Abstract |
Worker exposures to dust and free silica were surveyed at Engelhard Minerals and Chemicals Corporation in Attapulgus, Georgia, March 22-26, 1976. The company employed about 395 workers and provided medical and industrial hygiene services through local consultants. Dust concentrations sometimes exceeded OSHA standards of 5 and 15 milligrams per cubic meter for respirable and total dust, respectively. Free silica concentrations were within acceptable limits; the OSHA standard was not provided. Various amounts of attapulgite clay were found in the dust samples. Noise levels ranged from 73 to 105 decibels relative to the A-weighted scale. The author recommends improved ventilation and housekeeping procedures, use of hearing protection devices, and reduction of radiant heat release near the dryers. |
