EXECUTIVE SUMMARY

Trenton Fire have been appointed by Pick Everard to provide fire safety design services in support of the Kettering Science Table 1 - Summary of fire safety design challenges & departures from guidance Academy in Kettering. Design item Challenge Proposal Reference This fire safety strategy has been developed to satisfy the requirements for fire safety under the Building Regulations 2010 (including amendments). This has been achieved through compliance with the recommendations for life safety of B1 Escape within 4.5m of A secondary means of escape will be provided from those 4.8.2 “BS 9999:2017 – Fire safety in the design, management and use of buildings – Code of practice” (BS 9999) in the first a void edge classrooms, which will enable occupants to avoid having to instance. In line with the objectives set by the client, the strategy has not been developed to include any additional specific travel within 4.5m of a void edge. measures for the protection of property. However, features that are included for life safety will contribute in some extent to property protection and business continuity. B4 Non-compliant In order to reduce the risk to life safety posed by fire 5.3.3 and notional boundaries spread in between the existing and proposed school 5.3.4 Apart from where noted in this report, the designs will be in accordance with the recommendations of BS 9999. To facilitate imposed by site buildings on the same larger site, it is proposed to operate ease of review by the building control body, the items departing from BS 9999 are identified in Table 1, along with the condition both as a single building, supported by an interlinked fire respective proposed alternative fire engineering solutions. All aspects of the fire safety design will be subject to review by detection and alarm system and emergency voice the building control body and the local fire and rescue service, and ultimately formal approval by the building control body. communication system. Additionally, enhanced provisions The school is a rectangular three-storey building (G+2) serving secondary school students. The building will have a footprint for the fire and rescue service are proposed. of approximately 960m2 and a combined floor area of circa 2,880m2. The building will have a typical storey height of approximately 3.6m, with the finished floor level of the topmost floor level (2nd floor) located approximately 7.2m above fire and rescue service access level (ground floor). The school is intended to accommodate a total of 722 pupils and members of staff. The site to be developed will be part of the larger school site and in very close proximity to the main school building. Access to the above-ground storeys will be provided via three stairs. Community access will be provided out-of-hours only to the ground floor of the building. Trenton Fire understand that the provision of a property protection sprinkler system is not a requirement of the project stakeholders. The fire safety provisions contained within the strategy will be sufficient in order to meet the life-safety requirements of the Building Regulations without the inclusion of a life-safety sprinkler system, and as such, a sprinkler system will not be provided. A simultaneous building evacuation regime will be utilised for the new building which will be connected to the existing building, with a single-stage alarm protocol, i.e. evacuation of both buildings upon automatic detection or operation of a manual call point anywhere in either building. In support of the evacuation regime, the fire detection and alarm systems and the emergency voice communication systems will be interlinked in between the existing and new buildings in order for both to be operated as a single larger building. Evacuation from the above-ground floors will be via the two lobby protected escape stairs. Disabled occupants will be assisted in their evacuation where required, and will be provided with suitable refuge areas. Ground floor occupants will be able to escape via final exits leading directly to the outside. The school will be constructed as a single fire compartment. Fire-resisting construction is utilised in support of the means of escape arrangements, including cross-corridor separations and protection to dead-end areas. Ancillary areas having a heightened fire risk (e.g. changing rooms, store rooms, kitchen, plant rooms, server rooms, lifts) will be enclosed by 30- minute or 60-minute fire-resisting construction. Firefighting access and facilities in the building will be provided in excess of minimum code compliance recommendations. It is proposed to provide firefighting access to 25% of the building perimeter, with primary access provided via external doors into the northern lobby-protected stair that will also include a dry rising fire main. Hose coverage will be achieved for all areas of the building within 45m from a dry riser outlet. The water supplies for firefighting operations will be provided via either existing or new hydrants.

2.2 Design occupancy Table 3 – Design occupancies 2.2.1 This strategy is based on occupancy levels determined using floor space factors for each area, as set out in Table 9 Floor Area Occupancy Risk Profile of BS 9999, input from the design team, as well as Trenton Fire’s design experience with schools. The calculated design occupancies noted in Table 3 will be utilised when determining the required capacity of the means of escape Lecture Theatre 56 A2 routes. Second General Classroom (6 No.) 28 A2 2.2.2 The strategy assumes that where out-of-hours or public events are to be held within the school on the ground floor, the maximum occupancies will not exceed those stated within Table 3, unless subject to a suitable fire risk Small Group Room 4 A2 assessment for the proposed use and mitigated accordingly. Total for second floor 228 A2 2.3 Occupancy risk profile 2.3.1 BS 9999 recommends fire safety provisions such as warning systems, means of escape and compartment sizes, First General Classroom (6 No.) 28 A2 based on assumed risk. This is achieved by allocating a risk profile based on occupancy (e.g. A – awake and familiar, or B – awake but unfamiliar) and the likely fire growth rate (e.g. 2 – medium growth rate, or 3 – fast growth rate). ICT Classroom (2 No.) 28 A2 2.3.2 BS 9999 does not describe in detail what constitutes the characteristics of risk profiles “A” or “B”. However, the Deputy Office 3 A2 following occupant characteristics will be applied: Total for first floor 227 A2  Any group utilising the building with regularity (e.g. students and staff) are occupant characteristic “A”; Ground Common / Dining Room (community use) 160 B2  Small groups (e.g. visitors and parents) that are accompanied at all times by trained staff are acceptable in a building of occupancy characteristic “A”. Staff should provide a fire safety / evacuation induction; and Library 20 B3

