NIGP 34521 Extraction Equipment For The Removal Of Exhaust Gases And Other Vapors From Buildings (OSHA), an Item code, covers environmental gas extraction and atmospheric monitoring systems that state and local governments procure to capture, remove, and document hazardous gases and vapors from municipal facilities. The work spans EPA-certified refrigerant recovery and destruction, fixed atmospheric monitoring sensors for detection of hydrogen sulfide, methane, chlorine, ammonia, and other hazardous gases, and replacement or installation of exhaust systems in water treatment labs, paint booths, and confined spaces.
