• Description:
  Background: Workplace exposure to respirable crystalline silica can cause silicosis, a progressive lung disease marked by scarring and thickening of the lung tissue. Several construction materials, such as brick, block, mortar and concrete contain crystalline silica. Construction tasks that cut, break, grind, abrade, or drill those materials have been associated with overexposure to dust containing respirable crystalline silica. Assessment: NIOSH staff visited the Bricklayers and Allied Craftworkers' Southern Ohio-Kentucky Regional Training Center, Batavia, Ohio on December 19, 2017 and performed industrial hygiene sampling, which measured exposures to respirable dust and respirable crystalline silica while an experienced bricklayer used a handheld electric mixer to mix thinset mortar and water in a 5 gallon plastic bucket with and without a dust control attached to the rim of the bucket. Results: Personal breathing zone respirable dust measurements showed that the dust control reduced exposure by 84%. Unfortunately, the sampling periods were too short to measure the reduction in quartz exposures. Conclusions and Recommendations: Full-shift sampling should be conducted during a tile setting job to determine how well this control works under actual working conditions.
