Yes, according to AS 1319, Prohibition Signs are indeed used to indicate that certain actions or activities are not allowed. They have a distinctive design with:

• A white background for clarity,
• A red annulus (circle) with a diagonal red slash, usually covering a black pictogram that represents the prohibited action.

This design is standardized to ensure clear and consistent communication of restricted actions across different environments, aiding safety and compliance in workplaces and public spaces.
