Abstract
Aqueous film forming form (AFFF), carbon dioxide, Halon 1211, and water have been applied to burning sonobuoys containing lithium-sulfur dioxide. No chemical reactions were observed between the fire-extinguishing materials and the lithium of the batteries. Water-reactive lithium (and aluminum) compounds that could release large quantities of explosive acetylene, hydrogen, and methane were found in the incinerated batteries. The nature and amount of gas formed by the reactions with water indicates that most of the lithium remains inside a battery during a fire. The batteries were observed to vent sulfur dioxide as late as an hour after the initiation of the fire.
