Description
This identification sign marks electrical isolators and isolation switches, enabling fast, accurate lockout/tagout (LOTO) procedures during maintenance and emergency shutdowns. Essential in manufacturing, utilities, and facilities where multiple isolation points must be clearly identified to prevent accidental re-energisation. Manufactured in Colorbond steel, polypropylene, or vinyl in two sizes (225×300 mm and 300×450 mm). Pre-drilled mounting holes are standard. Platinum Signs delivers Australia-wide with bulk discounts for trade accounts managing multi-site installations.
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
How does this sign support lockout/tagout compliance?
It clearly identifies isolation points so maintenance teams can quickly locate the correct switch during LOTO procedures, reducing risk of accidental re-energisation.
Can I use this indoors and outdoors?
Yes—Colorbond handles outdoor exposure; vinyl or polypropylene work well in sheltered plant rooms and indoor electrical enclosures.
What size should I choose for a large switchboard?
Available sizes are 225 x 300mm (Small), 300 x 450mm (Medium). 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 supply these to electrical contractors?
Yes, we have trade accounts with flexible ordering and invoice payment terms for licensed electricians and contractors.
How many signs do I need for a typical facility?
That depends on the number of isolation points; contact us with a site plan or equipment list for a tailored recommendation.
