Which principle focuses on reviewing the effectiveness of controls through accident/incident reporting?

• A. Provide information and training.
• B. New measures, new risks.
• C. PPE (final control option).
• D. Accident/incident reporting.

Answer: (D)

Using accident and incident reporting to evaluate how well controls work is about closing the loop on risk management. When accidents or near-misses occur, recording details and analyzing causes shows whether the existing controls prevented harm or where gaps remain. This information lets you judge the effectiveness of safeguards and drive improvements—adjusting procedures, training, or engineering controls as needed to reduce risk further. Other options contribute to risk reduction, but they don’t provide the ongoing assessment of control performance that incident reporting offers.
