What type of materials does Class K fire involve?

Class K fires involve materials that consist of vegetable and animal oils, greases, and fats. These types of fires are commonly associated with cooking environments, particularly in commercial kitchens where large quantities of cooking oils are used. The combustion of these oils can produce intense heat and can spread rapidly if not addressed properly.

Class K fire extinguishers are specifically designed to handle these types of fires, as traditional extinguishing agents might not be effective and can even exacerbate the situation. For instance, using water on a Class K fire can cause the burning oil to splatter, potentially spreading the fire further. Understanding the nature of Class K fires is crucial for fire guards and safety personnel, as it emphasizes the importance of using the appropriate methods and materials for fire suppression in cooking areas.
