Product Overview

Summary: This SOP sets out clear, practical electrical safety requirements for HVAC technicians working on air conditioning, refrigeration and mechanical services in Australian workplaces. It provides a step‑by‑step framework for isolating, testing and working on or near electrical components, helping businesses prevent shocks, arc flash incidents and equipment damage while demonstrating compliance with WHS obligations.

HVAC technicians routinely work on equipment that combines electrical, mechanical and refrigeration hazards, often in ceiling spaces, plant rooms and rooftops where access is restricted and visibility is poor. Without a clear, consistent approach to electrical safety, the risk of electric shock, arc flash, fire and falls from height increases significantly—particularly during fault-finding, commissioning, and after-hours call-outs. This Electrical Safety for HVAC Technicians SOP provides a detailed, task-focused process for planning, isolating, testing, and restoring power to HVAC systems in line with Australian WHS and electrical safety expectations.

The document translates legal and technical requirements into practical field procedures tailored to HVAC work, including split systems, VRF/VRV systems, packaged units, chillers, pumps, fans and associated controls. It outlines how technicians must verify isolation before removing covers, how to safely work in switchboards and control panels within their competency, and when to engage a licensed electrician. It also addresses working in ceiling spaces, on rooftops and in plant rooms where multiple circuits, other trades and environmental factors can complicate electrical risks. By implementing this SOP, businesses can standardise safe work practices across their service and installation teams, reduce incident rates, improve training outcomes, and demonstrate that they have a defensible, documented system of work for electrical safety in HVAC operations.

Key Benefits

• Reduce the risk of electric shock, arc flash and electrical fires during HVAC installation, service and repair activities.
• Ensure HVAC technicians follow a consistent lockout–tagout and test‑before‑touch process that aligns with Australian WHS expectations.
• Strengthen compliance with electrical safety duties under state and territory WHS legislation and relevant Australian Standards.
• Improve onboarding and refresher training by providing technicians with a clear, field-ready reference for safe electrical practices.
• Minimise equipment damage, rework and downtime caused by incorrect isolation, unsafe testing methods or inadvertent energisation.
