Section 704 Joints and Voids

California Fire Code 2019 > 7 Fire and Smoke Protection Features > 704 Joints and Voids
JUMP TO FULL CODE CHAPTER

704.1 Maintaining Protection

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.

  1. Joints in or between fire-resistance-rated walls, floors or floor/ceiling assemblies and roof or roof/ceiling assemblies.
  2. Joints in smoke barriers.
  3. Voids at the intersection of a horizontal floor assembly and an exterior curtain wall.
  4. Voids at the intersection of a horizontal smoke barrier and an exterior curtain wall.
  5. Voids at the intersection of a nonfire-resistance-rated floor assembly and an exterior curtain wall.
  6. Voids at the intersection of a vertical fire barrier and an exterior curtain wall.
  7. 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.

704.2 Opening Protectives

Where openings are required to be protected, opening protectives shall be maintained self-closing or automatic-closing by smoke detection. Existing fusible-link-type automatic door-closing devices are permitted if the fusible link rating does not exceed 135°F (57°C).
