No compartments or dividing walls Unlike ducting, thrust ventilation allows the construction of enclosed car parks that have an open, clean and safe environment without compartments or dividing walls. The exhaust air is extracted using the main exhaust extract fans. The air flow is determined by the current regulations for car park ventilation systems BS — and Approved Documents B and F. In the case of fire, visibility of at least 30 metres should be provided minutes after the fire has started and this is often examined and proved by the use of a CFD model at the design stage. Should this not be practical, supply air will need to be introduced mechanically. Thrust ventilators use this natural property of propulsion to accelerate the maximum mass of air and this is the force we measure in terms of Newtons, with fans that are multi-speed and supplied in either 50 Newton or Newton versions.

BS 7346 Part 8 standard for smoke ventilation systems is a crucial life saving requirement
BS Part 8 standard for smoke ventilation systems is a crucial life saving requirement 15 Aug However, while Building Regulations Approved Document B, The Machinery Directive and The Construction Product Regulations, via the various parts of EN , provide a relatively tight regulatory framework, until the BS Code of Practice, no single document existed that provided guidance for the industry from initial design, through installation to maintenance. The over arching benefit of this new document is that by adhering to its guidelines designers, installers, commissioning engineers and maintenance teams can create, install and operate a fully compliant smoke control system. Throughout BS , there are some constant themes that are present. Not only does it deal with product quality, location, performance and operation, but also the key questions of assessment of needs together with the certification and verification by authorised bodies. Developing the standard The Smoke Control Association SCA , of which SE Controls is a long-standing corporate member and has been present on the British Standards committee for more than 15 years, recognised that there was a need to raise the standards across the industry. A key driver in the early stages of the process was evidence suggesting that smoke control systems in residential high-rise developments were of variable quality, an issue created by a number of factors.
