Elements of a Means of Egress System

Egress System Components: Exit Stair, Exit Passageway & Exit Discharge

What are the Elements of a Means of Egress System?

  • EXIT ACCESS
  • EXIT
  • EXIT DISCHARGE
Egress System Components: Exit Access, Exit Stair

Exit Access & Exit Stair

EXIT ACCESS

That portion of a means of egress system that leads from any occupied portion of a building or structure to an exit. (ie: everything from the furthest point in an occupied room to the corridor that provides access to the egress stairs)

EXIT

That portion of a means of egress system, which is separated from other interior spaces of a building or structure by fire-resistance-rated construction and opening protective as required to provide a protected path of egress travel between the exit access and the exit discharge. Exits include vertical exits, exterior exit doors at ground level, exit enclosures, exit passageways, exterior exit stairs, exterior exit ramps and horizontal exits, but do not include access stairs, aisles, exit access doors opening to corridors, or corridors. (ie: everything from the exit stairs to the doors that lead to the exterior)

EXIT DISCHARGE

That portion of a means of egress system between the termination of an exit and a public way. (ie: basically the doors that open to the exterior.)

Everything you need to know to design a Means of Egress System

In short, there is A LOT to consider when designing a means of egress system. I started a checklist below of everything you need to consider, divided into the three main components. The checklist is a work in progress and does not include everything you may need to consider. Please let me know in the comments below if something is missing and I will add it to the list ASAP.
