ABSTRACT:
A barrier assembly for a safety and arming electro-explosive device of the type comprising a rotor containing detonators and rotatable between safe and arm positions includes a body of lead as an energy absorbing material in the safe position of the device. When the shock wave from a detonator hits the lead, the lead flows and attenuates the shock wave. Cycling after the device has been fired in the safe position is precluded by an undercut in the rotor into which the lead flows, thus preventing rotor rotation after firing.
