The U.S. Mine Safety and Health Administration, or MSHA, announced it is implementing a medical action plan, after a review of examination results showed roughly 15% to 20% of its inspectors and technical personnel do not meet the agency's medical standards.

"In response, MSHA will implement an individualized assessment process for employees who do not meet medical standards," the agency noted in an Aug. 9 release, adding that the problem has been growing for several years.

"The process will incorporate requirements for reasonable accommodation, resolve issues efficiently and effectively, and be conducted in a consistent and fair manner," it added.
