Would help if wind not gusting.coming from a mining industry backgrounds a risk matrix takes 2 to 3 months to develop with the entire teams input and safety mitigation strategies flowing into procedures. This is presented to the board for further assessment and "acceptance" or "rejection" of activities where risk remains high.
You'd suggest given the number of "explosions" and "wind take off" of these blow up toys, that the products don't have built in solutions. ie if the wind exceeds 25km a wind alert immediately starts to deflate the equipment in a controlled manner after a 60 second alarm. Similar automated controls on the anchor points and anti explosion protection.
It would increase costs but at the end of the day, you kill kids if things go wrong........and they do go wrong.
Sudden gusts can come out of nowhere and as another poster suggested wind direction change likely culprit, often gusts happen when wind changes.
Anchoring should be able to cope with a sudden gust. If pickets, totally unacceptable IMO.
Tragedies happen but this was avoidable which makes it all the worse.
