I was about to say I didn't think anything would need that long, although just having a quick look through the drying guide that comes with it the longest I could spot was grapes to raisins takes 36 hours. I think most of the things I've done have been more like 12-14 hours.
I've always just used my phone alarm as a reminder to check it, I guess a timer might be handy although a few times I've checked things and found they need an hour or two more so unless you were doing things you'd done enough in the past to be really sure of the time a timer probably wouldn't be that much of a benefit.
I probably wouldn't worry too much about leaving them running, the heat is really low. They do also contain a small fan that I guess technically could fuse together and catch alight, but I guess just about any appliance or something like a PC can do that. That's me worming around that part of the question and saying it's not 100% safe but I wouldn't worry about it myself

. Just don't leave it right near curtains or anything else obviously flammable just in case the unlikely occurs.
