Product Overview

Summary: This Refrigerant Handling and Disposal Safe Operating Procedure sets out clear, legally defensible steps for safely managing refrigerants from receipt and use through to recovery and end‑of‑life disposal. It helps Australian businesses protect workers, prevent environmental harm, and comply with WHS and refrigerant legislation when working with ozone‑depleting and synthetic greenhouse gases.

Refrigerants are tightly regulated in Australia due to their potential to cause serious health effects, fire and explosion, and long‑term environmental damage if mishandled. This Refrigerant Handling and Disposal SOP provides a structured, step‑by‑step method for safely decanting, charging, recovering, storing, transporting and disposing of refrigerants used in air conditioning, refrigeration and heat pump systems. It is designed to support technicians and supervisors in managing the full refrigerant lifecycle, from initial system work through to recovery into approved cylinders and transfer to licensed waste facilities.

The procedure goes beyond generic safety guidance by integrating WHS risk controls with the specific obligations that apply under the Ozone Protection and Synthetic Greenhouse Gas framework and state‑based dangerous goods requirements. It addresses practical issues such as preventing venting to atmosphere, managing mixed or contaminated refrigerant, working in confined or poorly ventilated plant rooms, and documenting cylinder movements and disposal. By implementing this SOP, businesses can standardise work practices across teams, reduce incident risk, and demonstrate due diligence to regulators, clients and insurers.

This document is particularly valuable for organisations with multiple sites or contractors, where inconsistent practices can lead to leaks, near misses, or non‑compliance. It gives your workforce a clear, accessible reference that supports training, toolbox talks and field supervision, while giving management confidence that refrigerant handling and disposal are being managed in line with Australian best practice.

Key Benefits

• Ensure compliance with Australian WHS laws and refrigerant management requirements, including the prohibition on venting to atmosphere.
• Reduce the risk of asphyxiation, frostbite, chemical exposure and fire by applying consistent safe work methods for handling and transferring refrigerants.
• Minimise environmental impact and potential penalties by standardising recovery, storage, transport and disposal of used or contaminated refrigerant.
• Streamline technician training and onboarding with a clear, repeatable procedure for refrigerant work across all sites and contractors.
• Improve documentation and traceability of refrigerant movements, supporting audit readiness and sustainability reporting.

• Over‑pressurisation and rupture of cylinders, hoses or system components
• Fire and explosion risks with flammable refrigerants (e.g. hydrocarbons, A2L and A3 refrigerants)
• Chemical exposure to refrigerant oils, additives and decomposition products
• Environmental harm from uncontrolled leaks or deliberate venting of ozone‑depleting substances and synthetic greenhouse gases
• Manual handling injuries associated with moving and loading refrigerant cylinders and recovery units
• Slips, trips and falls arising from poor housekeeping around refrigerant handling areas and plant rooms
• Electrical hazards when working on or near energised refrigeration and air conditioning equipment
• Transport and storage risks associated with carrying pressurised cylinders in vehicles or plant rooms
