Are hamster balls safe occasionally?

Hi, I want to let me chinnies run around me in my room, but my parents are against having them loose in there. In addition to playtime, is it alright to let them run around in a ball for a little? I want to let them play in my room while I work. I understand that hamster balls are unsafe, so I wouldn’t do it often.
Thanks
