PFAS are also key components in aqueous film-forming foam (AFFF), which is used to fight petroleum-based fires at aviation and manufacturing facilities. For decades, AFFF containing PFAS has been used extensively at airports throughout the world to protect the safety of passengers, crew, and others. The FAA requires that commercial airports train with, calibrate equipment with, and use the best performing AFFF fire suppression systems. AFFF is required to be used at airports and must be certified to meet strict performance specifications, including those mandated by the U.S. Department of Defense Military Specifications.
Lynleigh Love and Chris Crosby of SCS Engineers discuss the risks and issues with PFAS-based firefighting foam used at airports. The authors cover the regulatory climate, contamination investigations, operational and environmental management and litigation, along with alternatives to using traditional AFFF. There are some possible alternatives that can mitigate health risks in your community.
