Question

Using the formula CEQ = [(8hr TWA) x 8] / (shift length in hours).... What is the allowable concentration of CO in a 10 hour shift if the 8 hour TWA is 25ppm?

Answer 1

The allowable concentration of CO in a 10-hour shift with an 8-hour TWA of 25 ppm is 20 ppm.

Step-by-step explanation:

The formula CEQ = [(8hr TWA) x 8] / (shift length in hours) is used to calculate the allowable concentration of CO in a given shift. To find the allowable concentration of CO in a 10-hour shift with an 8-hour TWA of 25 ppm, we can substitute the values into the formula.

CEQ = [(25 ppm) x 8] / 10 = 20 ppm

Therefore, the allowable concentration of CO in a 10-hour shift with an 8-hour TWA of 25 ppm is 20 ppm.
