RCA RCA Prevention and Control 3

Question 1

Which approach is MOST effective for sustaining preventive action improvements over the long term?

Accepted Answer

Embedding changes into processes, training, and management systems

Answer

Embedding changes into standard operating procedures, training programs, and management systems institutionalizes the improvement, making it independent of any individual's memory or compliance.

Question 2

A 'risk matrix' is used in RCA prevention planning primarily to:

Accepted Answer

Prioritize risks by evaluating their likelihood and severity

Answer

A risk matrix plots the probability of a hazard occurring against its potential severity, allowing teams to prioritize which preventive actions should be implemented first.

Question 3

What does 'effectiveness verification' of a preventive action specifically require?

Accepted Answer

Collecting evidence that the root cause condition no longer exists

Answer

Effectiveness verification requires objective evidence—such as audit results, data trends, or inspections—showing that the root cause condition has been eliminated or sufficiently controlled.

Question 4

In RCA prevention, 'sharing lessons learned' across the organization serves what primary purpose?

Accepted Answer

Preventing similar incidents in other areas by spreading knowledge of root causes and fixes

Answer

Sharing lessons learned extends the benefit of a single RCA across the entire organization, preventing similar incidents in departments that have not yet experienced the same failure.

Question 5

Which of the following is an example of an administrative control used to prevent recurrence after an RCA?

Accepted Answer

Revising a standard operating procedure and retraining staff

Answer

Administrative controls include policies, procedures, training, and work practices—they rely on human compliance rather than physical or engineering changes.
