Reports of Carcinogenicity:NTP:No IARC:No OSHA:No
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:
Wash skin with soap and water for at least 15 minutes while
removing contaminated clothing and shoes. Get immediate medical
attention. Thoroughly clean and dry contaminated clothing and shoes
before reuse. Destroy contaminated shoes. 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:carbon dioxide, regular dry chemical Large fires:
Use regular foam or flood with fine water spray.
Fire Fighting Procedures:Do not get water inside container. 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. Keep unnecessary people away, isolate
hazard area and deny entry. 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. Containers may
rupture or explode if exposed to heat.

Spill Release Procedures:Stop leak if possible without personal risk.
Reduce vapors with water spray. Do not get water directly on
material. Do not get water inside container. Keep unnecessary
people away, isolate hazard area and deny entry. Small spills:
Flood with water. Large spills: Dike for later disposal. Stay
upwind and keep out of low areas. Ventilate closed spaces before
entering. Evacuation radius: 150 feet.
Neutralizing Agent:

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 acid gas cartridge(s). Any chemical cartridge respirator with
a full facepiece and acid gas cartridge(s). Any air-purifying
respirator with a full facepiece and an acid gas 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 or process enclosure 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.
