Incident date: 2025-07-10
NAICS industry code: 488210

Employees were performing maintenance operations on a railroad line when the machine experienced a load conveyor motor failure. While clearing the machine to allow for repairs, an employee pinned the left side of the swing conveyor. The operator on the right side then requested a slight bump to the left to align the right side for pinning. Once the swing was in position, the operator went to pin the right side and the chain tensioner failed, resulting in an abrupt release of the swing chain. The chain snapped back and struck the operator s right hand, resulting in a 1-inch laceration and a fractured fifth metacarpal. The employee was hospitalized and required surgery on the hand.
