SC - Dangers of pressure cookers

[WyteRayven at aol.com]

I have always been pretty leary of pressure cookers. I havent actually used them, but I have been considering getting one. 

However, after reading the stories and warnings about them the last couple of days, I have to wonder how safe are they to use? 

Are they really that dangerous, or are they fairly safe as long as you follow common sense?
