General Chemistry Calculations
Question:
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
2. Is the worker over-exposed during the duration of the work-shift?
3. What is the Primary concept of hazard recognition and the hierarchy of hazard control?
4. Going through this list, explain how they might be applied to this example to provide potential solutions.
