3 Certification BEFORE ANY WORK IS UNDERTAKEN ON ANY FIRE DOOR YOU MUST CHECK THAT THE DOOR DOES NOT HAVE ANY CERTIFICATION LABELS. IF IT DOES YOU MUST FOLLOW THE ADVICE GIVEN FOR THAT DOOR OR THE CERTIFICATION WILL BE VOID. CERTIFICATION MARKS ARE SHOWN BELOW & WOULD USUALLY BE ON THE TOP OR HINGE EDGE OF THE DOOR Fire door signs All fire doors must be signed using one of the following standard signs. For mental health wards please seek advice from the Trust Fire Officer Fire door keep closed: Positioned at eye level on outer facing part of door. Corridor doors shall have signs fitted at both sides. On double leaf doors, signs shall be fitted on both sides (and both leaves if a corridor door) Fire door keep locked: Positioned at eye level on outer face of door. To be used on fire doors that are not fitted with self-closers and are designated hazard rooms (ie store cupboards, service risers, plant rooms and laundries) Automatic fire door keep clear: Positioned on visible open leaf at eye level. Used on doors connected to automatic hold open devices that release the door on activation of the fire alarm Fire doors (General) FD30s doors generally shall not be less than 44mm in thickness FD60s doors generally shall not be less that 54mm in thickness

4 Where fire doors are required All sites containing sleeping accommodation The requirements of Firecode must be met. All doors leading on to an escape route must be fire doors. All hazard rooms must have a fire door fitted (these are detailed below) Ward areas: All doors that lead on to a corridor must be fire doors Communal bathrooms in mental health wards must have fire doors fitted Hazard rooms include Cleaner s stores/cupboards. Clothes or linen cupboards. Laundries. Staff changing rooms/locker rooms. Store rooms. Ward kitchens. Medical record stores. Stationery Cupboards. Contractors/workmen s stores.

6 Door leaf & frame The selection and installation of the door and frame is very important. Where purpose built frames are installed they shall be matched with the recommended door, as the fire resistance of one may depend on the design features of the other. Fire doors must be supplied by the company that has designed, tested & manufactured door themselves. Cascaded evidence is not acceptable New or replacement fire doors must be solid core or flaxboard core with at least 10mm solid wood lippings. In high traffic & in-patient areas these should have a laminated face with edge protection fitted. Please see Appendix 3 & 4 No work is to be carried out on the top edge of the door (head) Fire doors shall fit close to the frame with a 3mm gap allowed; the gap must not exceed 5mm. Any gaps between the frame and the wall must be in-filled with the appropriate fire stopping material (Please see below & Technical Note 1) When intumescent material on the frame faces the same on the door edge, they must be the same type New door sets will not be accepted, unless accompanied by the appropriate test evidence. Cascaded evidence is not acceptable If a new frame & door is required these must be produced under the control of a single manufacturer that is responsible for the evidence of performance of the fire door Please see BM TRADA Accepted Repair Techniques: ART 1, 3, 6, 7, 9, 17, 18 and 20 at the end of this section Everbuild Fire Sealant 300 can be used to repair surface damage to non-certificated fire doors. The damage must be no more that 50mm wide & deep. Please see the appendix 1 at the end of this section for further information A filled penetration can be covered with impact protection. Metal plates must not be used to cover any penetrations unless they have been filled Threshold gap The threshold gap must not exceed 10mm. If it is more than 10mm then a face fixed or drop down threshold seal must be fitted. Please see section on intumescent & cold smoke seals for further information Door frame Door frames at community sites can be softwood, except in high traffic areas where hardwood should be used Door frames for in-patient buildings must be hardwood. The frame must be as deep as the aperture will allow & be fixed to the wall & the door with the maximum length screws possible Architrave to wall gaps The frame must be fixed securely to the surrounds, with the gap not exceeding 10mm between the frame and the wall. 0-6mm gaps must be filled with Pyroplex intumescent mastic. Gaps over 6mm must be packed with mineral fibre & then capped off with Pyroplex intumescent mastic. The specification for the fire stopping used, must be placed in the buildings fire manual. Please see Appendix 2 & the Fire technical note 1: Passive fire protection which is available from the Trust Fire Officer Door Protection Laminate faced doors must be considered when installing doors in high traffic areas or areas where the doors may be vulnerable to abuse. Impact protection should also be fitted to doors frames & door leaf edges in areas where damage may occur.

