When controlling a door during interior fire attack, which side should you maintain control of to minimize fresh air?

• A. Latch side
• B. Hinge side
• C. Top edge
• D. Bottom edge

Answer: (A)

Control of the door from the latch side is essential for restricting ventilation. The latch side is where the door has its handle and locking mechanism, so keeping your grip and control there lets you hold the door closed against the influx of air that pressure changes can cause. When you maintain control on the latch side, you can more effectively resist the door being driven open by door frame forces or by teammates on the other side, which minimizes the amount of fresh air entering the fire compartment. That reduced air supply helps slow the fire and improves conditions for both search and rescue and advancement of the line. Trying to control from the hinge side is less reliable because the door can swing more freely under pressure, increasing ventilation into the space. Top or bottom edge control isn't as practical or effective for maintaining a tight, controllable seal and can be easily compromised.
