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

Allow vomiting to occur. When vomiting occurs, keep head lower than
hips to help prevent aspiration. If person is unconscious, turn
head to side. Get medical attention immediately. NOTE TO PHYSICIAN:
For inhalation, consider oxygen. Avoid gastric lavage or emesis.

Flash Point:No data available.
Extinguishing Media:carbon dioxide, regular dry chemical Large fires:
Flood with water. Apply water from a protected location or from a
safe distance.
Fire Fighting Procedures:Do not get water inside container. Do not
scatter spilled material with high-pressure water streams. 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.
Unusual Fire/Explosion Hazard:Negligible fire hazard.

Spill Release Procedures:Avoid contact with combustible materials. Do
not touch spilled material. Do not get water inside container. Stop
leak if possible without personal risk. Reduce vapors with water
spray. Do not get water directly on material. Only personnel
trained for the hazards of this material should perform clean up
and disposal. Dike for later disposal. Do not use water. Keep
unnecessary people away, isolate hazard area and deny entry.
Ventilate closed spaces before entering.
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 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 with a faceshield.
Provide an emergency eye wash fountain and quick drench shower in
the immediate work area.
Other Protective Equipment:Wear appropriate chemical resistant
clothing.
