	There are three "phases" to a chemical chain reaction, first being the '''initiation''' or the initial spark, the next being the '''propagation''', and the final state being the '''termination''' where the system reaches a stable state.<ref name=uc/>		There are three "phases" to a chemical chain reaction: first being the '''initiation''' or the initial spark, the next being the '''propagation''', and the final state being the '''termination''' where the system reaches a stable state.<ref name=uc/>

	A burning candle or other [[fire]] is an example of a chemical chain reaction. When a [[flammable]] material is surrounded by enough oxygen and is exposed to a source of heat or temperature above the flash point, a fire starts. If there is sufficient oxygen, fuel, and heat ~~while the fire is burning~~ it will continue to burn until there is no longer enough of one of these three components to maintain the chemical chain reaction of the fire.
