Safety precautions on the use of electrical systems

Electricity is an important resource which makes it possible for us to use tools making the current modern era easy to live in, as we are served by machines powered with energy, but it is also unfortunately a source of very high risk for life and the danger one faces if not paying adequate attention to safety standards, necessary to protect the person, should not be underestimated.
Following safety precautions when using electrical devices, like with an electrical switchboard, will make it possible to not compromise one’s safety.

  1. When one is working on electricity, it is imperative to stay away from water and to thoroughly dry one’s hands before touching electrical equipment or circuits, as water increases conductivity of current which may flow through the person.
  2. Immediately replace worn out cables, broken or damaged plugs or sockets, previously turning off current through by setting the electrical panel to "OFF".
  3. Work with rubber gloves that will act as an insulators, wear glasses to protect your eyes and make sure the equipment or device you are going to fix is completely off; you can check this with a meter which will light up if electric current is flowing through the wires.
  4. Do never use a steel or aluminum ladder when working on sockets in your home, because having a grounding, in case of electrical overload, will make current go through you before it reaches the ground. You can use wooden or fiberglass ladders without any danger.
  5. Install circuit-breakers in the bathroom and in the kitchen, to prevent electric shocks, and check them at least once a month to be sure they are working properly.
  6. If you need to dig up a buried cable, remember that moist soil acts as a good conductor of electricity, so it will be a big risk to yourself, especially if you are using a shovel which is likely to damage the cable; use insulating gloves and dig with your hands to reach the cord.
  7. A capacitor removed from a circuit is still a device storing energy and, even if removed, can still give you an electrical shock. To avoid this, after removing it from the circuit, touch its electrodes with the tip of two insulated screwdrivers to make it discharge, in the case of a high voltage capacitor; the same operation may be performed using a 12 V light bulb, the bulb will lit up using all the stored energy.
  8. When soldering circuits, protect your eyes from fumes with glasses and keep the soldering iron in a secure location when not using it, because it becomes very hot and can easily cause burns.

The main risks you are exposed to when working with electricity, can be summarized in electric shocks or burns by contact with live parts, injuries caused by exposure to electric arc, fires caused by malfunctioning electrical circuits or equipment, bursts of electrical equipment not complying to standards, static electricity igniting combustible dust like in a spray paint booth. Each one of these can be avoided with proper precautions which will save the life of oneself and others.
