Smoke and heat extraction systems remove smoke and heat from burning buildings. This keeps escape routes and access routes for the fire department smoke-free.
What are the advantages of a natural smoke and heat extraction system?
Emergency safety. When drawing up an emergency plan to take effect in the event of a fire breaking out in the building, particular attention must be paid to the risk of asphyxiation due to the inhalation of smoke gases. Smoke must be dissipated from the building as quickly as possible in the event of a fire so that building occupants can safely use escape routes and firefighters can safely and effectively fight the fire.
What is natural smoke and heat ventilation?
A natural or passive smoke and heat exhaust system is characterized by the fact that smoke is quickly removed via automatically opening windows at higher points and, at the same time, outside air flows in via lower-positioned inlet openings. This enables reliable smoke removal and fresh air supply.
Natural smoke and heat extraction also prevents the building from overheating. This helps to prevent smoke explosions.
Regular maintenance of SHEV systems is essential
(16.8.2011) Reliable SHEV systems are used to quickly and effectively remove smoke from buildings and must be regularly maintained and repaired to maintain their functional safety. If the legally prescribed obligations are neglected, building owners or operators face both civil and criminal consequences. The most important normative regulations – DIN 57833, 18232 and 31051 – as well as VdS/ CEA Guideline 4020 of VdS Schadenverhütung are intended to ensure effective fire protection.
