CEM Hazard Identification & Risk Analysis 2

Question 1

Which quantitative risk analysis technique uses probability distributions to model uncertainty across thousands of simulated scenarios?

Accepted Answer

Monte Carlo simulation

Answer

Monte Carlo simulation runs thousands of random trials using probability distributions to estimate the range and likelihood of risk outcomes.

Question 2

In the context of a Hazard and Operability (HAZOP) study, what does the guide word 'MORE' indicate?

Accepted Answer

A quantitative increase in a parameter beyond design intent

Answer

The guide word 'MORE' in HAZOP signifies a quantitative increase, such as higher pressure or greater flow than the design specification allows.

Question 3

A jurisdiction experiences flooding once every 50 years on average. What is the annual probability of flooding occurring in any given year?

Accepted Answer

2%

Answer

A 50-year return period corresponds to a 1/50 = 2% annual probability of occurrence.

Question 4

Which type of hazard analysis specifically examines the sequence of events leading to an undesired top event using a logic diagram?

Accepted Answer

Fault tree analysis

Answer

Fault tree analysis uses a top-down deductive logic diagram with AND/OR gates to trace all combinations of failures that could cause a specific top event.

Question 5

In risk communication, the 'outrage' factor developed by Peter Sandman refers to:

Accepted Answer

Non-technical factors that influence public perception of risk

Answer

Sandman's outrage factors are non-technical elements—such as voluntariness, fairness, and trust—that heavily shape how the public perceives and responds to risk.
