Smoke and heat exhaust ventilation systems
The smoke emitted by fires represents the greatest threat to people and the building. For this reason, it is extremely important that the smoke be extracted quickly and reliably. In this case, smoke and heat exhaust ventilation systems, as a fixed integral part of preventive fire protection, take over the most important task, namely discharging combustion gases, dangerous oxides and thermal energy outdoors in event of fire. Inn this way escape and rescue routes are kept virtually free from smoke, thus allowing active and passivle rescue. Furthermore, this avoids the thermal load imposed on the building structure by hot fire gases leading to damage to the building.
Smoke exhaust
Smoke exhaust refers to the extraction of smoke in the event of a fire (heat extraction), in order to create a low-smoke layer near the ground and thus enable the safe use of escape and rescue routes.
The products used here are safety-relevant building products that are regulated by EN 12101-2 in Building Rules List B, part 1.
In these cases, NSHEV are required as part of SHEV.
Areas of application:
- Public assembly places
- Large warehouses
- Industrial buildings
Smoke ventilation
Smoke exhaust systems in stairwells are referred to as smoke ventilation. Their purpose is to extract smoke by way of cold smoke exhaust. The products used here are non-safety-relevant building products that are therefore only listed in Building Rules List C, part 3.10.
Planning takes place in accordance with the specifications of the respective applicable regional building regulation (LBO). Crucial aspects include the location, size and opening width of the smoke exhaust apertures, as well as the number and location of automatic and manual alarm devices.
Areas of application:
- Stairwells
