Are there any things you can do to help prevent accidents with these?
I used to use a pressure cooker to cook soup but I hardly use it nowadays since I switched to using a slow cooker.
To prevent accidents using a pressure cooker, you can cover that steam outlet with a piece of damp cloth so that when you turn the dial to release the pressure, it's not so scary.
I am not sure how the pressure cooker explodes though. Sorry to hear about that.
