G2 Gas Fitter Practice Exam

Select the type of fire extinguisher used to fight fires involving energized electrical equipment.

1. Type A

2. Type B

3. Type C

4. Type D

The correct answer is: Type C

The type of fire extinguisher that is specifically designed to combat fires involving energized electrical equipment is classified as Type C. This classification is crucial because Type C extinguishers utilize non-conductive agents, such as carbon dioxide (CO2) or dry chemical agents, to effectively put out electrical fires without posing a risk of electric shock or further ignition. When dealing with situations involving energized electrical equipment, using the wrong type of extinguisher, such as those designed for other classes of fires, could lead to severe consequences, including personal injury or making the fire worse. Type A extinguishers are meant for ordinary combustible materials, Type B extinguishers are for flammable liquids and gases, and Type D extinguishers are specialized for combustible metals. Each of these types addresses different fire scenarios and would not be appropriate for electrical fires. Therefore, selecting Type C is essential for safety and effective fire management in environments with energized electrical equipment.
