CHANGE TYPE: New
CHANGE SUMMARY: Existing exterior fire escapes require an inspection by a registered design professional or persons acceptable to the fi re code official no more than every 5 years.
2012 CODE: 1104.16.5 Materials and Strength. Components of fire escape stairs shall be constructed of noncombustible materials. Fire escape stairs and balconies shall support the dead load plus a live load of not less than 100 pounds per square foot(4.78 kN/m2). Fire escape stairs and balconies shall be provided with a top and intermediate handrail on each side. The fire code official is authorized to require testing or other satisfactory evidence that an existing fire escape stair meets the requirements of this section.
Fire escape stairs and balconies shall be examined for structural adequacy and safety, in accordance with Section 1104.16.5, by a registered design professional or others acceptable to the fire code official every five years, or as required by the fire code official. An inspection report shall be submitted to the fire code official after such examination.
CHANGE SIGNIFICANCE: Building fire escapes are a means-of-egress component in many existing multiple-story buildings. Neither the IBC nor IFC contains a specific definition as to what actually constitutes a fire escape, and in previous editions of the codes, they did not establish a frequency for their inspection. The IBC provisions for existing building in Section 3406.1.2 only permits a fire escape as a means-of-egress component in existing buildings and limits the installation of new fire escapes on existing buildings when the building code official determines they are necessary based on the substantiation by the registered design professional that exterior stairways cannot be used due to the lot line limiting the size of the stair, or conditions where the fire escapes could impact the egress path in sidewalks, alleys, or roads at grade. Additionally,new fire escapes, when allowed by the building code official, cannot utilize ladders or windows as a means of egress component. Fire escapes are typically prohibited in new construction.
A new requirement in Section 1126.96.36.199 establishes an inspection frequency for fire escapes and balconies erected on existing buildings. By design, fire escapes present a lot of concern to code officials because the stairs, ladders, balconies, and mechanical fasteners are commonly constructed of carbon or galvanized steel, which will rust if not properly maintained. Rust is a metal oxide that corrodes and damages carbon or galvanized steel and reduces its strength. The evaluation is necessary to
confirm that this exterior stair egress component satisfies a minimum design load requirement prescribed in Section 1104.16.5, is properly maintained, and is available for service in the event of an emergency that requires the occupants to egress the building. Unless otherwise specified by the fire code official, the 2012 IFC requires an inspection of fire escapes and their balconies every 5 years.
Fire escapes are now subject to specific examination requirements. 1188.8.131.52.
128 PART 3 ■ Building and Equipment Design Features
The individual evaluating fire escapes is required to be a registered design professional or an individual approved by the fire code official. The evaluation should include a review of the requirements in ASCE 7, Minimum Design Loads for Buildings and Other Structures, including the requirements in Section 13.4 for mechanical fasteners and Section 4.4 for handrails and grab bars. If adopted by the jurisdiction, the individual performing the inspection should also review the ASCE 7 Appendix 11B requirements for existing buildings.
