How often these injuries happen
OSHA recorded 39 severe incidents involving pumps over the recent reporting period. The most frequent injury type is amputations, which account for 51% of all cases, reflecting the extreme force and speed of moving pump components.
These injuries are particularly devastating because they often involve your fingers, which are impacted in 58% of all recorded incidents. The resulting trauma frequently requires complex surgery and long-term rehabilitation to address permanent loss of function.
How these injuries happen
Most pump injuries occur during routine maintenance, cleaning, or testing, with 45% of incidents involving you being struck by running powered equipment. You are often caught when a pump unexpectedly activates or cycles while you are clearing built-up material, rotating shafts, or troubleshooting mechanical malfunctions. These incidents frequently happen when safety interlocks are bypassed or fail to prevent the equipment from moving during service.
| Cause | Incidents | |
|---|---|---|
| 1 | Struck by running powered equipment— during maintenance, cleaning, testing | 17 |
| 2 | Struck by falling object | 5 |
| 3 | Struck by running powered equipment— irregular movement, kick back | 3 |
| 4 | Caught or wedged between objects— nonrunning | 2 |
| 5 | Exposure to electric arc | 2 |
| 6 | Struck by suspended or swinging object | 1 |
| 7 | Overexertion while materials moving by hand | 1 |
| 8 | Fire— unspecified | 1 |
Where injuries happen most
Manufacturing accounts for 46% of all pump-related severe injuries, as these facilities rely heavily on continuous-duty pumping systems for production. Construction follows at 23%, where portable pumps are frequently used in environments that demand constant monitoring and frequent cleaning, increasing your risk of exposure to moving pistons and pressurized lines.
Real cases like yours
Common patterns in these incidents include you attempting to clear obstructions or troubleshoot equipment while the pump is still energized or capable of cycling. Many reports describe sudden piston movement or shaft rotation that catches your hand or glove, leading to immediate and severe trauma. If any of these scenarios sound like what happened to you, an attorney can help you review the specifics of your incident to determine if employer safety failures contributed to your injury.
| Year | State | Industry | Incident summary | |
|---|---|---|---|---|
| 2025 | CO | Construction | "An employee was cleaning out a grout pump when his hand became caught in moving parts. The employee's fingers were amputated." | |
| 2025 | TX | Construction | "An employee was using an air-actuated pump to pump oil from a mill to a 55-gallon drum when the pump malfunctioned. The employee went to fix the pump when it activated and the piston contacted their left index fingertip, resulting in an amputation." | |
| 2025 | TX | Mining | "An employee was cleaning the cylinder on a 55-gallon barrel pump. While he was cleaning built-up material from under the baseplate, the piston started moving and caught his thumb against the seat. Three-quarters of an inch of the thumb was degloved; he was hospitalized, requiring surgery." | |
| 2025 | NJ | Public Administration | "An employee noticed a polymer mixer pump was shaking and went to troubleshoot it. The employee was working to rotate the shaft of the mixer pump when the shaft started and grabbed his glove. He sustained a compound fracture to the left thumb." | |
| 2025 | FL | Agriculture | "An employee was servicing a master lift station and setting up a power analyzer when an arc flash occurred. The employee sustained burns to their hand, arm, neck, and face." | |
| 2025 | NJ | Manufacturing | "The injured employee removed a front plate to clean a pump. His left hand was caught in moving parts and the employee's middle fingertip was amputated. " | |
| 2025 | MO | Construction | "An employee was pouring concrete. The hose clogged and then whipped around and struck the employee in the abdomen. The employee sustained liver damage and internal bleeding." | |
| 2025 | IL | Transportation & Warehousing | "On March 27, 2025, a truck driver had pulled up to a riser to load fuel into their truck. The driver was pulling down on the loading arm at the fuel terminal, or lifting the fuel loading arm when they felt pain in their abdomen. The employee sustained a hernia." | |
| 2025 | NJ | Other Services | "Three employees were removing a vertical turbine pump assembly, consisting of an electric motor, pump head, and submerged bowls. After removing the motor and staging it for transport, the team began lifting the remaining pump system and disconnecting the pump head from the bowl assembly. The pump head was lifted approximately three inches before halting due to internal binding of the shaft. While freeing the system, slack built up in the rigging. As the load settled and shifted, the slack released, causing the pump head to drop, pinching an employee s left hand between two flange surfaces. The employee sustained partial amputations to the middle and ring fingers." | |
| 2025 | TX | Construction | "A crew was priming a cement pump. To help grout start moving through the pump, they ran a few gallons of water through it and started it in forward until the grout reached the end of the first 20-foot hose section. They then placed the pump in neutral, connected the next 20-foot hose with hose clamps, and began pumping again. As the grout traveled through the second hose, it clogged. The pump was put in neutral just as the hose kicked, and the motion traveled down the length of the hose. An employee was holding the end of the hose when it kicked up and struck him in the left side of the face, causing fractures." |

Frequently asked questions
Seek immediate medical attention and ensure the incident is documented by your employer as a workplace injury. You should also preserve any evidence of the pump's condition and any safety guards that may have been missing or malfunctioning at the time. An attorney can help you navigate the Workers' Compensation process to ensure your medical and recovery costs are covered.
Employers are required to provide safe equipment and enforce strict lockout-tagout procedures to prevent accidental activation during maintenance. If your employer failed to maintain the pump or did not provide adequate training on how to safely clear obstructions, they may be held liable for your injuries. An attorney can help you investigate whether your employer violated OSHA safety standards in your specific case.
Workers' Compensation typically covers medical expenses, rehabilitation costs, and a portion of lost wages while you are unable to work. In cases involving permanent impairment or amputation, you may be entitled to additional disability benefits. An attorney can help you review your claim to ensure you are receiving the full range of benefits you are entitled to under the law.
Many pump injuries are preventable through the proper use of machine guarding, effective lockout-tagout protocols, and regular equipment inspections. OSHA regulations require employers to ensure that moving parts are guarded and that energy sources are isolated before any maintenance or cleaning begins. If these protections were absent, an attorney can help you hold your employer accountable for failing to maintain a safe work environment.
