fire takes hold in building, quite apart from ensuring early warning
and the safe evacuation of all persons, and informing the fire brigade
there are a number of things to bear in mind. These include:
- Extreme heat
causes distortion of e.g. doors, and melting and distortion of
e.g. service pipes, and the heating and combustion gases which
rise towards the ceiling area.
gases and smoke (hot and cold) can spread quickly between spaces,
rooms, corridors and floors as the hot gases flow from high pressure
to low pressure. These gases, the smoke and flames can therefore
travel more easily and quickly through surfaces where there are
gaps, a lack of integrity / where the integrity of a surface has
been breached and / or not properly protected in the first place.
Smoke, and gases can also spread quickly through any other (necessary)
gaps between spaces, rooms, floors and ceilings e.g. ventilation
systems, pipes, electrical trunking, lights etc.
- Fire will
more easily be able to attack other areas where a building structure
is vulnerable e.g. gaps behind door frames, recessed switch and
socket boxes etc.
- Electro mechanical
devices cannot be totally relied upon as a sole means of controlling
the spread of fire, heat gases and smoke because these devices
may not function correctly because e.g. they are distorted or
damaged by heat or their power supplies are damaged.
It is clear
from these points that a specialised and failsafe method of protecting
from and slowing the spread of fire, smoke and gases as well as
meeting building regulations needs to be easily incorporated in
a building's structure either from its initial construction, or

material reacts to the levels of heat generated by fire by expanding
to many times its own size. It also creates a large amount of char
which can have a choking and stalling effect on the flames that
are trying to find a way from one space to another. The expanding
reaction means that during a fire it fills gaps and spaces and closes
off pipes, ducts, trunking, door frames and any other spaces that
may allow fire to spread, thus containing the spread of the fire.
A wide variety of specialised products are available to cover all
aspects of building protection - click the links on the left hand
side for detailed information about each. Examples of these products
and Smoke Dampers - These compact and lightweight
dampers can be fitted into ventilation systems. They require minimum
maintenance, are very cost effective and provide a great line
Upgrading - Fireplug CFPM intumescent paper, ICT
water based acrylic and TSC sealing coat (to protect the other
layers) can be applied to a timber door to improve its fire resistance.
Fireplug Intumescent Strips can be applied to the edge of the
door and the door frame, and intumescent fire seals can be fitted
to the back of door frames.
- These can be used to replace and non fire resistant grills e.g.
doors, ventilation ducts, stud walls etc. They will expand and
close of these potential route for rapid spread in the event of
These are installed around PVC pipes. When the pipe melts in a
fire the intumescent material expand to fill and close the gap.
Pipe Canisters / Pipe Closers
These are metal canisters filled with intumescent material that
are used where a pipe reaches a wall or ceiling.
Retardant Coatings, Paints
and Varnishes - The various types can be applied
to timber, particle boards and steel.
- These consist of intumescent material that is enclosed in
foil and is attached to the inside of electrical trunking. The
intumescent material expands ton close the gap in the trunking
under the effects of the heat form the fire.
Passthroughs - Fireplug Cable passthrough (CPT) and
(CPTC) provide protection where cables pass between e.g. walls,
floors and suspended ceilings.
/ Switch Box Covers - These provide intumescent protection
where switch and socket boxes have been recessed into walls.
and Locks - Fireplug CFPM Intumescent membrane Paper
can be used to protect locks and hinges. The overall integrity
of a door against fire means looking at all potential gaps or