 Groups utilising the building infrequently (i.e. community use), are considered as occupant characteristic “B”. ICT Resource 15 B3 2.3.3 In support of out-of-hours or community use, ground floor areas (except staff areas) will conservatively be assumed Study Area 40 B3 to employ a B occupancy characteristic, assuming occupants are not familiar with the building. All areas on the first and second floor as well as staff only areas on the ground floor level will employ an A type occupancy characteristic, Small Group Room (2 No.) 4 B2 assuming occupants herein are familiar with the premises. Deputy Office 3 B2 2.3.4 For standard risk areas, a base fire growth rate of “Medium” (2) will be applied, while for areas deemed to have a greater fire growth rate, a base fire growth rate of “Fast” (3) will be applied. Conference Room 12 B2

2.3.5 Certain areas will be enclosed within construction having a fire-resistance rating of 30 minutes or better, thereby Interview Room 3 B2 protecting the occupants of other rooms on that storey. Accordingly: Staff Work Prep 10 B2  The building will generally be assigned a medium fire growth rate, with an fast fire growth rate being applied to higher fire hazard rooms, which will be enclosed in fire-resisting construction; and Total for ground floor 267 B2  Areas used outside of school hours will be assigned a B occupancy characteristic. Rooms having a fire hazard Total for building 722 B2 rating (i.e. plant, kitchens, science labs) will not be occupied by unfamiliar occupants unless subject to a suitable fire risk assessment. Notes: 2.3.6 All plant, kitchen, cleaner and store areas will employ a fast fire growth rate. All other areas will employ a medium Transient areas have not been considered with respect to total building occupancy in order to avoid double fire growth rate. No reduction in the fire growth rate is proposed at this stage as an automatic water fire counting occupants. suppression system will not be provided. Transient areas include the following areas: Class Resource (Store), Plant Room, Cleaner Store, Central Resources (Stores), ICT Hub, Equipment Store, Premises Store, Furniture Store, Kitchen Servery, Kitchen 2.3.7 As the ground floor community use areas are connected through the void towards the above floors, the B2 risk Cleaner, Tank Room, Plant Room, etc. profile has been conservatively adopted for sizing the vertical means of escape. All the aforementioned transient areas include a A3 risk profile. 2.3.8 Risk profiles for each area of the building are summarised in Table 3 and are applied throughout the remaining sections of this report. Individual rooms with a high growth rate are separated from the remainder of the storey / compartment by fire rated construction, thus allowing for the more onerous risk profile to be assigned to the individual room in isolation while the wider storey was assigned a medium fire growth rate.

3. MEANS OF WARNING AND ESCAPE

The Building Regulations requirement B1 states: 3.3.2 BS 9999 recommends escape widths, escape distances and stair widths based on the risk profile and the minimum fire protection measures. The BS 9999 recommendations for travel distance and horizontal escape width have been “The building shall be designed and constructed so that there are appropriate provisions for the early warning of extracted as presented in Table 4. fire, and appropriate means of escape in case of fire from the building to a place of safety outside the building capable of being safely and effectively used at all material times.” 3.1 Evacuation Regime Table 4 –Escape width and travel distance limitations 3.1.1 A simultaneous building evacuation regime will be utilised for the new building which will be connected to the Risk profile A2 A3 B2 B3 Roof level existing building, with a single-stage alarm protocol, i.e. evacuation of both buildings upon automatic detection or operation of a manual call point anywhere in either building.

That is, the travel design certificate for the scheme to the Approving Authority prior to commencement of the installation on site. distances, exit numbers and widths meet the recommendations of BS 9999 (as shown in Table 4) for the risk profiles and likely occupancy. General consideration will need to be given to the layout of equipment and furniture within 3.3 Means of escape provisions rooms to ensure that actual travel distances remain within these stated limits. 3.3.1 The general philosophy for means of escape is that the occupants of a building should be able to turn their back 3.4.2 A number of areas that are accessed via the circulation corridors are to be considered as inner rooms, as the on a fire and escape via the nearest exit without additional assistance from other occupants or firefighters.

