Air Conditioner Decommissioning Risk Assessment

Product Overview

Identify and control organisational risks associated with Air Conditioner Decommissioning through a structured, management‑level WHS Risk Management framework that focuses on systems, planning and governance rather than task‑by‑task procedures. This Risk Assessment supports executive Due Diligence under the WHS Act, helping to demonstrate compliance, reduce operational liability and protect your business from regulatory and contractual exposure.

Risk Categories & Hazards Covered

This document assesses risks and outlines management controls for:

  • Governance, WHS Duties and Legal Compliance: Assessment of officer due diligence, allocation of WHS responsibilities, compliance monitoring and integration of decommissioning activities into the organisation’s WHS management system.
  • Competency, Licensing and Training Systems: Management of competency requirements for technicians handling refrigerants, electrical isolation and working at heights, including licensing verification, refresher training and competency records.
  • Planning, Design and Engineering Risk Management: Evaluation of decommissioning methodologies, engineering controls, plant selection and design‑stage decisions to minimise risks during removal, transport and disposal of air conditioning units.
  • Hazard Identification, Risk Assessment and Change Management: Systems for pre‑job risk assessments, ongoing hazard reviews, management of variations to scope, and controls for unforeseen conditions in ceiling spaces, plant rooms and external locations.
  • Refrigerant and Hazardous Chemicals Management System: Controls for safe recovery, storage, labelling, transport and disposal of refrigerants and associated chemicals, including leak management, environmental protection and compliance with refrigerant handling regulations.
  • Plant, Tools, Equipment and Maintenance Systems: Management of lifting equipment, recovery units, vacuum pumps, cutting tools and access equipment, including inspection, maintenance, pre‑use checks and equipment suitability for specific decommissioning tasks.
  • Electrical Safety, Isolation and Lock‑Out Systems: Protocols for verification of isolation, lock‑out/tag‑out procedures, coordination with electricians, and prevention of inadvertent energisation during disconnection and removal of air conditioning systems.
  • Site Access, Traffic and Work Environment Management: Assessment of access routes, public interface, vehicle movements, work at heights, confined or restricted spaces, and environmental conditions across commercial, industrial and residential sites.
  • Health Monitoring, PPE and Occupational Hygiene Management: Systems for selection and use of PPE, exposure controls for noise, dust, insulation fibres and chemicals, and health monitoring where required by legislation or risk profile.
  • Emergency Preparedness and Incident Management: Planning for refrigerant leaks, electrical incidents, falls, fire, environmental releases and medical emergencies, including emergency equipment, response procedures and post‑incident review.
  • Documentation, Records, Communication and Consultation: Management of SWMS interfaces, permits, service records, decommissioning certificates, waste tracking, and consultation processes with workers and other duty holders.
  • Contractor Management, Procurement and Outsourcing: Controls for prequalification, selection and monitoring of contractors, clarity of WHS responsibilities in contracts, and assurance that outsourced decommissioning activities meet organisational and legislative requirements.

Who is this for?

This Risk Assessment is designed for Business Owners, Directors, Safety Managers and Project Managers responsible for planning, overseeing and auditing Air Conditioner Decommissioning operations across their organisation or contractor network.

Hazards & Risks Covered

Hazard Risk Description

  • • Inadequate contractor management arrangements where decommissioning is outsourced
  • • Failure to ensure PCBUs in a shared workplace coordinate activities and share relevant WHS information
2. Competency, Licensing and Training Systems
  • • Workers performing refrigerant recovery or electrical isolation without appropriate licences or authorisations
  • • Inadequate verification of competency for technicians undertaking decommissioning of complex systems or high‑pressure refrigerants
  • • Lack of formal induction covering site‑specific WHS risks, emergency procedures and environmental obligations
  • • Insufficient training on correct use, inspection and limitations of tools, test equipment and personal protective equipment (PPE)

3. Planning, Design and Engineering Risk Management
  • • Decommissioning works planned without consideration of structural load paths, access routes or impact on existing building services
  • • Selection of decommissioning methods that do not account for refrigerant type, pressure, flammability or toxicity
  • • Lack of engineering input on safe isolation points, access platforms, lifting points and anchorages
  • • Inadequate assessment of building layout leading to poor emergency egress and restricted access for rescue or evacuation
  • • Failure to identify latent conditions such as asbestos‑containing materials, brittle roofing, deteriorated supports or undocumented modifications to plant
  • • Poor integration of new plant installation plans with decommissioning strategy, causing congestion and conflicting workflows
4. Hazard Identification, Risk Assessment and Change Management
  • • Failure to systematically identify hazards related to refrigerants, electrical energy, stored mechanical energy, working at height and confined spaces during decommissioning
  • • Generic or outdated risk assessments that do not reflect actual site conditions or new types of equipment and refrigerants
  • • Absence of a formal management of change process when plant design, location or decommissioning methodology is altered
  • • Inadequate consideration of interaction between multiple contractors or concurrent tasks within the same area
  • • Poor documentation and communication of identified risks and controls to all affected workers
  • • Lack of review of risk assessments following incidents, near misses or regulatory updates
5. Refrigerant and Hazardous Chemicals Management System
  • • Uncontrolled release of refrigerant to atmosphere during decommissioning due to poor systems or equipment
  • • Inadequate inventory and labelling of refrigerants, leading to confusion between non‑flammable, mildly flammable and flammable types
  • • Lack of procedures for handling contaminated or mixed refrigerants recovered from aged systems
  • • Improper storage, segregation or transport of recovered refrigerant cylinders and associated hazardous chemicals (oils, cleaning agents)
  • • Non‑compliance with environmental protection requirements and refrigerant handling regulations
  • • Insufficient emergency arrangements for refrigerant leaks, including oxygen‑deficient atmospheres and flammable gas accumulation
6. Plant, Tools, Equipment and Maintenance Systems
  • • Use of unsuitable or poorly maintained recovery units, gauges, hoses, vacuum pumps and leak testing equipment
  • • Failure or malfunction of lifting equipment, access equipment and supports used to handle units and components during decommissioning
  • • Inadequate inspection and testing of electrical tools and equipment, increasing risk of electric shock or fire
  • • Lack of standardisation of equipment leading to incorrect connections, fittings or adapters being used
