Which characteristics are associated with Class A fires?

• A. Involve flammable gases
• B. Include electrical equipment
• C. Involve ordinary combustibles like wood, paper, and cloth
• D. Include burning metals

Answer: (C)

Class A fires are specifically characterized by the involvement of ordinary combustibles such as wood, paper, and cloth. These types of materials are common and represent the most frequent type of fire encountered in residential and commercial settings. Class A fires require specific extinguishing agents usually involving water or foam, which can effectively cool and suppress these flames. In contrast, the other options pertain to different classes of fires. For example, flammable gases are associated with Class B fires, while electrical equipment is categorized under Class C fires. Burning metals, such as magnesium and sodium, relate to Class D fires, which require specialized extinguishing methods. Each class of fire has distinct characteristics that dictate the proper fire suppression strategies, making the identification of Class A fires pertinent for effective firefighting.
