Safety of the electrical engineer this progressively over 20-30 years ago, when modern. There are laws about safety and OSHA safety rules (which are defined on a mask protective helmet and protective equipment at work). With the use of protective equipment, safety and operating principles that will make working with electrical equipment safety. Which, if considered, and treated properly it will work safely power. Electrical engineer must know and be able to master the basics of electrical applications, and security. If you didn't own it security equal to make your colleagues is not safe. Always remember that you shall prevent an accident before it happens. If the electrical work must have knowledge and an understanding of electricity and are correct. At any time, if there is a suspicion or did not understand about the power to question people who have knowledge, always. Reporting to the supervisor as soon as it found unsafe working conditions. Faulty appliances and are not safe or unsafe to do the job.Fuse before removing or changing the fuses must be sure before that cut power from the circuit with a switch, and there is no electricity at the fuse. The fuse must be used to decrypt tool for pulling fuses (fuse puller) specifically designed to pull the fuse to the power and (hot side). When you want to insert the new fuse into the fuse holders on the load (load side) first, and then insert the power plug into the top.Electric vacuum Power vacuum caused her body to touch or touch a power line, two lines or body is part of the electric current, but in both cases, it makes your heart and lungs 2 stopped working and the effect of the heat caused by the electric current flowing through the body, causing a burn in a stream flowing in and out of the body.Prevention is the best way for maintaining electric vacuum. Keep, beware that voltage at any level is dangerous, and trying to learn to know the story of power and follow all the steps.To use the electric tool must ensure that the machine is completely and in a safe place, make sure that the electrical cable is damaged, there is a line for line 3, which continued into the soil in order to prevent electric leakage. According to the theory, if a leak occurs, the power tools or electrical insulation and leakage occurs, power will flow into the soil via electric wires 3 lines instead of flowing through the body of the user.
