Here's some sign jumble at the local hospital. This is coded the entry/exit for ambulance crew to directly access the Accident and Emergency Department.
So the "Ambulance Staff Only" sign is properly obscured by the emergency exit sign. It might just raise the question if it's the emergency exit for Ambulance staff only....And with Red signage, that seriously instructive colour of red traffic lights.
An then there's the ordering of the signs. So first it's emergency exit, and then it's Ambulance staff only....and signs or instructions then to follow on logically from the previous ones....so emergency exit but exclusively for ambulance staff.
In reality the emergency exit sign will do it's job in all probability.....Can't help but wonder if that lack of clarity in managing the messaging - especially important ones like emergency exit - inspires enough confidence when it comes to actually managing an emergency.....
