Means of egress includes three major components. Which of the following is NOT one of them?

• A. Exit access
• B. Exit
• C. Fire barrier
• D. Exit discharge

Answer: (C)

Means of egress is the safe path people follow to reach safety in an emergency, and it has three major components: exit access, the actual exit, and exit discharge. Exit access is the part from any occupied space that leads toward an exit—like corridors, doors, or stairs that bring you closer to an exit. The exit itself is the protected way the occupant travels to reach a safe place, such as a stairwell or a labeled egress door. Exit discharge is the portion from the exit to the exterior or to a safe area outside the building, including outdoor pathways or entrances that lead away from the building. A fire barrier, by contrast, is a fire-resistance-rated wall designed to restrict fire and smoke, helping to compartmentalize the building; it isn’t one of the three components that make up the means of egress. So the option that is not part of the means of egress is the fire barrier.
