I think you need specific training to touch this stuff, that means registration and that the fire brigade need know who you are.....
It needs MPB inside the house
It needs a separate Earth Electrode
It needs an earthing point, usually a brass stud for the tanker to make an electrical connection to disperse static.
It does not need a PME export (you must decide what is the best route here)
This liquid gas is lethal, if it leaks it lays on the floor, its flash point percentage changes unlike natural gas and when it goes, it chases you around like Australian green crabs.
So beware and have the appropriate insurance. You have been warned !
