Perfluoroalkyl and polyfluoroalkyl substances (PFAS) are a group of man-made chemicals that have been used in a variety of industrial and consumer products. They are resistant to heat, water, and oil, which makes them useful in a range of applications, including fire resistant (FR) clothing.
PFAS are of concern because they are persistent in the environment and can accumulate in the human body over time. Some studies have suggested that exposure to PFAS may be linked to a variety of health problems, including cancer, liver damage, immune system problems, and endocrine disruption.
FR clothing manufacturers are aware of the potential health risks associated with PFAS and are working to reduce or eliminate the use of these chemicals in their products. Many companies have developed alternatives to PFAS that provide similar performance benefits without the potential health risks. If you are concerned about exposure to PFAS in your FR clothing, you should look for clothing that is made with alternative materials or that is PFAS-free.
