Contributory factors vary between incidents, but include:

• no planning to develop a safe system of work that considers
  • exclusion zones
  • designated lifting areas
  • control or elimination of simultaneous activities within the lifting area
• failure of lifting equipment
• lack of information, training, instruction
• inadequate supervision.

When lifting, lowering or suspending loads, PCBUs and other duty holders must ensure that:

• they have consulted with workers, including contractors to identify hazards and manage risks associated with this task
• workers are given information, training and instruction on the hazards, risks and control measures
• workers have the correct licence for the work, if necessary
• work is planned, and designated lifting areas, landing areas, paths of travel and exclusions zones are identified
• when determining the size of exclusion zones, all risks arising in relation to the work are considered
• the plant, any attachments and lifting components (such as chain slings, synthetic slings and hooks) are suitable for the load
• all plant and lifting components are rated to lift the load
• lifting components are protected from sharp corners of the load
• the plant and lifting method selected is suitable for the load and the load remains stable throughout the activity, never causing loads to swing
• the weight and centre of gravity of the load is known
• the working environment is considered, including temperature, heat sources (e.g. weld spatter), chemical use (corrosive environments), power lines and other obstructions
• loads are never moved or suspended over a person
• all lifting components are visually inspected before each use, and tested according to the manufacturer’s instructions and in-line with any relevant Australian Standard recommendations
• damaged or worn equipment is never used
• work is appropriately supervised to ensure that safe systems of work are followed
• a safe work method statement or lifting plan is prepared
• lifting components are stored in a clean and dry location  
• lifting slings are never dropped, thrown down or dragged
• personal protective equipment is provided and workers are trained in its use and maintenance.
