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. On or about February 24, 2017, an employee working as the VTD helper was exposed to lead at an 8-hour Time-Weighted Average (TWA) of 60.32 µg/m3 during the 381 minute sampling period. This is 1.207 times the Permissible Exposure Limit (PEL) of 50 µg/m3. Exposure calculations include a zero exposure increment for the 99 minutes not sampled. b. On or about February 24, 2017, an employee working on the cast floor in CBCF was exposed to lead at an 8-hour Time-Weighted Average (TWA) of 77.6 µg/m3 during the 405 minute sampling period. This is 1.553 times the Permissible Exposure Limit (PEL) of 50 µg/m3. Exposure calculations include a zero exposure increment for the 75 minutes not sampled. c. On or about February 24, 2017, an employee working on the cast floor in CBCF was exposed to lead at an 8-hour Time-Weighted Average (TWA) of 84.38 µg/m3 during the 405 minute sampling period. This is 1.688 times the Permissible Exposure Limit (PEL) of 50 µg/m3. Exposure calculations include a zero exposure increment for the 75 minutes not sampled. d. On or about February 24, 2017, an employee working on ladle deck in CBCF was exposed to lead at an 8-hour Time-Weighted Average (TWA) of 70.18µg/m3 during the 401 minute sampling period. This is 1.404 times the Permissible Exposure Limit (PEL) of 50 µg/m3. Exposure calculations include a zero exposure increment for the 79 minutes not sampled. e. On or about February 24, 2017, an employee working on ladle deck in CBCF was exposed to lead at an 8-hour Time-Weighted Average (TWA) of 71.36µg/m3 during the 403 minute sampling period. This is 1.427 times the Permissible Exposure Limit (PEL) of 50 µg/m3. Exposure calculations include a zero exposure increment for the 77 minutes not sampled. f. On or about February 24, 2017, an employee operating Crane 422 in the melt shop was exposed to lead at an 8-hour Time-Weighted Average (TWA) of 151.7 µg/m3 during the 455 minute sampling period. This is 3.03 times the Permissible Exposure Limit (PEL) of 50 µg/m3. Exposure calculations include a zero exposure increment for the 25 minutes not sampled. g. On or about February 24, 2017, an employee working in 2nd Steel Pour in the melt shop was exposed to lead at an 8-hour Time-Weighted Average (TWA) of 611.9 µg/m3 during the 445 minute sampling period. This is 12.238 times the Permissible Exposure Limit (PEL) of 50 µg/m3. Exposure calculations include a zero exposure increment for the 35 minutes not sampled. Engineering controls were not utilized to reduce employee exposure to lead below the OSHA permissible exposure limit.
