Abstract
A system for safely transporting detonating cord that uses a container with a mounting board of insulating material with a walled path through which the cord is threaded. The path has a series of loop regions and adjoining, parallel regions through which the parallel cord is separated with a cord separator that will sever adjoining cord in the event of a detonation to terminate further cord detonation. A separator card of cardboard is an ideal separator means. The walled path must otherwise insulate the detonating cord, being formed in one embodiment of cylindrical cardboard tube and in another of expanded polystyrene having a path with an open top. Fastener means secures the detonating cord within the walled path, being 'Nylon' in the tube embodiment and interference fit in the expanded polystyrene embodiment.
