Hi Mike,
Thanks for your input.
Taking your example findings and relating them to my previous post, I have had a quick scan through the Document M and I would summarise my understanding of the requirements as follows:
IF a building was new, or being materially altered or extended or changing use to a public building, hotel etc. etc. (Clause 0.1) AND there was only one W.C. on any particular storey (Clause 0.4 Example 1) then that w.c. would be designated as the facility for 'disabled' persons, so THEN it would be fitted with a visual (and audible) alarm warning device (Clause 5.4.g)
From this, relating back to the original question of why the council officer insisted on beacons being fitted in all the toilets, surely;
1) They would not yet be required if the building wasn't new, being extended/materially altered or undergoing a change of use to a 'public' building.
2) Only one w.c. facility per storey would be designated a disabled w.c. anyway, and then require the appropriate facilities.
I accept that other factors, such as a fire risk assessment, may have a bearing on the requirement for the beacons, but the original point asked was why the Council Officer insisted Document M required them in every w.c. in every building
I accept that my summary was based on a quick scan through Document M and I welcome any advice that explains why I might be wrong!
