Which position has the authority to immediately terminate any unsafe work practice?

• A. Incident Commander
• B. Safety Officer
• C. Public Information Officer
• D. Liaison Officer

Answer: (B)

The key idea is that on the incident scene, the person responsible for safety has the power to stop any unsafe work right away to prevent injuries or further hazards. In the Incident Command System, the Safety Officer watches over operations to identify hazards, ensure proper safety measures, and, when something dangerous is happening, suspend or stop that activity immediately until it’s safe. This immediate authority to halt unsafe actions is what keeps responders protected and hazards under control.

The other roles aren’t focused on enforcing on-scene safety decisions. The Incident Commander has overall command of the incident, but the authority to halt risky work as a proactive safety measure sits with the Safety Officer. The Public Information Officer handles communications with the public and media, while the Liaison Officer coordinates with external agencies; neither is responsible for stopping unsafe field practices.
