How much compensation could I be entitled to for getting my finger crushed at work?

[Franny]

I was working in a warehouse and recently had an accident that was not my fault.
A heavy item that had not been stacked on the shelves properly and it fell and crushed my finger on the metal shelf.

I never had any training from my employer and they had poor health and safety, can I claim?
How much compensation for a finger crush?
