Prohibition Sign - Recycled Water In Use Do Not Drink

Correct! AS 1319 (the Australian Standard for Safety Signs) specifies that Prohibition Signs are designed to communicate actions or activities that are not allowed in a certain area. These signs must follow specific visual requirements:

1. White Background: The base of the sign should be white for clear visibility.
2. Red Annulus and Slash: A red circular border (annulus) with a diagonal slash across the prohibited action symbol (typically black or dark color) in the center of the sign, indicating that the action shown is not allowed.

These signs help maintain safety by preventing unsafe actions and guiding appropriate behavior in various settings.
