What is the maximum filling percentage for an LP gas container?

The maximum filling percentage for an LP gas container is 80%. This is established to allow for the expansion of the gas within the container, accounting for changes in temperature and pressure. Liquid propane expands as temperatures increase, and if the container were filled beyond this percentage, there would be a risk of overpressure and potentially dangerous situations.

Filling a container to 80% ensures there is adequate space, known as vapor space, for the gas to expand, thus maintaining the integrity of the container and safety standards. This regulation is in place to prevent any incidents related to overfilling, such as leaks or ruptures.

It's important to be aware of this standard for safety compliance in the handling and storage of LP gas, ensuring both the safety of operators and the general public.
