What Rescue Equipment Is Required for Confined Space Entry in WA?
Updated: Aug 19
Confined spaces have a way of making even experienced workers stop and think twice. Whether you're dealing with a storage tank, underground vault, or enclosed machinery space, the risks are real, and the regulations around them are serious. If you're working in Western Australia, understanding confined space rescue equipment requirements isn't just good practice; it's a legal obligation that could save lives, including your own.
But here's the thing: knowing what equipment you need doesn't have to feel like wading through a legal textbook. This post breaks it all down into a clear, easy-to-follow list so you can get the information you need without the headache.
What Makes a Space 'Confined' Under WA Law
Let's clear up one of the most misunderstood areas of worksite safety in WA, because getting this wrong has real consequences.
Under the Work Health and Safety (General) Regulations 2022 (WA), a confined space is defined as an enclosed or partially enclosed space that is not designed or intended for ongoing human occupancy, operates at normal atmospheric pressure during occupancy, and presents a risk to health and safety. Here's the part that trips most workplaces up: the definition is entirely about the hazards present, not the physical size or shape of the space. A large open-top processing vessel on a Pilbara mine site can absolutely be a confined space. A small crawlspace may not be. Square footage is irrelevant. Hazards are everything.
When Do Your Legal Obligations Actually Kick In?
This is where a lot of WA workplaces get caught out. Legal obligations are triggered the moment a person's head or upper body crosses the boundary of the space, not when they are fully inside. A worker leaning into a pit to check a gauge, retrieve a tool, or visually inspect a reading has technically entered a confined space under WA law. At that point, the full suite of obligations applies: atmospheric testing, a trained standby person stationed outside, emergency rescue planning, and a valid entry permit where required.
What Makes It a Permit-Required Confined Space?
A confined space becomes a Permit-Required Confined Space (PRCS) when it contains one or more of the following:
A hazardous atmosphere (low oxygen, toxic gas, or flammable vapour)
An engulfment risk from materials like slurry, grain, or water
Inwardly converging walls or a floor that slopes to a smaller cross-section
Any other recognised serious hazard, including unguarded machinery or extreme heat
Misidentifying a confined space is one of the most common compliance failures observed by WorkSafe WA. When the classification step is skipped or done incorrectly, the entire chain of rescue readiness breaks down. No correct classification means no correct equipment selection, and that's where people die. Between 2000 and 2012, Australia recorded 59 confined space accidents, with atmospheric hazards causing up to 82% of fatalities.
WA Industry Examples Worth Knowing
Confined spaces show up right across WA's industrial landscape. Common examples include:
Storage and processing tanks on mining, agricultural, and oil and gas sites
Underground pits, vaults, and sewers in utilities and telecommunications
Ship holds at Naval Base, a working environment that demands site-specific rescue planning
Mine stopes and shafts across WA's resources sector
Processing vessels in oil and gas operations where residual hydrocarbons or H₂S may be present
All of these environments fall under the WHS General Regulations, with mine sites additionally covered by the Work Health and Safety (Mines) Regulations 2022. Correct identification is the foundation that every rescue equipment decision is built on.
Why Rescue Equipment Must Be Ready Before Entry, Not After
Here's something that catches a lot of people off guard: the law doesn't allow you to go and fetch rescue equipment once something goes wrong inside a confined space. Under AS 2865-2009 (Confined Spaces), the primary technical standard governing confined space work across Australia, rescue equipment must be staged and ready at the entry point before anyone sets foot inside. This standard is embedded directly into WA's regulatory framework under the Work Health and Safety (General) Regulations 2022, meaning it carries full legal weight for every PCBU operating in Western Australia.
The SafeWork Australia Model Code of Practice for Confined Spaces, updated in November 2024, reinforces this as a non-negotiable. Section 5 of the Code makes it clear that emergency response planning, including the physical placement of rescue equipment, must be completed before entry commences. This is the national guidance document that both PCBUs and registered training organisations are expected to reference when designing safe work procedures or delivering training. If your procedures were last reviewed before November 2024, they're already out of date.
The unit of competency RIIWHS202E (Enter and Work in Confined Spaces) ties this directly to worker obligations. Rescue equipment must be positioned at the entry point, confirmed as serviceable, and immediately accessible to the standby person stationed outside. There is no provision for improvised retrieval mid-emergency. The standby person's entire role depends on having the right gear on hand from the moment entry begins.
