Safety First
Airman 1st Class Peyton Oesterreich, 49th Aerospace Medicine Squadron bioenvironmental engineer apprentice, opens his hach kit at the Domenici Fitness and Sports Center pool at Holloman Air Force Base, N.M., June 27. The hach kit is used to test water quality and give a proper water analysis to ensure the base pools have safe hydrogen and chlorine levels. In addition to performing water analysis, bioenvironmental engineers also ensure safety of the base and respond to crashes and flight emergencies.
