A triggering sequence, also called an explosive train or a firing train, is a sequence of events that culminates in the detonation of explosives.[1] For safety reasons, most widely used high explosives are difficult to detonate. A primary explosive of higher sensitivity is used to trigger a uniform and predictable detonation of the main body of the explosive. Although the primary explosive itself is generally a more sensitive and expensive compound, it is only used in small quantities and in relatively safely packaged forms. By design there are low explosives and high explosives made such that the low explosives are highly sensitive (i.e. their Figure of Insensitivity is low) and high explosives are comparatively insensitive. This not only affords inherent safety to the usage of explosives during handling and transport, but also necessitates an explosive triggering sequence or explosive train. The explosive triggering sequence or the explosive train essentially consists of an 'initiator', an 'intermediary' and the 'high explosive'.
For example, a match will not cause plastic explosive to explode, but it will light a fuse coupled with a blasting cap which will detonate a primary explosive that will shock a secondary high explosive and cause it to detonate. In this way, even very insensitive explosives may be used; the primary detonates a "booster" charge that then detonates the main charge. Triggering sequences are used in the mining industry for the detonation of ANFO and other cheap, bulk, and insensitive explosives that cannot be fired by only a blasting cap or similar item.
