Posted By shaun mckeever I have a building I am advising on. The building is listed. It has a single staircase and has 8 floors including ground and basement. Access to spaces off of the staircase is via single doors at each level. The doors are part of the listed status and do not provide any comparison to modern day fire doors. They are not fitted with intumescent strips or cold smoke seals. The building is multi-occupancy with the lower floors (B, G, 1 & 2) occupied by a single shop unit. The upper floors are multi-tenanted offices. The detection system will be an L1 system (not installed yet but soon will be). My problem is until recently a secondary means of escape was available via a roof and through a neighbouring property however this route is no longer available. There is no other secondary route available. Installing two door separation to the single staircase makes the building non viable due to the loss of lettable space. What are my options? I have considered pressurisation of the single staircase and upgrading of the doors but these create their own problems.

Posted By shaun mckeever I noticed my original post slipping down the list with no responses over the weekend. I know there are several good fire safety specialists out there and this issue has major implications if it is not resolved. I am also aware that there are several buildings similar to this, particlarly in crowded cities like London. So I am responding myself, partly to bring the subject to the top of the list again and also to encourage all you budding fire safety specialists to put your thinking caps on. Many thanks for your anticipated responses.

Posted By shaun mckeever Thanks for the advice. Talking to the fire brigade on an official basis will result in the building getting a prohibition notice served upon it. Also, from experience I find many fire officers will unlikely be able to identify a simple solution. In an example such as this the advice from the fire service would be to seek professional advice. The idea is to be able to approach the fire service and say yes I have a problem but I have a solution. In this way it is more likely that they will listen more sympathtically. Sadly this building had a fire risk assessment carried out by an RSP who did not identify the significance of the problem. I do find it concerning that some health and safety professionals are undertaking fire risk assessments where perhaps they should recognise their limitations. The prohibition notice would have been served on the basis that the threat to life from fire would have been so serious. I have identified a potential solution which involves upgrading the fire alarm to an L1, incoprating a water mist system in the accommodation spaces and ensuring that the doors are upgraded to provide 30 minutes fire resistance. Strict fire safety management of the building also forms part of the soluition. English Heritage were also consulted to ensure they were on board with the proposed solutions including the upgrading of the listed doors and the installation of the water mist system. Travel distances also had to be considered as the loss of the secondary means of escape effectively reduced the permitted travel distance. The Fire Authority have not yet been officially approached but off the record discussions have indicated the the solution is likely to be acceptable.

Posted By Stephen D. Clarke The document "Heritage under Fire" published by the Fire Protection Association ISBN 0 90216790-1 is quite useful and available on a CD as a pdf. I'd say if means of escape is physically limited in some way then you need smoke and other detectors etc in place to detect the fire sooner so people are warned sooner and so have more time to safely make their exit from the available means of escape.

Posted By Aidan Toner Shaun Yes, you are probobly right, RSP's may be taking on assessment work beyond their capability and this must be of concern.I myself have taken on fire assessment work and then struggled to recognise my limitations.Thankfully I did. All that withstanding-I would hope you are even more vexed about the design personnel who have permitted this particular situation to arise.You hav'nt commented on how the design process ended up here and how you have sought to re-engage the 'past design team' in the solution process.(Good luck on that one by the way) A cynic might think that you are connected closely to the design profession and tailor your wrath too neatly. I do hope you find a solution to your DESIGN problem.

Posted By shaun mckeever Aidan, the building was designed and constructed a couple of centuries ago. When the FPA came into force the building was found to require an alternative means of escape. Agreement was reached in 1971 for the escape route to be via the roof and a neighbouring property. The neighbouring property are no longer able to provide the alternative exit route. There is obviously no way of engaging with the previous design team. A cynic would be wrong in thinking I am closely connected with the design profession but might be right in assuming I am from a fire service background.

Posted By Frank Hallett Hi Shaun Do you want to discuss this directly? I've been in an essentially similar position not so long ago. Frank Hallett
