Just been visiting a site that uses red lamps to indicate that a machine is on and green lamps to indicate that a machine is off.. the logic being that if it is on the red lamp indicates there is a potential danger.
Seems a bit daft to me as, going by the logic of traffic lights, green should be go (run) and red stop.
Just wondered what the balance of opinion was and if, anywhere in the world, there was any kind of standard for this...
Sad question, I know, but its Friday afternoon and so I'm just winding down for the weekend.
