Eight fire engines and around 60 firefighters were called to a grass fire in Royal Road, West Beckton.
Approximately six hectares of grass was alight.
The Brigade's 999 control officers took 33 calls to the fire.
A London Fire Brigade spokesperson said: "During the hot weather we are attending a large number of grass fires across London.
"We’re asking the public to take care not to drop cigarettes or matches on dry grass and to keep a very close eye on barbecues.
"Dropped glass can also start fires as the sun can magnify the sun’s rays.
"Grass fires can quickly spread and cause serious damage, so if you see grass smouldering, please call 999 immediately.”
• Never leave camp fires or barbecues unattended and extinguish them properly after you have finished using them
• Clear away bottles, glasses and any broken glass to avoid them magnifying the sun and starting a fire
• Dispose of smoking materials such as cigarettes safely
• Explain to children the dangers of playing with and lighting fires
The Brigade was called at 1318 and the fire was under control at 1458, however crews are likely to remain at the scene throughout the afternoon. Fire crews from East Greenwich, Bethnal Green, Leyton, East Ham and Walthamstow fire stations attended the scene.
This incident came on the same day as crews tackled five other large grass fires across the city, with significant ones in Hornchurch, Beckenham, Walthamstow, Barnet and West Wickham.
