This emergency stop button appears to indicate that the red button must be rotated clockwise to operate it to the OFF position. Should it not be marked PUSH, so that anyone knows what to do to operate it in an emergency?

When in Rome etc.
The examples below show just what good wording can indicate. They just lack one thing. The indication to PUSH the button not rotate it, as may be directed by the stupid arrows.

Note the language used Andy.

These RED stop signs are better than the green one. They are obvious in their instruction and result if used. PRESS TO STOP is the clear message.

RED is good, it aligns with RED at traffic lights=STOP.
Just like motor starter switches RED = STOP. (And GREEN = START or GO).

Well, even the French have the word, "STOP" on their road signs.

No, see reply a few minutes earlier regards BS EN 60073.
Red means "DANGER" or "FAULT".
Green means "SAFE" or "NORMAL"
It also aligns with BS 7671 colour for protective conductor- was green, but now green-and-yellow (because internationally no-one could agree on solid green) - being the protective conductor, or "safety conductor".
Germany used to go with "red" = "safety conductor" (protective conductor), but I'm led to believe that the red there meant to indicate "do not mess with this" ... I'm not so sure about that last little anecdote.
This is all very inconsistent. An emergency stop mushroom switch actuator is coloured RED. Red for "danger. I think not. It is RED for STOP. Green can not mean SAFE if a machine is switched on. Traffic light colours are internationally known.
