<human>: TIFU I work at a factory that makes Bellevilles, which are metal discs ranging from small to very large we store them in large barrels, so today I'm helping my boss move some bins in the machine room and he was on the Fork lift, trying to get a barrel on the forks and he says grab that barrel and pull on it so it will balance on there and I can lift it and me being an idiot grab the barrel without thinking and without gloves and pull as hard as I can sending the serrated edge of the barrel directly through the middle of my index finger. Now I don't normally bleed much however tonight after I cut my finger Immediately ran to the bathroom to wash the blood away with my boss behind me and its just pouring blood everywhere. I have never bled like that before so my boss trys his best to stop it and is only able to succeed by using an entire roll of gauze and taping it really tight so he can get me to the ER. Luckily it wasn't crowded and I got stiched up pretty quickly but now I can't use my left hand for at least 7 days.

Can you succinctly summarize the text in 1-3 sentences?
<bot>: sliced open finger at work because I forgot to wear my gloves, ended up with stitches and not being allowed to use that hand for at least a week.
