The TLV for carbon monoxide is 25ppm according to the Ministry of Labour for Ontario. Consider the following example:

A mechanic in an automotive repair shop is exposed to the following carbon monoxide levels over an 8 hour shift.

1. 2 hours @ 34 ppm

2. 5 hours @ 40 ppm

3. 1 hour @ 20 ppm

Is the worker over-exposed during the duration of the work-shift? (To complete the calculation, add up the doses for every hour of the shift and divide by 8 hours to determine average exposure.)
