Critical national defense mission keeps AEDC open amid pandemic
Chris Easterly, an ironworker, welds a joint on a C-1 pipe support stand April 1 in the Model and Machine Shop at Arnold Air Force Base, Tenn. Easterly is wearing a welding helmet with a powered air purifying respirator (PAPR) and a hood, which provides protection from smoke and fumes. The PAPR is not required for welding non-stainless steel, but is being explored as a risk mitigation option for when craftsworkers need to be closer than six feet apart to complete the task.
