Abstract
The occupational health program for lead (7439921) exposed workers at an industrial lead smelting site (SIC-3332) was evaluated during July 1977 by NIOSH. NIOSH reviewed blood lead data gathered since the beginning of the year, scanned the medical records of all workers who had received chelation therapy since July 1976, read consulting reports, and interviewed officials and employees in the company. Out of 500 lead exposed workers, 123 had blood lead concentrations that exceeded 70 micrograms per 100 milliliters (ml) during the first quarter of 1977 and 142 had concentrations that exceeded 70 micrograms per 100ml during the second quarter. Several areas of the facility had ambient lead concentrations that exceeded the OSHA standard of 200 micrograms per cubic meter. NIOSH concludes that the company should continue its present medical monitoring program. However, it is recommended that asymptomatic individuals not receive chelation therapy and that oral chelation therapy be carried out only on the advice of an employee's private physician. Rigorous hygienic practices should be emphasized including the discouragement of smoking in work areas. Respirators should be worn in areas of high lead concentration.
