RCA RCA Prevention and Control

Question 1

What is the primary goal of implementing preventive actions after completing a Root Cause Analysis?

Accepted Answer

To eliminate or reduce the likelihood of recurrence

Answer

Preventive actions aim to eliminate or reduce the likelihood that the same root cause will produce another incident in the future.

Question 2

Which type of control is considered most effective in the hierarchy of controls for preventing recurrence?

Accepted Answer

Engineering/elimination controls

Answer

Engineering controls and elimination are at the top of the hierarchy of controls because they physically remove or reduce the hazard rather than relying on human behavior.

Question 3

A 'barrier analysis' in RCA prevention focuses on which of the following?

Accepted Answer

Evaluating controls that should have prevented the event but failed

Answer

Barrier analysis examines the safeguards or controls that were in place, why they failed to prevent the event, and how stronger barriers can be implemented.

Question 4

When ranking preventive actions, which criterion is MOST important to consider first?

Accepted Answer

Effectiveness in addressing the root cause

Answer

Effectiveness in actually addressing the root cause is the primary criterion because a cheap, easy action that doesn't fix the root cause provides little value.

Question 5

What is a 'poka-yoke' device used for in RCA prevention strategies?

Accepted Answer

Making errors physically impossible or immediately detectable

Answer

Poka-yoke (mistake-proofing) devices are design features that make it impossible or very difficult for errors to occur, removing reliance on human vigilance.
