What is the safe ventilation practice to improve survivability?

• A. Ventilate immediately without coordination.
• B. Close all vents to trap smoke.
• C. Ventilate only when there is no active fire.
• D. Ventilate in coordination with suppression to avoid feeding smoke back into the area where firefighters are working or victims.

Answer: (D)

Coordinated ventilation manages airflow to control heat, smoke, and toxic gases while keeping crews and potential victims safe. Venting should be done in partnership with suppression so the smoke removal path doesn’t push hot gases toward areas where people are sheltering or where firefighters are operating. This controlled approach helps reduce the thermal layer, improves visibility, and lowers exposure, thereby improving survivability for occupants and safety for responders. Opening vents without coordination can spread smoke or heat into the wrong areas, closing vents traps heat and smoke and worsens conditions, and waiting for no active fire can allow dangerous conditions to develop.
