Hazardous combustion products: During a fire, smoke may contain the original material in addition
to combustion products of varying composition which may be toxic and/or irritating. Combustion
products may include and are not limited to: Nitrogen oxides. Isocyanates. Hydrogen chloride.
Carbon monoxide. Carbon dioxide. Hydrogen cyanide.
Unusual Fire and Explosion Hazards: Contains flammable propellant. Aerosol cans exposed to fire
can rupture and become flaming projectiles. Propellant release may result in a fireball. Vapors are
heavier than air and may travel a long distance and accumulate in low lying areas. Ignition and/or flash
back may occur. Dense smoke is produced when product burns.
Advice for firefighters
Fire Fighting Procedures: Keep people away. Isolate fire and deny unnecessary entry. Stay
upwind. Keep out of low areas where gases (fumes) can accumulate. Water may not be effective in
extinguishing fire. Do not use direct water stream. May spread fire. Fight fire from protected location
or safe distance. Consider the use of unmanned hose holders or monitor nozzles. Eliminate ignition
sources. Move container from fire area if this is possible without hazard. Use water spray to cool fire-
exposed containers and fire-affected zone until fire is out.
Special protective equipment for firefighters: Wear positive-pressure self-contained breathing
apparatus (SCBA) and protective fire fighting clothing (includes fire fighting helmet, coat, trousers,
boots, and gloves). Avoid contact with this material during fire fighting operations. If contact is likely,
change to full chemical resistant fire fighting clothing with self-contained breathing apparatus. If this is
not available, wear full chemical resistant clothing with self-contained breathing apparatus and fight
fire from a remote location. For protective equipment in post-fire or non-fire clean-up situations, refer
to the relevant sections.
6. ACCIDENTAL RELEASE MEASURES
Personal precautions, protective equipment and emergency procedures: Evacuate area. Only
trained and properly protected personnel must be involved in clean-up operations. Keep personnel
out of low areas. Keep personnel out of confined or poorly ventilated areas. Keep upwind of spill.
Ventilate area of leak or spill. No smoking in area. For large spills, warn public of downwind explosion
hazard. Check area with combustible gas detector before reentering area. Ground and bond all
containers and handling equipment. Eliminate all sources of ignition in vicinity of spill or released
vapor to avoid fire or explosion. Vapor explosion hazard. Keep out of sewers. See Section 10 for
more specific information. Use appropriate safety equipment. For additional information, refer to
Section 8, Exposure Controls and Personal Protection. Confined space entry procedures must be
followed before entering the area. Refer to section 7, Handling, for additional precautionary measures.
Environmental precautions: Prevent from entering into soil, ditches, sewers, waterways and/or
groundwater. See Section 12, Ecological Information. Spills or discharge to natural waterways is likely
to kill aquatic organisms.
Methods and materials for containment and cleaning up: Contain spilled material if possible.
Ground and bond all containers and handling equipment. Isolate area until gas has dispersed. Use
non-sparking tools in cleanup operations. Eliminate all sources of ignition in vicinity of spill or released
vapor to avoid fire or explosion. Check area with combustible gas detector before reentering area.
Ground and bond all containers and handling equipment. Collect in suitable and properly labeled
containers. Absorb with materials such as: Clay. Dirt. Milsorb®. Sand. Sawdust. Vermiculite. See
Section 10 for more specific information. See Section 13, Disposal Considerations, for additional
information.
