Fumes from which metal are commonly associated with fume fever when welding?

• A. Stainless steel
• B. Zinc / Galvanized
• C. Hot rolled steel
• D. Cold rolled steel

Answer: (B)

Metal fume fever happens when metal oxide fumes are inhaled during welding. The most common source is zinc from galvanized steel. Welding galvanized steel releases zinc oxide fumes, which can trigger flu-like symptoms—feverish feeling, chills, sweating, headache, nausea, and fatigue—often a few hours after exposure and usually resolving in 24 to 48 hours. Other metals welded in steel (like the iron in hot or cold rolled steel or the chromium/nickel in stainless) can produce fumes, but the classic fume fever is most closely linked to zinc from galvanized coatings. To reduce risk, use proper ventilation, respirators, and consider removing or limiting the zinc coating when possible.
