Which step for transferring propane does not belong?

• A. Determine the amount of propane to transfer
• B. Prepare the evacuation site
• C. Connect the piping to the outlet of the regulator
• D. Evacuate liquid propane

Answer: (C)

Transferring propane safely hinges on using the correct connection points and preparing the area to prevent hazards. The step that does not belong is connecting the piping to the outlet of the regulator. Regulators are designed to reduce gas pressure for use in appliances, not to serve as a transfer connection point. Hooking piping to the regulator outlet could bypass proper transfer connections and safety controls, increasing the risk of leaks, unintended discharge, or overpressure. The other steps fit with safe transfer practice: determining how much propane to transfer helps prevent overfill or waste; preparing the evacuation site ensures the area is clear and ventilated and free of ignition sources; and evacuating liquid propane from the area reduces the chance of liquid spills or pooling, which can be dangerous.
