Fire safety guidance strengthened for new high-rise dwellings
07 June 2022
NEW IMPROVEMENTS focused on fire safety guidance and Building Regulations orchestrated to ensure that tall buildings are made safer in England have been introduced by the Government as part of a wider package of reforms.
The changes meet the recommendations outlined in Phase One of the Grenfell Tower Public Inquiry and will strengthen the information available to Fire and Rescue Services.
All new residential buildings over 11 metres in height will now have to include a Secure Information Box that affords Fire and Rescue Services personnel access to important details about a building in the event of a fire.
In tandem, new residential developments over 18 metres tall will also have to incorporate an evacuation alert system that assists Fire and Rescue Services personnel when it comes to informing residents of any change in evacuation strategy during an incident. This affords Fire and Rescue Services an additional tool to use on the ground alongside existing methods of evacuation.
These improvements inform part of a wider update to tighten Building Regulations and provide clearer fire safety rules for the design or construction of residential developments.
Speaking about this news, Fire Safety Minister Lord Greenhalgh asserted: “We have introduced the biggest improvements to building safety in a generation with the passing into law of the Building Safety Act 2022. These changes will support our tough new regulatory regime, duly ensuring that fire safety measures are incorporated into new high-rise homes and also that all new residential buildings meet the same safety standards. It does not end here, though. I urge the industry to act quickly on updating its practises in line with these new rules.”
Response from the NFCC
Gavin Tomlinson, chair of the National Fire Chiefs Council’s (NFCC) Protection and Business Safety Committee, responded: “The NFCC welcomes the introduction of emergency evacuation alert systems in new buildings over 18 metres in height. We also support the inclusion of Secure Information Boxes in buildings over 11 metres, which will give Fire and Rescue Services access to important details about a building and its residents in the event of a fire.”
Focusing on the changes to the Building Regulations, Tomlinson noted: “We are encouraged that unsafe metal composite material polyethylene (MCM PE) core cladding panels are now banned on all buildings and that the Government has promised stronger safety standards for the use of combustible materials on external walls.”
External wall materials
As referenced by Gavin Tomlinson, the Government has indeed introduced tougher standards for external wall materials on new medium-rise blocks of flats.
Previously, the Government announced a ban on the use of combustible materials inside – and on the external walls of – new blocks of flats over 18 metres tall in England, as well as for hospitals, student accommodation and dormitories in boarding schools. Further regulatory updates will now see this ban extended to new hotels, hostels and boarding schools of this height.
Importantly, these changes will ban MCM PE on all new buildings of any height. This follows research carried out by the Government and evidence heard at the Grenfell Tower Public Inquiry on the serious fire safety risks associated with this material.
New statutory guidance will be introduced to restrict the combustibility of materials used in (and on the external walls of) residential buildings between 11 metres and 18 metres in height. This will mean that lower risk developments between 11 metres and 18 metres tall duly meet the necessary safety standards, while allowing designers and developers the flexibility to use environmentally friendly materials.
This builds on a provision – that the Government has already introduced, for sprinkler systems to be installed in new blocks of flats of 11 metres and above in England.
It’s a move that follows on from an extensive consultation and will ensure that residents of all blocks of flats are safe – and, what’s more, feel safe – in their homes.
Other updates to the Building Regulations currently being put forward will:
*include elements of solar shading devices within the scope of the ban
*amend the list of materials exempt from the ban to include fibre optic cables and insulation materials 300 mm from ground level
*update the requirement of the ban to refer to the latest version of the British Standard classification for materials used on high-rise residential buildings
*temporarily exempt cavity trays
*amend the requirements for material change of use in buildings
All of this emerges alongside the Government’s ongoing work to ensure that homebuilders have a clear and comprehensive regulatory framework for the design and development of safe buildings. As part of this, the Government has just published an update on its technical review of Approved Document B and the evidence supporting it.The Government is implementing changes to the Building Regulation’s guidance (ie Approved Document B) in order to meet the Phase One recommendations of the Grenfell Tower Public Inquiry for the provision of Secure Information Boxes and evacuation alert systems.
