Just so you will know your fears are justified here is a video of ONE of Octane's misadventures. The beginning of escape signs started to be noted here and I'll not link you to the final outcome but he did ultimately escape because I was careless (no fault of the tank lid) and ultimately died because of the exposure.
Unfortunately a really funny video of Kalypso trying to escape is no longer available on Photobucket (they have so made that site terrible and IMO have gone from best to worst with their attempts to become financially stable).
