The man and the girl who called the police are roommates and live in the same room. When the man came back from work, he couldn't open the bathroom door for a long time. After calling the police, the police opened the door and saw that the girl was killed as soon as she entered. According to the police investigating the case, the possibility of homicide has been ruled out by the police technical department. According to the situation on the spot, the police speculated that it might be that the water heater leaked electricity during bathing, causing electric shock.
Pay attention to the safe use of electricity when using various household appliances. In daily life, we should also pay attention to the safe use of electricity when using various household appliances, and try to turn them off when not in use, so as to prolong the service life of household appliances. It is forbidden to use illegal electrical appliances. Please ask professionals to repair them as soon as possible to ensure the safety of themselves and their families.
I'll tell you how to use the electric heater first. Because the bathroom has no local equipotential, and the house I live in has no ground wire, it belongs to that kind of particularly old building. Therefore, there are serious security risks.
Personally, the circuit of the toilet water heater was reformed. The circuit of the electric water heater is divided into a loop, and then a leakage protection switch is installed on the loop to control the electric water heater independently.
Turn on the electric water heater before going to work, and then let it heat; Go home from work, pull down the leakage protection switch of the electric water heater and disconnect the power supply. Please do this before using the hot water in the electric water heater. Personally, I think only in this way can the use of electric water heaters be guaranteed to be foolproof.
With so much protection, you can still get an electric shock? Because of its large current, the insulation requirements for water heaters are also relatively high. In addition, users pay more and more attention to leakage, and businesses have done enough articles on safety, such as "anti-electricity wall" and "double protection". These are the protective measures of the water heater itself to prevent leakage. Generally speaking, water heaters are difficult to leak electricity, or the insulation system of water heaters is the best among all household appliances.
Self-protection is fragile-there is no problem with water heaters produced by regular manufacturers in this respect, except for inferior water heaters. As the first barrier to the safety of electricity use, long-term burning, aging or induced electricity. In short, the insulating layer is ineffective and prone to leakage.
There is no ground wire at all-there are only two wires in rural self-built houses, and there is no ground wire at all. Even the houses in the city, there are some communities whose ground wires are not well grounded, which is simply decoration. So you think it's a ground wire, but it's actually an ordinary wire. The protection function is even more impossible.
You must install a leakage protector and make sure that it is in good condition. In the shower, you said you couldn't get rid of any electric shock current, because the hose was burning and you were covered with water. When the leakage current is less than 30ma, your leakage protector will not trip, but if the current acts on you for a long time, you are hopeless, and whoever saves you may get an electric shock. If someone gets an electric shock in the shower, you must first cut off the power supply and then rescue them. But how many people have this psychological quality, a lot.
Leakage protector must be installed, and it must be in good condition. 15ma leakage protector can be installed in the socket circuit of the water heater, and the water heater must be reliably grounded. The safest way is to unplug the water heater before taking a bath and replace it with a new one after its service life.
As long as the shell of the equipment has metal parts, measures should be taken to prevent leakage. The heating tube of the water heater leaks electricity, and the leakage current flows out with the water flow. Because the magnesium rod is not cleaned for a long time, it is also consumed. The scale produced by water impurities corrodes the heating pipe, and the heating pipe rusts over time, leading to leakage.
In short, as long as electricity is used, there is a danger of electric shock. Only when used correctly and safely can you be safe all your life. Whether it is electric water heaters, induction cookers, rice cookers, refrigerators, washing machines, electric fans, air conditioners, electric kettles, etc. As long as the shell of the equipment has metal parts, measures should be taken to prevent leakage.
Buy a regular brand, install it correctly, and there are few problems in the process of use. It is also recommended to invite professionals to check at home to avoid leaving security risks!
