Medical Cond Aggravated by Exposure:

First Aid: INHALATION: If adverse effects occur, remove to
uncontaminated area. Give artificial respiration if not breathing.
If breathing is difficult, oxygen should be administered by
qualified personnel. Get immediate medical attention. SKIN CONTACT:
If frostbite or freezing occur, immediately flush with plenty of
lukewarm water (105-115 F; 41-46 C). DO NOT USE HOT WATER. If warm
water is not available, gently wrap affected parts in blankets. Get
immediate medical attention. EYE CONTACT: Flush eyes with plenty of
water. INGESTION: If a large amount is swallowed, get medical
attention. NOTE TO PHYSICIAN: For inhalation, consider oxygen.

Flash Point:-69 F (-56 C) (OC)
Autoignition Temp:549 F (287 C)
Lower Limits:2.6%
Upper Limits:39%
Extinguishing Media:carbon dioxide, regular dry chemical Large fires:
Use regular foam or flood with fine water spray.
Fire Fighting Procedures:Move container from fire area if it can be
done without risk. For fires in cargo or storage area: Cool
containers with water from unmanned hose holder or monitor nozzles
until well after fire is out. If this is impossible then take the
following precautions: Keep unnecessary people away, isolate hazard
area and deny entry. Let the fire burn. Withdraw immediately in
case of rising sound from venting safety device or any
discoloration of tanks due to fire. For tank, rail car or tank
truck: Stop leak if possible without personal risk. Let burn unless
leak can be stopped immediately. For smaller tanks or cylinders,
extinguish and isolate from other flammables. Evacuation radius:
800 meters (1/2 mile). Do not attempt to extinguish fire unless
flow of material can be stopped first. Flood with fine water spray.
Cool containers with water spray until well after the fire is out.
Apply water from a protected location or from a safe distance.
Avoid inhalation of material ocombustion by-products. Stay upwind
and keep out of low areas. Evacuate if fire gets out of control or
containers are directly exposed to fire. Evacuation radius: 500
meters (1/3 mile). Consider downwind evacuation if material is
leaking. Stop flow of gas.
Unusual Fire/Explosion Hazard:Severe fire hazard. Vapor/air mixtures
are explosive above flash point. The vapor is heavier than air.
Vapors or gases may ignite at distant ignition sources and flash
back.

Spill Release Procedures:Avoid heat, flames, sparks and other sources
of ignition. Stop leak if possible without personal risk. Reduce
vapors with water spray. Keep unnecessary people away, isolate
hazard area and deny entry. Remove sources of ignition. Ventilate
closed spaces before entering.
Neutralizing Agent:

Handling and Storage Precautions:Store and handle in accordance with
all current regulations and standards. Subject to storage
regulations: U.S. OSHA 29 CFR 1910.101. Grounding and bonding
required. Store in a well-ventilated area. Avoid contact with
light. Store in a tightly closed container. Keep separated from
incompatible substances.
Other Precautions:

Respiratory Protection:Under conditions of frequent use or heavy
exposure, respiratory protection may be needed. Respiratory
protection is ranked in order from minimum to maximum. Consider
warning properties before use. Any chemical cartridge respirator
with organic vapor cartridge(s). Any chemical cartridge respirator
with a full facepiece and organic vapor cartridge(s). Any
air-purifying respirator with a full facepiece and an organic vapor
canister. For Unknown Concentrations or Immediately Dangerous to
Life or Health - Any supplied-air respirator with full facepiece
and operated in a pressure-demand or other positive-pressure mode
in combination with a separate escape supply. Any self-contained
breathing apparatus with a full facepiece.
Ventilation:Provide local exhaust ventilation system. Ventilation
equipment should be explosion-resistant if explosive concentrations
of material are present. Ensure compliance with applicable exposure
limits.
Protective Gloves:Wear insulated gloves.
Eye Protection:For the gas: Eye protection not required, but
recommended. For the liquid: Wear splash resistant safety goggles.
Contact lenses should not be worn. Provide an emergency eye wash
fountain and quick drench shower in the immediate work area.
Other Protective Equipment:Wear appropriate chemical resistant
clothing.
