Description
Alert workers to explosive atmospheres and materials with this AS 1319-standard yellow and black warning sign. Petrol stations, solvent stores, grain handling facilities, and pyrotechnic areas demand immediate hazard recognition. Corflute, polypropylene, Colorbond steel, and vinyl materials suit indoor storerooms and outdoor bulk storage equally. Four sizes range from 225×300 mm for small enclosures to 600×900 mm for large perimeter zones. Reflective Class 1 and Class 2 options boost visibility in low-light conditions. Lamination protects against fuel vapour and weathering. Platinum Signs delivers Australia-wide with bulk discounts for multi-location risk assessments.
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
Where must explosion-hazard signs be positioned?
Place signs at all entry points to explosive atmospheres—doors to solvent storerooms, perimeter fencing around fuel depots, and access gates to grain silos. Position at eye level for immediate visibility.
Will lamination resist fuel and solvent vapours?
Standard lamination resists most petroleum products. For extreme solvent exposure (e.g. acetone, toluene), specify chemical-resistant lamination—contact our sales team for options.
Should I use Class 1 or Class 2 reflective finish?
Reflective grades provide different visibility performance. Choose the grade required by the project specification and site conditions, and confirm any road, traffic or high-risk requirement with the relevant authority before ordering.
Can I order custom text for specific explosive materials?
Yes. We can add material-specific warnings (e.g. 'Petrol Vapours', 'Grain Dust Explosive') to your sign. Provide your hazard details and we'll quote a custom layout.
What bulk discounts apply to petrol station chains?
Volume-pricing examples are 5 signs: 8% off, 10 signs: 15% off, 25 signs: 24% off, 50 signs: 32% off, 100 signs: 40% off. Savings increase gradually between these quantities. The total increases as you add more signs, while the average price per sign falls or stays the same. The configurator calculates the total for your selected quantity.