16.3.4 of BS 9999 without requiring additional measures specifically to address this issue. All inner rooms will have and smoke shutter (see Section 4.8.2), to start close immediately upon activation of the fire alarm. This shutter occupancies not exceeding 60 persons, and will not be accessible via rooms of special fire hazard. should also be provided with an emergency fireman’s override switch. 3.4.3 All doors should have a minimum clear effective width of 800 mm, or 850 mm where unassisted wheelchair access 3.5.4 Handrails which do no protrude more than 100 mm into the clear stair width may be disregarded as impacting is required, unless specifically identified below or on the accompanying fire mark-ups. However, BB 77 [10] upon the recommended stair width. (replaced by BB 102 [11]), BB 99 [12], Approved Document M (ADM), Approved Document K (ADK) [13], and the Standard Specifications Layouts and Dimensions (SSLD) for School Buildings booklets may require additional width. 3.5.5 The ground floor final exits are considered to provide sufficient capacity for ground floor occupants to evacuate It is recommended that the doors leading into a disabled refuge location are wide enough to accommodate without significant numbers of occupants having to evacuate via the base of the stairs (approx. 60 occupants as a unassisted wheelchair access. maximum). Therefore, it is considered that merging flow scenarios need not be applied when determining the final exit widths from the protected stairs. 3.4.4 Where corridors greater than 12 m in length connect storey or final exits, these are sub-divided by FD30S cross- corridor doors. These are provided throughout the building. 3.5.6 The final exits from the stairs at ground level will each provide a clear width of 1,600mm which is in excess of the widths of the approaching stairs. 3.4.5 To assist with day-to-day circulation, any cross-corridor doors will be provided with magnetic door hold-opens, as detailed in Section 3.9. The cross-corridor doors should provide a clear width of at least 1,050 mm, and be dual- 3.6 Roof escape provisions swing doors, in order to accommodate over 60 occupants in either direction of escape. These doors should be 3.6.1 Roof access and egress will be provided via a hatch. The current design includes a hatch leading into the plantroom released at night time to reduce the chance of long term warping of the door as it is held back at a single point of on the second floor which is not permitted, therefore this should be relocated to discharge within the northern contact. protected stair enclosure. The hatch and any roof level walkways will be arranged such that travel distances do not exceed 45m in a single direction. 3.4.6 All dead-end corridors greater than 2 m in length will be provided with 30-minutes fire-resisting construction and any doors opening into them should be protected by FD30S door sets. Low hazard ancillary accommodation areas 3.6.2 All maintenance staff accessing the roof areas should be able to evacuate via escape hatches unaided of the routes (e.g. stores) which open into a dead-end corridor will be provided with FD30S doors. Dead-ends will serve small described in this section unaided, and should be fully briefed with regards to the emergency evacuation procedures numbers of occupants, and not more than 60 people.

Fume cupboards should be located as 3.7.1 Travel beyond the building final exits must be away from the building, towards a place of safety, and not be far as reasonably practicable from the room exits. jeopardised by unprotected openings of the building. It is proposed that this is achieved through a combination of the following: 3.4.8 The ground floor main dining / common room has a maximum design occupancy of 160 people. Two 1,800mm wide exits leading outside are provided, allowing sufficient egress capacity for 300 occupants per exit (B2 risk  Alternative paths along the building that cannot be impacted by a single fire location; profile). Two additional exits (850mm wide each) providing a combined capacity of 166 people are also provided  Exit paths provided that lead away from the building. via the Library / ICT / Study areas which should be available even in the case of a major fire within the neighbouring existing school building. 3.7.2 Final exits should not present an obstacle to wheelchair users and other people with disabilities.

These escape routes should be suitable for the use of a provide sufficient capacity for all occupants on that level. disabled occupant. This is likely to impact on landscaping design. 3.5 Vertical evacuation 3.7.4 In order to avoid having protected façade as a consequence of maintaining disabled escape routes, the entire perimeter of the building should include a 2m wide accessible route. This would result in the disabled occupant 3.5.1 The two protected stairs will each have a minimum clear width of 1,300 mm, providing a total vertical egress having a choice of two direction of escape on this level, once outside the building. capacity of 650, which is considered sufficient to accommodate the maximum design occupancy for the above ground level of the school (455). 3.7.5 The determination of suitable assembly areas is an operator-led exercise.

