Product Overview

Summary: This Safe Operating Procedure sets out a clear, step-by-step method for the safe installation of hydraulic systems on Australian worksites. It helps your team control high‑risk hazards such as stored energy, high‑pressure fluid injection, and crushing injuries, while ensuring installations are compliant, reliable, and ready for commissioning.

Hydraulic systems are the backbone of many Australian industries, from construction and mining to manufacturing, agriculture and transport. Poorly planned or inconsistent installation practices can lead to leaks, component failure, unexpected movement of plant, and serious injuries from high‑pressure fluid injection or uncontrolled release of stored energy. This Hydraulics System Installation Safe Operating Procedure provides a structured, repeatable process that guides workers from pre‑installation planning through to pressure testing and handover, with safety and WHS compliance at its core.

The SOP breaks down complex technical tasks into clear, logical steps that align with Australian legislation and recognised standards. It covers pre‑start inspections, isolation and lockout, hose routing, torqueing of fittings, contamination control, pressure testing, commissioning support, and documentation. By implementing this procedure, businesses can reduce installation errors, protect workers from high‑risk hydraulic hazards, and demonstrate due diligence to regulators, clients and auditors. It also supports consistent training, making it easier to onboard new technicians and maintain high installation quality across multiple sites and projects.

Key Benefits

• Reduce the risk of high‑pressure fluid injection injuries and uncontrolled movement of machinery during installation.
• Ensure hydraulic installations are completed in line with Australian WHS legislation and relevant industry standards.
• Improve reliability and performance of hydraulic systems through correct assembly, contamination control and pressure testing.
• Standardise installation practices across teams, contractors and sites to minimise rework and downtime.
• Provide clear documentation to support training, inductions, incident investigations and regulatory audits.
