Look at the papers

According to "Regulations on Hygiene Management in Public Places", "Detailed Rules for the Implementation of Regulations on Hygiene Management in Public Places" and other laws and regulations, the operators of swimming pools need to publicize the hygiene license, annual inspection report and hygiene reputation grade mark in the eye-catching position of swimming pools.

Operators of swimming places must obtain the hygiene license of public places before they can open their business to the outside world, and should show their business license and accept social supervision.

Before entering a public swimming pool, consumers should pay attention to whether the public health permit and the health certificate of employees are publicized in a conspicuous place in the swimming place.


Distinguishing water quality by "looking, smelling and asking"

First look: before entering the swimming pool, you must first look at the color and transparency of the water. In a swimming pool with good water quality, if it is covered with white porcelain, it will show bright light blue; If there are light blue tiles, it is dark blue; The pool water must meet the crystal clear conditions, depending on whether there are particles floating on the water surface, whether there is precipitation at the bottom of the pool, and whether the sprayed foam can dissipate within 15 seconds.

Second smell: you can smell the faint chlorine gas close to the water surface, indicating that the residual chlorine content is basically qualified. If you feel pungent and difficult to adapt, it means that the content of residual chlorine has exceeded the standard, which will cause harm to your body.

Three questions: Ask the staff about the replacement time, frequency and test results of the pool water, as well as the daily maintenance measures.

Four cuts: Feel whether there is skin discomfort in the pool water with your hands. People who often swim can feel the softness and hardness of the water. Feeling "soft" indicates that the water quality is excellent, feeling "hard" and astringent, even itching and pain, and the water quality may be poor.


Look at the sanitation facilities

See if the swimming place is equipped with dressing rooms, shower rooms, toilets, closed garbage bins and mechanical ventilation facilities that meet the hygiene requirements.

Check whether the water temperature, residual chlorine concentration, pH value and other indicators of the swimming pool on that day are qualified through the electronic bulletin board or text bulletin board of the swimming venue.

Tips for swimming health in summer


Swimming equipment and wearing swimming glasses can also reduce the direct contact between the water in the swimming pool and the eyes.

Summer is the high incidence of pinkeye, which is transmitted through contact. If a patient swims in a swimming pool, it may spread inflammation to other swimmers. The residual chlorine in swimming pool water with a certain concentration can effectively inhibit the reproduction of bacteria and prevent the spread of diseases. However, if the concentration of residual chlorine is too high, it will also cause harm to eyes.


Control the swimming time, generally within 2 hours.

Because skin diseases and other germs have to stay in the body for a period of time before they can be transmitted to the body, swimming time should not be too long, and it is best to control it within two hours. Finally, thoroughly washing the whole body with clear water after swimming can wash away pathogenic microorganisms that may pollute the skin and reduce the risk of skin diseases.


Reduce touching the public goods in the swimming pool, prepare towels and slippers by yourself and store them in the cupboard.


Pay attention to your own health and seek medical advice in time.

If you find yourself with skin damage or skin diseases, try not to go to the swimming pool in order to avoid infection or aggravate skin diseases. If you feel unwell, such as stinging eyes and skin, you should leave the swimming pool in time and clean the residual pathogenic microorganisms and disinfectants.


Replenish water before and after swimming.

You will sweat when swimming, but because your body is wet, you often can’t feel the loss of water in your body, resulting in dehydration. Nutritionists suggest drinking 600 ~ 800 ml of water before swimming, and replenishing water in time after swimming.
