Product Overview

Summary: This Hydraulic Hose Replacement Safe Operating Procedure sets out a safe, repeatable method for inspecting, isolating and replacing hydraulic hoses on plant and equipment. It helps Australian workplaces control the serious risks of high‑pressure fluid injection, equipment failure and environmental contamination while keeping assets productive and compliant with WHS obligations.

Hydraulic systems are critical to the safe operation of mobile plant, fixed machinery and lifting equipment across construction, mining, agriculture, manufacturing and transport. When hoses fail, the consequences can be severe: high‑pressure fluid injection injuries, uncontrolled movement of plant, dropped loads, fires, environmental spills and costly downtime. This Hydraulic Hose Replacement Safe Operating Procedure provides a clear, step‑by‑step framework for planning, isolating, replacing and testing hydraulic hoses in a way that prioritises worker safety and system integrity.

Developed for Australian workplaces, the SOP aligns with WHS duties to provide safe systems of work and to manage high‑risk plant. It addresses common pain points such as inconsistent replacement practices, inadequate isolation, poor hose routing, and lack of documentation. By implementing this procedure, businesses can standardise how hydraulic hose work is performed across sites and shifts, improve the quality of maintenance, and create a defensible record of risk management. The result is fewer incidents, extended component life, and increased confidence that equipment will perform safely under pressure.

Key Benefits

• Reduce the risk of high‑pressure fluid injection injuries and catastrophic hose failures.
• Ensure consistent, compliant hydraulic hose replacement practices across all sites and shifts.
• Extend equipment and hose life through correct selection, routing, clamping and torqueing.
• Minimise unplanned downtime and costly breakdowns caused by premature hose failure.
• Demonstrate due diligence under Australian WHS legislation with a documented safe system of work.
