How should the open end of a piping system being purged discharge gases?

The correct approach for discharging gases from the open end of a piping system being purged is to direct them to an outdoor location. Purging is a critical procedure used to remove any unwanted gases or contaminants from a piping system, ensuring that the system is safe for operation and that any residual gases do not pose a hazard.

Discharging gases outdoors ensures that they are released into the open atmosphere, reducing the risk of any buildup of potentially harmful or explosive gases within an enclosed space. This practice enhances safety by dispersing the gases, allowing for effective ventilation, and minimizing the risk of ignition or asphyxiation.

Other methods, such as using a closed containment vessel or filtration system, may not be appropriate for purging gases, as they could potentially lead to pressure buildup or hinder the effective removal of gases from the system. Discharging in a downward direction only may also limit the safe dispersal of the gases and isn't a universally applicable method for all scenarios in purging operations.
