What type of fire occurs when ordinary combustibles, such as paper or wood, catch fire?

The type of fire that occurs when ordinary combustibles, such as paper or wood, catch fire is classified as a Class A fire. This classification is designated for fires that involve solid materials that are typically organic in nature, and they are the most common type of fire encountered.

Class A fires are characterized by the burning of common flammable materials like wood, paper, cloth, and certain types of plastics. When such materials ignite, they can produce embers and ash, requiring specific firefighting techniques such as the use of water or certain foam agents designed to extinguish these types of fires effectively.

Understanding this classification is crucial for both fire safety and response, as it dictates the appropriate fire extinguishing agents and methods to be used in the event of a fire involving these materials. This contrasts with other fire classes, which involve different materials and fire extinguishing methods. For example, Class B fires involve flammable liquids and gases, while Class C fires include electrical equipment, necessitating appropriate measures to avoid further hazards.
