DO THE SMELLS OF DETONATORS, FUSES, BOOSTERS, benefit us?

0  comments

A not entirely uninteresting thought is that various explosives require an initial detonator. In some form, this must be in contact with the explosive to ignite it – be it by means of a fuse, power cord, etc. In order to do this, we must first take a closer look at the multiple possibilities of ignition in order to be able to make a judgment at all. Let us start our analysis by listing the ignition possibilities as precisely and comprehensively as possible. Detonating cords and ignition amplifiers (boosters), shock tubes and ignition pills, electric detonators, and their timing, EMatches and squibs, use of taggers, ignition devices and ignition keys, blasting accessories such as ignition machines, ignition machine testers, ignition switches, ignition current distributors, ignition circuit testers, ignition wire, extension wire, end-circuit measuring devices, stray current measuring device, ignition connectors. Let us start now with the things that we may already encounter on the way to the detection site / operation site and therefore we must also include them in our training:

➢ Detonating cord

➢ ignition booster

➢ Detonator

➢ Electric detonators

➢ Non-electric detonators

➢ Electronic detonators

➢ E-matches and squibs

Detonating cord

A detonating cord consists in the inner core, the so-called core, and consists of powdered PETN, but also of hexogen and octogen. This is mechanically wrapped with foil and covered with threads of plastic and cotton threads. We already have PETN on page 69/70 in our list of substances to be trained and we can therefore also condition the substance via the detonating cord (if it is made of it – read manufacturer’s note), but we have a few cross-smells from the manufacture with it (plastic, cotton etc.).

Ignition booster (so-called booster/primer)

Ignition boosters are made of highly explosive materials. For example, either TNT, PETN, RDX and their mixtures. They must therefore also be trained.

Detonator

A blasting cap is a closed metal shell. It has a primary charge and a secondary charge. The primary charge usually consists of lead azide as the initial explosive. The secondary charge usually consists of explosive, but mostly nitropenta. The detonator can only be made by means of a fuse (powder rim fuse). This always consists of black powder. At the latest now we know why black powder is to be trained and leads us to the actually dangerous detonator. Nitropenta and black powder are to be trained for this.
