A). BUILDING CODES AND FIRE SAFETY
As with any building element, the components of
structured cable management systems, such as
Resi-Gard raceways and accessories must meet the
requirements of the local adopted building code as
relates to their installation.
A primary issue addressed by building code regulation
involves fire safety in particular fire spread. Where
non-structural systems including those associated with
wiring, HVAC and plumbing systems, the codes address
them by insuring that the addition of these systems
does not unacceptably reduce the fire performance of
an assembly in which they are installed.
FIRES IN BUILDINGS
When early fire growth occurs, a fire that begins within
a room will not generally threaten cabling or wiring
installed in wall cavities until well after the whole room
is involved. There are two types of fires – differentiated
by their intensity as relate to fire growth - that occur
in buildings and their effects on wire and cable
installations are different.
Growth of a fire from a small, innocuous event to one
which threatens a room is divided into two regimes or
periods:
(a) The pre-flashover period.
(b) The post-flashover period.
During a pre-flashover fire regime or the pre-flashover
period of a fire, the physical boundaries of a room
