swimming pool , bath pool , wading pool , or rowing pond is a structure designed to hold water to allow swimming or other recreational activities. Ponds can be built on land (pond on land) or built on land (as free standing construction or as part of buildings or other larger structures), and is also a common feature aboard ships and cruise ships. Ground pools are generally constructed from materials such as concrete, natural stone, metal, plastic or fiberglass, and can be custom-sized or custom built or sized, the largest of which is the Olympic-size swimming pool.
Many health clubs, fitness centers, and private clubs, such as the YMCA, have a pool that is mostly used for sports or recreation. Many cities and towns provide a public swimming pool. Many hotels have pools available for guests to use at their leisure. Educational facilities such as universities typically have pools for physical education classes, recreational activities, recreational or competitive athletics such as swimming teams. Hot tubs and spas are pools filled with hot water, used for relaxation or hydrotherapy, and are common in homes, hotels, and health clubs. The special pool is also used for diving, special water sports, physical therapy as well as for the training of coast guards and astronauts. The pool can be heated or not heated.

History
The "Great Bath" on Mohenjo-Daro's site in modern-day Pakistan is most likely the first swimming pool, dug during the 3rd millennium BC. The pool is 12 by 7 meters (39 by 23 feet), lined with bricks, and covered with a tar-based sealer.
Ancient Greeks and Romans built artificial ponds for athletic training in palaestras, for nautical games and for military training. The Roman Emperor had a private pool where fish were also stored, so one of the Latin words for the pool was piscina . The first hot spring pool was built by Gaius Maecenas of Rome in the 1st century BC. Gaius Maecenas is a rich Roman ruler and is considered one of the first art patrons.
Ancient Sinhala built pairs of swimming pools called "Kuttam Pokuna" in the kingdom of Anuradhapura, Sri Lanka in the 4th century BC. They are decorated with steps of stairs, punkalas or potted abundance, and scroll design.
19th century
The swimming pool became popular in England in the mid-19th century. In early 1837, six indoor swimming pools with skateboards were in London, England. The Maidstone Swimming Club in Maidstone, Kent is believed to be the oldest surviving swimming club in England. It was formed in 1844, in response to concerns over the drownings on the Medway River, mainly because the potential saviors would often drown because they themselves could not swim for safety. The club is used for swimming on the Medway River, and will hold a race, diving competition and water polo match. South East Gazette July 1844 reported an aquatic breakfast feast: coffee and biscuits served on a raft floating in the river. The coffee is kept hot on the fire; club members had to tread water and drink coffee at the same time. The last swimmer managed to reverse the raft, becoming entertainment for 150 spectators.
The Amateur Swimming Association was founded in 1869 in England, and the Oxford Swimming Club in 1909. The existence of an indoor bath in a rocky area on Merton Street may have persuaded fewer members of the water brigade to join. So the baths gradually became swimmers, and the bathing pool became a swimming pool. In 1939, Oxford created a public indoor swimming pool in Temple Cowley.
The modern Olympics began in 1896 and included a swimming contest, after which the popularity of the swimming pool began to spread. In the US, the Racquet Club of Philadelphia clubhouse (1907) offers one of the world's first modern underground swimming pools. The first swimming pool that went overboard aboard a ship was installed at the Adriatic White Star Line in 1906. The oldest known public swimming pool in America, Underwood Pool, is located in Belmont, Massachusetts.
Interest in competitive swimming grew after World War I. Standards improved and training became important. The home swimming pool became popular in the United States after World War II and the publicity given for swimming sport by Hollywood movies like Esther Williams' Million Dollar Mermaid made the desired status symbol. Over 50 years later, a home or residential swimming pool is a common sight. Some small countries enjoy a thriving swimming pool industry (eg, New Zealand pop 4,116,900 [Source NZ Census March 7, 2006] - holds a record in a per capita pool with 65,000 home pools and 125,000 spa pools).
