Rope access inspection inside industrial tanks and silos combines two of the highest-consequence work categories recognised under Australian WHS law: work at height by suspended rope and entry into a confined space with potentially hazardous atmospheres. Inspectors descend into vertical cylindrical vessels — grain silos, fuel tanks, process reactors, water reservoirs — to assess corrosion, weld integrity, coating condition or residual product, often with limited natural light, restricted egress and oxygen-deficient or flammable atmospheres. This work is High Risk Construction Work under WHS Regulation 2011 r291 (work at height >2m and confined space entry), and a Safe Work Method Statement is mandatory before commencement and must be kept on site, available to regulators and workers, and reviewed if conditions change. This SWMS template documents the systematic hazard identification, control selection, atmospheric monitoring regime, rescue plan and sign-on process required to discharge the PCBU's primary duty of care under s19 of the WHS Act.
Hazards identified
7 hazards covered, sorted by priority.
Rapid loss of consciousness within seconds, asphyxiation, fall-arrest suspension trauma compounding hypoxia, fatality before rescue
Acute chemical pneumonitis, explosion on ignition source, chronic neurological injury, prosecution under s32 reckless conduct
Venous pooling, orthostatic shock, cardiac arrest within 10-30 minutes if casualty not retrieved horizontal
Uncontrolled fall to vessel floor, multiple fractures, traumatic brain injury, fatal impact from heights exceeding 10 metres
Burial within seconds, mechanical asphyxiation, crush injury, body recovery rather than rescue outcome
Rescue delay beyond survivable window, secondary rescuer fatality, breach of confined space rescue plan requirements
Dehydration, heat exhaustion, impaired judgement leading to descent errors, heat stroke requiring hospitalisation
Control measures
Hierarchy-of-controls order: elimination → substitution → isolation → engineering → administrative → PPE.
- 1Elimination — Use remote inspection technologies (drone, crawler, borescope, LiDAR) deployed through the top manway to eliminate the need for human entry where defect detection criteria can be met visually.
- 2Elimination — Schedule inspection during planned shutdown after full product evacuation, mechanical cleaning and atmospheric purge so no residual hazardous material remains in the vessel.
- 3Substitution — Replace single-rope descent with twin-rope IRATA Level 3 system using independent anchors so no single component failure can result in a fall.
- 4Engineering — Install certified structural anchor points rated to AS/NZS 5532 minimum 15kN, independently load-tested and tagged within 12 months prior to use.
- 5Engineering — Continuous atmospheric monitoring with calibrated 4-gas detector (O2, LEL, CO, H2S) bump-tested pre-entry, with audible alarms set per AS/NZS 2865 confined space limits.
- 6Engineering — Mechanical ventilation supplying minimum 20 air changes per hour through dedicated inlet and exhaust ducts, maintained throughout the entire entry duration.
- 7Administrative — Issue and sign Confined Space Entry Permit per AS/NZS 2865 specifying duration, atmospheric results, standby person, rescue plan and authorised entrants before each entry.
- 8Administrative — Dedicated trained standby person at manway maintaining continuous voice and visual contact, with hauling system pre-rigged for vertical retrieval within 4 minutes.
- 9Administrative — Pre-start SWMS sign-on briefing covering rescue triggers, communication signals, atmospheric alarm response and emergency self-rescue procedures with all entrants.
- 10PPE — Full body harness AS/NZS 1891.1 with suspension trauma straps, supplied-air respirator or SCBA AS/NZS 1716, hard hat with chin strap, intrinsically safe lighting and gas detector worn in breathing zone.
Applicable Codes of Practice
Mandates entry permit system, atmospheric testing regime, standby person and rescue arrangements directly applicable to every tank and silo entry under this SWMS.
Specifies twin-rope requirements, anchor standards, operator competency and supervision ratios governing the rope access component of the inspection work.
Sets the regulator's expected risk management process for confined space work including hierarchy of control application and rescue plan documentation.
Governs harness inspection intervals, suspension trauma response and connector compatibility relied upon for the fall-arrest backup system during descent.
High-Risk Construction Work triggered
Inspectors descend on rope from the vessel roof to floor, routinely exceeding 2 metres and often 10-30 metres inside silos and storage tanks.
Tank and silo interiors meet the AS/NZS 2865 confined space definition — enclosed, not designed for human occupancy, with restricted entry and potential atmospheric hazards.
Residual product vapours, oxygen displacement from rust or inert purges and dust loading routinely produce atmospheres below or above safe contaminant thresholds during entry.
PCBUs must prepare, consult workers on, and retain this SWMS for the duration of the work plus two years after any notifiable incident; penalties for non-compliance are substantial and indexed annually to the prevailing WHS schedule.

Worked example
A two-person rope access team is scheduled to inspect the internal coating of a 22-metre regional bulk fuel storage tank following decommissioning of the product line. At the pre-start brief on site, the supervisor opens this SWMS on a ruggedised tablet and walks both technicians and the standby person through each row of the hazard register. When they reach the atmospheric hazard line, the standby person notes that the tank has only been ventilated overnight, not the recommended 48 hours; the team pauses, runs the 4-gas detector through the manway on a sample line, and records 18.9% oxygen — below the 19.5% entry threshold in AS/NZS 2865. Following the SWMS control hierarchy, they escalate ventilation by adding a second blower and delay entry by 90 minutes until readings stabilise at 20.8% O2, 0% LEL. The Confined Space Entry Permit and SWMS sign-on sheet are then completed, with each entrant initialling the rescue plan section confirming they understand the hauling system is rigged and the standby person retains voice contact every two minutes. Mid-task, the lead technician identifies unexpected sludge pooling at the floor not noted in the scope; he ascends, the supervisor amends the SWMS with the new engulfment control, both workers re-sign, and work resumes safely.
