For proper functioning, how far should a purge line be from a building?

The recommended distance for a purge line from a building is 20 feet minimum. This requirement is primarily based on safety considerations, as it helps prevent the accumulation of gas near the structure. A purging operation involves releasing gas from a system, and being at a sufficient distance minimizes the risks associated with any gas leaks or the potential for ignition.

In addition, positioning the purge line at this distance ensures that any gas released is adequately dispersed in the ambient air, reducing the concentration of gas in proximity to windows, doors, and ventilation openings of the building. This practice aligns with safety codes and regulations designed to protect both people and property from hazards associated with flammable gases.

By adhering to this guideline, technicians enhance the safety of operations involving gas systems, ensuring compliance with the necessary regulations and minimizing the risk of potential hazards.
