450x300mm Mandatory Sign | High-Noise Zones

The Double Hearing Protection Must Be Worn sign is a mandatory sign used to alert personnel that standard earplugs or muffs alone are insufficient for the noise levels present. It belongs in high-decibel environments such as mining sites, heavy fabrication workshops, and airport tarmacs where acoustic hazards are constant and severe.

Installing these safety signs at the entry point of a high-noise zone ensures that every worker is aware of the requirement before they enter the danger area. By clearly stating the need for double protection, typically a combination of earplugs and over-ear muffs, the sign helps prevent long-term hearing loss and noise-induced trauma. Site supervisors and safety officers can use these to maintain a strict safety protocol, ensuring that contractors and employees don't overlook the necessary gear when moving between different zones of a construction site or plant.

This specific sign is manufactured from metal and measures 450x300mm. It is produced in accordance with AS1319-1994 to ensure the messaging is clear and recognised across the site.