A Generic 3.10.1 Emergency lighting will be installed to provide temporary illumination in the event of failure of the primary power Emergency Evacuation Plan (GEEP) will need to be written for members of the public who would need assistance supplies to the normal lighting system. As part of the emergency lighting system, escape lighting will be provided to escape. These plans should not rely on assistance from the fire and rescue service and should the plans include to ensure the escape routes are illuminated at all material times. Adequate artificial lighting will be provided in all hardware such as descent aides, consideration for location/storage can be incorporated into the design at this escape routes and will be of a sufficient standard to enable persons to see during escape. stage. Further information can be found in BS 8300 and the DCLG Publication “Fire Safety Risk Assessment Supplementary Guide – Means of Escape for Disabled People”. 3.10.2 Emergency lighting will be installed in accordance with the recommendations of BS 5266: Parts 1-2 [22] and 4-6, BS EN 1838 [23], and BS EN 60598-2-22 [24]. 3.9 Fire doors and escape doors 3.9.1 All fire doors should be provided in accordance with Clause 32.1 of BS 9999. 3.10.3 Emergency lighting will illuminate all occupied areas, common evacuation routes (internal and external as necessary) and essential areas including plant areas (external plant also). It will also illuminate a safe exit route 3.9.2 All doors on common escape routes will either not be provided with a securing device, or be provided with a including fire exits, fire alarm call points, changes in level or direction and fire-fighting equipment. Lighting to securing device that is easily openable from the inside without the use of a key and without having to manipulate escape stairs should be on a separate circuit from that supplying any other part of the escape route. more than one mechanism. Doors should open in the direction of escape where possible. 3.10.4 Primary and emergency lighting will be required for any external escape routes that will not be lit by surrounding 3.9.3 Doors on escape routes will generally be hung to open in the direction of exit (apart from certain instances where street lighting. the doors will serve less than 60 people), will open not less than 90° and have a swing which is clear of any change in level, other than a threshold or single step on the line of a doorway. 3.10.5 Where used, it must be ensured that the emergency lighting will provide at least the minimum level of illumination to photo-luminescent escape signage (Clause 5.3 of BS 5499-4 [25] - a minimum of 100 lux on the vertical and in 3.9.4 The clear widths of exit doors should, as a minimum, meet the recommendations of Table 4 and Section 3.4. the event of mains failure conditions a minimum of 5 lux in the vertical, with a uniformity of 0.7). 3.9.5 Doors opening onto stairways or corridors will be sited so as not to encroach on the effective width of any stairway, 3.10.6 Emergency lighting will illuminate common areas and the exit routes including fire exits, changes in level or landing or corridor. direction and firefighting equipment. Lighting to escape stairs should be on a separate circuit from that supplying 3.9.6 Vision panels will be provided in any doors that swing in both directions and in doors sub-dividing corridors on any other part of the escape route. escape routes. Other vision panels may be required as part of accessibility requirements.

3.10.7 A facility should be provided for periodic testing of the emergency lighting luminaires without having to switch the relevant circuit off. A full discharge / recharge test must be performed for every luminaire during commissioning procedures. 3.10.8 Discharge lighting installations may operate at voltages that are a hazard to firefighters. An exterior discharge lighting installation, or an interior discharge lighting installation operating unattended, operating at a voltage exceeding low voltage (as defined in Statutory Instrument number 1018, part of the Building Regulations), should be controlled by a firefighter’s emergency switch, installed and situated in accordance with BS 7671 [26] and the requirements of the fire authority. 3.11 Fire safety signage 3.11.1 Fire safety signs will be installed in common areas where necessary to provide clear identification of fire precautions, fire equipment and means of escape in the event of fire. All parts of the building will be fitted with appropriate fire safety signage to comply with The Health and Safety (Signs and Signals) Regulations 1996, i.e. signage to be in accordance with BS ISO 3864-1 [27], BS 5499-4 [28], BS 5499-10 [29] and the Safety Signs and Signals: Guidance on Regulations publication [30]. 3.11.2 The purpose of fire signage is to direct persons towards fire exits, or to provide specific information or warning about equipment, doors, rooms or procedures. They should be recognisable, readable and informative, as they convey essential information to regular and infrequent users of the premises, and the Fire and Rescue Service (FRS). 3.11.3 Fire notices should be permanently displayed in conspicuous positions throughout the building, including storey exits, and should have been updated to provide information specific to building. 3.11.4 All fire doors will be marked with the appropriate fire safety sign conforming to BS 5499-1 [31] (white on blue) according to whether the door is:  To be kept closed when not in use (‘FIRE DOOR - KEEP SHUT’);

 To be kept locked when not in use (‘FIRE DOOR - KEEP LOCKED’); or  Held open by an automatic release mechanism (‘AUTOMATIC FIRE DOOR - KEEP CLEAR’). 3.11.5 Fire doors to cupboards and to service ducts should be marked on the outside at about eye level. All other fire doors should be marked on both sides at approximately eye level. 3.11.6 Any emergency securing device fitted to doors on escape routes are to be provided with instruction notices, adjacent to the device, indicating the method of operation. 3.12 Out-of-hours school use 3.12.1 It is expected that many areas within the building will be utilised outside of school hours, or for community use, including the dining / common room, along with adjacent areas at ground floor. The means of escape from the building provide suitable escape width to allow community use. 3.12.2 It should be ensured that where members of the public are allowed access to other areas of the school, they will be accompanied at all times by a member of school staff. 3.12.3 In the event of an out-of-hours fire, the magnetic locking systems installed on exits located within the secure line should deactivate upon detection, allowing occupants to use the same egress routes that would be available during school hours use. These arrangements should be incorporated into the fire-safety management plan for the building, when developed (see Section 7.5.6). 3.12.4 The means of escape for ground floor areas with both community use and school use have been designed based on the more onerous B2/B3 risk profile, such that these exits are able to accommodate both use types, provided that the maximum occupancies in Table 3 are followed.

