Abstract:
A method for remotely accessing packages suspect of containing hazardous devices, the method comprising the steps of:supplying a low pressure hydro-solution from a supply reservoir to an intensifier for pressurization to a high pressure hydro-solution; supplying the high pressure hydro-solution from the intensifier via a high pressure hose to a cutting nozzle supported by a hazardous duty robot independently moveable relative to said intensifier; aspirating said high pressure hydro-solution from said intensifier with abrasive particles from an abrasive source which feeds abrasive to said cutting nozzle independent of said high pressure hose, to form a high pressure abrasive solution; directing said high pressure abrasive solution through an appropriately sized orifice of said cutting nozzle so as to form a high velocity continuous stream flow field; and focusing said high velocity continuous stream flow field at a controlled speed and impact area below impact initiation threshold towards a suspect hazardous device.
