When is fire sprinkler system design not required code#
Code of practice – or BS EN 12845: 2015 + A1: 2019 Fixed firefighting systems. The amended ADB will reduce the height threshold for sprinklers in residential blocks of flats from 30m to 11m, and ‘as a result of the change’ the table reflecting minimum periods of fire resistance ‘will also be amended when these changes take effect to reflect that a block of flats without a sprinkler system above 11 metres is not permitted if following the guidance’ in ADB.Īppendix E will see ‘no changes’, and ‘continue to recommend that sprinkler systems in residential blocks of flats are installed in accordance with the recommendations’ of BS 9251: 2014 Fire sprinkler systems for domestic and residential occupancies. This includes erecting new buildings, material alterations, material changes of use and extensions, with the response focusing on the sprinklers first. In summary, the changes ‘focus on residential blocks of flats and mixed-use buildings containing flats’, with the two main amendments to ‘apply to building works in a block of flats or mixed-use buildings containing flats with a top floor more than 11 metres above ground level’. Its response was sent out in circular letters to council leaders and chief executives, as well as building control heads, approved inspectors and the National Fire Chiefs Council (NFCC), with the government pointing out that hard copies of both volume one (referring to dwellings) and volume two (buildings other than dwellings) would be published later this year ‘when the changes take effect’ on 26 November. This announcement also contained ‘new guidance on consistent wayfinding signage’ for fire and rescue service (FRS) personnel in such buildings. The government announced today the publication of its response to the consultation it undertook on ADB, publishing at the same time an amendment to ADB that ‘extends the provision of sprinklers in blocks of high-rise residential buildings to those buildings with a top floor height of 11 metres above ground level’.
