Which of the following includes the MOST basic elements of a complete means of egress system for an office suite on the second floor?

According to building codes, a "means of egress" is a continuous and unobstructed path of travel from any point in a building to a public way. This system is fundamentally composed of three distinct parts: the exit access, the exit, and the exit discharge. The exit access is the portion that leads from any occupied space to an exit. The exit is the portion that is separated from other interior spaces to provide a protected path to the exit discharge (e.g., an enclosed stairwell). The exit discharge is the portion between the termination of an exit and a public way (e.g., a lobby or exterior court). These three components constitute the complete system.

A. Corridors, hallways, and stairs are specific examples of building elements that can be part of the means of egress, not the three fundamental categories that define the entire system.

B. A hallway, lobby, and lobby door represent an incomplete and specific list of components, not the comprehensive, defined parts of a complete means of egress system.

D. Panic hardware, alarms, and signs are required safety features and components within a means of egress system, but they are not the primary structural parts of the system itself.

Section 1002.1

Definitions. The code explicitly defines "MEANS OF EGRESS" as: "A continuous and unobstructed path of vertical and horizontal egress travel from any occupied portion of a building or structure to a public way. A means of egress consists of three separate and distinct parts: the exit access

the exit and the exit discharge."

2. National Fire Protection Association. (2021). NFPA 101: Life Safety Code. Chapter 7: Means of Egress

Section 7.1.2.2

Components. This standard states: "A means of egress consists of three separate and distinct parts: (1) The exit access (2) The exit (3) The exit discharge."

"Means of Egress

" the text and diagrams on page 268 clearly state and illustrate that a means of egress "consists of three parts: the exit access

the exit

and the exit discharge." This text is standard courseware in university architecture and interior design programs.
