Once overhead doors have been forced open, they should be:

• A. removed.
• B. unlocked to prevent relocking.
• C. locked.
• D. blocked open.

Answer: (D)

Securing an overhead door after it has been forced is about keeping the opening accessible for crews and for ventilation, while preventing the door from closing and relocking. Blocking the door open with a wedge or similar device ensures it stays in the open position, so it won’t spring back shut or relock on its own. This keeps the entry usable for quick access and helps exhaust heat and smoke as the operation continues. Removing the door isn’t needed and wastes time and effort; leaving it unlocked doesn’t guarantee it won’t close and relock, and locking it would prevent access and ventilation. Blocking open gives you a safe, practical balance for scene safety and efficiency.
