Which class of fire extinguishers should be used for building protection?

The most appropriate response indicates that all classes of fire extinguishers can be utilized for building protection, as each class addresses different types of fire hazards that may occur within a building.

Class A extinguishers are designed to fight fires involving ordinary combustibles such as wood, paper, and cloth, which are frequently found in buildings. This makes them essential for protecting against common fire risks in any structure.

Class B extinguishers are effective against flammable liquids and gases, including fire hazards associated with paints, solvents, and fuels. In commercial or industrial buildings, the presence of these materials makes Class B extinguishers crucial for comprehensive fire protection.

Class C extinguishers are specialized for electrical fires, which can occur due to faulty wiring or electrical equipment present within a building. The ability to safely extinguish these fires is vital to protect both the structure and its inhabitants without risking injury from electrical discharge.

By incorporating all classes of fire extinguishers, building protection strategies can effectively address a broad spectrum of potential fire risks, ensuring a safer environment.
