Scottie Stevens, an aerospace outside machinist, uses hand signals to direct a crane operator to lower a basket with an item to be cleaned, June 29, 2022, in the chemical cleaning yard at Arnold Air Force Base, Tennessee. The vat contains one of two newly-acquired citrus-based cleaners purchased to replace hydrofluoric acid, a more dangerous chemical. Workers are able to wear less personal protective equipment with the new cleaner. Stevens is wearing a Tyvek suit, but had he been wearing long sleeves, he could have worn an apron instead, in addition to the gloves and face shield. (U.S. Air Force photo by Jill Pickett)
