Metal fume fever - Wikipedia
Metal fume fever, also known as brass founders' ague, brass shakes, zinc shakes, galvie flu, metal dust fever, welding shivers, or Monday morning fever, is an illness primarily caused by exposure to chemicals such as zinc oxide (ZnO), aluminium oxide (Al 2 O 3), or magnesium oxide (MgO) which are produced as byproducts in the fumes that result when certain metals are heated.

Galvanized Sheet Metal: Must-Known Facts and Best Practices
Galvanization is a manufacturing process involving the application of zinc coating to steel to prevent it from rusting. The zinc coating works to protect the base metal. It does this by acting as a barrier to the various corrosive elements. Therefore, it offers a sacial nature that gives a high-quality and long-lasting steel product.

Dangers of heating zinc for science project
Zinc is not a 'toxic gas'; it is an essential micronutrient. The problem is that welders heat a lot of zinc to the vaporization point, creating a cloud of zinc oxide, and then inhale it into their lungs, getting a gross overdose. By way of parallel, instead of taking one …

Is a galvanized fire ring safe? - AskingLot
In a nutshell, burning wood in a galvanized ring should not present a major problem outdoors due to the open ventilation and the rapid mixture of the zinc oxide with the air. The fire can get hot enough to melt the zinc coating, but soon after the zinc is melted away, the ring will begin to rust as you will observe.

Rust On Stainless Steel - Sperko Engineering
Corrosion of "free iron" on stainless steel is always faster than corrosion of the unal-loyed steel itself because the free iron "contamination" is anodic to the stainless steel, so it corrodes to protect the stainless steel, just like zinc corrodes to protect carbon steel when zinc is used as galvanizing.