The two-story white concrete pool building consisting of horizontal cubic volume built in 1959 at Royal Roads Military College is located in the Canadian Historic Site Registry.
World record
According to Guinness World Records, the largest swimming pool in the world is the San Alfonso del Mar seawater pool in Algarrobo, Chile. It is 1,013 m (3,323 ft) in length and has an area of ​​8 ha (20 hectares). At its depth, its depth is 3.5 m (11 ft). Completed in December 2006.
The largest indoor wave pool in North America is at the West Edmonton Mall and the largest indoor pool is located at the Neutral Buoyancy Lab at the Sonny Carter Training Facility at NASA JSC in Houston.
In 2014, the Y-40 swimming pool at the Terme Millepini Hotel in Padua, Italy becomes the deepest indoor pool, certified by the Guinness Book of World Records The Nemo 33 recreation diving center near Brussels, Belgium previously holds the record until Y-40 finishes.
The Fleishhacker Pool in San Francisco is the largest outdoor hot spring pool in the United States. Opened on April 23, 1925, it was measured 1,000 times 150 feet (300 times 50 m) and so large that the lifeguards needed kayaking for patrols. It was closed in 1971 due to low patronage.
In Europe, the largest swimming pool opened in 1934 in Elbl? G (Poland), providing a water area of ​​33,500 square meters (361,000 sq., Ft).
One of the largest pools ever built was supposedly created in Moscow after the Soviet Palace remains incomplete. The foundation of the palace was converted into Moskva Pool's open swimming pool after the de-Stalinization process. However, after the fall of communism, Christ the Savior of the Cathedral was rebuilt on the site between 1995 and 2000; the cathedral was originally located there.
The highest swimming pool is believed to be in Yangbajain (Tibet, China). The resort is located at 4200 m AMSL and has two indoor pools and one outdoor pool, all filled with water from hot springs.

Dimensions
- View: #Competition building (below)
Length: Most swimming pools in the world are measured in meters, but in the United States, pools are often measured in feet and yards. In the UK most of the pools are calibrated in meters, but older pools measured in meters still exist. In the US, the pool tends to be 25 yards ( SCY - short path), 25 meters ( SCM -all it) or 50 meters (long lane). The US and NCAA secondary schools host a short course competition (25 yards). There are also many ponds 33 1/3 m long, so 3 length = 100 m. This pool dimension is generally used to accommodate water polo.
USA Swimming (USA-S) swimming in both metric and non-metric pools. However, international standards are meters, and world records are only recognized when swimming in a 50m (or 25m for a short course) swimming pool but a 25-yard pool is very common in the US. In general, the shorter the pool, the faster the time for the same distance, because the swimmer gets the speed from pushing the wall after every turn at the end of the pool.
Width: Most European pools are between 10m and 50m wide.
Depth: The depth of the swimming pool depends on the purpose of the pool, and whether it is open to the public or just for personal use. If it is a relaxing, private, relaxing pool, it might go from 1.0 to 2.0 m (3.3 to 6.6 feet) deep. If a public swimming pool is designed for diving, it may slope from 3.0 to 5.5 m (10 to 18 feet) on the deep end. Children's play pools can be from 0.3 to 1.2 m (1 to 4 feet) deep. Most public pools have different depths to accommodate the needs of different swimmers. In many jurisdictions, it is a requirement to show the depth of water with a clearly marked depth affixed to the pool wall.
Type
The pool can be inside or outdoors. They can be of any size and shape, and inground or on the ground. Most pools are permanent fixtures, while others are temporary, foldable structures.
Private pool
Private pools are usually smaller than public pools, averaging 3.7 mm 7.3 m (12 ft ft-24 ft) to 6.1 m² - 12.2 m (20 ft ÃÆ' - 40 ft) whilst public pool usually starting at 24 m (80 ft). Pond houses can be built permanently, or assembled on the ground and dismantled after the summer. Private pools owned in backyards or gardens began to proliferate in the 1950s in areas with warm summer climates, especially in the United States with desegregation.
