Often we think that the danger of electric shock can only be caused by a high voltage circuit.<\/span> this is not true.<\/span> Many cases of occupational accidents electric shock, which is fatal to until death caused by low voltage of 120 volts.<\/span> If among us ever electric shock but safe did not have a bad result, the incident should not be used as a handle, perhaps you are in luck.<\/span><\/p>\n

Do not rely on luck in the works.<\/span> Remember, always work with safety and the safety conditions.<\/span> Fatal and whether or injury caused by electric shock depends on the human body resistance to current flow or electrons.<\/span> The amount of current flow is the number of electrons flowing through the human body, which is measured in amperes (A).<\/span> Electrical shock will occur, when our bodies become part or passive elements of an electrical circuit.<\/span><\/p>\n

According to the concept of electric circuits, there are three factors that could cause electric shock, the resistance, voltage and current.<\/span> A result that can be caused by electric shock depends on the resistance of the human body and the value of the touch voltage.<\/span> The resistance of the human body varies from one person to another.<\/span> The lower the resistance of the human body, the greater the consequences can be caused by electric shock.<\/span><\/p>\n

The resistance of the human body can be divided into two, namely external and internal.<\/span> External resistance is influenced by human skin and internal resistance is affected by the body’s tissues and blood system.<\/span> Dry skin is a good electrical insulator.<\/span> Skin moist, wet can lower the body’s resistance value, and therefore the intensity of the electric shock will be even greater if our hands wet.<\/span><\/p>\n

Internal resistance will be lower when the levels of salt and water in the blood is higher.<\/span> The magnitude of the resistance value of the human body has a wide range, as shown in Table 1.1.<\/span> To measure the resistance of the body can be used a measuring tool ohmmeter.<\/span><\/p>\n

If someone personnel are working on the electrical panel using a screwdriver to act extra carefully.<\/span> Because it allows occurred thing tidakdiinginkan eg screwdriver electrodes attached to the panel frame is made of metal, while the screwdriver tip touch-voltage parts.<\/span> This event will lead to sparks which can cause things that are not desirable, as shown in Figure 1.11.<\/span><\/p>\n

If the resistance of the circuit is very small, the current flowing in the circuit becomes very large.<\/span> Nailai the amount of electric current that flows through the human body by 15 miliamper already can be fatal to the human soul.<\/span> Compare with the amount of electric current flowing in a 15 watt incandescent lamp, which is 68 miliamper.<\/span><\/p>\n
