Worker exposures to dust and free silica (7631869) were surveyed at Engelhard Minerals and Chemicals Corporation in Attapulgus, Georgia, from March 22 to 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.
