  • Do not use a rupture disc in a location where the sudden release of the material would pose a hazard.
  • The burst pressure is marked on the top of the disc retainer. Do not subsitute any other burst disc. A DeTec disc must be used.
  • Make certain there is an isolation valve between the system being sampled and the rupture disc assembly. This is necessary so the system can be closed if the disc bursts.
  • Expansion of liquified gases due to small temperature changes may cause a rupture disc to release the cylinder contents. Appropriate regulations and guidelines should be followed to establish safe filling limits.