The construction methods for private pools vary widely. The main types of swimming pools in the ground are shotcrete gunite, concrete, vinyl, and one-piece fiberglass shells.
Many countries now have rigorous hedgerow requirements for private pools, which require a pool area to be isolated so that unauthorized children younger than six are unable to enter. Many countries need the same level of protection for children living in or visiting homes, although many pool owners prefer the visual aspect of swimming pools near their living areas, and will not provide this level of protection. There is no consensus between countries or countries about the requirements to fence private pools, and in many places they are not needed at all, especially in rural areas.
Children's pool
A cheap temporary polyvinyl chloride pool can be purchased at the supermarket and lowered after the summer. They are used mostly outdoors in the yard, usually shallow, and often their sides are pumped with air to remain rigid. Once completed, water and air can be removed and this type of pool can be folded for convenient storage. They are considered in the swimming pool industry as a "splasher" swimming pool intended to cool and entertain toddlers and children, not to swim, hence the alternative name of the "kiddie" pool.
Toys are available for children and others to play with pool water. They are often blown up with air so they are soft but still quite rough, and can float in the water.
Public pool
Public swimming pools are often part of a larger recreational center or recreation complex. These centers often have more than one pool, such as an indoor heated pool, an outdoor pool (chlorinated, salt or ozonated) that may be heated or not heated, a shallower children's pool and a pool rowing for toddlers and babies. There may also be a sauna and one or more hot tubs or a spa pool ("jacuzzi").
Many upscale hotels and holiday resorts have pools for use by their guests. If the swimming pool is in a separate building, the building may be called natatorium. The building sometimes also has facilities for related activities, such as a diving tank. The larger pool sometimes has a diving board taped to one side on the water.
Many public pools are rectangular in shape 25 m or 50 m, but they can be any size and shape. There is also an elaborate swimming pool with artificial waterfalls, fountains, splash pads, wave engines, various water depths, bridges and island bars.
Some swimming facilities have lockers for clothes and other items. Lockers may request a coin to be inserted into a slot, either as a deposit or payment. There is usually rain - sometimes mandatory - before and/or after swimming. Often there are also coast guards to ensure the safety of users.
A wading or paddling pool is shallow waters intended for use by small children, usually in parks. Concrete wading pools come in various shapes, traditionally rectangular, square or circular. Some are filled and dried daily due to lack of a filter system. The staff chlorinated water to ensure health and safety standards.
Competition pool
- View: #Dimension (top) and Swimming (sport) #Competitive companies
The FÃÆ' Â © dation Internationale de la Natation (FINA, International Swimming Federation) sets the standard for a collection of competitions: 25 or 50 m (82 or 164 feet) long and at least 1.35 m (4.4 m) deep. Competitive pools are generally indoors and heated to allow for year-round usage, and are easier to comply with regulations on temperature, lighting, and automated clearance equipment.
The Olympic size swimming pool (first used at the 1924 Olympics) is a swimming pool that meets the additional standards of FINA for the Olympics and for world championship events. It should be 50 by 25 m (164 by 82 ft) wide, divided into eight lanes 2.5 m (8.2 m) each, plus two fields of 2.5 m (8.2 m) on each side of the pond. The depth should be at least 2 m (6.6Ã, ft).
Water should be stored at 25-28 Â ° C (77-82 Â ° F) and lighting levels over 1500 lux. There are also rules for the color of the rope line, the position of the backstroke flag (5 meters from each wall), and so on. Pools claimed to be an "Olympic pool" do not always meet this rule, because FINA can not use the term by the police. Touchpads are installed on both walls for long-term meetings and each end for a short course.
Swimming pool can be called sooner or later, depending on the physical layout. Some design considerations allow reduction of pool resistance to make pools faster: that is, proper depth of pool, current elimination, increased path width, energy absorbing racing pathways and gullies, and use of hydraulic designs, acoustics and other innovative lighting.
