What term denotes a space within a building that is enclosed by fire barriers on all sides, including the top and bottom?

• A. Smoke Compartment
• B. Fire Compartment
• C. High-Rise Building
• D. Historic Building

Answer: (B)

Spaces bounded by fire barriers on all sides, including the bottom and the top, are called fire compartments. This concept is about containing a fire within a limited area to slow its spread and protect occupants and escape routes. The barriers must enclose the space on every boundary, so fire cannot easily move through walls, floors, or ceilings. If the enclosure were defined by smoke barriers instead, it would be a smoke compartment, which is geared toward limiting smoke movement rather than containing flames. The other options describe building types or design features, not the enclosed space defined by fire barriers.
