    Fire Doors and training
  1. fire door seals: with or without brush

    The point about fire doors is that if you can identify the fire door to it's manufacturer and relevant evidence of performance, then any components fitted or replaced to make up the fire door assembly should be 'as tested'. That means the fire door should be installed and maintained so that all components and installation data replicates the fire door assembly as it was 'fire performance tested'. For example if the BWF-Certifire label on the door leaf top edge shows the 'CF number' you are then able to download the certificate and data sheet from the Warrington Certification website and therefore install or maintain the fire door in accordance with the data sheet to ensure compliance. BUT many existing fire doors cannot be identified to a manufacturer and evidence of performance. So in this scenario there is no data to tell us what type of fire seals are necessary. In this scenario a self-adhesive fire seal is better than none. Because fire door core construction types vary so greatly, so do the requirements regarding installation and components. If in doubt seek expert advice.
  2. fire door seals: with or without brush

    Self adhesive fire and smoke seals are available https://www.safelincs.co.uk/fire-door-seals-surface-mounted-intumescent-fire-and-smoke-seal-kit-product-1/?fGB=true&gclid=CjwKCAiAoNTUBRBUEiwAWje2lqpip9-5-BwL6n6Ikh2T8e9TFx9FgEfKJhrc-ZPElkVMQ_i0EBKjXRoCf5sQAvD_BwE
  3. Hi Kevin, I am assuming here we are talking about timber based fire doors? The important thing is that the fire door is fitted in strict accordance with the manufacturers installation instructions. Depending on the manufacturer those instructions may make reference to the requirements of BS 8214 the Code of practice for Timber based fire door assemblies. If so you will need to refer to both documents (the British Standard and the manufacturer's instructions) for component selection and installation criteria. If the fire door leaf is certificated under the scope of the BWF-Certifire scheme you will find a label on the top edge of the door leaf. On this label you can find the manufacturers contact details and a number with the prefix 'CF'. If you go to https://www.warringtoncertification.com/certifire/technical-schedules.html you can find the data sheet applicable to that CF number. That data sheet will provide information about component compatibility and installation requirements. The data sheet and installation instructions may not provide information about installation of cold-smoke seals so it will be helpful to get information from the Intumescent Fire Seals Association website at http://www.ifsa.org.uk/documents/ FENSA are correct there is no legal requirement for certification for the installer but evidence of fire (and smoke) performance is required for the products. In England and Wales the 2005 Fire Safety Order refers to the 'competent person' so as you are installing fire safety devices you may have an obligation under the scope of fire safety law as that competent person. Competent Person is defined at the HSE website http://www.hse.gov.uk/involvement/competentperson.htm Finally, training for fire door installers and maintainers is available and so is worth some consideration. Hope this helps, Neil.
  4. Cracks in laminated glass

    Laminated fire glass is not toughened and so must be treated with care. Its the lamination that provides the fire and heat protection seethe video at Some fire resisting glass is tempered rather than laminated and so can withstand greater shock. Contact a fire glass specialist and specify your requirements.
  5. How to upgrade a door to a fire door?

    Hi Eddie, Fire performance products must be installed in accordance with supporting evidence from a fire test report or assessment. If you are proposing to over board a door to improve its fire separation performance make sure you refer to the product data sheets to check suitability of the board for that application. You will also find the above mentioned article, about upgrading doors, useful with regard to the numerous components of the door assembly that contribute to its fire and smoke separation performance.
  6. Chain on fire door

    The flat entrance door as well as being a fire resisting door is essentially a security door too because it opens onto the common area. Therefore a face-fixed security chain like the one in the image below below is allowed. It does not need to be fire rated because its purpose is solely security and it has no contribution towards the fire separation qualities of the door BUT it must not interfere with the self-closing action of the door. You are right to fit thumb turns on the inside so as to aid safe escape from the flat in an emergency.
  7. FD30 door alignment

    You are correct to raise misalignment as an issue as it would affect the door's performance in a fire. The amount of misalignment permissible varies from zero to very little depending on the core construction of the door. Generally speaking a tube-core construction fire door will have zero but a completely solid core will have some tolerance. Ideally you would know who the manufacturer is and check their installation data sheet but in many cases the manufacturer is unknown. The following links are worth a look.......https://www.falconpp.co.uk/media/1155/14_flamebreak_fire_door_installation.pdf they allow 1mm and http://www.hazlin.com/images/Halspan-Optima-FD30-Specific-fitting-instructions.pdf again 1mm
  8. Do bathroom doors need to be fire rates?

