Section IV 鈥? Fire and Explosion Hazard Data
Flash Point (Method Used): Not applicable Flammable Limits: LEL (Lower Explosive Limit) - N/A
UEL (Upper Explosive Limit) - N/A
Extinguishing Media: Suitable extinguishing agents. CO2, extinguishing powder, or water spray.
Special Fire Fighting Procedures: Fight larger fires with water or alcohol resistant foam. Firefighters should wear
protective equipment and self-contained breathing apparatus. As with most organic solids, fire is possible at elevated
temperatures or by contact with an ignition source.
Unusual Fire and Explosion Hazards: During heating or in case of fire, poisonous gases are produced. Fine dust
dispersed in air in sufficient concentrations, and in the presence of an ignition source is a potential dust explosion hazard.
May explode if mixed with oxidizers, such as potassium nitrate, potassium nitrite, and potassium chlorate.
