What Smoke Extraction Solutions are Chosen, According to Current Regulations
Since ancient times, humans have battled with their oldest invention – Fire.
Recent studies show that more than 85% of fire victims are caused by the smoke resulting from the burning of materials within the building. Thus, smoke extraction plays a vital role in ensuring the possibility of evacuating people under normal visibility and breathing conditions.
In case of fire, smoke extraction has a triple role. On one hand, through smoke extraction, air quality is ensured until people are evacuated. On the other hand, smoke extraction aims to create visibility in evacuation corridors. It should be noted that equally important is the fact that smoke extraction allows the evacuation of heat accumulated in the upper third of the building, which, if not released, can affect the roof structure.
Categories of Smoke Extraction Solutions
Smoke extraction elements are divided into two categories. Firstly, those that evacuate smoke, and those that introduce fresh air. It should be emphasized that regardless of how they are operated – manually or automatically, current regulations must be respected, specifically, EN12101-2 Standard.
For rapid and efficient smoke extraction, air intake is done through the lower part of the building located in the lower third. Also, according to P118/1999 Standard, air intake must be achieved through a surface of at least 60% of the smoke-extractable area.
KADRA proposes a series of smoke extraction elements with organized natural draft such as hatches and window actuations, as well as door actuations for fresh air intake, with which we can achieve a complete solution for evacuating hot gases with organized natural draft. Additionally, the smoke extraction solutions in KADRA’s portfolio also serve as daily ventilation.
About Smoke Hatches
KADRA hatches can be operated with Co2 gas or electrically, at 24V. The latter have the advantage of no maintenance costs and can have multiple roles, for emergency smoke extraction, daily ventilation, or access.
This category of hatches can be the perfect solution for residential buildings, where easy roof access and good ventilation are desired, as well as in case of fire, for effective evacuation of hot gases.
Moreover, you can enjoy natural light, and in this way, save on electricity. Due to very good thermal insulation, you will not have increased heat consumption and, implicitly, reduce thermal energy consumption.
How to Correctly Choose Smoke Hatches According to the Law?
