When filling a receiving container with propane, it is essential for it to be purged beforehand. Purging eliminates any air or moisture present in the container, which is crucial for ensuring safe and efficient filling. Air and moisture can lead to issues such as pressure fluctuations, contamination of the propane, and potentially dangerous situations like explosions or combustion. Proper purging helps create a controlled environment that allows the propane to fill the container effectively without any impurities.

Additionally, while it might seem beneficial for the container to be completely empty before filling, purging focuses on removing unwanted gases or liquids that could compromise the integrity of the propane. Therefore, ensuring the container is purged is fundamental in maintaining safety standards during propane transfer processes.
