In America they all do still wear cotton clothing into swimming pools.(cotton tee shirts, shorts, boxers and underwear into the pool). In other country's around the world due to new very strict public health and safety laws, you must change into a clean speedo or a similar type of swimwear before ever entering a spa or pool. Lycra and nylon Rash tops are acceptable only if you showered with it on before entering the pool. This health and safety law was made to help stop the spread of all viral illness,contagious skin diseases you can get from an infected person in public swimming pools. When a person comes into a public swimming pool wearing clothes like they all do in the US. You have no idea how long they have been wearing them previously before entering the pool. Especially what was spat, wiped, spilled, or if the clothes they are wearing were used to dry something harmful to other people and the last time the clothes there wearing had or ever been washed. People swimming wouldn't know if the person swimming next to them had on clean or very dirty unwashed and skid marked underwear which could cause the spread hepatitis A or even genital herpes or they are covering over a very infectious or contagious skin irritation under a tee shirt. You times this risk by ten times to the amount of people who are in a pool or had been previously were swimming in the pool before you dived in for a swim. This is why public spa's and pool's have or are beginning to imposed a strict swimwear rule at public pools and you can't any longer wear cotton tee shirts, underwear or any clothing into pools.
Lightning protection as its called is generally only installed to protect tall high rise buildings or church steeples from damage by lighting strikes. The protection needs to be taken from the roof or highest object of your property to ground to discharge via a roof top fineal which points 2 ft above the roof ideally one at each corner of the roof, from the fineal are installed insulated copper tape ( 1/8 inch thick) attached to the outside of the building and firmly connected to steel earth rods (ground in USA) hammered into the ground one in each corner of the building. Generally the designer of a lightning protection system(LPS) refers to a lightning strike probability map of the area to advise of the probability of the strike and design the LPS to correctly protect all sections of the property.
cotton colors can bleed cotton fibers come loose , clogging the drains if one person breaks the rules.. everyone will you got a sunburn by not using sunscreen, or not enough NOT by not wearing cotton
You can't wear cotton because the strings fray and get stuck in the filters and pipes. It's only a little bit but over time (and many many uses) it clogs up.
Public health and safety I'd never would swim in a cesspool or ever want to end up sick while training and competing in my sport. Neither do other swimmers who use public pools or spas. This is why they no longer allow any clothing at all only a speedo or racing swimwear at my pool, You could wear a rash top like Aussie Boy mentioned it offers 30+ sun protection.
