## Narrative

An employee was using an impact gun to remove a nut from a pneumatic cylinder during the disassembly of a test cell. When the gun made contact with the nut, residual pneumatic pressure caused the cylinder to release. The employee's left hand was pinned between a rod end of the cylinder and the rod end plate. The employee was hospitalized and had surgery for a hematoma.
