Alcohol-resisting AFFF foam

Class of fire Extinguisher type Water Alcohol-resistant AFFF foam Wet chemical Vaporizing liquid NAFP 3 - commercial use only Ciubon oxide Dry chemical powder AB(E) and B(E) types... 

Fluoroprotein and alcohol resistant type AFFF concentrates are suitable for seal protection of open top floating roof tanks. Foam may be applied from fixed chambers in an "over-the-top" fashion or by discharge from "foam chambers" located at the top of the tank shell allowing the foam to run down the inside wall of the tank shell onto the seal area. Subsurface foam on floating tanks is generally not recommended as a sunken roof would block the foam distribution. Typical protection is shown in Table 7-10. 

AFFF) A fire extinguishing foam based on blended hydrocarbon and fluorocarbon surfactants a rapidly spreading foam used on hydrocarbon fires. See also Fluor-oprotein Foam, Film Forming Fluoroprotein Foam, Alcohol Resisting Aqueous Film Forming Foam. 

For chlorosilanes, do not use water use AFFF alcohol-resistant medium expansion foam. 

For chlorosilanes, use AFFF alcohol-resistant medium expansion foam do not use dry chemicals, soda ash, or lime on chlorosilane fires as they may release large quantities of hydrogen gas which may explode. 

ACETILUM ACIDILATUM (50-78-2) C9Hg04 Combustible solid. An organic acid. Powder or dust forms explosive mixture with air (flash point 482°F/250°C). Reacts with strong oxidizers, strong acids, strong bases. Contact with alkali hydroxides or carbonates may cause decomposition. Incompatible with acetanilide, acetaminophen, some alcohols, aliphatic amines alkanolamines, alkylene oxides amidopyrine, amines, ammonia, caustics, epichlorohydrin, hexamine, iron salts isocyanates, phenozone, phenobarbital sodium potassium iodide quinine salts sodium iodide stearates. Slowly hydrolyzes in moist air. On small fires, use AFFF, alcohol-resistant foam, dry chemical powder, or CO2 extinguishers.
