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: 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, the employer did not implement engineering and work practice controls (including administrative controls), were not implemented to reduce and maintain employee exposure to lead: (a) Engineering and work practice controls were not effectively used to reduce and maintain exposures to lead: 10. On March 1, 2018, a Utility worker on COS Line 6 was exposed to lead at an 8-hour time weighted average of 0.5672 mg/m3, approximately 11.34 times the permissible exposure limit of 0.050 mg/m3. This limit is established to prevent Central Nervous System (CNS), kidney, blood forming and reproductive system damage. The air samples were collected over 438 minutes. Exposure calculations include a zero increment for the 42 minutes not sampled. Feasible and acceptable abatement methods, among others, to correct these hazards include, but are not limited to: * Improve local exhaust systems by ensuring that down draft tables or slotted hoods are maintained at recommended air flow rates. During the inspection air flow at the following ventilation units was found to be below the recommended rates (800 to 1200 feet per minute) at the exhaust port: - On March 1, 2018, at COS Line 6 the air velocity at the exhaust port of the downdraft exhaust hood at the Re-Work Station was approximately 80 fpm. * Provide improved ventilation for the Mixing Stations on the 2nd Level of Pasting. * Provide properly functioning vacuum lines for the Mixing Stations on the 2nd Level of Pasting. * Provide improved ventilation for the Grob Band Saw which is used to cut strap (lead alloy) and to cut through batteries on COS Line 6. * Provide improved separation of lead contaminated waste from general plant waste in COS Line 6.
