Before beginning the autogas refueling process, which of the following actions should be taken?

• A. All of the above.
• B. Make sure the vehicle is turned off.
• C. Touch a grounded object to control static electricity.
• D. Do not smoke, strike matches, or light a cigarette lighter.

Answer: (A)

All of these steps are important before refueling autogas. Turning the vehicle off removes the engine and other potential ignition sources from the fueling area. Discharging static by touching a grounded metal part helps prevent a static spark from igniting LPG vapors. And avoiding smoking or any open flames ensures there isn’t a fuel ignition source near the filling point. Taken together, these precautions reduce the main ignition risks involved with LPG fueling, so doing all of them is the best practice.
