[Cthulhu_]

It's possible, but that doesn't mean it should be made impossible. Anecdotal but I've not heard of any "child falls from playground climbing thing and dies" stories. Not from the ones you describe anyway:

There was an 11 year old that died last year, but that was in a professional climbing hall; I'm not sure what happened but they were supposed to be secured. But that was a 13 meter drop, and the fifth incident like that in a 30 year timespan.

And there was a 4 year old that died after falling three meters from a bouncy castle in an indoor play area; the owners of the venue were pulled up on the unsafe conditions in 2013, but due to various mistakes they only got the report nearly a year later and did not remove the dangerous thing until the child fell off and died.
