There must be Heat (ignition temperature) to start and continue the combustion process. Spontaneous ignition occurs when this double or triple bond breaks and creates heat and the heat is confined. WD-40 does not spontaneously combust. It is always a good idea to meet with your local fire department and agree on procedures for handling a SC fire, particularly if it is observed after hours and they get called first. Compost piles can self-ignite when the heat generated during decomposition is trapped inside a dry, insulated, and compacted pile with small particle size and pockets that are low in oxygen. 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. The spontaneous combustion process begins very slowly and the heat of the reaction increases until combustion occurs. Remember that rained-on hay may have toxins associated with spoilage.