Now here's the statistic that should make every supervisor stop and think. Approximately 25% of confined space deaths in Australia involve would-be rescuers who entered the space without proper training or equipment, and were overcome by the same hazard that trapped the original worker. That figure reframes the entire conversation around rescue readiness.
The financial and legal stakes are just as serious. Australian court prosecutions related to confined space entry failures have reached $600,000 or more in penalties under WHS legislation. That's the cost of not having equipment ready, a plan in place, and a competent standby person at the entry point. It's a preventable outcome every time.
At Safety Heights and Rescue Training, our confined space training covers exactly these obligations, so your team understands what "ready before entry" actually looks like in practice.
The Required Rescue Equipment: A WA-Specific Breakdown
Before we get into the list, it's worth being upfront about something: there is no single universal equipment checklist that applies to every confined space entry in WA. Under AS 2865-2009 and the WA WHS (General) Regulations 2022, the rescue equipment you need at the entry point is directly tied to your hazard identification and risk assessment for that specific space. Equipment selection must also align with the emergency rescue procedure documented in your entry permit. That said, there are core categories that consistently appear across compliant operations, and these are the ones you need to understand.
Here are the core rescue equipment categories required at the entry point:
Atmospheric monitoring equipment — A calibrated gas detector must be used to test the atmosphere before entry and monitored continuously during work. Given that atmospheric hazards account for up to 82% of confined space fatalities in Australia, this is non-negotiable.
Retrieval and extraction systems — Full-body harnesses, lifelines, and mechanical retrieval devices such as tripods or davit arms allow for non-entry rescue where practicable. Non-entry rescue is the preferred method under AS 2865-2009.
Respiratory protective equipment — SCBA or supplied-air breathing apparatus is required where atmospheric hazards are identified in the risk assessment.
Emergency communication equipment — The standby person must maintain continuous contact with entrants throughout the operation.
First aid equipment — Appropriate to the specific hazards identified, documented in the entry permit.
Tripod or Davit Arm
A tripod or davit arm is your anchor system, positioned directly over the confined space entry point to allow vertical retrieval of a worker without anyone needing to go in after them. This is a big deal. Rather than sending a rescuer into the same hazardous atmosphere that incapacitated the original entrant, a retrieval line attached to the worker's harness runs up through the anchor and connects to a mechanical winch or self-retracting lanyard (SRL). When something goes wrong, the standby person can haul the worker straight out from above. No entry required.
This approach, known as non-entry rescue, is the preferred method under AS 2865-2009 and the SafeWork Australia Model Code of Practice for Confined Spaces. The standard is clear: where non-entry retrieval is practicable, it should be used. Given that approximately 25% of confined space deaths in Australia involve would-be rescuers, keeping people outside the space wherever possible is not just preferred, it is the safer call every time.
In WA industries, you will typically see two main configurations. Portable aluminium tripods are the go-to for manholes, stormwater pits, and general civil access points, offering quick setup and easy transport between sites. Fixed davit arms are more common on process vessels, storage tanks, and industrial plant equipment, particularly across WA's resources and manufacturing sectors, where a permanent overhead anchor makes more practical sense.
Regardless of configuration, all anchor equipment used as part of a confined space rescue system must comply with the AS/NZS 1891 series (Industrial Fall-Arrest Systems and Devices). This covers load ratings, certification, and compatibility with harnesses and retrieval lines. Any anchor point must be rated and inspected to standard before every entry, with faults reported and rectified before work begins.
Retrieval Winch and Rescue Line
The retrieval winch works alongside your anchor system to give the standby person the mechanical advantage needed to pull an incapacitated worker vertically out of the space, all without stepping inside themselves. That matters enormously, because approximately 25% of confined space deaths in Australia involve would-be rescuers who entered unprepared. A correctly set up winch keeps the rescue happening from the outside, where it's safe.
When selecting a winch, you need to confirm three things upfront. First, the rated capacity must be appropriate for human loads, not just equipment. A standard rigging winch is not a substitute. Second, the line length needs to exceed the depth of the space with enough extra to account for the rigging configuration. If your space is eight metres deep, a six-metre line will fail you at the worst possible moment. Third, look for anti-panic and automatic locking features, which prevent uncontrolled descent if the operator loses grip during a retrieval.
Under RIIWHS202E (Enter and Work in Confined Spaces), the rescue line must be attached to the worker's harness before entry begins, not after they've gone in. This is a non-negotiable step in the pre-entry process and should be confirmed by the standby person as part of their checklist.
