Fireproofing is the act of protection done to prevent a substance, or a
building from catching fire in case of any natural calamity or any disaster
that may strike. This renders combustible material temporary properties to make
then non-combustible. Fireproofing
is of a preventive nature to avoid damage
to either men or materials.
Fire
retardant materials are used in the process of fireproofing any material or
buildings. Fire retardant materials burn slowly, and hence, prevents damages. Some of the fire retardant materials are Rock wool, Gypsum boards,
Modacrylic, Asbestos cement, Perlite boards, Proplex Sheets, Calcium
silicate boards, Kevlar, Treated
lumber plywood, Carbon Foam, Twaron, Treated vegetable fiber (
for e.g. Jute, Cotton, Kenaf, Flax, Hemp, etc..),
Arselon (Khimvolokno trademark), M5 fiber, Brick, Fire-retardant-treated wood, Technora, Cement render, Concrete, glass,
Intumescent paint, PBI, Buren stop, Nomex (DuPont trademark), Pyrovatexfr Cotton,
Wool,
coated nylon, etc.
Fire proofing is done basically in
buildings and for textiles on a large scale
since these things are very combustible and can add to a great loss.
Making
the buildings fireproof
The wood which is used in the building
to give the infrastructure a framework
and support is not much affected in fire
since it comes in the inner part. Thus, to retail this framework, the wood used
in construction is treated with special materials so as to prevent or slow down
its combustion in case of fire break out. They are treated with special
mastics, stucco, ammonium phosphate solution or other incombustible facing before or during the construction itself.
Though in modern constructions we find
the use of concrete and steel, they also
tend to burn and cause damage. Therefore, stringent rules have been put in place to fireproof them. The concrete construction
should be reinforced and protected steel is advised to be used to classify the
buildings as fire resistive. To protect steel, it advised to cover it with bricks, tile or concrete, but they add to
the existing weight of the building and make the foundation bear a lot of weights. To avoid this mineral fiber
gypsum, vermiculite, and Perlite are used. They are light weight as well as
give adequate fire proofing properties.
Water circulation is also one way to stop the meltdown. Fire proofing is to be
done equally on the outside of the building as in the inside, to protect the
surrounding buildings.
Textile
fireproofing
Many types of fabrics are used in the building
and they tend to catch fire more easily.
It is the second most reason for fire catching
after electrical short circuits. To prevent this
from happening, fabrics are soaked in
different materials to make them fire resistant. But this is a very small measure
since the chemicals can be washed off or
evaporates, and again make the fabrics combustible. Some of the chemicals used
to make textile fire proof are boric acid, borax, chlorinated paraffin,
chlorinated synthetic resins and chlorinated rubber. To make them more permanent in mature, latex is added which gives
them a high fireproofing ability. Textiles may also be sprayed and brushed with
fireproofing chemicals at regular intervals to maintain already existing
fireproofing for a longer duration.
