Text For Citation: 01 Item/Group: 003B Hazard:

29 CFR 1910.1053(f)(1):The employer did not utilize engineering and work practice controls to reduce and maintain employee exposure to respirable crystalline silica to or below the PEL: a) C/D Degating Area; the employer exposed an employee to an 8-hour time-weighted average concentration of respirable crystalline silica at 150.0 micrograms per cubic meter of air (mcg/m), or 2.99 times the permissible exposure limit (PEL) of 50 mcg/m. The sampling was performed during one shift on September 13, 2023, for 480 minutes. The employer did not ensure engineering and administrative controls reduced employee's exposure below the PEL. b) Cell-19 Area; the employer exposed an employee to an 8-hour time-weighted average concentration of respirable crystalline silica at 110.0 micrograms per cubic meter of air (mcg/m), or 2.3 times the permissible exposure limit (PEL) of 50 mcg/m. The sampling was performed during one shift on September 13, 2023, for 480 minutes. The employer did not ensure engineering and administrative controls reduced employee's exposure below the PEL. c) C/D Degating Area; the employer exposed an employee to an 8-hour time-weighted average concentration of respirable crystalline silica at 120.0 micrograms per cubic meter of air (mcg/m), or 2.40 times the permissible exposure limit (PEL) of 50 mcg/m. The sampling was performed during one shift on September 13, 2023, for 480 minutes. The employer did not ensure engineering and administrative controls reduced employee's exposure below the PEL.
