Section 5 - Fire Fighting Measures
Flash Point: Not applicable Method Used: Not determined
Upper Flammable Limit (UFL): Not applicable Lower Flammable Limit (LFL): Not applicable
Auto Ignition: Not determined Flammability Classification: Not determined
Rate of Burning: Not determined
General Fire Hazards
Polyester can burn if exposed to flame. Molten polymer generates small amounts of volatile degradation products (off-gases),
one of which is acetaldehyde. Acetaldehyde vapors form explosive mixtures with air that can spontaneously ignite (auto-
ignite) at temperatures above 175潞C (347潞F). Combustion products will be comprised of compounds of carbon, hydrogen, and
oxygen. The exact composition will depend on the conditions of combustion.
Extinguishing Media
No special procedures are expected to be necessary for this product. Normal fire fighting procedures should be followed to
avoid inhalation of smoke and gases.
Fire Fighting Equipment/Instructions
Firefighters should wear full protective clothing including self contained breathing apparatus.
