Relating to the discharge or use of certain firefighting foams for testing or training.

SB 1898 prohibits the use of firefighting foams containing perfluoroalkyl and polyfluoroalkyl chemicals (PFAS) during firefighter training or equipment testing, except under specific conditions. It requires fire departments to use non-fluorinated foam or alternatives for all training activities and mandates collection of used training foam. Exceptions are allowed only if the foam discharge is legally required or necessary to meet fire safety standards, and if the facility has proper environmental containment measures. The bill directly affects fire departments, training facilities, and firefighting equipment calibration processes across Texas. It does not ban the sale or manufacture of PFAS-containing foams.
