How often these injuries happen
OSHA recorded 170 severe cases involving mechanical parts over the last decade. Amputations are the most frequent injury type, often resulting from sudden equipment failure or unexpected movement during maintenance.
These injuries disproportionately impact your fingers, which account for 56% of all reported cases. The permanent nature of these injuries often requires extensive surgery and long-term rehabilitation.

Check My BenefitsHow these injuries happen
Injuries involving mechanical parts typically occur when you are struck by falling components or compressed between running equipment and stationary objects. These incidents often happen during maintenance or repair, where unexpected energy release or shifting loads catch you off guard.
| Cause | Incidents | |
|---|---|---|
| 1 | Struck by falling object | 68 |
| 2 | Compressed between running equipment and other object(s) | 33 |
| 3 | Struck by propelled object or substance | 14 |
| 4 | Caught or wedged between objects— nonrunning | 9 |
| 5 | Overexertion while materials moving by hand | 8 |
| 6 | Struck by suspended or swinging object | 6 |
| 7 | Struck by propelled, falling, or suspended object— unspecified | 4 |
| 8 | Caught, entangled in running powered equipment— normal operation | 4 |
Where injuries happen most
Manufacturing accounts for 36% of all mechanical part injuries, as you frequently interact with high-torque motors and complex gear systems. These environments require strict adherence to energy control procedures to prevent accidental activation during service.
Real cases like yours
Common patterns in these incidents involve you performing maintenance on motors, gearboxes, or conveyor systems when equipment unexpectedly shifts, releases pressure, or moves. If your injury occurred during a similar maintenance task or due to a mechanical failure, an attorney can help you review the specific circumstances of your case.
| Year | State | Industry | Incident summary | |
|---|---|---|---|---|
| 2025 | TX | Manufacturing | "A subcontracted engineer was advising maintenance how to make a modification to the embossing roll system on a new line. Maintenance was bringing the motor and gearbox down with a crane. The load shifted when it was a few inches from the ground. The engineer went to catch/maneuver the gearbox and the fingers on his left hand were crushed between the I-beam base of the gearbox and the concrete floor. A finger was amputated." | |
| 2025 | MN | Transportation & Warehousing | "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." | |
| 2025 | TX | Health Care | "An employee was on the roof of the facility working on a kitchen exhaust fan hood to identify the source of a vibration. He manually moved the propeller and shaft to check for play in the bearings. His left hand slipped and his little finger became caught between the motor pulley and belt. The employee's weight shifted onto the propeller and caused the pulley to rotate, resulting in partial amputation of the distal phalanx of his little finger." | |
| 2025 | TX | Mining | "During maintenance of an annular blowout preventer, air pressure was applied to dislodge a stuck internal piston. The piston ejected and struck an employee's left bicep, causing a laceration and a fracture." | |
| 2025 | OH | Construction | "An employee was lifting a hydraulic trailer gate for an asphalt roller when a spring in the lift mechanism broke and struck the employee's chest. The employee sustained blunt force trauma to the chest requiring hospitalization." | |
| 2025 | TX | Manufacturing | "A maintenance employee was changing a shaft on a piece of equipment that had been isolated for repair. While positioning the shaft into place, the shaft fell approximately two feet and pinched the employee's left index finger. The employee suffered a partial amputation of the fingertip without bone loss." | |
| 2025 | ND | Manufacturing | "An employee was loading a motor onto a trailer when he struck his left elbow against the radiator. His elbow was lacerated and became infected, resulting in hospitalization." | |
| 2025 | OK | Retail Trade | "An employee was on a lift, helping a technician with an overhead pull-up door. The spring was being loosened, and when the tension was released, the spring came out and struck the employee on both arms. The employee sustained a compound fracture, bruising to both arms, and a laceration to his right forearm. The employee required hospitalization and surgery." | |
| 2025 | IL | Transportation & Warehousing | "An employee was removing a power assembly from a locomotive engine using an overhead crane. The power assembly became stuck, and two 1-inch lifting bolts failed as the crane continued to apply lifting pressure. This cause the power assembly to come back down and crush the employee's right hand against the engine housing. He suffered two broken bones in the hand, as well as tissue and ligament damage, and was hospitalized." | |
| 2025 | VA | Professional Services | "An employee lifted a gearbox from one shipping container to another. The employee sustained a ruptured hernia and required surgery." |
