Evacuation Modelling - Factor in Human Behaviour

Evacuation of buildings can be analyzed in different ways. Approved Document B (ADB) which provides guidance on meeting the requirements of the England and Wales Building Regulations with regard to fire safety, specifies width of exit routes such that the time required for occupants to flow out of a prescriptively designed enclosure, containing a maximum design population is 150s (2.5 minutes).


Mechanical Smoke Ventilation Systems (MSVS)

Until recently, prescriptive documents such as Approved Document B (ADB) and British Standards gave guidance on smoke control systems primarily by natural means (i.e. external automatic opening vents (AOV’s) and natural smoke shafts) and pressure differential systems (namely pressurisation systems).

Property and Business Continuity Protection in the UK

Building Regulations are intended to ensure that a reasonable standard of life safety is provided, in case of fire, and do not impose any requirements on the property and business continuity protection of a building.


Fire Safety in the Design, Management and Use of Residential Buildings - Code of Practice

The new code of practice for fire safety in the design, management and use of residential buildings BS9991 is published by BSI and came into effect on 31 December 2011.


Qualitative Design Review (QDR)

Qualitative Design Review or QDR is defined in PD 7974: 2001 as the initial stage of any engineering design in which the basic design parameters for a project are established and the scope and objectives of the fire strategy can be defined.


Water Mist Fire Protection in the UK

The use of water mist systems in the UK has increased over the last decade due to a number of reasons, the advantages being:


Fire Resistant Ductwork and Dampers

An important part of the infrastructure of a building is the ducting network that runs throughout the premises, it is often invisible, but is a key element to the environmental operations in a building.


The Building Regulations 2010

The requirements of Regulation 38 of the Building Regulations 2010 are those formerly covered under Regulation 16b and relate to the fire safety information to be provided by the person carrying out work.
