Billy Clemons, 17th Civil Engineer Squadron assistant chief of prevention, guides Cristian Quintanilla, junior firefighter camp student, to extinguish a controlled class-B fire, at Goodfellow Air Force Base, Texas, July 13, 2022. Class B fire extinguishers contain carbon dioxide, which removes oxygen from the fire and suffocates the flames. (U.S. Air Force photo by Airman 1st Class Zachary Heimbuch)