7 Impact protection can also be retro fitted to an existing door after consultation with the Trust Fire Officer Manufacturer s instructions The manufacturer s installation instructions & product types must be followed when fitting any new fire door Making changes to how a fire door is installed If any changes from the manufacturers instruction are required when fitting a fire door advice must be sought from the Trust Fire Officer prior to these alterations. This ensures that we have an evidenced tested solution from the door manufacturer to the changes that are made

23 Intumescent and cold smoke seals The area where the door leaf meets the door frame is the part most susceptible to penetration by fire and cold smoke. Please see BM TRADA Accepted Repair Techniques: ART 4, 11 and 22 at the end of this section An intumescent strip can either be fitted in the door frame or in the door edge itself and must be centrally fitted. Intumescent strips must not be fitted to the bottom edge of the door as the door will be forced open as the strip expands. The different types of intumescent seals are not interchangeable. If you are unsure of the type used the complete seal must be replaced. If the type of seal is not known a Pyroplex brush intumescent & cold smoke seal must be used All new doors must have Pyroplex brush intumescent & cold smoke seals If intumescent or cold smoke seals become damaged they must be replaced with the identical product. If unsure of type used the complete seals must be replaced Intumescent and cold smoke seals must be fitted to the top edge and both sides of the door, or frame, they must not be fitted along the bottom edge FD30 doors generally shall not be less than 44mm in thickness o Intumescent strips and cold smoke seals can be interrupted for hinges and latches FD60 doors generally shall not be less that 54mm in thickness o Intumescent strips and cold smoke seals are generally fitted in double strips. One strip must be uninterrupted and the other can be interrupted for hinges and latches. Single strips of 30mm wide can also be fitted, but these must be uninterrupted. When a door is required to have cold smoke and intumescent seals this is should be achieved by using a single strip combining both functions. If this is not possible please seek advice from the Trust Fire Officer Intumescent and cold smoke seals must be protected during painting. If paint covers the cold smoke seal it must be replaced. In in-patient areas the intumescent & cold smoke seal must be cut every 300mm & then pinned into the rebate to reduce the ligature risk Permissible gaps around the door 3mm gaps are permitted in the head, opening & closing edge of the door Up to 10mm gap is permitted at the threshold edge. Drop down threshold or face fixed seals are required if the gap exceeds this Threshold gap The threshold gap must not exceed 10mm. If it is more than 10mm then a face fixed or drop down threshold seal must be fitted. Community buildings & non-patient areas of in-patient buildings: A face fixed threshold seal can be fitted if the gap is less than 15mm. Please see appendix 6 In-patient areas: A drop down threshold seal can be fitted if the gap is less than 15mm. Please see Appendix 5

29 Hinges Hinges fitted to fire resisting doors must achieve the intended fire rating, also the hinge must be able to allow the door closing device to close the door fully to latch Generally all doors on escape routes shall open in the direction of emergency travel. For further advice please speak to the Trust Fire Officer At the same time, where escape route doors are part of the final exit from a building, there will be some additional requirements for security of the door against intrusion and burglary. In this case the hinges shall be of a design so that they cannot be removed or parted whilst the door is closed, ensuring that the building and its contents are secured against unauthorised entry. Where escape route doors are part of the fire compartmentation of the building, there will be additional requirements to ensure that the hinges fitted meet the same fire-resisting performance of the door set. For hinges in in-patient areas anti-ligature continuous geared hinges or anti ligature secura hinges should be fitted. Please see Appendix 7 & 8 for fixing instructions Please see BM TRADA Accepted Repair Techniques: ART 8, 13 and 15 at the end of this section Hinges in community buildings must be a bushed bearing hinge that is: CE Marked to BS EN 1935, including its Annex B. This document is available from Bradford District Care Trust Fire Officer if required. Provided with certification by an approved third party certification body. The strength and features must be correct for the size of door and weight to which it is to be fitted, bearing in mind: o The use of the door (main entrance, toilet lobby, duct door), o Position of door stop if being used (position on floor or wall in relation to width of door) o Whether subject to factors such as heavy traffic use, abusive treatment o Whether or not a door closer is being used o Height and width and weight of the door and number and position of hinges o Whether the door is on an accessible route and therefore must to satisfy Part M of the Building Regulations The following type of hinges are not permitted on Trust fire doors Rising butt hinges Spring hinges Lift off, loose pin and journal supported hinges Ball bearing hinges General information about hinges on fire doors For timber doors and frames, fixing screws shall be not less than size No.8 (3.8 mm) and not less than 30 mm in length. Some fire doors are being manufactured with Graduated Density Core materials. These require a longer fixing screw of at least 50mm. If there is any doubt, advice must be sought from the door manufacturer regarding the material of the door core.