Workout pool
In the last two decades, the new pool style has gained popularity. It consists of small vessels (typically about 2.5 ÃÆ'â € "5 m) where swimming swimmers are in place, either against artificial flow of artificial water produced or against the pulling of the retaining device. This pool has several names, like swim spa , swimming machine , or swim system . They are all examples of different modes of pool resistance.
Hot tub and spa pool
Hot springs and spa pools are common hot water pools used for relaxation and sometimes for therapy. Public commercial spa in the pool or sauna area at a health club or fitness center, in exclusive five-star hotel clubs, women's clubs, motels and suites. The spa clubs may have a very large pool, some segmented into an increase in temperature. In Japan, men's clubs with many spas of different sizes and temperatures are common. Commercial spas are generally made of concrete, with interior mosaic tiles. Recently with an innovative pre-shaped composite method in which mosaic tiles are tied to this shell allowing commercial spas to be fully factory manufactured to specification and shipped in one piece. Hot tubs are usually made somewhat like wine vats with straight sides, from woods like California Redwood held in place by metal circles. Soaking heads are not recommended in spas or hot tubs because of the potential risk of underwater traps from pump suction power. However, commercial installations in many countries must comply with various safety standards that greatly reduce this risk.
Spa houses are worldwide retail goods in western countries since the 1980s, and sold in specialty spa stores, pool shops, department stores, internet, and book sales catalogs. They are almost always made of acrylic sheet extruded in Perspex heat, often stained with marble-like patterns. They rarely exceed 6 m 2 (65 sq ft) and are usually 1 m (3 ft 3 in) in, limited by the availability of raw sheet sizes (usually produced in Japan). There is often a seating or relaxing system in the middle, and chairs are lean back in the usual stylish chairs. Top-end spas include various jet nozzles (massage, pulsating, etc.), Drink trays, lights, flat-screen LCD TVs and other features that make the swimming pool a leisure center. Due to its family-oriented nature, the spa house is usually operated from 36 to 39 Â ° C (97 to 102 Â ° F). Many pools are incorporated in redwood or surround wood simulations, and are called "portable" because they can be placed on the porch rather than sink to a permanent location. Some portable spas are shallow and narrow enough to be fitted sideways through standard doors and used indoors. Low power soaking heater is common with a house spa.
The first whirlpool tub became popular in America during the 1960s and 1970s. A spa is also called a "jacuzzi" in the United States since it became generic after the Jacuzzi piping component manufacturer introduced a "whirlpool spa" in 1968. The air bubbles can be inserted into nozzles through an air-venturiated venturi pump that combines cold air with hot water go in to cool the pool if the temperature rises uncomfortably high. Some spas have a steady stream of bubbles through the pool seating area, or footwell area. This is more common as a temperature control device in which hot water comes from natural geothermal sources (uncontrolled heat), rather than artificially heated. The water temperature is usually very warm to hot - 38 to 42 Â ° C (100 to 108 Â ° F), so usually the baths stay only for 20 to 30 minutes. Bromine or mineral sanitizer is often recommended as a cleanser for the spa because chlorine disappears at high temperatures thus enhancing its strong chemical odor. Ozone is an effective bactericide and is generally included in the circulatory system with cartridge filtration, but not by sand filtration due to clouding problems with cloudy body fat.
Ocean pool
In the early 20th century, especially in Australia, sea ponds were built, usually on a promontory by attaching a section of stone shelves, with water circulated through ponds with flooding from tidal or regular flood tanks on the side of the pond at high tide. It continues the pre-European tradition of bathing in rockpools with many sites currently being expanded from sites used by Australian Aborigines or early European settlers. Bathing in this pool provides security against both rough waves and marine life. There are often separate pools for women and men, or swimming pools open for sex at different times with rest for baths to climb in without fear of observations by other sexes. It is the pioneer of the modern "Olympic" pool. Variation is the subsequent development of ocean-side pools or harbors that circulate seawater using pumps. This type of pool is a training ground for Dawn Fraser Australia Olympus.
