What class of fire includes combustible liquids?

The classification of fires is based on the materials that are burning, and understanding these classes is crucial for effective fire safety and response. The correct classification for fires involving combustible liquids, such as gasoline, oil, and alcohol, is Class B.

Class B fires are specifically associated with flammable liquids and gases. These types of fires require extinguishing agents that can effectively suppress the vapor produced by the burning liquids and prevent re-ignition. Common extinguishing agents for Class B fires include foam, carbon dioxide, and dry chemicals.

Class A fires involve ordinary combustible materials like wood, paper, and cloth. Class C fires pertain to electrical equipment, where use of water-based extinguishing agents could pose a risk of electrocution. Class D fires involve combustible metals, which require specialized extinguishing techniques.

Recognizing the nature of the materials involved in a fire is essential for selecting the appropriate fire extinguisher and ensuring safety during fire emergencies.
