What types of fires can Portable AFFF be used for?

Portable AFFF (Aqueous Film-Forming Foam) is designed specifically for combating flammable liquid fires, which fall under Class B fires. These include fires involving substances like gasoline, oil, and other hydrocarbons. AFFF works by forming a film over the burning liquid, effectively cutting off the oxygen supply and suppressing the flames.

In addition to its primary use for Class B fires, AFFF can also be effective for small fuel fires, making it versatile in certain scenarios. This ability to tackle small fuel fires, along with its performance against Class B fire types, supports the choice that focuses specifically on its functional application in these situations.

While AFFF is highly effective for Class B fires, its application to other classes—such as Class A (ordinary combustibles) or Class C (electrical fires)—is limited or not recommended. This specificity is crucial for selecting the right type of extinguishing agent, ensuring safety and effectiveness in fire suppression efforts.
