A sprinkler system prevented a serious fire at an industrial recycling warehouse in Kensal Green on Thursday (March 16) night, firefighters have said.
Around 15 workers evacuated the building in Scrubs Lane before London Fire Brigade (LFB) attended, after being called 11.02pm.
An industrial shredder containing construction waste was completely gutted in the blaze, according to the LFB.
The fire was under control by 2.06am.
Park Royal watch manager Dan Green, who was at the scene, said a sprinkler saved further damaged.
He added: "The sprinkler system undoubtedly helped contain the fire from spreading further.
"Firefighters also worked extremely hard to create a water relay from a nearby canal which meant we were able to limit damage and bring this under control quicker."
A spokesman for LFB used the fire as an example for other businesses to follow.
The spokesman said: "As well as being potentially life saving devices, sprinklers help with business continuity by minimising disruption and allowing businesses to get back to normal as soon as possible."
Fire crews from Park Royal, Acton, Wembley, North Kensington, Paddington, West Hampstead, Northolt and Fulham attended.
