London Councils welcomes the Assembly's investigation and fully supports any efforts to highlight the importance of fire safety for London's residents and any related remedial action. Since the tragic events of the fire at Lakanal House in July last year our borough partners, both officers and members, have been particularly concerned about fire safety issues. We have explored these .issues at various meetings and will continue to support and lobby on behalf of boroughs in their efforts to ensure the safety of all tenants and leaseholders. At this stage however, we do not have specific data or information that would be of immediate use to the Assembly's investigation, and therefore do not feel that we are able to submit evidence. As you will know we do not own or manage any properties of our own and do not hold the statistical information about the properties owned and managed by London's boroughs needed to answer the first three of the investigation's questions. We will, of course, closely follow the work of the Assembly's investigation and will extend any assistance we can to GLA officials in their work, we look forward to the Assembly's findings and to taking forward its findings and recommendations where possible. FS002 Morgan Professional Services (Morgan Sindall PLC) 1. MPS would estimate an increase in numbers or general trends for timber framed residential buildings, within the next ten years, with respect to cost and sustainability issues. 2. No MPS historical records of the number of fires in either tall or timber framed residential buildings. Would expect these records to be available from insurance companies and local authorities. 3. Would anticipate the London fire brigade or local building control would be aware of new construction or refurbishment on the basis of planning applications, building regulations submittals for approval and fire certification. 4. Relevant regulations would include BS5266, BS5839, BS5306, Building Regulations Approved Documents - Parts L, M & B, the Regulatory Reform Act and Planning Policy Statement 1.BS7974, BS5588-12, BS9251,BS5446,BS5449,BS476, BSEN13501-1, ISBN1-870409-19 5. Responsibility would be allocated at different times of the project. Through the design and planning stage, the responsibility would lie with the design team, i.e. architect, C&S Engineer, M&E Engineer and Fire Engineer. Through the construction period, the construction team would be responsible, including the Clerk of Works. In addition, the fire officer and building control would also be responsible throughout the project. 6. If correctly treated, there is no reason why timber framed buildings should have any additional specific fire risk implications to that of more traditional building methods. 7. MPS would recommend that the timber framing of the building should be treated by impregnation rather than surface treatments. If this is the case there is no reason why timber framed buildings should have any additional specific fire risk implications to that of other materials/building methods. 8. It is our considered opinion that the specific risk associated with tall and timber framed buildings, is that of egress time during a fire condition, i.e. how quickly you can evacuate the building. The issues which can compromise egress post construction are poor maintenance of the automatic detection system, vulnerability of the fire alarm system to vandalism and false alarms caused by lack of commissioning and defective installation. Inherent false alarms will reduce the integrity and confidence respective to the automatic detection system, leading people to consider alarm activation with contempt. 9 Following a consultation process undertaken in 2005 the 200 edition of the Building regulations Part B and the Approved Document B were amended in an attempt to improve fire safety in Dwellings and Non Dwelling buildings. The main areas of change are set out below: Remove provision for self-closing devices in apartments (except doors opening onto common escape routes) and dwellinghouses (except garage doors) Amend the provisions for smoke ventilation of common access areas in apartment buildings Provide for an additional smoke alarm in apartments and dwellinghouses Provide for a suitable system of smoke alarms where an extension is proposed Remove the separate guidance on loft conversions in dwellinghouses Provide for sprinkler protection in high rise apartments and residential care homes Provide for cavity barriers in dwellings and non-dwellings Introduce provisions for measures on inclusive design Amend the provisions for firefighting shafts Provide for dry rising mains in tall buildings Discounting stairs in tall buildings with phased evacuation procedures Design compartment walls to take account of deflections during a fire 10 Would suggest that incidents are reviewed between legislation time periods, i.e. review the incidents after legislation revision and enhancements against the previous legislation, in order to measure effectiveness. MPS do not possess any such statistics and are not aware of any published document. 11 Outstanding actions required to reduce the risk and number of fire incidents would include improved commissioning of automated systems, monitor maintenance standards and the retrofit of new standards within older properties. 12 Additional proposals we feel that should be considered include no ‘battery only’ powered smoke detectors – hard wired only, Sprinklers to be incorporated in all circulation and common areas, Phased evacuation of a floor rather than a single tenancy, on activation of a fire alarm. We also believe that an education campaign should be instigated to educate people of the consequences of good maintenance of alarm/protective systems and to discuss the consequences of vandalism. 13 Educating community action groups via a simplistic Operating and Maintenance manual to inform of procedures and scenarios respective to when the fire alarm system does not work or telephone numbers when vandalism occurs and what to look for in their building to reduce danger, i.e. the obstruction of fire doors or fire doors jammed open, etc. - FS003 Aviva Insurance UK (Via RISCAuthority) In the drive to improve and add to the UK’s housing stock new building techniques are being adopted that also support the sustainability agenda. These build methods are often described under the general heading of ‘Modern Methods of Construction (MMC)’ and include timber frame, structurally insulated panel, and pod techniques. The Fire Protection Association through RISCAuthority (the UK insurer research funding scheme) collate fire loss statistics and investigate fires of special interest. There is now almost universal acceptance by both insurers and Fire & Rescue Services that completed, occupied structural timber framed buildings are not performing well in fires. Ignitions that would normally be contained to their point of origin (e.g. within the consumer unit in an under stairs cupboard) are progressing into the timber voids inherent in the design and are then travelling unchecked to other parts of the building. In our investigations it is clear that Fire & Rescue Services are ill-equipped to address fires in these structures; the usual techniques and equipment not being deployable since they may damage the structural integrity
