Text For Citation: 01 Item/Group: 006B 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): On September 19, 2019, the 1212 Grinder (North Side) was exposed to an airborne concentration of 1.4327 milligrams per cubic meter of copper dust, which is 1.4 times the 8 hour Time Weighted Average permissible exposure limit concentration of 1 milligram per cubic meter. The sample was taken over 428 minutes. Zero exposure was assumed for the remaining 52 minutes. General methods of control applicable in these circumstances include, but are not limited to, the following: 1. Reevaluate the efficacy of the ventilation provided for the 1212 Grinder (North side). Ensure that the ventilation meets or exceeds the most current recommendations outlined in the Handbook of the American Society of Heating, Refrigerating and Air Conditioning Engineers (ASHRAE), and/or the American Foundrymen's Society (AFS) Foundry Ventilation Manual. 2. Research administrative controls to reduce the amount of copper dust released into the work environment. This may include addressing the pile up of copper dust on the work rest that can be deflected back to the operator. 3. Research administrative controls to reduce employees 8 hour exposures. This may include job rotation to other positions or tasks with less or no exposure to copper dust. Disclaimers: 1. The employer is not limited to the abatement methods suggested by OSHA; 2. The methods explained are general and may not be effective in all cases; and 3. The employer is responsible for selecting and carrying out an effective abat Abatement Schedule STEP 1: Effective respiratory protection shall be provided and used by exposed employees as an interim protective measure until feasible engineering controls can be implemented or whenever such controls fail to reduce employee exposures 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 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 abatement dates required by this citation: 1. Evaluation of engineering control options; 2. Selection of optimum control methods and completion of design; 3. Procurement, installation, and operation of selected control measures; and 4. Testing and acceptance or modification/redesign of controls. NOTE: All proposed control measures shall be approved for each particular use by a competent industrial hygienist or other technically qualified person. STEP 3: Abatement shall have been completed by the implementation of feasible engineering controls upon verification of their effectiveness in achieving compliance.
