A respirator is a device worn by workers to protect against harmful dust, fumes, vapors or gases. Respirators come in a wide range of types and sizes used by the military, private industry and the public.

Respirators used at Hanford typically fall into two categories: air-purifying respirators (APRs) and air-supplying respirators. APRs use a filter cartridge to clean the air before it enters the respiratory tract. Supplied-air respirators provide clean breathing air from either a hose and air compressor or an air cylinder that the worker wears on their back. The self-contained breathing apparatus (SCBA) is one type of supplied-air respirator worn while working inside Hanford's tank farms.
