Protecting your fingers

I would love to see some kind of a guard to protect little fingers from being shredded!

Take care with Bigger fingers as well, please.!!!

Foe a Fablab we made a handpowered shredder with a straight rectangle input.

You make a extra part, a square piece af wood, fitting in the hopper, fit a stick or piece of tube on there. So you can push the product in the shredder. no need to put your hands in the hopper……

i thought about this, in order to make the machine safe according to regulations and get it CE marked. I think one ‘solution’ would be make a hopper big enough so that you can’t reach the shredder if you put your arm in it…
Guards would need to be big enough so that plastic can get in
