Product Overview

Summary: This Rust Prevention and Coating Safe Operating Procedure sets out a clear, safe and consistent method for preparing, treating and coating metal surfaces in Australian workplaces. It helps control exposure to hazardous chemicals, ensures correct surface preparation and application techniques, and supports compliance with WHS and environmental obligations while extending the life of plant, equipment and structures.

Corrosion is a major cost and safety issue across Australian industry, from construction and manufacturing to marine and mining environments. Poorly managed rust prevention and coating work can lead not only to premature asset failure, but also to serious health and safety risks such as solvent exposure, fire and explosion hazards, and falls from height while accessing steel structures. This Rust Prevention and Coating SOP provides a structured, WHS-focused approach to surface preparation, rust treatment, coating selection and application, tailored to Australian conditions and regulatory expectations.

The procedure sets out step-by-step requirements for planning the work, selecting compatible coating systems, preparing surfaces (including mechanical and chemical methods), mixing and applying coatings, and managing curing and inspection. It embeds risk controls for hazardous chemicals, flammable vapours, noise, dust, manual handling and work at height, and clarifies roles and responsibilities for supervisors, applicators and inspectors. By implementing this SOP, businesses can standardise their coating practices across sites, demonstrate due diligence under WHS law, reduce rework and coating failures, and protect both workers and high-value assets from the harsh Australian environment.

Key Benefits

• Ensure consistent, high-quality rust prevention and coating outcomes across all sites and projects.
• Reduce worker exposure to hazardous chemicals, fumes and dust through clearly defined control measures.
• Minimise the risk of fires, explosions and environmental incidents associated with flammable and solvent-based coatings.
• Extend the service life of steelwork, plant and equipment, reducing unplanned downtime and replacement costs.
• Support demonstrable compliance with Australian WHS, hazardous chemicals and environmental requirements.
