How can door and window management help control smoke movement?

• A. Door and window management and containment.
• B. Always increasing ventilation.
• C. Blocking all doors during operations.
• D. Using only fans.

Answer: (A)

Controlling smoke movement hinges on shaping airflow by how openings are managed. Smoke tends to follow the path of least resistance, so intentionally closing doors and using windows in a planned sequence helps create barriers between the fire and other spaces and builds pressure differences that guide smoke toward a safe exhaust path. This containment approach keeps escape routes open and preserves safer areas for occupants and responders. Ventilation is about strategic venting that supports protection, not simply increasing air flow everywhere. Doors and windows are tools to compartmentalize and stage venting safely, rather than options used in isolation.
