At a work place, an employee is exposed to three chemicals during an eight hour shift as follows:
| Chemical | Actual Exposure (ppm) | PEL (ppm) |
| A | 50 | 250 |
| B | 30 | 150 |
| C | 200 | 800 |
What is the additive effects of multiple chemicals exposed during 8-hour period? _________
Is the worker required to wear a PPE? ______
Homework Answers
Additive effects of multiple chemicals = (C1÷L1+C2÷L2)+. . .(Cn÷Ln) =(50/250)+(30/150)+(200/800) =0.65
As additive effects of multiple chemicals is less than 1, so it is within the safe range and thus no need to wear a PPE.
