Which action is not recommended before filling a propane container?

The action that is not recommended before filling a propane container is allowing multiple people inside the RV. Maintaining a safe environment during the filling process is crucial, as propane is highly flammable and can create dangerous situations if proper precautions are not taken.

Having multiple people inside an RV can lead to distractions and increase the risk of accidents during the filling process. Propane filling should ideally be performed with a minimal number of people present, allowing the focus to remain on safety measures and proper procedures.

In contrast, inspecting the container is vital to ensure that it is in good condition and free from leaks; monitoring the pressure helps prevent overfilling; and ensuring all appliances are turned off reduces the risk of ignition sources during the filling operation. These practices contribute to a safer environment, which is essential when handling propane.
