Oregon your the same as me
im scared witless of them , absolutly no way will i ever have one in the house, when i was 17 we had a really old one , the type that you had to run under the cold tap to release the pressure , mum was up the other end of the house and asked me to take the cooker off the stove top and de pressure it, i didnt realise that all the pressure wasnt out and unstuck the lid and about 20 lbs of boiliing stew exploded all over me , all over my chest, up my neck all over my face and over my right hand, mum got me under cold running water and dad drove us up to a hospital that dealt in burn , it was probably about 30 min drive normally my dad made it in about 15 mins , they used gallons of iced water in compresses to control the burns i was really lucky in that i didnt get permanent scaring on my face, the only sign of it now is my right side of my face is a bit more dry than the left and i have a serious freckle thing happening on my chest that never gets tanned if i go out in the sun.
sorry to hijack your thread Betty girlfriend im not much help on the pressure cooker thing
you dont have that kind of problem with the cookers these days they are very safe , now which is always a good thing
