A Class "A" fire typically involves which of the following materials?

A Class "A" fire is characterized by the involvement of ordinary combustible materials, primarily those that produce ash when burned. Wood, coal, paper, and similar substances fall under this category. This type of fire is common and can typically be extinguished with water or fire extinguishers designed for Class "A" fires.

In contrast, the other options pertain to different classes of fire. Gasoline or oil would fall under Class "B" fires, which involve flammable liquids and gases. Paint or grease may also be classified as Class "B," depending on their composition. Electrical equipment is associated with Class "C" fires, which involve live electrical components. Understanding these distinctions is crucial for effective fire safety practices, as each type of fire requires specific extinguishing methods. Thus, the correct identification of a Class "A" fire’s materials is important for both safety and prevention.
