Which way is off for this gas tap?

[munrobasher]

Isolating a central heating boiler but the gas is already off. If you were a betting person, is this tap off or on? It rotates 90 degrees.

Off

They are off when the tap is at right angles to the pipe as yours is. When on, they are parallel to the pipe.
