Where should the open end of piping systems being purged not discharge?

The open end of piping systems being purged should not discharge into confined spaces or areas with ignition sources to prevent the accumulation of flammable gases or vapors. When purging gas lines, it is critical that the discharged gases are released into an area that allows for proper ventilation and dispersion. Confined spaces can trap gases, potentially leading to hazardous conditions, such as explosions or toxic exposure. Areas with ignition sources increase the risk of igniting any flammable gases released during the purging process. Therefore, ensuring safe discharge locations is essential for maintaining safety standards and mitigating risks in accordance with the National Fuel Gas Code.
