Health Hazards Acute and Chronic:INHALATION: SHORT TERM EXPOSURE:
irritation (possibly severe), difficulty breathing, symptoms of
drunkenness, dizziness, bluish skin color, lung congestion LONG
TERM EXPOSURE: digestive disorders SKIN CONTACT: SHORT TERM
EXPOSURE: irritation (possibly severe), absorption may occur LONG
TERM EXPOSURE: headache, drowsiness, symptoms of drunkenness,
blurred vision, lung congestion EYE CONTACT: SHORT TERM EXPOSURE:
irritation (possibly severe), blindness LONG TERM EXPOSURE: same as
effects reported in short term exposure INGESTION: SHORT TERM
EXPOSURE: burns, nausea, vomiting, difficulty breathing,
drowsiness, symptoms of drunkenness, kidney damage, coma LONG TERM
EXPOSURE: reproductive effects
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
flush eyes with plenty of water for at least 15 minutes. Then get
immediate medical attention. INGESTION: Contact local poison
control center or physician immediately. Never make an unconscious
person vomit or drink fluids. 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. For ingestion,
consider gastric lavage.

Flash Point:34 F (1 C) (SCC)
Extinguishing Media: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. Do not get water inside container. Cool
containers with water spray until well after the fire is out. Stay
away from the ends of tanks. 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. Cool containers with water spray
until well after the fire is out. Apply water from a protected
location or from a safe distance. Do not get water directly on
material. Large fires: Flood with fine water spray. Reduce vapors
with water spray. Avoid inhalation of material or combustion
by-products. Stay upwind and keep out of low areas.
Unusual Fire/Explosion Hazard:Severe fire hazard. The vapor is heavier
than air. Vapors or gases may ignite at distant ignition sources
and flash back. May ignite if exposed to shock, friction or
heating. Avoid friction and static electricity.

Spill Release Procedures:Avoid heat, flames, sparks and other sources
of ignition. Do not touch spilled material. Stop leak if possible
without personal risk. Reduce vapors with water spray. Do not get
water inside container. 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. Subject to storage
regulations: U.S. OSHA 29 CFR 1910.106. Grounding and bonding
required. 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. 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.
