Health Hazards Acute and Chronic:INHALATION: SHORT TERM EXPOSURE:
irritation, nausea, headache, drowsiness, symptoms of drunkenness
LONG TERM EXPOSURE: digestive disorders, kidney damage, liver
enlargement, reproductive effects, cancer SKIN CONTACT: SHORT TERM
EXPOSURE: blisters, frostbite LONG TERM EXPOSURE: no information on
significant adverse effects EYE CONTACT: SHORT TERM EXPOSURE:
irritation, blurred vision LONG TERM EXPOSURE: no information on
significant adverse effects INGESTION: SHORT TERM EXPOSURE:
frostbite LONG TERM EXPOSURE: no information on significant adverse
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:
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: If a large amount is swallowed, get medical
attention. NOTE TO PHYSICIAN: For inhalation, consider oxygen.

Flash Point:-105 F (-76 C)
Autoignition Temp:788 F (420 C)
Lower Limits:2.0%
Upper Limits:11.5%
Extinguishing Media:carbon dioxide, regular dry chemical 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. 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: Stop leak if possible without personal risk. Let burn unless
leak can be stopped immediately. For smaller tanks or cylinders,
extinguish and isolate from other flammables. Evacuation radius:
800 meters (1/2 mile). Stop flow of gas.
Unusual Fire/Explosion Hazard:Severe fire hazard. Vapor/air mixtures
are explosive. 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. Grounding and bonding
required. Store outside or in a detached building. Secure to
prevent tipping. Store in a cool, dry place. Store in a
well-ventilated area. Avoid heat, flames, sparks and other sources
of ignition. Subject to storage regulations: U.S. OSHA 29 CFR
1910.101. See original container for storage recommendations. Keep
separated from incompatible substances.
Other Precautions:

Respiratory Protection:The following respirators and maximum use
concentrations are drawn from NIOSH and/or OSHA. 5 ppm Any
air-purifying respirator with a full facepiece and a canister
providing protection against this substance. 10 ppm Any
air-purifying respirator with a full facepiece and a canister
providing protection against this substance. 25 ppm Any
air-purifying respirator with a full facepiece and a canister
providing protection against this substance. Any powered,
air-purifying respirator with a full facepiece and cartridge(s)
providing protection against this substance. Any supplied-air
respirator operated in a continuous-flow mode. 50 ppm Any
air-purifying respirator with a full facepiece and a canister
providing protection against this substance. Any powered,
air-purifying respirator with a full facepiece and cartridge(s)
providing protection against this substance. 1000 ppm 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 air-purifying respirator with a full
facepiece and a canister providing protection against this
substance. For Unknown Concentrations or Immediately Dangerous to
Life or Health - 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 self-contained breathing apparatus that has a
full facepiece and is operated in a pressure-demand or other
positive-pressure mode. Any air-purifying respirator with a full
facepiece and a canister providing protection against this
substance. 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:Ventilation equipment should be explosion-resistant if
explosive concentrations of material are present. Provide local
exhaust or process enclosure ventilation system. Ensure compliance
with applicable exposure limits.
Protective Gloves:Wear insulated gloves.
Eye Protection:For the gas: Eye protection not required, but
recommended. For the liquid: Wear splash resistant safety goggles.
Contact lenses should not be worn. Provide an emergency eye wash
fountain and quick drench shower in the immediate work area.
Other Protective Equipment:For the gas: Protective clothing is not
required. For the liquid: Wear appropriate protective, cold
insulating clothing.
