29 CFR 1910.1053(f)(1): The employer did not use engineering and work practice controls to reduce and maintain employee exposure to respirable crystalline silica to or below the PEL, unless the employer can demonstrate that such controls are not feasible: On or about April 27, 2022, and days prior, employees performed work on the shop floor while being exposed to airborne concentration of respirable crystalline quartz silica above the 8-hour time weighted average of 50 micrograms per cubic meter of air (ug/m^3)., without effective work practice controls and/or engineering controls. a) On or about April 27, 2022, the employee operating Squisher #2 was exposed to respirable crystalline silica (RCS) at an 8-hour time weighted average (TWA) of 59 micrograms per cubic meter of air, approximately 1.18 times the limit of 50 micrograms per cubic meter of air. The sample was collected during a 407 minute sampling period, and exposure calculations include a zero increment for the 73 minutes not sampled. b) On or about April 27, 2022, the employee operating the pallet line was exposed to respirable crystalline silica (RCS) at an 8-hour time weighted average (TWA) of 80 micrograms per cubic meter of air, approximately 1.6 times the limit of 50 micrograms per cubic meter of air. The sample was collected during a 395 minute sampling period, and exposure calculations include a zero increment for the 85 minutes not sampled.
