Use regular foam or flood with fine water spray.
Fire Fighting Procedures: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).
Do not attempt to extinguish fire unless flow of material can be
stopped first. Use extinguishing agents appropriate for surrounding
fire. Flood with fine water spray. Cool containers with water spray
until well after the fire is 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.
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. Notify Local Emergency
Planning Committee and State Emergency Response Commission for
release greater than or equal to RQ (U.S. SARA Section 304). If

Handling and Storage Precautions:Store and handle in accordance with
all current regulations and standards. 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 chemical cartridge respirator
with organic vapor cartridge(s). 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. 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 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.
