Is the swimming pool water clean?

The weather is hot in summer, and many people like to stay in the swimming pool all day long. This not only keeps you from getting hot, but also makes your body feel comfortable. Although staying in the swimming pool in summer is good, if the water in the swimming pool is not clean, it will affect your health. In fact, if you want to know whether the water in the swimming pool is clean, it is best to choose some more professional and large-scale swimming pools to swim.

How to judge whether the swimming pool water is clean?

1. Are the walls and bottom of the swimming pool smooth and free of dirt? Is there a drainage ditch around the pool? Are there water circulation, purification and disinfection equipment that can operate normally? Are there changing rooms, shower rooms and toilets? Are there simple first aid medical equipment or a medical room? Are anti-slip mats laid around the swimming pool?

2. Check whether the water is clear and whether there is any dust or debris floating on the water surface. At the same time, if the residual chlorine content in the pool is normal and the water quality is up to standard, the water in a swimming pool paved with white tiles will appear bright light blue, while the water in a swimming pool paved with light blue tiles will appear dark blue. If the water is white and slightly turbid, it may contain excessive bacteria.

3. The pool water that meets the hygiene standards is crystal clear and you can easily see 20 meters away from the pool. If there is no sediment on the bottom of the pool, the foam in the pool water will dissipate within fifteen seconds, which indicates that the water in the pool is changed frequently and is relatively clean. If there are not many swimmers and you cannot see more than 15 meters away in the water, you will generally fail.

4. When you walk past the foot washing pool, you should be able to smell the distinct chlorine smell coming from the foot soaking pool; you can smell a faint chlorine smell in the swimming pool water when you are close to the water surface. If the smell is obviously pungent, it means that too much disinfectant has been added to the swimming pool water. If the water is even choking, it may exceed the standard or the venue may not be well ventilated; if the water has a bad smell or a sewer smell, the quality is definitely unqualified.

5. People who swim frequently can feel the "softness" and "hardness" of the water. If it feels soft, it indicates the water quality is good. If it feels "hard", "astringent", or even itchy or painful, the water quality may be poor.

What etiquette should you observe when swimming in a pool?

1. Before entering the swimming pool, consciously shower and disinfect your whole body and soak your feet to disinfect, develop good hygiene habits, and avoid sweat, bacteria, etc. from polluting the water quality. Spit snot and saliva into the drain beside the swimming pool, not into the swimming pool. You are not allowed to rub mud, pee, or play in the swimming pool.

2. Choose an area that suits you and swim along the right side of the waterline at the bottom of the pool according to the rules. Do not swim or cross waterways to avoid disturbing others. When joining a lane, slide in from the corner of the lane first. Do not dive into the lane, and do not stay in the middle of the lane.

3. When following, it is best to keep a distance of more than 5 seconds. If someone touches your feet, he may be trying to overtake you. You can move to the side of the waterway and give him the middle part to overtake. In the swimming pool, it is inevitable to kick or bump into others. Take the initiative to say sorry to them.

4. Do not dive in public swimming pools. It is indeed very exciting to dive close to the bottom of the pool, but it is actually very dangerous. Once you are kicked by someone on the water, you can easily drink water or choke on it, and you are in greater danger than those on the water.

5. Try not to overtake. Because when you overtake someone in the same lane, first of all, you are likely to collide with the person coming from the opposite direction, and secondly, you may also bump into the person you are about to overtake. It is recommended to wait until the former swims to a certain position before starting to avoid overtaking in the lane. If you really need to overtake, first confirm a safe overtaking distance and use freestyle to overtake quickly. Do not use breaststroke to avoid kicking the person being overtaken.

6. Try not to swim butterfly stroke. Butterfly stroke is the swimming style that occupies the most lanes, especially when the upper limbs are out of the water to paddle, the effect is very shocking. If you are not sure that there is no one swimming towards you from the opposite side, it is best not to take the risk of butterfly stroke.
