What is a critical safety consideration when using LPG containers?

Ensuring LPG containers are not overfilled is paramount for safety. Overfilling can lead to the release of liquefied gas, which can escape as vapor and create a hazardous situation. It raises the risk of leaks, increases pressure within the container, and can result in dangerous conditions such as explosions or fires if ignited. Proper filling practices include adhering to the manufacturer's fill level guidelines, which allow for the necessary vapor space, thereby preventing pressure build-up and potential accidents. Other options focus on improper handling or conditions that would inherently increase risk rather than mitigate it.
