Two Gold Coast workers died on 22 June 2008 when they fell 26 stories after a suspended scaffold collapsed.
According to WorkCover, scaffolding collapses can be prevented if operators undertook adequate risk assessments and control measures.
Riggers or suspended scaffold operators should ensure the scaffold is erected by appropriately licensed and competent personnel. The structure should also be inspected after installation to ensure it is safe for use.
Additionally, scaffolding counterweights should be at least three times the maximum likely load in the support rope, and the suspension rig should be capable of supporting the scaffold and provide adequate lateral stability.
Counterweights should be fixed to the suspension rig to prevent dislodge, and the scaffold hoist should contain a single rope protective device or a second rope to hold the scaffold if the winch malfunctions.
