What action is taken to prevent propane containers from becoming dislodged?

The appropriate action to prevent propane containers from becoming dislodged is to install them to withstand eight times their filled weight. This approach enhances the structural integrity of the installation, ensuring that the containers can endure significant forces, such as those caused by wind, seismic activity, or transport-related vibrations. By designing the installation to withstand such extreme conditions, the risk of dislodgement due to external pressures is minimized, thus providing a safer environment for storing and handling propane.

While other methods may contribute to securing propane containers, they do not provide the same level of assurance as ensuring that the installation can handle a weight factor significantly greater than the actual filled weight. Using chains or reinforced structures can help in securing the containers, but without the robust safety margin of eight times the filled weight, they may not fully prevent dislodgement in extreme conditions.
