4.4.2.3 Application of Hazardous Area Classifications to a
Tanker at a Berth

When a tanker is at a berth, it is possible that an area in the tanker that is
regarded as safe may fall within one of the hazardous zones of the
terminal. If such a situation should arise and, if the area in question
contains unapproved electrical equipment, then such equipment may have
to be isolated whilst the tanker is at the berth.

4.4.3 Electrical Equipment

Fixed electrical equipment in dangerous areas, even in locations where a
flammable atmosphere is to be infrequently expected, must be of an
approved type. This equipment should be properly maintained so as to
ensure that neither the equipment nor the wiring become a source of
ึ
ignition.

4.4.3.2 Closed Circuit Television
If closed circuit television is fitted on a tanker or on a jetty, the cameras
and associated equipment must be of an approved design for the areas
in which they are located. If they are of an approved design, there is no
restriction on their use. When a tanker is at a berth, any servicing of this
equipment should be subject to prior agreement between the ship’s
Responsible Officer and the Terminal Representative.

4.4.3.3 Electrical Equipment and Installations on board Ship

Fixed electrical equipment and installations in tankers will be in
accordance with classification society or national requirements, based on
the recommendations of the IEC. Additional recommendations in respect
of the use of temporary electrical installations and portable electrical
equipment are given in Sections 4.3 and 10.9.4.

4.4.3.4 Electrical Equipment and Installations at Terminals

At terminals, the types of electrical equipment and methods of installation
will normally be governed by national requirements and, where
applicable, by the recommendations of the IEC.

4.4.4 Inspection and Maintenance of Electrical Equipment

4.4.4.1 General
All apparatus, systems and installations, including cables, conduits and
similar equipment, should be maintained in good condition. To this end,
they should be inspected regularly.
