On October 27, 2017, an Industrial Hygienist with the Consultation Education and Training (CET) Division of the Michigan Occupational Safety and Health Administration (MIOSHA) conducted air monitoring at our facility in response to our request for assistance with evaluating employee exposures to silica while using BW Manufacturing’s grinders and vacuum. 

The air monitoring included breathing zone samples on an employee using the DG-71-ME Hand Grinder connected to an A-101 Pulse Vac and a DG-16-2 Diamond Grinder/Polisher connected to an A-101 Pulse Vac.  These were screening samples that were run long enough to ensure that the sample result’s limit of detection was below the established action level limit of 0.025 mg/m³.

Air Monitoring

The air sampling that was performed at our facility was only considered to be screening samples and do not represent a full shift monitoring period.  If these operations were consistently performed for the full shift, then the Sample Results, found on the enclosed Air Contaminant Data Sheets, would be a relatively accurate employee exposure representation for a full shift.

The test results revealed that the operator using both the DG-71-ME Hand Grinder and the DG-16-2 Diamond Grinder/Polisher was not exposed to concentrations of respirable quartz (silica), respirable cristobalite and respirable nuisance dust in excess of the established limits (i.e., PEL).  The results indicated that silica was not detected on the filters.

These air sample results can be passed on as objective data to employers to utilize when developing their safety and health programs and determining employee exposure levels.  Contractors must be reminded that the working conditions must be similar to the test conditions if this is going to be used as objective data.  The testing was performed outdoors on concrete that contained 50% silica as determined through a bulk sample submitted to the lab.  This objective data would not be applicable to work conditions that contain more than 50% silica or is performed indoors.  Further testing (air monitoring) for indoor environments would be required for use as objective data indoors.
