How is “means of egress” defined in building design?

The definition of “means of egress” in building design is fundamentally the system that provides a safe way for occupants to exit a building in the event of an emergency. This encompasses all components that create a continuous exit route from occupied spaces, including corridors, stairwells, exits, and other pathways that lead to a place of safety.

Having a continuous exit route is crucial for ensuring that occupants can evacuate swiftly and safely, which is a primary objective in building safety codes and regulations. Understanding this definition helps architects and designers ensure compliance with safety standards and effective emergency planning.

The other options do not align with the definition of means of egress. For instance, a designated area for storage does not relate to exit routes. The main entrance of a building pertains specifically to access rather than the comprehensive exit pathways that constitute means of egress. Lastly, a framework for structural support exists to uphold the physical integrity of the building rather than provide a safe exit route for occupants.
