Provided is a blast-free alternative tool for breaching operations for the intended purpose of cutting metal, including rebar, steel cables, I-beams, thin walled containers, welding doors, and the like. The apparatus includes a flexible and cuttable tube containing metal oxide/metal (thermite) mixture, capable of being formed around a target material and of NONEL ignition. The apparatus can be used to cut, weld, or ignite target material. Protective caps are included with provisions to insert shock tube or time fuse to transmit ignition to first fire mix. A fire proof or flame retardant flexible outerwrap with adhesive (such as hydrogel) or malleable retention wires covers the cutting ribbon for heat and slag retention. In the preferred embodiment, the apparatus is issued/manufactured in rolls or precut lengths.

The present disclosure relates to a detonation connector having an exposure part for tagging, the detonation connector includes: an electrically conductive wire-connecting bracket member having a plurality of electric wire mounting grooves to which a leg line or a leading line is mounted; a lower casing member at which the wire-connecting bracket member is positioned; and an upper casing member covering the lower casing member, wherein the upper casing member or the lower casing member is provided with a tagging exposure part that exposes a part of the wire-connecting bracket member wire-connecting the leg line and the leading line, so that the tagging work of charging initialization time to a detonator can be performed without opening the upper casing member, and the convenience and the efficiency of the tagging work can be improved.

A fast utility access device (FUAD) is provided that includes one or more casings, each of the one or more casings collectively defining a bore, and a core of a highly exothermic composition contained in the bore and surrounded by a thermally insulating inner liner, the highly exothermic composition ignitable to create a post-ignition temperature of between 500° C. and 4000° C. A method is also provided for breaching a target and includes contacting the inventive access device with a breaching target substrate, thermally coupling at least one reaction initiator to the highly exothermic composition, triggering the at least one reaction initiator thereby igniting the highly exothermic composition, and allowing the highly exothermic composition to achieve a post-ignition temperature sufficient to melt the breaching target substrate, forming a hole therethrough.

Provided is a multi-configuration transportable demolition pouch that includes a cruciform shaped section of fabric with a central explosive containing area and four trimmable flaps, a fastener on each of the flaps, a strap accepting slit, a first and a second strap, a fabric lid and priming hole, and one or more energetic device that can be selected based on desired blast footprint. The pouch can be trimmed when using smaller quantities of explosives to reduce its footprint and facilitate ease of carrying and emplacement. The device has attachment features to aid in transport and to provide proper spacing and attachment points for demolitions and breeching techniques involving multiple charges. The pouch provides components to allow for blast footprint alteration and for water tamping to reduce blast effects to nearby personnel, as well as to increase the efficiency of the explosive charge.
