Electric shock prevention

My intention with this hub is not speaking as an expert, but only give you a few tips about low voltage systems. We know that electricity is an energy trying to seep through the floor using for it anything that can serves as a bridge, as a metal, concrete or even your body. It is also important to know that most electric 110-volt systems are made of two main wires, the phase and neutral. The phase wire is energized and will result in a shock, and the other is just to receive power after making work production, and will lead it to the earth. This is exactly why we can touch a bare wire, even if it is interconnected with the system and do not take shock, that is, the wire is probably the neutral one and can not cause shock. It is important to know that even if you touch the phase wire, shock will occurs only if you are in touch with neutral wire, floor, walls, etc. In Brazil, usually the neutral wire is blue, while the phase is black or red. In some installations you can find green wires, which are the internal ground used to increase security and stability. The fact is that the shock can be fatal depending on conditions such as: state of health, skin resistance and duration of exposure to shock. The skin resistance is reduced among other factors, by water, making the shock more dangerous. Even rubber shoes can lose their resistance to the passage of electricity if they are wet. Most home fatal accidents occurs becouse the energized wire clamps the person, making the time exposed to shock longer. In these cases, if the ground or the victim is wet, the situation becomes dramatic. Then I'll give the top tips that i use today to prevent accidents with shocks or mitigate the consequences if they arise:

1) Never handle electrical equipment if you or the floor is wet (showers are exceptions because they are designed for this).

2) Always disconnect the main switch before handling any electrical installation, especially if you're not highly trained for this.

3) If you suspect that shock can occur on some structure or equipment and need to touch on it, wear dry shoes and not touching walls, floors, etc.

4) Avoid handling electrical installations in places where you can be off balance and fall due to scare of a shock. Many deaths are caused by the fall, not the shock itself.

5) Finally, never place your body or parts between wires or electrical system, because you can stay arrested.
