Fire retardant treatment of wooden attic constructions: features

Attic is one of the most flammableplaces in any building. After all, it is here that the most complex assemblies of wiring from around the house are concentrated. Occurrence of the slightest closure represents an extreme danger for the object. That is why the timely fire retardant treatment of wooden constructions of attic premises is so important. Let's figure out what are the features of the implementation of such events.

What is the purpose of applying fire retardant coating on wooden structures?

Thanks to the fire protection of attic floors, the following tasks are solved:

• accidental fires are prevented;
• Potentially dangerous factors are weakened, the effect of which can lead to a fire;
• slowing down the development of ignition in the initial stages;
• an open flame is localized.

Primary requirements

Is fire retardant treatment of wooden constructions of attic premises of buildings mandatory? This is what the state building codes say about this.

According to the provisions of SNiP, fire protection treatmentWooden constructions of attic premises should be held in places between the roof and the floors. The application of fire fighting compounds is mandatory for rafters and crates.

Even from several small excerpts it can be judged that fire retardant treatment of attic rooms is an obligatory precautionary measure when putting the facility into operation.

Additional requirements

Among the optional measures to protect attics from fires, it is worth noting:

1. Installation of fire hatches - act as a means of emergency access to the attic and make it possible to keep the spread of open fire up to 30 minutes.
2. The creation of special cuts is an effective solution that allows to stop the rapid ignition of floors by dividing the area of ​​the attic into separate sections covered with non-combustible materials.
3. Observance of the rules of operation of the premises - it is forbidden to accumulate garbage, clutter up space near bearing structures.

Classification of fire protection means

Specialized tools that are used inFirst of all, fire safety measures are divided into solid and liquid categories. The first, in turn, are divided into superficial and deeply penetrating. Solid compositions with the help of which fire retardant treatment of wooden attic constructions is possible include all kinds of dusting and coating.

According to the nature of the action, all fireproofthe means are divided into passive (prevent the influence of high temperatures on the deeper layers of materials) and active (directly affect the combustion process).

How is the fireproofing of the wooden constructions of the attic premises made?

Activities aimed at protecting roof slabs from fires are realized by employees of specialized services on the basis of a relevant license. During the works:

1. The calculation of the area of ​​the premises is carried out, which makes it possible to reduce the risk of fire, based on existing conditions.
2. There is an audit of the structure for compliance with the priority requirements that are required for fire-fighting attics.
3. Determine the necessary fire protection measures.
4. It is applied the application of liquid formulations or solid materials to the floors, taking into account the required class of fire-fighting treatment.
5. Examination of the quality of work is carried out, a relevant act is drawn up.
6. Confirming papers are presented to the owner of the object.

Means of fire protection

What are the materials for the fire protection of attics? Currently, several options for fire protection are used.

First of all it is necessary to allocate paint and varnish. This includes all kinds of non-combustible mastics, paints, varnishes, impregnations. The coefficient of refractoriness of such products is indicated on the packaging.

Treatment with fire retardant woodloft designs may adversely affect human health. Therefore, the mandatory requirement for the application of liquid paints is the use of personal protective equipment.

For fire protection of load-bearing structures more oftenresort to the creation of special fire-resistant barriers in the form of plasterboard or gypsum fiber boards. The internal space between the materials is filled with non-combustible mineral fillers.

As an alternative for protectionattic floors can be used more reliable, but at the same time, costly solutions, such as roll materials and liquid formulations based on vermiculite.

According to the rules of fire safety,these measures with the use of refractory means can be performed independently by the owners of the facility. However, in practice, such actions are extremely negatively considered by representatives of the Ministry of Emergency Situations. In order to avoid trouble, work aimed at fire protection attic space, it is recommended to conduct at least under the supervision of a fire inspector.
