Where's the fire?

Nobody ever takes pictures of these fire hydrant signs, so I thought I would. For those that are interested, the figure at the top is the size of the mains water pipe that feeds the hydrant in millimetres- in this case 75 mm. The lower figure is the distance from the plaque to where the hydrant is in metres. Please don't shoot me down in flames if I'm wrong :-) The things you learn in Blipfoto!
