Description
Safe Operating Procedure (SOP) signs reinforce critical work instructions and reduce injury risk by reminding operators of correct techniques. Compliant with AS 1319, these warning signs use the yellow and black triangle to flag procedural hazards in manufacturing, maintenance, and technical environments. Supplied in corflute, polypropylene, Colorbond, or vinyl across 225×300 mm to 600×900 mm. UV-stable inks ensure long-term legibility outdoors and in harsh conditions. Reflective Class 1 and Class 2 upgrades available for night-shift visibility. Platinum Signs delivers nationwide to trade accounts with competitive bulk rates.
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 SOP signs in addition to training?
Yes, SOP signs serve as ongoing visual reminders after initial training. They're particularly valuable for shift changes, new staff, and high-risk tasks where muscle memory can lapse.
What size should I use for machinery 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.
Can I add specific procedure text to the sign?
Our standard range uses AS 1319 approved symbols. Custom SOP text is available—contact our design team with your procedure details and we'll provide a quote and sample.
How often do signs need replacing?
Laminated signs typically last 3–4 years in industrial environments. Unlaminated corflute may need replacement after 2 years if heavily soiled or in direct sun. Colorbond steel lasts 5+ years.
What's the lead time for custom SOP designs?
Standard designs ship in 5–7 business days. Custom designs usually take 10–14 days depending on complexity. We'll confirm timelines when you request a quote.
