As it's an ale you don't need to lager, so yes, you can leave it at room temp while you're brewing other stuff (providing your place doesn't get stupidly hot). It won't go bad and as for the explosion concern, even if you did fridge it fermentation could continue (albeit slowly) and they may still explode. If you're really worried about bombs, do as Pete said and recap 'em.
Does this mean literally popping the tops and recapping the beer? And this wont end in flat beer at point of intended consumption, some weeks or a month later???
Sounds logical but I can't help but think about bottles of opened coke which ultimately go flat, no matter how tight the cap is on...
