The family of a man who died from an aggressive asbestos-related cancer are urging his former colleagues to come forward.
Kenneth Sanderson, from Worksop, died aged 78 in January 2010 from mesothelioma.
His relatives believe old workmates may hold vital clues to help in their battle for justice.
It is believed he was exposed to asbestos while working at G R Stein Refractories Limited - later known as Hepworth Refractories Limited - in Worksop, where he worked as a kiln car operator between 1973 and 1991.
His two sons, Richard and David, have instructed industrial illness experts at Irwin Mitchell to investigate working conditions at the company.
Richard said: “Before he died he was convinced he was exposed to asbestos while working at G R Stein Refractories, a company he worked at for almost 20 years. We just want to find out whether he was exposed to asbestos while working there and if anybody thinks they can help we urge them to come forward.”
Helen Ashton of the industrial illness team at Irwin Mitchell, said: “Mesothelioma is an aggressive form of cancer which has devastating affects for victims like Mr Sanderson and their families.
“Because it can take up to 30 or 40 years to develop it can be difficult to assess where somebody was exposed to asbestos.
“We urge anyone who worked there or believes they may know more information to come forward and help with our investigation.”
