Metal Fume Fever
Metal fume fever is a flu-like poisoning from inhaling zinc oxide fumes when welding galvanized parts. It occurs hours after work and subsides after one to two days.
Physicochemical mechanism of action
During welding of galvanized steel, zinc evaporates and oxidizes in air to form fine zinc oxide particles. These penetrate deep into the lungs and trigger an acute inflammatory response.
Metallurgical relevance & risks during welding
The symptoms – chills, fever, cough, nausea, aching limbs – often appear only hours after work and subside after one to two days. Repeated exposure can permanently irritate the airways. Zinc fever is usually not permanently dangerous, but it is very unpleasant acutely.
Workshop practice & instructions
When welding galvanized parts, remove the zinc coating, use extraction, and ventilate the room. If symptoms occur, get fresh air immediately and seek medical advice.
