Warning signs alert workers to hazards that could cause injury or illness if not avoided. Recognised by their yellow and black colour scheme under AS/NZS 1319, warning signs cover a broad range of moderate workplace hazards found across Australian industries.
Industro supplies AS/NZS 1319 compliant warning signs to businesses across construction, manufacturing, logistics, mining, and retail. Our range includes standard stock signs for the most common hazard scenarios, with custom options available for site-specific requirements.
Common warning sign applications
- Slippery surfaces and wet floors
- Forklift and vehicle operating areas
- Overhead lifting and crane zones
- Uneven ground and trip hazards
- Noise hazard areas requiring hearing protection
- Chemical splash and spill risk areas
- Low clearance and height restrictions
Warning signs under AS/NZS 1319
The standard requires warning signs to use a yellow background with a black triangle and symbol, clearly describing the nature of the hazard. The format is consistent across all compliant warning signs so workers can identify the hazard type at a glance.
Warning signs are a key part of your WHS risk management framework. Where a hazard cannot be eliminated or engineered out, signage is the final administrative control that keeps workers informed.
Why buy from Industro
Our warning signs are made for Australian conditions. They are UV-stable, weatherproof, and designed to remain legible after years of outdoor exposure. Stock items ship the same day from our Australian warehouse. Custom signs and bulk orders are quoted on request.
What is the difference between a warning sign and a caution sign?
In AS/NZS 1319, warning signs and caution signs serve slightly different purposes. Warning signs indicate a hazard that could cause serious injury. Caution signs indicate a lower-level hazard or unsafe practice. Both use yellow but have distinct formats under the standard.
Do I need warning signs if I already have guards on machinery?
Yes. Even where physical guards are in place, warning signs are required to alert workers to residual risks and to satisfy WHS inspection requirements. Signage and physical controls work together, not instead of each other.
