It is always preferable to lip the bottom of a door as in a fire the most sever conditions can usually be found at the top opposite the hinges, this is one of the reasons why the certification mark is put here. If you do lip the top of a make sure you take images of the certification before you modify the door.

Technically adding a decretive moulding to the door should not be a problem. You need the global assessment for the door so that you use the correct moulding in the correct position and adhesive.

As a general rule flat entrance doors should be fire rated. The basic exception are when there is no door or window above them (top floor) and a person can get 1.8m away from the building without passing another door (a balcony for instance)

The fact that the lipping on both leaves appear to be the same would suggest to me that that this was how the doors where manufactured. The door we can see through the vision panel, does it have the same band at the head? and what about the bottom of the doors?

Given the fact that these doors contain Georgian wire, I suspect that they do not conform to the latest standards, however, unless there is a fault or defect with the door, they will do a job. I would suggest you mark them down as nominal fire doors and leave it up to the building owner as to if the wish to replace the door. There is no expectation to replace something under Approved Document B unless there is a material alteration to the building

All depends on what it is protecting. If there is no smoke requirement then I would say that steel door would offer greater protection than a wooden door.

If this is the only sign, then it does not satisfy the RRO. Fire action notice signs should be designed to clearly people with various instructions to make during a fire, including how to raise the alarm and where the closest assembly point is.

This is a building management issue not a fire issue

I would be more concerned about the possibility of asbestos

You could always try automated fire shutters

You can use a “similar repair technique” you just can not claim it is TRADA approved repair

Look at building regs, doc B, 2019. Table C1 11 b. The doors should be FD20, which are no longer available, so you need a FD30. There is no smoke requirement. There should be intumescent, have you checked they are not in the frame

I would have expected that the glazing was compliant with the regulations at the time of installation. There is no requirement to bring the glazing up to date unless it is defective. BR stipulates no worse than existing.

If there are >59 people expected to use the door in a fire condition, then the door must swing in both directions. otherwise as long as the global assessment for the door allows it and the person carrying out the modification is competent then yes

I would ask the requester what type of fire door inspection certificate they require, been well versed is completely different to having passed a course. The inspection scheme may fail a door because it is not up to the current standard but there might be nothing wrong with the entire installation and over all fire measures throughout the building. I am sure that doors in Buck house would not pass a full inspection, but would you replace them all?

So your client want an inspection to a 3rd party accredited scheme, but is unwilling to allow the scheme to review the reports in order to verify your results. Seems to be a bit of a contradiction

Can the door be lipped?

The 2-4 gap quoted refers to the installation of the door, any deviation from this over time would be risk based in line with the RRO. If you are happy with a 5 mm gap and are confident that you can convince a man in a curly wig, then yes

We have had a problem of a facility manager lubricating the hinges to stop the doors creaking. Clean off the hinge and monitor. If the oil returns, change all hinges on the door as if one has failed the others won't be far behind.

Neither, they should have "Automatic Fire Door" signs

Pads are acceptable if <= 60 people are expected to use the exit AND they are familiar with the building

All depends on the size of the shop and what it is selling

Approved Document B 2007 Appendix B Paragraph 9 The following fire doors are not required to comply with paragraph 8 a. Doors to and within flats b. Bedroom doors in other residential premises c. Lift entrance/landing doors
