  2. Whilst it is bizarrely not mentioned much in UK guidance it is true that in the US and the many countries that follow US guidance that the use of ABC Powder where it can come to rest on the superstructure and in the engines of aircraft is not permitted or not recommended as the acidic ammonium phosphate & sulphate has been shown to cause fatigue in aluminium so to avoid structural integrity risks (& at the very least a 5 or 6 figure cost full stripdown and clean) only alkaline Sodium or Potassium Bicarbonate BC Powder should be used. Now in the US this isn't a big issue as all manufacturers still make various types of BC Powder extinguisher in all sizes but in the UK you are rather limited as nearly everything is ABC. Some manufacturers do a 8kg extinguisher filled with Monnex BC Powder (the most powerful extinguishing powder in the world due to it's Potassium base and ability to decrepitate in flame to increase it's surface area) which is very expensive. Only one manufacturer supplying the UK (also one of the few remaining companies to make extinguishers here rather than China or Poland.) has a variety of different sizes of BC Powder & Monnex extinguisher, including large capacity trolley and skid mounted units, this is Britannia Fire. Amerex UK (an American company) also has 9kg BC Powder and Purple K models ex stock, but because it's a US firm can import any of it's wide range of other BC models if required. I'd have 9kg BC Powder for rapid knockdown with 9 litre Foam (type of foam & delivery may differ depending on risks) for post extinction security. The nature of the risks & any CAA or Insurance requirements may also mandate larger trolley extinguishers etc
  3. The standard for door self-closing devices is BS EN 1154. For a fire door the device should be minimum power-size 3 and have controls for adjustment of closing speed and damping action. Section three of the document 'Hardware for Fire & Escape Doors - Code of Practice' at http://www.firecode.org.uk/Code_of_Practice_hardware_for_fire_and_escape_doors.pdf#:~:text=Code of Practice%3A Hardware for Fire and Escape,on fire-resisting doors and doorsets%2C and escape doors. provides detailed information.

