Which type of extinguisher is used to fight fires involving flammable or combustible vapor?

Type A
Type B
Type C
Type D

The correct answer is: Type B

The choice of Type B extinguisher is correct because it is specifically designed to combat fires that involve flammable liquids and combustible vapors. These types of fires can occur with substances such as gasoline, oil, solvents, and similar materials. Type B extinguishers contain dry chemicals, foam, or carbon dioxide, which are effective in smothering flames and preventing the re-ignition of flammable vapors. Regarding the other types of extinguishers, Type A is suitable for ordinary combustibles like wood or paper, while Type C is intended for electrical fires, and Type D is used for combustible metals. Therefore, they would not be effective or appropriate in addressing fires associated with flammable or combustible vapors, which is why Type B is the unequivocal choice in this scenario.
