In terms of safety, what is a critical factor to monitor in an LP gas system?

Monitoring the container filling percentage in an LP gas system is essential for safety because it directly impacts the risk of overfilling, which can lead to hazardous situations. The LP gas container is designed to hold gas at a certain capacity, and exceeding this percentage can result in gas expansion during temperature variations, potentially causing leaks or ruptures. Moreover, understanding the filling percentage helps in maintaining an appropriate safety margin, ensuring that there is enough space for gas expansion and preventing pressure build-up within the container.

Other factors, while they may have their own importance, do not address the immediate safety considerations related to the management of LP gas systems as directly as the filling percentage does.
