Statistics from the Department for Communities and Local Government reveal that 53% of all fire-related fatalities result from people being overcome by smoke or gas, rather than dying from the fire itself. Smoke vents are life-saving devices that greatly increase occupants chances of survival in the event of fire. Essential certification As life-saving devices, any natural smoke vent supplied must meet or exceed the BS EN standard. This involves passing rigorous testing against strict criteria for: Determination of aerodynamic free area Reliability Opening under load Low ambient temperature Wind load Heat exposure All NSHEVS manufacturers products must pass stringent tests carried out by a fully independent test laboratory. As well as keeping escape and access routes smoke-free, SHEVS delay or prevent flashover to slow or stop fire developing to devastating levels. They help firefighters tackle blazes more safely, effectively and quickly, so they can save more lives and reduce structural and material damage to buildings. Always look out for the compulsory CE mark, be sure to obtain your declaration of performance from the manufacturer and carefully examine your products before installation. All Whitesales smoke and access products are designed and manufactured to ISO 9001, CE marked and fully certified, and meet the requirements of Building Regulations ADB and ADL.

14 Design considerations Certification BS EN12101 Smoke and Heat Control Systems From July 2013 compliance with this CE Harmonised Norm became compulsory in the UK in terms of CPR Regulation No. 305/2011. BS EN : 2006 Specification for Smoke Barriers This standard details the function, types and applications of smoke barriers, including their performance and classifications. Tests include reliability, durability, response times, permeability, fire resistance and deflection under load. BS EN : 2017 Natural Smoke and Heat Exhaust Ventilators This standard describes natural smoke and heat exhaust ventilators (SHEV) as a system of safety equipment intended to perform a positive role in fire emergency by creating and maintaining a smoke free layer above the floor by removing smoke and simultaneously exhausting hot gases released by the fire in the developing stages. The document details a series of tests intended to establish that these SHEVS will operate fully and reliably whenever called upon to do so during their installed life. There are six tests which must be carried out by an independent laboratory: determination of the aerodynamic free area; reliability; opening under load; low ambient temperature; wind load; and heat exposure. These are all carried out in laboratory conditions. The key point is that the smoke ventilator must meet a certain aerodynamic free area value which is related to the geometric area and the coefficient of discharge. This means that the regulation not only requires the rooflight to be a certain size and open to a minimum of 140, but also that the aerodynamic area of the opening meets the required standard. The smoke vents specified must all have a Declaration of Performance, which is a certificate that confirms the test results. All approved products need to have correct labelling stating the results of the tests, name of manufacturer/supplier, year of manufacture, and the aerodynamic area. This helps to provide traceability for the customer. BS EN : Specification for Powered Smoke & Heat Control Ventilators (Fans) This standard details testing and assessment of smoke and heat extraction by powered systems. Tests include reliability, response times, resistance to fire, and effectiveness of smoke and hot gas extraction. BS EN Installed SHEVS systems for smoke and heat ventilation. BS EN Guidelines on functional recommendations and calculation methods for smoke and heat exhaust ventilation systems. BS EN : 2005 Specification for Pressure Differential Systems - Kits BS EN :2011 Smoke Duct Sections This standard details construction of components used in single and multicompartmented smoke control ducts and tests include fire resistance, integrity, insulation and leakage. BS EN :2011 Smoke Control Dampers This standard describes the construction and operation of smoke control dampers. Tests include fire resistance, integrity, insulations, leakage, durability and response times. In addition aerodynamic performance and resistance to corrosion are evaluated. pr EN : 2004 Control Panels This European Standard specifies the product performance requirements, classifications and test methods for control panels, designed for use in smoke and heat control systems in buildings. At the time of printing this document was still in draft awaiting adoption by all member countries. BS EN : 2005 Power Supplies This standard details power supply for a primary and secondary electrical system, and pneumatic equipment. Products include mains electrical, batteries, generators and compressed gases. Tests include operation in damp and cold conditions. Evaluation also includes factory production control. Legislation Approved Document B 2006 Fire Safety For smoke ventilators, Approved Document B states that the free area of a smoke ventilator may be measured by either the aerodynamic area in accordance with the EN or the total unobstructed at cross sectional area measured in the plane with areas at a minimum and at right angles to the direction of air flow. There is nothing in Approved Document B to specify a specific opening angle for smoke ventilators; however if they open to anything less than 90, this would affect the air flow calculation. Approved Document B only requires the rooflights to finish 150mm above finished roof level, but EN states that it must be a minimum of 300mm. The Regulatory Reform (Fire Safety) Order 2005 The aim of this reform is to simplify, rationalize and consolidate existing legislation. This provides a risk based approach to fire safety allowing a more efficient and effective enforcement by the fire and rescue services and other enforcing authorities. Among many other things it details the responsible person and the duties imposed on them including general fire precautions, risk assessments, fire-fighting and emergency routes and exits. Guidance BS Guidance Components for Smoke Control Systems Part 8: Code of Practice for Planning, Design, Installation, Commissioning and Maintenance. This British Standard gives recommendations for the planning, design, installation, commissioning and maintenance of smoke control systems, including smoke clearance, in and around buildings. The recommendations are applicable to systems intended for the protection of life and/or protection of property, including: a) natural smoke ventilation; b) mechanical smoke ventilation; c) smoke barriers; d) smoke and heat exhaust ducts; e) smoke dampers, and their controls, power supplies and interconnections. This British Standard is not applicable to non-fire-related functions of smoke control systems. This British Standard does not give recommendations as to whether or not to install smoke control systems in any given premises BS9999. This British Standard gives recommendations and guidance on the design, management and use of buildings to achieve reasonable standards of fire safety for all people in and around buildings. It is not applicable to individual dwelling-houses, and might have only limited applicability to certain specialist buildings and areas of buildings (e.g. areas of lawful detention). BS Fire Safety in the Design, Management and use of Residential Buildings This British Standard gives recommendations and guidance on the design, management and use of residential buildings. It covers dwellings, residential accommodation blocks and residential housing. It applies to the design of new buildings and material alterations and extensions to existing buildings. Its intentions are to safeguard the lives of building occupants and fire-fighters. BS Fire Safety in the Design, Management and Use of Buildings This British Standard gives recommendations and guidance on the design, management and use of buildings to achieve reasonable standards of fire safety for all persons in and around the building. It is a comprehensive document covering design of buildings, fire protection, means of escape, access and facilities for fire-fighting personnel and management of risk assessments of occupied buildings. Resources CAD Computer Aided Design CAD is used to create precision technical documentation, using either 2D line drawings or a 3D modelling format. 2D drawings can be considered as electronic paper, using lines to represent geometric data which carries only dimensional and annotative information. 3D modelling on the other hand, is used to represent full engineering details of a product, capturing all aspects of a design, from geometric data to integrated business processes. BIM Building Information Modelling BIM is a digital representation of physical and functional characteristics of a project. It is a shared knowledge resource for information contained within the project, allowing for the management of processes and information throughout its life cycle; defined as existing from earliest conception through to demolition. Schematics Schematic wiring diagrams are a pictorial way of showing electrical circuit, and its simplified pictorial representation shows the components and power and signal connections between the devices. Whitesales provide wiring schematics for all smoke control installations detailing cable size, core quality and programming information. CFD Computational Fluid Dynamics CFD uses numerical analysis and data structures to solve and analyse problems involving fluid flow. It is used extensively in fire modelling to predict the development of fire in a building. Results are used to determine location and specification of smoke control.
