On Friday December 22, 2017, the U.S. Court of Appeals for the District of Columbia Circuit rejected all of American industry’s many challenges to the Occupational Safety and Health Administration’s (OSHA) new silica dust standard, 29 C.F.R. §§ 1910.1053 and 1926.1153, which went into effect last September. The court emphasized OSHA's decision was reasonable in its standard.
However, the North America’s Building Trades Unions was able to convince the court that OSHA's explanation for not requiring medical removal protection failed to pass muster. The court has remanded that issue for reconsideration or further explanation.
