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?

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.

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.
