The International Building Code (IBC) defines a complete means of egress system as consisting of three basic elements: exit access (the path from any occupied space to an exit, e.g., corridors), exit (a protected enclosure, e.g., an enclosed stairway), and exit discharge (the path from the exit to a public way, e.g., an exterior door to the street). For an office suite on the second floor, this includes the path through the office to a stairway (exit access), the stairway itself (exit), and the path to the outside (exit discharge). Option A (corridors, hallways, and stairs) describes parts but not the complete system. Option B (hallway, lobby, lobby door) misses the exit discharge. Option D (panic hardware, alarms, exit sign) lists components, not the system elements.

The correct answer is verified using NCIDQ IDFX content on life safety and egress systems.

Exact Extract:TheNCIDQ IDFX Reference Manualreferences IBC standards, stating, “A complete means of egress system includes exit access, exit, and exit discharge, ensuring a continuous path from any occupied space to a public way.”

The NCIDQ IDFX curriculum requires understanding the IBC’s definition of egress systems, with exit access, exit, and discharge being the fundamental elements.
