Text For Citation: 01 Item/Group: 011C Hazard:

29 CFR 1910.1000(e): To achieve compliance with paragraphs (a) through (d) of this section, administrative or engineering controls were not first determined and implemented whenever feasible. When such controls were not feasible to achieve full compliance, protective equipment or any other protective measures was not used to keep the exposure of employees to air contaminants within the limits prescribed in this section. Any equipment and/or technical measures used for this purpose was not approved for each particular use by a competent industrial hygienist or other technically qualified person. a. MCM Precision Castings, Inc. located in Weston, Ohio: On or about November 20, 2014, the employer did not ensure engineering controls were implemented to protect employees operating the sand blasting cabinet from being overexposed to respirable dust at 289.79 mg/m3 which exceeded the OSHA Permissible Exposure Limit (PEL) of 5 mg/m3 by 5795% and overexposed to crystalline silica dust at 289.79 mg/m3 which exceeded the OSHA Permissible Exposure Limit (PEL) of 0.138 mg/m3 by 2099%. b. MCM Precision Castings, Inc. located in Weston, Ohio: On or about November 20, 2014, the employer did not ensure engineering controls were implemented to protect employees operating the knockout machine from being overexposed to crystalline silica dust at 0.666 mg/m3 which exceeded the OSHA Permissible Exposure Limit (PEL) of 0.385 mg/m3 by 173%. Step 1: Provide effective respiratory protection to and ensure it is 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 or modification/redesign. All proposed control measures shall be approved for each particular use by a competent industrial hygienist or other technically qualified person. 90 day progress reports are required during the abatement period. Step3: Abatement shall have been completed by the implementation of feasible engineering and/or administrative controls upon verification of their effectiveness in achieving compliance. Feasible engineering controls include, but are not limited to ensuring the abrasive blasting cabinet is properly constructed and maintained to ensure dust does not escape the enclosure during any portion of the abrasive blasting operation and to ensure the dust collection system for the knockout machine if functioning according to manufacturers recommendations.
