At least once every five years, the following inspections
should be carried out for the specified equipment.
9.1 Fixed gas fire-extinguishing systems
Perform internal inspection of all control valves.
9.2 Foam fire-extinguishing systems
-
.1 perform internal inspection of all control
valves;
-
.2 flush all high expansion foam system piping
with fresh water, drain and purge with air;
-
.3 check all nozzles to prove they are clear of
debris; and
-
.4 test all foam proportioners or other foam mixing
devices to confirm that the mixing ratio tolerance is within +30 to
-10% of the nominal mixing ratio defined by the system approval.
9.3 Water mist, water spray and sprinkler systems
-
.1 flush all ro-ro deck deluge system piping with
water, drain and purge with air;
-
.2 perform internal inspection of all control/section
valves; water quality testing should be conducted in all corresponding piping
sections, if not previously tested as outlined in paragraph 7.5.18 within the last
five years;
-
.3 check condition of any batteries, or renew in
accordance with manufacturer's recommendations; and
-
.4 for each section where the water is refilled after
being drained or flushed, water quality should meet manufacturer's guidelines.
Testing of the renewed water quality should be conducted and recorded as a new
baseline reference to assist future water quality monitoring for each
corresponding section.
Perform hydrostatic testing of all steel self-contained
breathing apparatus cylinders. Aluminium and composite cylinders should
be tested to the satisfaction of the Administration.
