consider gastric lavage.

Flash Point:208 F (98 C) (SCC)
Extinguishing Media: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. Use
extinguishing agents appropriate for surrounding fire. Do not get
water directly on material. Large fires: Flood with fine water
spray. Reduce vapors with 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.
Unusual Fire/Explosion Hazard:Slight fire hazard.

Spill Release Procedures:Do not touch spilled material. Stop leak if
possible without personal risk. Small spills: Absorb with sand or
other non-combustible material. Small dry spills: Collect spilled
material in appropriate container for disposal. Keep unnecessary
people away, isolate hazard area and deny entry.

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.
