In a dash displacement scenario, what should be done with the front doors?

• A. They should be forced closed
• B. They should be tied closed
• C. They should be tied open
• D. They should be removed

Answer: (C)

In a displacement ventilation scenario, the goal is to establish and maintain a continuous air flow path that moves smoke and hot gases out of the structure while allowing fresh air in. Keeping the front doors tied open ensures the doorway remains part of that open flow path and won’t slam shut or close on you as pressures shift or as crews move through. This setup helps prevent smoke from pooling behind a closed door and supports effective ventilation and rapid access. Forcing the door closed or tying it shut would disrupt the airflow, trap heat and gases, and hinder both ventilation effectiveness and firefighter safety. Removing the door isn’t necessary and can introduce additional hazards. Tying the door open is the safest, most effective choice to maintain the intended airflow.
