29 CFR 1910.1000(e): Feasible administrative or engineering controls were not determined and implemented to achieve compliance with the limits prescribed in 29 CFR 1910.1000(a) through (d): On or about November 9, 2022, employees working the D-Man line exposures were exposed in excess of the permissible exposure limit for the mixture for Lead and Cadmium and administrative or engineering controls were not implemented to decrease employees exposures below the computation formula as specified in in 29 CFR 1910.1000(d)(2)(i). (a) The employer did not ensure that employee exposure to concentrations of more than one substance did not exceed the permissible exposure limit for the mixture of heavy metals to include inorganic Lead and Cadmium. The mixture has additive toxic effects on the kidney. This violation occurred on November 9, 2022, where the employee was dismantling Cathode Ray Tubes on the D-Man line. The employee was exposed to inorganic Lead at an 8-hour time weighted average (TWA) of 0.00778 milligrams per cubic meter (mg/m3) of air, approximately 0.155 times the permissible exposure limit (PEL) of 0.05 mg/m3; and Cadmium at an 8-hour TWA of 0.00807 mg/m3 of air, approximately 1.61 times the PEL of 0.005 mg/m3. The exposure concentration was approximately 1.63 times the permissible 8-hour TWA concentration for the mixture. Sampling was performed for 467 minutes. Zero exposure was assumed for the 13 minute period not sampled. (b) The employer did not ensure that employee exposure to concentrations of more than one substance did not exceed the permissible exposure limit for the mixture of heavy metals to include inorganic Lead and Cadmium The mixture has additive toxic effects on the kidney. This violation occurred on November 9, 2022, where the employee was dismantling Cathode Ray Tubes on the M10 line and D-Man line. The employee was exposed to inorganic Lead at an 8-hour time weighted average (TWA) of 0.0284 milligrams per cubic meter (mg/m3) of air, approximately 0.568 times the permissible exposure limit (PEL) of 0.05 mg/m3; and Cadmium at an 8-hour TWA of 0.0054 mg/m3 of air, approximately 1.082 times the PEL of 0.005 mg/m3. The exposure concentration was approximately 1.54 times the permissible 8-hour TWA concentration for the mixture. Sampling was performed for 465 minutes. Zero exposure was assumed for the 15 minute period not sampled.