Currently there are about 100 oceanic baths in New South Wales, which can range from small ponds of about 25 meters long and "Olympic Size" (50m) to very large, such as 50 ÃÆ'â € "100m baths in Newcastle. While most are free, a number of cost charges, such as the Bondi Icebergs Club swimming pool at Bondi Beach. Although the development of the pool is chlorinated and heated, the ocean baths remain a popular recreational form in New South Wales.
Semi-natural seawater is on the central coast of New South Wales; it's called the Bogey Hole.
Infinite set
The infinite pool (also called the negative edge of the pool is lost) is a pool that produces a visual effect of water that extends to the horizon, disappears, or extends to "infinity". Often, water appears to fall into the sea, lake, bay, or other similar bodies of water. This illusion is most effective whenever there is a significant change in improvement, although having a natural body of water on the horizon is not a limiting factor.
Natural pool and pool
The natural pool was developed in central and western Europe in the early and mid-1980s by landscape designers and architects with environmental concerns. They have recently become more popular as an alternative to traditional swimming pools. A natural pool is a water body built where no chemicals or devices disinfect or sterilize the water used, and all pool cleanup is achieved purely by water movement through biological filters and hydroponically rooted plants in the system. In essence, natural pools are trying to recreate swim holes and lakes that can be enjoyed, an environment where people feel safe swimming in unspoiled, healthy, and ecologically balanced waters.
Water in a natural pool has many desirable characteristics. For example, red eyes, dry skin and hair, and gray swimwear associated with over-chlorinated water are naturally absent in natural ponds. Natural ponds, requiring a water garden to be part of the system, offer different aesthetic options and can support amphibian wildlife such as snails, frogs and salamanders, and even small fish if desired.
Pool enter-zero
A zero-in pool , also called the beachside swimming pool , is a pool that has edges or entrances that gradually tilt from the deck into the water, becoming deeper with every step, by the natural way of the beach. Because there are no stairs or stairs to navigate, these types of entries help older people, young people, and people with accessibility issues (eg, physically disabled) where incremental entries are useful.
Indoor Pools
Indoor pool is located inside, under the roof and isolated by at least three walls. Built for swimming or training purposes throughout the year, they are found in all types of climates. Since the pool room is isolated, it is unlikely the heat will come out; making it cheaper to heat than the pool where the heat will come out. Architecturally, the indoor pool may look like the rest of the house, but in terms of engineering, variables such as heating and ventilation are needed to ensure a comfortable humidity level. In addition to drainage and automatic pool cover, there are a number of ways to remove moisture in the air that comes with a wet indoor environment. Efficient dehumidification in an indoor pool environment prevents structural damage, lowers energy costs in addition to improving the room climate to make it a comfortable swimming environment.
Other uses
Swimming pools are also used for events such as synchronized pools, water polo, canoe polo and underwater sports such as underwater hockey, underwater rugby, finswimming, and diving exercises as well as for teaching diving, life-saving and scuba diving techniques. They have also been used for special tasks such as teaching water-resistant techniques to flood for aircraft and submarine crews and astronaut training. Swimming pools are clipped round, irregular, like the Nude Bowl, drained water and used for vertical skateboards.
Sanitation
The level of bacteria and viruses in the pool water should be kept low to prevent the spread of disease and pathogens. Bacteria, algae and insect larvae can enter the pond if water is not cleaned properly. Pumps, mechanical sand filters, and disinfectants are often used to clean water.
Chemical disinfectants, such as chlorine (usually as hypochlorite salts, such as calcium hypochlorite) and bromine, are commonly used to kill pathogens. If not properly treated, chemical sanitation can produce high-level disinfectant byproducts. Pool water sanitation can theoretically appear green if a number of iron salts or chloride copper are present in the water.
