In response to a request from Standard Industries (SIC-3691), San Antonio, Texas, an investigation was conducted to determine if improved engineering controls reduced employee lead (7439921) exposures. Standard Industries manufactured lead acid batteries in a 300,000 square foot facility. Approximately 150 persons were employed on site. The process was typical of such industries but the facility was not highly automated as the batteries produced were often of unique sizes. Personal breathing zone samples collected in various locations throughout the facility exceeded the OSHA 50 micrograms/cubic meter (microg/m3) criterion. The highest personal breathing zone exposures were found in the plate pasting operations, ranging from 68 to 495microg/m3. In the first assembly and pouching areas, exposures ranged from 15 to 418microg/m3 and from 31 to 77microg/m3, respectively. Lead was consistently found in wipe samples from cafeteria table tops. Hand wipe samples showed significantly increased amounts of lead from employees finishing lunch compared to wipes prior to entering the lunchroom. A consistent daily increase in saliva lead was monitored. The authors conclude that lead exposures exceeded the OSHA limit, even though engineering controls were appropriate. Work practices and housekeeping issues were identified which may have contributed to overexposures. Modifications to some engineering controls were suggested.
