Questions and Answers

What does a fault tree analysis diagram show?

  • The detailed analysis of process industry accidents
  • The path of specific accidents and the combination of events needed for an undesirable incident to occur (correct)
  • The annual probabilities of different failure modes
  • The consequences of an accident in the nuclear industry

    • Why was fault tree analysis developed for the nuclear industry?

  • The consequences of an accident are very severe, so highly detailed analysis was required (correct)
  • The process industries did not require detailed analysis
  • The nuclear industry had more frequent accidents
  • It was less costly to implement in the nuclear industry

    • In the given example, what can cause a distillation column explosion?

  • Operator error (OE) and instrument failure (IF)
  • Overhead unit failure (OUC) or problem with the reboiler (RB) (correct)
  • Power failure (PF) or failed tube (FT)
