L'accumulation du gaz continuant à s'échapper peut provoquer une explosion. Masses of combustible metals do not usually represent great fire risks because heat is conducted away from hot spots so efficiently that the heat of combustion cannot be maintained. Class A fire extinguishers are used for ordinary combustibles, such as paper, wood, cloth, and some types of plastic.
