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.

Spill Release Procedures:Stop leak if possible without personal risk.
Keep unnecessary people away, isolate hazard area and deny entry.
Stay upwind and keep out of low areas.
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:Based on available information, additional ventilation is
not required. 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.
