Which type of fire can be extinguished using water?

Water is effective for extinguishing classified fires that involve ordinary combustible materials such as wood, paper, or textiles. The correct answer indicates that wood fires, which typically involve burning materials that are not flammable liquids, gases, or electrical components, can indeed be extinguished using water.

When water is applied to a wood fire, it cools the burning materials below their ignition temperature and also helps to smother the flames by cutting off the oxygen supply to the fire.

In contrast, electrical fires, gasoline fires, and tire fires involve materials that can react dangerously with water. Electrical fires can pose a serious risk of shock when water is used, gasoline fires can spread quickly when water is applied, and tire fires produce highly toxic smoke that can be exacerbated by water due to the burning rubber and other chemicals involved. Therefore, understanding the nature of the fire is crucial for effective and safe extinguishing methods.
