Abstract
A device for rendering safe a detonator firing circuit by short circuiting multiple conductors in the circuit includes a base portion and cable piercing members. The base portion has a cylindrical block and apertures for retentively receiving the cable piercing members. The cable piercing member has a first end to impinge on and penetrate a cable insulation when forcibly attached to an external surface of the cable. The cable piercing member has a low electrical resistance and impedance to generate a short circuit between conductors of the cable. Also, a method for rendering safe a detonator firing circuit of by short circuiting multiple conductor cables or a pigtail connector of a detonator system.
