Cross wiring multiple explosive devices vs. single load explosive device

Detonator-trigger

There are four different types of detonators you can use in order to activate your primary explosive (blasting cap):

1. Mechanical detonator

2. Electrical detonator

3. Chemical detonator

4. Fuse detonator

I would suggest choosing one of the following detonation devices:

Fuse (EASY)

Buy visco fuse or similar high quality fuse. Choose the most reliable fuse type (6mm in diameter is usually more reliable than 2,5 mm fuses but is harder to come by). Cover the fuse in surgical tubing or the sparks from the fuse may cause early detonation (from either nitro/fuel /chem fumes, or sparks may come into contact with load). There are several different types of fuses. Burn rate is usually 1cm per second (this should be specified on the supplier site) so if you want 2 minutes for evacuation you will need 1,2 meter fuse etc. Web addresses to European suppliers are found at pyroforums. If you’re going to use a fuse, you must normally add a little (1g-3g black powder or similar in the receiving end of the primary charge in order to successfully initiate the rest. You should create a blasting cap and arrange a test prior to operation.

Wireless Radio Firing Systems (MODERATE)

Sold by companies specializing in fireworks detonation systems. Consists of two parts: 1 x Receiver with battery source and 1 x Remote control with battery.

Like the 1Q version from: http://www.e-madeinchn.com/FiringSystems.html

There are other European, US and Chinese companies selling similar items. The 1Q version sold on that site costs 16 USD + 5 USD shipping. This specific version is a 6V with relatively short range: 200 m. You basically just place the receiver close to the charge and plug wires into the chromatic wires, similar to the one you find in light bulbs.

Mobile phone (MODERATE TO HARD)

Same principle as above, just that you use the battery power from the receiver mobile. When you call the receiver mobile with your transmitter mobile (providing you have sorted the wiring from your receiver mobile into the detonation cap (chromatic wires)

Never try to cross wire multiple explosive devices unless it is an absolute requirement. Instead; always focus on single load explosive devices. To illustrate this we can review the 2010 Stockholm Jihadi suicide bombers fatal mistake. By cross wiring 5 pipe bombs he had increased the chance for failure by several hundred percent. With a single load explosive device the chance for failure is approximately 20%. As you attempt to cross wire 5 of these devices you are increasing the chance for failure to 80-95%. Needless to say; this is an unacceptable risk.

a Assessment of affordability based on costs of material from chemical supply houses (except for active halogen-type biocides, as indicated by footnote c).

b As determined by the committee based on its experience and information provided by Richard Strobel, ATF, in a personal communication, September 11, 1997.

c Available from garden, swimming pool, and racing supply outlets.

d Precursor requiring chemical reaction for conversion to an explosive.

e Typically available as aqueous solution.

f Ca(NO3)2/NaNO3/NH4Cl/Calcium cyanamide.

g Includes nitromethane.

The above overview obviously does not consider the approach of using “alternative” easily accessible bulk explosives loads such as LNG platforms, LNG tankers, propane trucks etc. In these cases, you would only be required to create a booster charge of 50-100 kg as the bulk of the explosives would be the civilian vessel itself.
