What must be done when abandoning a container underground?

When abandoning a container underground, it is essential to remove as much remaining gas vapor as possible through a vapor connection. This practice is crucial for safety reasons. Propane is highly flammable, and any remaining gas vapor poses a significant risk of explosion or fire if it accumulates within an enclosed space. By ensuring that the gas vapor is adequately removed, you can mitigate these risks effectively.

The process of vapor removal also aligns with proper environmental standards and regulations, as it helps prevent potential leakage of propane into the surrounding soil and groundwater. This action demonstrates responsible handling of hazardous materials, which is an important aspect of propane safety protocols.

Filling the container with sand or sealing it completely may not adequately address the potential hazards associated with residual gas, and simply leaving the container as is could lead to serious safety issues. Therefore, removing the gas vapor is the most effective and recommended procedure when abandoning a container underground.
