Abstract
A study was made to document and evaluate effective techniques for the control of potential health hazards at the Unimin Dividing-Creek Sand Facility (SIC-1446), Millville, New Jersey. This facility supplied washed sand to the glass industry. Two dredges were used to mine sand from flooded areas, following removal of trees and topsoil. A sand/water slurry was pumped to a scalper to remove rocks and slime. Personal exposures to respirable quartz (14808607) dust were shown to range between less than 0.02 to 0.05mg/m3 for nine collected samples, none of which exceeded allowable limits. Area air samples taken near the railroad car filling operation and the sand screening area showed that there was a potential for exposures to elevated levels in these areas. Deficiencies were identified in the design and maintenance of equipment, in work practices, and in ventilation control systems which were identified for modification. Control methods in place at the operation included environmental monitoring programs, a respiratory protection program, good housekeeping practices, and equipment maintenance.