    I assume you have fire doors from the bedrooms to the hallways and landings?
  9. Fire door signs

    Hi, Not a silly question at all. The doors you described are designated 'Fire Door Keep Locked' and do not usually have self-closing devices but it is a requirement that they are kept locked. They must be unlocked only for the short period when access is necessary. These doors must be signed with the blue/white or blue/silver "FIRE DOOR KEEP LOCKED"signs. Signs must be prominent and clearly readable on the outside face of the door leaf at about 1500mm from floor level.
  10. Fire rated solid brass Europrofile cylinders

    Hi Fadi, I would add that it is of course the 'lock-bolt or latch-bolt in its keep' that will help to hold the door closed in a fire situation. As far the fire performance tests are concerned the manufacturer will have test evidence for his products used in timber or metal doors. Please note that test results of components used in metal doors should not be used to substantiate performance for timber doors and vice versa. Timber fire door manufacturers' data sheets and instruction manuals will specify the requirements for locks and latches as well as providing installation requirements.These documents are generally available for FD30 and FD60 on-line. Regards, Neil.
  11. Fire Door Inspection

    It may be useful to add that the HSE at http://www.hse.gov.uk/involvement/competentperson.htm defines Competent Person as.....someone who has sufficient training and experience or knowledge and other qualities that allow them to assist you properly.
  12. Fire Door Inspection

    Hi Steve, There is a legal requirement under the Regulatory Reform (Fire Safety) Order 2005 for employers (and other Responsible Persons) to: (a)take such general fire precautions as will ensure, so far as is reasonably practicable, the safety of any of his employees; and (b)in relation to relevant persons who are not his employees, take such general fire precautions as may reasonably be required in the circumstances of the case to ensure that the premises are safe. Article 17 of The Order says they......must ensure that the premises and any facilities, equipment and devices provided in respect of the premises under this Order or, subject to paragraph (6), under any other enactment, including any enactment repealed or revoked by this Order, are subject to a suitable system of maintenance and are maintained in an efficient state, in efficient working order and in good repair and Article 18 of The Order says.....The responsible person must, subject to paragraphs (6) and (7), appoint one or more competent persons to assist him in undertaking the preventive and protective measures. Fire Doors and Escape doors are 'equipment and devices' and must be kept 'in an efficient state etc' (see above) therefore inspection must be part of the suitable maintenance regime. BS 9999 and BS 8214 recommend regular inspections of Fire Doors. You can find your nearest Certificated Fire Door Inspector at http://www.fdis.co.uk/inspector Alternatively you could enrol on a suitable course at http://www.fdis.co.uk/qualify-with-fdis or https://www.bre.co.uk/news/New-dates-announced-for-fire-door-inspection-training-935.html or https://www.door-check.co.uk/training or https://www.firedoorscomplete.com/fire-door-training My October blog at https://www.firedoorscomplete.com/single-post/2017/10/12/Fire-Door-Monthly-Fire-door-law-the-competent-person-and-relevant-training talks about competence and training.
  13. Fire resisting glass products have been available for many years but as with all fire and smoke compartmentation its about correct installation of the correct system so I would advise consulting a fire resistant glass expert. There's useful info on fire resisting glazing in the document 'A Guide to Best Practice in the Specification and Use of Fire-Resistant Glazed Systems' at http://www.ggf.org.uk/publication/FRGbest
  14. Fire doors in a domestic 3 storey house

    Hi Tony59, Being built in 2000 the doors should be fire doors. You reference "DALE 90623" so the doors are most likely made by Dale Joinery in which case I suggest you contact Ian Cavanagh CertFDI via the search facility (he's based at Rochdale but should be able to help over the phone) at www.fdis.co.uk/inspector for advice. Kind regards, Neil.
