Text For Citation: 01 Item/Group: 002C Hazard:

29 CFR 1910.1000(e): Feasible administrative or engineering controls were not determined and implemented to achieve compliance with the limits prescribed in 29 CFR 1910.1000(a) through (d): (a) On or about October, 18, 2012 - Finishing, an employee was exposed to an 8-hour time-weighted average level (TWA) of 4.4 milligrams per cubic meters (mg/m3) of silica, crystalline quartz (respirable fraction), 7.5 times the permissible exposure limit (PEL) of 0.588 mg/m3. The sampling was performed for 480 minutes during one shift on October 23, 2012. General methods of abatement include, but are not limited to: 1. Utilizing of wet grinding process. 2. Utilizing engineering controls such as, but not limited to, using grinders equipped with vacuums/dust guards. ABATEMENT SCHEDULE: STEP 1: Effective respiratory protection shall be provided 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 the permissible exposure limits. STEP 2: Submit to the area director a written, detailed plan of abatement outlining a schedule for the implementation of engineering and/or administrative measures to control employee exposure 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: (a) Evaluation of engineering/administrative control options; (b) Selection of optimum control methods and completion of design; (c) Procurement, installation and operation of selected control measures; and (d) Testing and acceptable or modification/redesign of controls. All proposed control measures shall be approved for each particular use by a competent industrial hygienist or other technically qualified person. Thirty - (30) day progress reports are required during the abatement 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.
