Though there was no big bang this has happened to me... and others.
Brushed up against the stove controls and accidentally turned on a burner.
Since the RV cooktop is not an "Auto-light" type... Gas escaped.
Nose detected and valve closed no boom.
HOWEVER.. It is written: Smoking can kill you.. Imagine that due to smoking the nose is disabled, does not smell well (Do a good job of smelling things) and I go to light up my next cancer stick KA-BOOM.
Reason not even on the list WHY I do not smoke.. but it is a good reason.
