Let's say the shop is noisy and/or the bandsaw is unusually quiet. And that the job involves doing the same cut or cuts on multiple workpieces that arrive in a bin that's behind the saw operator. So you cut a part, put the part in the output buffer, turn around to get another part, turn back to the saw... lather rinse repeat. Maybe you need to walk over somewhere to get more parts. Do you turn the saw off after every part, only to turn it back on again in a few seconds?
Safety first, I always say. But what's safe in some situations isn't in others. How about one of those red rotating (or nowadays LED strobe) beacons mounted up on top of the saw, on when the saw is on? That would be hard to ignore when leaving the room.
