| Abstract |
In July 1973 OSHA cited this plant for violations of the air-borne lead standard. At OSHA's request, NIOSH arranged for a medical evaluation of the worker's current health status. Medical examinations were carried out on workers in this railroad bearing foundry in November 1976. There were 95 workers screened using a ZPP test. Fifty-two men who worked at high-risk jobs or had a ZPP value equal to or greater than 90 micrograms were examined by history, physical and laboratory tests. Eighty-five percent (85%) of these had lead levels greater than 40 micrograms per 100 ml of blood, and over 20% had levels greater than 60 micrograms. Thirty-five percent (35%) had abnormally elevated blood pressures and a significant number had abnormalities of the urine and other parameters of renal function including BUN. In summary, this railroad bearing foundry, under abatement, and with a program apparently aimed at decreasing the risk to workers of lead intoxication was found to have a number of workers with blood lead over 60 micrograms/100 ml, zinc protoporphyrin over 90 micrograms FEP/100 ml, abnormalities of renal function as shown by abnormal urinalyses or BUN's over 21 mg%, or elevated blood pressures. It appeared on the walk-through that lead and dust possibly containing lead were present in excessive quantities in the work area. |
