Staff Sgt. Eric Dasher uses a specialized ultraviolet lamp to test for hydrocarbons on an oxygen gauge at the 379th Expeditionary Maintenance Squadron Precision Measurement Equipment Laboratory, Al Udeid Air Base, Qatar, Feb. 25, 2014. Oxygen gauges are certified hydrocarbon free and oxygen safe so they can be used with liquid oxygen. Dasher is a 379th EMXS PMEL technician deployed from Joint Base Lewis-McChord, Wash., and a Riverton, Ill., native. (U.S. Air Force photo by Master Sgt. David Miller)
