Abstract
Silica (7631869) exposure and silicosis among workers at a silica production facility (SIC-2819) were investigated by NIOSH in 1980. Area and personal samples were collected and former and current workers were radiographically screened for silicosis. The median concentration of respirable crystalline silica meter. The range was from undetectable amounts of dust to 350 micrograms per cubic meter. Concentrations in the silo and millroom exceeded NIOSH standards. Out of 47 past and present workers, complicated silicosis was diagnosed in 5 of the present workers and 1 of the former workers. All had been exposed to silica prior to 1972 when dirtier industrial processes had been employed in the facility. NIOSH recommends that general housekeeping be made more rigorous, that several leaks be repaired, and that dust concentrations be kept below the NIOSH standard by means of engineering controls. When concentrations exceed the standard respirators should be used. Industrial hygiene monitoring should be performed at least twice a year and medical records should be kept for at least 30 years after the termination of a worker's employment.
