Text For Citation: 01 Item/Group: 007 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 is to make this determination in accordance with either paragraph (d)(2), the scheduled monitoring option, or paragraph (d)(3), the performance-oriented option. Mercury Products, Corp. in Schaumburg, IL, did not initially determine the 8-hour time-weighted average exposure levels for employees exposed to hexavalent chromium during processing or tasks performed on stainless steel, such as welding. a) On October 9, 2014, a Mercury Products, Corp. employee conducting MIG welding on stainless steel parts was determined to have an 8-hour time-weighted average exposure level to hexavalent chromium of 0.0008 mg/M3 during the 406-minute sampling period, exceeding the criterion limit of 0.0005 mg/M3 which triggers the requirement for initial monitoring. Zero exposure was assumed for the unsampled time period of 74 minutes. In accordance with 29 CFR 1903.19(d), abatement certification is required for this violation (using the CERTIFICATION OF CORRECTIVE ACTION WORKSHEET), and in addition, documentation demonstrating that abatement is complete must be included with your certification. This documentation may include, but is not limited to, evidence of the purchase or repair of the equipment, photographic or video evidence of abatement, or other written records.
