'Chinese' sky lanterns
Recently 'Chinese' lanterns or sky lanterns have become popular at birthdays, weddings and other celebrations. Although we cannot state that you should not use them, they do pose risks. Some issues are:
Risks
Not biodegradable
The paper can degrade in about six to eight weeks. But the wire in them can last nine months and is of a fine gauge with sharp ends. There are some without wire that use cane, wool or string – but these still take time to degrade and could cause issues for livestock and littering.
Fire risk
There is evidence that their use has caused moorland or forest fires at certain times of year when vegetation and weather conditions have made sites vulnerable to fire.
Danger to livestock
There have been examples of cattle and sheep eating the lanterns and wire. This has caused injury to stomachs and mouths. There are recorded cases in the UK of death from internal injury.
Contaminates hay and silage
Farmers cutting grass for stock feed or bedding can gather wire and other lantern parts in the grass, which in turn is fed or used as bedding for stock.
Litter
Even though some parts are biodegradable they do remain on view either on the ground, in trees and hedges, which is an eyesore.
Can be confused with distress flares
The UK Coastguard has been called out on false alarms when lanterns have been confused with distress flares.
Disclaimers
All the suppliers have disclaimer that they have no responsibility for accidents or injury caused and that releasers of lanterns could be liable.
