A 54-year-old worker died after he fell into a vat of sulfuric acid at a South Lyon-based steel manufacturing firm (Michigan) in what is being described as a "serious industrial accident." The man was fully submerged in the 10 percent to 12 percent sulfuric acid solution as his Michigan Seamless Tube co-workers worked desperately to pull him from the industrial container, burning themselves from the at least 160-degree chemical solution, Fire Chief Robert Vogel said.

An uncommon source of carbon monoxide poisoning—industrial gas-burning fryers—caused carbon monoxide poisoning among a large group of workers at an industrial kitchen, according to an investigation published in the CDC’s Morbidity and Mortality Weekly Report (MMWR). Carbon monoxide is a colorless, odorless, and potentially deadly gas.
