SECTION 460:25-13-11. Use of detonating cord  


Latest version.
  • (a)   Care shall be taken to select a detonating cord consistent with the type and physical condition of the bore hole and stemming and the type of explosives used.
    (b)   Detonating cord shall be handled and used with the same respect and care given other explosives.
    (c)   The line of detonating cord extending out of a bore hole or from a charge shall be cut from the supply spool before loading the remainder of the bore hole or placing additional charges.
    (d)   Detonating cord shall be handled and used with care to avoid damaging or severing the cord during and after loading and hooking-up.
    (e)   Detonating cord connections shall be competent and positive in accordance with approved and recommended methods. Knot-type or other cord-to-cord connections shall be made only with detonating cord in which the explosive cord is dry.
    (f)   All detonating cord trunk lines and branch lines shall be as near to 90 degree angles as possible and free of loops, sharp kinks, or angles that direct the cord back toward the oncoming line of detonation.
    (g)   All detonating cord connections shall be inspected before firing the blast.
    (h)   When detonating cord milli-second-delay connectors or short-interval-delay electric blasting caps are used with detonating cord, the practice shall conform strictly to the manufacturer's recommendations.
    (i)   When connecting a blasting cap or an electric blasting cap to detonating cord, the cap shall be taped or otherwise attached securely along the side or the end of the detonating cord, with the end of the cap containing the explosive charge pointed in the direction in which the detonation is to proceed.
    (j)   Detonators for firing the trunkline shall not be brought to the loading area nor attached to the detonating cord until everything else is in readiness for the blast.
