• Description:
  Diesel exhaust is considered a carcinogen to humans by the International Agency for Research on Cancer (IARC). Miners are one of the highest exposed occupations, and those who work outside of cabs, such as blasters, surveyors, and roof bolters, can be the highest exposed working groups. One potential control technology to help reduce these exposures is to use a canopy air curtain (CAC). The CAC delivers clean filtered air over the operator's breathing zone. It has been designed for reducing exposures to respirable dust for roof bolters and shuttle car operators. This study, conducted by researchers from the National Institute for Occupational Safety and Health (NIOSH), modified the CAC design to enable the technology to capture diesel particulate matter (DPM) instead of dust and tested the efficiency of the CAC to reduce DPM concentrations underneath the CAC. With a 3-inch lip, the CAC reduced DPM exposures by over 90% at its center and about 80% in the left and right front of the canopy, demonstrating the effectiveness of the redesigned CAC. Therefore, the CAC may provide protection to blasters and other types of mine workers working under a canopy. [Description provided by NIOSH]
