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

29 CFR 1910.1053(d)(3)(i): The employer did not perform initial monitoring to assess the 8-hour TWA exposure for each employee on the basis of one or more personal breathing zone air samples that reflect the exposures of employees on each shift, for each job classification, in each work area: a) Brick Face Saw Area; On or about August 31, 2023, and at times prior thereto, the employer failed to assess the employee cutting brick faces to determine their 8-hour TWA exposure. An employee operating the brick face saw was exposed to respirable crystalline silica hazards at 326 micrograms per cubic meter which is approximately 6.52 times the permissible exposure level of 50 micrograms per cubic meter. Results were based on a 499-minute sampling period.
