Ten fire engines and around 70 firefighters were called to a fire at an old coal depot in Tavistock Road in West Drayton on Sunday afternoon (28 April).
A container, an industrial conveyor belt, 15 vans and three articulated lorries were alight.
Station Manager Jon Holt, who was at the scene, said: "The fire was very visible and produced a lot of smoke. Crews worked hard to bring the fire under control as quickly as possible and to stop it from spreading."
At the height of the fire residents and businesses were advised to keep doors and windows closed as a precaution. Train lines were also temporarily closed for the safety of rail passengers while firefighters tackled the blaze.
The Brigade’s 999 control officers took more than 55 calls to the fire. Around 15 people left the depot site before the arrival of the Brigade. There were no reports of any injuries.
The Brigade was called at 1416 and the fire was under control by 1815. Fire crews from Hillingdon, Heathrow, Feltham and other surrounding fire stations attended the scene.
The cause of the fire is under investigation.
