Aqueous Film-Forming Foam (AFFF) has been a vital tool in firefighting for decades, particularly effective in extinguishing petroleum-based fires. However, recent studies have revealed that AFFF contains harmful chemicals known as PFAS (per- and polyfluoroalkyl substances), which have been linked to severe health issues, including cancer, liver damage, and immune system dysfunction. These toxic chemicals can persist in the environment and the human body for years, posing long-term health risks.
