ensure that only authorised persons can access them.
All electrical equipment should be regularly inspected to ensure that it is suitable for its intended use. Any electrical faults or other defects should be immediately reported to the appropriate person and properly tagged out and disconnected from any power source. The faulty equipment should be removed and repaired by a competent person.
Parts of electrical equipment may remain live even when the equipment is switched off. Equipment must be tested, verified as being isolated, disconnected from any power source and the system de-energised before any work commences.
Attention should be paid to the maintenance of the emergency source of electrical power and alarm systems supply and backup.
All electrical appliances should be clearly marked to indicate their safe operating voltage.
Circuits and appliances carrying different voltages in the same installation should be clearly distinguishable by notices, markings on distribution boxes and other conspicuous means.
Seafarers should not interfere with an installation intended to prevent circuits and apparatus from being subjected to voltages which exceed those for which they were designed.
Only an engineer officer or other competent person should carry out repairs to electrical installations. A "permit-to-work" should be issued (see section 3.8).
Effective means of ensuring safe isolation of every circuit, sub-circuit and apparatus, such as facilities to lock off isolators, key control or signing, should be provided to minimise or eliminate danger to seafarers.
Every circuit should be protected against overload currents, so as to reduce damage to the system and keep the danger of fire to a minimum.
Redundant circuits or apparatus should be disconnected or dismantled and marked accordingly.
Contact with live equipment should be avoided by:
       placing live parts out of reach;
       effective enclosure of live parts;
       adequate insulation; and
       preventing work on live equipment or plant.
PPE, such as rubber gloves and rubber boots, should be used whenever there is a risk of electric shock but should not be regarded as providing full protection against such a risk.
Suitable fuses or contact-breakers should be placed in each circuit to limit the current to the safe rating for the cable or equipment.
Where fuses are used, they should bear clear markings indicating their rated current and, as far as practicable, their rated capacity.
Only authorised persons should replace fuses. Replacement fuses should be of the correct rating. Effective means (such as a fuse replacement tool) should be used to ensure that persons removing or inserting fuses will not be endangered by any adjacent live parts.
In general, it should not be possible to remove or insert fuses in a circuit unless it has been made dead by means of an isolating device
