Dynamic risk assessment describes which concept?

• A. The continuous assessment of risk in rapidly changing circumstances of an operations incident in order to implement the control measures necessary to ensure an acceptable level of safety.
• B. A one-time hazard check at the start of an incident.
• C. A method for collecting witness statements.
• D. A post-incident review process.

Answer: (A)

Dynamic risk assessment is the ongoing, real-time evaluation of risk as conditions on the ground change during an incident, so that you can adjust control measures to keep safety at an acceptable level. It means constantly surveying the scene, re‑evaluating hazards as new information emerges, and updating actions like PPE, 거리 management, or stop-work decisions in response to those changes. This explains why the description of continuous assessment in rapidly changing circumstances and implementing necessary controls is the best match.

By contrast, a one-time hazard check at the start doesn’t account for evolving risks; collecting witness statements focuses on gathering information after events have occurred; and a post-incident review looks back to learn lessons after the incident rather than managing risk in real time.
