Safe disposal of ash from your stove

Safe disposal of ash from your stoveHETAS is advising homeowners to safely dispose of ash from their wood burning and multi fuel stoves following a recent carbon monoxide incident and a house fire.

Hot and cooling ashes can be a fire and carbon monoxide hazard. Make sure that you leave sufficient time after a fire to let the ash cool and keep the door to the stove closed. Ensure that all disposing of ash is done so with the correct equipment, such as safety gloves. Use a galvanised steel or metal ash can or bucket that can be sealed to collect all the unwanted ash. Take your time to remove the ashes to avoid any ash spreading across your room. Slowly transport the container outside of your house and dispose of in a designated area. Do not allow ash to collect in the bucket inside your house for any period of time.

Some stoves operate with a small amount of ash, check your appliance user instructions for best practice for your stove.

Coal ash should always be disposed of safely, wood ash can be used in several ways once cooled. Check with your local council for specific guidance for disposal of ash into general waste.
