Which building design feature aims to limit fire to its origin by containing it within compartments?

• A. Compartmentation
• B. Containment
• C. Sealing
• D. Fireproofing

Answer: (A)

Fire compartmentation is the design approach that confines a fire to its origin by dividing a building into fire-resistive compartments. This relies on fire-rated walls, floors, and ceilings, with properly rated doors and controlled openings, to slow or stop heat, flame, and smoke from moving between spaces. By keeping the fire contained within a limited area, occupants have time to evacuate and firefighters gain better control of the incident. The other terms are less precise for this specific design goal: containment is broader and less about structuring the building into enclosed, rated sections; sealing focuses on closing openings to prevent movement of smoke and gases but doesn’t define a system of compartments; fireproofing protects structural elements from heat rather than limiting the fire’s spread to a single area.
