Your logic of "it's safe because it hasn't happened to me" is very bad.
Just because one can go golfing during a thunderstorm and not get struck by lightening doesn't mean that it's a good idea, or that it'll never happen to them.
There's a reason groups like OSHA prohibit PVC from being used in any pressurized gas applications; rules like that just don't spring out of thin air. Obviously enough people over the years have gotten seriously hurt or killed from exploding PVC shrapnel, that it was deemed a serious enough safety issue to ban it.
