What is the purpose of a fire compartment?

• A. To protect against earthquakes
• B. To minimize heat generation
• C. To accommodate more occupants
• D. To limit the spread of fire and smoke within a defined area

Answer: (D)

Fire compartments are built to confine fire and smoke to a defined area. By separating spaces with fire-resistance rated walls, floors, and doors, heat, flames, and dangerous gases are slowed or stopped from crossing into adjacent areas. This containment buys critical time for people to escape and for firefighters to operate, while helping keep the remainder of the building cooler and more structurally stable during a fire. The purpose isn’t to address earthquakes, minimize heat generation, or increase occupancy; it’s to limit the spread of fire and smoke within a defined area.
