Fire Fighting Instructions
Dike off area to prevent runoff and contamination of water
sources. Thermal decomposition products of this material
may be hazardous. These may include hydrogen chloride gas.
Isolate damage area and keep unauthorized personnel out.
Stop spill/release if it can be done with minimal risk.
Move undamaged containers from danger area if it can be done
with minimal risk. Water spray may be useful in minimizing
or dispersing vapors. Cool equipment exposed to fire with
water if it can be done with minimal risk.
Fire Fighting Equipment:
Wear protective clothing and self contained breathing
apparatus. Wear other appropriate equipment as conditions
warrant.
Hazardous Combustion Products:
Thermal decomposition products may be hazardous. These may
include hydrogen chloride. This material will vigorously
decompose, releasing carbon dioxide, if heated above 80掳C
(176掳F). The potential for tank rupture exists if material
is heated to decomposition. Closed containers exposed to
extreme heat can rupture due to pressure buildup. Dilute
material in contact with common metals can generate
hydrogen, which can form flammable mixtures with air.
