A33 -- Industrial Local Exhaust Systems (SI)

Industrial exhaust ventilation systems contain, collect, and remove airborne contaminants consisting of particulate matter (dusts, fumes, smokes, fibers), vapors, and gases that can create a hazardous, unhealthy, or undesirable atmosphere. Exhaust systems can also salvage usable material, improve plant housekeeping, and capture and remove excessive heat or moisture. Industrial exhaust systems must comply with ASHRAE Standard 62.1 and other standards as required (e.g., National Fire Protection Agency [NFPA] standards).
