Reports of Carcinogenicity:NTP:No IARC:No OSHA:No
Health Hazards Acute and Chronic:INHALATION: SHORT TERM EXPOSURE: burns
LONG TERM EXPOSURE: same as effects reported in short term exposure
SKIN CONTACT: SHORT TERM EXPOSURE: burns, absorption may occur,
nausea, headache LONG TERM EXPOSURE: same as effects reported in
short term exposure EYE CONTACT: SHORT TERM EXPOSURE: burns,

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: If swallowed, drink plenty
of water, do NOT induce vomiting. Get immediate medical attention.
NOTE TO PHYSICIAN: For inhalation, consider oxygen. Avoid gastric
lavage or emesis.

Flash Point:10 F (-12 C) (CC)
Autoignition Temp:374 F (190 C)
Lower Limits:2.0%
Upper Limits:11.6%
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. 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. Stop flow of gas.
Unusual Fire/Explosion Hazard:Severe fire hazard. Moderate explosion
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. Containers may rupture or explode if
exposed to heat.

Neutralizing Agent:

Handling and Storage Precautions:Store and handle in accordance with
all current regulations and standards. Store below 52 C. Store in a
cool, dry place. Store in a well-ventilated area. Store outside or
in a detached building. Avoid contact with water or moisture.
Protect from physical damage. Subject to storage regulations: U.S.
OSHA 29 CFR 1910.101. Keep separated from incompatible substances.

ppm (36 mg/m3) NIOSH recommended STEL 1 ppm AIHA recommended TWA
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 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.
