Investigations are continuing into the cause of a fire which broke out in a former aircraft hanger on Tuesday night.
Six fire engines were called to tackle the blaze involving a large amount of plastic at Silloth airfield.
Investigations into the cause are continuing but Cumbria Fire and Rescue Service say it's not suspicious.
Phil Stannet, from Cumbria Fire & Rescue Service, said: "We're continuing with works at the moment to dig out the remaining tonnage that's left behind.
"It's going to take us another couple of days actually to get through all this material, to dig it through and damp it down.
"But also a lot of the water run-off that we need to contain to prevent it going into the water courses so we're in discussions with the Environment Agency to contain that water and get it taken away."
