Question: A welder is working on a galvanized steel pipe in a poorly ventilated area, experiencing difficulty breathing and a metallic taste in their mouth. What is the most likely cause of these symptoms?
Answer options:
- Exposure to carbon dioxide (CO2)
- Overexposure to iron oxide fumes ✅ Zinc fume fever
- Nitrogen narcosis from shielding gas
Correct answer: Zinc fume fever
Explanation: Welding on galvanized steel releases zinc fumes. Exposure to high concentrations of these fumes can lead to zinc fume fever, characterized by flu-like symptoms including difficulty breathing and a metallic taste in the mouth. CO2 is generally not a primary concern with these specific symptoms, iron oxide fumes cause different symptoms, and nitrogen narcosis is not relevant to welding fumes.
