U.S. Army Garrison Alaska has a new trick up its sleeve in protecting public safety, health and the environment: a specialized foam-free test trailer.

The trailer is designed to eliminate the discharge of chemical fire retardant containing per- and polyfluoroalkyl substances, or PFASs, during testing and training exercises at Fort Wainwright. Currently, several fire trucks and pumpers on the garrison use aqueous, film-forming foam as a fire retardant because it is effective for putting out fuel and aviation fires. Doing so saves lives and protects mission-critical assets.
