The relaxation only applies where: a. The top storey of the building is a maximum of 11m above ground level. b. No more than three storeys are above the ground storey. c. The stair does not connect to a covered car park, unless the car park is open sided d. The stair does not serve offices, stores or other ancillary accommodation. If it does, they should be separated from the stair by a protected lobby or protected corridor (minimum REI 30) with a minimum 0.4m2 of permanent ventilation, or be protected from the ingress of smoke by a mechanical smoke control system. e. Either of the following is provided for the fire and rescue service. i. A high-level openable vent with a free area of at least 1m2 at each storey. ii. A single openable vent with a free area of at least 1m2 at the head of the stair, operable remotely at the fire and rescue service access level.

Hi, This is a UK site so can't advise on OSHA issues - although do note that in our guidance we use 'tap' where the US guides would say 'faucet' and a funnel is not a tap. I'm not sure how prescriptive your codes are but here if you could demonstrate that your solution provided equal or greater safety than that in the guidance it would be accepted by our equivalent of OSHA

If they are 1980's then unless they are very late 1980's they are unlikely to be legal and would have coverings and foam that would fail the fire tests as the change in law on furniture wasn't passed until 1988.

Usually a complete tested & certified doorset (i.e. door & frame) is required - as it has to be an FD30S door it will also need intumescent strips with cold smoke seals as well.

No, they don't: C5 All fire doorsets, including to flat entrances and between a dwellinghouse and an integral garage, should be fitted with a self-closing device, except for all of the following. a. Fire doorsets to cupboards. b. Fire doorsets to service ducts normally locked shut. c. Fire doorsets within flats and dwellinghouses.

Have you paid them? Sounds like they have bodged it and messed up your doors! Perko's (other than one specific modeI) have been non compliant for a very long time, the gaps are a bit on the large side (unless the manufacturer has a certificate saying it passes with larger gaps than normal) Is it rail/side joint or rail/style joint - see this picture as the latter makes more sense:

Not unless tested and passed as a complete doorset of door and frame - it would be unusual if it could pass this way as the rebate only method went out with the Ark as they were proven to be completely useless! You see 25mm rebates on old legacy doors from before the existence of intumescent strips, but you wouldn't usually see it now - remember it has been in some guidance that to get the FD20 rating for internal dwelling doors you could use an FD30 doorset but not fit the strips, implying a reduction in performance.

You've posted this in one than more section - see the replies there.

From Building Regulations Door fastenings 3.91 In general, doors on escape routes (whether or not the doors are fire doorsets) should be either of the following. a. Not fitted with a lock, latch or bolt fastenings. b. Fitted only with simple fastenings that are all of the following i. Easy to operate; it should be apparent how to undo the fastening. ii. Operable from the side approached by people escaping. iii. Operable without a key. iv. Operable without requiring people to manipulate more than one mechanism. Doors may be fitted with hardware to allow them to be locked when rooms are empty. If a secure door is operated by code or combination keypad, swipe or proximity card, biometric data, etc., a security mechanism override should be possible from the side approached by people escaping. 3.92 Electrically powered locks should return to the unlocked position in all of the following situations. a. If the fire detection and alarm system operates. b. If there is loss of power or system error. c. If the security mechanism override is activated. Security mechanism overrides for electrically powered locks should be a Type A call point, as described in BS 7273-4. The call point should be positioned on the side approached by people escaping. If the door provides escape in either direction, a call point should be installed on both sides of the door. That's as specific as it gets.

If your exit route is vis the garage it's preferable (not mandatory if not practical). If not, then as long as it's a fire door it should be fine whichever way..

Whilst outward opening doors are preferred, they are only mandatory for exit routes likely to be used by more than 60 persons. From Section 3.94 of the current Building Regulations for dwellings (my italics): Direction of opening 3.94 The door of any doorway or exit should be hung to open in the direction of escape whenever reasonably practicable. It should always be hung to open in the direction of escape if more than 60 people might be expected to use it during a fire. As it's not used by the mandatory numbers and appears to affect the utility of the door its arguably not reasonably practicable to hang outwards.

If they are kept locked shut and signed as such then they are excused self closers. If they are in such regular use or a use where locking is impractical (too many different people need access, such as a riser cupboard with a dozen flat's meters in) then a self closer may be more appropriate.

The 2005 Fire Safety Order explicitly excludes dwellings and only covers parts in common such as the external wall in your property. If they are an owner occupier fire safety is solely their problem. As long as your renovation complied with Building Regulations (or if outside the scope of where approval is needed didn't make the original provisions worse) you are fine.

Yes, especially as they don't from your description appear to be approved for fire doors. The integrity of the door could be affected, also depending on the situation the door might not meet exit fastening standards.

