Abstract
A heat-responsive fuse cord is positioned in the proximity of a pressure vessel and is thermally coupled to a thermal-pressure relief device which is in communication with the pressurized contents of the vessel. When ignited the fuse cord burns to a thermal coupler, transferring the heat to the thermal actuator of the TPRD. In a kit form, fuse cord and a thermal coupler provide an economical remote and retrofit triggering system for TPRD's having an otherwise limited environment of influence.
