What are Class A fires?

Class A fires involve ordinary combustible materials that can leave ash after being burned. This category includes common substances like wood, paper, rubber, and certain types of textiles. When these materials ignite, they typically produce embers and ash as they burn, making them easily identifiable as Class A fires.

Understanding the classification of fires is crucial for firefighters in order to select the appropriate extinguishing agents and methods. For example, water can be effectively used to extinguish Class A fires, as it cools the burning materials and helps to eliminate the fire.

The other categories of fires refer to different materials that do not leave ash or require other methods of suppression. Energized electrical equipment (Class C fires), combustible cooking oils and fats (Class K fires), and flammable liquids and gases (Class B fires) are all distinct classes that necessitate specialized approaches and techniques for safe and effective extinguishment.
