Basic Occupational Safety and Health (BOSH) Safety Officer 2 Practice Exam

In an Emergency Response Plan, on-scene coordination is handled by the incident command. This element defines who leads the response on-site, sets priorities, and directs all actions and resources in real time. The Incident Commander has the authority to make critical decisions, coordinate with other responders, and maintain overall control of the situation to protect life and property.

Alarm and notification is about alerting people that an incident is occurring, not directing on-scene actions. Evacuation routes focus on safe paths for people to exit the area, not who supervises or directs the response. Roles and responsibilities outline who should do what tasks, but the on-scene coordination—the actual command, decision-making, and management of the incident—is established by the incident command structure.
