5. FIRE FIGHTING MEASURES

EXTINGUISHING MEDIA: ………………………………………………………… SUITABLE: Foam, carbon dioxide (CO2), dry chemical. NON-SUITABLE:
Direct, high-pressure water stream.

FIRE AND EXPLOSION HAZARDS: ………………………………………….. During a fire, smoke may contain the original materials in addition to
combustion products of varying composition which may be toxic and/or irritating. Combustion products may include, but are not limited to: oxides
of nitrogen, carbon monoxide, carbon dioxide, volatile amines, ammonia, nitric acid, aldehydes, nitrosamines. When mixed with sawdust, wood
chips, or other cellulosic material, spontaneous combustion can occur under certain conditions. Heat is generated as the air oxidizes the amine. If
the heat is not dissipated quickly enough, it can ignite the sawdust.

SPECIAL FIRE FIGHTING PROCEDURES: ………………………………… Use full-body protective gear and a self-contained breathing apparatus.
Use of water may generate toxic aqueous solutions. Do not allow water run-off from fighting fire to enter drains or other water courses.

6. ACCIDENTAL RELEASE MEASURES

EMERGENCY PROCEDURES : …………………………………………………. Keep unnecessary and unprotected personnel from entering area. Use
appropriate safety and personal protective equipment as indicated in Section 8.

MITIGATION AND CLEAN UP PROCEDURES: …………………………… Stop leak without additional risk. Isolate area. Dike and absorb with inert
material (e.g., sand) and collect in a suitable, closed container. Do not use sawdust, wood chips or other cellulosic materials to absorb the spill, as
the possibility for spontaneous combustion exists. Warm, soapy water may be used to clean residual.

ENVIRONMENTAL PRECAUTIONS: ………………………………………….. Prevent from entering into soil, ditches, sewers, waterways and
groundwater. See Section 12 for environmental impact information.

7. HANDLING AND STORAGE

SECTION 5: Firefighting measures

Extinguishing media
Suitable extinguishing media : Foam. Carbon dioxide. Dry chemical.
Unsuitable extinguishing media : Do not use a heavy water stream.

Special hazards arising from the substance or mixture
Fire hazard : Products of combustion may include, and are not limited to: oxides of carbon, nitrogen oxides,
amines, ammonia, nitric acid, nitrosamines. When mixed with sawdust, wood chips, or other
cellulosic material, spontaneous combustion can occur under certain conditions. Heat is
generated as the air oxidizes the amine. If the heat is not dissipated quickly enough, it can
ignite the sawdust.
Reactivity : No dangerous reaction known under conditions of normal use.

Advice for firefighters
