About this chapter: Chapter 10 provides the general criteria for designing the means of egress established as the primary method for protection of people in buildings by allowing timely relocation or evacuation of building occupants. Both prescriptive and performance language is utilized in this chapter to provide for a basic approach in the determination of a safe exiting system for all occupancies. This chapter addresses all portions of the egress system (exit access,exits and exit discharge) and includes design requirements as well as provisions regulating individual components. The requirements detail the size, arrangement, number and protection of means of egress components. Functional and operational characteristics that will permit the safe use of components without special knowledge or effort are specified.
The means of egress protection requirements work in coordination with other sections of the code, such as protection of vertical openings (see Chapter 7), interior finish (see Chapter 8), fire suppression and detection systems (see Chapter 9) and numerous others, all having an impact on life safety. Sections 1003 through 1030 are duplicated text from Chapter 10 of the International Building Code®; however, the International Fire Code® contains an additional Section 1031 on maintenance of the means of egress system in existing buildings. Retroactive minimum means of egress requirements for existing buildings are found in Chapter 11.
- Proposed (new) buildings or portions thereof approved for construction as set forth in 103.3 of this Code, shall be provided with means of egress and related safeguards as set forth by NFPA 101, Life Safety Code, as adopted this Chapter. (Refer to Table 102.13, CODES REFERENCE GUIDE)
- Buildings and structures existing and approved prior the effective date of this Chapter 120-3-3, as set forth in 103.3 of this Code, having means of egress and related safeguards conforming to NFPA 101, Life Safety Code, under which they were approved and constructed shall be considered as complying with this Code. Means of egress and related safeguards in existing buildings constructed without approval, may be considered as complying with this code section if, in the judgment of the authority having jurisdiction, they do not constitute a distinct hazard to life. Where, in the judgment of the authority having jurisdiction, the means of egress or related safeguards provided constitute a distinct hazard to life, the hazardous condition or conditions shall be remedied based on the provisions for existing buildings of the Life Safety Code as adopted by this Chapter 120-3-3.
- Exit discharge termination dispersal areas may be utilized where authorized and designed in accordance with 18.104.22.168 of the Life Safety Code, as adopted by Chapter 120-3-3 of the Rules and Regulations of the Safety Fire Commissioner.

In Group E occupancies, Group B educational occupancies and Group I-4 occupancies, egress doors from classrooms, offices and other occupied rooms shall be permitted to be provided with locking arrangements designed to keep intruders from entering the room where all of the following conditions are met:
- The door shall be capable of being unlocked from outside the room with a key or other approved means.

- Modifications shall not be made to existing listed panic hardware, fire door hardware or door closers.
- Modifications to fire door assemblies shall be in accordance with NFPA 80.
In Group I-2, the required clear width for aisles, corridors and ramps that are part of the required means of egress shall comply with Section 1020.2. The facility shall have a plan to maintain the required clear width during emergency situations.
Exception: In areas required for bed movement, equipment shall be permitted in the required width where all of the following provisions are met:
- The equipment is low hazard and wheeled.
- The equipment does not reduce the effective clear width for the means of egress to less than 5 feet (1525 mm).
- 3.1. Equipment and carts in use.
- 3.2. Medical emergency equipment.
- 3.3. Infection control carts.
- 3.4. Patient lift and transportation equipment.
- Medical emergency equipment and patient lift and transportation equipment, when not in use, are required to be located on one side of the corridor.
- The equipment is limited in number to not more than one per patient sleeping room or patient care room within each smoke compartment.
Required emergency escape and rescue openings shall be maintained in accordance with the that was code in effect at the time of construction, and both of the following:
- Required emergency escape and rescue openings shall be operational from the inside of the room without the use of keys or tools.
- Bars, grilles, grates or similar devices are allowed to be placed over emergency escape and rescue openings provided that the minimum net clear opening size complies with the code that was in effect at the time of construction and such devices shall be releasable or removable from the inside without the use of a key, tool or force greater than that which is required for normal operation of the emergency escape and rescue opening.
