Topic of fire protection is now more relevant than ever. Every day, the news channels offer us the sad news about the large-scale fires that destroy property and take the lives of people. And the main cause of these accidents - neglect of safety standards and disregard for basic protection. The theme of this material from HouseShief.ru - modern fire protection of building structures. We will try to bring you all the most important information on this subject.

That includes the concept of fire protection?
Fire protection - it is quite a broad term that includes many important components. The first part of the complex - a modern alarm systems and fire fighting. Today, they are highly sensitive sensors which respond to the slightest risk. These sensors have already saved hundreds of thousands of lives, and refusing to install them, you are making a fatal mistake.
Barrier to the fire are the special chemical compounds, which process part of building structures. These are preparations, and composite materials.
These two steps, signaling and the processing in the complex provide a reliable guarantee fire safety of the building. Even if the fire for some time hosted in the building, and the fire is not immediately arrived at the distress signal himpreparatov as long as possible will protect the parts of the structure from the damaging effects, and you will spend much less time and money on recovery work.
Regulatory requirements for fire protection measures
The complex of works on fire protection shall be approved by another stage of preparation of the project design. Category of object and list of necessary measures set by SNIP 21-01-97 regulating fire safety of buildings, and NPB 105-95.
What is the fire resistance performance and how they are measured
The concept of fire-resistant material consists of the following characteristics:
- combustibility material;
- Flammability speed;
- fire spread across the surface;
- smoke formation during combustion;
- emission of toxic substances in fire.
Flammability Limit called time period which starts from the material withstands direct contact with fire and to failure.
What is the structural fire protection?
Structural fire protection - it is actually the construction of a barrier between the material you want to protect, and the possibility of fire. What can serve as such a screen:
- plastered or a layer concrete;
- refractory lining brick;
- the use of flame retardant screens;
- filling the inner space of non-combustible materials;
- engineering solutions to protect the nodes and connections.
Forms of passive fire protection
for the fire retardant treatment drugs are of three types: toothpaste, paints and impregnation. What they look like:
| Type of protection | Features of the application |
 | Are based on cement, Vermiculite or water glass. These compositions are placed on the details of construction dense layer. Use a similar protection for metal, concrete and brick. Such compositions are capable of withstanding a few hours of direct contact with flame. |
 | Have in their composition, flame retardants agents which, when the temperature is raised to 200 ° C begin to form a foam that lacks flames directly touch the surface. The process produces a gas which does not burn and acts as additional protection. Such paints also serve as decoration, have a greater colors and can be used for registration of premises on metal and wooden surfaces. |
 | Liquid impregnation use for wood, Fabrics and other surfaces with a porous structure. They may be superficial and penetrating, in most cases, are colorless. Upon contact with the fire in the treated material begins substitution reaction. Such as impregnation successfully prevents the growth of fungus. |
Do I need certificates for flame retardant substance?
Why is it important to use only certified flame retardants? If the composition does not have a fire safety certificate (SPB), the manufacturer does not guarantee the results you expected. With the same success you can paint the walls ordinary paint. If you like to entertain false hopes - in a good way. But if you are really worried about the security of their homes, buy only materials having the appropriate certificate, with the Russian sample.
That it should be specified:
- that may be protected by this composition (wood, metal or concrete);
- fire resistance of the treated material composition;
- the composition of consumption per 1 m square.
Note! On sale you can find generic formulations for the treatment of almost all types of designs.
In conclusion, we offer you a very interesting video in which using a torch trying to burn cardboard, covered with fire retardant paint.
conclusion
If you carefully read this material, we hope you have done all of the above, the right conclusions:
- modern fire protection should include a set of activities comprising setting alarm and fire processing means;
- to safely combine flame retardants: use of impregnation, paint and plaster;
- never neglect safety features, always monitor the integrity of the wiring and the safety of all carried out in-house work.