For the purposes of this sub paragraph a house in a terrace and a semi- corridors should be treated as inner rooms (see Section 3.4.2). Also, lockers are not permitted within stairs or detached house are each to be treated as a separate building. lobbies providing protection to escape stairs. (3) Where reasonably necessary to inhibit the spread of fire within the building, measures shall be taken, to an extent appropriate to the size and intended use of the building, comprising either or both of the following: 4.3 Displays on teaching room walls 4.3.1 In classrooms, notice boards with a surface spread of flame no poorer than Class 3 or D-s3, d2 are permitted, but (a) sub-division of the building with fire resisting construction; should not extend more than 2.5 m without having a break between them of not less than 0.4 m. (b) installation of suitable automatic fire suppression systems. 4.4 Fire suppression (4) The building shall be designed and constructed so that the unseen spread of fire and smoke within concealed 4.4.1 A fire suppression system is not required to comply with the recommendations of BS 9999 and will not be provided spaces in its structure and fabric is inhibited.” in the building. The fire safety strategy is designed such that the building meets the functional requirements of 4.1 Internal Linings Parts B1-B5 of the Building Regulations without the provision of a life-safety sprinkler system. 4.1.1 In the early stages of a fire in a building, the choice of material for the lining of walls and ceilings can significantly 4.4.2 Within the kitchen, considerations should be given to providing a proprietary extinguishing system, should cooking affect the spread of fire and its rate of growth. Wall and ceiling linings should achieve at the surface spread of flame facilities be employed within this area at any time. If applicable, proprietary extinguishing systems covering hob and fire classifications outlined in Table 33 of BS 9999, as summarised in Table 5, as a minimum. Materials are top and the cooker hoods should be considered. This will be of benefit to both life safety and the minimisation of permitted to meet either the UK National or the European classifications noted. fire damage. 4.1.2 Parts of the wall area of an individual room are permitted to be of a poorer performance classification than those 4.5 Structural fire resistance set out in Table 5, but no worse than UK National Class 3 or European Class D-s3, d2. This variation is limited to an 4.5.1 As the building will have top storey height above access level of approximately 7.2 m, elements of structure should area not exceeding half the floor area of the room or 60 m2, whichever is less. achieve a fire resistance of at least 60 minutes, as specified in Table 23 of BS 9999. 4.1.3 Should any thermoplastic materials, which do not achieve the performance given in Table 5, proposed in the 4.5.2 Elements of structure that only support a roof do not generally require fire resistance. Structure is considered to construction (e.g. windows, roof-lights and lighting diffusers only) these should comply with the recommendations support more than only a roof if it supports a load other than the roof itself (e.g. rooftop plant) or is essential to of Section 34 of BS 9999. the stability of a compartment or other fire-resisting wall (internal or external). Photovoltaic (PV) cells on the roof Table 5 – Surface spread of flame requirements are not considered to constitute plant in this context. Location National (UK) Class European Class 4.6 Compartmentation and fire-resisting construction 4.6.1 Performance requirements for fire resisting separations are documented in Table 6. The fire safety mark-ups Small rooms ≤ 30 m² Class 3 D-s3, d2 presented in Appendix A denote the minimum fire-resistance requirements for various fire separating elements Other rooms Class 1 C-s3, d2 and enclosures. The identification of the structural, secondary structure, and load bearing elements should be sought from the structural consultant and the appropriate fire-resistance noted in Table 6 should be applied. Circulation spaces Class 0 B-s3, d2 4.6.2 Table 28 of BS 9999 imposes a limit of 2,000 m2 for the maximum area of any floor in a building with an uppermost storey of less than 18 m and a B3 risk profile, which is the most onerous in this case. This limit is not exceeded for this building, therefore the entire building will be enclosed in a single fire compartment.

