Everything is dangerous to someone, somewhere. The answer? Ban everything...at least from schools. Then all the children will be safe. It's so obvious that I'm surprised it hasn't been made law yet. Keeping track of it all and monitoring it would also provide many useful jobs for idiots who yearn to be petty dictators and enforce complex rules and regulations upon helpless children...and that's just one of the many lucrative spinoffs to such a health and safety plan. Think of the possibilities for the legal profession...
