Significant Incident Updates

1. Significant Incident Updates Cape Lambert Port B (14.11.12) Crush Injury From Slewing Crane – Lost Day Injury Although there were extensive injuries the worker is expected to make a full recovery in time A worker accessing a rigging box was caught between the crane counterweight and the rigging box whilst accessing shackles as the crane slewed. The employee was treated onsite by site paramedics and transferred to Nickol Bay hospital before being airlifted to Royal Perth Hospital for further assessment and treatment.

2. Significant Incident Updates Cape Lambert Port B (14.11.12) Crush Injury From Slewing Crane – Lost Day Injury • The incident highlights an opportunity for learning and improvement in the identification of hazards and also the selection of all appropriate controls required during tasks involving people and moving machinery. • Preliminary findings: • Communications: The agreed method of communication “hand signals” was unable to be sustained when the rigger moved out of sight of the crane operator. • Task assignment: The rigger and the crane operator did not have the same understanding about task sequencing. Assumptions were made by both parties about when and how the rigging equipment would be collected from the rigging box without confirmation. • Agreed point of control: The crane operator and the rigger had both assumed they were in control of the task without confirming with the other party. • Risk Management / Change Management: Whilst an equipment risk assessment was in place for the crane, this did not take into account the new hazards introduced when access to the upper deck (rigging box) was restricted and access from the ground was mandated. • Area Access Controls: Controls put in place to prevent access to the slew area of the crane focused on the area of the hook and did not address the area impacted by the slewing counter weight.

3. Significant Incident Updates Cape Lambert Port B (14.11.12) Crush Injury From Slewing Crane – Lost Day Injury • Preliminary Recommendations: • Communications: Implement an agreed and tested form of communication (radios) for all tasks that involve person/s leaving the line of sight. • Task assignment: Ensure clear and defined roles for each person involved in the task (i.e. Repeat back of instructions when performing high risk tasks) ensure specific task steps are agreed and documented in the JHA / Lift plan before conducting works. • Agreed point of control: Task assignment should include a clear allocation of each involved persons accountabilities – including defining the person in charge of the task (there can only be one at any given point in time). • Risk Management / Change Management: Review the conditional and behavioural risk assessments for mobile equipment to ensure appropriate controls are in place which will prevent access to pinch areas around moving parts and attachments. • Area Access Controls: Physical barriers (exclusion zones) should be considered and implemented to prevent people accessing hazardous areas away from the line of sight of the crane operator. Consideration should also be given to engineering solutions such as, limit switches – radio frequency devices (proximity switches) and movement alarms. The Incident Investigation is due for completion on the 3/12/2012. All actions and lessons learned will be distributed via the final HSE Alert
