Which practice helps confirm the effectiveness of corrective actions after a safety incident?

• A. Leave it to the equipment managers to decide.
• B. Record the action and forget about it.
• C. Verify effectiveness through follow-up checks and metrics.
• D. Report only to higher command.

Answer: (C)

Verifying the effectiveness of corrective actions relies on follow-up checks and metrics to prove that the changes actually reduced risk and are sustaining over time. By conducting targeted follow-up observations and collecting relevant data, you can see whether the new controls function as intended and meet predefined success criteria. This objective evidence allows you to confirm what worked, what didn’t, and what adjustments are needed to prevent recurrence. Relying solely on someone’s judgment without verifying outcomes leaves the safety improvements untested, while recording actions or escalating without closing the loop fails to provide the necessary feedback for true improvement.
