Deacon, The 97 regs had certificated premises as "excepted workplace", the amendment removed this meaning that certificated premises now had to comply with the workplace regs.

The main differences between the workplace regs and the RRO are;
All 'relevant persons' are protected in the RRO, the WP regs protected employees only.
The RRO looks at the reduction of risk then protecting relevant persons from the remaining risk, the WP regs just looked at protecting employees from risk.
The maintenance of fire fighting provisions is now considered under the RRO.
The RRO applies to any place (with a few exceptions, domestic etc) and the WP regs applied strictly to workplaces (With a few exceptions, many removed by the 99 mods).
Also the need for a fire risk assessment was technically in the Management Regs, but this need was created by the WP regs modifying parts of the management regs.
Re: ADB and the RRO. I think someone is getting confused with the Building Regs and ADB. If the question relates to Building regs vs the RRO, then it would possibly help you to search for details surrounding 'the holroyd distinction'. It applies essentially to the FP act and the Building Regs, but the key stuff is in there.
