Testing and tagging: what you need to know about AS/NZS 3760

When it comes to electrical safety, there is no room for error. That is why testing and tagging your equipment is so important in the construction and mining industries. The testing and tagging process necessitates the use of specialised equipment to assess the electrical safety of equipment and devices. The purpose of testing and tagging is to ensure the safety of all electrical devices and equipment to prevent electrical-related accidents and injuries.

Why an electrical test and tag?

The primary reason for testing and tagging is to ensure the safety of workers who come into contact with the appliance while also reducing the risk of an electrical hazard. The Australian Standard AS/NZS 3760 provides guidelines and regulations for the test and tag industry in terms of the electrical safety of appliances. It defines who can test and tag, as well as general guidelines and makes recommendations on issues such as when they are needed.

What you need to know about AS/NZS 3760

  • Tests need to be carried out by a qualified person, who will also issue the tag.
  • The test involves using a portable appliance tester (PAT) to check the earth continuity, insulation resistance and polarity of the equipment.
  • A visual check is also carried out to make sure that there are no damaged cords or plugs and that the appliance is in good working order.
  • If an item fails its test, it must be repaired or replaced before it can be used again.
  • Tagged appliances should be regularly tested to make sure they are still safe to use.
  • A logbook should be kept of all tests that have been carried out.

Since the work is considered high-risk, construction and mining companies are required to have their appliances tested and tagged every three months. This is because these industries frequently work with live electrical equipment and in potentially hazardous environments, which can increase the risk of an electrical incident. It is also because of the harsh nature of the industry which is likely to damage equipment at a faster rate. 

What equipment is tested? 

Any electrical appliance on-site, such as tools, battery chargers, cleaning equipment, extension leads and portable RCD boxes, will need to be tested. This is particularly important for high-risk industries to ensure that all equipment is safe to use.

What are the benefits of testing and tagging? 

The benefits of testing and tagging are that it helps to ensure the safety of employees and also reduces the risk of electrical incidents on-site. Testing and tagging also help to prolong the life of electrical equipment by ensuring that it is in good working order.
