Product Overview

Summary: This Spill Containment Procedures Safe Operating Procedure provides a clear, step‑by‑step framework for responding to and managing spills in Australian workplaces. It helps your team contain, clean up, and report hazardous and non‑hazardous spills safely, minimising harm to people, property, and the environment while supporting WHS and environmental compliance.

Spills of chemicals, fuels, oils and other liquids are a common but often under‑managed risk in Australian workplaces. Whether it occurs in a warehouse, workshop, laboratory, depot or on a loading dock, a poorly controlled spill can lead to slips, trips and falls, chemical exposure, fire or explosion, and serious environmental harm. This Spill Containment Procedures SOP sets out a structured, repeatable process for identifying the type of spill, raising the alarm, selecting the right spill kit, containing the spread, safely cleaning up, and disposing of waste in line with Australian regulatory requirements.

The document is designed to translate legislative and code of practice requirements into practical on‑the‑ground actions that workers can follow under pressure. It clarifies roles and responsibilities, defines escalation thresholds (when to call 000, the EPA or external emergency services), and standardises how incidents are recorded and investigated. By implementing this SOP, businesses can demonstrate due diligence under WHS and environmental laws, improve readiness for unplanned events, and significantly reduce the likelihood that a minor spill escalates into a major safety, environmental or reputational incident.
