Beschreibung
Zusammenfassung:	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.
