Which class of fire involves ordinary solid combustible materials?

Class A fires involve ordinary solid combustible materials, such as wood, paper, cloth, rubber, and some plastics. These materials are characterized by their ability to ignite and burn when exposed to heat sources. The combustion process of these materials typically produces ash, which is a distinctive feature of Class A fires.

Firefighters use water or other types of extinguishing agents that can cool and soak these materials to effectively suppress Class A fires. Understanding this classification is essential for choosing the right method and materials for fire suppression. It’s important for firefighters to quickly identify the class of fire they are dealing with to ensure the safety of themselves and others, while also effectively controlling and extinguishing the fire.

Classes B, C, and D refer to different types of combustible materials and require distinct approaches for extinguishing, highlighting the need for situational awareness and knowledge in firefighting operations.
