Before any work on electrical equipment is carried out, fuses should be removed or circuit breakers opened to ensure that all related circuits are isolated and de-energised. If possible, switches and circuit breakers should be locked open or, alternatively, a 'not to be closed' notice attached. Where a fuse has been removed, it should be retained by the person working on the equipment until the job is completed. A check should be made that any interlocks or other safety devices are operative.
Additional precautions are necessary to ensure safety when work is to be undertaken on high-voltage equipment (designed to operate at a nominal system voltage in excess of 1000V). The work should be carried out by, or under the direct supervision of, a competent person with sufficient technical knowledge using a permit to work system.
Any test meters used must be rated for the voltage being tested with meter probes having only minimum amounts of metal exposed and insulation of both probes should be in good condition. Care should be taken that the probes do not short circuit adjacent connections. When measuring voltages that are greater than 250V, the probe should be attached and removed with the circuit de-energised.

12.1              Flexible cables, portable lights, electric tools and other equipment
Battery powered tools should be used to minimise the risks associated with electrical leads. All flexible cables should:
       be of sufficient size and current rating for the purposes for which they are to be used;
       be constructed, insulated, secured and protected to eliminate or minimise electrical risks;
       not be laid on surfaces that are oily, wet or where corrosive liquids are present;
       be kept clear of moving loads, running gear and moving equipment;
       not be used to lift portable lamps or portable tools to which they are connected, unless specifically designed for that purpose.
Every electrical connection should be of suitable construction with regard to conductivity, insulation, mechanical strength and protection, taking into account the need to use such equipment in exposed locations.
Cables and conductors should be mechanically protected and properly and durably insulated at points where they are joined, branched or led into any apparatus. For these purposes junction boxes, sleeves, bushings, glands or equivalent connecting devices should be used.
Where practicable, flexible cables should be joined by junction boxes or plug and socket couplings, and the attachment should be made by screwing, clamping, soldering, riveting, brazing and crimping or equivalent means.
Where armoured cables are joined, care should be taken to continue the conductive bond between the armouring of the cables by bridging the junction boxes.
All conductors and apparatus that may
