4.15. INITIATOR AND DETONATOR SAFETY
4.15.1. INTRODUCTION Initiator safety is the removal of an initiator(s) from an explosive chain. The majority of IEDs are initiated by a detonator. If the detonator is separated from the main charge or booster then the IED cannot function as intended. This is referred to as ‘detonator safety’. Conducting detonator safety correctly is an important process of an IEDD task and is a requirement before a device can be classed as rendered safe. It should be done at the earliest appropriate point in the RSP. 4.15.2.WHY IS CONDUCTING DETONATOR SAFETY ‘GOOD PRACTICE’? Detonators are filled with a primary explosive which is extremely sensitive to initiation / detonation by impact, friction, electrostatic discharge, or the application of flame. As such, they are a reliable means to start the detonation process in an explosive chain. Until the detonator is removed the IED’s main charge remains in an unsafe state, even after component separation of any electrical circuit, mechanical mechanism, or igniferous fuze. Care must be taken when handling any detonator given that they are likely to be more sensitive to shock and impact than the explosives in the main charge. Extra caution again must be exercised when handling damaged military / commercial detonators, or improvised detonators. In a damaged military / commercial detonator, the primary explosive may be crushed inside the casing, or exposed to the elements. In such a condition, it is inherently more sensitive than normal, and the application of pressure, friction or heat could cause it to function. Similarly, the components of an improvised detonator have not been produced to the same standards of manufacturing as commercial and military detonators. They are therefore unpredictable in terms of their sensitivity and can be extremely responsive to external influences.
ׁ WARNING. Unless improvised detonators can be transported in a container which can resist a detonation, it is advised that they are disposed of at the task site.
