1) Discuss the difference between intrinsic safety and fail-safe design. Provide two examples of each. Which would be preferred under the hierarchy of controls?
2) Explain the difference between administrative programs and administrative activities. Provide two examples of each.
3) Compare and contrast two of these three methodologies for conducting a process hazard analysis:
HAZOP Study
What-If Analysis
Failure Mode and Effects Analysis
Be sure to discuss strengths and weaknesses of each of the two methods you selected.
4) Consider a scenario where methyl isocyanate (MIC) gas is leaking from a blown flange gasket. When you step outside the control room, your eyes begin to water and you begin to cough. You go back inside the room just as an alarm sounds in the control room and an outside sensor reports 300 PPM MIC in the ambient atmosphere outside the control room. Find a Safety Data Sheet for methyl isocyanate on the Internet and answer the following questions:
What level of PPE will you don to search for and contain the leak?
List each item of PPE you will wear.