30 For timber door leaves of 44mm thickness part of the hinge shall extend across the door thickness to a position closer than 12 mm from the opening edge. For timber door leaves of 54 mm thickness no part of the hinge shall extend across the thickness to a position closer than 18 mm from the opening edge. If intumescent material was used when the hinge was fire tested, it is essential that the same material be used in order for the test evidence to be valid and maintain the integrity of the door set. If the hinges require packing Pyroplex hinge pads. Cardboard must not be used to pack hinges under any circumstances If the hinge rebate is too large Pyroplex intumescent mastic must be used to fill the gap Hinges must have a minimum melting point of at least 800 C Number and Position of Hinges It is usual for at least 3 hinges to be fitted on fire and escape route doors. With fire-resisting doors becoming heavier, two hinges are required at the top of the door with the third hinge at the bottom of the door. The door manufacturers guidelines must be followed, it is unsafe to alter the as tested position of a hinge on a fire door, without assessment from a suitably qualified authority. For doors heavier than 160 kg or exceeding 2000 mm in height and 1000 mm in width, a recommendation from the hinge and/or door manufacturer shall be obtained. Annex D of BS EN 1935 gives additional advice regarding the use of hinges on doors of excessive width. (A wide door is one where the width is more than half the height.) This document is available from the Bradford District Care Trust Fire Officer on request.

37 Locks and latches In order to provide an effective barrier to a fully developed fire, a door has to remain closed within the frame. The addition of a lock or latch to a fire-resisting door set can reduce the fire performance of the door set. The reduction in the amount of wood in the stile or rail can also impair the stability of the door, leaving it less able to resist distortion caused by the heat of a fully developed fire. Where security is in conflict with easy egress, consultation with the regulatory authority or fire officer must be made in order to reach a satisfactory solution. Please see BM TRADA Accepted Repair Techniques: ART 12 at the end of this section A locked fire door must be able to be opened with a single action; this can be achieved by fitting one of the following A thumb turn lock A panic bar An electronic lock which releases on fire alarm activation, this must also be accompanied by a green break glass In fitting locks or latches to fire-resisting door sets, the potential fire performance of the door set can be reduced due to Removal of a section of the door leaf, door frame or seal. To minimise this, the locks and latches shall be as small as is practicable. Leaving voids within the structure of a timber door, Adding materials which could cause heat transfer problems in a timber door, Through fixings creating thermal bridges in a timber door, using materials of low melting point (less than 800ºC) Locks containing materials which might flame. The lock or latch must be CE marked to BS EN Provided with additional product certification by an approved third party certification body. Section 6: Lock and Latches Page 61 Voids in the Structure of the Door All mortising in fire-resisting timber doors must be performed as accurately as possible to avoid creating unnecessary voids. Clearance holes for keys, cylinders and spindles must be no larger than the sizes specified on the manufacturer s fitting instructions. If the latch or lock specifies the fitting of some form of intumescent protection and/or use of covered escutcheons, these must be used to ensure that the fire resistance of the door is no less than when tested. The following types of door hardware are not permitted on any Trust fire door Roller ball catches Rim latches Bored-in knob sets

