OSHA's silica rule confuses and concerns construction contractors
Silicosis is a lung disease common among construction workers, including lifelong bricklayers. The disease is caused by inhaling crystalline silica dust, created when drills and saws buzz into bricks, concrete, and mortar.
New OSHA rules lowering exposure levels to respirable silica dust in general industry and construction were passed in 2016, but federal enforcement has been delayed until September.
