Hazardous thermal decomposition products
Specific hazards arising from the chemical
Decomposition products may include the following materials: carbon dioxide
Flammable liquid and vapor. In a fire or if heated, a pressure increase will occur and the container may burst, with the risk of a subsequent
explosion. The vapor/gas is heavier than air and will spread along the ground. Vapors may accumulate in low or confined areas or travel a
considerable distance to a source of ignition and flash back. Runoff to sewer may create fire or explosion hazard. This material is harmful
to aquatic life with long lasting effects. Fire water contaminated with this material must be contained and prevented from being discharged
to any waterway, sewer or drain.
Fire-fighters should wear appropriate protective equipment and self-contained breathing apparatus (SCBA) with a full face-piece operated
in positive pressure mode.
