The three distinct parts of a "means of egress" include exit access, exit, and exit discharge.

Exit access refers to the portion of a means of egress that leads to the exit. This includes hallways, corridors, and any other path that leads people from their work area to an exit. It is vital as it ensures that occupants can navigate safely and efficiently towards an exit in case of an emergency.

The exit itself is the portion that provides a protected path of travel from the exit access to the exit discharge. This may include doors and stairways that lead out of the building, thereby separating the occupants from potential hazards inside.

Exit discharge completes the means of egress by providing a path between the exit and a public way (e.g., a street, alley, or other open space that can be accessed safely). It is crucial because it signifies the final step of evacuation, allowing people to reach safety.

Together, these components ensure that in the event of an emergency, individuals can evacuate in a safe and organized manner, which is critical for minimizing injuries and fatalities. Other options listed do not encompass all three components or incorrectly categorize elements of the means of egress.
