MSHA or OSHA?

摘要

Intense federal regulation of workplace safety and health began when Congress introduced civil penalties for mines with the Federal Coal Mine Health and Safety Act of 1969, and for other employers with the Occupational Safety and Health Act of 1970. The Coal Act was amended in 1977 to become the Federal Mine Safety and Health Act, with enlarged sanctions. In 2006, the Mine Improvement and Emergency Response Act further raised requirements and sanctions for mines.
