What are the types of contaminants can result from welding cleaning or painting?

Welding, cleaning, and painting can generate various contaminants, including particulate matter such as metal fumes and dust, which can arise from welding processes. Solvents and volatile organic compounds (VOCs) may be released during cleaning and painting activities. Additionally, hazardous materials like heavy metals (e.g., lead, chromium) can be present in coatings or welding rods. Proper ventilation and safety measures are essential to minimize exposure to these contaminants.
