An explosive whose action is practically instantaneous.
A gun fired by a percussion cap.
A device containing a small detonating charge that is used for detonating an explosive, including, but not limited to, blasting caps, exploders, electric detonators, and delay electric blasting caps.
Something that will set off or initiate an explosive.
Electrical blasting cap. Unstable compounds such as high explosives require initial shock or other disturbance to set off the chemical reaction. A blasting cap is usually used to set off Primacord, which in turn sets off shaped charges.
A percussion cap which can be clipped to the rail and detonated by the wheels of a locomotive passing over it. This provides an audible warning, particularly useful in foggy conditions where semaphore signals are employed.
a mechanical or electrical explosive device or a small amount of explosive; can be used to initiate the reaction of a disrupting explosive
a contrivance containing a very sensitive explosive, used to fire a larger charge of a less sensitive and more manageable explosive
a device such as a fuse or percussion cap that's used to set off an explosive charge
a device used to trigger bomb s, shaped charge s and other forms of explosive material and explosive device s
a little disc-shaped explosive device that, when a train ran over it, would explode with a loud noise
Put into the gelignite stick (explosive) and set alight.
A device containing an initiating or primary explosive that is used for detonation.
A disc shaped small explosive with pliable metal clips which are placed on the top surface of the rails to warn drivers that a signal obscured by fog is at danger or that there is an obstruction ahead.
A railway detonator (also called a torpedo in the U.S.) is a device used to make a loud sound as a warning signal to train drivers. The detonator is the size of a large coin with two lead straps, one on each side. The detonator is placed on the top of the rail and the straps are used to secure it so that it does not fall off.
