Fraction By Weight: 100.0%

Reports of Carcinogenicity:NTP:No IARC:No OSHA:No
Health Hazards Acute and Chronic:INHALATION: SHORT TERM EXPOSURE:
irritation (possibly severe), difficulty breathing, lung congestion
LONG TERM EXPOSURE: same as effects reported in short term exposure
SKIN CONTACT: SHORT TERM EXPOSURE: burns LONG TERM EXPOSURE: same
as effects reported in short term exposure EYE CONTACT: SHORT TERM
EXPOSURE: irritation (possibly severe), blurred vision LONG TERM
EXPOSURE: same as effects reported in short term exposure
INGESTION: SHORT TERM EXPOSURE: burns, vomiting, digestive
disorders LONG TERM EXPOSURE: same as effects reported in short
term exposure
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: DO NOT induce vomiting.
Never make an unconscious person vomit or drink fluids. Give large
amounts of water or milk. 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 esophagoscopy. Avoid gastric lavage.

Flash Point:0 F (-18 C) (CC)
Autoignition Temp:756 F (402 C)
Lower Limits:2.8%
Upper Limits:14.4%
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. 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: 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: 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). Do not attempt to
extinguish fire unless flow of material can be stopped first. Flood
with fine water spray. Do not scatter spilled material with
high-pressure water streams. Cool containers with water spray until
well after the fire is out. Apply water from a protected location
or from a safe distance. Avoiinhalation of material or combustion
by-products. Stay upwind and keep out of low areas. Stop flow of
gas.
Unusual Fire/Explosion Hazard:Severe fire hazard. Moderate explosion
hazard. Vapor/air mixtures are explosive above flash point. The gas
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. Keep separated from
incompatible substances.
Other Precautions:

Respiratory Protection:The following respirators and maximum use
concentrations are drawn from NIOSH and/or OSHA. 250 ppm Any
supplied-air respirator. 500 ppm Any self-contained breathing
apparatus with a full facepiece. Any supplied-air respirator with a
full facepiece. 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 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.
