Which are part of a means of egress?

• A. Corridor, stairs, aisles
• B. Overhead door, non-rated corridor, alley
• C. Through kitchen, corridor, street
• D. Through mechanical room, fenced in yard, street

Answer: (A)

Means of egress is the path occupants follow to reach safety from any occupied part of a building, ending at a public way. The interior portions of that path include corridors, stairs, and aisles—the channels you walk through to reach an exit. These elements are the primary travel routes inside the building that guide you toward an exit while maintaining safe widths and fire barriers. The other options mix elements that aren’t standard interior egress components: an overhead door is a door type rather than a required egress path; a non-rated corridor wouldn’t meet fire-resistance requirements; an alley or street is the exit discharge destination, not the interior means of travel; a kitchen or mechanical room is a space you might pass through but isn’t itself a typical component of the means of egress.
