What types of contaminants can result from welding cleaning and painting?

Welding, cleaning, and painting processes can result in various contaminants, including metal fumes, volatile organic compounds (VOCs), and particulate matter. During welding, harmful metals like lead, cadmium, and nickel can be released into the air. Cleaning agents may introduce solvents and chemicals that can emit VOCs, while painting can produce aerosols and paint overspray. Proper ventilation and protective measures are essential to minimize exposure to these hazardous substances.
