Ten fire engines and around 70 firefighters tackled a grass fire on Warley Road in Upminster.
An area of around six acres of grassland and shrubbery was affected by the fire.
Those in the vicinity were advised to keep their windows and doors closed due to smoke being produced and avoid the area where possible.
One of the Brigade's wildfire response vehicles was deployed to the scene to provide off-road capability, enabling the transportation of additional equipment closer to fires on open ground. Each vehicle carries approximately 475 litres of water, a backpack blower, ear defenders, beaters and misting lance technology, which allows firefighters to pump water and drive, enabling them to tackle grass fires more quickly and safely. The Brigade is currently trialling four wildfire response vehicles across the capital.
The Brigade's Control Officers took the first call to the fire at 1524 and mobilised crews from Harold Hill, Hornchurch, Romford, Ilford and surrounding fire stations to the incident. Firefighters from Essex County Fire and Rescue Service were also on scene. The fire was under control by 1653.
The cause of the fire is under investigation.
