In response to a request from OSHA, an evaluation was made of possible hazardous exposures to nickel (7440020) and cadmium (7440439) dusts at the Gates Energy Products, Inc. (SIC-3691), Gainesville, Florida. The company manufactured a variety of rechargeable nickel/cadmium cells and batteries for industrial and consumer applications. The plate making areas had approximately 350 production workers and 60 maintenance workers. During a survey in February of 1989, nine of 39 cadmium exposed workers had urine cadmium levels greater than 10 micrograms/gram (microg/g) creatinine. In the survey conducted in October of 1989, 13 of 47 workers in the low and 21 of 49 in the high cumulative airborne cadmium exposure groups had urine cadmium levels greater than 10microg/g creatinine. No consistent differences in urine proteins were observed between the cadmium exposed and nonexposed groups in this analysis of either the February or October 1989 medical surveys. Cumulative airborne cadmium levels did not have a significant relationship with any measure of renal function used in the study. The authors conclude that a significant risk of overexposure to cadmium dust did exist at this facility and that subclinical effects such as significant increases in mean levels of urinary tubular enzymes alanine-aminopeptidase and N-acetyl- glucosaminidase are apparent in cadmium exposed workers with urine cadmium levels above 10microg/g of creatinine compared to those below this level. The authors recommend specific environmental and medical monitoring measures.
