the design and construction of the drainage for a building<br />
may be of any type, but it must be adequate.<br />
In the same way, the regulations relating <strong>to</strong> the fi re<br />
safety of buildings are not in the main prescriptive but<br />
outline certain functional requirements, for example<br />
the Building Regulations require that all buildings have<br />
‘appropriate means of escape in case of fi re’.<br />
The Building Regulations are enforced by local<br />
building control authorities, which work under the<br />
auspices of the government department responsible for<br />
planning. It is the local building control authorities who<br />
normally decide whether or not a particular approach<br />
<strong>to</strong> satisfying the functional requirements of the Building<br />
Regulations is adequate.<br />
In order <strong>to</strong> provide some helpful guidance <strong>to</strong> designers<br />
and construc<strong>to</strong>rs, the DCLG issues detailed guidance<br />
on how the functional requirements of the Building<br />
Regulations may be met. This detailed guidance takes<br />
the form of ‘Approved Documents’; these documents<br />
have the same status as all approved Codes of Practice.<br />
In the case of fi re safety DCLG have issued ‘<strong>Fire</strong><br />
<strong>Safety</strong> – Approved Document B’ <strong>to</strong> the Building Regulations<br />
2000 (Revised 2006).<br />
The Building Regulations are divided in<strong>to</strong> various<br />
‘parts’. Part ‘B’ of the regulations deals with the main<br />
fi re safety requirements for all buildings.<br />
There are two volumes:<br />
➤ Approved Document B (<strong>Fire</strong> <strong>Safety</strong>) – Volume 1:<br />
Dwellinghouses (2006 Edition)<br />
➤ Approved Document B (<strong>Fire</strong> <strong>Safety</strong>) – Volume 2:<br />
Buildings other than dwellinghouses (2006 Edition).<br />
Part B of the regulations is further subdivided in<strong>to</strong> the<br />
following fi ve sections:<br />
➤ B1 Means of warning and escape<br />
➤ B2 Internal fi re spread (linings)<br />
➤ B3 Internal fi re spread (structure)<br />
➤ B4 External fi re spread<br />
➤ B5 Access and facilities for the fi re service.<br />
Table 9.1 provides a summary of the functional requirements<br />
of the regulations relating <strong>to</strong> fi re safety.<br />
In addition <strong>to</strong> ‘Approved Document B’ the Building<br />
Regulations also provide direction on ‘access <strong>to</strong> and use<br />
of buildings’ in ‘Approved Document M’ for all persons,<br />
but particularly those with disabilities.<br />
The Workplace (Health <strong>Safety</strong> and Welfare) Regulations,<br />
Disability Discrimination Act and Discrimina tion<br />
(Employment) Regulations all require arrangements <strong>to</strong> be<br />
established <strong>to</strong> ensure all persons can safely gain access<br />
and use facilities and do not differentiate these requirements<br />
from those required in the event of an emergency.<br />
<strong>Fire</strong> protection in buildings<br />
Thus due consideration must be made when accessing<br />
the requirements for those with disabilities.<br />
9.4 Building construction and design –<br />
preventive and protective measures<br />
Designing and maintaining a ‘safe’ building is the fi rst<br />
step <strong>to</strong> ensuring reasonable levels of fi re safety for the<br />
building and its occupants in the event of a fi re. Without<br />
a safe building, all the efforts of management <strong>to</strong> provide<br />
systems that prevent fi res occurring or ensure emergency<br />
evacuation will be of little or no effect. The fundamental<br />
features that provide a basis for both building<br />
and life safety in all buildings are:<br />
➤ Elements of structure<br />
➤ Compartmentation<br />
➤ Internal linings.<br />
9.4.1 Elements of structure<br />
An element of structure is defi ned as being part of a<br />
building, which supports the building, i.e. a load-bearing<br />
part, for example:<br />
➤ Any part of a structural frame (beams and columns)<br />
➤ Any load-bearing wall (other than part which is only<br />
self-load-bearing)<br />
➤ A fl oor or any element that supports a fl oor.<br />
A roof structure is not considered as an element of<br />
structure unless the roof provides support <strong>to</strong> an element<br />
of structure or which performs the function of a fl oor.<br />
The elements of structure should continue <strong>to</strong><br />
function in a fi re. They should continue <strong>to</strong> support and<br />
maintain the fi re protection <strong>to</strong> fl oors, escape routes and<br />
access routes, until all occupants have escaped, or<br />
have been rescued. In order <strong>to</strong> achieve this load bearing<br />
elements of structure are required <strong>to</strong> have a demonstrable<br />
standard of fi re resistance.<br />
The degree of fi re resistance for any particular<br />
building depends upon its use, size and location.<br />
Elements of structure are required <strong>to</strong> have specifi c<br />
fi re resistance in order <strong>to</strong>:<br />
➤ Minimise the risk <strong>to</strong> the occupants, some of whom<br />
may not evacuate the building immediately<br />
➤ Reduce the risk <strong>to</strong> fi re fi ghters who may be engaged<br />
in fi re fi ghting or rescue operations<br />
➤ Prevent excessive fi re damage and collapse of the<br />
building<br />
➤ Prevent excessive transfer of heat <strong>to</strong> other buildings<br />
and structures.<br />
