4.2.1 Shipowners and masters should ensure that
adequate security arrangements are in place which, as far as practicable,
will prevent intending stowaways from getting aboard the ship, and,
if this fails, as far as practicable, will detect them before the
ship leaves port or, at the latest, before it arrives at the next
port of call.
4.2.2 When calling at ports and during stay in
ports, where there is risk of stowaway embarkation, security arrangements
should at least contain the following preventive measures:
-
.1 all doors, hatches and means of access to holds
or stores, which are not used during the ship's stay in port should
be locked;
-
.2 access points to the ship should be kept to
a minimum and be adequately secured;
-
.3 areas seaward of the ship should be adequately
secured;
-
.4 adequate deck watch should be kept;
-
.5 boardings and disembarkations should, where
possible, be tallied by the ship's crew or, after agreement with the
master, by others;
-
.6 adequate means of communication should be maintained;
and
-
.7 at night, adequate lighting should be maintained
both inside and along the hull.
4.2.3 When departing from a port, where there
is risk of stowaway embarkation, a ship should undergo a thorough
search in accordance with a specific plan or schedule, and with priorities
given to places where stowaways might hide. Search methods, which
are likely to harm secreted stowaways should not be used.
4.2.4 Fumigation or sealing should not be carried
out until a thorough search of the areas to be fumigated or sealed
has taken place in order to ensure that no stowaways are present in
those areas.
