By paying attention and following standard operating procedures that apply, then accidents due to electric shock can be avoided, even if we have to work in a high-voltage area though. The occurrence of electrical shock, indicating that the equipment is not handled properly. The following practical given safety instructions, to avoid the danger of electrical shock, namely:
(1) In conducting the installation of electrical equipment, always follow the standard procedures that apply both locally and nationally.
(2) Ensure that the mains power supply has been decided through the distribution panel or the existing control panel.
(3) Make sure the equipment is still voltage or no voltage.
(4) When working in a wet make sure it wear personal protective equipment which is feasible and safe.
(5) Make sure your body does not become part of the electrical circuit, so exposed to electric shock.
(6) Always use hand tools engine equipped with grounding wire.
(7) Do not wear rings, watches or other jewelry while working with the power source.
(8) Do not use an aluminum ladder when working near electrical circuit that is active.
(9) Use of insulation shoe equipped with a sole and heel.
(10) Make sure that the equipment would be used in prime condition.
To ensure safety in the electric voltage area, there are several things to be considered, namely:
not touch something we do not want.
keep or move the other equipment, up to three meters of high-voltage grid.
not close contact (activate) the switch we do not know its function.
as far as possible avoid working on that still-voltage circuits.
not touch a grounded object while working on an electrical equipment.
ensure that there is value in the amount of voltage electrical equipment that is being repaired. Because in some brackish have many variations of voltage, for example 24 VDC, 120 VAC, and 440 VAC.
not touch the engine or electrical equipment that is being worked.
ensure that all connections or electrical connections in a state of solid and strong, because in many cases it can trigger a fire caused by electricity.
when working on equipment that voltage above 30 volts, using only one hand and the other hand in order to keep the danger of electrical shock through the shoulder can be avoided.
Empty or dispose of electric charge on the capacitor before the capacitor is opened or removed.
In the event of an accident electric shock, the patient usually falls after power outages. If the scene was compromised, for example in the top of the mast, a sloping roof, or horses buildings, often people experience more severe accidents. In this case the first aid performed by an expert or assistant practitioners, is not intended to take over the job of the doctor but rather merely an emergency treatment until the doctor comes.
To help victims of electric shock, the first thing to do is release the victim from contact against the tool-voltage electricity. This can be done by using a stick made of insulating material, such as wood or plastic. Do not touch the victim until the victim is freed from the power supply voltage.
