General-duty citation text

29 CFR 1910.1027(f)(1)(i): The employer did not implement engineering and work practice controls to reduce and maintain employee exposure to cadmium at or below the permissible exposure limit (PEL):    (a) On or about 11/19/14 - Building 433 baghouse, an employee conducting maintenance work was exposed to an airborne concentration of cadmium dust of approximately 0.042 micrograms/m3 or 8.432 times the PEL. Sampling was conducted on 02/05/15 for 349 minutes. Zero exposure was assumed for the rest of the shift.    (b) On or about 11/19/14 - Building 433 baghouse, an employee conducting maintenance work was exposed to an airborne concentration of cadmium dust of approximately 0.019 micrograms/m3 or 3.712 times the PEL. Sampling was conducted on 02/05/15 for 330 minutes. Zero exposure was assumed for the rest of the shift.    (c) On or about 11/19/14 - Building 433 baghouse, an employee conducting maintenance work was exposed to an airborne concentration of cadmium dust of approximately 0.140 micrograms/m3 or 27.567 times the PEL. Sampling was conducted on 02/05/15 for 337 minutes. Zero exposure was assumed for the rest of the shift.    Step 1 - Effective respiratory protection shall be provided to and used by exposed employees as an interim protective measure until feasible engineering and/or administrative controls can be implemented or whenever such controls fail to reduce employee exposure to within permissible exposure limits.    Step 2  - A written detailed plan of abatement shall be submitted to the Area Director outlining a schedule for the implementation of engineering and/or administrative measures to control employee exposures to hazardous substances as referenced in this citation. This plan shall include, at a minimum, target dates for the following actions which must be consistent with the abatement dates required by this citation:                         (1)  Evaluation of engineering/administrative control options;                       (2)  Selection of optimum control methods and completion of design;                       (3)  Procurement, installation and operation of selected control measures;                       (4)  Testing and acceptance.     All proposed control measures shall be approved for each particular use by a competent industrial hygienist or other technically qualified person.  30-day progress reports are required during the evaluation period.    Step 3 -  Abatement shall have been completed by the implementation of feasible engineering and / or administrative controls upon verification of their effectiveness in achieving compliance.
