Product Overview

Summary: This SOP provides a structured, WHS-aligned framework for training workers in the safe and effective use of digital HVAC control systems. It standardises how staff are inducted, authorised and monitored when operating building management systems, helping Australian businesses protect people, assets and critical climate-control infrastructure.

Digital HVAC control systems and building management systems (BMS) are now central to how Australian workplaces manage comfort, air quality, and energy use. When these systems are adjusted incorrectly or accessed by untrained personnel, they can create safety risks, disrupt critical environments, and lead to significant energy and maintenance costs. This Safe Operating Procedure sets out a clear, repeatable process for training, assessing and authorising staff who interact with digital HVAC controls, ensuring only competent personnel make changes that affect building conditions and occupant safety.

The SOP guides organisations through defining competency requirements, delivering structured training modules, conducting practical assessments, and maintaining training and access records in line with WHS obligations and plant safety requirements. It addresses the specific risks associated with remote access, automation overrides, alarms management, and integration with fire and essential services systems. By implementing this SOP, businesses can demonstrate due diligence, support safe system operation, and provide a defensible framework for both day-to-day control and incident response involving digital HVAC controls.

Key Benefits

• Ensure only trained and competent personnel access and adjust digital HVAC and BMS controls.
• Reduce the risk of unsafe temperature, ventilation and pressure conditions that could impact occupant health and critical processes.
• Standardise training content and assessment across sites, improving consistency and compliance with WHS and plant safety requirements.
• Strengthen cyber-physical security by controlling user permissions, remote access and change management for HVAC control systems.
• Improve energy performance and system reliability by preventing inappropriate setpoint changes and control overrides.

• Compromised pressure control in critical areas (e.g. healthcare isolation rooms, laboratories, clean rooms)
• Failure of HVAC integration with fire and smoke control systems due to incorrect programming or manual overrides
• Unplanned plant start-up or shutdown from improper use of digital controls
• Increased risk of Legionella and other biological hazards from poorly managed temperature and circulation regimes
• Electrical and plant maintenance hazards arising from uncoordinated changes to control strategies
• Cybersecurity and unauthorised access to building systems leading to unsafe operating conditions