38 Mortise latches and locks Mortise latches are normally mortised into the door edge. Please see BM TRADA Accepted Repair Techniques: ART 2 at the end of this section Where mortise locks are provided, the cut-out in the door must be the minimum necessary to prevent any voids which fire can penetrate. After the edges, the mortise lock and latch areas represent the next zone of weakness. Any voids in the cut-out must be filled with intumescent paste to lessen the weakness in this area. As the latch is the only holding device on the closing edge, it is important that it must be strong and that the nib of the latch must engage into the latch plate at least 12 mm to ensure that the closing edge will not spring open when the door deforms. Extended flap latch plates are required for one-hour doors. The lock or latch shall be CE marked to BS EN and shall have additional product certification by an approved third party certification body. The Trust requires that pairs of timber fire doors have plain edge stiles with a conventional latch and striking plate rather than rebated meeting stiles with forend conversion units. However, providing there is satisfactory fire test evidence, timber rebated doors with their appropriate fittings may be permitted. As mortise locks are generally larger than latches, the amount of wood removed in fixing and the extra amount of metal introduced can make the reduction in fire integrity that much greater. Any voids in the cut-out must be filled with intumescent paste to lessen the weakness in this area. Digi locks Digi locks must not be fitted on any fire door due to the large penetration through the door leaf. If a Digi lock is required a Coded handle E3100 (Assa Abloy) can be used but must be approved by the Trust Fire Officer prior to the work being agreed. Please see Appendix 9 Lever handles and knobs Fire-resisting door sets usually incorporate either: Lever handles or knobs if the doors are latched, or Pull handles/push plates if unlatched. Lever handles and knobs must comply fully with: BS EN Building hardware - Lever handles and knobs This evidence must be provided by an approved third party certification or testing body. Pull handles must comply fully with: BS 8424 Building hardware, Pull handles, Requirements and test methods This evidence must be provided by an approved third party certification or testing body. All door furniture must have demonstrated its suitability for the intended purpose, by inclusion in satisfactory fire tests to BS 476:22, BS EN or BS EN , on a type of door set and configuration on which it is proposed to be used. This evidence must be provided by an approved third party certification or testing The use of intumescent sleeves around the fixing holes is required for timber doors. The material used in the construction of lever handles, knobs and pull handles/protection plates has not been found to greatly affect the fire performance of the timber door sets to which they are fitted. Generally it is also true that the actual size of the lever handle or pull handle has no effect upon the fire performance of the doors to which it is fitted.

44 Glazing including vision panels If vision panels or glazing is required in an existing fire door or partition then a new fire door is required Fire-resistant glass must only be used as part of a fire-resistant glazing system which includes the glass, the glazing seals, glazing beads, fixings and frame. Glazing for fire doors must be 10-12mm Pyrobellite. Temporary repairs can be made with 10mm clear polycarbonate All the essential components of such a system must be compatible under fire conditions and the performance must be referenced to appropriate and relevant test evidence Please see BM TRADA Accepted Repair Techniques: ART 14 at the end of this section What is required when glazing is fitted? Official evidence from a competent authority demonstrating the fire resistant performance of the glazing system used Evidence of installer competence (e.g. UKAS-accredited certification body) Permanent stamp on the glass that indicates as a minimum, the name of the glass product and the manufacturer/supplier and possibly the fire performance rating The stamp must be visible and readable after glazing Any necessary refurbishments must be carried out according to the approved original specification for the glazing system and shall be completed on a like for like basis All components must be replaced with a new, complete and approved fire-resistant glazing system if the original glazing system specification cannot be established or was originally specified incorrectly Intumescent seal types for glazing Intumescent seals are based on materials that expand and foam on exposure to heat. The degree of intumescence and the expansion pressure vary according to the material and its formulation. In particular, the following must be noted Sodium silicate and graphite based materials may have a high expansion pressure which means they have to be used and applied carefully as the application of too much material may push the beads off, leading to premature failure Ammonium phosphate materials do not show expansion pressure to the same degree, but if the expansion is too great then the density of the material left in the gap between the glass and the bead may be too low to inhibit erosion leading to premature failure Pre-formed strips of intumescent compound ensure that the correct thickness and amount of material is applied. Intumescent seal strip materials may be unprotected if they are composed of a material that is not particularly sensitive to moisture and they will generally have a self-adhesive layer to fix to the bead

45 Glazing bead Anti-Tamper screw fixings, counter sunk flush, as pictured, to be used on glazing beads Replacement Vision Panels To fit a replacement vision panel to an existing fire door the technical specification in the Vision Panel guidance must be used. This is available from Estates Maintenance or the Trust Fire Officer Vision Panel must not be fitted to a fire door that currently does not have one fitted without seeking approval from the Trust Fire Officer

46 Emergency glazing repair 240mm coach bolt M12 nylock nuts to clamp plus washers Emergency Glazing repairs should avoid fixing anything directly to the face of the door or damaging the door in anyway. If the broken glass cannot be held securely in place using a film and the area needs boarding please see below for how to temporarily repair the door In an emergency situation please follow the below steps Carefully remove and clear any broken glass and dispose of, remove the beading if necessary. 2x 18mm ply boards should be cut oversized by a minimum of 50mm all-round if possible so they sit on the outside of the door on either side of the glazed area. The boards are to be clamped together with 4x 240mm coach bolts & M12 nylock nuts as detailed below. These bolts should be fixed in each corner of the original glazed area so it stops the temporary boarding being slid in any direction. The coach bolt must be on the patient side of the door to reduce the ligature risk

