Construction sites are classified as hostile environments under AS/NZS 3760, requiring more frequent testing. Our technicians understand the unique hazards of building sites including exposure to moisture, dust, and physical damage to electrical equipment.
Test & Tag for Construction
Overview
Construction sites present some of the most demanding electrical safety environments in New Zealand. Portable power tools, temporary lighting, extension leads, and three-phase equipment are constantly exposed to dust, moisture, physical impact, and rough handling. Under AS/NZS 3760, construction sites are classified as hostile operating environments, which means portable electrical equipment requires testing every 3 months rather than the standard 12-month interval.
Why It Matters
Why Test & Tag Matters for Construction
Construction sites are classified as hostile environments under AS/NZS 3760, requiring 3-monthly testing of all portable electrical equipment.
RCDs (safety switches) on construction sites require daily push-button testing by the user and quarterly operating time testing by a competent person.
Multiple subcontractors often bring their own equipment on site, making asset tracking and compliance management complex.
WorkSafe NZ actively inspects construction sites for electrical safety compliance, and penalties can apply for non-compliance.
A single faulty tool on a construction site can put multiple workers at risk of electric shock or electrocution.
