Hazards & Risks Covered

Hazard Risk Description
1. Governance, WHS Duties and PCBU Oversight
  • • Lack of clear allocation of WHS duties for hydraulic maintenance activities leading to gaps in oversight and decision‑making
  • • Failure of officers to exercise due diligence in relation to hydraulic power pack risks (design, inspection, maintenance, competency)
  • • Inadequate WHS policy framework to address high‑risk plant and pressurised hydraulic systems
  • • Poor integration of hydraulic safety requirements into the organisation’s WHS management system and risk register
  • • Inadequate consultation with workers and health and safety representatives (HSRs) about hydraulic system risks and changes
  • • Failure to monitor compliance with WHS Act 2011 and WHS Regulation plant provisions for hydraulic equipment
  • • Insufficient contractor management arrangements for external hydraulic service providers
2. Design, Engineering and Change Management of Hydraulic Systems
  • • Hydraulic power packs and associated systems not designed, verified or selected in accordance with relevant Australian Standards and WHS Regulation plant requirements
  • • Lack of engineering assessment of pressure ratings, hose routing, system redundancy and failure modes leading to potential high‑pressure fluid injection or catastrophic release
  • • Inadequate guarding or separation distances around moving parts, rotating shafts, fans and hot surfaces within the power pack assembly
  • • No formal management of change (MOC) process when hydraulic circuits, pressure settings, components or control logic are modified
  • • Poor integration of emergency stop, interlocks and fail‑safe functions with existing plant control systems
  • • Insufficient consideration of noise, vibration and heat management at design stage impacting worker health and comfort
  • • Inaccessible components, isolation points and test ports leading to unsafe maintenance access arrangements
3. Procurement, Commissioning and Decommissioning of Hydraulic Power Packs
  • • Procurement of hydraulic power packs and components that are not suitable for the intended pressure, duty cycle, fluid type or environmental conditions
  • • Absence of WHS and engineering input during procurement leading to lifecycle safety issues, difficult access and non‑standard components
  • • Inadequate pre‑delivery verification of documentation, conformity, test certificates and safety features
  • • Poorly planned commissioning leading to uncontrolled pressurisation, undetected leaks or malfunctioning safety controls
  • • Lack of structured decommissioning and disposal processes for obsolete hydraulic equipment and contaminated fluids
4. Training, Competency and Authorisation
  • • Maintenance personnel working on hydraulic systems without adequate theoretical and practical knowledge of high‑pressure hydraulics
  • • Supervisors and planners lacking understanding of hydraulic hazards, leading to inadequate task planning and risk control selection
  • • No formal competency framework for hydraulic maintenance, resulting in inconsistent skills and unsafe practices
  • • Lack of specific training on hydraulic power pack OEM instructions, system schematics and isolation procedures
  • • Inadequate refresher training leading to skill fade and complacency
  • • No formal authorisation process to control who can inspect, adjust or modify hydraulic systems
5. Hydraulic Energy Isolation, Lockout and Stored Energy Management
  • • Uncontrolled release of hydraulic energy due to inadequate isolation, lockout or dissipation procedures during maintenance and inspection
  • • Residual stored pressure in accumulators, cylinders, hoses or line sections not identified or managed
  • • Bypassing or defeating isolation devices or interlocks for convenience or due to production pressure
  • • Inconsistent application of lockout/tagout (LOTO) for multi‑energy sources (electrical supply to power pack, hydraulic pressure, potential energy in raised equipment)
  • • Lack of verification (try‑out) steps to confirm absence of pressure before starting maintenance
6. Preventive Maintenance, Inspection and Condition Monitoring
  • • Absence of a structured preventive maintenance (PM) program for hydraulic power packs leading to component failures and sudden loss of containment
  • • Degraded hoses, fittings and seals not identified due to infrequent or informal inspections
  • • Contaminated hydraulic fluid causing accelerated wear, overheating or unpredictable system behaviour
  • • Maintenance tasks performed reactively under time pressure, increasing the likelihood of risk‑taking and errors
  • • Inadequate documentation of defects and corrective actions creating blind spots in asset condition
  • • Failure to recognise early warning signs such as unusual noise, vibration, temperature rises or slow response
7. Documentation, Procedures and Technical Information Management
  • • Maintenance work on hydraulic power packs performed without current procedures, schematics or OEM manuals
  • • Out‑of‑date or conflicting hydraulic circuit drawings leading to incorrect isolation, misconnections or unsafe modifications
  • • Procedures that are overly generic and do not cover specific risks associated with high‑pressure hydraulics and injection injury
