This is what I have come up with.
Arizona Revised Statutes say:
5-362. Diver flag
A red flag with white diagonal stripe from staffhead to opposite corner shall be recognized as a diver flag and shall be displayed when a person or persons are actually diving below the water surface and are equipped with apparatus to allow such person or persons to breathe under water.

And from the Game & Fish Department in their "Boaters Guide" it says:
It's the Law: On the Water
Diver-Down Flags
* Scuba divers and snorkelers must display a diver-down flag to mark their diving area. The flag must be displayed whenever someone is diving below the surface.
* Vessels should stay as far away from a diver-down flag as is reasonable and prudent for the circumstances. The suggested safe distance from a flag is 100 yards.
