About this chapter: Chapter 7 provides requirements to maintain the fire-resistance ratings of building elements and to limit fire spread. Section 701 addresses the maintenance of and owner's responsibility for construction elements such as fire barriers and smoke barriers. The rest of the chapter deals with various aspects that also must be maintained to achieve overall fire resistance of the main fire- and smoke-resistive features. These include penetrations, joint protection, door and window openings, and duct and air transfer opening protection.
- Special Assembly Occupancies, including any exit enclosures providing a means of egress from spaces containing such occupancies.
- Group I-2 occupancies, including any exit enclosures providing a means of egress from spaces containing such occupancies.
- Vertical ventilation shafts located within high-rise buildings where the shaft has a minimum fire resistance rating of one-hour.
- Unobstructed access to the damper shall be verified and corrected as required.
- An operation test of the damper shall verify that the damper closes and that there is no damper interference due to rusted, bent, misaligned or damaged frame or blades, or defective hinges or parts.
- The damper frame shall not be penetrated by any foreign objects that would affect fire damper operations.
- The damper shall not be blocked from closure in any way.
- The fusible link (if applicable) shall be reinstalled after the completion of the operation testing.
- If the fusible link (if applicable) is damaged or painted, it shall be replaced with a link of the same size, temperature and load rating.

Where any components in this chapter are not maintained and do not function as intended or do not have the fire resistance or the resistance to the passage of smoke required by the code under which the building was constructed, remodeled or altered, such component(s) or portion thereof shall be deemed an unsafe condition, in accordance with Section 111.1.1. Components or portions thereof determined to be unsafe shall be repaired or replaced to conform to that code under which the building was constructed, remodeled, altered or this chapter, as deemed appropriate by the fire code official.
Where the condition of components is such that any building, structure or portion thereof presents an imminent danger to the occupants of the building, structure or portion thereof, the fire code official shall act in accordance with Section 111.2.
Where required when the building was originally constructed, materials and systems used to protect joints and voids in the following locations shall be maintained. The materials and systems shall be securely attached to or bonded to the adjacent construction, without openings visible through the construction.
- Joints in or between fire-resistance-rated walls, floors or floor/ceiling assemblies and roof or roof/ceiling assemblies.
- Joints in smoke barriers.
- Voids at the intersection of a horizontal floor assembly and an exterior curtain wall.
- Voids at the intersection of a horizontal smoke barrier and an exterior curtain wall.
- Voids at the intersection of a nonfire-resistance-rated floor assembly and an exterior curtain wall.
- Voids at the intersection of a vertical fire barrier and an exterior curtain wall.
- Voids at the intersection of a vertical fire barrier and a nonfire-resistance-rated roof assembly.
Unprotected joints and voids do not need to be protected where such joints and voids were not required to be protected when the building was originally constructed.
