GENERAL HAZARDS FOR SHIP AND TERMINAL

Correct functional operation does not necessarily imply compliance with
the required standards of safety.

4.4.4.2 Inspections and Checks
arrangements fitted on board.ย์ฝกพาณิชย์นาวี
All equipment, systems and installations should be inspected when first
installed. Following any repair, adjustment or modification, those parts of
the installation that have been disturbed should be checked.

If at any time there is a change in the area classification or in the
characteristics of the flammable material handled at a terminal, a check
should be made to ensure that all equipment is of the correct group and
temperature class and that it continues to comply with the requirements
for the revised area classification.

4.4.4.3 Maintenance of Electrical Equipment
The integrity of the protection afforded by the design of explosion-proof
or intrinsically safe electrical equipment may be compromised by incorrect
maintenance procedures. Even the simplest of repair and maintenance
operations must be carried out in strict compliance with the
manufacturer’s instructions in order to ensure that such equipment
remains in a safe condition.

ึ
This is particularly relevant in the case of explosion-proof lights where
incorrect closing after changing a light bulb could compromise the
integrity of the light.
4.4.4.4 Insulation Testingูน
In order to assist with routine servicing and repair, ships should be
provided with detailed maintenance manuals for the specific systems and

Insulation testing should only be carried out when no flammable gas

4.4.4.5 Alterations to Terminal Equipment, Systems and
Installations
No modification, addition or removal should be made to any approved
equipment, system or installation at a terminal without the permission of
the appropriate authority, unless it can be verified that such a change
does not invalidate the approval.

No modification should be made to the safety features of equipment that
relies on the techniques of segregation, pressurising, purging or other
methods of ensuring safety, without the permission of the engineer
responsible.

When equipment in a terminal hazardous zone is permanently withdrawn
from service, the associated wiring should be removed from the
hazardous zone or should be correctly terminated in an enclosure
appropriate to the area classification.

When equipment in a terminal’s hazardous zone is temporarily removed
from service, the exposed conductors should be correctly terminated as
above, or adequately insulated, or solidly bonded together and earthed.
