Text For Citation: 01 Item/Group: 001A Hazard:

29 CFR 1910.1000(d)(2)(i): Employees were exposed to a mixture of contaminants listed in Subpart Z where the equivalent exposure formulas exceeded the unity of one. On May 5, 2015 in the Dehusker process area: a. An employee performing required duties at the bottom belt "magnet" position was exposed to a mixture of cadmium and lead that exceeded the calculated cumulative exposure limit prescribed by 29 CFR 1910.1000(d). The employee was exposed to 8-hour time weighted averages of 20.08 micrograms lead per cubic meter air and 14.06 micrograms cadmium per cubic meter air during the 366 minutes sampled. Zero exposure was assumed for the 114 minutes not sampled. This exposure represents 3.05 times the cumulative exposure limit for this mixture. Cadmium and Lead, among other hazards, may act in an additive fashion to affect the kidneys. b. An employee performing required duties at the bottom belt sorting position was exposed to a mixture of cadmium and lead that exceeded the calculated cumulative exposure limit prescribed by 29 CFR 1910.1000(d). The employee was exposed to 8-hour time weighted averages of 19.21 micrograms lead per cubic meter air and 13.94 micrograms cadmium per cubic meter air during the 366 minutes sampled. Zero exposure was assumed for the 114 minutes not sampled. This employee exposure represents 3.164 times the cumulative exposure limit for this mixture. Cadmium and Lead, among other hazards, may act in an additive fashion to affect the kidneys. c. An employee performing required duties at the bottom belt sorting position was exposed to a mixture of cadmium and lead that exceeded the calculated cumulative exposure limit prescribed by 29 CFR 1910.1000(d). The employee was exposed to an 8-hour time weighted average of 20.29 micrograms lead per cubic meter air and 13.16 micrograms cadmium per cubic meter air during the 359 minute sampling period. Zero exposure was assumed for 121 minutes not sampled. This employee exposure level represents approximately 3.08 the cumulative exposure limit for this mixture. Cadmium and Lead, among other hazards, may act in an additive fashion to affect the kidneys.
