What type of fire is associated with Class K fire classification?

1. Combustible metals

2. Electrical equipment

3. Flammable liquids

4. Cooking oil and grease

The correct answer is: Cooking oil and grease

Class K fire classifications specifically relate to fires that involve cooking oils and greases, particularly in commercial kitchens. These types of substances have unique burning characteristics and require specific extinguishing agents to handle safely and effectively. Cooking oils and grease are often used in deep fryers and other cooking equipment, and when ignited, they can produce extremely high temperatures and spread rapidly, making them particularly hazardous. The appropriate fire suppression method for a Class K fire is typically a wet chemical fire extinguisher designed to create a barrier between the oxygen and the fuel, effectively cooling the fire and preventing re-ignition. Understanding the nature of Class K fires is vital for safety professionals, particularly in environments where cooking occurs, as it emphasizes the need for proper training and equipment to combat these specific fire hazards.
