9.2.2.1 The
master
of
a
ship
should ensure that:
-
.1 precautions are taken at all times to prevent
flammable and/or toxic vapour from entering a service or control station,
accommodation or machinery spaces on the
ship
;
-
.2 except for vents designed to prevent excess
pressure or vacuum within a cargo space, all openings from cargo spaces
are kept closed during
handling
of flammable
and/or toxic cargoes, or ballast water contaminated with such cargoes,
except with the permission of the
port authority
and
berth operator
; and
-
.3 any tools or equipment used, e.g. for sampling
or ullaging are used in a manner so as not to cause ignition.
9.2.2.2 In the case of flammable cargoes sighting
and ullage ports should be kept closed unless required to be open
for operational purposes. If, for design reasons, they are required
to be open, the openings should be protected by a flame screen which
may be removed for a short period during ullaging, sighting, sounding
and sampling. The flame screens should be a good fit and be kept clean
and in good condition.
9.2.2.3 The
master
of
a
ship
should ensure that, if an incident
occurs during the handling of liquid
bulk dangerous cargoes
or
ballast water contaminated with liquid
bulk dangerous
cargoes
which necessitates a repair to the cargo piping
system or connections, or which interferes in any way with the uninterrupted
flow of liquid
bulk dangerous cargoes
or
ballast water, such
handling
is stopped
and not resumed until adequate safety measures have been taken with
the approval of the
port authority
and,
where appropriate, the
berth operator
.
