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?

Doesn't comply with the current standard, as the direction of rotation to reset is not provided.
I suspect it doesn't latch off, so doesn't need to be reset - rather like the ones we had in the metal workshop at school when I were a lad - you just had to find a separate green button to turn things on again.

" that, under the old BS 5499-5, which was withdrawn in 2011, the sign had a red background. Under BS EN ISO 7010 that replaces it, the sign has a green background, aligning with the concept of 'green indicates the safe way or safety/emergency procedure' like emergency exits, first aid signs, assembly points and RVPs, etc,"
So on a motor starter it often has a green button for on and a red button for off. Green for GO or green for safe? A conflicting situation.

that follows the principles of BS EN 60073, for "operating, no fault". Safety signs also align with this standard.

Safety signs usually are taught with H&S courses in the workplace - I guess we could also say that self-employed persons have the same duties to inform themselves in the way an employer informs their employees about safety signs.
But I don't see a lot of awareness in the industry - outside those who deal directly with industrial controls and machinery - about BS EN 60073.
