š Key Concepts
ā¢ The fire classes are based on the type of fuel that is burning, not the location of the fire
ā¢ Remember what materials are involved with Class A, B, C, and D fires (ordinary combustibles, flammable liquids, energized electrical equipment, and combustible metals)
ā¢ An electrical generator involves both electrical components and sometimes fuel/oil nearby, but focus on what the question is really asking about
š Think About
ā¢ Ask yourself: In this question, are they emphasizing the electrical/energized equipment or the fuel source around it?
ā¢ Which fire class is specifically defined for energized electrical equipment such as panels, switchboards, and generators?
ā¢ Could this same fire class apply to things like live wiring, circuit breakers, and energized motors?

Before You Answer
ā¢ Review the standard definitions of Class A, B, C, and D fires and match each to its common fuel type
ā¢ Confirm which class is used for energized electrical equipment and make sure you distinguish it from flammable liquids
ā¢ Before choosing, double-check that you are not confusing the fire class for the fuel (like diesel) with the class for the energized electrical source itself
