Module 5. Quiz
Please answer the following question below. Please submit this as a word document.
1. Assume we have a group of workers in a factory and many of them already have a respiratory
illness. We want to design a study to evaluate if exposure to some specific factor relates to the
illnesses. What study design should we use and how would we conduct the study?
2. Imagine that an industrial hygienist and a safety engineer identify that there is an exposure to
a new chemical that represents a major health hazard in your factory. They immediately
recommend that all of the employees exposed to the chemical use a specific and appropriate type
of PPE. Is this the only thing they should do? What other control measure should we consider
and potentially implement as management of the factory? Why?
3. What is indicated by a LD-50? What is indicated by ED-50? What might it mean if the ED50 equals the LD-50?