For manual winches, these are generally suitable for shallower spaces with straightforward vertical access. Once depth increases or the entry path becomes offset or complex, a mechanical winch is the more appropriate choice, reducing physical load on the standby person and improving retrieval speed when seconds count.
Full-Body Harness
When it comes to confined space retrieval, not just any harness will do. Under AS/NZS 1891.1, the required body-wear for confined space entry is a full-body harness, full stop. Waist belts and chest harnesses are not acceptable substitutes, and this is not a grey area. The reason comes down to basic physics and what actually happens when you need to pull someone out who can't help themselves.
A full-body harness distributes retrieval forces across the shoulders, chest, and legs simultaneously. If you used a waist belt on an unconscious worker and hauled them vertically through a narrow entry point, the belt would fold them at the midsection, creating a serious obstruction and significantly increasing the risk of internal injury or suspension trauma. A full-body harness keeps the worker upright and aligned, which is exactly the position needed for a smooth vertical extraction through a confined space opening.
Fit and sizing matter just as much as the harness type itself. A poorly fitted harness can shift during a retrieval, creating injury risk or making extraction more difficult. Harnesses must be adjusted to fit the individual worker, and the retrieval line should be attached to the dorsal D-ring before the worker crosses the entry boundary. This is a procedural requirement, not a suggestion. The harness goes on outside the space, the retrieval line connects, and then entry begins.
Before any of that happens, the harness needs to pass a pre-use inspection. This means checking the webbing for cuts, abrasion, UV degradation, or chemical exposure; checking buckles and D-rings for deformation or corrosion; and verifying that stitching at load-bearing points is intact. If anything looks off, the harness comes out of service immediately. This inspection is a before-each-use requirement as part of your pre-entry equipment serviceability check, not just an annual tag-and-test event.
For further guidance on confined space entry planning, WorkSafe NZ's confined space resource provides a solid reference, though always apply the WA WHS (General) Regulations 2022 as your primary compliance framework.
Atmospheric Monitoring Equipment
Here's a number that should stop you in your tracks: between 2000 and 2012, atmospheric hazards were responsible for up to 82% of confined space fatalities in Australia, across 59 recorded accidents. That's not a minor risk factor you can manage with a quick sniff test at the entry point. It's the single biggest killer in confined space work, and it's exactly why atmospheric monitoring is legally and practically non-negotiable on every WA worksite.
Under AS 2865-2009 and the WA Work Health and Safety (General) Regulations 2022, there are four key atmospheric parameters that must be tested before entry and monitored throughout the work:
Oxygen (O₂) level - tested first, every time. The safe range is 19.5% to 23.5% by volume. Below that and workers can lose consciousness in minutes; above it and you've got a serious fire and explosion hazard.
Flammable gas and vapour concentration - measured as a percentage of the Lower Explosive Limit (LEL). General entry requires readings below 10% LEL; hot work requires below 5% LEL.
Toxic gas concentration - measured against Workplace Exposure Standards, covering common culprits like carbon monoxide (CO) and hydrogen sulphide (H₂S).
Any other hazards identified in the risk assessment - site-specific contaminants like ammonia or chlorine may also need to be monitored depending on what your risk assessment turns up.
Testing isn't a one-time tick-box activity either. Regulation 71 of the WA WHS Regulations requires testing to be conducted "as often as necessary," which in practice means continuous monitoring during entry for permit-required confined spaces. Conditions can change rapidly, particularly when sludge or sediment is disturbed during work.
Gas testing must be carried out by a competent person. The relevant nationally recognised training unit is MSMWHS217 – Gas Test Atmospheres, which covers the skills and knowledge needed to safely test atmospheric conditions using calibrated detection equipment. If your team is doing confined space work, this training isn't optional.
On alarm thresholds: modern multi-gas detectors are set with warning and alarm levels for each parameter. If readings shift during the job and alarms activate, the obligation is clear - evacuate immediately and reassess before anyone re-enters. Monitoring doesn't stop when the permit is signed; it runs for the full duration of the work. For further reading on current national guidance, the SafeWork Australia Model Code of Practice for Confined Spaces is a solid reference point alongside your WA-specific obligations.
Supplied-Air Breathing Apparatus (SABA) or Appropriate Respiratory Protection
Not all respiratory protection is created equal, and this distinction genuinely matters when you're planning confined space rescue equipment in WA.
