I confirm about galvanized steel. I used to work in an elevator shop and weld that a lot with no aspiration system and had to quit before 1 year for health purpose order of my doctor, started having symptomes
after few month ,same for the guy who was working with me and the previous welder who worked there for over 6 year died.
Oh my god. This must be a warning sign from the Gods. I was littlerally about to go pick up some break cleaner to clean off the oil on some tube I was welding on for my job. Thanks for posting this, it may have saved my life!
"In the U.S., the Occupational Safety and Health Administration requires that MSDS be available to employees for potentially harmful substances handled in the workplace under the Hazard Communication regulation. The MSDS is also required to be made available to local fire departments and local and state emergency planning officials under Section 311 of the Emergency Planning and Community Right-to-Know Act. The American Chemical Society defines Chemical Abstracts Service Registry Numbers (CAS numbers) which provide a unique number for each chemical and are also used internationally in MSDSs."

I use to work in a plant for 3 years that made phosgene gas, I was caught up a leak and inhaled a lot of gas. I spent the next 14 hours in medical under oxygen. I ended up with a sever case of chemical pneumonia it took me about 6 months to fully recover. Phosgene is an acid gas and when mixed with the fluid in your lungs becomes very corrosive. If anyone is unfortunate and inhales phosgene please go to the hospital they can put you on a breathing machine while your lungs heal. One breath will do a lot of damage as did to the guy in the article. If he would have taken a second breath he may not be alive. As a welder for the past 24 years my advice to everyone is to use a torch or buffer to remove any oil, don't use any type of degreaser.
