Worst "injuries" I've had on jobs was exposure to HF due to some db not cleaning up his mess. Fortunately I immediately flushed my hand and put Calcium gluconate on, but still a stressful 24 hours since you almost don't know until your hand becomes rubber from your bones getting eaten or cardiac arrest. Also got a glass bead in my eye once while blasting metalization plates since that company didn't provide safety glasses. When I returned to work at that place I was fired for allegedly sleeping on the job. Ended up being a blessing though, turned out they weren't paying people's health and life insurance, just stealing their premiums, ended up closing without notice, leaving people without thousands in owed pay and hundreds to thousands in medical bills.
