MSHA: Coal dust samples show mines are complying with rule

摘要

Arlington, VA - Recent results of coal dust samples indicate that mines are complying with a final rule intended to decrease miner exposure to harmful coal dust, according to the Mine Safety and Health Administration. Nearly 7,500 samples of respirable dust were tested during the two months following the rule's Aug. 1 effective date. Of those, about 99 percent were compliant, the agency announced on Oct. 20. Nearly 0.5 percent of the 4,255 samples collected by MSHA exceeded compliance levels, and 1.3 percent of the 3,201 samples submitted by mine operators exceeded compliance levels.
