Autoignition Temp:1184 F (640 C)
Lower Limits:5.5%
Upper Limits:21.3%
Extinguishing Media:carbon dioxide, regular dry chemical Large fires:
Flood with fine water spray.
Fire Fighting Procedures:Move container from fire area if it can be
done without risk. Cool containers with water spray until well
after the fire is out. Stay away from the ends of tanks. 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 i out. Apply water from a protected
location or from a safe distance. Avoid inhalation of material or
combustion 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. The vapor is heavier
than air. Vapors or gases may ignite at distant ignition sources
and flash back. Containers may rupture or explode if exposed to
heat. Electrostatic discharges may be generated by flow or
agitation resulting in ignition or explosion.

Spill Release Procedures:Avoid heat, flames, sparks and other sources
of ignition. Do not touch spilled material. 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. Keep separated from
incompatible substances. Store in a tightly closed container.
Containers must have overpressure release device. Avoid heat,
flames, sparks and other sources of ignition. Keep separated from
incompatible substances.
Other Precautions:

Respiratory Protection:The following respirators and maximum use
concentrations are drawn from NIOSH and/or OSHA. 10 ppm Any
chemical cartridge respirator with organic vapor cartridge(s). Any
supplied-air respirator. 25 ppm Any supplied-air respirator. Any
powered, air-purifying respirator with organic vapor cartridge(s).
50 ppm 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. Any powered,
air-purifying respirator with a full facepiece and organic vapor
cartridge(s). Any self-contained breathing apparatus with a full
facepiece. Any supplied-air respirator with a full facepiece. 200
ppm Any supplied-air respirator with a full facepiece that is
operated in a pressure-demand or other positive-pressure mode.
Escape - Any air-purifying respirator with a full facepiece and an
organic vapor canister. Any appropriate escape-type, self-contained
breathing apparatus. 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:For the gas: Protective clothing is not
required. For the liquid: Wear appropriate protective, cold
insulating clothing.
