Can you get poisoned from welding galvanized steel?
But there is a risk when it comes to welding galvanized steel. It is called galvanize poisoning. Galvanize poisoning is caused when a person is overexposed to the zinc oxide which is formed when the galvanized coating on steel evaporates at a very high temperature such as the temperatures needed for welding.
How long does it take to get galvanized poisoning?

Is it OK to weld galvanized steel?
Galvanized steel is just normal steel coated with a thick layer of zinc. As for the welding method, once the zinc coating is removed and you’re using the proper safety techniques, you can weld galvanized steel just as you would normal steel.
Why is it bad to weld galvanized steel?

What are the symptoms of metal fume fever?
Clinical presentation: Metal fume fever typically presents with generally non-specific complaints including influenza-like symptoms, fever, shaking chills, arthalgias, myalgias, headache, and malaise. Onset of symptoms typically occurs 4-10 h following the exposure to metal-containing fumes.
How to know if you have galvanize poisoning?
