Abstract
A safety pressure relief device of the reverse buckling type includes a puncturing element and a rupture disc having a groove or score line formed in the flange portion of the disc. The score line does not materially affect the rated pressure of the device during normal operation, and functions as a backup safety feature by providing a line of weakness along which the disc will tear if the pressure relief device is accidentally placed in a backward or reversed orientation with respect to the process, and/or if the cutting blades are inadvertently omitted from the rupture disc assembly.
