Product Overview

Summary: This SOP provides a clear, step-by-step process for safely disinfecting workplaces following a suspected or confirmed viral outbreak. It helps Australian businesses control infection risks, protect workers and visitors, and demonstrate due diligence under WHS legislation and public health directions.

Viral outbreaks such as influenza, gastroenteritis, COVID-19 and other communicable diseases can spread rapidly through workplaces, leading to illness, absenteeism, reputational damage and potential regulatory scrutiny. This Disinfection After Viral Outbreak Safe Operating Procedure sets out a structured, evidence‑informed approach for assessing affected areas, isolating and cordoning spaces, selecting appropriate disinfectants, and carrying out thorough decontamination while safeguarding workers and building occupants. It is designed to integrate smoothly with existing WHS risk management processes and business continuity plans.

Developed specifically for Australian workplaces, the SOP translates public health guidance and WHS duties into practical, on-the-ground actions that cleaning teams, supervisors and managers can consistently follow. It removes guesswork by defining when and how to escalate cleaning, what PPE is required for different levels of risk, how to manage waste and laundry, and how to safely re‑open areas after disinfection. By implementing this procedure, organisations can respond quickly and confidently to viral outbreaks, reduce the risk of secondary transmission, and provide clear documentation of the controls in place to protect workers, clients and visitors.