    Aircraft Hangars

    Hi all anybody with knowledge regards portable extinguishers for aircraft hangars, I`m sure I read somewhere that ABC Powder units shouldn`t be inside hangars, not because BS stated about powders indoors but because if there WAS an ABC in a hangar for gas risk or whatever and used, the Acid based powder was dangerous as in it is corrosive to Aluminium and could weaken aircraft joints, ?? apart from LX / HX Foam flooding systems, IF you were recommending portable units, whats the spec? Thanks :)
  6. Unlatched fire doors are obviously solely reliant on the self-closing device to provide an opening resistance which in turn, maintains the leaf securely against the frame stops in a fire situation. However, I cannot find any reference as to what this minimum force should be. Is there a guideline minimum opening resistance and how should this be measured? In more extreme cases, it's generally easy to spot such defects (e.g. communal fire doors opened by draughts) but there must surely be a more scientific method to identify potentially dangerous unlatched fire doors which may not exhibit such obvious failure symptoms? Thanks in advance.
  7. Thankyou Tom and Anthony for your replies. Appreciated to have other more informed views on this subject.
  8. The guidance document BS 8214: 2016 'Timber-based fire door assemblies-Code of practice' deals with threshold gaps for restricted cold smoke spread requirements in section 12.3. So its clear that, when installing fire doors to that standard, the door bottom edge to floor covering/threshold plate gap should not exceed that specified by the fire door leaf manufacturer, this is commonly 6mm to 10mm. Where the door is required to restrict spread of cold smoke the threshold gap should not exceed 3mm. Where a 3mm gap cannot be achieved (due to floor condition) a suitable threshold plate or ramp should be fitted to the floor and/or a threshold seal to the door leaf as necessary. In terms of responsibility, its impossible to answer your question because details of the agreement between you and your client are unknown. Eg. Who carried out the pre-works survey? In my view, the fire door installer should inform the client about threshold gap requirements and recommend suitable solutions (as described above) where gaps are excessive. Hope this helps.
  9. You need a competent person to carry out a Fire Risk Assessment - this will answer all these questions. The FRA is a legal requirement. There's too many possible variables without seeing the place as all your three questions could easily have a yes or a no answer, although with respect to the last one the retail unit should be considering the fire resistance of their ceiling in their FRA as the flat occupiers are 'relevant persons' for consideration under the regulations even though the interior of the flats themselves isn't. If the fire separation isn't adequate then they should ideally upgrade it, otherwise they would need a fire detection and alarm system set up to warn the flats (usually involving sounders in the flats)
  10. As you had your windows open anything could have blown in (Carbon monoxide is colourless and odourless) and as it did not continue I would say it was a pocket of gas and nothing to worry about.
  11. We manage our own Management Company. It's a block of 12 flats, 6 Flats on the 1st Floor & 6 Flats on the 2nd Floor, above retail premises (which project further back than the rear Boundry line of the Flats). Purpose Built in 1986 We have front & rear entrances to/from communal stairways. Walkway between stairwells on both floors is covered, but open to fresh air for the complete length on both floors with Fire Exit doors both ends. 1. Is it a requirement to have Smoke detectors or fire alarms to the communal areas? 2. The Flats have part glazed front doors as specified when built. Are these okay as they must have been when built? 3. I assume that there is fire resistance between the ground floor retail premises. Is it their responsibility to ensure they have adequate fire resistence/ alarms to protect us? Regards AlanB
  12. My smoke/carbon monoxide detector went off at 1am telling me there was a fire, then carbon monoxide. I’ve had a bunch of windows open in the house all night without a problem. It’s the first time this had happened, should I be concerned?
  13. Hi Neil we are a certified company for installation and maintenance on fire doors. However we have been in contact with Iur 3rd party insurers and I couldn’t get an answer to the following. its regarding drop dow seals to FD30S doors. I have read the best code of practice and this question refits to note 1 section 12.3 Am I correct in the understanding of the last paragraph of this where it states that gaps to bottom of doors may not be known untill to lime of installation. im trying to find out if we are responsible for gaps which are over 3 mm and up to 15 mm after finding out that the floor levels ranged from 0 - 15 mm out of level. at the time of quoting we quoted for FD30s and provided an Ironmongery scheduled which did not shot any drop down seals. in my view at the time of rendering were were not expected to know of differing floor levels. we have really been struggling to find someone to give us a clear yes or no. have you any idea on this or could you point me in the right direction to who can give clear advise on this. colin
  14. Check out https://www.nationalfirechiefs.org.uk/write/MediaUploads/NFCC Guidance publications/NFCC_Specialised_Housing_Guidance_-_Copy.pdf you may find some help there.
  15. If the external fire escape serves all floors then it is likely that the kitchen door needs to be an FD30s fire door so you will need to find out if it meets a fire resisting standard.
  16. I would stick to the lacors guidance, front doors to be FD30s fire doors, upgraded or replaced and a grade A in the common areas with a heat detector in the hallway of each flat. Each flat owner should be advised to provide a grade D system in each flat, not interlinked. The alternative fire escape route would be a bonus but not used as a compensatory factor for the principle means of escape.
  17. I would welcome your thoughts on the following scenario I've recently been asked to look at an issue in a care home whereby a risk has been identified concerning residents with dementia being able to traverse the staircases (which serve as primary access and egress for staff and evacuation). At each level the 2nr stair and lift lobbies connect either side of the care home and is required as a throughfare to allow residents to access facilities etc at either sides. Due to the structural layout it is not feasible to enclose the stairs further with say fire doors directly at the head and feet. The simplest solution would be similar to a child gate at the head and the foot of each. I'm assuming that this could compromise evacuation in the event of fire therefore a hybrid/bespoke solution with mag lock linked to fire alarm may suffice. Does such a product exist and does anyone have any experience of this scenario? Many thanks

    If your desired access across adjoining land is not protected in deeds, easement or license then you are in trouble, I had a commercial client where an informal access arrangement was revoked on change of ownership of the adjoining property and it caused all sorts of issues as it remove their alternate escape route - however the resulting fire safety compliance issues were solely those of the client. There are some precedents for informal arrangements being protected if they have existed long enough, but this is definitely an area where you need the advice of a good property lawyer.

