It's thought engineers ignited redundant oil waste
Fire crews have been tackling a blaze within a redundant gas storage tank in Plymouth.
Four fire engines as well as an aerial platform ladder and water carrier were sent to the scene just before 12:40pm on Thursday 4 May.
The cause of the fire has since been deemed accidental. It's thought engineers on site were dismantling the gas storage tank and accidentally ignited redundant oil waste.
The fire covered an area of 10 square metres at its peak.
