Which metals or coatings produce toxic fumes when cut?

The correct answer focuses on the specific metals and coatings that are known to release toxic fumes when subjected to cutting processes. Cadmium, mercury, lead, zinc, chromium, and beryllium are particularly hazardous because they can produce harmful vapors and particulates when heated or vaporized during cutting.

Cadmium is a known carcinogen and can cause serious lung and kidney damage when inhaled. Mercury is highly toxic, affecting the nervous system and various organ systems. Lead exposure can result in neurological issues and other serious health problems, particularly in children. Zinc can produce zinc oxide fumes when heated, which may lead to metal fume fever—a flu-like illness. Chromium and beryllium are associated with respiratory ailments and are also classified as carcinogens.

The other options, while they may have their concerns, do not generally produce toxic fumes to the same degree or with the same urgency when cut. Understanding this distinction emphasizes the importance of proper training and safety precautions when working with metals that are known to emit harmful substances, thus ensuring a safer working environment.
