There has been an incident in SA involving injuries to an employee that occurred as a result of a failure of an EWP.
A knuckle on an 18M GMJ EWP may have collapsed while the employee was aloft. The employee suffered a broken leg and internal injuries.
The EWP was at working height (9m) when the top knuckle pin dislodged, the bucket fell back to its rest position (about 2.5m) with the worker and tools in the bucket. This bucket is 8 years old and had not undergone major rebuilds.
The pin retaining device appears to have failed. The fulcrum on GMJ EWPS are covered by a shroud and cannot be seen during start up inspections.
SA Safe Work is investigating and all similar EWPs have been removed from service.
All similar EWPs should be removed from service until such times as members can be assured of their safe operation.
Specifically, and in addition to all other prestart checks, members are to physically check fulcrum pins and pin retaining devices on all similar EWPs prior to any use.
