Class K fires primarily involve which of the following?

Class K fires specifically refer to fires that occur due to cooking oils and fats, which are frequently found in commercial kitchens and cooking environments. These fires are distinguished by the types of materials burning, which often include oils like vegetable oil, animal fats, and other substances used in food preparation.

The suppression methods for Class K fires differ from those used for other classes of fires because water does not effectively extinguish them; in fact, it can spread the fire further. Instead, specialized extinguishing agents, such as wet chemical extinguishers, are designed to cool the oil and create a barrier between the fuel and the oxygen, helping to extinguish the flames effectively.

Understanding the unique characteristics and appropriate response methods for Class K fires is crucial for anyone involved in fire safety, particularly in settings such as restaurants or catering services where these materials are prevalent.
