Fundamentals Of Fire Safe Building Design Practice Test

Which approach primarily affects air flow within compartments to manage fire growth?

Exterior wall color Sealing vents and compartments Installing fire-rated doors Window blind type

Correct Answer:

Sealing vents and compartments

Explanation:

Ventilation control is what governs how a fire grows inside a building. Limiting air flow into and between compartments directly reduces the oxygen available for the flame and slows the movement of hot gases, which slows heat release and flame spread. Sealing vents and compartments cuts off those air paths, making it the most effective way to manage fire growth within spaces. Exterior wall color doesn’t affect airflow or fire behavior. Fire-rated doors help contain fire by adding barrier properties, but airflow inside rooms is still driven by openings that allow air to move; if vents or gaps exist, air can still feed the fire. Window blind type has little to no impact on the ventilation dynamics during a fire.
