It seems spontaneous combustion was behind a barn fire in Waterford in recent days.
Fire crews from Waterford City Fire Service attended a blaze on Tuesday.
In a post on their social media, they say moisture is usually considered a way of putting out a fire but under certain conditions it can actually cause one.
When hay and straw are baled at moisture levels over 20%, mesophilic bacteria release heat that can lead to spontaneous combustion.
This particular fire was quickly brought under control before any severe structural damage could be caused.
