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

29 CFR 1910.1026(d)(1): The employer with a workplace or work operation covered by this standard did not determine the 8-hour time-weighted average exposure for each employee exposed to chromium (VI): The employer did not perform initial monitoring to determine the 8-hour TWA exposure to hexavalent chromium for the employee that operates the plasma cutter where stainless steel is cut into components used in fabrication. On August 4, 2014, the plasma cutter operator was exposed to chromium (VI) at an 8-hour time-weighted average of 10.5 micrograms per cubic meter of air, approximately 2.1 times the Permissible Exposure Limit (PEL) of 5 micrograms per cubic meter of air; This limit has been established to prevent an increased risk of cancer, irritation, and sensitization to the lungs, throat, nose, eyes, and skin. The sample was collected over a 434 minute sampling period, with an assumed exposure of zero for the remaining 46 minutes. Abatement documentation is required for this item in accordance with the requirements of 29 CFR 1903.19(d).
