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.
