Electric Blasting Squibs

Low Explosives (such as Black Powder, described in Ref 1, pp B165-R to B177-R) are initiated by Fuses, Squibs and some Blasting Caps. High Explosives are initiated by Electric Blasting Caps, Detonating Cords (such as Primacord Bickford) and by Detonators... 

Electric Initiators, Activated, can be divided in 5 main classes basedon the type of transducer used for conversion of the electrical stimulus (a) resistive bridgewire, exemplified by electric blasting caps, squibs,... 

Blasting Squibs, Electric. Elec squibs are devices useful in igniting deflagrating expls(such as BkPdr), where the nature of the expl is such that it is desirable to fire the chge by means of a flame, as distinguished from dynamites and other high expls, which are initiated by the deton of expls contained in ordinary elec caps(see under Blasting Initiators)... 

Other important developments in blasting supplies have been a no-lag electric cap for seismic exploration , millisecond (MS) delay electric blasting caps , " static resistant (SR) electric caps , high temperature caps , "special oil-well detonators , "waterproof booster for exploding seismograph. sleeper charges in very deep holes , a "millisecond (MS) delay connector for delay firing of Prtmacord", " D eta prime Primers, and electric squibs for military and commercial uses (Ref 6, pp I6 87—99 also Ref 7, pp 6—7)... 

The No. 6 electric blasting cap is the one most commonly used industrially. It is similar to the electric squib, except that its ultimate object is detonation and not deflagration. In form, it is slightly longer than the squib, about I 3/8 inch, but contains a high explo-... 

No description of British devices corresponding to US electric squibs is found in Brit books on explosives in our possession, such as Refs 36, 38 51. In Ref 38, p 59 is, however, a description of an electric device which probably serves the same purpose. It is an electric powder fuse, which consists of a thick paper tube contg a small chge of Blasting Powder (Brit for Black Powder or Gunpowder), with an ordinary low-tension fusehead fixed at one end. On passing electric current thru the fusehead it flashes and sets off the BkPdr in the tube, which can... 

Electric Squibs (Also known as Electric Igniters, or Electric Actuators). These devices are intended to fire deflagrating expls, such. as a pellet or blasting Bk Pdr (Black Powder), NC (Nitrocellulose), or loose smokeless propellant. 

Attach one wire from an electric initiator blast ing cap, squib, or alarm device) to the screw or wire on... 

A squib contains an electric match plus a base charge, not unlike a detonator (blasting cap). However, a squib contains a pyrotechnic base charge, whereas a detonator contains a high explosive base charge.
