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.

Extinguishing Media:Use extinguishing agents appropriate for
surrounding fire.
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 tank,
rail car or tank truck, evacuation radius: 800 meters (1/2 mile).
Unusual Fire/Explosion Hazard:Negligible fire hazard. Containers may
rupture or explode if exposed to heat.

Spill Release Procedures:Do not touch spilled material. Stop leak if
possible without personal risk. Keep unnecessary people away,
isolate hazard area and deny entry. Ventilate closed spaces before
entering.
Neutralizing Agent:

Handling and Storage Precautions:Store and handle in accordance with
all current regulations and standards. Protect from physical
damage. Inside storage: Store in a well-ventilated area. 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. 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. 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.
