Texas Fire Extinguisher Practice Exam

A wood fire falls under Class A fires because this classification is designated for ordinary combustible materials. Class A fires typically involve solid materials such as wood, paper, cloth, rubber, and some plastics. When these materials ignite, they burn with a visible flame and produce ash upon burning, which is characteristic of Class A fires.

Class A extinguishers are suitable for such fires, as they are designed to cool the burning material and prevent re-ignition. This classification is essential for understanding fire safety and selecting the appropriate fire extinguisher for effective fire suppression in situations involving common combustibles like wood.

In contrast, the other classes pertain to different types of materials: Class B includes flammable liquids and gases, Class C pertains to electrical fires, and Class D is for combustible metals. Each of these classes requires specific methods and materials for effective extinguishment, making the understanding of Class A fires critical for safety in environments where wood and similar materials are present.
