disorientation, convulsions LONG TERM EXPOSURE: no information is
available SKIN CONTACT: SHORT TERM EXPOSURE: no information on
significant adverse effects LONG TERM EXPOSURE: no information on
significant adverse effects EYE CONTACT: SHORT TERM EXPOSURE: 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 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:
If a large amount is swallowed, get medical attention. NOTE TO
PHYSICIAN: For inhalation, consider oxygen.

Flash Point:-49 F (-45 C)
Autoignition Temp:527 F (275 C)
Lower Limits:1.6%
Upper Limits:8.7%
Extinguishing Media:alcohol resistant foam, carbon dioxide, regular dry
chemical, water, alcohol resistant foam Large fires: Use
alcohol-resistant 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. Remove 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. Keep unnecessary people away,
isolate hazard area and deny entry. Stay upwind and keep out of low
areas.
Neutralizing Agent:

Handling and Storage Precautions:Store and handle in accordance with
all current regulations and standards. Grounding and bonding
required. Subject to storage regulations: U.S. OSHA 29 CFR
1910.106. 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 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. 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. Ventilation
equipment should be explosion-resistant if explosive concentrations
of material are present. 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.
