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 medical attention, if
needed. Thoroughly clean and dry contaminated clothing and shoes
before reuse. EYE CONTACT: Flush eyes with plenty of water for at
least 15 minutes. Then get immediate medical attention. INGESTION:
DO NOT induce vomiting. Never make an unconscious person vomit or
drink fluids. If vomiting occurs, keep head lower than hips to help
prevent aspiration. If person is unconscious, turn head to side.
Get medical attention. NOTE TO PHYSICIAN: For inhalation, consider
oxygen. For ingestion, consider gastric lavage, catharsis and
activated charcoal slurry.

Flash Point:160 F (71 C) (OC)
Autoignition Temp:770 F (410 C)
Lower Limits:0.8%
Upper Limits:5.8%
Extinguishing Media:regular dry chemical, carbon dioxide, water,
regular foam 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. For fires
in cargo or storage area: Cool containers with water from unmanned
hose holder or monitor nozzles until well after fire is out. If
this is impossible then take the following precautions: Keep
unnecessary people away, isolate hazard area and deny entry. Let
the fire burn. 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). Do not attempt to extinguish fire unless flow of
material can be stopped first. Flood with fine water spray. Do not
scatter spilled material with high-pressure water streams. 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 ocombustion by-products. Stay upwind and
keep out of low areas.
Unusual Fire/Explosion Hazard:Severe fire hazard. Vapor/air mixtures
are explosive above flash point. The vapor is heavier than air.
Vapors or gases may ignite at distant ignition sources and flash
back.

Spill Release Procedures:Avoid heat, flames, sparks and other sources
of ignition. Stop leak if possible without personal risk. Reduce
vapors with water spray. Small spills: Absorb with sand or other
non-combustible material. Collect spilled material in appropriate
container for disposal. Large spills: Dike for later disposal.
Remove sources of ignition. Keep unnecessary people away, isolate
hazard area and deny entry.
Neutralizing Agent:

Handling and Storage Precautions:Store and handle in accordance with
all current regulations and standards.
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.
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.
