I saw this coming years ago folks were there would be issues in relation to blitz fire detection in buildings. In NI anyway, and maybe elsewhere in the UK, some Building Control Inspectors interpret where it says in the Regs:-
Means of escape
A building shall be so designed and constructed that in the event of a fire there is—
(a)where appropriate, adequate means of automatic detection;
(b)adequate means of giving warning; and
(c)adequate means of escape, which can be safely and effectively used at all material times.
as meaning, regardless of the "where appropriate" bit, whack it in everywhere.
As and example I have seen full AFD in a small stable block. The owner said that Building Control made her install it.
This requirement to install such a system in such a premises was obviously made with due regard to nothing other than someone seeing the words "means of automatic detection" in the Regulations without giving consideration to the whether it would be appropriate or not to install.
So I'm afraid the Fire & Rescue Service is reaping the sowings of others.
I think it should also be said that the Fire Service do not get turned out to false alarms. They get turned out a report of a fire which in some cases is an automatic report, be it to the occupiers or otherwise. It is only a false alarm, or unwanted call, when no fire is found. But the technology which many occupiers were required to install by the authorities is indicating a fire, not a false alarm, and they respond accordingly by calling the fire service.
Did they not see it coming?
I'm certainly not saying that there is no place for AFD. Clearly there is in certain high risk premises, but a more considered approach to determining where detection is appropriate should be the order of the day.
Perhaps the Regulations should say that AFD should not be installed other than when it would be considered appropriate for a specific risk.
