Abstract:
1. A safety system for use in transporting a first fluid between a fluid source and a container comprising: an elongated flexible cylindrically shaped hose having a central opening capable of transporting a first fluid therethrough, said flexible hose having a first end and a second end; a first valve located at said first end of said hose and a second valve located at said second end of said hose; each of said valves being moveable between a closed position and an open position so as to control the flow of said first fluid through said hose; said central opening of said hose being surrounded by a conduit wall integrally formed therewith, said conduit wall extending substantially the entire length of said hose; a plurality of enclosed channels within said conduit wall and extending substantially the entire length of said hose, each of said channels being in the form of a spiral; said plurality of enclosed channels each containing a second fluid under pressure; valve operating means operatively associated with said second fluid within said channels and sensing the pressure thereof, said operating means closing both of said valves when said sensed pressure falls below a predetermined level.
