What the Permit Actually Authorises
A confined space entry permit is a written authorisation, signed before anyone goes in, that ties one identified space to one named crew, one scope of work and a fixed window of time. It records the hazards, the isolations, the gas readings and the rescue arrangements. It is not paperwork completed afterwards, not a site induction, and not a replacement for the written risk assessment that produces it.
The regulatory definition of a confined space turns on a space that is enclosed or partially enclosed, is not designed or intended primarily to be occupied by a person, and presents a risk from an unsafe oxygen level, a harmful airborne contaminant, a flammable atmosphere or engulfment. A tight opening is not part of that test, so permitting every tank and pit drains the authority out of the system — and wrongly declaring a space “not confined” removes every control the permit was carrying.
Before any of that, the Commonwealth WHS (Confined Spaces) Code of Practice 2015 requires entry to be eliminated where that is reasonably practicable: the permit is the last resort, not the default. If the reading can be taken with a camera or the valve reached from outside, there is no permit to write.
The Hazards a Permit Controls
Oxygen can be displaced by purge gas, consumed by rust and fermentation, or enriched by a leaking cutting set. Residues from prior contents give off flammable vapour or hydrogen sulphide. Free-flowing solids and liquids engulf. The opening that let a worker in is often too small to get an unconscious one out.
Heavy vapour sits in the bottom of a silo and light gas collects at the crown, so a sample drawn at the manhole lip tells you about the manhole lip. Sample top, middle and bottom, give the pump and tubing time to purge, and record what the instrument said rather than what was expected.
Which Regulations Apply in Your State?
Confined space entry sits in Part 4.4 of the harmonised WHS Regulations — regs 62 to 77 — adopted in every state and territory except Victoria, which runs the equivalent duties through Part 3.4 of its OHS Regulations 2017. Each regulator backs the regulations with an approved Confined Spaces Code of Practice, and following that code is the accepted way to discharge the duty, which is why inspectors treat it as the benchmark. Because each jurisdiction gazettes its own version with local variations, the operative document on any job is your state regulator’s current edition — section numbering differs even where the substance is identical.
Fields That Make a Permit Valid
Safe Work Australia’s model Code of Practice: Confined Spaces requires the permit to identify the space, the persons permitted to enter, the period of entry, the hazards and the control measures in place, and to be signed by the person who issued it; its appendix carries a sample permit worth holding your own form against.
In a usable permit those headings become specifics: the asset tag and exact location, not “the tank”; a start time and a hard expiry; each hazard with the control that answers it; the isolation points and how each was verified; the gas readings with the instrument serial number and its calibration date; every entrant by name; and the number of standby persons required — which WorkSafe WA’s Confined Space audit template checks alongside a maintained record of who is inside the space. Cross-reference any overlapping hot work, electrical isolation or excavation permit by number so one authority cannot quietly undo another.
The technical benchmark the codes call up is AS 2865-2009 Confined spaces, published by Standards Australia and currently listed as pending revision, so check for a newer edition before you quote clause numbers in your own procedure. Holding your form against what actually happens at the hatch is the work of a confined space entry audit; where the gap is the wider permit system or the gear itself, ask for a Site Safety Audit or an Equipment Inspection instead.

How a Compliant Entry Runs
- Assess and plan. A competent person completes the written risk assessment, identifies the isolations and settles the rescue method. The permit is the output of that assessment.
- Isolate and verify. Lock out and tag every energy source, blank or blind the lines, drain and de-pressurise, and mechanically isolate agitators and augers — then prove the isolation rather than assuming it.
- Ventilate and test. The WHS Regulations define a safe oxygen level as a minimum of 19.5% and a maximum of 23.5% oxygen by volume. SafeWork SA’s Confined Spaces Code of Practice 2020 manages airborne contaminant concentrations against the relevant workplace exposure standards and keeps flammable gas, vapour or mist below 5% LEL while work proceeds — at 5% or more but under 10% LEL, work may continue only with continuous monitoring in the space and ignition sources controlled, and test instruments must be calibrated or bump-tested immediately before use. Test oxygen first, then flammables, then the toxics the space’s history suggests, and keep mechanical ventilation running; an open lid is not a control.
- Issue and enter. The issuer signs, entrants sign on, and the standby person stays outside for the whole entry with continuous communication, never enters the space, and is the one who initiates rescue.
