Text For Citation: 01 Item/Group: 005 Hazard:

29 CFR 1910.1053(i)(1)(i): Medical surveillance-(1) General. (i) The employer shall make medical surveillance available at no cost to the employee, and at a reasonable time and place, for each employee who will be occupationally exposed to respirable crystalline silica at or above the action level for 30 or more days per year. On or about February 11, 2025, employees working in the production area were exposed to respirable crystalline silica in excess of the 8-hour time weighted average limit (TWA) for the action limit, and the employer did not provide employees with medical surveillance: a. A fabricator employee was exposed to an 8-hour TWA for respirable crystalline silica of 270 micrograms per cubic meter air during a 353 minute sampling period. This exposure level exceeded the action limit of 25 micrograms per cubic meter air. Zero exposure was assumed for the 127 minutes that were not sampled. b. A sawyer employee was exposed to an 8-hour TWA for respirable crystalline silica of 35 micrograms per cubic meter air during a 378 minute sampling period. This exposure level exceeded the action limit of 25 micrograms per cubic meter air. Zero exposure was assumed for the 102 minutes that were not sampled.
