Electric power is silent, invisible and potentially lethal.
The basic rule is simple: consider all cables and electrical equipment as live, under voltage, until tested and proven to the contrary.
♦ Uninsulated electrical parts;
♦ Aerial power lines;
♦ Poorly insulated cables and connections;
♦ Damaged electrical tools and equipment;
♦ Use of electrical tools in humid environment.
Before starting work:
♦ Request a work permit (medium and high voltage) and understand its requirements; ask if you have any doubts / if there are any unclear issues;
♦ Make sure that all hazardous power sources of insulated;
♦ Comply with all the authorisation / permit requirements.
General rules to retain:
♦ Consider all cables as live, under voltage;
♦ Never touch the suspended cables, but report them to the supervisor;
♦ If you are not a qualified electrician, do not attempt any electrical repairs;
♦ Never use electrical equipment if your hands are wet or your feet are submerged in water;
♦ If the electrical equipment releases sparks or smoke, turn off the power supply and report the situation to your supervisor;
♦ Report triggered fuses immediately. They may indicate an overload or short-circuit;
♦ Use only appropriate and authorised electrical equipment; the installation and inspections performance must be carried out by an authorised electrician only;
♦ It is mandatory to observe the warning signs installed at the points of access to the electrical installations;
♦ Make visual inspections of plugs, sockets and cables – if any damage occurs, immediately put them out of operation and report them immediately;
♦ Do not overload the sockets – use only one plug per socket!
♦ You should never work on live under-voltage equipment;
♦ All electrical equipment must be insulated if put out of operation.
Electricity cannot be seen, but its effects may be dramatic!