- Monitor and close. Monitoring continues during occupancy. A compliant permit names a written trigger to stop and get out — any alarm, a change in conditions, loss of ventilation or a break in work — and requires a re-test before re-entry. At completion, sign everyone off, confirm the headcount and cancel the permit.
The Rescue Field Is Load-Bearing
This is the field most often reduced to a tick. The Safe Work Australia model code is explicit that emergency and rescue procedures must be established, equipped and rehearsed before entry, that no permit may be issued where rescue cannot be effected without a rescuer entering, and that non-entry retrieval is the default.
That rules out the two most common plans. “Call 000” is an escalation, not a rescue arrangement. And a tripod, davit and winch over the opening only works on a clean vertical drop: put a bend, an internal baffle, a sloping floor or a side entry between the casualty and the hatch and the retrieval line stops pulling in a useful direction.
When scoping a standby rescue team, STARC starts with the structure, the access and egress route, how a casualty would be packaged and how long it would take to get them to the ground — because that time, not the equipment list, is what the permit is really promising. Where the answer is an entry team, that crew needs breathing apparatus competency and a rescue plan built for the space, and the gap between a written plan and a practised one tends to appear only under load, which is why rescue scenario and rehearsal training exists. It is a non-accredited, customised solution and does not lead to a nationally recognised certificate. If you have an entry booked and no rehearsed rescue arrangement, that is the call to make first, on 1300 178 272.
Who Can Issue, Enter and Gas Test
Nobody holds a licence to issue a confined space entry permit in Australia; the gate is documented competency instead. Issuers, entrants and standby persons each need current, recorded training, and permits and training records must both be kept so an inspector can match the signature to the competency.
STARC’s Enter and Work in a Confined Space course covers MSMPER205 Enter confined space, MSMPER200 Work in accordance with an issued permit, MSMWHS217 Gas test atmospheres and RIIWHS202E Enter and work in confined spaces, each leading to a Statement of Attainment. An issuer who signs off gas readings should hold MSMWHS217, not only the entry units. Where the atmosphere cannot be made safe, MSMWHS216 Operate breathing apparatus is the separate competency, covering use and maintenance of apparatus in an irrespirable atmosphere as defined by AS/NZS 1715:2009.
What STARC Brings to Your Entries
STARC trains and supports crews in construction, manufacturing, oil and gas, mining, utilities and healthcare, across standby rescue for confined space entry, confined space training, and audits and equipment inspections. Training is delivered from the facility at Unit 4/1a Byth St, Stafford QLD 4053, or at your own worksite where your organisation confirms there are suitable facilities on site to run it. Everything is tailored to the space and the task, and quotes are free and obligation-free.
What STARC does not do is issue your permits: that duty stays with the PCBU with management or control of the space. An audit tests your permit system; a standby crew covers the entry itself. Call 1300 178 272 or email info@starc.com.au, Monday to Friday 9:00am to 5:00pm AEST.
Frequently Asked Questions
Does Every Tank Need a Permit?
No — only spaces that meet the regulatory definition of a confined space. Make that call once, through a competent person, write it down, and revisit it when the space’s use or contents change.
Can a Permit Carry Over a Shift Change?
Treat it as finished. A new shift means signing off, re-testing the atmosphere and issuing again, and the same applies after any break in work, personnel change or interruption to ventilation.
Who Issues the Permit on a Contractor Job?
The business with management or control of the space, usually the principal, and hiring a contractor does not transfer it. Duties overlap, so agree in writing who issues, who gas tests and who provides rescue before mobilising.
Signs a Permit Is Not Ready to Sign
Each of these is a defect to close out before anyone signs: isolations listed but not verified, an opening too small to recover a packaged casualty, no second opening to work a casualty towards on a long horizontal run, a gas reading taken only at the lip, a detector with no bump test record, and a standby person also rostered as a worker.
How Long Completed Permits Should Be Kept
Permits must be retained as records, and the retention period is set by your own regulator’s current edition, so work to that. Keep the permit with the gas test and training records.
What a Compliant Entry Needs on Site
At minimum: a calibrated multi-gas detector with a sample pump, mechanical ventilation, verified isolation hardware, harness and retrieval line with an anchor that suits the actual opening, intrinsically safe lighting, a reliable communication method, first aid, and the rescue capability the permit names.
