The London Fire Brigade has been called to another grass fire, one of many to have occurred during the current heat wave.
The Brigade received a number of emergency calls to a large grass fire on Hounslow Heath off Frampton Road in Hounslow. Around three hectares of grassland is alight - roughly the same size as three a football pitches.
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
Four fire engines and 25 firefighters were at the scene from Feltham, Heston and Hayes fire stations.
The Brigade was called at 1350 and the fire was under control by 1557.
