Fire services and park authorities have been urging people to avoid using sky lanterns during the clap for key workers.
Derbyshire Fire and Rescue said: "They pose a risk to wildlife, moorland, hazardous material sites and more" stating that it puts added pressures on fire services and the NHS.
They are encouraging people to 'clap for cares' and draw rainbows, but not to let off lanterns.
Their calls are joined by The Peak District National Park who encouraged people to use alternative methods to show support.
There are lots of ways to show your support of our amazing key workers and NHS heroes, but releasing sky lanterns is not one of them. Clap loud and clap long this week, and send those sounds soaring into the sky instead.
Meanwhile, the Marine Conservation Society put out a reminder, that "what goes up must come down" accompanied by two images showing the impact sky lanterns have on wildlife.
The plea has been backed by University Hospitals of Derby and Burton NHS who said they "can't wait to hear your clapping this evening" but urged people to think of the risks lanterns can pose.
