You don't die, or explode, of liquify or anything else 'instantly' in the vaccuum of space like they do in movies.
Even without a spacesuit It is possible to live in the vacuum of space for up to 3 minutes.
So if you accidentally fell out of an airlock (I don't know how you can 'accidentally' fall out of an airlock
), you could be rescued if others are quick enough to get you.
