Multiple Choice

Which fire class is extinguished with CO2?

Explanation:
CO2 extinguishers are chosen for electrical fires because CO2 is nonconductive and leaves no residue that could affect energized equipment, while smothering the flame by displacing the surrounding oxygen. In this question, the fire class associated with using CO2 is the Delta class, so Delta is the best choice. The other fire classes involve ordinary combustibles, flammable liquids, or metals and require different extinguishing agents (for example, water or foam, dry chemical, or specialized powders), so CO2 wouldn’t be appropriate for them.
