FLAMMABLE PROPERTIES
FLASH POINT: -156F, -104C
METHOD USED: Estimated
AUTOIGNITION TEMPERATURE: NA
FLAMMABILITY LIMITS
LFL: NA
UFL: NA
HAZARDOUS COMBUSTION PRODUCTS: During a fire, smoke may contain the original
material in addition to unidentified toxic and/or irritating compounds.
Hazardous combustion products may include but are not limited to: nitrogen
oxides, isocyanates, hydrogen cyanide, carbon monoxide, and carbon dioxide.
OTHER FLAMMABILITY INFORMATION: Product reacts with water. Reaction may
produce heat and/or gases. Reaction may be violent. Container may rupture
from gas generation in a fire situation. Violent steam generation or
eruption may occur upon application of direct water stream to hot liquids.
Dense smoke is produced when product burns. Spills of these organic liquids
on hot fibrous insulations may lead to lowering of the autoignition
temperatures possibly resulting in spontaneous combustion.
EXTINGUISHING MEDIA: Carbon dioxide, dry chemical, foam, water fog or fine
spray. Alcohol resistant foams (ATC type) are preferred if available.
General purpose synthetic foams (including AFFF) or protein foams may
function, but much less effectively. Do not use direct water stream. May
spread fire.
FIRE FIGHTING INSTRUCTIONS: Keep people away. Isolate fire area and deny
unnecessary entry. Stay upwind. Keep out of low areas where gases (fumes)
can accumulate. Water is not recommended but may be applied in very large
quantities as a fine spray when other extinguishing agents are not
available. Contain fire water run-off if possible. Do not use direct water
stream. May spread fire. Fight fire from protected location or safe
distance. Consider use of unmanned hose holder or monitor nozzles. Use
water spray to cool fire exposed containers and fire affected zone until
fire is out. Immediately withdraw all personnel from area in case of rising
sound from venting safety device or discoloration of the container. Move
container from fire area if this is possible without hazard.
PROTECTIVE EQUIPMENT FOR FIRE FIGHTERS: Wear positive-pressure self-
contained breathing apparatus (SCBA) and protective fire fighting clothing
(includes fire fighting helmet, coat, pants, boots, and gloves). Avoid
contact with this material during fire fighting operations. If contact is
likely, change to full chemical resistant clothing with SCBA. This will not
provide sufficient fire protection; consider fighting fire from a remote
location. For protective equipment in post-fire or non-fire clean-up
situations, refer to the relevant sections.
5. FIRE-FIGHTING MEASURES
PROTECT PEOPLE: Avoid any contact. Barricade area. Clear non-emergency
personnel from area. Keep upwind of spill. Ventilate area of leak or spill.
The area must be evacuated and reentered by persons equipped for
decontamination. Use appropriate safety equipment. Ventilate area of leak or
spill. If available, use foam to suppress vapors. For additional
information, refer to "Exposure Controls/Personal Protection", MSDS Section
8. See Section 10, Stability and Reactivity.
