Welding fumes are a complex mixture of airborne particles and gases generated during welding, thermal cutting and related metalworking activities. These fumes may contain a range of hazardous substances, including manganese, chromium, nickel, lead and ultrafine particulates that can be inhaled deeply into the lungs. Exposure to welding fumes can contribute to serious short- and long-term health effects, such as:
International and national health authorities classify welding fumes as carcinogenic, which means no level of exposure is considered completely safe. Effective monitoring and well-designed control measures are essential to helping protect workers in welding-intensive industries.
