Looking at the nature of the burns in the photos, I think what got wet must  have been the 220V mains side of things, or the charger itself was full of water and bridged internally from input to output.  A long USB lead to a proper charger in a socket would not do that.


Equally the advice has to be that you should not handle things connected to the mains while you are wet, it sounds like a very near miss.

This type of incident belongs on T*itter, it will be repeated Ad infinitum, some don't recognise the obvious danger but how is it communicated and monitored?. By education, by alarms on the presence of electrical fields and warning notices inside such places, (but who will accept legislation for homes?, and there are some who would just ignore it anyway). Just another example of a suchlike incident but see https://www.dailymail.co.uk/news/article-1198470/Young-mother-electrocuted-live-tap-ran-bath-familys-new-home.html

2 things come to mind, regards the spa situation,

along the lines of hit them/ the investor(s) where it hurts - financially (or at least risk wise).


1) Does the management wish the cost of shutting down the pool, to clean the filters and other connected bits from a Lithium (which we know loves to play very excitedly with water) battery that decided to leak. The powdered form may / may not cause a local fire but could be argued to cause a reactive problem.

after all, not all phones are waterproof / are sealed.... and even some modern unable to change the battery ones are only 1m depth or rain protected.

It may not be as big a real danger, but let's not let a few proof of facts get in the way, lithium may have been a medical treatment in the past, but you don't wish to indulge today. ... risk,concern and expense are the operative words.


2) As noted, the management has not policed or apparently taken any action to enforce their policy, so if anyone's 'personal' picture ended up in pubic / circulated, expect to be included in any legal claim - they will have bigger insurance after all. Plus once it becomes known that people are not safe in a place 'expected to be safe' from photography then how many members will not wish to come & wish a refund / not join - the reputational damage. Clubs have enough competition without that added, all for want of watching for phones in visible use, removal/  suspension of membership (so they are allowing the activity in order to keep 1 member, but risk losing many more ?).


That might mean writing to the owners/owning Company rather than the local management, to express your 'concern' on your and their behalf.. Go to the top... 'in case' it is is happening elsewhere in their chain also. A clear directive of expectation and enforcement policy from the top is 'obviously' needed - so maybe enquire what the enforcement policy is ? as it does not appear to be being carried out or effective based on your (and your friends) observations.


Has the local management been formally informed (letter/email) and done nothing yet ?

Not that that would be necessary, as the situation is clearly known (or should be (*)) and not being (sufficiently) challenged despite the official policy.

(*) just because there have been no formal complaints.. .if you are aware, so should they.
