## Narrative

EE was removing a 3/4"" bolt using a Tone SR71E Simple Torque gun. As the bolt became loose, he released the trigger and reached in to remove the bolt while the gun was still spinning. His left thumb became pinched between the torque reactor bar and the steel beam. His basic reaction was to pull his thumb free. As he did, the pinched condition caused his thumb to be injured.
