Health and safety rules were blamed when a panto stopped throwing out sweets to the audience. In fact they were worried about the cost of compensation if anyone got hurt.
If you're unsure about an event you're organising, you might want to talk to your insurer to check that you've got the right cover and you've managed any risks effectively. It can help to make sure that trivial risks don't cause too much concern.
Realistically, if a panto throws out sweets the chances of someone being seriously hurt is incredibly low. It's certainly not something HSE worries about - as far as we're concerned, this is a case of 'Oh yes you can!'
