It is very difficult to establish a unified theory of what occurs in hay self-heating because of the variation in the types of grass used in hay preparation, and the different locations where it is grown. The process may begin with microbiological activity (bacteria or mold), but at some point the process has to become chemical. It is anticipated that dangerous heating will occur in hay that contains more than 25% moisture.

Note: The tendency to self-heat decreases with the increasing rank of the coal. These metrics are regularly updated to reflect usage leading up to the last few days. In the presence of excess moisture that is just below the level required for germinating seed, the activity of mold fungi is a likely candidate for generating heat. In lieu of an abstract, this is the article's first page. Spontaneous combustion or spontaneous ignition is a type of combustion which occurs by self-heating (increase in temperature due to exothermic internal reactions), followed by thermal runaway (self heating which rapidly accelerates to high temperatures) and finally, autoignition.[1].
