Neither NBC or IBC contains many provisions that specifically
require or address the inspection of firestop systems. However, there
are a few provisions that should be looked at, and depending on the
jurisdiction’s requirements, it may affect how the firestop provisions
are applied. Although not directly addressing firestopping, two
sections to consider are IBC Sections 107.2.1, related to information
on construction documents, and IBC Section 104.1, related to the
powers of the building official. Four sections that specifically relate
to firestopping will also be discussed so that code users are aware
of the requirements and the intent behind the provisions. These
include:

IBC Section 110.3.6, which requires the protection of joints and
penetrations to remain accessible and not be concealed until

IBC Section 1705.17, which requires special inspections for through
penetrations, membrane penetrations, fire-resistant joint systems
and perimeter fire barrier systems when they are installed in high-
rise buildings or in buildings assigned to Risk Category III or IV per

IBC Section 703.7, which requires marking and identification of
