Fire protection of ventilation system is a measure that prevents spread of fire, smoke and combustion products. Fire of ventilation system can cause rapid smoke spread and repeated ignition of combustion materials. Moreover, they also complicate carrying out rescue activities and increase damage. Therefore, before facility commissioning, it is necessary to carry out activities for fire protection of emergency ventilation system so that to increase resistance to ultra high temperatures.

important conditions of emergency ventilation is the ability to withstand t 600 °С. First of all, the following buildings need fire protection:
  • high traffic buildings – trade and entertainment centers, cinemas, business centers, educational institutions etc.
  • multi-story apartment buildings;
  • underground structures;
  • premises intended for storage of fuel and lubricants;
  • steel and chemical plants, plasma cutting and other industrial facilities.
Bath house, boiler house, rooms with fireplace also require fire protection system.

Which materials are used for fire protection of smoke exhaust ducts

  • mineral wool of any type;
  • special intumescent paints;
  • mastics;
  • thermal insulation barrier.
Fire protection of artificial ventilation involves the use of vibrationproof and soundproof materials, as such ventilation systems make noise and vibration during operation.

Basalt slabs

The common used materials for fire protection of vnetilation system are mineral wool, vermiculite, basalt, foil  and asbestos cement. Installation is carried out by means of screws, collars and wire. However, if the tubes are tightly adjoined the walls or located in the corner, this type of installation is not suitable. The reason is that the materials increase weight and size of tubes.

Paint and varnish

For protection of ventilation system, special paints and varnish which are intumescend under the influence of high temperature. Resulting coating has high thermal insulation characteristics. Disadvantages are high price and low yeld compared to other methods. Mastics Tubes are covered with mastic based on silicates, phosphates, mineral fibre nepheline. Recommended thickness of the layer is 10-50 mm. This method is affordably priced, effective and easy in installation. Nevertheless, mastic application is not such a simple process as it seems, that’s why it must be implemented by professionals.

Barrier

The following methods are used for creation of fire protection barrier: concrete coating, plastering and arrangement of concrete box. These methods are not so popular today, as they increase the weight and require accessory mounting. Before application of fire protection, it is necessary to clean, level and dry surface. Specialists of Server Service Company are well versed in smoke exhaust ventilation system. We design emergency ventilation systems, produce air ducts and carry out installation and commissioning works.

Fire protection of smoke exhaust ducts

Fire protection of ventilation systems – First of all, a measure that will prevent the spread of smoke, fire and harmful combustion products. Ventilation in case of fire contains two dangers – rapid spread of smoke and re-ignition of flammable materials. Both the first and the second not only complicate rescue operations, but also increase damage. That is why, when commissioning a facility, fire protection measures should be taken for the emergency ventilation system in order to increase its resistance to the effects of extremely high temperatures.

Which premises require fire protection first and foremost?

The gases released during a fire can reach critical temperature values. Of course, one of the most important conditions for the use of emergency ventilation– ability to withstand for minutes t 600 °С.

First of all, the following structures require fire protection:

1

Buildings with high traffic – shopping and entertainment complexes, cinemas, business centers, educational institutions, etc.

2

Residential multi-storey buildings;

3

Structures located underground;

4

Premises intended for storage of flammable and lubricating products;

5

Steel and chemical foundries, plasma cutting shops and other production facilities involving the use of open fire.

Household premises also require fire protection – boiler rooms, baths, rooms with fireplaces.

What materials are used for fire protection

To carry out fire protection measures, the following materials are most often used:

1

Mineral wool in any form (rolls or sheets);

2

Specialized intumescent paints;

3

Mastics;

4

Thermal insulation barriers;

5

Combinations of rolled insulation and paints.

Fire protection of forced ventilation involves the use of vibration-resistant soundproof materials, because such installations make a lot of noise and vibrate.

Basalt slabs

Fire protection is achieved by using mineral wool, vermiculite mats, basalt, foil, gypsum fiber cloth and asbestos cement. Installation is carried out using screws, clamps, wire. However, if the pipes fit tightly to the walls or are located in a corner, then this option will most likely have to be abandoned. The reason is that these materials increase the weight and size of the pipes.

Fire protection with paint and varnish

Special paints and varnishes that swell under high temperatures are often used for fire protection of ventilation. The resulting coating has high thermal insulation characteristics. The compositions can be applied without problems even in inaccessible places. The disadvantages include a high price and lower efficiency compared to other methods.

Mastic

The pipes are coated with mastics based on silicates, phosphates, mineral wool, and nepheline. The recommended layer thickness is 10-50 mm. This method is affordable, quite effective, and easy to implement. However, applying the mastic requires equipment, which means that such work should be entrusted to specialists.

Fire protection by creating a barrier

If a fire protection barrier is created, the following methods are used: concreting, plastering on a grid and arranging a brick box. These methods are gradually losing popularity, because they make the structures much heavier and require reinforced fasteners.

The fire protection compound “Fibrogein“, PROMATECT-L500 boards, Pirex paint, and Izovent rolls are especially popular. It is better to discuss the choice of one or another option with a specialist.

To apply any fire protection, it is necessary to prepare the surface – clean, level, dry. The glue is usually applied in two layers, the material – with a slight offset and also in two layers.
