Airmen assigned to the 380th Expeditionary Civil Engineer Squadron Emergency Management flight cap a leaking gate valve of a simulated pressurized chlorine cylinder during a hazardous materials exercise at Al Dhafra Air Base, United Arab Emirates, Jan. 4, 2019. The exercise was designed to be a Department of Defense certification for three Airmen in the fire department and an annual refresher training for the EM flight. The Airmen were instructed to contain leaks on a pressurized chlorine cylinder, a one-ton cryo-tank, and a rail car, all after donning a Level-A suit. (U.S. Air Force photo by Senior Airman Mya M.
