Video narration
A man takes a shortcut behind a parked dumper. Then the driver climbs into the cab and starts reversing. The worker is right beside the machine—but the driver has not confirmed he is there. From the cab, “right next to it” does not mean visible. The cab height, mirrors, bodywork, and size of the dumper can hide a person completely. That hidden area is a blind spot: ground the driver cannot see from the seat. And it is not just one small patch. Depending on the machine and conditions, areas around it can remain invisible, even while someone is close enough to be struck. So before you approach mobile plant, stop where the driver can see you. Get eye contact. Follow your mine's approach and traffic rules; eye contact does not replace them. The driver cannot act on what he cannot see. Never assume you've been seen.