4.6.3 As part of the design provisions in support of means of escape and fire-fighting operations, the north and south of the cupboards, the restrictive safe zones and positioning limitations in relation to room circulation paths and stairs will be designed as lobby protected stairs, to be enclosed in 30-minute fire resisting construction including escape routes, the substances and processes used, and the risks associated with fume cupboard accidents or lobby separation achieving 30-minute fire resistance rating on all levels. extraction system failures, rooms containing fume cupboards will be designated as low-hazard ancillary rooms. Table 6 – Minimum fire resistance periods for structural and-separating elements (in minutes) 4.7.2 As previously noted, all rooms and spaces (risers) that have the potential for a fast fire growth rate will be designated as places of higher fire hazard and will be enclosed within fire-resisting construction to isolate their risk. Elements requiring fire-separation Fire resistance Exposure Fire doors 4.7.3 Accordingly, the following areas have been designated as low hazard ancillary rooms and/or places of higher fire Structural frame, beam or column 60 L Exposed faces N/A hazard: stores of any kind, kitchen, changing rooms, ICT hub, server, class resource, prep areas, any room with a fume cupboard, and all service risers. Protected stair lobbies 30 L/Int/Ins From each side FD30S 4.7.4 All plant rooms have been designated as high-hazard ancillary accommodation. Subdivision of a corridor 30 L/Int/Ins From each side FD30S 4.7.5 If applicable, any areas fitted with gas supplies should follow the advice given in Gas Engineers publication “UP11 Gas installations for educational establishments”. Each such area should be fitted with a lockable isolating valve to Protection of dead-end corridors 30 L/Int/Ins From each side FD30S enable gas supplies to gas taps on benches to be shut off at the end of the day. Where fume cupboards are provided Protected lift and service shafts 30 L/Ins/Int From each side FD30 these should have a powered extract system and fire resisting ductwork to extract hot smoke in case a fire occurs within them. Low hazard ancillary accommodation (as per Table 29 of BS 9999) – e.g. stores, PE stores, 30 L/Ins/Int From each side FD30 4.8 Automatic fire barriers kitchen, labs, low-voltage electrical rooms 4.8.1 The kitchen area will not include food preparation and therefore is not considered as high risk. However, in order to enable flexibility in use in the future, it is recommended to include fire separation around the potentially high Higher hazard ancillary accommodation (as per risk food preparation area. Therefore, any openings between the kitchen and the dining hall which are intended Table 29 of BS 9999) – e.g. plant rooms, 60 L/Ins/Int From each side FD60 for servery use should be provided with fire shutters, rated to 60 minutes fire resistance rating (integrity only). electrical intake rooms There is not expected to be any fire load close-up to the opening as it is used as transient space in typical use so Notes: fire spread through the shutter via radiation is unlikely. Therefore, integrity-only is considered to be sufficient for the fire shutters. In the event of a fire within the kitchen, the shutters should descend and restrict the spread of Loadbearing, Integrity, Insulation in accordance with BS 476 parts 21 [54] & 22 [55]. The “L” rating only applies fire, thus maintaining the fire resisting separation of the kitchen. to loadbearing elements. “S” within the fire doors column denotes the inclusion of cold smoke seals on the fire doors. 4.8.2 Additional local FR30 construction has been proposed to enable occupants to avoid escape within 4.5m of the void edge as presented on the mark-ups, in Appendix A. The lift shaft opens into the base of the void and also into the Fire doors for ancillary accommodation and riser shafts also require cold smoke seals if located if they open into corridor which forms a secondary means of escape for occupants having to escape within 4.5m of the void edge. a dead-end corridor (see Section 3.4.6), protected escape route and are located on a compartment line or line of cross-corridor separation as shown by the mark-ups in Appendix A. In order to mitigate this condition, an FR30 minutes (integrity only) fire and smoke shutter is proposed within the lift aperture on the ground floor level.

4.6.4 As floors are not required to be compartment floors these may contain floor voids. One key architectural feature 4.8.3 Automatic shutter barriers should be tested or classified in accordance with BS 476-22 or BS EN 13501-2 [34]. in this building is the central void spanning all floors which includes the western accommodation stair. However, 4.8.4 The 30-minute fire and smoke curtains will be specified in accordance with BS 8524-1 [29] and designed, installed solid areas of floor will otherwise be fire-resisting to meet the standard documented in Table 6 for supporting and maintained in accordance with BS 8524-2 [30]. Detailed performance criteria will be confirmed as the design means of escape from the upper floors. Sealing of penetrations within these floors is not required unless the floor progresses. forms part of a protected escape route. 4.9 Robust construction 4.6.5 In order to provide a protected lobby for the northern and southern stairs, 30-minute fire resisting construction 4.9.1 By the nature of the activities that go on within a school, the elements of construction making up the school should including integrity and insulation should be provided. At the moment, the design includes glazing in such partitions be able to withstand more abuse than those incorporated in the normal built environment. Accordingly: which should be also fire rated to achieve the same performance.  All glass should meet the requirements of BS 6262-4 [35], BS 6180 [36] (if used in a barrier), and BS 5234 (if 4.6.6 It is proposed to enclose and isolate areas of increased fire growth rate with a minimum of FR30 minutes rating used in a partition; construction thereby protecting the escape routes and other areas on that level from the higher risk.

 Door hardware will be essential or non-essential depending on door function and fittings, as per BS 8214 [42]. 4.11.4 Cavity barriers should be within the external wall cavity, positioned to align with the internal fire-resisting walls and floors, unless constructed in accordance with Figure 36 of BS 9999. Cavity barriers should also be installed to seal 4.10 Fire-stopping and penetrations through fire-resisting construction around any openings (windows or doors) in the external wall. Cavity barriers provided around an opening may be 4.10.1 Fire-stopping should be provided at the junction of fire-separating walls and external walls to maintain the fire formed of: resistance period of fire-separating walls (see Figure 4), and thereby prevent a fire from travelling around the junction and into the neighbouring space.  Steel at least 0.5mm thick or timber at least 38mm thick; 4.10.2 To maintain the fire resistance of separating construction, any pipe penetrations through lines of fire-resisting  Polythene-sleeved mineral wool, or mineral wool slab under compression when installed cavity; or separation should be fire-stopped in accordance with one of the following methods set out by Clause 32.5.14 of  Calcium silicate, cement-based or gypsum-based boards at least 12mm thick. BS 9999, unless located within a protected shaft:

 For pipes of any diameter, a proprietary seal, which has been shown by test to meet the fire-resistance rating of the wall, floor, or cavity barrier for the penetration circumstance; and

