* Elmac’s Policy on Stable Detonation Arresters

Elmac Technologies has a clear policy on stable detonation arresters.

In summary it concludes:

  • Unstable detonations are much more destructive events than stable detonations
  • The location of unstable detonations cannot be predicted with any certainty
  • A stable detonation may undergo sudden transition to an unstable detonation
  • It follows that use of a stable detonation arrester in isolation is not sufficient to protect a system from transmission of a flame and exposes the user to significant risk.
  • In any system where detonation events are a possibility, an appropriately designed and tested unstable detonation arrester device should be fitted.
