Air quality management for small and midsized shops

摘要

Welding, plasma cutting, and laser cutting produce fumes, often referred to as smoke, which consist of airborne dust particles made up of tiny pieces of dry solid matter. This dust can reduce air quality, irritate the eyes or skin, damage the lungs, and become a hazard when settling on surfaces. Processing fumes can contain lead oxide, iron oxide, nickel, manganese, copper, chromium, cadmium, and zinc oxide. Some welding processes can also produce toxic gasses like nitrogen dioxide, carbon monoxide, and ozone.
