Question: Why is proper ventilation crucial when welding stainless steel?
Answer options: ✅ To remove hazardous chromium and nickel fumes that can cause respiratory issues
- To prevent stainless steel from discolouring due to heat
- To reduce the magnetic properties of the weld
- To ensure a smooth arc characteristic
Correct answer: To remove hazardous chromium and nickel fumes that can cause respiratory issues
Explanation: Welding stainless steel can produce fumes containing hazardous chromium (especially hexavalent chromium) and nickel, which are known respiratory irritants and carcinogens. Adequate ventilation or local exhaust is critical for welder safety.
