I purchased one recently as I wanted to get over the fear I had.
Long story short, when I was young my mum was boiling a cabbage in a pressure cooker, one of the whistling ones. We were all in the living room watching the wrestling (think Big Daddy and Giant Haystacks) and the whistle stopped. No one moved until there was an almighty bang and everyone ran to the kitchen. The whistle/regulator had jammed I guess and the pressure had got too much and the resulting pressure had forced the regulator/whistle out the top of the lid and sent it up and through the ceiling in the kitchen and up through the floor of the neighbours upstairs. The Cabbage was next and was dripping from the ceiling. The entire cabbage left through a 1cm hole and was dripping from the 10ft ceiling in the house.
Worst. Smell. Ever.
