  1. 1.  Brad today it’s all about risk assessment so what are the chances of a fire on the premises, the electric supply and external lighting failing at the same time, I would think pretty low consequently an acceptable risk.

    2.  If you are accepting borrowed light as acceptable, then you do not require emergency escape lighting therefore photometric data is not necessary.  I would conduct an inspection during the hours of darkness, switch off the lights, if I can find my way about and see what I need see, then emergency lighting is not needed. I accept it cannot be done off plan.

  2. There needs to be a permanent label on each separate  item of the sofa and if one has come loose then there isn't much you can do about it especially if it it 15 years old. Records only have to be held for five years, so there is no chance of getting a copy, but if you are happy with it then the only problem to arise, is if you decide to sell it or give it to a charity.

  3. Check out what it says in Fire safety in purpose-built blocks of flats, and then be clear in your report what it is you are, and aren't including in your assessment. You can only survey what you see without destroying the fabric of the building and make it clear that the survey is not intrusive and if they want otherwise this would entail potentially a lot of damage throughout. You can check service shafts and certainly the bottom of service shafts where pipework and cabling enter/exit, also check above suspended ceiling, however this would mean carrying step ladder/torch. As the assessment is purely non-destructive and as AB says it all depends on your findings what you think it reasonable to recommend a follow-up compartmentation survey.

  4. The standard for the legend on fire exit signs are BS EN ISO 7010 and is acceptable for British and EU regulations but if illuminated fire exit signs are required they must be combined with emergency escape lighting and as the electric supply will be available then LED illuminated signs would be a better option considering the price of self-luminous (tritium) exit signs.

  5. You do not say where the premises are I will assume it is in England or Wales.

    What you propose is a material alteration and will be subject to the Building Regulations which uses Approved Document B (fire safety) volume 1: Dwellinghouses as one of its guidance documents. Your proposal is creating an inner room situation which is only acceptable where the inner room has access to a emergency egress window which is not acceptable above 4.5 m and your new study would be above 4.5 m above the ground. I would suggest you contact your local building control and outline your proposals to them.

  6. You say "She works alone as a sort of general assistant (cleaning, doing odd-jobs), so she is not often in classrooms" how many different location is she likely to be alone?

    People who are deaf and hard of hearing should be taken into account in the design of fire alarm systems and evacuation management plans. The use of flashing beacons, vibrating pagers or pillows, and similar alert devices should be considered, appropriately located and backed up by an integrated fire management plan. Where an individual PEEP can be produced, the use of a buddy system should be considered. 

    Have you considered a PEEP and buddy system?

     

  7. Smoke detectors in all habitable rooms will not stop a fire spreading so you may still require fire doors. As to the amount you can trim off a fire door will depend on the construction and the thickness of the lippings so you will need to contact the retailer or manufacturer to establish the amount that it is safe to remove, it could be 6mm or more.

  8. If the shared corridor is a protected route then all the doors will be FD30s doors, self closing and if you prop these doors open then it is certainly against the regulations. There should be a mandatory, white lettering on a blue circle sign stating "FIRE DOOR KEEP SHUT" and it is not there to decorate the door.

  9. You need to get together with the fire risk assessor and a fire alarm designer to design the system you require for example what categories do you require. Do you require only a manual system (M) or combined with life system (L) or including a property protection system (P) to costs will vary considerably.

    For example Offices: 3 Floored Victorian Building

    12 x Optical Smoke Detectors
    2 x Heat Detectors
    7 x Manual Call Points
    5 x Sounders

    Alarm System Used: Apollo non addressable

    Supplied, fitted, commissioned and certificated £4644 plus Vat

    Once you you know what is required then you can get some estimates.
