29 CFR 1926.1153(d)(2)(i): General. The employer shall assess the exposure of each employee who is or may reasonably be expected to be exposed to respirable crystalline silica at or above the action level in accordance with either the performance option in paragraph (d)(2)(ii) or the scheduled monitoring option in paragraph (d)(2)(iii) of this section. (d)(2)(ii) Performance option. The employer shall assess the 8-hour TWA exposure for each employee on the basis of any combination of air monitoring data or objective data sufficient to accurately characterize employee exposures to respirable crystalline silica. (d)(2)(iii)(A) Scheduled monitoring option. The employer shall 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. Where several employees perform the same tasks on the same shift and in the same work area, the employer may sample a representative fraction of these employees in order to meet this requirement. In representative sampling, the employer shall sample the employee(s) who are expected to have the highest exposure to respirable crystalline silica. a) On or about March 18, 2024, at Resilience US, Inc., 8814 Trade Port Drive, Hamilton, Ohio 45011 at fill 5, the employer, EGC, did not assess the exposure of employees to respirable crystalline silica, who were operating a handheld concrete cutting saw using the Hilti DCH 300X electric cutter handheld wet saw with a 12-inch blade while indoors, who was jackhammering concrete slab while indoors, and when assessing a walk-behind concrete saw used indoors by using air monitoring data, objective data, or scheduled air monitoring.
