And let's not forget that your refrigerator is usually pretty far from the pump. Like 30' away kind of away. It's going to take an awful lot of fumes to fill the area enough to get ignitable gas fumes 3' off the ground 30' away from the pump.
However, it's not technically impossible, so if you hop out of your rig and the place reeks of gas, I wouldn't want to stick around.
If you are going to shut it off, remember that you need to shut the fridge off, not just the propane. Even with the propane off the DSI will still try to spark as long as the fridge is turned on and you haven't gone to a lockout state. The spark is what you need to watch out for (again only if the gas fumes can reach ignitable concentrations).
