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

29 CFR 1910.134(a)(1): When effective engineering controls were not feasible or while they were being instituted, appropriate respirators were not used pursuant to the requirements of this section: On or about November 9, 2022, the employer did not make respiratory protection mandatory for employees working on the D-Man line when employee exposure to concentrations of more than one substance exceeded the permissible exposure limit for the mixture of heavy metals to include inorganic Lead and Cadmium. The mixture has additive toxic effects on the kidneys. The employee was dismantling Cathode Ray Tubes. 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.
