Which fire class involves cooking oils and fats?

The classification of fires is based on the materials that fuel them. Cooking oils and fats are categorized under Class B fires, which specifically involve flammable liquids and gases.

When ignited, cooking oils and fats can create intense fires that require particular methods for extinguishment, as using water may cause the fire to spread due to the oil's buoyancy. Instead, Class B fires typically require foam, dry chemical powders, or carbon dioxide extinguishers that are effective on flammable liquids.

Understanding this classification is crucial for effective fire prevention and safety measures, especially in environments such as kitchens where oils and fats are prevalent.
