minutes. Get to a doctor,
especially if the victim is a child, is elderly, has a bad heart, or
has been bitten several times or on the main part of the body.
QUICKSAND
Quicksand is a deposit of fine sand in combination with water.
It may have the appearance of smooth dry sand, but the water
underneath lubricates the grains and allows them to flow easily.
There is nothing mysterious about quicksand—it acts as any thick
liquid would, and if we react sensibly we can escape it.. Man is
lighter and will float in water, and therefore, quicksand. It has
no power to suck down bodies, but frantic struggling to free the
feet creates forceful downward movement which causes the sand
first to move away, then quickly return to pack around the legs.
The result is a firmer and deeper hold on the body. Further strug-
gling repeats the process until the body is engulfed completely.
If caught throw yourself flat on your back. You will float. Get
rid of extra weight. Throw your gun and pack off quickly. Don’t
hold up your arms—let them rest spread out on the surface. Roll
slowly to firm ground, or turn onto your stomach and do a slow
breaststroke. Move slowly and carefully, and you will “swim” to
safety. Avoid getting caught—look for quicksand in river beds,
washes and run-off areas of recent flash floods.
RABIES (Hydrophobia)
Rabies is a disease of warm-blooded animals. Domestic dogs
and cats, and many desert animals (coyotes, foxes, skunks, go-
phers, rats, bats) can transmit the disease to man by biting. If
a person is bitten by any strange animal, it is important to cap-.
ture and isolate it, if possible. The suspected animal must be
kept in isolation for fourteen days unless death intervenes, in
which case the undamaged head should be sent to the State Lab-
oratory for examination. The victim should get to a doctor as soon
as possible although start of treatment may be delayed for sev-
eral days without danger. Untreated rabies infection is always
fatal. A special warning in regard to bats: Do not pick up or
handle bats as they are believed to be the most common carriers
and transmitters of the disease.