Acesulfame potassium has been used to estimate how much urine is discharged by swimmers into the pool. In a study in Canada it is estimated that swimmers have released 75 liters of urine into a large pond that has about 830,000 liters of water and constitutes one-third of the size of the olympic pool. Hot tubs are found to have higher marker readings. While the urine itself is sterile, its degradation products can cause asthma.
Include
Pool heating costs can be significantly reduced by using pool cover. Use of pool cover can also help reduce the amount of chemicals (chlorine, etc.) required by the pool. The outdoor pool gets hot from the sun, absorbing 75-85% of the solar energy that hit the pool surface. Although the cover reduces the total amount of solar heat absorbed by the pool, the cover eliminates heat loss due to evaporation and reduces heat loss at night through its insulating properties. Most of the heat loss in the pool is through evaporation.
The effectiveness of heating the cover depends on the type. The transparent bubble cover is the most effective, as it allows the largest amount of solar flux into the pool itself. The thermal bubble cover is a lightweight UV-stabilized floating cover designed to minimize heat loss in a heated swimming pool. Usually they are only installed in spring and fall (autumn) when the temperature difference between pond water and air temperature is the largest. They raise the pool temperature to about 20 Â ° Fahrenheit, or 11 Â ° Celsius, after being in the pool for a week. The cover bubble is usually applied and removed by being rolled on a device mounted on one side of the pool (see illustration). Includes falling after four or five years due to sun exposure, overheating in the sun when out of the pool, and chlorine attacking plastic. The bubble cover must be removed during super chlorination.
The vinyl cover absorbs more direct sunlight, allowing the temperature to rise faster, but ultimately preventing the pond from reaching a clear, high-cover temperature. The vinyl blanket is composed of heavier material and has a longer life expectancy than a bubble cover. Insulated vinyl sheath is also available with a flexible insulating layer flanked between two vinyl layers. This cover is mandatory for installation to all pools in the drought-stricken region of Australia since 2006. This is an effort to conserve water, as a lot of water evaporates and occurs.
Alternatives to continuous pool sheets include some floating disks that are deployed and removed disk by disk. They cover most of the surface of the pond and offer evaporation reductions similar to sustainable cover. Different types are available, eg opaque (for UV resistance and possibly reducing algae growth), transparent (for aesthetic), heavy and solid (for wind resistance), light and wind (for ease of handling).
- Liquid covers
Fluid cover is also an option. They use a thin layer of microscopic fluid (such as cetyl alcohol) that sit on the water surface and reduce evaporation, which is one of the major sources of heat loss and water loss. Unlike other closures, the pool can be used when the liquid cover is in place, and non-toxic materials are safe for people as well as pumping/filtering systems. Fluids should be refilled regularly (monthly or more), and may not be effective in windy areas (because the wind will dissolve a thin layer).
- Safety includes
These coverings are usually attached throughout the winter, with hooked bungee straps or springs connected to the pool deck, and are usually made in a variety of materials including vinyl or polypropylene coated or laminated. They are specially designed to stop the leaf debris from entering the pond but more importantly they also provide security for animals and small children when properly designed and installed. The custom security cover was created in 1957 by Fred Meyer Jr. of Meyco Pool Covers when he found dead animals in his swimming pool. Today's coverings are made to meet the barrier safety standards of ASTM and have made animals, people and even large vehicles out of the pool. They are not popular in warm climates, as five to ten minutes are needed to adjust/remove them, making them uncomfortable for repetitive applications and deletions.
Automation of swimming pool cover
The pool cover can be either manually, semi-automatically, or operated automatically. The manual cover can be folded and stored in an offsite location. Pool cover rolls can also be used to help roll the pool cover manually. Rolls, usually on wheels, can be rolled in or out of place.
Semi-automatic cover using motor-driven reel system. They use electric power to roll and unroll the roll, but it usually takes a person to pull the lid off when unrolling, or guide the cover to the roll when rolling the cover. Semi-automatic cover can be built into the pool deck that surrounds the pool, or can use a roll on the cart.
