Swimming pool water leakage accident spread wildly on the internet
In this video, we can see a middle-aged woman crying by the pool, and then two workers in orange clothes pull a little girl in a yellow bathing suit out of the water and put it on the grass for cardiopulmonary resuscitation. According to the text forwarded by this video, a swimming pool leaked in a residential area in Shenzhen, and reminded everyone that "it is summer, pay attention to safety. People with underwater lights in the swimming pool must not get into the water, and be alert to leakage! "
The reporter of Huashang Daily found that Weibo, the street of the residential area mentioned in the video on June 24, responded that the swimming pool in the residential area has not been opened yet, and no such incident has occurred. On June 25, a netizen posted that in July last year, a five-star seaside hotel named Aunila Holiday Apartment Hotel had a "swimming pool leakage" incident, because the underwater lighting leaked electricity. By comparison, we can see that the photos of online hotels are consistent with the environment in the video.
How to ensure the safety of underwater landscape lights
On July 1 day, the reporter from Huashang Daily visited and inquired about many swimming pools in Xi 'an, and found that there were not many swimming pools with underwater lights. In addition to a one-star hotel and a water park in the western suburbs, many swimming pools in Xi 'an have no underwater lights.
There are no underwater lights in the swimming pools of several star-rated hotels in Qujiang New District, but the reporter saw underwater lights in the open-air swimming pool of a certain district in Qujiang New District.
"Now the circuit is disconnected." Wang, the squad leader and senior electrician of the residential property engineering department, said that the residential area is now in the renovation stage and the open-air swimming pool is not open. In order to avoid unnecessary trouble, the circuit has been disconnected. In the future, the swimming pool in the community will be officially opened to the public, and the underwater landscape lights may light up.
Wang said that underwater lighting is mainly for beauty, and the state has a set of strict industry norms to ensure safety. The national standard for safe voltage is 36 volts. In winter, people wear sweaters, and sometimes static electricity can reach this level. When this voltage passes through the human body, the human body will not feel the reaction. Usually, 220-volt alternating current is reduced to 36 volts through an isolation transformer, which becomes the lighting power supply for underwater landscape lights. In addition, the power terminal should be equipped with a leakage protector. Once a short circuit occurs in water, the leakage protector will work within 0.0 1 sec.
