Flash Point:flammable
Autoignition Temp:212 F (100 C)
Lower Limits:1%
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).
Unusual Fire/Explosion Hazard:Severe fire hazard. May ignite on
exposure to air. Vapor/air mixtures are explosive. Containers may
rupture or explode if exposed to heat.

Spill Release Procedures:Avoid heat, flames, sparks and other sources
of ignition. Stop leak if possible without personal risk. Reduce
vapors with water spray. Keep unnecessary people away, isolate
hazard area and deny entry. Remove sources of ignition. Ventilate
closed spaces before entering. Notify Local Emergency Planning
Committee and State Emergency Response Commission for release
greater than or equal to RQ (U.S. SARA Section 304). If release
occurs in the U.S. and is reportable under CERCLA Section 103,
notify the National Response Center at (800)424-8802 (USA) or
(202)426-2675 (USA).

Handling and Storage Precautions:Store and handle in accordance with
all current regulations and standards. Subject to storage
regulations: U.S. OSHA 29 CFR 1910.101. 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. 3 ppm Any
supplied-air respirator. 7.5 ppm Any supplied-air respirator. 15
ppm Any air-purifying respirator with a full facepiece and a
canister providing protection against this substance. Any
self-contained breathing apparatus with a full facepiece. Any
supplied-air respirator with a full facepiece. 50 ppm Any
supplied-air respirator operated in a pressure-demand or other
positive-pressure mode. 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. 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: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.
