The widows of two stonemasons who died from a lung condition contracted during their work have warned of the dangers of the "new asbestos".
Paul Gray and Stuart Johnson, who worked for the same stone production companies in Bradford and Leeds, were diagnosed with silicosis caused by silica dust.
Law firm Irwin Mitchell, which secured settlements for their families after their deaths in 2019 and 2021, has claimed that West Yorkshire is a "hotspot" for exposure to the dangerous mineral.
After an increase in reported cases of the disease, Irwin Mitchell has launched a national register for stoneworkers to record incidents of contact with the dust.
