Prohibition Sign - No E-Cigarettes

That’s correct! Under AS 1319-1994, Prohibition Signs are indeed used to indicate actions that are not allowed. The design standard requires these signs to have:

• A white background for visibility,
• A red annulus (ring) and slash that crosses through a black symbol depicting the prohibited action.

This red slash makes it immediately clear that the activity shown is not permitted, ensuring high visibility and comprehension for safety compliance. These signs are commonly used in workplaces to prevent unauthorized activities and enhance safety by visually communicating restrictions.
