Spontaneous Combustion
Spontaneous combustion often occurs in piles of hydrocarbon-soaked (oily) rags and can constitute a serious fire hazard. Fires started by spontaneous combustion are caused by the following mechanisms: (i) spontaneous heating, (ii) pyrophoricity, and (iii) hypergolic reactions. Spontaneous heating is the slow oxidation of an element or compound ...
