In many public buildings and commercial facilities, they are inconspicuous but of crucial importance: SHEV systems. But what exactly is behind the abbreviation SHEVS and what regulations need to be observed?
RWA: Meaning
The abbreviation SHEV system stands for smoke and heat extraction system. This is a technical system that is used to remove smoke gases and heat from a building in the event of a fire. On the one hand, this improves visibility for emergency services and people in the building and, on the other, reduces the spread of smoke in corridors and stairwells, which keeps escape and rescue routes clear. The main objective is therefore to ensure rapid evacuation in the event of an emergency and to minimise the extent of damage.
The importance of a SHEV system in practice
- Ensuring safety: The main function is to ensure the safety of people in the building in the event of a fire by dissipating smoke and heat to keep escape routes clear.
- Support emergency services: It facilitates the deployment of fire and rescue services by providing better visibility and accessibility to the interior of the building.
- Protect material assets: By dissipating smoke and heat, it helps to minimise property damage in the building and enable faster recovery after a fire.
SHEV system: Regulations in Germany
In Germany, SHEV systems are subject to various regulations and standards to ensure their functionality and safety. These include above all
- Building regulations: SHEV systems must comply with the building regulations in accordance with the state building regulations. These specify, among other things, in which buildings they are required and which requirements they must fulfil.
- DIN standards: Various DIN and VdS regulations are relevant for the planning, installation and maintenance of SHEV systems. These include DIN 18232 and VdS guideline 4020.
Other SHEV regulations also apply, such as the BetrSichV, the ArbSchG and accident prevention regulations.
Compliance with SHEV regulations is crucial to ensure the effectiveness of the systems and to save lives and limit property damage in the event of an emergency. Close cooperation between building owners, architects, specialist planners and fire protection experts is therefore essential when constructing and operating buildings in order to take the right measures and fulfil the legal requirements.
