Question 715 Deck Safety

The correct answer is D) electrical insulation. A Class C fire is defined as a fire involving energized electrical equipment. Electrical insulation, which is used to cover wires and other electrical components, is the primary fuel source for a Class C fire. Fires involving energized electrical equipment require a different extinguishing agent than those used for Class A (ordinary combustible materials) or Class B (flammable liquids and gases) fires. The other answer choices are incorrect because they do not match the definition of a Class C fire. Fuel oil (A), celluloid (B), and wood (C) are not the primary fuel sources for an electrical fire.
