Six fire engines and around 40 firefighters were called to a grass fire in Perivale Park in Greenford.
Approximately three hectares of grass and shrubland were destroyed by fire.
Firefighters used backpack blowers, which work just like leaf blowers, to tackle the fire. They allow firefighters to push flames back into already burnt areas. This is a tactic that provides a faster, more efficient attack on wildfires. Wildfire beaters were also used. The beater is made of a long handle with a flat piece of rubber at the end. They’re used to beat the flames, which deprives them of oxygen and cools them down.
A London Fire Brigade spokesperson said: "Once again we have a heatwave in London. Throughout this period of hot weather, we are continually monitoring demand and deploying our resources where they are needed most so that we're ready to respond to emergencies across London.
"While we are fully prepared to respond, we need everyone to play their part in helping to prevent incidents. Wildfires in particular can spread rapidly, require significant resources and have devastating consequences for people, properties, wildlife and the environment. Wildfires can also have a lasting impact on the health of Londoners because of the smoke plumes that they produce.
"If you're heading to a park or open space to enjoy the sunshine, please don't take a disposable barbecue with you. Even after they have been extinguished, they can retain heat for many hours and pose a serious fire risk. Please also dispose of smoking materials responsibly and either use the bins provided or take your litter home if there are none available.
"If you're having a barbecue at home, never use one on a balcony. Position it well away from fences, sheds and other combustible materials, and avoid placing it on wooden decking."
