Product Overview

Summary: This Compressed Air System Safe Operating Procedure sets out clear, practical steps for safely operating, maintaining, and isolating compressed air systems in Australian workplaces. It helps you manage high-pressure hazards, protect workers from serious injury, and demonstrate due diligence under WHS legislation.

Compressed air is widely used across Australian workshops, manufacturing plants, food processing, mining, and service facilities, but it is often misunderstood as “harmless” compared to other energy sources. In reality, compressed air systems can cause serious injuries, equipment failures, and costly downtime when not managed correctly. This Safe Operating Procedure provides a structured, step-by-step approach for safe operation, inspection, isolation, depressurisation, and basic fault response for fixed and portable compressed air systems.

The SOP is designed to help businesses integrate compressed air safety into their broader WHS management system. It addresses common risk areas such as hose and fitting failures, unsafe use of compressed air for cleaning, noise exposure, stored energy release, and interaction with other plant and processes. By implementing this procedure, organisations can standardise how workers interact with compressors, receivers, piping, and air tools, ensuring consistent training, clear responsibilities, and documented controls that align with Australian WHS legislation and relevant standards.

Key Benefits

• Ensure safe and consistent operation of compressors, receivers, and air distribution systems across all shifts and sites.
• Reduce the risk of high-pressure injection injuries, flying debris, and uncontrolled hose movement.
• Demonstrate compliance with WHS legislation and Australian Standards for pressure equipment and plant safety.
• Standardise training and competency requirements for workers using compressed air systems and tools.
• Minimise unplanned downtime and equipment damage through structured pre-start checks and maintenance practices.
