If a facade over the main entryway could collapse, lines should be extended through which feature?

• A. Another entrance
• B. Rooftop vent
• C. Adjacent window
• D. Back door

Answer: (A)

When evaluating a potential collapse of the facade over the main entry, you focus on a safe way out. You extend lines along the intended path of travel to see if there is a viable alternate exit that isn’t compromised by the collapse. The best feature to extend the line through is a different entrance, because it represents a designed, accessible egress route that can be used even if the primary doorway is blocked. Rooftop vents aren’t built for occupants to escape through, and a window—even if adjacent—may be too small, high, or obstructed to use safely. A back door could be an option in some layouts, but it isn’t as reliable or standard a fallback as an additional entrance that’s clearly designated for egress. So extending the line to another entrance identifies a practical secondary route for exiting the building.
