Four fire engines and around 25 firefighters tackled a grass fire on South End Road in Rainham.
A 75 metre by 75 metre area of shrubland was destroyed by fire.
All firefighters have received enhanced training for grass fires and wildfires. The welfare of operational crews working in hot weather conditions is a key priority and firefighters are provided with additional hydration packs, sun cream and protective headwear for personal protection on the incident ground.
London Fire Brigade is also trialling new wildfire response vehicles this summer, which have off-road capabilities and technology that allows firefighters to pump water while driving, enabling them to tackle an outdoor fire more quickly and safely.
Today's fire comes as London experiences high temperatures with a yellow Heat Health alert issued by the UK Health Security Agency. During this type of weather, the risk of grass fires increases and the Brigade is asking the public to follow crucial safety advice that will help protect themselves, others, the environment and their property.
London Fire Brigade Assistant Commissioner for Prevention and Protection, Craig Carter, said: "We know many Londoners will want to enjoy the nice weather by visiting a park or open space. However, we’re asking people not to take disposable barbecues with them as they can cause grass fires, especially in hot weather when the ground is dry. These fires are unpredictable and can spread rapidly, causing a significant amount of damage.
"Don’t be tempted to barbecue on your balcony either. Balconies can contain combustible materials which can pose a risk to those barbecuing and others living nearby.
"If you are having a barbecue, never leave it unattended and be careful where it’s positioned. Aim for level ground and keep barbecues well away from anything flammable like sheds, fences, trees or tents."
As well as disposable barbecues, discarded smoking materials and leftover rubbish also pose a huge fire risk. People are asked to ensure their rubbish is placed securely inside a bin or to take it home with them. If you have had a cigarette, please make sure that it is completely out.
The Brigade was called at 1456 and the fire was under control by 1554. Crews from Dagenham, Hornchurch and Stoke Newington fire stations attended the scene.
