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 January 7, 2021, employees working in the polishing area and the fabrication 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 these employees with medical surveillance: a. A Polisher employee performing granite polishing duties was exposed to an 8-hour TWA for respirable crystalline quartz silica of 104 micrograms per cubic meter air during a 484 minute sampling period. This exposure level exceeded the action limit of 25 micrograms per cubic meter air. b. A Fabricator employee performing granite fabricating duties was exposed to an 8-hour TWA for respirable crystalline quartz silica of 231 micrograms per cubic meter air during a 449 minute sampling period. This exposure level exceeded the action limit of 25 micrograms per cubic meter air. Zero exposure was assumed for the 31 minutes that were not sampled. c. A Polisher employee performing granite polishing duties was exposed to an 8-hour TWA for respirable crystalline quartz silica of 34.4 micrograms per cubic meter air during a 461 minute sampling period. This exposure level exceeded the action limit of 25 micrograms per cubic meter air. Zero exposure was assumed for the 19 minutes that were not sampled.
