Title: Health-hazard evaluation report HETA 91-092-2190, William Powell Company, Cincinnati, Ohio

In response to a request from the Ohio Department of Health, an evaluation was made of lead (7439921) exposures at the William Powell Company (SIC-3366), Cincinnati, Ohio. The company manufactured brass valves. At the time of the visit there were 44 workers at the foundry. Airborne lead concentrations exceeded the OSHA Permissible Exposure Limit of 50 micrograms/cubic meter for three personal breathing zone samples and constituted a potential hazard to employees working in the pouring and cut off saw areas. Low concentrations of respirable quartz (14808607) were detected. Cadmium (7440439) was also present. The highest concentrations for both the stationary and continuous pouring operations occurred during the transport of the unventilated full ladle. The cumulative aerosol exposures from the continuous operation task were far greater than those from the stationary operation due to the greater amount of time the worker spent doing continuous pouring. The authors conclude that a potential hazard existed from lead levels in the pouring and cut off saw areas. The authors recommend several measures to reduce the exposure levels including a more efficient ventilation system and a redesign of some of the equipment in use.