    Sorry, but you really need legal advice which this forum does not offer. 😐
  21. Hello Please i will appreciate a clarification on this. We have a supplier to supply a set of dinning chairs and he has given us this information below that this chairs are non uphostered and will not require any fire labelling; this will be for a Medium Hazard Premises( Sheltered Housing Scheme), i have looked around to see whether there is any guidance or legislation for non uphostered furniture & plastics, i can't seem to see any. Can this sort of furniture with discription below be allowed in such care & support schemes.

    Hi, we live in an apartment, bought from our landlord a few years ago. Our kitchen, living space has french patio doors to a small decked platform 6-7feet high above and stairs that exit into our neighbours land. during lockdown we power washed and painted the deck and steps as it was unfit to walk on. We don’t use the deck usually but during lockdown our toddler played out a few times. It is our only means of escape downstairs and our deeds show it was some rickety old steps out to the yard before 2011. It also shows we have a joint right of way down this yard back up to the front which has been blocked and stone stairs completely removed. So in the event of a fire we have to try climb through bracken and brambles down a massive drop after we get into the yard. Our neighbour has suddenly taken offence at the painting and cleaning of the deck and steps and asked us to either alter it (to what we don’t know) or remove it completely or give her ownership of it all as she believes that a verbal agreement (which she agreed to in writing previously) Isn’t good enough as she now wants it changing. She’s bought the yard and house off the old owner and is annoyed about this verbal agreement now...was ok with it when it wasn’t painted like I say. Just some sensible fire regs advice please as I’m asking for legal advice too. I can attach deeds, photos of needed? thank you.
  23. Good Afternoon. I wonder if anyone can be of assistance. I purchased an Ei146RC smoke alarm to replace an older Ei146 which was emitting a persistent beep warning even after battery replacement. The unit had also passed it's end of life date. However I am unable to attach the new Ei146RC to the existing 12 year+ Ei146 base. Whilst it appears to mount as expected I am meeting firm resistance in the final couple of millimetres of horizontal travel and it won't fully lock into place. I've tried numerous times. I don't have this issue with the older Ei146. Should an Ei146RC be compatible with an older Ei146 base? Any suggestions would be much appreciated. For information both the old Ei146 and new Ei146RC connect successfully with the new Ei146RC base. But as this isn't attached to the ceiling or mains this doesn't resolve my issue. Thank you for your time.
  24. Hi we are in the process of purchasing a freehold flat with a UPVC kitchen door leading to the external fire escape. We are level 1 of 3 storeys. Is this legal? Many thanks
  25. Hi all, I've been grabbling with what to me is a tricky topic: the evacuation of people in wheelchair/ serious mobility disability from their domestic property, especially if they don't live on the ground floor. Plus some of them might live alone and not have anybody to help them out in case of a fire. I've searched the internet for an answer has to what evacuation plan should be advised to them. However, information on the topic have been sparse. Of course, those people should have fire warning detection and warning system at their home (e.g. smoke detectors, heat detectors...etc), but what if the fire happen at their home? What is the recommendation? Would there be a point to provide them with fire extinguishers and a fire blanket? The thing is that in most domestic buildings, there isn't necessarily what could classify as a refuge area. But would simply leave their house (if they physically can) and wait outside for the fire brigade be enough? The alternative is the installation of a fire suppression system (misting units), but I'm wary of those due to the potential of false trigger. But maybe that's the way to go? What is your opinion? Thank you all for your help.

    Only if the compartmentation between the restaurant and flat is inadequate, i.e. less than 60 minutes.
  27. I am wondering if anyone could help please. 1. Do replacement external windows on blocks of flats need to be fire rated? And does this differ from windows on standard house dwellings. The windows do not look out onto an external escape. 2. Do external windows on protected escape routes from blocks of flats need to be fire rated?
