SE Controls has over 25 years experience of working with clients through every step of the construction process, delivering designed, installed and maintained smoke and heat...

Principles of Smoke Ventilation

Smoke ventilation allows the creation of a smoke free layer above the floor by removing smoke. This improves the conditions for safe escape and permits the fire to be fought in its early stages. What happens if there is no means of smoke ventilation? 1. In an unventilated room, smoke will rise directly to the ceiling. 2. The smoke will begin to fill the space available moving laterally instead of vertically. 3. Convection of the smoke will cause it to be drawn back down to low level reducing visibility and the chances of a safe escape. 4. Temperatures will continue to rise causing the potential...

Core Competencies – The Total Solution Fire Engineered Solutions The design of smoke and heat exhaust ventilation systems (SHEVs) falls into two distinct areas, namely those systems complying with building regulations and those systems requiring a fire engineered solution. SE Controls is able to offer both. It is not always possible to apply a code compliant or prescriptive solution to every scheme. When this occurs, Approved Document B (ADB) allows the designer to step away from ADB and provide a Fire Engineered Solution. As a Fire Engineered Solution will be dealing with many unknown factors,...
