A crane went up in flames at a concrete factory.
Four fire engines and 21 firefighters and officers were called to a crane that was ablaze close to Norman Road, Greenwich.
The cause of the fire is believed to be accidental and due to a hot cutting torch flame coming into contact with oil residue.
About half of the crane was damaged by fire.
Four people left the industrial site before the arrival of the fire brigade.
The brigade’s 999 control officers took more than 50 calls to the fire as smoke billowed over Greenwich and Deptford.
The brigade was called at 6.18pm on Saturday, June 30 and the fire was under control by 9.49pm.
Fire crews from Greenwich, Deptford, East Greenwich and Bexley fire stations attended the scene.
