Text For Citation: 01 Item/Group: 001B Hazard:
29 CFR 1926.55(b): Feasible administrative or engineering controls were not implemented to reduce employee exposure(s): On or about July 31, 2018, Feasible administrative or engineering controls were not used while employees were engaged in concrete floor cutting with a dual-powered, gasoline and propane, Diamond Products Concrete Saw, model no. CC2500, serial no. 147801. These employees became ill with symptoms of headaches, severe weakness, chest pain, and shortness of breath, which are characteristics of carbon monoxide poisoning. Two employees were subsequently taken to a local hospital and were diagnosed with carbon monoxide poisoning. (a) Guadalupe Hernandez, Laborer/Crew Lead/Foreman, T & S Excavating, Inc. (Employee "A" (Sample S21860)) was exposed to carbon monoxide (CO) during a 160 minute occupational exposure at a mean calculated 433.9 ppm CO level (SAE = 0.127). The %COHb in the employee's blood reached a calculated peak level of 35.3%. Atmospheric pressure, height, weight, activity levels, tobacco smoking behavior, and other factors were taken into account. The 8-hour TWA exposure was 144.6 ppm CO (SAE = 0.125), which is 2.89 times the OSHA PEL of 50 ppm CO. (b) Colin Knight, Laborer, T & S Excavating, Inc. (Employee "B" (Sample S21861)) was exposed to carbon monoxide (CO) during a 160 minute occupational exposure at a mean calculated 481.4 ppm CO level (SAE = 0.111). The %COHb in the employee's blood reached a calculated peak level of 36.4%. Atmospheric pressure, height, weight, activity levels, tobacco smoking behavior, and other factors were taken into account. The 8-hour TWA exposure was 160.5 ppm CO (SAE = 0.114), which is 3.21 times the OSHA PEL of 50 ppm CO.
