Metal fume fever or zinc chills are most commonly caused from welding on which of the following?

Metal fume fever, often referred to as zinc chills, occurs as a result of inhaling zinc oxide fumes which can be released when welding galvanized steel. Galvanized steel is coated with a layer of zinc to prevent corrosion, and during welding, the heat can vaporize the zinc, creating fumes that, when inhaled, can lead to flu-like symptoms.

This condition is particularly associated with welding on galvanized steel because the zinc content is significant and the quantities of fumes released can be substantial. The symptoms typically include fever, chills, and metallic taste in the mouth due to the body’s reaction to the inhaled zinc oxide particles.

In contrast, welding on stainless steel, aluminum, or copper results in different fume exposures and does not commonly produce metal fume fever like galvanized steel does, as they do not emit zinc fumes when processed. Understanding the specific materials and their properties is crucial for anyone working in welding or metal fabrication to prevent health-related issues.
