Fraction By Weight: >99.5%

Reports of Carcinogenicity:NTP:No IARC:No OSHA:No
Health Hazards Acute and Chronic:INHALATION: SHORT TERM EXPOSURE:
nausea, vomiting, diarrhea, headache, drowsiness, symptoms of
drunkenness, visual disturbances, bluish skin color, lung
congestion, nerve damage, paralysis, convulsions, coma LONG TERM
EXPOSURE: fainting, blurred vision SKIN CONTACT: SHORT TERM
EXPOSURE: irritation, blisters, symptoms of drunkenness, nerve
damage LONG TERM EXPOSURE: same as effects reported in long term
inhalation EYE CONTACT: SHORT TERM EXPOSURE: frostbite LONG TERM
EXPOSURE: no information is available INGESTION: SHORT TERM
EXPOSURE: frostbite LONG TERM EXPOSURE: no information is available
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:
If frostbite or freezing occur, immediately flush with plenty of
lukewarm water (105-115 F; 41-46 C). DO NOT USE HOT WATER. If warm
water is not available, gently wrap affected parts in blankets. Get
immediate medical attention. EYE CONTACT: Wash eyes immediately
with large amounts of water, occasionally lifting upper and lower
lids, until no evidence of chemical remains. Get medical attention
immediately. INGESTION: Never make an unconscious person vomit or
drink fluids. Give large amounts of water. DO NOT induce vomiting.
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 inhalation,
consider oxygen.

Flash Point:<32.0 F (<0 C) (CC)
Autoignition Temp:1170 F (632 C)
Lower Limits:8.1%
Upper Limits:17.4%
Extinguishing Media:Let burn unless leak can be stopped immediately.
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). Stop flow of gas.
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. Gas/air mixtures are explosive.

Neutralizing Agent:

Handling and Storage Precautions:Store and handle in accordance with
all current regulations and standards. Protect from physical
damage. Store in a cool, dry place. Store in a well-ventilated
area. Avoid heat, flames, sparks and other sources of ignition.
Store outside or in a detached building. Subject to storage
regulations: U.S. OSHA 29 CFR 1910.106. Grounding and bonding
required. Keep separated from incompatible substances.
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 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 insulated 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.
