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 parts per million (ppm): On or about November 26, 2023, at the YMCA located at 1115 East US 54, Andover, Kansas, an employee was exposed to Carbon Monoxide (CO) levels above the eight-hour time-weighted average (8-hour TWA) permissible exposure limit (PEL) of 50 parts carbon monoxide per million parts of air (50 ppm carbon monoxide). The employee was exposed to an average of 1888.8 parts carbon monoxide per million parts of air (SAE = 0.090) during an estimated time of 300 minutes of exposure. The calculated 8-hour time Weighted-Average exposure of 1180.5 parts carbon monoxide per million parts of air (SAE= 0.089) as determined by the employee's Carboxyhemoglobin (%COHb) medical blood gas measurement taken following the employee's fatal exposure to carbon monoxide at the worksite. The exposure was 23.61 times the PEL for Carbon Monoxide.