If it's small and only is likely to contain less than 60 persons then the normal entrance alone may suffice. Your Fire Risk Assessment (which you are legally obliged to complete) would determine this applying the benchmarks in this document: https://www.gov.uk/government/publications/fire-safety-risk-assessment-offices-and-shops

No, the "mains on" LED is an integral part of the fittings. I have heard anecdotally some of the downlighter versions can have it disabled but can't confirm this. It's up to the Responsible Person to decide if they want to obscure this as they are legally liable - it has been argued that as long as the required monthly and annual testing regime is in place this would suffice - some places have increased the function testing to weekly as mitigation. Any deviation would need to be justified in the premises Fire Risk Assessment as to why it doesn't prejudice the safety of relevant persons.

It would have been Approved Document B as it has been since 1991 - the 2000 edition would apply. Past editions are here https://www.planningportal.co.uk/applications/building-control-applications/building-control/approved-documents/part-b-fire-safety/previous-editions

It was not unusual in the past for multiple extinguishers to be used on fires almost in a bucket chain of them - and one major manufacturer from the 20th Century advertised how a use could refill their extinguishers in 30 - 60 seconds max to allow a continued attack on the fire. Works brigades or works fire teams were not uncommon and many fires were extinguished or controlled this way with anything from one to a dozen extinguishers used. Society is far more risk averse these days hence the approach you are hearing. However that doesn't stop you deciding to do what you feel best and have the kit for a prolonged attack as long as you don't put yourself in danger by following basic fire fighting practice (e.g. stay low, keep a exit behind you, etc)

By definition a Grade D alarm is powered by a 240V supply, the 1 or 2 defining if the back up supply also required to each alarm is a sealed tamperproof battery/cell or a user replaceable battery. If you only have the built in power supply and no mains then it is only a grade F alarm (which can only be used in a rapidly decreasing number of situations) being a F1 or F2 again depending if the (sole) power is from a sealed tamperproof battery/cell or a user replaceable battery.

Is this an external gate not in the actual building? Does sound rather OTT and not covered explicitly by an actual regulation.

As a conversion from a house they are likely correct - see my detailed answer in this thread:

That's really one for your fire risk assessment however from the guidance for Specialised Housing it says: The extent of automatic fire detection should comply with the recommendations of BS 5839-6 for a Category LD1 system (which is the highest category for protection of life in domestic premises). Smoke detectors should be provided in all circulation spaces, and in all rooms within the property, other than kitchens, toilets, shower rooms and bathrooms. In kitchens, heat detection should be provided. However, where a kitchen or dining room forms an inner room accessed only from the lounge, the detector in the inner room may be omitted (rendering the system Category as LD2). No fire detection need be provided in toilets, shower rooms and bathrooms or, normally, in cupboards. There will normally be no need for fire detection within roof voids, unless there are specific, significant fire hazards within a roof void, such as gas boilers or electrical equipment for photovoltaic systems. All smoke detectors within circulation spaces, or areas into which kitchens open, should be of the optical type; alternatively, appropriate multi-sensor detectors may be used. In single storey premises and other premises with no more than four bedrooms (including staff bedrooms), fire detection may comprise a Grade D system, as defined in BS 5839-6: 2013 (i.e. the detectors may comprise mains-operated domestic smoke alarms with internal standby batteries or capacitors). All smoke alarms should be interlinked by either wiring or radio transmission, so that, when fire is detected by one smoke alarm, all smoke alarms in the property sound simultaneously. Unless there isat least one member of staff present (whether awake or asleep) on a 24-hour basis, the standby batteries should be tamper proof (e.g. cells soldered to a printed circuit board, capacitors or PP3-type batteries that are fixed in place and cannot readily be removed). In premises of two or more storeys with more than four bedrooms (including staff bedrooms), domestic smoke alarms should not normally be regarded as adequate. The fire detection in these premises should comprise a Grade A system, as defined in BS 5839-6, with control and indicating equipment sited within the ground floor circulation space, fire detectors and fire alarm sounders. Where there is, at any time, less than two members of staff on duty, either the system should be addressable or there should be remote indicator lamps outside the entrance door to each resident’s accommodation, so that the location of a fire can be quickly identified. However, if existing premises of not more than two storeys are provided with sufficient mains-operated smoke alarms (with standby batteries or capacitors), these need not be replaced with a Grade A system until the smoke alarms reach the end of their useful life.

Bathrooms, unless containing a higher risk (e.g. boiler) don't usually require a fire door

Depending on who will be using the door (staff/public, under/over 60 persons) you should use either a BSEN 179 emergency exit device (https://www.safelincs.co.uk/emergency-bolts-and-push-pads/) or BSEN 1125 panic exit device (https://www.safelincs.co.uk/panic-bars-with-latches-or-bolts/)
