Which types of fires can clean agent extinguishers effectively combat?

Clean agent extinguishers are specifically designed to combat fires that involve flammable liquids and gases (Class B) as well as fires that involve electrical equipment (Class C). The effectiveness of clean agents comes from their ability to interrupt the combustion process without leaving residue that could damage sensitive equipment, making them ideal for situations where minimizing collateral damage is essential.

Class A fires, which involve ordinary combustibles like wood, paper, and textiles, can also be extinguished by clean agents, although they are typically more effective with Class B and C fires. This versatility allows clean agents to be used in various environments, including data centers, laboratories, and other areas where both electrical devices and flammable liquids may be present, justifying the inclusion of Class A fires as well.

The other options focus on limited classifications of fires, which restrict the utility of clean agent extinguishers. Understanding the application of clean agents and their capabilities is crucial for effective fire response and safety measures in environments susceptible to multiple types of fires.
