An investigation is being carried out at the aluminium smelter in Fort William after a visiting lorry driver was injured in an accident involving a 16 tonne forklift truck.
The Health and Safety Executive (HSE) is also involved and confirmed that it was “making initial inquiries”.
The man, who has not been named, was taken to the Lochaber town’s Belford Hospital by ambulance suffering from pelvic injuries following the incident on the Rio Tinto Alcan site.
It is understood that he was later transferred to Raigmore Hospital in Inverness, but no information was available regarding his condition.
A reliable source said the man had been crushed between the lorry he was driving and the forklift while aluminium ingots were being loaded onto his vehicle.
A spokesman for the company confirmed that there had been an incident involving a visiting lorry driver and a 16 tonne forklift truck belonging to Rio Tinto Alcan, but he would not confirm that the man had been crushed.
He said: “There was certainly contact between the person and the forklift and I believe he has a broken pelvis.
“We are conducting an internal investigation into the incident and informed HSE, although we did not have to do that as he is not employed by us.
“It is unfortunate that this happened but, on the other hand, it is quite fortunate as I think it could have been worse.”
He added that they had been loading 12 tonne ingots that were to be transported to the Midlands when the accident happened at around 2pm on Tuesday July 29.
A spokeswoman for HSE said it was aware of the incident and was making initial inquiries.
