Unit VII

Imagine that you are a safety officer, and you have been asked to recommend a type of ventilation system for your company. Which one would you choose, and why?

Unit VIII  

OSHA allows respirator fit testing to be performed using either qualitative fit testing (QLFT) methods or quantitative fit testing (QNFT) methods that are specified in Appendix A of 29 CFR 1910.134. Discuss the fit testing methods with which you are familiar and which methods you prefer to use. If you have never been fit tested or performed fit testing, read Appendix A and discuss which of the methods you believe would be the easiest to perform. Give the reasons for your choice.
