Which of the following is not a recommended protective step when welding galvanized steel?

• A. Use local exhaust ventilation
• B. Remove galvanised coatings when possible
• C. Inhale fumes to acclimate
• D. Use respirator if needed

Answer: (C)

When welding galvanized steel, the main concern is inhaling zinc oxide fumes, which can irritate the respiratory system and cause metal fume fever. The protective steps that actually help reduce this hazard include using local exhaust ventilation to capture fumes at the source, removing the galvanized coating when possible to lower zinc exposure, and wearing a suitable respirator if ventilation can’t fully control the fumes. Deliberately inhaling fumes to acclimate is not a safe or protective practice—there’s no benefit to “getting used to” the fumes, and exposure can lead to illness. The safer approach is to minimize exposure through effective ventilation, coating removal when feasible, and appropriate respiratory protection.
