The shooter and everyone in the shooting area should wear safety glasses when a gun is being handled (even if it's unloaded). Remember to remove all pets from the area, as rebounding ammo can hit them, too. Never shoot steel BBs at hard objects (including metal targets) or water, as that increases the chance of ricochet.
