Product Overview

Summary: This Safe Operating Procedure sets out clear, practical requirements for the safe use, handling and storage of chemicals on construction sites across Australia. It helps construction businesses control exposure to hazardous substances, meet WHS obligations, and protect workers, subcontractors and the environment from chemical-related incidents.

Construction sites routinely use a wide range of chemicals, from concrete additives, sealants and solvents to fuels, cleaning agents and hazardous substances such as isocyanate-based products. Without a structured approach, these chemicals can lead to serious health issues, fires, environmental contamination and costly project delays. This Safe Operating Procedure provides a clear framework for identifying hazardous chemicals, understanding Safety Data Sheets (SDS), implementing appropriate controls and managing chemicals throughout their lifecycle on site.

The document translates Australian WHS requirements into practical, site-ready instructions that supervisors and workers can actually follow. It covers planning for chemical use, safe decanting and mixing, labelling and segregation, ventilation and exposure control, spill response, and disposal in line with environmental expectations. By implementing this SOP, construction businesses can standardise their approach across multiple projects, demonstrate due diligence to regulators and clients, and significantly reduce the risk of chemical-related incidents, illnesses and regulatory non-compliance.

Key Benefits

• Ensure consistent, compliant practices for chemical use across all construction sites and projects.
• Reduce the risk of chemical exposure, burns, respiratory illness and long-term health effects for workers.
• Minimise the likelihood of fires, explosions and environmental contamination caused by poor chemical management.
• Streamline induction and on-the-job training by providing clear, step-by-step guidance for everyday chemical tasks.
• Demonstrate due diligence to clients, regulators and auditors through documented, defensible safety procedures.
