FIXOR™ INITIATION METHODS

ELECTRIC OR NON-ELECTRIC DETONATOR

  • FIXOR™ Binary Explosive can be detonated by an electric or non-electric detonator.

  • Detonators tested to date have contained 0.8 grams of PETN. If only lower strength detonators are available, then test the reliability of FIXOR™ detonation before any deployment against ordnance. If a FIXOR™ fails to detonate, the bottle will rupture and a localized FIXOR™ fire will result. An alternative is to use detonating cord as detailed below.

  • The detonator should be positioned so that there is a distance of 75 mm (3 in.) from the end of the detonator to the top of the FIXOR™. Mark this distance on the detonator leg wires prior to insertion of the detonator into the FIXOR™ to ensure proper detonator placement.

  • Simultaneously initiate multiple FIXOR™s by using detonating cord as detailed below. Tests have shown that there may be a slight delay between the firing times of the detonators and this will disrupt the FIXOR™s causing them to fail to detonate (as evidenced by the FIXOR™ burning).

  • Do not bundle FIXOR™s together and then initiate only one of the FIXOR™s in the bundle. Propagation of the detonation between the FIXOR™s is not reliable.
  • Bottles of FIXOR™ must be individually initiated as propogation of the detonation wave is not reliable.

    DETONATING CORD AND SIMULTANEOUS DETONATION OF MULTIPLE FIXOR™S

  • FIXOR™ can be detonated by "sensitized detonating cord", which is detonating cord with a military or commercial detonator crimped on the end of the detonating cord. Initiate the detonating cord using normal firing procedures.

  • FIXOR™ can be detonated by detonating cord with a ULI knot (similar to a hangman's knot) tied in the end of the detonating cord. The ULI knot should have at least 6 turns in it. Initiate the detonating cord using normal firing procedures.

  • The detonator or ULI knot in the detonating cord should be positioned so that there is a distance of 75 mm (3 in.) from the bottom end of the detonator or ULI knot to the top of the FIXOR™. Mark this distance on the detonating cord prior to insertion of the detonating cord into the FIXOR™ to ensure proper detonator or ULI knot placement.

  • When simultaneously initiating multiple FIXOR™s use a short length of "sensitized" or ULI knotted detonating cord in each FIXOR™. Bring the other ends of the detonating cord together and initiate all of the lengths of detonating cord with one detonator. This will ensure that all of the FIXOR™s will detonate simultaneously.
