Health Hazards Acute and Chronic:INHALATION: SHORT TERM EXPOSURE:
garlic odor, nausea, vomiting, stomach pain, chest pain, difficulty
breathing, headache, dizziness, disorientation, lung congestion,
blood disorders, liver damage, nerve damage, effects on the brain,
coma, death LONG TERM EXPOSURE: same as effects reported in short
term exposure SKIN CONTACT: SHORT TERM EXPOSURE: frostbite LONG
TERM EXPOSURE: no information is available EYE CONTACT: SHORT TERM
EXPOSURE: frostbite LONG TERM EXPOSURE: no information is available
INGESTION: SHORT TERM EXPOSURE: no information on significant
adverse effects 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: Contact with liquid:
Immediately flush eyes with plenty of water for at least 15
minutes. Then get immediate medical attention. INGESTION: If a
large amount is swallowed, get medical attention. NOTE TO
PHYSICIAN: For inhalation, consider oxygen.

Lower Limits:4.5%
Upper Limits:100%
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). Do not attempt to extinguish fire unless flow of
material can be stopped first. Flood with fine water spray. Cool
containers with water. Apply water from a protected location or
from a safe distance. Avoid inhalation of material or combustion
by-products. Stay upwind and keep out of low areas.
Unusual Fire/Explosion Hazard:Severe fire hazard. Moderate explosion
hazard. The gas 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. 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. 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: Wear appropriate chemical
resistant clothing. For the liquid: Wear appropriate protective,
cold insulating clothing.
