CAS: Preventing environmental contamination
Cynthia Miller, Central Accumulation Site environmental technician, individually wraps lithium batteries for disposal on Seymour Johnson Air Force Base, N.C., March 12, 2010. In the past, technicians taped battery terminals so they could not touch and start a fire, now as an added precaution they are also placed in individual plastic bags. Miller hails from Goldsboro, N.C. (U.S. Air Force photo/Senior Airman Rae Perry)