The automatic cover has a permanently installed roll that automatically closes and opens the pool with the push of a button. They are the most expensive option, but also the most convenient. These rolls can be run either from an external motor which requires a hole to be excavated beside the pool or using an internal motor that rotates the reel.
Some of the pool cover matches the tracks along the side of the pool. This prevents anything or anyone from entering the pool. They even support the weight of some people. They can be run manually, semi-automatically, or automatically. Safety cover may be required by the inspector for the public pool.
Winterization
In areas that reach freezing temperatures, it is important to seal the pool properly. It varies greatly between pools on land and on land. By taking steps to secure the pool well, it reduces the possibility that the superstructure will be damaged or disturbed by freezing water.
Closing vinyl and fiberglass pool
In preparation for freezing temperatures, swimming pool pipes on the ground should be emptied. The above ground pool must also be closed, so the ice does not drag the pool wall, undermine its structure. The pipe is covered with air, usually with rubber stoppers, to prevent cracks from frozen water. These pools are usually covered to prevent leaves and other debris from falling. The lid attached to the pool usually uses stretching straps, similar to bungee cables and hooks fitted to the pool. A closed skimmer or a floating device is placed into it to prevent it completely freezing and cracking. Floating objects such as life rings or basketball can be placed in a pool to avoid freezing under cover. Sand or DE filter must be washed again, with main drain plug removed and all water drained. The drain plugs on the filter pool are cleaned after the filter is cleaned. The pump pool motor is taken under the cover. Winter chemicals are added to keep the pool clean. The innovation of fiberglass composite construction, with epoxy coating and porcelain ceramic tiles has led to Pre-shape, Composite type with significant advantages over older methods; However, this also increases the sensitivity to metal staining.
In a climate where there is no risk of freezing, closing the pool for winter is not so important. Typically, thermal cover is removed and stored. Winter sunshine can create messy algae when the cover that has been left in all winter is removed. The pool properly has a balanced pH and super-chlorinated. One part algaecide for every 50,000 parts of pond water should be added, and filled each month. The pool should be filtered for one to two hours each day to keep the chlorination system automatically active.
Security
The pool poses a risk of drowning, which may be significant for inexperienced swimmers, suffering from seizures, or prone to heart or respiratory conditions. Lifeguards are employed in most pools to implement water-saving and manage the first aid needed to reduce this risk.
Diving in the shallow pool area can also cause significant head and neck injury; Diving, especially the first head dive, should be done at the innermost point of the pond, at least 2.4 m (7 ft 10 inches), but preferably 3.7 m (12 ft), deeper if the distance between the water and the board is good.
The pool also presents a significant risk of infant and under-five mortality due to drowning. In areas where public housing pools, drowning is a major cause of childhood death. As a precaution, many jurisdictions require a pool of enclosures to be covered by a fence to restrict unauthorized access. Many products exist, such as removable baby fences, floating alarms, and window/door alarms to reduce the risk of drowning for babies. Some pools are equipped with computer-assisted prevention or other forms of electronic safety and security systems.
The suspended ceiling in the indoor pool is a safe component for safety. The choice of materials under pressure should be done with caution. Especially the selection of stainless steels that do not match can cause problems with the corrosion of tense cracks.
Dress code
In public swimming pools, dress codes may be tighter than on public beaches, and in indoor pools tighter than outdoor pools. For example, in countries where women can topless on the beach, this is often not allowed in the pool, and swimsuits should be worn. For men, wearing regular shorts and t-shirts to go on the water on the beach can be considered acceptable, but the pool usually requires real swimwear or other special waterwear. Swimming with regular clothes is not only unhygienic, but can potentially weigh a swimmer if he has to be saved. In France and some other European countries, board shorts are usually not allowed for health reasons. In the Nordic countries and especially Iceland, the rules on clothing and hygiene are very strict. When diving from high boards, bathing suits are sometimes charged twice (one short inside the other) in the case of a torn outdoors suit on the water.
