Typically, the first officer to respond must take charge of the scene until relieved by -

• A. Command staff
• B. The on-site medical team
• C. The warden
• D. The shift supervisor from another unit

Answer: (A)

When an incident begins, the first officer on scene takes immediate charge to establish control, protect people, and begin coordinating initial actions. This on-scene command is kept until a Command Staff member arrives to assume control. The reason is to maintain a single, clear line of authority so directions, priorities, and resource allocations don’t become fragmented as the situation grows. Command Staff members are designated to oversee the overall response, make strategic decisions, manage resources, and maintain liaison with facility leadership and any outside agencies. The on-site medical team will handle medical care and triage, not command and control, so they don’t relieve command. The warden may oversee at a higher level, but the practical transfer of on-scene leadership is to the Command Staff, who have the authority to direct the incident across all functions. A shift supervisor from another unit could support as authorized, but the established protocol is for relief to come from the Command Staff to ensure continuity and accountability.
