Wee Brian,
Section 182 guidance (Guidance made for the Licensing act in the same vein as ADB and CLG guides) states quite clearly that fire safety conditions can't form part of a licence any more. This is not just guidance, it is actually stating a fact because if fire safety conditions are put on a license then Article 43 of the RRFSO makes them completely meaningless*....
If you are not complying with the fire safety legislation, then you are potentially not complying with the licensing act, but the licensing authority expect you to comply with all the other legislation. As such, they expect the relevant authority to deal with it through their relevant legislation. (Probably no different to how we expect the process risk to be covered by the HSE.)
At the application stage the Fire Authority could try to object to the license if they thought that fire safety conditions meant that public safety was an issue. The LA could then refuse to issue the license on those grounds, but they cannot put any fire safety conditions on the license. However, most Fire Authorities will deal with shortcomings such as these directly under the RRFSO.
There is nothing in any official guidance documents that says that compliance with BS9999 means that the relevant legislation is being complied with. (It is not mentioned in ADB, it is not in the CLG guides, and it is not in the Sec. 182 Guidance)
In a nutshell, protection of escape routes is nothing to do with the licensing authority, and it is ultimately up to the FRS (in most cases) whether a BS9999 solution complies with the RRFSO.
* From the RRFSO Article 43: (2) At any time when this Order applies in relation to the premises, any term, condition or restriction imposed by the licensing authority has no effect in so far as it relates to any matter in relation to which requirements or prohibitions are or could be imposed by or under this Order.
