Question: 1 / 400

What does a Class K extinguisher use to suppress fires?

Water

A foam agent

A dry chemical agent

A wet chemical agent which cools and emulsifies cooking oils

A Class K extinguisher is specifically designed to suppress fires that involve cooking oils and fats. These types of fires are often associated with commercial kitchen environments where deep fryers and other cooking appliances are used. The wet chemical agent in a Class K extinguisher effectively cools the flames and reacts with the cooking oils to create an emulsification process. This not only helps in extinguishing the fire but also prevents the potential for re-ignition, which is a critical concern in cooking environments.

The use of a wet chemical specifically tailored for Class K fires makes this type of extinguisher crucial in addressing the unique properties of cooking oils, as traditional extinguishing agents might not be effective or safe. The ability of the wet chemical to form a barrier between the fuel and the oxygen is key to safely extinguishing these fires.
