SECTION 5: Fire Fighting Measures
As in any fire, wear a self-contained breathing apparatus in pressure-
General Information:
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. Vapors may be heavier than air. They can
spread along the ground and collect in low or confined areas. Cool containers
with flooding quantities of water.
Small fire use water spray, dry chemical, carbon dioxide. Large fire use water
Extinguishing Media:
spray, water fog dry chemical, carbon dioxide, or alcohol resistant foam.
DO NOT USE SOLID WATER STREAM. Water spray may spread fire.
