Fires that result from ordinary combustibles, such as wood and paper, are classified as Class _____.

Fires that arise from ordinary combustibles like wood and paper are classified as Class A fires. This classification is crucial because Class A fires generally involve solid materials that combust, and they require specific methods for extinguishment. Typically, water or foam is effective in putting out Class A fires because these materials cool the burning substances and remove heat, which is one of the key elements in the fire triangle (oxygen, heat, and fuel).

Understanding the different classes of fires is essential for safety and effective firefighting. Other fire classes are associated with various types of combustible materials. For example, Class B fires involve flammable liquids and gases, while Class C fires pertain to energized electrical equipment. Each class has recommended extinguishing methods tailored to the materials involved, highlighting the importance of the correct classification in emergency response situations.
