For several years now, that specific case (Jim Wilson killed by zinc fume fever) is brought out to demonstrate the deadliness of welding galvanized metal. Digging a little deeper, it becomes less clear that it's as dangerous to the average person. It might be more accurate to say "if you're a heavy smoker with COPD, heart disease, diabetes, and high blood pressure, welding galvanized metal might be hazardous to your health." If it's so dangerous, why is the proof of it always that same story where it killed a man who was already very sick? But hey, maybe it's incredibly dangerous. Several years ago, my 60 year old wife wasn't allowed to board a plane until she had transferred the contents of a bottle of shampoo into two small plastic bags. If that's dangerous then I would have to agree that everything is.
