SECTION IV - FIRE AND EXPLOSION DATA
------------------------------------------------------------------------
FLASHPOINT: (Method Used): The flashpoint of the mixture has
been determined to be 168 F (75.5 C) by the closed cup method.
The lowest flashing component of the mixture (ethylene glycol
monomethyl ether) has a flashpoint of 115 F (46 C) by the closed
cup method.
EXTINGUISHING MEDIA: Carbon dioxide, alcohol foam, water.
Avoid use of extinguishing methods that will cause splashing or
spreading of .
SPECIAL FIRE FIGHTING PROCEDURES: Incipient fires may
be fought with a type BC fire extinguisher. If the fire cannot be
controlled, contact the fire department. All persons not engaged in
extinguishing the fire should be immediately evacuated from the
area. Fires involving DS2 should be contained to prevent spreading
to uncontrolled areas. When responding to fire alarms firefighters
should wear full firefighter protective clothing during firefighting
and rescue operations. Respiratory protection is required. Positive
pressure, full face piece, NIOSH approved self-contained breathing
apparatus (SCBA) will be worn where there is danger of oxygen
deficiency and when directed by the fire chief.
Do not breathe fumes. Skin contact with DS2 must be avoided at
all times. Care must be taken to avoid contamination of other areas
and sewers. Contact with liquid or vapors can be fatal.
UNUSUAL FIRE AND EXPLOSION HAZARDS: Never mix or
store acids, oxidizing agents, Super Tropical Bleach (STB) or High
Test Hypochlorite (HTH) together with DS2; fire or explosion may
result.
------------------------------------------------------------------------
SECTION V- HEALTH HAZARD DATA
------------------------------------------------------------------------
THRESHOLD LIMIT VALUE: DS2 is made of two major
components (EGME & DETA) with different toxicities and
physical properties. The TLV of the mixture (calculated) is 5.2
mg/m3 as an 8-hour time weighted average (TWA). To date the
Occupational Safety and Health Administration (OSHA) has not
promulgated a permissible exposure limit for DS2 nor has the value
proposed been officially adopted as a part of a special occupational
safety and health standard for DS2 according to DOD 6055.1.
EFFECTS OF OVEREXPOSURE: No toxicity data is available on
DS2, however, the toxicity of each component has been partially
determined. DS2 is an alkali and direct contact will corrode tissue,
e.g., skin, eye, respiratory mucosa or gastric mucosa. The effects
exhibited depend on routes of exposure, dosage, and duration of
exposure. Health effects can range from mild burns and primary
irritation to corneal opacification, severe burns and esophageal
strictures. Sufficient exposure to EGME, a major component of
DS2, may cause central nervous system depression and liver
damage. Although not definitely established in humans,
reproductive effects (including teratogenesis) are also a major
concern with this substance. The National Institute for
Occupational Safety and Health (NIOSH) recommends that EGME
be regarded in the workplace as having the potential to cause
adverse reproductive effects in male and female workers.
Appropriate controls must be instituted to minimize worker
exposure to EGME. Exposure to high vapor concentrations of DS2
can cause nausea, vomiting, and respiratory irritation as acute
effects. Repeated skin and respiratory exposures to DETA can
cause skin sensitization and asthma.
EMERGENCY AND FIRST AID PROCEDURES:
INHALATION: Remove to fresh air. If breathing is difficult, give
oxygen If breathing has stopped, give artificial respiration. Mouth-
to-mouth resuscitation should be used when approved mask-bag or
oxygen delivery systems are not available. Do not use mouth-to-
mouth resuscitation when facial contamination exists. Seek medical
attention IMMEDIATELY.
EYE CONTACT: Immediately flush the eyes with copious amounts
of water for at least 15 minutes. Seek medical attention
IMMEDIATELY.
SKIN CONTACT: Flush away the DS2 from the skin with water
until "soapiness" is no longer present. Seek medical attention
IMMEDIATELY.
INGESTION: If the patient is conscious, give as much milk or
water as possible. Do not induce vomiting. Seek medical attention
IMMEDIATELY.
------------------------------------------------------------------------
SECTION VI - REACTIVITY DATA
------------------------------------------------------------------------
STABILITY: DS2 will deteriorate in air. Exposure of 48 hours or
more to air will result in the formation of gelatin-like bodies on the
surface of DS2 open.
INCOMPATIBILITY: DS2 is a corrosive material and because of
its content, it is incompatible with some metals (e.g., cadmium, tin
and zinc); some plastics (e.g., Lexan, cellulose acetate, polyvinyl
chloride, Mylar, and acrylic); some paints; wool; leather; oxidizing
materials (e.g., Super Tropical Bleach or High Test Hypochlorite);
and acids.
HAZARDOUS DECOMPOSITION: Unknown
HAZARDOUS POLYMERIZATION: Unknown
------------------------------------------------------------------------
SECTION VII - SPILL, LEAK, AND DISPOSAL PROCEDURES
------------------------------------------------------------------------
STEPS TO BE TAKEN IN CASE MATERIAL IS RELEASED OR
SPILLED: Spills on porous surfaces (concrete, wood, etc.) should
be cleaned and neutralized immediately. Otherwise, they will be
absorbed and become an indefinite hazard. All spills must be
contained, by covering with dry sodium bisulfate to neutralize and
then absorbing them on vermiculite (NSN 5640-01-324-2664), clay
or diatomaceous earth. Scoop up all material and any contaminated
soil or substrate and place in a DOT approved container and label
as corrosive according to EPA and DOT requirements. Leaking
containers will be over packed with vermiculite between the interior
and exterior containers. Decontaminate the exterior container and
label according to DOT and EPA regulations. Dispose of contents
according to procedures below. Dispose of decontaminate
according to Federal, state, and local laws.
Approve containers include:
7 gal NSN - 8110-00-254-5714
27 gal NSN - 8110-00-082-2625
57 gal NSN - 8110-00-082-2626
Other NSNs can also be used provided they meet the test
requirements as specified in CFR Title 49.
During spills provide adequate ventilation and remove any ignition
source. During clean up, personnel should wear a full face
respirator with an organic vapor cartridge effective against
diethylenetriamine and methyl cellosolve, rubber gloves long
enough to protect hands and arms, and a full length rubber apron.
Contaminated clothing and shoes should be removed immediately
and washed thoroughly with water before reuse. Avoid contact with
leaking liquid or vapor. All wash water should have pH measured.
All material with a pH less than 2.0 or greater than 12.5 is
hazardous waste with an EPA number of D002.
WASTE DISPOSAL METHOD: Disposal methods for waste DS2
and accumulated spill cleanup residues must comply with RCRA,
state, and local hazardous waste regulations and procedures. If the
wastes are corrosive, they have the EPA Hazardous Waste Number
of D002. This number should be used when the waste is
manifested, to permit the use of off-site hazardous waste disposal
facilities. For disposal of excess stocks of pure DS2, coordinate
with the Defense Reutilization and Marketing Office (DRMO).
Disposal methods at overseas military installations must be
according to the laws of the host country.
