Summary
HSE warns of unintended mobile-crusher track movement following a fatal maintenance incident. Damaged control-cable insulation allowed an earth fault to trigger a track valve. The alert recommends additional cable protection and secure routing, consideration of fault monitoring, and inspection and maintenance where protection lacks monitoring, alongside appropriate isolation for maintenance.
