Fire Fighting MeasuresBack to Contents
【Flash Point】

140
【Fire Fighting】

Wear a self-contained breathing apparatus in pressure-demand, MSHA/NIOSH (approved or equivalent), and full protective gear. During a fire, irritating and highly toxic gases may be generated by thermal decomposition or combustion. Use water spray to keep fire-exposed containers cool. Water may be ineffective. Material is lighter than water and a fire may be spread by the use of water. Extinguishing media: Water may be ineffective. Cool containers with flooding quantities of water until well after fire is out. In case of fire use water spray, dry chemical, carbon dioxide, or appropriate foam.
【Fire Potential】

Combustible material: may burn but does not ignite readily.
Accidental Release MeasuresBack to Contents
【Small spills/leaks】

Vacuum or sweep up material and place into a suitable disposal container. Avoid runoff into storm sewers and ditches which lead to waterways. Clean up spills immediately, using the appropriate protective equipment. Remove all sources of ignition. Provide ventilation.
Stability and ReactivityBack to Contents
【Incompatibilities】

Oxidizing agents.
【Stability】

Stable at room temperature in closed containers under normal storage and handling conditions.
【Decomposition】

Carbon monoxide, irritating and toxic fumes and gases, carbon dioxide.
【Combustion Products】

Fire may produce irritating, corrosive and/or toxic gases.
