Hi All,
I have a query with regard to Fire Doors on Service Risers in multi-storey buildings. I appreciate that as regular access is not necessary and therefore best practice would be to lock the door and control the key.
Is there any specific regulation requiring this? My thoughts are the Building Regs may address this specifically but I cannot find the reference.
I appreciate that the MHSWR and HSWA along with others provide a format for the decision making process and a hierarchy of control, so please no "Do a Fire Risk Assessment!" answers.
Specifically - Do Fire Doors on Service Risers need to be kept locked or would a simple "Keep Shut" approach be enough?
Thanks in advance.
Tony

Hi Tony, my answer is, as usual, "it depends"
If the risers contain electrical switchgear, meters, fuseboxes etc then yes. If they contain only innocuous water pipework then maybe - it depends on whether the floor openings are effectively fire-stopped and whether the riser cupboards are being used for random storage of combustible stuff.
In the estate of offices that I advise on there is a mix of locked riser doors (using a simple quarter turn latch for which the caretaker has keys), shut doors relying on friction to hold them closed and some left ajar.
I have recommended that all the floor slab openings are fire-stopped and this is gradually being done.
In short I think it is down to whether the contents are likely to be tampered with and whether leaving them open will significantly degrade the building's fire breaks.

The new building regulations will not permit any open duct or void between fire sections.
For example, even every cable entry must be sealed into ceilings if there are different fire sections above and below. Gone are the days when you could leave a hole for a cable and its connections above a ceiling rose to a light fitting.

I've always understood that intumescent seals should be required between fire sections. And written authorisation to break a new hole.
