The means of egress from a building should include.

• A. Public ways of adjoining properties with restricted access
• B. Exit signs above each vertical exit
• C. Unobstructed passageways
• D. Elevators for occupants

Answer: (C)

Means of egress must provide a continuous, unobstructed path from occupied areas to safety. When passageways are clear and wide enough, occupants can move quickly and safely without being blocked or redirected, which is essential for an effective evacuation. Public ways of adjoining properties with restricted access aren’t reliable parts of the building’s escape routes—they may not be accessible or safe during an emergency, so they don’t fit the means of egress. Exit signs help people find exits, but they don’t replace the need for clear, passable routes. Elevators are not considered a standard means of egress during emergencies because they can fail or trap occupants, so they aren’t relied upon for evacuation.
