The commercial and military version of a burning fuse referred to as safety fuse (invented by William Bickford) is a textile tube filled with combustible material and wrapped to prevent external exposure of the burning core. Safety fuses are used to initiate the detonation of explosives through the use of a blasting cap.
The primary hazard of pyrotechnic blasting caps is that for proper usage, the fuse must be inserted and then crimped into place by crushing the base of the cap around the fuse. If the tool used to crimp the cap is used too close to the explosives, the primary explosive compound can detonate during crimping. A common hazardous practice is ...
At the end of each cylinder, Nobel inserted a blasting cap which could be ignited in one of two ways. First, by inserting a safety fuse into the blasting cap and igniting the fuse. Second, by attaching an electrical wire onto the blasting cap and producing a current which would travel from the source to the blasting cap. [11]
Detonating cord (also called detonation cord, detacord, detcord, blasting rope, or primer cord) is a thin, flexible plastic tube usually filled with pentaerythritol tetranitrate (PETN, pentrite). With the PETN exploding at a rate of approximately 6,400 m/s (21,000 ft/s), any common length of detonation cord appears to explode instantaneously.
The exploding-bridgewire detonator (EBW, also known as exploding wire detonator) is a type of detonator used to initiate the detonation reaction in explosive materials, similar to a blasting cap because it is fired using an electric current. EBWs use a different physical mechanism than blasting caps, using more electricity delivered much more ...
Because standard safety fuse burns at around half a metre per minute, it is not practicable to provide delays of more than a few minutes in this way. It was also possible to connect a pencil detonator to so-called "instantaneous fuse" (not to be confused with detonating cord) which had an unusually fast burn rate of over 7 metres per second.
Electrical cable (or fuse) connected to the blasting cap. Dynamite is an explosive made of nitroglycerin , sorbents (such as powdered shells or clay), and stabilizers . [ 1 ] It was invented by the Swedish chemist and engineer Alfred Nobel in Geesthacht , Northern Germany, and was patented in 1867.
