Posted By edmund barker We have 2 fire exits -1 double door and 1 single door.They are only approximately 5 feet apart can we make the single door an ordinary exit door? The double door allows for maximum escape and is in good working order and serviced regularly. If it can be changed, apart from the fire risk assesssment is there any other authority that requires notification?

Posted By SBH I suggest you have a look at approved document B that will give you plenty of info. eg widths, occupancy levels etc. SBH

Posted By marcusblack Hi, Any material changes to a fire exit will require building control approval. Cheers, Mark

Posted By Toe Dependant on the room dimensions, because the doors are so close together, it is generally deemed that both doors are classed as only one means of escape i.e. one is not an alternative escape for the other. Therefore I think that you can make the single door an ordinary exit door as long as it is still kept as a fire door (auto door closure, smoke seals etc.)

Posted By Messy Shaw Toe - If both the doors are next to each other (separated by 5') it is very unlikely one would be an alternative for the other. Also, you mention that the final exit door will need a self closer and smoke seal. Most final exit doors need either. Self closers might be needed if the final exit door discharges close to, or under an externals escape staircase to protect occupants using those stairs. I don't wish to be rude here, as I know that everyone who posts here does so freely and with the intent of helping others, but I really do believe if you are not 94.5% sure of the advice you are giving, perhaps you shouldn't give it at all.

Posted By martinw FFs what of the situation where you have double doors side by side meeting together in the middle, forming seperation from a lobby, to a corridor containing the front doors of flats: the smoke brushes are on the door frame and none are on the doors themselves. The doors have no intumescent strips. Where the doors meet in the middle - where the static push handles are, not the hinge sides etc - there are no strips or brushes between the two timber surfaces of the two doors. Therefore there is no barrier to smoke. I must be having a brainstorm, but I am embarrassed to say that I cannot find the justification to tut at this. I know the British Standards which are relevant but this is so specific that I cannot find the right wording for the justification to shoot it down. Any ideas? I know the normal 'every door should be fitted with brushes....' standard quote but I cannot find the specific reference. In the same set of flats I found two fire doors side by side as above, forming side by side barriers, meeting in the middle at the end of a corridor. One has an integral intumescent strip, the other door forming the fire barrier had a smoke brush. I know that this sounds bizarre but the same situation is as above - this is clearly wrong to me(looks as if the builder ran out of right and left hanging fire doors which matched) but I cannot pin down the exact justification for recommending change. I appreciate that if this is a stupid question which is obvious to you guys, you may smirk, but I am happy to ask when I do not know. Can you help? thanks and sorry for hijacking but this is on a similar tack... Martin

Posted By martinw Two doors, side by side, forming one end of the corridor. Would be easier if I could copy and paste pics but not to be.

Posted By Toe Messy Please can you explain where in my comment or the original post that it states the fire exit is a final exit, please read the post's carefully. My advice that is given is from the Approved Document B from the Building Regulations 2000/2002 (design for horizontal escape buildings other than dwellings) the document being sanctioned by the Office of Deputy Prime Minister. Whereas if it it not possible to have alternative routes separated form each other less that 45o then the maximum distance for a single route apply. In essence my advice is that one of the doors could be used as an ordinary exit because it may not be deemed as a means of escape i.e the other door becomes the fire exit. I don't wish to be rude here, as I know that everyone who posts here does so freely and with the intent of helping others, but I really do believe if you are not 94.5% sure of what you read, perhaps you shouldnt comment at all.

Posted By martinw This forum can be a pain sometimes. It gives me great info and assistance, yet sometimes due to the fact that it is written word, nuances have to be inferred, and therefore meanings sometimes have to be also rendered. I have found that my style has been misinterpreted in the past to be very confrontational and due to that I now have to consider how I write posts to make sure that I primarily get my meanings across, but also that I come across in the way I meant to. It is not easy. I have re-read posts about which I have pressed the send button a number of times after being required for an explanation and sometimes it is my fault for not thinking it through, sometimes it is the other person not reading it properly. We all make mistakes.... Not trying to stick up for anyone or fight any battles for anyone. We are all big enough to stand up for ourselves. But it is very easy to be misinterpreted and in doing so, such misinterpretation does not always require an explanation, nor should it. D Hilton - my pics are not available as my remote work PC availability is down. Will send tomorrow. All the best.

Posted By Toe Martinw, It may be that the doors met with the relevant building regulations at the time the building was constructed. As the regulations change throughout the years it may be the case that these doors may not meet today's building standards, which does not necessarily mean that is is wrong. However a comprehensive fire risk assessment should identify that the building may be able to be changed/modified to meet some of today's current building standards, again not a legal requirement to ensure that all buildings (except new builds) meet current standards but this would be good practice AFARP. Messy, Apologies accepted

Posted By martinw Appreciated Toe. However the building was constructed in 2007. Those building regs apply. It still has three flats unsold. Having heard about this a few weeks back, and having been told to leave it alone, I am still chasing the folks who installed and commissioned the fire alarm, and information about what grade and coverage is involved. I think that I know but am no fire engineer and require verification for that reason. The final side by side exit doors to one of the three blocks open inwards, and one of those two doors has to be locked to allow full security otherwise when both are unlocked, the maglocks are not strong enough to stop access from the outside by mere pushing. Obvious implications... I hopefully will get information from the commissioning fire panel/system engineer tomorrow. If it is interesting then I will be more forthcoming. Either way I will be presenting my findings in person to the local fire safety officer.
