Coroner's Finding: Wicks, Benjamin

Contributing factors

• failure to conduct proper risk assessment when work method changed on the day of work
• inadequate documentation and formal consideration of the new sling-based method
• use of non-compliant lifting equipment (sling not subject to required inspection program)
• pre-existing damage to the sling
• failure to bench or level the embankment area despite it being proposed and feasible
• inadequate depth and integrity of pre-augered holes on the slope
• lack of coordination between principal contractor Hutchinson and subcontractors
• failure to involve Calcraft management in method planning
• toolbox meeting did not cover the changed method adopted later that morning
• workers positioned within exclusion zone below suspended load
• pile becoming airborne and twisting during maneuvering over embankment
• sling failure under load

Coroner's recommendations

1. Adopt safe work method practices that include documented safe work method statements outlining the piling method, risk assessment, hazard identification, and control measures
2. Include assessment of any lifting gear including slings in safe work method statements
3. Maintain a register to record the owner of any lifting gear used on work sites during piling operations
4. Implement requirement that work stops and is reviewed with documentation if there is a change to work method involving new piling methods or use of lifting gear such as slings
5. Consult with all employees about piling operations on site
6. Ensure coordination between principal contractor and other contractors retained for specific work such as piling
7. Implement effective site management to account for and review changes in work methods
8. Implement effective hazard identification and risk management procedures
9. Ensure detailed safe work method statements set out the work method and allow for documented review and modification with work stopped until completion
10. Ensure all lifting gear used or brought onto site is compliant with relevant standards and fit for purpose with maintenance records reviewed prior to use
11. Ensure exclusion zone controls are understood by workers and appropriate supervision is undertaken to enforce such zones
12. Ensure principal contractors effectively liaise with all contractors on site to address safety concerns particularly regarding piling operations involving loose ground, changing ground conditions, or difficulties with pre-augering and standing of piles prior to driving
