29 CFR 1910.1000(a)(2): Employee(s) were exposed to an airborne concentration of carbon monoxide listed in Table Z-1 in excess of the 8 hour Time Weighted Average (TWA) concentration of 50 parts per million (ppm): a) Valley Services, Inc., Cornelia, GA - On or about July 5, 2019, an employee cooking on a gas powered kettle was exposed to carbon monoxide at a TWA of 196.9 ppm, 3.9 times the PEL of 50 ppm. The exposure was derived from the percent carboxyhemoglobin (%COHb) in the employee's blood that reached a calculated peak level of 44.3% during a 120 minute occupational exposure at a mean calculated 787.5 ppm CO level (SAE =0.169). Atmospheric pressure, height, weight, activity levels, tobacco smoking behavior, and other factors were taken into account. b) Valley Services, Inc., Cornelia, GA - On or about July 5, 2019, an employee assisting in the kitchen while food was cooking on a gas powered kettle was exposed to carbon monoxide at a TWA of 123.1 ppm, 2.46 times the PEL of 50 ppm. The exposure was derived from the percent carboxyhemoglobin (%COHb) in the employee's blood that reached a calculated peak level of 39.4% during a 90 minute occupational exposure at a mean calculated 656.6 ppm CO level (SAE =0.169). Atmospheric pressure, height, weight, activity levels, tobacco smoking behavior, and other factors were taken into account. c) Valley Services, Inc., Cornelia, GA - On or about July 5, 2019, an employee assisting in the kitchen while food was cooking on a gas powered kettle was exposed to carbon monoxide at a TWA of 118.8 ppm, 2.38 times the PEL of 50 ppm. The exposure was derived from the percent carboxyhemoglobin (%COHb) in the employee's blood that reached a calculated peak level of 32% during a 90 minute occupational exposure at a mean calculated 633.5 ppm CO level (SAE =0.169). Atmospheric pressure, height, weight, activity levels, tobacco smoking behavior, and other factors were taken into account.
