Give me an example of CBox Packaging has general duties under the Health and Safety at Work etcAct…

4. When might CBox still be liable if a subcontractor causes harm?
CBox remains liable when it retains control over the work, sets unsafe procedures, fails to check contractor competence, or does not supervise and monitor activities. Liability also arises if CBox’s premises, equipment, or processes created the risk. Responsibility persists despite subcontracting the task.
