The systems will also vary be-
tween different manufacturers
and within individual product
lines. Therefore, designers, con-
tractors/installers and inspec-
tors need to avoid becoming
complacent and assuming that
all systems are created equal
or are installed in a similar man-
ner. They also need to avoid the
tendency of just looking to make
sure that the holes are filled or
that the firestop material is a
specific color.
Designers can improve the likeli-
hood of compliance by providing
a schedule of firestop systems
similar to the way in which they
provide window, wall, or door
schedules. In many situations,
the schedule of firestop systems
is done on a deferred submittal
basis. Installers and inspectors
can then follow the approved
plans and know exactly which
penetrations use which firestop
system or method of protection.
IBC Section 714 addresses specific requirements for maintaining
the integrity of the assemblies where penetrations occur. The re-
quirements within this section depend on the type of penetrating
item, the type of assembly being penetrated and whether the pene-
tration passes entirely through the assembly or through one mem-
brane or side of the assembly. It is also important to note that the
requirements of Section 714.5 apply to non-fire-resistance-rated
horizontal assemblies as well since openings through them can
also lead to the spread of fire, smoke or other hot gases to other
storeys or levels of a building. The IBC tends to view horizontal
assemblies as a way to compartment a building. Protecting pen-
etrations even in a non-fire-resistance-rated assembly will help to
provide protection and reduce the likelihood of a fire spreading to
other levels.
