<P> Hay must be fully dried when baled and kept dry in storage . If hay is baled while too moist or becomes wet while in storage , there is a significant risk of spontaneous combustion . Hay stored outside must be stacked in such a way that moisture contact is minimal . Some stacks are arranged in such a manner that the hay itself `` sheds '' water when it falls . Other methods of stacking use the first layers or bales of hay as a cover to protect the rest . To completely keep out moisture , outside haystacks can also be covered by tarps , and many round bales are partially wrapped in plastic as part of the baling process . Hay is also stored under a roof when resources permit . It is frequently placed inside sheds , or stacked inside of a barn . On the other hand , care must also be taken that hay is never exposed to any possible source of heat or flame , as dry hay and the dust it produces are highly flammable . </P>
