Final answer:
Workers must be protected from hazardous chromium and nickel fumes when welding stainless steel, requiring adequate ventilation and proper PPE.
Step-by-step explanation:
When welding is being done on stainless steel, workers shall be protected from high concentrations of chromium and nickel fumes, which can be hazardous to their health. Welding generates fumes that contain various metals, and certain welding processes involving stainless steel can release significant amounts of chromium and nickel, which, when inhaled, can lead to serious health problems, including respiratory issues and increased risk of lung cancer.
Adequate ventilation, the use of proper personal protective equipment (PPE) like respirators, and adherence to safety protocols are crucial in protecting workers from these harmful substances.
When welding is being done on stainless steel, workers shall be protected from high concentrations of electromagnetic radiation and thermal energy. The electric arc generated during welding can emit high-energy electromagnetic radiation that can burn the retina of an unprotected eye. Additionally, the thermal energy produced during welding can be felt on exposed skin and can cause burns if workers are not adequately protected.
