1.The TLV for carbon monoxide is 35ppm. Define the terms TLV and ppm and calculate them for the following example:

A mechanic in an automotive repair shop is exposed to the following carbon monoxide levels over an 8 hour shift.
2 hours @ 34 ppm
5 hours @ 40 ppm
1 hour @ 20 ppm

Is the worker over-exposed during the duration of the work-shift?

What is the Primary concept of hazard recognition and the hierarchy of hazard control?