49 Panic and emergency exit devices Push pads must not be fitted on any Trust door, Exidor panic bars must be used where required Signage must accompany all panic bars stating how they are operated Experience relating to escape from buildings and general safety has shown the importance of fitting doors on escape routes with suitable exit devices to enable the occupants of the building to escape quickly and easily in the case of fire or some other emergency. Factors to consider include: Different groups of users will have differing requirements to enable them to make an effective escape and this has to be reflected in the type of device chosen. Where escape route doors are part of the final exit from a building, there will be some additional requirements for security of the door against intrusion and burglary. In this case there can be a conflict between the requirements of building users to be able to escape easily and the requirements of building owners to secure their building and its contents against crime. Where escape route doors are part of the fire compartmentation of the building there will be additional requirements to ensure that the escape hardware fitted does not compromise the fire-resisting performance of the doorset. Devices intended for use must be CE Marked to BS EN Panic exit devices operated by a horizontal bar, and preferably provided with additional product certification by an approved third party certification body. Devices for use on pairs of doors shall have been specifically tested and approved for that purpose. Care must be taken that hinges and any seals are correctly fitted so that the escape doors are able to open freely once the exit device is operated. No additional security devices must ever be fitted to escape route doors unless specifically approved by the Trust Fire Officer Section 12: Panic and Emergency Exit Devices Page 97 The exit device and any accessories shall have demonstrated their ability to be suitable for the intended purpose, by inclusion in satisfactory fire tests to BS EN or BS EN , on the type of timber doorset and configuration in which it is proposed to be used. This evidence must be provided by an approved third party certification or testing body. The Building Regulations (England and Wales) 2000 Approved Document B 2006 Edition requires that all doors on escape routes be fitted with escape hardware that is simple to operate and does not require specialist knowledge or tools for its operation (e.g. panic bars).page Break-glass emergency bolts must not be used on emergency exit doors in any Trust building

51 Door closers If a closer is required on a fire door a Dorma TS92 cam action closer must be used. Please see Appendix 10 If a closer is required that does not add any additional opening force to the door (ie in elderly wards) then a Dorma TS73 EMF free swing door closer can be used. Please see Appendix 12 For closers in ward areas Closers in non-patient areas on the wards should be Dorma TS92 cam action closers. Please see Appendix 10 For closers in patient areas a Safehinge Symphony closer must be used. Please note this closer requires a 54mm door. If this closer is not already fitted to the door a new frame will also be required. Please see Appendix If a frame mounted free swing closer is required a Dorma RTS 87-RTS80 EMB closer can be used. Please see Appendix 11 Rack and pinion closers should not be used on Trust fire doors Freedor Any requirement for a Freedor must be approved by the Trust Fire Officer. Please see Appendix 12 Dorguard Any requirement for a Dorguard must be approved by the Trust Fire Officer. Dorguards must not be used on corridor or hazard room doors unless approval is given by the Trust Fire Officer Please see Appendix 13 Please see advice from the Trust Fire Officer for other options

70 Other Components Pull handles, kick plates, push plates, letter plates & spy holes (door viewers) Pull handles shall use bolt-through fixings, rather than face-fixed screws, as these will prove more durable. The heads of the fixing bolts shall be protected by a push plate or rose. Door protection (kick) plates fitted at the bottom of the door have not been shown to have any effect on the fire performance of timber door sets. Push plates of conventional sizes, which can be screwed or adhesive-fixed, can also be fitted without problems. Letter plates must not be fitted to any fire door Door viewers/spy holes must not be fitted to any fire door unless the door viewer model is supported by evidence of fire performance in a door of the relevant material & has been approved by the Trust Fire Officer prior to the start of any work. Please see Appendix Air transfer grilles Air transfer grilles in fire doors will not only allow air to pass through but fire and smoke. It is essential that any air transfer grille fitted to a fire door does not reduce the fire and smoke resisting properties of the door. Air transfer grilles will only be permitted on any fire doors, once all other methods of venting have been explored. Any air transfer grille fitted to a Trust fire door must be interfaced with a fire alarm & activate on heat & smoke Air transfer grilles in fire doors shall not be fitted higher than 1000mm from the bottom of the door. Please speak to the Trust Fire Officer before specifying any air transfer grille
