Reports of Carcinogenicity:NTP:Yes IARC:Yes OSHA:No
Health Hazards Acute and Chronic:INHALATION: SHORT TERM EXPOSURE:
irritation, tearing, vomiting, diarrhea, difficulty breathing,
headache, drowsiness, symptoms of drunkenness LONG TERM EXPOSURE:
lung congestion, cancer SKIN CONTACT: SHORT TERM EXPOSURE:
irritation (possibly severe), blisters LONG TERM EXPOSURE: same as
effects reported in short term exposure EYE CONTACT: SHORT TERM
EXPOSURE: irritation (possibly severe) LONG TERM EXPOSURE: same as
effects reported in short term exposure INGESTION: SHORT TERM
EXPOSURE: no information on significant adverse effects LONG TERM
EXPOSURE: cancer
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 and activated charcoal slurry.

Flash Point:-35 F (-37 C) (CC)
Autoignition Temp:840 F (449 C)
Lower Limits:2.3%
Upper Limits:36%
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). Water may be ineffective.
Unusual Fire/Explosion Hazard:Moderate fire hazard. The vapor is
heavier than air. Vapors or gases may ignite at distant ignition
sources and flash back. Vapor/air mixtures are explosive above
flash point.

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. Protect from physical damage. Store outside or in a
detached building. Store with flammable liquids. Keep separated
from incompatible substances. Keep separated from incompatible
substances. Notify State Emergency Response Commission for storage
or use at amounts greater than or equal to the TPQ (U.S. EPA SARA
Section 302). SARA Section 303 requires facilities storing a
material with a TPQ to participate in local emergency response
planning (U.S. EPA 40 CFR 355.30).
Other Precautions:

Respiratory Protection:The following respirators and maximum use
concentrations are drawn from NIOSH and/or OSHA. At any detectable
concentration - Any self-contained breathing apparatus that has a
full facepiece and is operated in a pressure-demand or other
positive-pressure mode. 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. Escape - Any air-purifying respirator with a full facepiece
and a canister providing protection against this substance. 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 or process enclosure 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.
