CHAPTER 2
Firestop & Its
Applications
(Fig 2.1)
In virtually every building, the fire-resistance-rated and/or smoke-
resistant assemblies are penetrated by pipes, cable trays, vents,
tubing, wiring, conduit and ductwork so that building systems can
be installed, and the building can serve its intended function. When
this is done the building compartmentation gets breached which
forms the point of non-compliance and these breaches can become
a threat to life and property safety if unsealed by approved firestop
systems.
In India, NBC 2016 recommends the sealing of breaches created
by low voltage cables, electrical cables, pipes, ducts and shaft
sealing, etc. under multiple clauses. However, it does not give very
comprehensive detail in the 2016 edition.
