About this chapter: Chapter 19 provides guidance by which egress systems for buildings and facilities are designed, evaluated and maintained. This chapter and Section 701 contain the same provisions. It was determined that both Part II and Part III ultimately have the same objectives with regard to egress. It was decided to duplicate the objectives and functional statements in both Parts II and III and to reference the reader from Section 701.3 to Chapter 19 for the performance requirements, primarily because Part III is always intended to be adopted. Because the provisions in Chapter 19 also relate to existing situations, it is more appropriate for those provisions to be found in this chapter.
The construction, arrangement and number of means of egress, exits and safe places for buildings shall be appropriate to the travel distance, number of occupants, occupant characteristics, building height, and safety systems and features.
Suitable means of egress shall be provided in satisfactory arrangement throughout all buildings, facilities and premises, regardless of when they were constructed, based on the number and character of occupants, length of travel, provision of existing alternative paths, timeline of emergency detection and response, risk level, time to exit and safety systems provided.
Means of egress shall be maintained and operated in such a manner to ensure that all egress facilities are readily openable and available without special knowledge or effort consistent with the use or occupancy characteristics.
