What kind of fires is AFFF specifically effective against?

• A. Electrical fires
• B. Ordinary material fires
• C. Flammable liquid fires
• D. Combustible metals fires

Answer: (C)

Aqueous Film-Forming Foam (AFFF) is particularly effective against flammable liquid fires, such as those involving fuels, oils, and other hydrocarbon products. AFFF works by forming a film on the surface of the burning liquid, effectively sealing off the fuel from oxygen and suppressing the flames. This suppression method not only extinguishes the fire but also helps prevent reignition, making AFFF a crucial fire suppression agent in situations where flammable liquids are involved. In contrast, AFFF is not suitable for all types of fires. Electrical fires require agents that do not conduct electricity, while ordinary material fires, such as those involving wood or paper, may not necessitate the specific properties of AFFF. Additionally, combustible metals fires require specialized agents that can handle the unique combustion characteristics of metals, which AFFF cannot effectively address. Thus, the specificity of AFFF's effectiveness is what makes the correct choice focused on flammable liquid fires.
