Flame retardants have been linked to neurological damage, hormone disruption, and cancer. A significant concern is the bioaccumulation of certain flame retardants in humans, leading to persistent, chronic health issues as levels of these toxic substances increase within the body over time. Firefighters, who experience substantial exposure to flame retardants, are leading the charge to eliminate their use to combat associated health problems. Chemical exposure on duty makes cancer the leading cause of firefighter fatalities.
