At what pressure do outlets need to be either D.I.S.S. or designed to relieve pressure before removal of the adapter?

The requirement for outlets to either be D.I.S.S. (Diameter Indexed Safety System) or designed to relieve pressure before the removal of the adapter is established to ensure safe handling and prevent accidents during gas transfer operations.

In this context, the critical pressure threshold is 80 psi. This level of pressure is significant because it minimizes the risk of gas expulsion, which can be hazardous. At pressures above this threshold, the potential for sudden release of gas increases, making it imperative that outlets meet safety standards designed for such operations.

D.I.S.S. fittings are specifically engineered to prevent incorrect gas connections and to safely manage pressures associated with compressed gases. When a system is designed to relieve pressure, it ensures that any residual gas is vented safely before disconnection, further enhancing safety for users.

Choosing a pressure level of 80 psi ensures a balance between operational functionality and user safety, making sure that system integrity is maintained and the risk of injury is reduced during the process of equipment disconnection.
