Which type of fire involves combustible materials such as wood and paper?

A Class A fire specifically involves ordinary combustible materials, which include substances like wood, paper, cloth, and some plastics. These materials tend to ignite easily and can produce a significant amount of ash when burned. This classification is crucial for selecting the appropriate fire extinguisher, as Class A fires require different extinguishing agents than other classes of fires.

In contrast, Class B fires are associated with flammable liquids and gases, Class C fires involve electrical equipment, and Class D fires deal with combustible metals. Understanding these classifications helps ensure the correct type of fire extinguisher is used in emergency situations to effectively and safely extinguish the fire.
