1.3 Cargo lines forward or aft of the cargo area,
except at the loading station, should have welded connections. If
necessary, expansion joints may be permitted. Valve connections may
be flanged. Such lines should be clearly identified and segregated
either by two valves situated in the cargo area which can be secured
in the closed position and provided that the efficiency of the segregation
can be checked, or by one valve together with other closing appliances
providing an equivalent standard of segregation, such as a spool piece.
1.4 The shore connection should be fitted with
a shutoff valve and a blank flange. The blank flange may be omitted

of cargo piping to the satisfaction of the Administration.
1.7 Arrangements should be provided for cargo
piping located outside the cargo area to be cleared of oil and inerted.
Due consideration should be given to isolation between cargo and the

1.8 When stern loading and unloading arrangements
are in use, openings and air inlets to enclosed spaces within a distance
of 10 metres from the cargo shore connection should be kept closed.
1.9 Means of communication should be provided
on board between the cargo control station and where the cargo shore
connection is located.
1.10 The provisions of regulation II-2/56.6 to 56.8.3 inclusive should apply
to the exterior boundaries of superstructures and deckhouses enclosing
accommodation spaces which face the cargo shore connection, the overhanging
decks which support such accommodation, and the outboard sides of
the superstructures and deckhouses for the specific distances from
the boundaries which face the cargo shore connection.
1.11 A fixed foam fire-extinguishing system covering
the loading and unloading areas should be provided. The system should
be to the satisfaction of the Administration.
1.12 Electrical equipment within a distance of
3 metres beyond the cargo shore connection should be of a certified
safe type.
1.13 Bow and stern loading and unloading arrangements
should not interfere with the safe launching of survival craft, and
provisions should be made to the satisfaction of the Administration
to protect launching stations from sprays in case of hose and pipe
bursting.
