The %COHb in the employees' blood reached a calculated peak level of 37.9%. Atmospheric pressure, height, weight, activity levels, tobacco smoking behavior, and other factors were taken into account. The 8-hour TWA exposure was 127.9 ppm CO (SAE = 0.116), which is 2.56 times the OSHA PEL of 50 ppm CO.  The carbon monoxide level was derived from blood carboxyhemoglobin levels.  b)On or about January 17, 2025, an employee of Litteken Construction Company, LLC  was exposed to carbon monoxide (CO) during a 420 minute occupational exposure at a mean calculated 95.9 ppm CO level (SAE = 0.134).

The 8-hour TWA exposure was 84.0 ppm CO (SAE = 0.133), which is 1.68 times the OSHA PEL of 50 ppm CO.  The carbon monoxide level was derived from blood carboxyhemoglobin levels.

Any equipment and technical measures used for this purpose must first be approved for each particular use by a competent industrial hygienist or other technically qualified person. Whenever respirators are used, their use shall comply with �1926.103.
