Checking SCBA
U.S. Air Force Staff Sgt. Russell Woolstenhulme, 380th Expeditionary Civil Engineer Squadron emergency management craftsman, prepares his self-contained breathing apparatus on the scene of an exercise chemical threat area at an undisclosed location in Southwest Asia Sept. 20, 2013. When a chemical threat is suspected, emergency management personnel will wear the SCBA for safety. Woolstenhulme calls Price, Utah, home and is deployed from Hurlburt Field, Fla.
