How long will one 5-gallon can of AFFF last?

The duration a 5-gallon can of Aqueous Film Forming Foam (AFFF) lasts is typically around 60 seconds when used effectively. This timeframe is critical for firefighting operations because it provides the necessary window to suppress flames, especially in scenarios such as a fire involving flammable liquids. Understanding the duration helps personnel gauge how much foam can be deployed and allows them to plan for refills or supplementary resources if necessary. The specified time reflects typical application scenarios and operational guidelines, ensuring that responders can maximize the effectiveness of the foam in emergency situations while maintaining safety protocols.
