Which of the following is NOT a classification for extinguishing agents mentioned?

The classification for extinguishing agents typically includes various materials that can either fuel a fire or be used to put it out. Non-combustible solids refer to materials that do not ignite or burn, which is why they do not fit the category of extinguishing agents. Instead, they are often part of the building structure or safety equipment that aids in fire containment and prevention.

On the other hand, combustible gases, flammable liquids, and electrical hazards are all materials that can contribute to fire and need specific extinguishing methods tailored to their properties. Understanding these classifications is essential for effective fire safety training and emergency response in correctional facilities. Non-combustible solids play a role in fire safety, but they are not considered extinguishing agents.