 For pipes with a restricted diameter, fire-stopping should be provided around the pipe keeping the opening as small as possible. The nominal interior diameter of the pipe should not be more than the relevant dimensions given in Table 31 of BS 9999. Figure 4 is provided to assist in the interpretation of Table 31 of BS 9999. 4.10.3 All pipes, ductwork and services passing through fire-resisting separations should be either enclosed in fire- resisting construction (i.e. shafts) of matching fire resistance or provided with fire dampers of matching fire resistance. Certain small-diameter pipes require only fire-stopping around the pipe, dependent on pipe material and the type of fire-resisting barrier penetrated. 4.10.4 Where ducts cross fire-resisting construction enclosing a protected escape route (e.g. protected stair, protected corridor, protected lobby or a corridor sub-division), fire dampers on fusible links are not sufficient. Either combined fire-and-smoke dampers activated upon smoke detection (ES-type dampers) are provided, or the duct should be fire-resisting/enclosed within fire-resisting construction throughout its length while traversing the protected escape route. As such, all ductwork penetrating the protected stair enclosures, fire separation lines and protected lobbies / corridors should be provided with ES-type dampers. 4.10.5 Dampers should not be used if the duct used for extract is serving a kitchen area. Such ductwork should be fire- resisting or fully within a fire-resisting enclosure to the point of termination outside of the kitchen enclosure. Additional guidance is provided in BESA TR19 “Guide to good practice – Internal cleanliness of ventilation systems”. 4.11 Concealed Spaces

4.11.1 Cavity barriers are provided to prevent the rapid spread of unseen fire or smoke in voids, and to prevent the spread Figure 4 – Fire stopping expectations of fire around compartmentation via voids.

4.11.2 Concealed cavities (e.g. voids in partition walls, roof voids, void between suspended ceilings and the soffit of the floor above) require cavity barriers to sub-divide them, unless subject to the exceptions outlined in Clause 33.2 Items (a) to (g) of BS 9999. 4.11.3 Cavity barriers should achieve 30 minutes integrity (E) fire resistance and 15 minutes insulation (I) fire resistance. They should be located as follows:

 In general, cavity barriers should be at 20 m centres in cavities with exclusively Class 0 or 1 linings. For other linings, the spacing between cavity barriers should be reduced to 10 m; and

 Above walls enclosing protected escape routes, where the wall does not continue to the level of the soffit or roof above.

5. EXTERNAL FIRE SPREAD

The Building Regulations requirement B4 states: 5.3.6 It is critical that school management including any prospective insurers are made aware of the fact that fire spread in between the two buildings is possible from a property protection / business continuity / insurance point of view. “(1) The external walls of the building shall adequately resist the spread of fire over the walls and from one building to another, having regard to the height, use and position of the building. Should any party not agree with the potential loss of both buildings in a fire scenario, then options could be investigated to mitigate fire spread, however this are likely to be highly onerous. (2) The roof of the building shall adequately resist the spread of fire over the roof and from one building to another, having regard to the use and position of the building.” 5.3.7 The design team are to confirm the actual boundary distances towards the east (site boundary) and north (middle of the adjoining road) in order finalise the analysis and estimate the required mitigation on those facades. 5.1 External surfaces of walls 5.1.1 Façade linings should conform to Clause 35.5 and Figure 47 of BS 9999. Table 7 – Limitations on roof coverings 5.1.2 As the building includes areas of out-of-hours community use, with a risk profile of B2/B3, is less than 18 m in Designation of roof covering height and more than 1 m from all boundaries, façade linings for the fire compartment containing these areas Distance from relevant should comply with the requirements in Figure 47c) of BS 9999. boundary AA, AB, or AC -National BA, BB, or BC – National CA, CB or CC – National 5.1.3 BS 9999 recommends that façade linings up to 10 m above ground level and up to 10 m above a roof or parts of BROOF(t4) - European CROOF(t4) - European DROOF(t4) - European the building to which the public have access should achieve Class 0 (national class) or Class B-s3, d2 or better Less than 6m    (European class).

