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: Immediately flush eyes
with plenty of water for at least 15 minutes. Then get immediate
medical attention. INGESTION: If a large amount is swallowed, get
medical attention. NOTE TO PHYSICIAN: For inhalation, consider
oxygen.

Autoignition Temp:1085 F (585 C)
Lower Limits:5%
Upper Limits:75%
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.
Unusual Fire/Explosion Hazard:Severe fire hazard. Gas/air mixtures are
explosive. 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.
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 supplied-air respirator with a
full facepiece that is operated in a pressure-demand or other
positive-pressure mode. Any self-contained breathing apparatus that
has a full facepiece and is operated in a pressure-demand or other
positive-pressure mode. 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 appropriate chemical resistant gloves.
Eye Protection:Wear splash resistant safety goggles. Provide an
emergency eye wash fountain and quick drench shower in the
immediate work area.
Other Protective Equipment:Wear appropriate chemical resistant
clothing.
