ABSTRACT:
A system for transferring a product from a source which includes a safety cut-off feature for preventing the transfer of the product. The system includes a tubular member adapted to handle the transfer of the product therethrough, a remote connector, a product connector, and an electric circuit. The tubular member has a proximal end, a distal end, and at least two separate conductive paths, including first and second conductive paths, each extending between the proximal and distal ends. The remote connector is attached to the distal end of the tubular member for conductively connecting the first and second conductive paths in series. The product connector supplies the tubular member with the product from the source and conductively connects to the second conductive path, whereby the product connector and the tubular member define a product transfer path. The electric circuit passes an electric current through a monitored electrical path which includes the first conductive path, the remote connector, the second conductive path, and the product connector, and terminates the transfer of the product in response to an interruption in the electric current. Preferably, at least one of the components may be releasably attached for easy reattachment after separation.
