Understanding the Shift from AFFF to SFFF: Enhancing Firefighter Safety and Performance In this article we are going to examine: Why AFFF foam has become popular for firefighting applications Why AFFF is being phased out of firefighting What you should expect from the new SFFF foam agents that are replacing AFFF agents As the fire service […]
As you switch over to SFFF formulations, you face a few different challenges. Have you explored them? One of the first major challenges you face is that SFFF chemical formulations can vary widely by manufacturer. Each manufacturer’s SFFF agent formulation may be significantly different from other producers, even proprietary. Think about that for a minute […]
Finished-foam quality — a measure of durability or usefulness of a foam blanket — is measured two ways; expansion ratio and 25% drain time. Finished-foam quality is a function of the volume of air drawn into the nozzle and the amount of mechanical agitation that occurs in the nozzle or nozzle-foam tube. Expansion ratio is […]
