This bulletin examines evacuation-modelling techniques and the use of one such programme, building Exodus. It reviews their use as a toll to determine possible areas, or deficiencies with a building and can be used to indicate where management procedures or actual structural building work could be necessary to assist in the building evacuation. The bulletin outlines the creation of the building model, the production and running of evacuation scenarios and simulations using the evacuation-modelling programme.
Establishing the correct level of expenditure for the design and installation of an alarm and detection system can be an extremely frustrating process. All professionals involved in this decision making process need to be aware of the fine balance between what is required in order to provide early warning in the event of fire and the cost against risk for life safety and property protection. In this edition we consider the cost of providing such systems and how to optimise those costs in order to get the best value for money.
Curiosity regarding the behaviour of fire in building elements dates back to the 18th century when professional engineers of the time became interested in fire safety. It wasn’t until 1918 however that the first standard was produced by the American Society for Testing and Materials (ASTM) specifically for the purpose of fire testing. It was this publication that paved the way for our own fire testing standards issued as BS 476 and first published in 1932. Soon after this, in 1935, the first fully equipped fire test laboratory in Britain was opened in Borehamwood Herts.
In this edition we look at atria in buildings and how BS 5588 Fire Precautions in the design, construction and use of buildings, part 7 "Code of practice for the incorporation of atria in buildings" aims to ensure that the incorporation of an atrium into a building does not present an increased risk to life as a result of fire and smoke spread.
In this edition we look at the latest documentation for fire safety engineering in the form of "DD240 Fire Safety Engineering in Buildings" and how fire engineering techniques can be applied to fire safety in building design by showing compliance with the levels of safety attained by using prescriptive regulations.
In many complex buildings which incorporate atria and large unprotected spaces, legislation and codes of practice often require some form of smoke control to compensate for the loss of protected escape routes.
For those involved in innovative or complex building design, the requirements to comply with BS 5588 and Approved Document B fire safety measures can often result in less than desirable design solutions. However an alternative to modifying design concepts is to utilise a fire engineered solution to acquire Building Control approval. Therefore in order to apply a fire-engineered solution it is essential that the designer understands the factors which affect fire growth and development.
Requirements for the provision of disabled access in buildings was first introduced into the Building Regulations over 15 years ago. Since then more detailed requirements have been incorporated in addition to other anti-discriminatory legislation, which place a statutory duty of care on building designers and occupiers to ensure that adequate measures are incorporated into new and existing buildings to enable the safe evacuation of people with disabilities.
