In a Means of Egress System, which set of elements makes up the three basic components?

• A. Entrances, Corridors, Elevators
• B. Public Way, Private Way, Lobby
• C. Exit Access, Exit, Exit Discharge
• D. Fire Alarm, Fire Suppression, Notification

Answer: (C)

The fundamental idea tested is how a Means of Egress is organized as a continuous path from where people are to where they can be safe outside. That path is divided into three basic components: exit access, the exit, and exit discharge. Exit access is the portion that starts in the occupied space and leads to an exit; it includes rooms, corridors, or doorways that channel people toward the exit. The exit is the protected segment that provides a safe, fire-resistant path to the exterior or to a safe area—think of stairwells or enclosed corridors that resist smoke and heat. Exit discharge is the segment from the exit to the outside world or to a safe area beyond the building, such as a public way. Together, these three parts form a continuous route for safe egress.

The other options describe spaces or systems that aren’t the formal three components of the Means of Egress. For example, entrances, corridors, and elevators relate to building features but do not define the tripartite structure of means of egress; public/private ways and lobbies are architectural spaces, not the three egress components; fire alarm, fire suppression, and notification pertain to safety systems, not the egress path segmentation.
