Officer FMF Consolidated 101-119 Practice Test

Which class is not part of the standard fire classes?

Class E Class B Class A Class C

Correct Answer:

Class E

Explanation:

Understanding fire class labels helps you match the extinguisher and approach to the fire type. In standard classifications used today, the common categories are Class A for ordinary combustibles, Class B for flammable liquids, Class C for energized electrical equipment, Class D for metals, and Class K for cooking oils. Class E isn’t part of this standard set. Some older or alternative schemes used E to denote electrical fires, but the current widely adopted practice uses Class C for electrical fires. So the label that isn’t part of the standard lineup is Class E.
