This document summarizes key components of a building's means of egress system including exit access, exits, and exit discharge. It discusses requirements for distance between exits, dead-end corridors, maximum travel distance, doors, exit stairways, and exit passageways as outlined in building codes. Requirements include a minimum distance between exits of half the building diagonal, no more than 20 foot dead-end corridors, and maximum travel distances depending on building occupancy and path of egress. Exit components like stairways must have fire-rated enclosures and doors.
