Question
46. A plant's atmosphere has the following concentrations of contaminants for the times shown:| Diethylamine | Phenol | Methyl alcohol | |
| (PEL 25 ppm) | (PEL 5 ppm) | (PEL 200 ppm) | |
| 8:00 AM - 10:00 AM | 4 ppm | none | 10 ppm |
| 10:00 AM - 11:00 AM | 6 ppm | none | 30 ppm |
| 11:00 AM - noon | 9 ppm | 1 ppm | 50 ppm |
| noon - 4:00 PM | 12 ppm | 3 ppm | 80 ppm |
Perform all calculations to determine whether action levels and PELs for the contaminants and their mixture are exceeded. SHOW YOUR CALCULATIONS.
