Description
The Safe Work Procedure Must Be Read and Understood Before Commencing Work sign reinforces procedural compliance using the AS 1319 yellow and black warning format. Positioned at task entry points, equipment stations, or work zones, it ensures workers acknowledge safety requirements before beginning operations—critical for high-risk activities, confined spaces, or specialised equipment use. Manufactured in corflute, polypropylene, Colorbond steel, and vinyl across four sizes, the sign is printed with UV-stable inks that remain legible in harsh Australian conditions. Choose lamination for protection against oils and solvents, reflective Class 1 or 2 striping for low-visibility areas, or pre-drilled holes for tool-free mounting.
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
Why use this sign instead of a generic caution notice?
This sign uses the standardised AS 1319 yellow and black format, which workers instantly recognise as a formal hazard warning. It reinforces that reading and understanding the procedure is a mandatory step, not optional guidance.
Can I laminate the sign to protect it from spills?
Yes. We offer lamination as an optional extra, which adds a protective layer against moisture, oils, and chemical splashes. This extends the sign's life in harsh workshop or factory environments.
What sizes work best for equipment stations?
Available sizes are 225 x 300mm (Small), 300 x 450mm (Medium), 450 x 600mm (Large), 600 x 900mm (Extra Large). Viewing-distance notes are a practical selection aid, not a substitute for checking the approach distance, lighting, mounting position, wording and site risk assessment.
Do you offer bulk discounts for site-wide rollouts?
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.
Is this sign suitable for outdoor construction sites?
Colorbond or UV-resistant vinyl are ideal for outdoor use. Both withstand sun exposure and weather without significant fading. Pair with Class 2 reflective striping if the site operates in low-light conditions.
