    Hi - I hope someone can assist. For a mobile home I assume it needs a BS5839Pt 6 fire alarm system. Does anyone know what grade and category it should be? Thanks for your help.
  2. Hi Tom - Thanks for your reply. Just as an update for the forum I looked at the following website in addition to the one Tom recommended. I appreciate many of you will already be aware of this. https://www.legislation.gov.uk/uksi/2010/2214/schedule/2/made There is an exemption from The Building Regulations 2010 - CLASS 3 - Greenhouses and agricultural buildings - See UK Statutory Instruments 2010 No. 2214 SCHEDULE 2. One of the exemption criteria is that the building is provided with a fire exit which is not more than 30 metres from any point in the building - my thoughts ar
  3. Hi, Can anyone please advise on the most suitable fire safety guidance for large glass houses which cover several hectares, typically for growing tomatoes, cucumbers and strawberries. Thanks
  4. I have looked at the white guide and knauff guide at MF fire rated ceilings and there is lots of info. However, I am trying to establish what fire resistance would be offered by a non fire rated 12.5mm plasterboard on a metal frame ceiling. The MF is plasterboarded is on the lower side only and there is no risk in the void above. I appreciate MF ceilings need various spacings for supports and hangers etc. The plasterboard has no markings for manufacture. Does anyone no where there is test data for such single sided plaster boarded ceilings of any thickness (with 3mm skim). Clearly it wi
  5. You may want to consider the Lacors Guide: https://www.rla.org.uk/docs/LACORSFSguideApril62009.PDF See Page 18 Para - 15.5 Gas or electric meters and/or distribution boards should ideally not be sited in escape routes. However, it should be possible to relax this providing any gas meter is installed in accordance with the gas safety regulations and any electric meter is installed and sited in accordance with current IEE regulations. It is considered best practice to enclose such equipment in fire-resisting construction.
  6. Hi Tom Thanks for your reply, I have found some useful guidance in BS9999. If any one needs it please look at Annex F (normative) Process plant and outdoor structures on Page 355.
  7. Hi, to assist in completing a fire risk assessment can anyone offer guidance on the most suitable documents for assessing multi storey external plant with open grid stairways and walkways etc. These are open to the elements. The CLG suite of documents has fire safety risk assessments: factories and warehouses, but are there more relevant guidance documents which I can research and apply?? Thanks

    Hi, I did get a little lost with my lack of understanding on these units. I hope you don't mind if I raise a query on the topic of magnetic locks. They are frequently used in residential home on final exits and to segregate areas IE residents with different mental capacity, limit access to stairways etc. If the magnetic locks fail to the open: on operation of the fire alarm, on failure/fault of the fire alarm, on electrical power failure, and on operation of a key pad Then why are manual green overrides necessary? Staff assist all residents and visito
  9. Hi Tom The research established that there are a myriad of different plasterboards, thicknesses and manufacturers. For the FR on some it depends on roof truss spacing, nogging & nail spacing etc etc. Whilst the aim was to determine the rating of existing ceilings below roof voids without flooring above I didn't achieve that. On some you can see the boarding is pink and can google data printed on the boarding to further the research. As part of my research I contacted various manufacturers who simply refer to there guidance docs/ data but you can't always ID who manufactured the b
  10. Thanks Guys i will try to source copies of the BRE documents.
  11. Hi Tom - thanks for your replies. The thread has not had much activity so far. I have looked at the information and links & the Rock wool flexi guide offers other ways for a 30 min ceiling/floor beyond the British Gypsum White Book. On one of the threads a person mentions standard 12.5mm plasterboard single sided offering 15 to 20 minutes fire resistance - does anyone have any evidence of this??? I telephoned British Gypsum Technical helpline today but they can only offer solutions from the White Book. Does anyone have any evidence of what a ceiling offers in terms of fire resista
  12. Hi All I wonder if you can assist. On the top floor in a care home the ceiling is 12.5mm plasterboard fixed to roof trusses not less than 38mm thick. The plasterboard is skimmed and there is about 150mm of rockwool above. This arrangement covers the top floor bedrooms, escape corridor and elec room, sluice room, clinic room and lounge etc. The roof void above the protected area of 10 beds has cavity barriers and is free of storage. The concern is the escape corridor and risk rooms may not give 30 mins fire resistance at ceiling level. The plasterboard is not fire rated and a fi
  13. Hi Anthony B - thanks for your reply. I looked in the DCLG resi care guide but did not find much other than : Page 94: - Means of escape – security It is accepted that in many care home situations conflicts between the needs for means of escape and security may arise, particularly in premises which provide accommodation for people with mental illness, where it may be essential to maintain a high level of supervision during an evacuation. In areas where security is important a properly designed and managed interface between staffing levels, installed fire safety meas
  14. Hi Tom Thanks for your prompt reply and logical thought process.
  15. Hi All In a residential care home with electro magnetic locks can you advise on the following. The home has areas with people who have mental health issues. As such these wings are secure and staff and visitors enter via key pads - entering the numbers. The locks fail to the open on power failure and on operation of the fire alarm system. To escape staff can aid residents out. I have noticed some homes also have green break glass overrides adjacent to the door as well. Are these additional overrides really necessary? Thanks
