Without a site survey or detailed plans it would be difficult to say and I think the services of a competent fire risk assessor is required.

As I have said the lift is in a 30 min protected shaft so how will the fire pass from floor to floor, I do accept the smoke problem but modern lift seems to have solve that one.

What material is the duct constructed of, and why do you think it may need fire sealing.

If the cabling is outdoors under the rooftop, of the house I suspect the eves, where is the fire risk?

Enforcement officers accept labels fixed to the interior pads of scatter cushions and suggest that the label protrudes through a partly open zip at the point of sale so it is visible.  Fire safety of furniture and furnishings in the home A Guide to the UK Regulations  check out page 29 A4.1.

What is the problem if the lift is in a protected shaft?

Not all exits needs to be signed but what you have stated, appear to be correct and in the case of a fire this door needs to be available and it may, without an inspection it is impossible to say.

No, what would be the fire risk?

The front exit is your principle means of escape (MoE) the rear exit is your alterative MoE so if you have to exit your premises then you use the front door and only if that is impassable do you use the rear exit. Assuming the MoE is of a high standard only one MoE will be affected in the event of a fire in your building so you will always have a means of escape available. The standard of the means of escape is a matter for the Responsible Person (owner, landlord or yourself) and without a survey I am unable to give a categoric reply.

Not a very good fire risk assessor then.

This question should be transferred to Fire Doors and Accessories.

 

Fire safety legislation does not give prescript requirements it simply gives requirements that needs to be achieved like, measures to reduce the risk of fire on the premises and the risk of the spread of fire on the premises, how you can achieve it is left to the guides and codes.

The insurance company is more concerned with property protection and they can lay down conditions they think necessary. If you require their insurance you have to abide by the conditions or negotiate for a more favourable situation.

 

Sorry about my faux pas, back in the sixties it was common to see this, but I do agree it is wrong, because if the door is open, you most likely to be unable to see the sign. 

Can you post an image of the doors in question.

Without a survey it is impossible to say what MoE is required, it all depends on the layout of the premises. 

Does the inner room meet the necessary requirements without the escape window?

All doors in a single domestic dwelling should be FD20 fire doors and because FD20 fire doors are not usually available they will need to be FD30 fire doors however self closers not required.

Filling small holes use intumescent filler and fire doors in single domestic dwellings are not required except if you have one giving access to an attached garage.

You need to check the manufacturers instructions that came with the fire doors.

Use a standard FIRE EXIT sign with upwards arrow and fix to the door itself.

There are two fire labels on a upholstered item of furniture the permanent one and display label which are you talking about.

Everybody who may use the staircase should have access to a switch, to light up the staircase, also the main light power supply may fail so a emergency lighting system should also be available.

Where is the main switches for the main light located, the emergency lights will only come on if the power supply to the main light fails.

I do not understand your question the 3mm gap is the gap when the doors are installed?

You need a more clearer description with sketches and photos It is difficult to understand what you are proposing.
