What Do Test & Tag Colours Mean? A Simple Guide for Brisbane Businesses
If you've ever looked at an electrical tag on a power tool or appliance at work and wondered what the colour actually means, you're not alone. A lot of people in Brisbane workplaces see those small tags and have no idea what information they carry. This guide breaks it all down in plain language.
Why Does Tag Colour Matter?
In Australia, test and tag is governed by AS/NZS 3760, the national standard for the inspection and testing of electrical equipment. Under this standard, every piece of portable electrical equipment that gets tested needs a tag attached showing when it was last tested and when it's due again. The colour of that tag is what tells you at a glance whether it's current or overdue.
The colour system rotates every three months throughout the year, so anyone doing a visual check on-site can quickly see whether a piece of equipment is within its testing period. This is particularly important in high-risk environments like construction sites, workshops, and offices where electrical faults can cause serious injury or worse.
The Four Main Tag Colours in Queensland
All tag and test work in QLD follows the colour rotation set out in AS/NZS 3760. The four colours used are red, green, blue, and yellow, and they rotate through the year in three-month blocks. Here's what each one means:
Red Tag - December, January, February
A red tag means the equipment was tested in the last quarter of the year or over the summer period. If you're seeing red tags on site in Brisbane right now and it's January, that's a good sign those items were tested recently. Red is the colour for the hottest part of the year, which is also when outdoor and construction work tends to ramp up across South East Queensland.
Green Tag - March, April, May
Green tags cover the autumn months. Equipment tested in March, April, or May will carry a green tag for that testing cycle. In offices and commercial buildings around Brisbane, green tags are commonly seen during the cooler months when businesses often schedule their routine testing to avoid disruption over the Christmas and summer period.
Blue Tag - June, July, August
Blue tags are for the Queensland winter months. While Brisbane winters are pretty mild compared to the rest of the country, testing activity is still just as important. Equipment in hospitality venues, retail stores, and warehouses all needs to stay compliant year-round. A blue tag tells you it was checked over the June to August period.
Yellow Tag - September, October, November
Yellow tags cover the spring quarter. September through November is a busy time across Brisbane's construction, trade, and events industries as warmer weather kicks in and projects ramp up before Christmas. Equipment tested in this window carries a yellow tag to show it's been checked for that period.
What About Construction Sites and Higher Risk Environments?
The same four colours apply across construction, demolition, and mining environments in Queensland, but the testing frequency is much higher. In these industries, equipment needs to be tested every three months rather than every 12 months. That means the tag colour changes every quarter, and you'll see all four colours cycle through within a single year on a construction site.
This is why it's important not to judge testing compliance just by colour alone. You need to check the date on the tag itself to confirm the equipment is still within its testing window. If the date has passed, the equipment should be taken out of service and re-tested before anyone uses it again.
What Information is on a Test Tag?
Beyond the colour, a properly attached test tag will also show the date of testing, the date the next test is due, the name or ID number of the person who carried out the test, and whether the equipment passed. Some tags also include the asset number of the item itself.
If you come across equipment where the tag is missing entirely, or where it's there but has no date information, treat it as untested. Under Queensland workplace health and safety obligations, your employer has a duty to ensure equipment is safe before it's used. A missing or expired tag is a red flag that should be raised with your site supervisor or safety officer straight away.
How Often Does Equipment Need to Be Tested in Brisbane?
Testing frequency depends on the type of environment the equipment is used in. AS/NZS 3760 sets out recommended intervals, and in QLD these are generally followed as guidelines. For most office environments, the standard interval is 5 years for double-insulated equipment and 12 months for other types. For environments like workshops, hire equipment, and commercial kitchens, testing is typically required every 6 to 12 months. For construction, demolition, and mining, it's every 3 months.
It's also worth noting that testing frequency can be increased if there's reason to believe equipment has been damaged or exposed to conditions that could affect its safety. Employers and business owners are ultimately responsible for making sure their equipment is tested at the right intervals.
