Hazards & Risks Covered

Hazard Risk Description
1. Governance, Legislation and WHS Management System Integration
  • • Lack of a documented WHS management system covering compressed air equipment, resulting in ad‑hoc decisions and non-compliance with WHS Act 2011 and WHS Regulations
  • • Absence of clear roles, responsibilities and accountability for air compressor and air receiver safety (PCBUs, officers, workers, contractors)
  • • Failure to identify the air compressor and associated air receivers as plant and, where applicable, as pressure equipment requiring registration and inspection
  • • Inadequate consultation with workers and health and safety representatives on compressor-related risks, procedures and changes to plant layout or compressed air systems
  • • No formal process for reviewing incidents, near misses and audit findings related to compressed air systems, leading to repeat failures
  • • Insufficient integration of compressed air risk controls into broader site policies (e.g. isolation/LOTO, confined space, working at height, hazardous chemicals, noise management)
2. Procurement, Design and Installation of Air Compressors, Air Receivers and Compressed Air Lines
  • • Purchasing compressors or receivers that are not fit for purpose, non-compliant with relevant Australian Standards or unsuited to the site’s pressure, volume or environmental conditions
  • • Lack of engineering review of compressed air system design, resulting in undersized or poorly supported air lines, excessive pressure drops, or unsafe layouts near ignition sources or traffic routes
  • • Failure to specify and procure appropriate pressure relief valves, automatic drains, isolation valves and safety interlocks for air receivers and main distribution lines
  • • Improper siting of air compressors and receivers (e.g. poorly ventilated areas, near combustible materials, pedestrian thoroughfares or vehicle traffic) increasing risk of overheating, fire, noise exposure or impact damage
  • • Use of incompatible materials (e.g. non-rated plastic pipework for compressed air) leading to potential catastrophic burst or fragmentation
  • • Inadequate provision for maintenance access, safe isolation, and emergency shutdown during installation, leading to unsafe future work on the system
3. Asset Registration, Compliance and Air Receiver Management
  • • Failure to register air receivers or pressure equipment with the regulator where required, resulting in regulatory non-compliance and lack of external oversight
  • • No formal inventory of all air receivers and pressure vessels on site, including portable units, leading to missed inspections and uncontrolled ageing of equipment
  • • Inadequate pressure rating identification on receivers and lack of clear labelling of maximum allowable working pressure (MAWP), test dates and inspection status
  • • Uncontrolled modifications or repairs to receivers or safety devices (e.g. welding, relocation of nozzles, plugging of relief valves) without engineering assessment by a competent person
  • • Operation of air receivers beyond design life, outside design conditions or with compromised corrosion allowance due to internal rust, condensate or contamination
  • • No documented system for isolating, depressurising and tagging out receivers for inspection, internal entry (where applicable) or decommissioning
4. Inspection, Testing and Preventive Maintenance Systems
  • • Lack of scheduled preventive maintenance and statutory inspections for compressors, air receivers and safety devices, leading to undetected defects or deterioration
  • • Inconsistent or informal approach to carrying out compressor checks, resulting in missed early-warning indicators (e.g. abnormal noise, temperature, vibration, pressure fluctuations)
  • • Failure of pressure relief valves, gauges, automatic drains or other critical safety components due to lack of testing or calibration
  • • Maintenance and inspection tasks undertaken by untrained or unqualified personnel, increasing the risk of incorrect work and latent failures
  • • Poor recordkeeping of inspections, test results, repairs and replacements, leading to inability to demonstrate compliance or track trends
  • • Substitution of non-genuine or incompatible parts during maintenance, affecting reliability and safety integrity of the compressed air system
5. Operating Procedures, Safe Systems of Work and Carrying Out Compressor Checks
  • • Absence of formal operating procedures for starting, running, loading/unloading and shutting down compressors and associated plant, leading to inconsistent practices
  • • Compressor checks being carried out without defined safe limits, isolation steps or escalation criteria, increasing the risk of operation with known defects
  • • Uncontrolled use of compressed air for cleaning clothing, skin or equipment, leading to injection injuries, eye damage or dislodged debris
