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.

Autoignition Temp:>1382 F (>750 C)
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. Cool containers with water spray until well
after the fire is out. Stay away from the ends of tanks. 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, evacuation radius: 800 meters (1/2 mile). Use extinguishing
agents appropriate for surrounding fire. Cool containers with water
spray until well after the fire is out. Apply water from a
protected location or from a safe distance. Do not get water
directly on material. Reduce vapors with water spray. Avoid
inhalation of material or combustion by-products. Stay upwind and
keep out of low areas. Consider downwind evacuation if material is
leaking.
Unusual Fire/Explosion Hazard:Negligible fire hazard. Containers may
rupture or explode if exposed to heat.

Spill Release Procedures:Dike the spilled liquid, and either pump back
into original container or cover with clay-type substance for
absorption.
Neutralizing Agent:

Handling and Storage Precautions:Store at ambient temperature. Prevent
possible eye and skin contact by wearing protective clothing and
equipment.
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 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.
