To coordinate vertical ventilation with suppression teams, firefighters should do which of the following?

• A. Coordinate timing and placement of vents with suppression actions
• B. Only use ventilation after fire is out
• C. Vent independently without communication
• D. Ignore suppression teams

Answer: (A)

Coordinating vertical ventilation with suppression actions is essential to control how the fire behaves and to keep both occupants and firefighters safer. Ventilation changes the pressure and airflow inside the structure. If vents are opened without syncing with the suppression team, you can unintentionally feed the fire with more oxygen, create dangerous flow paths that push heat and flames into unvented areas, or trigger backdraft or flashover conditions. By aligning when and where you vent with where suppression crews are applying water and how they’re advancing lines, you direct the heat and smoke toward the exterior and away from colleagues and uninvolved zones, while the fire is being cooled and contained. This coordination also helps ensure ventilation on the correct floors or shafts and prevents venting into areas still heavily involved in the fire. Good communication with the incident commander and suppression teams is the backbone of this approach, enabling ventilation to occur in phases and in relation to the ongoing suppression strategy. Venting only after the fire is out, venting independently without communication, or ignoring suppression teams all fail to manage airflow in a way that keeps conditions tenable and safe.
