To what percentage is a propane container typically filled?

A propane container is typically filled to 80% of its capacity to allow for the expansion of gas when temperatures rise. Propane, like other gases, expands and contracts with temperature changes. By filling the container to this level, it ensures there is enough space for the gas to expand without the risk of overpressure, which can lead to safety hazards such as leaks or explosions. This practice is a standard safety measure in the propane industry and is reflected in regulations governing the safe transport and use of propane.

Other filling percentages would increase the risk of pressure issues; for example, filling above this threshold could lead to overflow or dangerous pressure increases with temperature fluctuations. Therefore, maintaining an 80% fill level is critical for both safety and functionality.
