When entering or exiting a hostile environment, how should you handle doors?

• A. Slam doors to save time.
• B. Keep doors controlled and closed; open only as needed, and maintain awareness of fire behavior behind the door.
• C. Leave doors open to vent as needed.
• D. Remove doors completely.

Answer: (B)

Doors act as protective barriers that help manage heat, smoke, and fire behavior as you move in and out. Keeping doors controlled and closed preserves a tenable area, slows fire spread, and concentrates the available oxygen and visibility for safe movement. Open the door only as needed to pass or to assess conditions, then close it to re-establish the barrier. While the door is closed you should stay aware of what’s happening behind it—listen for changes in crackling, feel for heat, and watch smoke movement and color—so you can decide when and how to vent or advance. Opening doors widely or leaving them open feeds the fire, increases heat and smoke, and can cause rapid deterioration, including backdraft or flashover. Doors should not be removed; they are essential for controlling the environment and protecting both crew and potential victims.
