🔍 Key Concepts

• The fire classes are based on the type of fuel that is burning, not the location of the fire • Remember what materials are involved with Class A, B, C, and D fires (ordinary combustibles, flammable liquids, energized electrical equipment, and combustible metals) • An electrical generator involves both electrical components and sometimes fuel/oil nearby, but focus on what the question is really asking about

💭 Think About

• Ask yourself: In this question, are they emphasizing the electrical/energized equipment or the fuel source around it? • Which fire class is specifically defined for energized electrical equipment such as panels, switchboards, and generators? • Could this same fire class apply to things like live wiring, circuit breakers, and energized motors?

✅ Before You Answer

• Review the standard definitions of Class A, B, C, and D fires and match each to its common fuel type • Confirm which class is used for energized electrical equipment and make sure you distinguish it from flammable liquids • 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
