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.
