A Member has reported an incident in which a crewman was struck and injured by an out-of-control rotating handle.
What happened?
The incident occurred on a small vessel during the deployment of a stand-alone echosounder. This required the use of an over the side pole to deploy the echo sounder. The crewman was lowering the echosounder pole by means of a small winch when the handle slipped from his grasp and started to rotate quickly. As he tried to grab the handle to regain control over the winch, the edge of the handle struck his forearm causing a deep cut which subsequently required seven stitches.
Pole and winch
Pole and winch
Our Member’s investigation noted the following:
- The requirement for an over the side pole arose due to a necessary change of vessel, only one week before mobilisation.
- There was no detailed specification in place for the required pole and winch mechanism.
- Responsibilities for the design, manufacture, installation and acceptance of the pole and winch were not clearly allocated.
- The installed winch was not suitable as it had no safety mechanism to prevent free fall when lowering.
- This hazard was not identified, as existing robust risk management procedures were not followed.
Our Member drew the following lessons:
- Clear responsibilities should be defined to ensure all tasks are controlled and executed in a safe manner.
- Formal specifications for equipment should be provided to ensure that the installed equipment meets that specification. Failure to do this means there is no baseline to permit a user to determine if change management is required.
- Failure to comply with existing robust procedures can allow hazards to go undocumented.
- Handovers at shift and crew changes should be thorough, formally documented and cover all potential issues. Failure to do this can result in essential information and knowledge not being passed on.
Our Member took the following corrective actions:
- Standard specifications were developed and distributed for this form of over the side pole and winch mechanism.
- Written instructions to be provided to project managers and field crew covering:
- Requirement for completion of task risk assessment and any associated method statements before project mobilisation
- Need for clear understanding and documentation of responsibilities associated with projects
- Involvement in pre-project meetings, hazard id and risk assessment (HIRA) and kick-off meetings
- Requirement for formal documented project briefing for operational personnel
- Requirement for better formal documentation of project communications
- Requirement for adherence to management of change process
- Requirement for formal documented handovers when personnel changed out
- Requirement to stop the job in the event of an unsafe condition.
