About WhitesalesWe specialise in the design, manufacture and installation of fully compliant smoke and access systems for all types of building.

Why performance in smoke control matters

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.

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.

Essential certificationAs life-saving devices, any natural smoke vent supplied must meet or exceed the BS EN12101-2 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.

The purpose of our smoke and heat exhaust ventilation systems (SHEVS) is to save lives by reducing the potentially fatal build-up of smoke and heat, leaving an area of breathable air above the floor.

LegislationApproved 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 12101-2 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 12101-2 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 7346-8 2013 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.

From July 2013 compliance with this CE Harmonised Norm became compulsory in the UK in terms of CPR Regulation No. 305/2011.

BS EN12101-1: 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 EN12101-2: 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.

ResourcesCAD 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.
