• Description:
  Respirable dust measurements taken by a GCA respirable dust monitor (SIC-3811) were compared to those taken by a standard mass respirable sampling system (MSA). Air samples were collected at three granite sheds in Barne, Vermont, where finished monuments were produced. MSA pumps were run 7 to 8 hours per day, and GCA readings were taken from 1 to 8 minute sampling periods within 1 to 2 hour intervals. Average respirable dust concentrations measured by MSA in sheds A, B and C were 0.373, 0.374 and 0.536 milligrams per cubic meter (mg/m3), respectively. Corresponding readings taken by the GCA, were 0.619, 0.589 and 0.741mg/m3. The three major problems encountered with the GCA were malfunctioning of the polyester disc advancing mechanism, the start switch and the 10 millimeter nylon cyclone. The authors suggest that the higher GCA readings, compared to MSA measurements, may be related to the cyclone malfunction; the GCA monitor is designed to operate at a flow rate of 2.0 liters per minute, while the cyclone operates at 1.7 liters per minute.
