Question 712 Deck Safety

The correct answer is C) Class C. According to the US Coast Guard regulations for firefighting, a fire in a transformer terminal would be classified as a Class C fire. Class C fires involve energized electrical equipment, and the proper extinguishing agent for this type of fire is a non-conductive extinguishing agent, such as a carbon dioxide (CO2) or dry chemical extinguisher. This is because water or other conductive agents could potentially conduct electricity and create an additional hazard. The other answer choices are incorrect because Class A fires involve ordinary combustible materials, Class B fires involve flammable liquids or gases, and Class D fires involve combustible metals, none of which accurately describe a fire in a transformer terminal.
