Text For Citation: 01 Item/Group: 006A Hazard:

29 CFR 1910.134(d)(1)(iii): The employer did not identify and evaluate the respiratory hazard(s) in the workplace; including a reasonable estimate of employee exposures to respiratory hazards and identification of the contaminant's chemical state and physical form: On March 6, 2024, the employer failed to evaluate the respiratory hazards in the Pre-Mix and Back Dump production areas where employees were overexposed to Total Dust. Employee exposures to Total Dust exceeded the Permissible Exposure Limit (PEL) of 15 milligrams per cubic meter of air in instances such as, but not limited to: a) On March 6, 2024, a Pre-Mix Lead was exposed to an 8-hour time weighted average (TWA) of 171.1 milligrams of Total Dust per cubic meter of air, approximately 11.4 times the Permissible Exposure Limit (PEL) of 15 milligrams per cubic meter of air. The exposure was derived from samples collected over a 446-minute sampling period, with zero exposure assumed for the unsampled period of 34 minutes. b) On March 6, 2024, a General Labor employee operating on the Bag Line and Back Dump was exposed to an 8-hour time weighted average (TWA) of 24.3 milligrams of Total Dust per cubic meter of air, approximately 1.6 times the Permissible Exposure Limit (PEL) of 15 milligrams per cubic meter of air. The exposure was derived from samples collected over a 443-minute sampling period, with zero exposure assumed for the unsampled period of 37 minutes.
