Flash Point:61 F (16 C) (CC)
Autoignition Temp:516 F (269 C)
Lower Limits:1.0%
Upper Limits:5.9%
Extinguishing Media:alcohol resistant foam, carbon dioxide, regular dry
chemical, water Large fires: Use alcohol-resistant 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. 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. Avoid
inhalation of material ocombustion by-products. Stay upwind and
keep out of low areas. Water may be ineffective.
Unusual Fire/Explosion Hazard:Severe fire hazard. The vapor is heavier
than air. Vapors or gases may ignite at distant ignition sources
and flash back. Vapor/air mixtures are explosive.

Neutralizing Agent:

Handling and Storage Precautions:Store and handle in accordance with
all current regulations and standards. Subject to storage
regulations: U.S. OSHA 29 CFR 1910.106. Grounding and bonding
required. Keep separated from incompatible substances. May form
explosive peroxides. Store in a tightly closed container. Avoid
contact with light. Store in a cool, dry place. Monitor inhibitor
content. Do not evaporate or distill to dryness.
Other Precautions:

Respiratory Protection:Under conditions of frequent use or heavy
exposure, respiratory protection may be needed. Respiratory
protection is ranked in order from minimum to maximum. Consider
warning properties before use. Any supplied-air respirator with a
full facepiece that is operated in a pressure-demand or other
positive-pressure mode. Any self-contained breathing apparatus that
has a full facepiece and is operated in a pressure-demand or other
positive-pressure mode. 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 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.
