Why there is no straightforward replacement in most cases:
Physics:
PFAS-free foam extinguishing agents are more viscous than conventional PFAS-containing foam extinguishing agents. Proportioning systems, sprinklers/nozzles, or pipes may need to be adapted to ensure reliable operation.
Extinguishing effect:
PFAS-free foam extinguishing agents do not form a water film. Firefighting is mainly achieved through higher foam stability, foaming, and foam blanket. It is therefore necessary to adapt the existing extinguishing system to the foam extinguishing agent.
