SMOKE CONTROL ASSOCIATION
Statement from the Smoke Control Association on the Grenfell Tower fire
The Smoke Control Association (SCA) would like to pass on their heartfelt condolences to the families of those that tragically lost their lives in the Grenfell Tower fire on 14th June 2017. We would also like to express our upmost respect for the [.. more]
The importance of a well-designed smoke control system
If there is a fire, a well-designed smoke control system can save lives and help protect property. It will:
- Keep escape and access routes free from smoke.
- Facilitate fire-fighting operations.
- Delay or prevent flashover, reducing the risk of the fire developing further.
- Protect the contents of the building.
- Reduce the risk of damage to the building.
Some different types of smoke control systems
Smoke and Heat Exhaust Ventilation Systems (SHEVS). Whether these are natural or powered, they remove smoke from the building. Inlet ventilators, dampers and ductwork are also often integrated into the scheme.
Smoke Containment Systems. These prevent the movement of smoke and heat from one area to another. They take the form either of physical barriers such as smoke curtains or fire curtains, or as pressure differential systems, also known as pressurisation systems.
Car Park Ventilation Systems. Induction (or jet) fans clear smoke from enclosed or underground car parks. These are often combined with fume ventilation to prevent the build-up of vehicle exhaust gases in normal day to day use of the car park. Louvres, dampers, and powered smoke extraction fans are also often integrated into the scheme.
The chairman of the Smoke Control Association says: “Smoke is the greatest threat in a fire. A fire can fill an area of 10,000m2 with smoke within minutes. 5 breaths are all it could take to lose consciousness. Effective smoke control saves lives”.
Membership of the Smoke Control Association (SCA)
Membership is open to any company or organization involved in the manufacture and supply of smoke control equipement and systems.
A list of member companies can be found by clicking the Members List
Members are also listed in the broader Directory of HEVAC companies.
The aim of the group
To represent and promote the UK smoke control industry. The membership can be relied upon to provide impartial guidance. Click here for a brief description of the SCA and the work it does.
FIRAS Scheme for Smoke Control System
In July 2012 the first certification scheme of its kind for smoke control systems was announced by Warrington Certification Ltd working with the Smoke Control Association.

NEW - SCA Guidance Note for the use of Inverters or Variable Speed Drives in powered smoke ventilation systems - 29 Sep 2016
This one-page guidance note is intended to help designers, specifiers, approval and regulatory bodies satisfy themselves that the control systems and strategies proposed and installed are appropriate for the specific application. Download here
The guidance refers to the GAMBICA Guide - Fire Mode in Variable Speed Drives
GAMBICA Guide - Fire Mode in Variable Speed Drives
This Guide is to provide a reference for Variable Speed Drive (VSD) manufacturers and users to establish criteria by which Fire Mode in VSD should be defined. This is to enable a common understanding of what Fire Mode is and clear communication of how any specific product operates.
Guidance on Smoke Control to Common Escape Routes in Apartment Buildings (Flats and Maisonettes)
- First published Nov 2010; Revision 1 published 14 June 2012; Revision 2 published on 12 Oct 2015
The prevention of smoke spread through buildings is of critical importance, but little guidance is currently available in one publication. This document provides details and gives recommendations not previously covered in other standards or codes of practice and should make a significant contribution to improved understanding of smoke control systems.
Revision 1 (201) includes amendments to clauses 220.127.116.11, 6.4.1, 8.2.12, 9.3.3 and 9.3.4 to reflect recent changes in best practice and the publication of BS 9991.
Revision 2, published on 30 Oct 2015, contains many new recommendations, updated product standards, a new section on Fire Service Intervention and a limitation on the extension of travel distances to which all member organisations have agreed.
CFD Modelling for Car Park Ventilation Systems – a guide for designers and regulators - Feb 2007
This document sets out the information and parameters that the designer should incorporate into the design of the CFD model. It is intended that this document should be of use to the designer in producing and running the CFD model and in writing the CFD report. It also provides recommendations on the information to be provided to the approving authority within the designer’s package of supporting information when submitting the CFD analysis for information and/or approval of design intent. The Smoke Control Association is primarily concerned with ventilation design for the removal of smoke and heat as discussed in the British Standard, but, recognising the dual use of systems, this document provides guidance on usage for both smoke and heat removal and vehicle emission ventilation. This document is intended to support the recommendations of BS 7346-7.
Design of Smoke Ventilation Systems for Loading Bays & Coach Parks – a guide for system designers- Nov 2010 This document sets out to give guidance to the design of ventilation systems for loading bays, service yards and coach parks and lists the options available to the design engineer. This document should also be of assistance to the regulating authorities in assessing the suitability of systems submitted for their approval.
DIRECTORY OF STANDARDS
The directory of standards lists the various associations within FETA and the standards that are appropriate to those parts of the membership. Also included are the various BSI committees that have responsibility for each standard. The directory was compiled by Ian Andrews Associates, specialist in directives, regulations, standards and legislation for the appliance and ventilation industries. Available as a free download to FETA members.
