Health Hazards Acute and Chronic:INHALATION: SHORT TERM EXPOSURE:
irritation, nausea, vomiting, drowsiness, symptoms of drunkenness
LONG TERM EXPOSURE: no information on significant adverse effects
SKIN CONTACT: SHORT TERM EXPOSURE: irritation LONG TERM EXPOSURE:
same as effects reported in short term exposure EYE CONTACT: SHORT

Medical Cond Aggravated by Exposure:

First Aid: INHALATION: If adverse effects occur, remove to
uncontaminated area. Give artificial respiration if not breathing.
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 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 ingestion, consider gastric
lavage. Consider oxygen.

Flash Point:39 F (4 C) (CC)
Lower Limits:9.7%
Upper Limits:12.8%
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. Water may be ineffective.
Unusual Fire/Explosion Hazard:Severe fire hazard. Moderate explosion
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:[Spills may need to be reported to the
National Response Center (800/424-8802) DOT Reportable Quantity
(RQ) is 1000 pounds] Eliminate and remove all ignition sources.
Handling equipment must be grounded to prevent sparking. Ventilate
the area of the spill or leak. For large spills, evacuate the
hazard area of unprotected personnel. Wear appropriate respirator
and protective clothing. Shut off source of leak only if safe to do
so. Dike and contain. If vapor cloud forms, water fog may be used
to suppress; contain runoff. Remove with vacuum trucks or pump to
storage vessels. Soak up residue with an absorbent such as clay,
sand or other suitable material; place in non-leaking containers
for proper disposal. Flush area with water to remove trace residue;
dispose of flush solutions as above. For small spills, take up with
an absorbent material and place in non-leaking containers; seal
tightly for proper disposal.
Neutralizing Agent:

Handling and Storage Precautions:Keep liquid and vapor away from heat,
sparks and flame. Surfaces that are sufficiently hot may ignite
even liquid product in the absence of sparks or flame. Extinguish
pilot lights, cigarettes, and other sources of ignition prior to
use and until all vapors are gone. Vapors may accumulate and travel
to ignition sources distant from the handling site; flash-fire can
result. Keep containers closed when not in use. Use with adequate
ventilation.
Other Precautions:Containers, even those that have been emptied, can
contain explosive vapors. Do not cut, drill, grind, weld or perform
similar operations on or near containers. Static electricity may
accumulate and create a fire hazard. Ground fixed equipment. Bond
and ground transfer containers and equipment.

Respiratory Protection:The following respirators and maximum use
concentrations are drawn from NIOSH and/or OSHA. 1000 ppm Any
supplied-air respirator. Any powered, air-purifying 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. Any
self-contained breathing apparatus with a full facepiece. Any
supplied-air respirator with a full facepiece. Escape - Any
air-purifying respirator with a full facepiece and an organic vapor
canister. Any appropriate escape-type, self-contained breathing
apparatus. 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 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.
