29 CFR 1910.1000(a)(2): An employee's exposure to any substance in Table Z-1, the exposure limit of which is not preceded by a "C", shall not exceed the 8-hour Time Weighted Average given for that substance any 8-hour work shift of a 40-hour work week: a) On April 2, 2021, a Small Parts Finisher employee was exposed to an 8-hour time weighted average (TWA) of 16.6 mg/m^3 for total dust fraction of particulate not otherwise regulated (PNOR), approximately 1.1 times the Permissible Exposure Limit (PEL) of 15 mg/m^3. The exposure level was derived from a sample collected over a 478 minute sampling period with zero exposure assumed for the unsampled period of 2 minutes. b) On April 2, 2021, a Small Parts Finisher employee was exposed to an 8-hour time weighted average (TWA) of 19.7 mg/m^3 for the total dust fraction of PNOR, approximately 1.3 times the Permissible Exposure Limit (PEL) of 15 mg/m^3. The exposure level was derived from a sample collected over a 468 minute sampling period with zero exposure assumed for the unsampled period of 12 minutes. c) On April 2, 2021, a Finisher employee was exposed to an 8-hour time weighted average (TWA) of 16.9 mg/m^3 for the total dust fraction of PNOR, approximately 1.1 times the Permissible Exposure Limit (PEL) of 15 mg/m^3. The exposure level was derived from a sample collected over a 488 minute sampling period with zero exposure assumed for the unsampled period of 0 minutes. d) On April 2, 2021, a Finisher employee was exposed to an 8-hour time weighted average (TWA) of 16.8 mg/m^3 for the total dust fraction of PNOR, approximately 1.1 times the Permissible Exposure Limit (PEL) of 15 mg/m^3. The exposure level was derived from a sample collected over a 488 minute sampling period with zero exposure assumed for the unsampled period of 0 minutes.
