It's getting cold
The best thing to do is wash one
A nice hot bath
But be careful
Don't make good things bad
On 2 october, during the fourth of october, a family of 54-year-old yellow-named men took a bath in guangzhouElectric water heaterThe power outage caused the death of the electrocution。
Death certificate issued by the police
On the day of the incident, it was reported that several telephone calls by relatives had failed to reach the victim and the police had called the police, who visited the scene and found that the victim had fallen into the bathroom and that there had been a leak。
According to media reports, photographs of the scene provided by the family of the deceased showed a visible black burn on the wrist of the deceased, as well as a disorderly electrical layout in the bathroom. She told the press that after a preliminary examination by the family, there was no room in the rental houseBattery protectionDevice。
Field environment
On 18 october, a reporter from the late sheep town newspaper came to the scene of the incident and found that the house was still blocked by the police and sealed on the door。
Local resident council staff told journalists that the deceased was a tenant. Most of the inhabitants of the same floor are reluctant to talk about it。
There's still a seal on the main gate
Journalists visited the neighbourhood and found the building to be an old residential building of over 20 years old. On the convulsive exterior wall, mixed wires intersect。

In an old building like this
The safety of electricity is a real concern
Once an accident happens
It's too late to react
Know how electrical works
To be more sensitive to security

Let's just take the secret from the water heater
Common electric water heaters
There are two main groups -
Water storage electric heaters and, in other words, heat electric water heaters (mostly gas heaters)。
It was reported that water-storage electro-heaters were used at the site and that the work of such water heaters was as follows:
When the heater is fully water-powered, the internal heater heats up the water in the electric water heater's guts, when the heater reaches the established temperature, the circuit is cut off, the heating is stopped, the whole body begins to warm until the temperature is reduced to a certain temperature, the electric heater is reheated, repeating the process to the result that there is always hot water available。
A magnesium bar has been inserted into the electro-heated water heater, whose effect is critical, because it reacts easily with minerals in the water while heating, but magnesium activity is greater than iron or copper in the heater bar, so that the magnesium rod reacts with the minerals one step ahead of the electro-heating rod, thereby replacing the heater bar with a corrosive effect

So..
It's important to change magnesium sticks regularly
After all, when the magnesium rod fails, the heater itself begins to corrosive, with a high probability of a leak
It has been suggested by experts that, depending on the local water quality situation, “generally the guangzhou situation is that the water quality is alkaline and should be replaced almost once in two years”
A leak protection device, a generic term of a series of leak-proof measures: when there is a leak in the electric water heater or when the load current is overrated, it jumps automatically, cutting off the power and avoiding accidents. (bearing: this function must be reliable in good local conditions!) if it's bad, it's a big discount

An “enhancement wall”, which is placed within the water pipe, is formed by the determination of the diameter and distance of the pipe through the selection of the piped material in the water heater (insulation material). When the water heater works, even if electricity is available, the timid water is reduced by the electrical resistance of the water itself when it passes through the “wall”。
It's very important
The electric water heater is used to heat the water, mainly for bathing, causing serious accidents and loss of life in the event of a leak. It is therefore necessary to connect, without exception。
Even when there is a leaked circuit breaker (like a protected leak plug), the surface is connected. Grounding is an essential prerequisite for the operation of leak protection. If the heater does not land, the leaks in the water heater's own belt and in-house leakages will not work. When power leaks, people become the only receiver of electric shocks, so it is necessary to connect to the surface to ensure safety. If there's no surface, you can find a steel band that's between 1 and 2 metres underground, and you can connect to it。
Precautionary little tip
1. Power outages before showers: if conditions permit, it is advisable to turn on the water heater one hour in advance and turn off the power before bathing
2. Unwetted hand extraction switches: not only on water heaters, but also when touching any electrical switches, you must dry up the water on your hands, with multiple mineral content in the running water and conductors
Three, one year later, the spare parts are replaced: one year after the heater has been in service, the maintenance staff will be asked to check the door, replace the damaged parts, with a full body check once a year. I want my health and safety
4. Select good goods at no cost: when choosing an electric water heater, do not be greedy and buy products that are far below market prices, most of which have security risks and are responsible for their own lives and those of others
5. Do not be lazy: there will be water residue on the bottom of the boiler, as will the heater when the water is boiled, sometimes it will be clogged with water, but more of it will pile up in the guts, clean it with the conditions
