  1. If the flats have no fire alarm you could consider cam action doors closer which is extremely efficient, allowing the closer to be set to provide reliable closing power for fire door applications yet still be easy to open.
  2. You only require to update if there has been a material alteration that has made the means of escape worse.
  3. Why? but if you do need an alternative fire escape route, escape through the garage could be acceptable, but the two routes would have to be separated by a minimum 30 mins fire resistance.

    BS 9999

    There is a few libraries throughout the country that give free access to BSI online, but it must be viewed in the library premises. Most universities give free access to their students and you can take out BSI membership, at a cost, and get standards half price. Other than that it's an expensive game.

    Intumescent strips and smoke seals

    In the 60/70s the only door I remember had cold smoke seals was, smoke stop across corridor doors, used to divide up long protected corridors, into 60 feet maximum length.

    Antique Reupolstered Settee

    The regulations are concerned with the upholstery not the frame and although the frame may be pre 1950 the upholstery is not. If it was reupholstered in the late 80s early 90s then the who ever upholstered it is subject to the regulations and should have attached the appropriate labels to comply with the regulations. Consequently if it carries the appropriate labels no problem, if not, you could have problems if you try to sell it, and I think you would be outside the law.

    Sprinkler system in school toilets

    It does appear that many schools fitted with fire sprinklers do extend them into toilets and there has been fires extinguished by them. However this would be up to the sprinkler design engineer to decide the layout and if they are required in toilets. https://shop.bsigroup.com/ProductDetail/?pid=000000000030337104

    CO2 fire extinguisher pressure

    As far as I can see it depends on the temperature of the room, if you study the links above I am sure you will find the answer.

    Fire escape windows

    You do not require an escape window if you have a protected escape route (protected staircase enclosure) to outside the premises. As for the size I cannot help you there check with planning or building control.

    Open Roof Voids

    I think it is sufficient to know that fire will spread upwards, sidewards and downwards, fastest upwards, slower sidewards, even slower downwards but will spread in all directions depending on the construction. If you want a more scientific approach then google "research on downwards spread of fire" I am sure someone will have researched it. For a new flats development, an architect would use ADB or BS 9991 or an engineered solution, I know ADB or BS 9991 requires 60 mins separation between every dwelling which I think would not be achieved by a double layer of plasterboard, but I would need to research that.

    Intumescent air transfer blocks

    First of all what type of fire door are we discussing a FD30 or FD30s fire door. If it is a FD30 door then intumescent air transfer grill could be acceptable and to do what you suggest I would contact the manufacturer to obtain their advice.

    Will fire rated pocket door meet regulations

    It looks like the staircase is open to the dining room which would not be acceptable, again a proper drawing is required and I would not try to give any suggestions without it.

    Will fire rated pocket door meet regulations

    I cannot make sense of the drawing, you need a proper architects drawing with measurements and what is half hour fire resistant.

    Fire stop training

    I cannot see why not the fire inspector will take the responsibility and I suspect he/she will be calling you back if you do not get it right.
  15. No requirement for full 30-minute protected route all doors should be FD20 fire doors. However well fitting sound conventional doors/construction are acceptable, also the travel distance should not be excessive. All except the door to the internal garage, which remains a garage until you convert it to a habitable room, should have full FD30s fire door and be fitted with a approved self closer.

    Height of fire exit sign

    If the sign is indicating to use this door, it sounds you do not have an option however I would ensure the upwards point arrow is next to the door, next to the pictogram, next to the lettering.

    Riser/service cupboards fire protection

    All through the fire safety legislation it emphasizes the need to be a competent person and if you are not, then you could be in trouble but if you wish to consider installing fire stopping products then become a competent person. It's a matter of training and self study, I would start with http://asfp.org.uk/ and check out their publications.

    Fire Alarm Sounder Tests

    All sounders should be tested weekly on the weekly test and 12 month period, if any occupant doesn't hear the alarm or has difficulty in hearing the alarm should report it, the management/service engineer who should then investigate it. I cannot see how a two person team could test the sounders without a great degree of disruption with the sound continually going off.

    Fire exit windows with locks?

    If you have a lock with a removable key then it should be available for use if required, mine I keep in the lock. I would imagine the height is based on what is considered a high window cill (bathroom for instant) but once set, do you allow a tolerance, which ADB doesn't, then it is left up to the enforcing officer and some, I am afraid, are code huggers.

    Height of buildings

    They are arbitrary figures and if you convert them to floors less than 18m is about 6 floors reaching about halfway up the 7 Floor, above 18 m will be 8 floor so dealing with fractions of a metre is not called for. Also fighting a fire in an a building eight storeys or more, has to be fought from inside the building, because the availability of ariel appliances and their capability are limited and I believe the extra protection is needed.

    Electronic lock

    This is a security problem check it out with a security firm/forum and I am sure they will be able suggest suitable doors which will also meet fire safety standards.

    Guest bedroom leading off kitchen/diner

    This sounds like an inner room situation and is not acceptable in Approved Document B (fire Safety) volume 2: Premises other than Dwelling Houses see page 21, 34, and 36 also check out the index.

    Break in intumescent seal at door lock?

    It should be acceptable if you fit intumescent pads on the lock and hinges see the following video https://www.labc.co.uk/news/how-to-install-fire-door-properly. If you have to satisfy an enforcement office check with them first.

    Fire Door

    If the curtain interferes with the opening of the fire door then it is not acceptable and your fire risk assessment is likely to have it removed.
