Best solution is to fit floor springs and pivots. See page 39 of the document Hardware for Fire & Escape Doors - Code of practice http://firecode.org.uk/Code_of_Practice_hardware_for_fire_and_escape_doors.pdf

That's useful to know, Anthony. Do you have link (and page/section number) to the gov guidance document?

From what you say it seems clear that area of the house could be at risk from the effects of a fire in the garage. I would consult the housing department at your local authority on this matter.

Yes the entrance door to your flat should be fire resisting and with restricted cold smoke spread.

Its actually BS 7352 Grade 8 dating back from the 1990s. In those days, prior to its replacement BS EN 1935 2002, that type of hinge would have been used for Fire Doors. If the hinge is damaged or worn then replace all hinges on that door with their modern equivalent to BS EN 1935 minimum Grade 11

I have inspected many fire doors to stair and lift lobbies at blocks of flats. Some older blocks have doors without vision panels but clearly a door in such a location is safer for the user when there's a vision panel.

The main issue is that a standard intumescent air transfer grille will not restrict the spread of cold smoke. Also, installation of such a device should be done by a competent person so as to ensure the door's fire integrity performance is not compromised. If the door in question opens on to an escape route, there is a risk that cold smoke from inside (in a fire event) may impede persons attempting to use the escape route. Your fire risk assessment should note this and recommend action accordingly.

In my view, the mirror is rather large and heavy. I would not recommend fitting such a mirror to a fire door due to risk of causing twist to the timber door leaf. Much better on the wall or maybe a wardrobe, if possible.

What size are the screws? Where on the door are you fitting the mirror (will it be near the door edges) and how big and how heavy is it? What have the block owners/mangers said about this?

My understanding is that the doors are FD30s fire resisting doors. Are the rack bolts compliant with paragraphs 6.2.2 and 6.2.3 on page 61 of the document 'Hardware for Fire & Escape Doors' ?

So the door will be a FIRE DOOR KEEP LOCKED and kept locked at all times. The door should be fitted with a fire rated mortice lock and a 'Fire Door Keep Locked' sign to the outside. I assume the door is made from timber based materials. The document 'Hardware for Fire & Escape Doors' at http://firecode.org.uk/Code_of_Practice_hardware_for_fire_and_escape_doors.pdf provides the information you need on pages 60 to 68.

Looking at this from the fire door survey point of view. The British Standard for timber-based fire door assemblies (BS 8214) states no requirement with regard to floor coverings at the threshold. Installing a threshold strip to the floor is always preferable as it helps meet compliance with door leaf to floor gap requirements. BS 8214 and BS 9999 refer.

The requirement in terms of threshold gap for a timber based fire door is 3mm max where the door also provides restricted smoke spread. Where restricted smoke spread is not a requirement the max gap is nominally 10mm (sometimes less depending on test evidence). More than 100 is a lot of fire doors (for an industrial premises) so one would ask whether they all really need to provide fire and smoke separation? The building operator should have carried out a fire risk assessment and should carry our periodic fire evacuation drills. From having conducted those a fire strategy document s
