Following Snohomish Regional Fire and Rescue’s (SRFR) switch to safer type of foam, fire suppressants used at all central county fire agencies are now free of hazardous “forever” chemicals. SRFR stopped using AFFF (Aqueous Film-Forming Foam) in July 2023 after findings that the suppressant contains high concentrations of PFAs — chemicals that do not break down in either the environment or human body. “By transitioning to Novacool, a fluorine-free foam, we reduced long-term environmental risk while maintaining effective firefighting capability,” said Brett Fetcho, a SRFR deputy chief.
PFAs have been linked to thyroid disease, high cholesterol, birth defects, and several types of cancer. The chemicals migrate through groundwater, build up in the food chain, and are difficult to contain and clean up. The state banned the use of AFFF in 2018 for firefighter training, and the foam is no longer sold in Washington. But fire departments are allowed to use their existing stock. SRFR changed to Novacool in July 2023, removing 510 gallons of AFFF from its inventory.
