Our foreman was using an electric impact wrench to remove the nuts off the retaining bolts to a tap changer on a substation transformer. When a nut got stuck inside the driver, he tapped it several times on the concrete then stuck his right index finger into the driver to wiggle the nut and free it. As he was doing this, he hit the trigger and drove the nut past the second joint of his finger. By the time they figured out how to cut the nut off his finger, the lack of blood past the nut ended up costing our foreman his finger.
