Playground Danger

There is soft rubber mats underneath the play area, which is good. But very close to this is a stony path.

What happens is the stones, some 3cm or so, get onto the mats so then are stationary and stick up.

I think falling onto a stone, which now has sharp edges pointing upwards, because of the rubber mat, is going to be far more dangerous than just falling onto the hard compacted mud.

So I think this setup is actively endangering life or making serious injury much more likely
