VIDEO: San Francisco is poised to become the first city in the country to issue a ban on firefighter clothing manufactured with so-called forever chemicals.
Local lawmakers are expected to pass an ordinance on Tuesday prohibiting the use of protective equipment made with per- and polyfluoroalkyl substances, or PFAS. The long-lasting compounds do not break down, allowing them to linger almost permanently in the environment.
PFAS can be ingested or absorbed into the skin and have been linked to harmful health effects, including decreased fertility, low-birth weight and developmental delays in children, a higher risk of certain cancers and increased cholesterol levels, according to the Environmental Protection Agency.
