Well, wrong tool presentation, Wrong tool in my opinion, wrong speed, wrong drive should be large spikes or faceplate, no safety at all.
It worries me that social media is full of videos with pieces flying out the lathe and you get comments accepting it as something that happens. A piece of wood should not come out the lathe, if it does there is a reason and it is avoidable.
The way to learn safety is not by your mistakes but before so you can avoid them.
