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

29 CFR 1910.1026(f)(1)(ii): Painting of aircraft or large aircraft parts was performed; however, the employer did not use feasible engineering and work practice controls to reduce and maintain employee exposures to chromium (VI) to or below 25 micrograms per cubic meter of air: a) The employer does not use feasible engineering and work practice controls to ensure that no employees are exposed to an airborne concentration of chromium(VI) of twenty-five (25) micrograms per cubic meter as an eight (8) hour time weighted average (TWA) while painting aircraft parts. This potential overexposure occurred on 8/12/2014, in the paint booth on the south corner of building 3001, when an employee was exposed to an eight-hour time weighted average concentration of twenty-seven (27) micrograms per cubic meter of chromium(VI) when sampled for 441 minutes. Zero exposure was assumed for the un-sampled 39 minutes. b) The employer does not use feasible engineering and work practice controls to ensure that no employees are exposed to an airborne concentration of chromium(VI) of twenty-five (25) micrograms per cubic meter as an eight (8) hour time weighted average (TWA) while painting aircraft parts. This violation occurred on 12/22/2014, in the paint booth on the south corner of building 3001, when an employee was exposed to an eight-hour time weighted average concentration of twenty-nine (29) micrograms per cubic meter of chromium(VI) when sampled for 87 minutes. Zero exposure was assumed for the un-sampled 393 minutes. c) The employer does not use feasible engineering and work practice controls to ensure that no employees are exposed to an airborne concentration of chromium(VI) of twenty-five (25) micrograms per cubic meter as an eight (8) hour time weighted average (TWA) while painting aircraft parts. This violation occurred on 12/22/2014, in the paint booth on the south corner of building 3001, when an employee was exposed to an eight-hour time weighted average concentration of thirty-four (34) micrograms per cubic meter of chromium(VI) when sampled for 87 minutes. Zero exposure was assumed for the un-sampled 393 minutes.
