Mandatory Sign - High Noise Area Hearing Protection Must Be Worn

That's correct! AS 1319 outlines standards for safety signs in Australia, and it specifies the design and use of Mandatory Signs to communicate essential instructions that must be followed. The key characteristics of these signs are:

• Symbol and Color: Mandatory Signs feature a white symbol on a blue circular background, which makes them easily recognizable.
• Message: The signs typically include the word "MUST" in the message to emphasize the requirement.
• Purpose: They are used to ensure compliance with safety protocols and procedures, indicating actions that need to be performed to maintain safety and health standards in various environments.
