Good idea. For a lot of things that rotate, especially large or fast, never good idea to "stand in the plane of rotation" about 90* to shaft axis when things are spinning.
This goes for lathes, lawnmowers, prop planes, turbines/jets, etc. When things come loose or fly off, they go out in direction of plane of rotation.
