Which crew roles typically coordinate on a vertical ventilation operation?

• A. Roofer, Painter, Landscaper, Auditor
• B. Chief Engineer, Public Relations Officer, Planner, Scientist
• C. Incident Commander, Ventilation Team Lead, Interior Fire Attack Team, and Communications Lead
• D. All roles are unnecessary; one person does all tasks

Answer: (C)

Vertical ventilation relies on a coordinated on-scene command structure where four roles work together: Incident Commander, Ventilation Team Lead, Interior Fire Attack Team, and Communications Lead. The Incident Commander maintains overall safety and strategy for the incident, including when and how to ventilate. The Ventilation Team Lead plans the roof operations, coordinates with interior crews about timing and placement, and directs the physical execution of the vent opening and air movement. The Interior Fire Attack Team handles interior suppression and rescue tasks, providing essential information about conditions inside the space and responding to changes caused by ventilation, such as wind shifts or pressure changes. The Communications Lead ensures clear, continuous communication among teams, relays updates to the incident command, and maintains reliable channels with all crews.

This setup is essential because vertical ventilation changes the interior environment rapidly and affects fire behavior. Having these distinct but integrated roles ensures decisions are informed, actions are synchronized, and safety is prioritized. The other options describe roles that aren’t part of the typical on-scene team for vertical ventilation, or suggest one person could handle everything, which is unsafe and impractical for coordinating a ventilation operation.
