Toxic substances in aqueous film forming foam (AFFF) may cause cancer in the firefighters who use it. Firefighting foams have contained perfluoroalkyl and polyfluoroalkyl substances (PFAS) since the 1960s, and public concern about the man-made chemicals is growing.
How Are People Exposed to PFAS?
People get exposed to PFAS by consuming contaminated water and food, using products made with PFAS, or breathing PFAS in the air. Avoiding PFAS is nearly impossible, as these “forever chemicals” exist in our air, water, and soil and have no known “half-life,” or period of decay.
Exposure to PFAS will not cause immediate harm, but the chemicals build up in your body in a process known as bioaccumulation. The more PFAS you are exposed to, the higher your likelihood of adverse health effects.
Unfortunately, firefighting foams used by both civilian and military firefighters contain PFAS and increase PFAS exposure to dangerous levels. These chemicals also contaminate the ground water and environment surrounding military bases where AFFF is used. Serving in the military or working as a firefighter can expose you to too many PFAS and cause health problems.
