Reports of Carcinogenicity:NTP:No IARC:No OSHA:No
Health Hazards Acute and Chronic:INHALATION: SHORT TERM EXPOSURE:
irritation, headache, drowsiness, symptoms of drunkenness, bluish
skin color, coma LONG TERM EXPOSURE: tingling sensation, liver
damage SKIN CONTACT: SHORT TERM EXPOSURE: irritation, rash LONG
TERM EXPOSURE: burns EYE CONTACT: SHORT TERM EXPOSURE: irritation
LONG TERM EXPOSURE: same as effects reported in short term exposure
INGESTION: SHORT TERM EXPOSURE: nausea, vomiting, stomach pain,
headache, symptoms of drunkenness, bluish skin color, coma LONG
TERM EXPOSURE: liver damage
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:82 F (28 C) (CC)
Autoignition Temp:1099 F (593 C)
Lower Limits:1.3%
Upper Limits:7.1%
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.

Neutralizing Agent:

Handling and Storage Precautions:Store and handle in accordance with
all current regulations and standards. Subject to storage
regulations: U.S. OSHA 29 CFR 1910.106. Grounding and bonding
required. Store with flammable liquids. Store outside or in a
detached building. Keep separated from incompatible substances.
Keep separated from incompatible substances.
Other Precautions:

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. Provide an
emergency eye wash fountain and quick drench shower in the
immediate work area.
Other Protective Equipment:Wear appropriate chemical resistant
clothing.
