MODERN FIREPROOFING TECHNIQUE

Definition of Fireproofing

Fireproofing is the process of building the incombustible or fire resistant quality of any structure or material by implementing some methods. Thus, it will provide the ability to withstand the structure in high temperature for longer time. It is a passive from of fire protection measure.

Based on what kind of method has been applied from the certification listed for fireproofing and on which type of structure, a fire resistant rating is inscribed. Fireproofing does not indicate that that structure will not burn or have any effect on fire at all. Rather, it is the mean to lessen the effect of fire and thus to buy some times in emergency situation to save some more lives. It is a certain amount of ability to withstand fire.

Methods of Fireproofing

Some methods of fireproofing are like poured-in-place concrete, gypsum plasters, cementitious plasters, fibrous plasters, light weight cement, prefabricated cementitious board, the intumescent coating is so on. Fireproofing is designed for the protection of the structures which sustains highly risky or valuable materials. But it has become popular in other areas like offices, industries, factories and so on.

Spraying Method

One method of emergency fireproofing is to spray fireproofing materials between metal structure and fire so that the metals can absorb less heat. Thus, some more time can be extended, and more life can be saved. Spraying fireproofing is also helpful in case of wood, fabrics and structural steels.

Absorption Method

A very popular method used in textile miles for fireproofing is using some fire retardant solutions. Materials are drenched in the solution and after absorption, it is then dried. A solution of boric acid and borax can be used for interior materials and solution is composed of chlorinated paraffin can be used for exterior purposed.

Using Gypsum

A very popular method is to use gypsum or parts plaster as passive fireproofing products. This plaster can slow down the spread of fire as it releases vapor when it comes contact with heat. It also works as a heat insulator for the structure.

Cementitious Fireproofing is a mixture of wet plaster with Portland cement or gypsum as it’s base. For steel, it has a fire resistant rating of 1 to 4 hours. Another method is using fibrous plaster. It is gypsum plaster that is reinforced with sisal or canvas. As it contains mineral wool or ceramic fibres, it retains much air that works as an insulator.

Liquid Convection Method

Liquid convection cooling in hollow structural members is an alternative method to keep the structural steels below the softening temperature. Thus, it can control the temperature of the structure steels.

Painting Method

Over the painted surfaces some fireproofing coating, fire retardants or intumescent paint can be applied. Thus, the surface will get a higher level of resistance against heat. Fire proofing is very much important. The user has to very selective to choose structure and materials used for housing. The consulting with some expert of this field should be a must for a proper and efficient selection in time of construction for making the building a more safe property.
