Swimming pool underwater lights: Will a swimming pool with underwater lights be equivalent to an electric shock?
2023-08-02 08:42
The hot summer is the most suitable season for swimming, even if you don't go swimming in the water, the "scenery" of the swimming pool is enough to make you ecstatic. A good swimming pool, in addition to high-quality water, beautiful environment, sufficient Lifeguard and other equipment, the illumination of LED lights at the bottom of the pool will also make the level of the swimming pool much higher~
However, recently, a paragraph and a video have been frequently forwarded on WeChat:
There are rumors that this incident occurred in a residential area in Longgang District, Shenzhen:
Some netizens also said that the incident occurred in Guangzhou:
Another person claims that this incident occurred in Gui'an Water World, Lianjiang, Fujian. However, the official Weibo response of Lianjiang Police stated that no relevant police information has been received within the jurisdiction.
In the era of Personal media, "rumors" are flying everywhere, especially the content that is closely related to our daily life. So, what is the truth?
The editor searched for relevant information online and found that the popular "pool leakage" incident occurred on July 21, 2015, at a five-star seaside hotel in Vietnam, formerly known as Barbara but now renamed as Olani Resort Apartment Hotel.
Not to mention why last year's news suddenly became popular now, swimming, as the preferred sport in summer, has always been popular among young people. Imagine swimming in a swimming pool on a hot summer day, which not only ensures the amount of exercise but also prevents heatstroke. It's great. How many people took back their steps into the swimming pool when this rumor came out!
It was also found that the focus of the rumors is mainly on swimming pools with lights, while some hotels with star level or better environments only install LED lights in the swimming pools. Is there a safety hazard of electric leakage in these swimming pools? Can't we go to these tall swimming pools in the future? Can you still swim happily?
In fact, the national standard clearly stipulates that underwater lighting fixtures for swimming pools, spray pools, swimming pools, and similar places should be classified as Class III fixtures with electric shock protection. The working voltage of its external and internal lines should not exceed 12V-24V, and the DC constant current power supply is generally used for power supply, which is relatively safe.
Of course, if the installed underwater lamp process is not qualified, the sealing is not in place, or the cable is corroded by disinfectant, it will definitely cause leakage.
Therefore, relying solely on underwater lights to determine whether there is a risk of electric shock in this swimming pool is like worrying about the battery exploding while holding your phone
Water pump leakage is the most noteworthy issue
For the issue of leakage in swimming pools, there is no need to be too nervous. Swimming pools generally have three layers of protection.
The swimming pool itself is equivalent to a grounding device, which leads electricity underground. Secondly, grounding devices are installed during the construction process of the swimming pool. Additionally, the water pump itself comes with a grounding device connected to the distribution box. When there is a leakage situation, the "protective layer" will conduct some electricity underground. Meanwhile, professionals say that water pumps need to be tested before use, with an average of once every three months.
If there is a leakage in the swimming pool, the reasons can be found from several aspects. The first is the reason for the water pump, such as the machine room being relatively damp and the motor being damp; The water pipe is leaking and the motor is getting wet. The second is whether the cable connecting the underwater lamp is corroded or not properly sealed; The third is to investigate whether the swimming pool is equipped with grounding devices. The fourth step is to check the leakage protection device of the water pump. If the device is broken, it may also cause leakage.
Therefore, if you want to quench your thirst for swimming, please try to go to a venue that has obtained a safety permit from the Sports Bureau and a business license from the industry and commerce department. Because the issuance of safety permits is very strict, not only including the water quality of the swimming pool, the prevention of infectious diseases, the proportion of Lifeguard, Lifeguard 'qualifications, etc., but also the anti-skid coefficient of tiles laid in the swimming pool.
So the question arises:
Unfortunately, if you get an electric shock and become swollen, what should you do?
Why do some people in the swimming pool only feel an electric shock, while others have a serious condition. This is because the current at the leakage point needs to pass through water to reach the human body, which is far from the water pump. The resistance of the water will be higher and hinder the current from flowing through the human body. This way, even if it flows past and back, the current will be very small. But as people get closer to the water pump, the resistance of the water is small, and the current flowing through the human body is correspondingly higher.
1. When an electric shock occurs, the most important rescue measure is to quickly cut off the power supply before rescuing the injured person.
2. When cutting off the power and disconnecting the wires, rescuers should wear rubber shoes or stand on a dry wooden stool, wear plastic gloves, and use non-conductive objects such as dry wooden sticks to remove the wires.
3. Mild symptoms: those who are conscious and have autonomous breathing and heartbeat can lie on the ground, closely observe, and temporarily do not stand or walk to prevent secondary shock or heart failure.
4. Those with respiratory arrest and heart beat: lie the injured on the ground, loosen the buttons, unblock the airway, and immediately carry out Mouth-to-mouth resuscitation. If possible, Tracheal intubation and pressurized oxygen artificial respiration can be carried out. Acupuncture can also be performed on acupoints such as Renzhong and Yongquan, or respiratory stimulants such as kaempferol, caffeine, and chloramphenicol can be administered.
5. For those with Cardiac arrest and breathing: external cardiac compression shall be performed immediately.
6. For those who have stopped breathing and heartbeat: it is better for two people to perform Mouth-to-mouth resuscitation and external chest cardiac compression at a ratio of 2 to 15 during on-site rescue, that is, two times of artificial respiration and 15 times of cardiac compression. If there is only one person being rescued on site, artificial respiration and chest compressions should also be performed in a ratio of 2:15.
