Class K fires are primarily related to what type of materials?

Class K fires are specifically associated with cooking oils and greases, particularly those found in commercial kitchens. These fires typically involve vegetable oils, animal fats, or other types of cooking substances that are used at high temperatures.

When subjected to high heat, these oils can ignite and produce intense flames that are difficult to extinguish with water. Instead, Class K fires require specific extinguishing agents designed for such materials, often involving special wet chemical fire extinguishers that work by cooling the oil and creating a barrier to the oxygen.

Understanding the characteristics of Class K fires is crucial for fire safety, especially in environments where cooking is prevalent, to ensure the proper firefighting equipment is readily available and used effectively.
