You can't have any light at all for any common film type. I'm not sure what size film you're dealing with, but normally you'd load your film in a changing bag, not a darkroom. You wouldn't use a darkroom to process film.
With printing, each paper type will have a recommended safelight variety, but my experience (thirty years ago) was that most b&w papers were pretty tolerant for short exposure times.
