  1. The common area is subject to The Regulatory Reform (Fire Safety) Order 2005 and requires a fire risk assessment. (FRA) You can do it yourself or use a fire risk assessor and choose one use A Guide to Choosing a Competent Fire Risk Assessor or if you decide to do it yourself the following guidance will help. For prices you will have to contact the suitable fire risk assessor. https://www.gov.uk/workplace-fire-safety-your-responsibilities https://www.gov.uk/government/publications/fire-safety-risk-assessment-5-step-checklist https://www.gov.uk/workplace-fire-safety-your-responsibilities/fire-risk-assessments
  2. I depends if it is a private seller or a business, private sellers are not subject to the legislation but businesses are. The enforcing authority is the Trading Standards so if it is a business then contact the local department. Fire safety of furniture and furnishings in the home - A Guide to the UK Regulations
  3. I would think the brass would not melt into a liquid form at those temperatures it is more likely to soften and distort like steel at those temperatures. Providing the door remains closed, the role of the lock will achieved its aims and it holds back the fire for the given time it will have passed.
  4. Door Widths (Where to measure)

    From the Home Office guidance Small and medium placesof assembly are the following statements. The effective usable width of an escape route is the narrowest point, normally a door or other restriction such as narrowing of a corridor due to fixtures and fittings. The capacity of an escape route is measured by the number of persons per minute that can pass through it so, to establish the capacity of the route, it is first necessary to measure the width of the route at the narrowest point. The effective width of a doorway is the clear unobstructed width through the doorway when the door is open at right angles to the frame. The effective width at any other point is the narrowest clear unobstructed width through which people can pass. When calculating the overall available escape route capacity for premises that have more than one way out, you should normally assume that the widest is not available because it has been compromised by fire. If doors or other exits leading to escape routes are too close to one another you should consider whether the fire could affect both at the same time. If that is the case, it may be necessary to discount them both from your calculation.
  5. BS9999 occupancy calculations

    I would use the guidance recommended by the Gov.UK DCLG Home Office. https://www.gov.uk/government/collections/fire-safety-law-and-guidance-documents-for-business.
  6. Plywood boards in riser cupboard

    There is no problem in using flammable material in the inside of a protected shaft, in most situation there will be, however if they are ignited then any fire should not be able to pass to the outside of the shaft and in this situation the brick wall will achieve that.
  7. To add to AB submission check out FIRE SAFETY Guidance on fire safety provisions for certain types of existing housing and A Guide to Choosing a Competent Fire Risk Assessor for further guidance.
  8. FRA

    How does a person get from outside to a room in the dead end, if the dead end leads nowhere. Check out Approved Document B (fire Safety) volume 2: Premises other than Dwelling Houses page 39 diagram 17 show what a dead end is.
  9. BS9999 occupancy calculations

    From what you say it is unlikely the buildings was built to BS 9999 so why are you using it for your calculations, it looks like cherry picking. Either way common sense would dictate the narrowest part of an escape route should be used to calculate maximum numbers in that escape route.
  10. FRA

    Why not, it is a single direction MoE and all the doors should be FR s/c to enable you to pass the rooms to get to a final exit door.
  11. Many years ago I was involved in double metal doors, fully glazed, with the intumescent seals concealed under phosphore bronze lippings, that met a two hour fire resistant standard. I think your door could be a fire door you need to check out the manufacturer. Check out https://www.iqglassuk.com/products/steel-framed-fire-rated-doors/s24176/ they are possible.
  12. You could check https://www.gov.uk/government/publications/operational-guidance-for-the-fire-and-rescue-authorities-incidents-in-tunnels-and-underground-structures appendix a Covers tunnels under contruction.
  13. Assuming you mean cease and not seize, then no it will always be CO2 while it is sealed in the cylinder.
  14. Common Areas in Flats

    Are there escape windows in accordance with Approved Document B (Fire Safety) in each habitable rooms and are the doors well fitting substantial doors to the escape route, check out page 46 of FIRE SAFETY Guidance on fire safety provisions for certain types of existing housing.
  15. Can we leave fire exit door open?

    Fire doors NO, if they remain open they will not function as required, final exit doors, that do not need to be fire doors, YES. It all depends also on what you means by retainer, if it is an electronic hold open device, then it could be acceptable on certain fire doors.
