Product Overview

Summary: This Surface Decontamination Safe Operating Procedure sets out a clear, step-by-step method for safely cleaning and decontaminating work surfaces, tools and equipment in Australian workplaces. It helps control infection risks, chemical residues and cross‑contamination, supporting WHS compliance while maintaining a clean, professional and safe environment for workers, visitors and contractors.

Effective surface decontamination is a critical control measure for preventing the spread of infectious agents, managing chemical residues and maintaining hygienic work environments across Australian workplaces. From healthcare and aged care facilities to laboratories, food production, offices and construction site amenities, contaminated surfaces can quickly become a significant WHS and reputational risk if they are not managed in a consistent, documented and auditable way. This Surface Decontamination Safe Operating Procedure provides a structured, evidence‑based approach that defines exactly how, when and by whom surfaces must be cleaned and decontaminated.

The SOP translates WHS and infection control requirements into practical, easy‑to-follow steps that workers can apply on the job. It covers selection and safe use of cleaning and disinfectant products, preparation of the work area, segregation of contaminated zones, correct contact times, waste handling and verification of cleaning effectiveness. By implementing this procedure, organisations can reduce variability in cleaning practices, demonstrate due diligence to regulators and clients, and protect workers from exposure to biological and chemical hazards. The document is designed to integrate with existing WHS systems, risk registers and training programs, supporting a defensible and auditable approach to surface hygiene and decontamination.

Key Benefits

• Reduce the risk of infection transmission and cross‑contamination from contaminated surfaces in the workplace.
