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

29 CFR 1910.1025(e)(1)(i): For any employees exposed to lead above the permissible exposure limit for more than 30 days per year where engineering and work practice controls (including administrative controls) were feasible but did not reduce the employees' exposure to or below the permissible exposure limit the employer did not use engineering and/or work practice controls to reduce exposures to the lowest feasible level: a) In the Production Area - On October 21, 2015, an employee performing the Disa pouring operation was exposed to lead at a level of 295 micrograms per cubic meter of air over a 10-hour workshift, which is in excess of the Permissible Exposure Limit (PEL) of 40 micrograms per cubic meter of air for that workshift. All feasible engineering, workpractice or administrative controls were not implemented to reduce that exposure to within the PEL or to the lowest achievable level. Abatement certification and documentation required within 10 days after abatement date. The certification shall include a statement that abatement is complete, the date and method of abatement, and state that employees and their representatives were informed of this abatement. Abatement documentation shall include documents demonstrating that abatement is complete, such as evidence of the purchase or repair of equipment, photographic or video evidence of abatement or other written records. Feasible means of abatement include, but are not limited to the following: 1. Install local exhaust ventilation over the ladle to move along the hoist track in order to capture the lead fume escaping the pour ladle. 2. Cover ALL of the dross pot containers in order to contain the fumes liberated from the alloy dross from the furnaces and the pour ladle. 3. Hang an overlapped transparent PVC curtain from the 3-4 feet above the head of the Disa Shaker Operator down to about 1-foot below the shaker mechanisms around the perimeter of each shaker station in order to prevent fugitive leaded pour ladle fumes from being drawn over to the Disa Shaker Operator's breathing zone by the Disa shaker exhaust ventilation, leaving the opening to the Disa shaker's exhaust ventilation open. 4. Have the current ventilation system's effectiveness, duct capture velocities, and ventilation system efficiencies evaluated by an outside engineering firm that specializes in toxic fume and combustible dust ventilation engineering in order to develop a ventilation system streamlining and efficiency improvement plan. 5. Hang an overlapped transparent PVC curtain between the operator and the Cut Off Saw Wheel in order to deflect the cut off tailings from the Operator's breathing zone, install focused local exhaust ventilation on each side of the Cut Off Saw Wheel in order to collect the cut off tailings, and/or place a transparent isolation barrier between the 2 Cut Off Stations to prevent cross-contamination from the cut off tailings. 6. Hang an overlapped transparent PVC curtain from the 3-4 feet above the grinding belt to about 1-foot below the grinding belt around the entire perimeter of each grinding station in order to prevent cross-contamination of the grind tailings between grinders and/or install more focused local exhaust ventilation at the point of operation on the grinding belt in order to collect the grind tailings. 7. Establish and enforce the work practice control of regular pour ladle lid and fiberglass wool replacement to provide better fume seals, and/or establish and enforce the work practice control of keeping the fugitive pour ladle fume out of the pourer's breathing zone while they raise or lower the pour ladle on the hoist.
