In addition, the application of the markings may have been forgotten
or not assigned, which would be a code-compliance deficiency that
should be noted and corrected. The most reliable reference to consult
in establishing which walls are supposed to be fire-resistance-rated
and which are not is the design documents.
Where an accessible concealed space is provided in areas adjacent
to firewalls, fire barriers, fire partitions, smoke barriers, smoke
partitions or any other wall required to have protected openings, there
must be a means of marking the wall so that it is clear that openings
through it must be protected See Figure 101 for an example of this
requirement. This allows building maintenance workers, contractors
and inspectors a quick visual reference that they need to ensure that
any penetrations or openings are protected. Further, in situations
where a phone technician, cable installer or I.T. wiring person pokes
a hole in the wall, they will be alerted that someone must provide a
firestop system or other means to restore the assembly to its original
condition.
