29 CFR 1910.1000(e): Feasible administrative or engineering controls were not determined and implemented to achieve compliance with the limits prescribed in 29 CFR 1910.1000(a) through (d): a. On or about December 3, 2019, an employee tasked with isolating and blanking the steam booster was exposed to an 8-hour time weighted average (TWA) of 103.9 parts per million (ppm) for carbon monoxide, approximately 2.08 times the Permissible Exposure Limit (PEL) of 50 ppm. The exposure level was derived utilizing a carboxyhemoglobin calculation which utilized medical information to calculate a 15 minute exposure with zero exposure assumed for the remaining period of 465 minutes. b. On or about December 3, 2019, an employee tasked with isolating and blanking the steam booster was exposed to an 8-hour time weighted average (TWA) of 92.8 parts per million (ppm) for carbon monoxide, approximately 1.86 times the Permissible Exposure Limit (PEL) of 50 ppm. The exposure level was derived utilizing a carboxyhemoglobin calculation which utilized medical information to calculate a 15 minute exposure with zero exposure assumed for the remaining period of 465 minutes. The employer did not ensure that employees were not exposed to carbon monoxide above the OSHA PEL of 50 ppm by means of administrative or engineering controls.
