You would have to leave the bed heated for extended periods of time so that the print doesn't pop off.
I think leaving a bed heated for 48 hours to be able to complete a 30 hour print is more dangerous.
In my mind, just like charging lipos, keep the printer in a safe area (mine sites on a granite slab) away from living quarters (mine is in the garage) and protect yourself with a modern home (fire sprinklers in every room).
Any appliance can go up in flames... it is a risk we take in a modern world.
That having been said, the warning that Carl gives is valid, and it printing can be avoided while you are away/asleep, I think that is the safer way to go.
scobo, that mount rocks!
