Davey,
I hope that this hasn't reached you too late, I have had a bit of a palava getting registered on this board.
As has already been mentioned the safety law/standards are a bit of a mix. For strategy purposes and building layout they stick to NFPA (particularly 101 and 5000) but with some BS for things like AFD. Sprinklers are to NFPA 13. I have a bit of paper given to me by Civil Defence (treasure anything that is physically given to you by CD they so rarely give you anyting in writing) which lists the standards they require. Having said that I don't seem to have it with me at the moment but if you require what is on it I will get it and give you the information.
There are rumours that there will be an Emirates wide Fire Code which, I think, Locke Carey are helping with.
You are lucky to be dealing with Dubai CD. They are well organised and generally very helpful and put the Civil in Civil Defence. Most of my work here is in Abu Dhabi where things are very different. They only have two engineers to approve every construction project going on out here. Understandably they are under a lot of pressure and hence not entirely consistant in their approach. AD Fire Code is based upon the version of NFPA 101 which was current at the time of translation (I get a feeling early or mid nineties). This has been translated from English to Arabic and then back again so you get some chinese whispers. Plus they are very reluctant to approve engineered solutions and prefer to stick to prescription.
If you need any further help or information please don't hesitate to ask.
Will
