Question: 1 / 400

What type of equipment does a Class Charlie fire involve?

Wooden structures

Energized electrical equipment

A Class Charlie fire specifically involves energized electrical equipment. This type of fire occurs when electrical systems or components malfunction, catch fire, or short-circuit. Understanding this classification is crucial for proper fire response, as it dictates the type of fire extinguisher and methods to use for safe suppression.

Using water, for example, is dangerous and can conduct electricity, potentially leading to injury or further complications in extinguishing the fire. Instead, specialized extinguishing agents, such as dry chemical extinguishers or carbon dioxide extinguishers, are required to safely combat this type of fire without risking electrocution or additional hazards. This knowledge is essential for anyone who might encounter electrical fires in their duties, especially in a maritime context where electrical equipment is prevalent.
