According to the U.S. Fire Administration, spontaneous fires are one of the leading causes of fires in agricultural storage facilities, such as barns, silos, and stables. This excess moisture can result in overheating of a hay stack, and combustion can result. They are used as catalysts in polymerization reactions. The primary uses are as fuel for air-breathing engines and as a propellant. Spontaneous combustion or spontaneous ignition, as it is often called, is the occurrence of fire without the application of an external heat source. It decomposes at 300F if it has not already ignited and will ignite spontaneously in air if impure. Hydrocarbon compounds usually undergo slow spontaneous combustion.

If the heat isnt enabled to dissipate it can rise high adequate to Olive oil has an auto-ignition temperature of 435 degrees Celsius (815 Fahrenheit). This presence on your pile would indicate the core temperature may be too hot for the balanced functioning of healthy soil microbes. Ill explain how several conditions can combine to cause a chain reaction leading to the spontaneous combustion of a compost pile. Self-Heating in Yard Trimmings: Conditions Leading to Spontaneous Combustion,Compost Science and Utilization, (2002), Vol. In May 2012, a house of two floors in the southwestern suburb of London in the United Kingdom was burnt down after a compost bin in the backyard self-ignited when the owners were away (Gayle, 2012, May 29). Diethyl zinc is an organo-metal compound and a dangerous fire hazard. The spontaneous combustion process begins very slowly and the heat of the reaction increases until combustion occurs. Overly dry piles contain more combustible materials. Clean-up created problems because as the phosphorus and sand mixture was shoveled into over-pack drums, the phosphorus was again exposed to air and reignited small fires.
