Description
Protect worker hearing and enforce PPE compliance with this AS 1319 high-noise warning sign. The yellow-and-black triangle format signals a caution-level hazard, prompting staff to don ear protection before entering the zone. Choose from corflute, Colorbond steel, or polypropylene in three sizes: 300×225 mm for tight spaces, 450×300 mm for standard workshops, and 600×450 mm for large factory floors. Lamination and reflective upgrades boost longevity in noisy, dusty environments. Bulk orders to trade accounts include volume discounts and Australia-wide delivery.
Final sign type, wording, size, placement and material depend on the site risk, project specification and applicable jurisdiction. Confirm the requirement with the relevant WHS adviser or regulator.

Frequently asked
Should I use corflute or steel in a wet factory environment?
Colorbond steel resists moisture and chemical splash; corflute suits dry or covered areas. Polypropylene offers a middle ground for damp (but not wet) workshops.
How far away can workers read a 450×300 mm sign?
Typically 3–5 metres in good light. For larger open floors or outdoor zones, the 600×450 mm size ensures legibility from 8–10 metres.
Does lamination really extend the sign's life?
Yes. Lamination protects against scratches, UV fading, and minor impacts, extending lifespan by 50–100% in high-traffic or outdoor settings.
Can I order signs for multiple noise zones at once?
Absolutely. Order different sizes in a single transaction—use 300×225 mm in confined machine areas, 450×300 mm in main workshops, and 600×450 mm in large open floors. Bulk pricing applies to the total order.
What's the fastest way to get signs on-site?
