Carbon dioxide, dry chemical, or water fog. Water spray or foam may cause frothing.

SPECIFIC HAZARDS DURING FIRE FIGHTING : Hot product is a vapor explosion hazard indoors, outdoors, or in sewers. Vapors or gases may ignite at distant ignition sources and flash back. Most vapors are heavier than air and will spread along ground and collect in low or confined areas (drains, basements, tanks). Runoff may create fire or explosion hazard. Containers may rupture or explode if exposed to heat. Empty containers may retain product residue including flammable/explosive vapors. Product is not sensitive to mechanical impact or static discharge. For cooled product: Product may burn, but does not ignite readily.


Fire Fighting Instructions : This material will burn although it is not easily ignited. See Section 7 for proper handling and storage. For fires involving this material, evacuate area. Prevent runoff from fire control or dilution from entering streams, sewers, or drinking water supply. Firefighters should use standard protective equipment and in enclosed spaces, self-contained breathing apparatus (SCBA). Use water spray to cool fire exposed surfaces and to protect personnel. Combustion Products: Highly dependent on combustion conditions. A complex mixture of airborne solids, liquids, smoke, incomplete combustion products and gases including sulfur oxides and assorted oxides of carbon.
