Pull off 10 individual needles from your fresh sprig. The material itself produces heat sufficient to reach its own ignition temperature. The white space at the bottom of the diamond has a W with a slash through it to indicate water reactivity. The main factors causing SC fires are: biological activity; relatively dry compost piles; larger and more well-insulated piles (compost and composting feedstocks are good insulators and are more insulating as they dry out); limited air flow and reduced free air space; poor moisture distribution (the critical moisture content that supports SC is 25%-40%); a nonuniform mix of materials; and poor or incomplete temperature monitoring. If hot enough, the gases may become ionized to produce plasma. Even after the cessation of microbial activities, the core temperature of a compost pile will continue to climb above 160F (70C) if there is low moisture content in the compost pile.

But if the pile temperature gets too high probably 180 Fahrenheit or higher, and is exacerbated by elevated environmental temperatures, there is a risk of spontaneous combustion. Peanuts, or rather their oil, can create quite a bang if used to make dynamite. The rags used to apply linseed oil were placed in a plastic container in a storage room in the hangar, just below the living quarters.

Spontaneous combustion can take place when a substance having a relatively low ignition temperature (straw, peat, hay, and more) begins to release heat. More importantly, piles with large chip particles, usually allow the methane to ventilate to the atmosphere. Even without oxygen, the pile will continue to burn or char due to chemical reactions.
