Electrical power must be turned off while the equipment is being inspected or repaired. To make sure that no-one turns the power back on, tagout is being used. Tagout means that a tag ‘danger’ is placed on the source of the electrical power to prevent an outsider from turning it ack on.

Clothing of an electrician should fit perfectly to avoid getting stuck or stumbling. Electrician should not wear a tie (or anything else that hangs loose) or rings (gold and silver conduct electricity).

It is important to remember that voltage does not kill people, current does. However, there have been occasions when people have been killed by 100 volts AC and with 42 volts DC. Currents between 100 and 200 milliamperes are fatal without exceptions.

One can get electric shock when he/she comes into contact with two conductors of a circuit or when he/she gets in the middle of the electrical circuit (as a link in this chain). This may result as burning marks on the skin, light shock or even death. Thatswhy it is important to avoid unfamiliar ‘non-safe’ electrical devices.

First thing you should do when discovering someone having an electric shock, is to remove him/her from the circuit. Definitely remember to protect yourself with dry insulating material. Do not touch the victim with bare hand until the victim has been removed from the circuit.

All electricians should have basic knowledge of CPR (cardiopulmonary resuscitation) to help their co-workers when necessary. It is important to remind electricians during medical courses not to give artificial ventilation to a person who is breathing naturally.
