U.S. Air Force Col. Tad Clark, 52nd Fighter Wing vice commander, signs the Fire Prevention Week proclamation letter at Spangdahlem Air Base, Germany, Oct. 4, 2018. Every acting U.S. president has signed a fire prevention proclamation letter since 1925, and Clark continued the tradition as a commemoration. The theme of this year's event is, "Look, listen, learn. Be aware, fire can happen anywhere." (U.S. Air Force photo by Airman 1st Class Valerie Seelye)
