## Narrative

On April 22, 2025, at approximately 6:35 p.m., an employee was working on a turnaround project. The crew was venting off nitrogen from an 18-inch pipeline into a 2-inch silencer vessel. The 18-inch pipe was pressurized with nitrogen gas at approximately 1200 psig. The silencer suddenly ruptured and its internal components were blown away. The shell of the silencer struck downward, landed on the employee's left hand due to high pressure, and lacerated the employee's left index finger resulting in amputation. The employee's left wrist was also broken.
