Electrical Testing & Tagging
What is Test & Tagging?
Testing & Tagging is the process of inspecting and electrically testing portable and fixed appliances, then tagging them for safety. It provides a snapshot of safety at a moment in time under the standard AS/NZS 3760.
Why It Matters for Your Business
Ensures electrical equipment is safe and reduces risk of electrocution, fire, or damage.
Helps you comply with your duties under the Health & Safety at Work Act 2015 and the Electrical (Safety) Regulations 2010.
Avoids costly downtime if equipment fails unexpectedly.
Test & Tag Frequency Guidelines
Environments like construction sites, workshops, or outdoor use: every 3-6 months.
Offices, retail spaces, less exposed environments: every 12 months or as per risk assessment.
Full inspection & testing of appliances, leads, tools, power boards etc.
Tagging with details: safety status, next test date, who tested.
Advice on test intervals according to environment (office, workshop, wet/damp, construction site).
