Humber Refinery workers walk out for a third day in safety row
Workers have walked out of an oil refinery in North Lincolnshire for a third day.
Some 450 contract employees have stopped working at the Humber Refinery in South Killingholme claiming concerns over "safety issues".
The industrial action follows a gas leak last week in which two people were taken to hospital.
The plant's owners, Phillips 66, said it had offered to hold talks with staff and the contract firms.
GMB union officer Shaune Clarkson said his members wanted "reassurance" from management that the plant was safe.
A spokeswoman for Phillips 66 said: "This morning, despite the repeated offers by the refinery management to meet face to face with each company and their staff, the contractors voted to stay off work for a third day in unofficial action."
The company said the refinery was "not being impacted by this action".
