What happened?
A worker broke his finger while removing the screw pin on a shackle.
Three workers were loosening the screw pin on a bow shackle that was attached to an excavator. One of them used a pin bar to loosen the screw pin.
The shackle was unsteady, so a second worker came to hold it but was unable to keep pressure on shackle.
A third worker put pressure on the shackle to help steady it but lost his grip, pinching his fingers between shackle and the attach point on the excavator.
-
Why did it happen?
- Workers’ hands were in the line of fire.
- Workers held shackle to steady.
- Workers rushing and did not take time to reassess hazards.
-
What did they learn?
- Screw pins should only be tightened to the shoulder of the pin.
- Workers were encouraged to take the time to refine hazard identification, including hand placement.
- Use of stickers to indicate pinch points and use of high-impact gloves.
- Potential for hand injuries discussed during safety and tailgate meetings.
- Employer sent out company wide communication reminding workers and supervisors to take time before each task to identify potential hazards.

Ask yourself or your crew
- How can something like this happen here (e.g. on our site)?
- What safety measures (i.e. procedures, controls/barriers) do we have in place to mitigate the risk?
- How do we know the risk controls/barriers are working?
- What improvements or changes should we make to the procedures, controls/barriers or the way we work?
