Fire extinguishers, dangers with sodium fires

In the event of a large spill of liquid fluorine, the contaminated area can be neutralized with sodium carbonate. The dry powder can be sprayed on the spill area from a fluidized system similar in principle to that of dry chemical fire extinguishers. If major spills occur in areas where the formation of hydrofluoric acid liquid and vapor pose no undue danger, water in the form of a fine mist or fog is recommended. 

CARBONIC ACID, BARIUM SALT (513-77-9) BaCOj Noncombustible solid. The aqueous solution is basic. Dissolves in most acids except sulfuric acid with release of CO2 gas. This could be dangerous in a confined space. Incompatible with finely divided alxuninum bromine trifluoride fluorine, 2-furanpercarboxylic acid magnesium, oxidizers, sodium azide silicon strong alkalis. Decomposes above 2372°F/1300°C, releasing COj and soluble barium salts including barium oxide. On small fires, use dry chemical powder (such as Purple-K-Powder), foam, or CO2 extinguishers.
