Which term describes a fire-resistant path from the base of stairs to an exit door?

• A. Exit Enclosure
• B. Exit Passageway
• C. Horizontal Exit
• D. Area of Refuge

Answer: (A)

The main idea is a fire-resistive, protected path that ensures safe egress from the base of a stair tower up to the exit door. That protected route is called an exit enclosure. It describes a portion of the building’s exit system that is fully enclosed by fire-resistance-rated construction, keeping heat, smoke, and flames out of the travel path as people move toward an exit door. This enclosure surrounds the stairs and the immediate egress area, delivering a safer route during a fire.

Why this fits best: the term specifically denotes a protected, fire-rated path from the bottom of the stairs to the exit door, which is exactly the scenario described. The other terms refer to related but different concepts: an exit passageway is a protected corridor used within the egress system but not necessarily the enclosed route around the stairs; a horizontal exit involves moving through a fire barrier to a different area on the same level or into another building; an area of refuge is a safe space for occupants who may need assistance or more time before evacuating, not a route to the exit.
