Unless of course its within a house you own, then do whatever you like...but even then I'd only utilize the sacks and barrels for things I wouldn't mind loosing (like ingredients, food, potions, clutter) just in case those containers reset some how. To be honest, I'm not sure how warranted that concern is, within your own home, but better to be cautious than loose 20 dragon bones and scales.
