Which statement describes exit enclosures?

• A. To house elevator shafts.
• B. To create extra storage.
• C. To provide protected paths for egress and prevent smoke and fire spread.
• D. To serve as decorative elements.

Answer: (C)

Exit enclosures are protected paths used for getting people out safely, built to resist fire and keep smoke from entering the evacuation route. They surround essential egress routes—like stairways or other exits—with fire‑resistance rated construction and self-closing doors so the path remains tenable even as the surrounding area burns. This containment slows the spread of heat and smoke into the way out, giving occupants time to evacuate and helping firefighters access the building. Elevator shafts are not intended as the primary egress path during a fire, and using them can expose people to heat and smoke, so housing elevator shafts isn’t the purpose of an exit enclosure. Extra storage or decorative elements do not contribute to the protective function of the egress pathway.
