Where must all purging be directed if boundary conditions #1 or #2 are met?

Purging should always be directed outdoors when boundary conditions #1 or #2 are met to ensure safety. This practice is critical to prevent the accumulation of hazardous gas concentrations within enclosed areas, which could lead to potential explosions or toxic exposure. By directing purging outdoors, any residual gas that is purged from the system can dissipate into the atmosphere where it poses minimal risk to individuals and the surrounding environment. This precautionary measure is an essential part of gas handling procedures, particularly in maintaining safe operational practices during the commissioning or servicing of gas piping systems.
