A fire which scorched an area of grass the size of a football pitch in Feltham has sparked another warning to smokers.
The blaze, which spread rapidly, damaged a large area of the greenery, behind a school on Dudley Road, on Wednesday (July 22) afternoon.
The London Fire Brigade (LFB) were called at 12.39pm and the fire was under control by 1.44pm, a spokesman confirmed.
Earlier this month, another grass fire damaged a swathe of heathland in Hounslow.
An LFB spokesman said: "Grass fires can be started deliberately or accidentally, but however they start they can cause huge damage to property and kill wildlife.
"A small spark from a cigarette is often all it takes to start a grass fire.
"It really is important that smokers dispose of their cigarettes properly.
"Drivers also need to take care not to throw cigarettes out of car windows as they can easily burn grass verges.
"If you see a grass fire, don't attempt to put it out yourself as they can be fast moving and change direction without warning.
"Call the fire brigade and let us know where the fire is.”
The cause of the fire is under investigation.
