Construction and Demolition Test and Tag Colour Guide
For businesses working in the construction and demolition industry, they are required to use particular tag colours for different months of the year as specified by the AS/NZS 3012 standard. These colours are referred to as RGBY representing the red, green, blue and yellow colours.
- Red Tag: for the months of December, January and February
- Green Tag: for the months of March, April and May
- Blue Tag: for the months of June, July and August
- Yellow Tags: for the months of September, October and November

It is recommended that you test your item or items at the beginning of the colour change so that you can get three months out of your tag. If you get an item tested just three weeks before the colour change, you will have to get it re-tested as soon as the new colour months start. You can get professional help and guidance from The Local Guys if you are still confused about the colouring system.
Other Business Test and Tag Colours
For businesses operating outside of the construction and demolition industries, there are no legislative requirements dictating specific colour coding requirements for particular months. This means you have the freedom to select your colour tag colour based on your personal preferences.

How often should you get your electrical equipment tested and tagged?
The frequency of the testing and inspection of the electrical equipment can vary from three months to six months to a year, two years or even five years. It all depends upon the environment in which the appliances are working. The Australian Standard AS/NZS 3760:2022 advises the following frequencies according to the application and industry in which the appliances are operating:
- Construction, demolition, and mining sites: 3 months for the portable RCDs and appliances
- Commercial kitchen, production houses, commercial cleaning, warehouses, and factories: 6 months for the appliances and push-button test for the fixed RCDs
- Non-commercial kitchens, bathrooms, common spaces, and meeting rooms: 12 months for the equipment whose supply cord is flexed or abused. Operating time test for the Fixed RCDs.
- Hotels, accommodation houses, hostels, halls, etc.: 24 months for appliances and RCDs.
- Fixed office equipment, security systems, server racks, communication racks: 60 months for appliances where the cord isn’t abused or flexed.

The workplaces and industries other than the construction, mining, and demolition industries must use a risk management approach to schedule their test and tag services at the right time. This will help them determine the right time and the right inspection to determine whether testing is required.