Where any plastic or thermoplastic materials are used At least 20m    for rooflights, these are to conform to the provisions of BS 9999. Recommendations given in this table are not exhaustive as dispensations are provided in BS 9999, including for 5.3 Space separation and unprotected façade areas rooflights. 5.3.1 In order to investigate the risk of fire spread to / from neighbouring properties / buildings via radiation, analysis Table 8 - Boundary distance requirements for 100% unprotected façade has been undertaken in accordance with the calculation process outlined in BR 187 [44], to determine the boundary distance separation required for 0% unprotected façade. The results are presented in Table 8. Elevation Height Width Radiation Boundary distance Actual boundary intensity for 100% distance 5.3.2 It can be observed that for this site, fire spread is possible towards the existing building across the notional (m) (m) unprotected façade boundaries. These notional boundaries have been introduced retrospectively on the larger school site, after the (kW/m²) (m) existing main school building had been already built. As a consequence, the new site boundaries represent notional (m) boundaries in accordance with Section 35.1.2 of BS 9999. Trenton Fire have not received any information up to this point to indicate that the proposed building extension on the same site was taken into consideration by the South 11.5 30 84 11.9 3 design team for the existing building. Therefore, it is also possible that a fire scenario within the existing main West 11.5 30.9 84 12.1 3 building to result in fire spread towards the new proposed building. North 11.5 30 84 11.9 TBC 5.3.3 In order to mitigate this condition with respect to life safety of occupants, the fire detection and alarm systems should be interlinked and include a robust, wired connection so that detection anywhere within the two buildings East 11.5 30.9 84 12.1 TBC results in an immediate alarm in both buildings. Furthermore, the disabled refuge EVC systems and supporting management procedures should be interconnected to cover both buildings at the same time. Overall, the two Notes: buildings will end up being operated as a single larger building. Further detail is presented in Section 3. The radiation intensity of 84 kW/m² has been selected for the entire façade radiator which is the governing 5.3.4 In order to mitigate this condition with respect to life safety of firefighters, the local fire and rescue service should value for most of the areas. Even if some rooms could locally employ 168 kW/m², these are limited in size and separated by FR construction from the rest of the building. This is considered conservative as the entire be consulted with respect to this departure to ensure that they are satisfied with the design overall, taking into façade is not likely to be engulfed in a full compartment fire. Furthermore, the combustibles within the account that the building incorporates 6m separation from the existing building and also incorporates higher risk areas are more akin to school / office accommodation. enhancements with respect to provisions for firefighting as presented in Section 6. The actual boundary distance towards the south and west have been confirmed by the design team as 5.3.5 However, Trenton Fire recommend that fire rated façade system be employed towards the south and the west in measured up to the notional boundary halfway towards the existing building. order to prevent fire spread. A detailed analysis on the actual required mitigation can be performed at a later stage The actual boundary distance towards the east and north have to be confirmed by the design team in order to in coordination with the design team. finalise the analysis and inform on the mitigation required on the associated elevations.

8. DESIGNER’S ASSESSMENT FOR FIRE SAFETY DURING CONSTRUCTION

8.1 Introduction 8.1.1 The Construction (Design and Management) Regulations 2015 (CDM 2015) [1] sets out what designers are required to consider to protect those involved in the construction or ongoing use of a project. As part of this legislation, designers are required to provide consideration of specific challenges presented by their design, and to remove, reduce or consider how risk would be suitably managed, whilst this can influence the design of the building. 8.1.2 The Fire Protection Association (JCOP [2]) and the Health and Safety Executive (HSE) (HSG168 [3]) issue guidance on identifying and managing fire precautions during construction works, which should be consulted by the principle contractor or their specialist advisor when developing their construction fire safety plan. This guidance is also utilised within this designer’s risk assessment. 8.1.3 Ultimately, the provision of a suitable degree of fire safety within the construction site will be the responsibility of the principle contractor, supported by their fire safety specialist (where appointed). This section provides initial consideration of solutions which may provide a suitable degree of fire safety during construction within the constraints of the permanent design. 8.1.4 This section is not intended to be exhaustive or to provide comprehensive solutions. The intention of this section is to outline possible fire safety solutions to demonstrate that an adequate level of fire safety during construction is viable, and how this may be achieved. The principle contractor may utilise and develop the following proposals, or implement alternative solutions where considered preferable and providing a suitable degree of fire safety. 8.2 Key fire safety challenges 8.2.1 Developing educational buildings on a larger existing site presents certain challenges during the construction period for fire safety. These may include:

 Ensuring that means of escape from the existing areas are not adversely affected;  Ensuring that fire and rescue service provisions for the existing areas are being maintained;

 Limiting possible fire spread in between the construction site and the existing neighbouring buildings. 8.3 Possible suitable construction solution 8.3.1 It is expected that a full construction phase fire safety strategy be developed to be implemented on site during construction. This strategy should include an assessment on the likely impact of the site on the existing areas and ensure that adequate mitigation is proposed. It is expected that procedures will be employed to evacuate both the construction site and the neighbouring school building in a fire scenario on either side of the hoarding line. 8.3.2 With respect to means of escape of operatives on site, to meet the recommendations of JCOP and HSG168, at least one protected stair should be provided from the building, assuming that temporary access will be provided throughout the building to enable access to all haki stairs and internal stairs. It would be recommended that the proposed stair cores be utilised for this purpose, including suitable security / safety provisions to separate occupied areas from the construction areas. Enclosure of these stairs during construction would require that any penetrations into the core are temporarily fire-stopped, until such time that the permanent fire-stopping is installed. Temporary self-closing fire doors should also be provided to each protected core, and these should achieve a rating of FD30S or better. 8.3.3 It would be recommended that haki stairs remain in place until such time that the proposed stairs can be safely utilised and are available for beneficial use. Any early removal of the haki stairs should be subject to conducting a fire risk assessment and implementing suitable alternative control measures. 8.3.4 Control measures such as no storage zones, designated storage areas and policies for the daily removal of waste are recommended to assist with the prevention of combustibles accumulating in escape routes.

Furthermore, the disabled refuge EVC systems and supporting management procedures should be interconnected to cover both buildings at the same time. 6 It is critical that school management including any prospective insurers are made aware of the fact that fire spread in between the two buildings is possible from a property protection / business continuity / insurance 6.33 m point of view. Should any party not agree with the potential loss of both buildings in a fire scenario, then options could be investigated to mitigate fire spread, however this are likely to be highly onerous.
