I.6.1 General
In addition to the checks recommended in I.2, I.3, I.4 and I.5, the checks described in I.6.2 and
I.6.3 should be undertaken once every six months.
Arrangements should be made for six-monthly inspections and tests to be carried out by competent
persons on the fire detection and fire alarm systems, the sprinkler systems, any extinguishing
systems, the emergency and escape lighting systems and the firefighters lift, for any defects found
to be logged and the necessary action taken, and for certificates of testing to be obtained.
I.6.2 Fire doors
All fire doors should be inspected every six months. In particular, it should be ensured that:
a) heat-activated seals and smoke seals are undamaged;
b) door leaves are not structurally damaged or excessively bowed or deformed;
c) gaps between the door leaf and the frame are not so small as to be likely to bind, or so large
as to prevent effective fire and smoke-sealing;
d) hanging devices, securing devices, self-closing devices and automatic release mechanisms are
operating correctly.
