ASCP Diplomate in Laboratory Management (DLM) Practice Exam

Question: 1 / 400

What type of fire do Class C fires involve?

Fires involving flammable liquids

Fires that produce toxic smoke

Fires involving electrical equipment

Class C fires specifically involve electrical equipment. This classification is important because the methods used to extinguish electrical fires differ significantly from those used to combat fires caused by other materials. For example, water, a common extinguishing agent for many types of fires, is a conductor of electricity and could create additional hazards when used on electrical fires. Instead, appropriate fire suppression methods for Class C fires may include the use of non-conductive agents such as carbon dioxide (CO2) or dry chemical extinguishers designed for electrical fires.

Understanding class distinctions in fire types is crucial for safety protocols in laboratory and industrial environments, as it informs staff about the appropriate fire response strategies and helps prevent further risks associated with an incorrect extinguishing approach.
