What class of fire corresponds to ordinary combustibles?

Green Triangle (A)
Red Square (B)
Blue Circle (C)
Yellow Star (D)

The correct answer is: Green Triangle (A)

The class of fire that corresponds to ordinary combustibles, such as wood, paper, cloth, and some plastics, is represented by the Green Triangle symbol, which denotes Class A fires. Class A fires are characterized by their fuel source, which involves common combustible materials that can ignite and burn in the presence of heat. This classification system is widely recognized and is important for effective fire safety and response; using the appropriate fire extinguisher for Class A fires is crucial for safety and effective fire suppression. In contrast, the other options represent different classes of fires: Class B typically relates to flammable liquids and gases, Class C pertains to electrical fires, and Class D is focused on combustible metals. Understanding these classifications helps in choosing the right extinguishing agent and method to deal with a fire appropriately, ensuring a higher chance of successful containment and minimizing danger to individuals and property.
