Brigade top tips on grass fires:
- Don't have barbecues in parks, public spaces or on balconies.
- 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- don’t drop cigarettes on dry ground and don’t drop them out of car windows, as they may land on dry grass and lead to a fire.
- Disposable barbecues that have been discarded and abandoned can still end up causing a fire as they will continue to retain heat after use – they need to be put right out and cooled before being thrown
