Trump administration is OK with more toxic dust

The Trump administration is reconsidering an Obama-era rule that protects people from exposure to a substance linked to deadly lung conditions, including cancer and beryllium lung disease. Beryllium is a lightweight metal that makes steel stronger, but when it’s crushed into dust, workers in shipyards and other construction sites breathe it in. The rule set lower limits on exposure to the toxin, but now the U.S. Labor Department’s Occupational Safety and Health Administration says it won’t enforce the more protective standard and is instead considering weakening it. The Trump administration offered no rationale for walking back worker protections.
