Question 2

When calculating the Number Needed to Harm (NNH), which formula is correct?

Accepted Answer

1 / Attributable Risk Increase

Answer

NNH equals 1 divided by the absolute increase in risk (attributable risk increase) associated with the harmful exposure.

Question 3

A food safety inspector applies the HACCP (Hazard Analysis Critical Control Points) framework. A 'critical control point' is best defined as:

Accepted Answer

A step where control can be applied to prevent or eliminate a food safety hazard

Answer

A critical control point is a specific process step where a control measure can be applied to prevent, eliminate, or reduce a food safety hazard to an acceptable level.

Question 4

Which cognitive bias most commonly leads risk assessors to underestimate the probability of rare but catastrophic events?

Accepted Answer

Optimism bias

Answer

Optimism bias causes people to believe that negative events are less likely to happen to them or their projects than the evidence warrants.

Question 5

A risk manager identifies that a control measure has become less effective over time due to staff complacency. This phenomenon is known as:

Accepted Answer

Normalisation of deviance

Answer

Normalisation of deviance describes the gradual process by which deviation from safe practice becomes accepted as normal within an organisation.
