Overhead Crane Practice Test 2025 – Complete Prep Guide

The requirement for using a Type C fire extinguisher for overhead cranes, as per ASME B30.2, relates specifically to the kinds of hazards present in the environment where these cranes operate. Type C extinguishers are designed to combat electrical fires, which can be a significant risk in workplaces with overhead cranes due to the electrical components used for their operation.

Overhead cranes often utilize electric motors and other electrical equipment, making it crucial to have a fire extinguisher that is effective against potential electrical fires. This ensures that in the event of an electrical fire caused by malfunctioning equipment, there is an appropriate means to address it safely without putting the operator or others in the vicinity at risk.

Type A extinguishers are for ordinary combustibles, Type B extinguishers are for flammable liquids, and Type D extinguishers are for combustible metals, which are less relevant in the context of operating an overhead crane. Therefore, selecting a Type C extinguisher adheres to safety regulations necessary for environments where electrical equipment is used, making it the correct choice for overhead crane operations.
