 و this unit will be talking about the requirement should be taken to protect from the electrical hazards. The most common electrical hazard will be happened because of exposed the electrical parts, overload circuits, detective insulation, unproper grounding, damage power tools, overhead power lines or weight condition. Exposed electrical parts include perical box or the electrical terminal of the motor application or the electrical equipment without cover. Overloading circuit increases the potential for the fire to occur. To be happened and to be caused by too many devices are plugged into one circuit or the wire insulation melt or to unproper overcurrent protection device used. Overcurrent protection device includes circuit breaker, fuse or GFCI to be ground for circuit interpreters. A circuit breaker is automatically type traps or device to be shut off the current in case of the dangerous. It will be happened due to the overload circuit. A fuse contains an internal bar that melts and shut off the current in the case of the overload. GFCI to be detect the current leaking from a circuit to the ground and shut off the current and protect the circuit. Defective insulation. To protect yourself from the electrical shock, electrical wire are insulated by plastic or rubber covering. Insulation prevent the conductor to contact with each other or with the bubble which will be caused by the electrical short. Grounding. When the electrical system is properly grounded there is bath that allow the current to travel to the earth. By this it will protect the workers and protect the device. Power tools that are damaged or not properly maintained can cause you a serious injured. So make sure all your power tools it will be maintained in the suitable time. Overhead power lines usually is not insulated. And the causes more than the help of the electrification for the workers. So should be carefully when you work inside this power lines. With conditions. With conditions that are hazard because you can easily the bath for the electrical safety through your body. There are many reasons to create the weight condition. Stand in the water with clothing, high hamlet and perception. As summary for this unit is important to start safe and stay safe around the electricity. In order to do this you have to know the hazard. Type of the hazard. Plan you work and plan your safety. Avoid the weight working condition because it will be dangerous. Also avoid the overhead power lines. And use the proper wiring and the contactors. Also use the maintain tools properly and the end where the suitable PPE. And thank you so much.
