The Mine Safety and Health Administration (MSHA) rule will reduce coal-dust exposure limits by a quarter for underground mines and improve requirements for air sampling and monitoring in an attempt to reduce respiratory disease. It will take advantage of new technology to provide real-time monitoring of dust levels, which would allow miners and supervisors to avoid periods of high coal dust.

“Today we advance a very basic principle: you shouldn’t have to sacrifice your life for your livelihood,” Labor Secretary Thomas Perez said in a statement. “But that’s been the fate of more than 76,000 miners who have died at least in part because of black lung since 1968.”
