Mandatory Sign - Hearing Protection Must Be Worn In This Area

Correct! Under AS 1319 standards, Prohibition Signs are indeed used to clearly indicate that a specific action or activity is prohibited. The design requirements specify that these signs must have:

• A white background for visibility,
• A red annulus (circular border) with a slash symbol that typically cuts diagonally across a black pictogram representing the prohibited action.

This combination ensures that the sign is easily recognizable and effectively communicates restrictions for safety purposes.
