Last week a coroner's jury sitting in Northampton returned a verdict of accidental death after hearing how Kenneth Raisborough, a 48-year-old father of three, died while helping lay a path for the council at Daventry Country Park.
He crashed the dumper truck he was driving into a stationary JCB digger and was crushed by its bucket. He had not been trained to drive the vehicle.
HSE inspector Paul Thomas told the inquest: 'I believe none of the dumper truck operators had any previous experience.' The HSE is considering whether to prosecute the council over the accident, a spokesman said later.
