Which term describes a path through a fire barrier or between buildings on the same level?

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

Answer: (A)

A horizontal exit is a protected route that lets people move through a fire barrier or between buildings on the same level. Its purpose is to carry occupants to a safe, fire-resisted area on the same floor so they aren’t crossing to a different level while the fire is active. Once in the protected space, they can continue toward an actual exit or wait for it depending on the building layout. This differs from an exit enclosure, which refers to the vertical protected area around stairs or other vertical egress, and from an exit passageway, which is a protected corridor that leads to an exit route—typically toward the outside. An area of refuge, on the other hand, is a designated safe space for people who cannot use stairs, not a crossing path between areas on the same level.
