Abstract
Exposure to talc (14807966) was evaluated at the Plymouth Rubber Company (SIC-3069) in Canton, Massachusetts, on January 23, 1973. Four personal air samples were collected from the rubber band manufacturing area for comparison with samples collected in a former survey. Concentrations were 1.9, 2.2, 3.0, and 4.2 milligrams per cubic meter (mg/CuM) for the packer, improved extruder unit, old extruder unit, and vacuumer, respectively. Exposure was reduced to half of the earlier measurements at the improved extruder unit. By estimation, total dust concentration decreased from previous values by a factor of 2. The present OSHA standards for nonfibrous talc is 20 million particles per cubic foot. Silica was reduced from 3 to 2.5mg/CuM was exceeded in two samples. The authors conclude that many of the ventilation and housekeeping improvements since the initial survey have produced successful results, however, additional improvements were recommended in the rod stripping and old extruding unit areas.
