The bulletin says that angled fishplates welded to each external corner of the hollow jib section had failed and that a metallurgical examination indicated fishplate welding was associated with the failure.
WorkSafe has ordered all Italmec work platforms in Australia to undergo radiographic testing of their boom and jib welds and that any identified as unsafe to be immediately removed from service until the testing has been completed.
Thankfully structural failures such as this are very rare, and while it is hard to say after such a tragic incident if a harness and short lanyard had been used, a life would most likely have been spared. A second man in the platform suffered minor injuries.
It is also a little dissapointing that this bulletin has taken over eight months to be issued. It was clear on day one that a structural failure was likely to have been the cause and metalurgical tests do not take months to perform.
