| Special Notes |

FIRE HAZARD: Ignition temperature >400° C (750° F).
Thermal decomposition will generate hydrogen fluoride, fluorinated hydrocarbons, carbon monoxide and carbonyl fluoride. In the event of fire, fire fighters must wear self-contained breathing apparatus and a protective suit. Extinguish with water, foam, carbon dioxide or dry chemical. Neutralise any refuse from a fire involving perfluoroelastomer with calcium hydroxide solution and wear Neoprene ® gloves when handling. |
