I got stabbed by a dumbbell today

I’m doing seated shoulder press and I have the dumbbells up on their ends vertically so they don’t roll away and on my third set I reach down to grab them and something stabs my hand. Theres blood, women are screaming, a nearby bro faints. actually nobody else saw it but there was a little blood. looking at the dummbell I see what appears to be a staple protruding from the rubber casing. try to remove it but it’s either lodged in deep or is part of some internal structure? in any case I alerted the gym manager and got a bandaid and wrapped up the day there. it’s just not something I would have imagined could happen.
