  2. Be careful about generalisation with regard to timber-based fire door installation requirements. The image below is an example of intumescent gasket requirements for hinges for an FD30 timber-based fire door:
  3. Fire fire doors, with regard to restricted smoke spread the excerpt above is from building regulations in England & Wales Approved Document B, Table C1. Looking at 2a it can be seen that smoke leakage is allowed but not exceeding the stated rate, from the head and jambs only. There is no mention of the threshold gap. Section 12.3 at BS 8214:2016 provide specific guidance about the gap at the threshold and the following information from www.ifsa.org.uk may be useful: "Because it is perceived to be difficult to achieve a seal at the threshold, the gap at the bottom of the door is
  4. This type of self-closing device is installed into mortice holes in the top edge of the door leaf and door frame head. The arm is connected at the device and at the door frame head. The top edge of the door is partially scalloped to accommodate the arm. It is important to understand that only specific timber-based fire doors are suitable for this type of self closer, they must have evidence of fire resistance performance when fitted with the particular self-closing device. Furthermore, certain additional works will likely be required such as thicker hardwood lipping at the door lea

  6. Hi AnthonyB, thank you very much as always. That's really helpful with our discussions with the client.
  7. It depends on the door and the certification it has.if I had to say ‘generally’ it would be that maglocks using through-door fixings should not be fitted where avoidable and definitely not above a glazed aperture.
  8. I expect you mean an intumescent air transfer grille? These do not restrict the spread of cold-smoke, so only where the fire risk assessment allows.

  10. Yes, as that requirement was in existence at the time of build and unless you have insurance and building control approval for the effective removal of the system you are in sticky water before even considering the Fire Safety Order! If you split it into compartments that are below the threshold you may be OK - this is common in former large open single occupancy warehouses that are subsequently sub divided for multi occupancy - as the building work creates compartments below the threshold Building Control does not require the sprinklers and the insurers usually likewise. It sounds like
  11. That diagram reflects the actual text far better!
  12. It's not an automatic requirement for existing buildings and depends on the individual circumstances - many account for the lack of a system in their PEEPs and allocation of individual buddies to be with them & help them evacuate when the main flow has passed.

  14. Hi all, I need some help please, can a fire door have a lip cut at the top of the door for the instalation of a concealed door closer so as the arm does not bind on the door?The closer part is fitted to the underside of the door frame and arm is fixed to the top of the door, i hope this makes sence Thanks
  15. Hi, we have a quick question regarding a new restaurant we are managing for a client. fairly small with each floor level approximately 250-300sqm. Ground and basement only. Mixed purpose groups above (offices and some flats higher up). Kitchen is at rear of ground floor. Client wants open servery. Basement is served with single stairway only. Once at the top of stairs, customers have to head towards front entrance / exit doorway which leads to high street. Distance from top of stairway and the wall / door / servery to kitchen will be approximately 3-4m. Looking at L2 f
  16. A fire risk assessment determines should a fire alarm be installed or not, and if so to what category. Regarding your other points this is a fire safety forum, and as such we can not help you other than to suggest you read your contract and seek legal advice. 🙂
  17. Stand alone carbon monoxide detectors detect carbon monoxide and should be installed near something that may give off carbon monoxide, such as a boiler, there is no point in having them in a room where there is no means of producing carbon monoxide. It has been known for a carbon monoxide detector to activate at what appears to be random, and only for a short time (Such as happened to you) If this happens and the carbon monoxide detector stops and does not repeat then it is probable that there was a small pocket of carbon monoxide that has since dissipated, and is nothing to worry about.

    Fire safety & damp

    Hi all I recently started rental on a business property that once was a sunbed shop and also was offices. To my surprise there was no fire alarm system in place and the electrical work was unsafe and cost me (the tennant) an additional £1000. Should this be the landlords responsibility to install or both parties? Also there was a leak ion the roof (which was repaired by landlord) but the re studding and plastering was paid for by me, is that correct also? Many thanks
  19. We have a warehouse used for paper (2.5ton reels) which is over 20,000msq. Approximately 40,000msq to be fair! Originally built 30(ish) years ago. Had (past tense) a sprinkler system fitted. Problems occurred when sprinkler pipes began to leak, causing damage to paper stock. Resulted in customer complaints, so the then owners decided to disconnect the sprinkler system...avoids paper getting damaged and saved maintenance costs of sprinkler system. 🙄 As the building originally had a sprinkler system, must the Responsible Person (new owner) reinstate the sprinkler? I can see Buildi
  20. the door should resist passages smoke to a given performance standard when pressurised from one side at “ambient” temperature to limit the amount of cold smoke passing from one side to the other. The requirements specifically exclude any performs for the threshold, the key point is that ADB only requires the head and jambs to have a performance form standard in respect to cold smoke leakage. When pressurisation is being used in a building as part of the active fire safety provisions then the requirement for smokes seals on the threshold of doors is increase and it is these conditions word thre
  21. The Regulations do not apply to furniture intended for export and furniture manufactured prior to 1950. Check out https://www.firesafe.org.uk/furniture-and-furnishings-fire-safety-regulations-19881989-and-1993/ so the level of fire resistance will be up to you but I would mimic the regulations for peace of mind. You could include a label that indicated that the item was manufactured pre 1950.
  22. Hi, Do refuge points require a communication system or could this be detailed in the PEEP? Thanks Louise
  23. There is no requirement to fit intumescent packers on a FD30 door, however any packers fitted should be
  24. Can you put an intumescent block in the hole
  25. Hm... What about this diagram? Here 4.5m is almost at ceiling level, so can't be showing window height?
  26. Can anyone tell me if there is any specialised guidance for carrying out an assessment in a large Grade 1 Listed Building that is open to the public...I have GN80 and also large places of assembly for reference at the moment?
  27. For this type of door, the maximum threshold gap should be 3mm because building regulations require the fire resisting doors in common areas of blocks of flats to provide restricted spread of cold smoke. Refer to BS 8214:2016 Timber-based fire door assemblies - Code of practice, section 12.3. The use of a suitable threshold plate will certainly make it much easier to achieve this gap and Building Regulations Part M compliant ones are available. However, if a hazard assessment has ruled them out it will be necessary to fix a hardwood lipping to the door leaf bottom edge and/or fit a drop
  28. For a double-swing-action timber-based fire door it will be necessary to use pivots instead of hinges. It will likely be necessary to use a floor=spring instead of an overhead self-closing device. Not all timber-based fire doors will be suitable for this application, so consult a specialist fire door supplier/manufacturer. And follow the installation instructions for that particular door leaf.
