And then this can happen as well.
You have a documented pressure of 12 psig and you modify the pressure vessel by introducing a manway without calculations and test that at 4 psig.
Incident occurred at 8 psig.
Has that been pressure tested at 12 psig, this fatal incident could have been avoided.

No calculations performed at all for the manhole installed tells us that there might have been no change review done.
