Any electrical mains socket or cable that looks defective must never be used and should be reported to the user or the appropriate body.
SERVICING COMPUTERS
Before undertaking any servicing you must
- Remove any hand and arm jewellery (this includes watches rings and any item that may come in contact with a live circuit.)
- In almost all cases before maintenance is carried out on the equipment, it must be switched off and isolated by disconnecting the AC mains cables. Two exceptions to this rule apply:
- Where a fault can only be diagnosed with the mains connected (for example if a CPU fan is suspected of being faulty)
- Grounding purposes (If the manufacturer requires that the AC mains cable be attached for grounding purposes)
- Ground yourself (to prevent electrostatic discharge before touching any static sensitive devices.)
Working on any electrical appliance requires strict procedure, not only for you but for other users and we must be aware of the areas within the equipment that can cause electrical hazard.
Even the most experienced engineer can receive an unpredictable electrical shock that could be fatal if no one else is there to help, so avoid working on electrical equipment alone.
