Firefighters have dealt with a series of moorland fires over the last two weeks, with the continued heatwave leaving the ground tinder dry.
A number of crews from Derbyshire have been helping colleagues from Greater Manchester Fire and Rescue Service with a huge blaze on Saddleworth Moor, which has been burning since last Monday.
And Peak District firefighters have also been tackling a fire in the Staffordshire Moorlands, which has been burning since Saturday.
Derbyshire Fire and Rescue Service is asking people to take extra care as the heatwave continues.
Area Manager, Bob Curry said, “We’re asking members of the public to be vigilant and to help us by taking steps to minimise the number of grass fires we are attending.
“The ground and vegetation is tinder dry and anything that can cause a spark can soon escalate to a fire on a large scale.
“Discarded cigarettes, outdoor barbeques and discarded glass bottles can all pose a serious threat when conditions are so dry.
“I’d also like to appeal to people to delay having any garden fires at the present time, as they too have the potential to spread rapidly, as tinder dry grass and overhanging trees can soon cause the fire to spread to fences, sheds and even homes.”
