What type of materials do Class K fires involve?

Class K fires specifically involve combustible cooking oils and fats, which are commonly found in commercial kitchens and cooking environments. This classification is crucial for first responders and firefighters to understand, as these types of fires require special extinguishing agents that can effectively cool and suppress the flames without spreading the fire further. Class K extinguishers, typically using a wet chemical agent, are designed to handle the unique characteristics of burning oils, which can reach high temperatures and may reignite if not properly extinguished. This knowledge underscores the importance of proper fire safety procedures in cooking facilities and ensures effective response to kitchen fires, thereby safeguarding lives and property.
