A large compost pile can spontaneously combust if improperly managed. 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.

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. [50] Hay stored outside must be stacked in such a way that moisture contact is minimal.
The autoignition temperature or self-ignition temperature, often called spontaneous ignition temperature or minimum ignition temperature (or shortly ignition temperature) and formerly also known as kindling point, of a substance is the lowest temperature at which it spontaneously ignites in a normal atmosphere without an external source of ignition, such as a flame or spark.

Spontaneous combustion of grass or manure piles causes numerous fires each year. Moisture in wet hay piles fosters microorganism growth, which generates heat as they decompose the organic material.
Sep. 25—Moisture and hay are sworn enemies. Not only will wet hay grow mold that can be unhealthy for farm animals, but the microbial activity can generate so much heat that the bales will light ...
Miehe was the first person to work with thermophilic microorganisms in his study of the spontaneous combustion of damp haystacks. T. lanuginosis was one of four species of thermophilic fungi isolated from self-heating hay by Miehe, along with Mucor pusillus, Thermoidium sulfureum, and Thermoascus aurantiacus. [2]
A non-combustible material [17] is a substance that does not ignite, burn, support combustion, or release flammable vapors when subject to fire or heat, in the form in which it is used and under conditions anticipated. Any solid substance complying with either of two sets of passing criteria listed in Section 8 of ASTM E 136 when the substance ...
Airplane food often gets a bad rap. As it turns out, it's not entirely the airlines' fault that food tastes different at 30,000 feet than it does on terra firma — and it's not all in your head ...
