29 CFR 1910.1027(c): The employer did not ensure that no employee was exposed to an airborne concentration of cadmium in excess of five micrograms per cubic meter of air (5ug/m3), calculated as an eight-hour time-weighted average (TWA): (a)Hill Air Force Base, at 7290 Weiner Street, Hill Air Force Base, UT: On 3/3/11, Hill Air Force Base did not ensure that no employee was exposed to an airborne concentration of cadmium in excess of five micrograms per cubic meter of air (5ug/m3), calculated as an eight-hour time-weighted average (TWA). One employee abrasively blasted aircraft parts in Building 507J4. The metal treatment contained cadmium. This process generated cadmium dust. On 3/3/11 one employee was exposed to cadmium at a concentration greater than the 8 hour Time Weighted Average (TWA) Permissible Exposure Limit (PEL) of 0.005 mg/m3. The employee was exposed to cadmium at a concentration of 0.0663 mg/m3 as an 8 hour TWA. This is 13.27 times the PEL. Air monitoring was conducted for 374 minutes. (b)Hill Air Force Base, at 7290 Weiner Street, Hill Air Force Base, UT: On 3/3/11, Hill Air Force Base did not ensure that no employee was exposed to an airborne concentration of cadmium in excess of five micrograms per cubic meter of air (5ug/m3), calculated as an eight-hour time-weighted average (TWA). One employee abrasively blasted generators and small parts in Building 843B1. The metal treatment contained cadmium. This process generated cadmium dust. On 3/3/11 one employee was exposed to cadmium at a concentration greater than the 8 hour Time Weighted Average (TWA) Permissible Exposure Limit (PEL) of 0.005 mg/m3. The employee was exposed to cadmium at a concentration of 0.1871 mg/m3 as an 8 hour TWA. This is 37.40 times the PEL. Air monitoring was conducted for 265 minutes.
