the floor area of any upper storey of the building does not exceed200m 2 ; and travel distances conform to those given in the abovetables the house has no more than four floors or, if the house has morethan four floors no upper floor is at a height of more than 11 metres; the stairway conforms with one of the arrangements described in thesection below (“enclosures of stairways”), and in a building more than two floors in height access to the stairwayfrom any room (other than a toilet or bathroom containing no firerisk) is through two sets of fire doors. (i.e. the staircase is protectedby fire resisting lobbies). Where it is impractical to achieve this, inpremises of not more than three floors in height, the lobbyrequirement may be waived subject to a suitable AFD maintenanceagreement, and adequate fire risk management. the house has five or six floors and the arrangements are such as toprovide suitable alternative secondary means of escape.Enclosures of stairwaysIn premises requiring the provision of more than one escape route, themethod whereby a stairway is separated from the remainder of the buildingshould be such as to ensure that a person need not pass through onestairway enclosure to reach the other. If this is not possible the stairwayshould still be separated and it may be reasonable for an alternative route tobypass the stairway by means of balconies or by means of a bypass corridoror, exceptionally, intercommunicating doors between rooms. Bypass corridorsand doors should be of appropriate fire resistance (where necessary) and ofsuitable width (see above). Bypass or intercommunicating doors should bekept free of obstruction and available at all times.Ideally, stairway enclosures should lead direct to a final exit. Where there isonly one stairway for the upper floor(s) of a building and a final exit cannot beprovided from the stairway enclosure, one of the following arrangementsshould be adopted: the provision of two exits from the stairway enclosure, each givingaccess to final exits by way of routes separated from each other byfire-resisting construction; or the provision of a protected route from the stairway enclosure which isdeemed to be an extension of the stairway enclosure leading to a finalexit.Where there is more than one stairway from the upper floor(s) of a buildingand there are no final exits from the stairway enclosures, the stairways andthe routes to their final exit(s) should be separated from each other by fireresistingconstruction and fire doors so that an outbreak of fire at any pointcannot affect more than one escape route from one of the stairwayssimultaneously.London Fire Safety Guidance for Houses in Multiple OccupationVersion 2: 06/06
Glossary of Fire Safety TermsAccess room means a room forming the only escape route from an innerroom.Competent assessor means a person considered suitably qualified,experienced and competent to carry out a fire assessment. Difficult to identifyas no formal qualification. Base identification on relevant experience with theproduct being assessed, track record, reputation, membership of aprofessional association, employment history and relevant qualifications. Willinclude UKAS registered testing houses, reputable fire consultants and themanufacturing company of the product to be assessed.Dead end means a place from which escape is possible in one direction only,or in directions less than 45á apart which are not separated by fire-resistingconstruction.Escape lighting means lighting provided for use when the supply to thenormal lighting fails to ensure that the means of escape can be safely andeffectively used at all material times.Final exit means the termination of an escape route from a building givingdirect access to a place of safety such as a street, passageway, walkway oropen space, and sited to ensure that persons can disperse safely from thevicinity of the building and the effects of fire.Fire door means a door which, if tested in a UKAS registered testing housewould satisfy the following criteria : Assembly to provide 30 or 60 minutes fire resistance (asappropriate) in terms of integrity when tested or assessed to BS 476: Part 22 : 1987. Assembly to provide adequate smoke sealing when tested to BS476 : Part 31.1. Assembly to be installed and maintained in accordance with BS8214 : 1990.Fire assessment report means a considered professional opinion from asuitably qualified person (Competent Assessor) detailing the perceived likelyperformance of a product or construction in a fire situation where theproduct/construction in the assessed condition has not been tested full scale.Issued when a similar product or construction has been tested full scale butthe product/construction to be used varies slightly from the one tested.Assessment reports must always link back to primary test evidence from aUKAS registered testing house. Assessments are required because fire testscover one particular construction of particular dimensions and configurationwhich may vary slightly on-site and it is impracticable to test every possiblesize and configuration.Fire-resisting construction means the ability of a component of a building tosatisfy some or all of the criteria specified in British Standard 476: Part 8 orLondon Fire Safety Guidance for Houses in Multiple OccupationVersion 2: 06/06
