How long will an AFFF firefighting extinguisher last under continuous use?

An AFFF (Aqueous Film-Forming Foam) firefighting extinguisher is designed for use in combating flammable liquid fires and operates effectively for a limited duration, which is crucial information for firefighting operations. The typical operation time for an AFFF extinguisher under continuous use is approximately 55 to 65 seconds. This duration allows firefighters to assess the situation, apply the foam to the fire effectively, and ensure safety while managing the fire.

Understanding this time frame helps ensure that firefighters can plan their actions accordingly, regroup if necessary, and maintain a continuous approach to suppressing the fire until additional resources can be deployed if needed. The effectiveness of the foam in providing a blanket over the burning material and suppressing flames also supports this operational window, making it essential knowledge for anyone involved in damage control and firefighting.
