Blast bomb Blast bomb is a term used in Northern Ireland for a type of improvised explosive device. More specifically, these devices are usually a form of homemade grenade, which is thrown at a target. These devices have been used in a number of public order situations, and in attacks on the Royal Ulster Constabulary, its successor Police Service of Northern Ireland (PSNI) and British Army. A police officer was killed by a blast bomb in Northern Ireland during The Troubles by loyalists and in 2001 Loyalist protesters threw a blast bomb at Catholic schoolgirls, some as young as 4 years old, making their way to school in September 2001. Ordinary fireworks are sometimes used in a similar fashion to blast bombs. Such devices which are packed with nails are referred to as nail bombs.
Explosive train A triggering sequence, also called an explosive train, is a sequence of events that culminates in the detonation of explosives. 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'.
