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 concentration of 50 ppm: 1) On or about January 2, 2018, the employer did not ensure that employee(s) exposed to carbon monoxide did not exceed 50 ppm for an 8-hour time weighted average (TWA). An employee sorting boards in the saw room was exposed to carbon monoxide at an 8-hour TWA of 513.4 ppm, approximately 10.27 times the permissible exposure limit of 50 ppm. The carbon monoxide level was derived from blood carboxyhemoglobin levels. 2) On or about January 2, 2018, the employer did not ensure that employee(s) exposed to carbon monoxide did not exceed 50 ppm for an 8-hour time weighted average (TWA). An employee disassembling pallets in the shop area was exposed to carbon monoxide at an 8-hour TWA of 344.4 ppm, approximately 6.89 times the permissible exposure limit of 50 ppm. The carbon monoxide level was derived from blood carboxyhemoglobin levels. 3) On or about January 2, 2018, the employer did not ensure that employee(s) exposed to carbon monoxide did not exceed 50 ppm for an 8-hour time weighted average (TWA). An employee sorting boards in the saw room was exposed to carbon monoxide at an 8-hour TWA of 214.9 ppm, approximately 4.30 times the permissible exposure limit of 50 ppm. The carbon monoxide level was derived from blood carboxyhemoglobin levels. 4) On or about January 4, 2018, the employer did not ensure that employee(s) exposed to carbon monoxide did not exceed 50 ppm for an 8-hour time weighted average (TWA). An employee sorting boards in the saw room was exposed to carbon monoxide at an 8-hour TWA of 113.4 ppm, approximately 2.27 times the permissible exposure limit of 50 ppm. The carbon monoxide level was derived from blood carboxyhemoglobin levels. 5) On or about January 4, 2018, the employer did not ensure that employee(s) exposed to carbon monoxide did not exceed 50 ppm for an 8-hour time weighted average (TWA). An employee assembling pallets in the shop area was exposed to carbon monoxide at an 8-hour TWA of 235.8 ppm, approximately 4.72 times the permissible exposure limit of 50 ppm. The carbon monoxide level was derived from blood carboxyhemoglobin levels. 6) On or about January 4, 2018, the employer did not ensure that employee(s) exposed to carbon monoxide did not exceed 50 ppm for an 8-hour time weighted average (TWA). An employee assembling pallets in the shop area was exposed to carbon monoxide at an 8-hour TWA of 225 ppm, approximately 4.50 times the permissible exposure limit of 50 ppm. The carbon monoxide level was derived from blood carboxyhemoglobin levels. 7) On or about January 4, 2018, the employer did not ensure that employee(s) exposed to carbon monoxide did not exceed 50 ppm for an 8-hour time weighted average (TWA). An employee disassembling pallets in the shop area was exposed to carbon monoxide at an 8-hour TWA of 214.1 ppm, approximately 4.28 times the permissible exposure limit of 50 ppm. The carbon monoxide level was derived from blood carboxyhemoglobin levels. 8) On or about January 4, 2018, the employer did not ensure that employee(s) exposed to carbon monoxide did not exceed 50 ppm for an 8-hour time weighted average (TWA). An employee sorting boards in the saw room was exposed to carbon monoxide at an 8-hour TWA of 174.6 ppm, approximately 3.49 times the permissible exposure limit of 50 ppm. The carbon monoxide level was derived from blood carboxyhemoglobin levels. 9) On or about January 4, 2018, the employer did not ensure that employee(s) exposed to carbon monoxide did not exceed 50 ppm for an 8-hour time weighted average (TWA). An employee sorting boards in the saw room was exposed to carbon monoxide at an 8-hour TWA of 70.9 ppm, approximately 1.42 times the permissible exposure limit of 50 ppm. The carbon monoxide level was derived from blood carboxyhemoglobin levels. 10) On or about January 4, 2018, the employer did not ensure that employee(s) exposed to carbon monoxide did not exceed 50 ppm for an 8-hour time weighted average (TWA). An employee sorting boards in the saw room was exposed to carbon monoxide at an 8-hour TWA of 107.2 ppm, approximately 2.14 times the permissible exposure limit of 50 ppm. The carbon monoxide level was derived from blood carboxyhemoglobin levels. 11) On or about January 4, 2018, the employer did not ensure that employee(s) exposed to carbon monoxide did not exceed 50 ppm for an 8-hour time weighted average (TWA). An employee working in the front office was exposed to carbon monoxide at an 8-hour TWA of 108.0 ppm, approximately 2.16 times the permissible exposure limit of 50 ppm. The carbon monoxide level was derived from blood carboxyhemoglobin levels. Abatement documentation is required for this item in accordance with the requirements of 29 CFR 1903.19(d).
