Around 120 LFB firefighters and officers have been fighting a warehouse blaze on Wadsworth Road, Perivale.
Around 30 people left the building before the Brigade arrived and there are no reports of any injuries.
All of the roof and the first floor have been fully alight with the billowing clouds of smoke seen for miles.
The warehouse is made up of mixed factory units.
Station Manager Jeff Lisle who is at the scene said:
Crews are working very hard is difficult conditions. Firefighters are using aerial ladder platforms to tackle the fire from numerous vantage points and ensure the blaze doesn’t spread to neighbouring warehouses. While we are making excellent progress, we expect to work on this fire into the night.
This isn’t a residential area but the smoke is travelling quite a distance so do keep windows and doors shut if you are local.
20 fire engines are at the scene including engines from Heston, Northolt, Chiswick, Wembley, Park Royal, Ruislip, Ealing, Hammersmith, Willesden and North Kensington fire stations.
