Which term is best described as an exit that connects interior and exterior areas through a fire-resistance assembly?

• A. Travel Distance
• B. Ingress
• C. Horizontal Exit
• D. Hip Roof

Answer: (C)

The concept being tested is a protected interior-to-interior egress path that crosses a fire-resistance-rated barrier. A horizontal exit is a passage through a fire-resistance assembly that connects interior spaces on the same level, allowing occupants to move from the fire area into another portion of the building that can be used as a refuge or to continue toward the exterior without passing through an unprotected path. This makes it the best fit for describing an exit that goes through a fire-resistance rated barrier to connect interior spaces.

The other terms don’t fit this scenario: travel distance is a measurement of how far one must walk to reach an exit, not a type of exit; ingress means entering, not exiting; and a hip roof is an architectural roof style, unrelated to egress or fire resistance.
