  1. Purpose. This CertAlert provides information and guidance to airport operators regarding

optional equipment for use in testing Aqueous Film Forming Foam (AFFF) systems on their

Aircraft Rescue and Firefighting vehicles. It also provides information on current research into

fluorine-free firefighting foams, due to recent concerns over the use and discharge of AFFF at

airports. This guidance has been prepared in response to a directive in the FAA Reauthorization

Act of 2018, described in further detail below, and it does not revise or replace any previously

issued guidance.