Air-purifying respirators (APRs) work by filtering contaminants from the surrounding air using cartridges or canisters. They're useful in some low-risk environments, but they have a critical limitation: they cannot supply oxygen. If the atmosphere inside a confined space is oxygen-deficient (below 19.5% O₂) or classified as immediately dangerous to life or health (IDLH), an APR is completely useless and potentially fatal to the person wearing it. Under AS 2865-2009, these atmospheric conditions require supplied-air breathing apparatus (SABA), which delivers clean, breathable air from an independent source via an airline hose connected to an external compressor or cylinder bank.
Here's the part that often gets overlooked: even when atmospheric testing confirms that workers inside the space are operating in a safe atmosphere, SABA must still be staged and ready at the entry point for use by a trained rescuer. Conditions inside a confined space can deteriorate rapidly and without warning. A rescuer entering during an emergency may encounter a very different atmosphere to what was tested at the start of the shift. Having SABA available at the entry point is a rescue readiness requirement, not an optional extra.
SABA is not a grab-and-go piece of kit. Anyone expected to use it in a rescue scenario must be formally trained in its operation, including donning, adjustment, emergency procedures, and equipment limitations. The Breathing Apparatus course delivered by Safety Heights and Rescue Training is the appropriate nationally recognised training pathway for this requirement, equipping workers and standby personnel with the practical competency to operate breathing apparatus safely under pressure.
Self-contained breathing apparatus (SCBA) is sometimes used as an alternative for certain rescue scenarios, particularly where hose tethering via SABA is impractical due to space geometry or rescue route complexity. SCBA carries its air supply with the user, which offers greater mobility. However, it comes with real limitations. Standard SCBA cylinders typically provide between 30 and 60 minutes of air supply, and that duration drops significantly under the physical demands of an active rescue. Cylinder management and equipment donning also require specific training. For guidance on when to use SCBA versus supplied-air respirators, the nature, duration, and location of the atmospheric hazard are all deciding factors.
The bottom line: respiratory protection selection for confined space rescue in WA must be based on the actual and potential conditions a rescuer may face, and the equipment must be ready, serviceable, and operated by someone who genuinely knows how to use it.
Communication Device
Keeping the lines open between the worker inside and the standby person at the entry point isn't optional; it's a legal requirement under Australian WHS legislation and a core competency element of RIIWHS202E (Enter and Work in Confined Spaces). The standby person is obligated to maintain contact at all times throughout the entry, not just at the start and finish. Loss of communication can be the first sign that something has gone seriously wrong, so the moment contact drops, emergency procedures should be activated immediately.
The right communication method depends on the space itself. For short, shallow spaces where the entrant and standby person are within natural speaking range, direct verbal communication may be sufficient. For deeper or more complex entries, intrinsically safe two-way radios are the practical standard, providing reliable two-way contact without requiring the standby person to lean into the space. Hardwired communication systems are another solid option, particularly in environments where metal structures or underground geometry can degrade radio frequency signals. As a backup when electronics fail or aren't practical, tug-line signals using pre-agreed sequences before entry can convey basic status information and emergency alerts.
One point that catches people off guard: if the space has any risk of explosive or flammable gas, your communication device must be intrinsically safe and rated for the specific hazardous area classification applicable to that space under Australian standards. A standard consumer radio or mobile phone can generate enough heat or spark to ignite a flammable atmosphere. This is non-negotiable under AS 2865-2009 and the broader confined space entry framework that governs WA workplaces. Always confirm the hazardous area zone classification before selecting your device, and ensure it's been tested as serviceable before entry begins.
First Aid Kit and Emergency Oxygen
First aid at the entry point isn't an afterthought; it's a legal requirement. Under the WA WHS (General) Regulations 2022, first aid facilities must be accessible at the confined space entry point specifically, not just somewhere in the broader workplace. This is a location-specific obligation, and it matters because response time in a confined space emergency can be the difference between a rescue and a fatality.
One thing that often gets overlooked is that a standard workplace first aid kit won't cut it here. The kit at your entry point needs to reflect the hazards identified in your confined space risk assessment. If your risk assessment flags chemical exposure, burns risk, or eye irritation hazards, your kit needs to address those directly. The WA Country Health Service Confined Space Procedure reinforces this, confirming that equipment must be selected based on the hazard assessment and the task being performed.
Emergency oxygen, sometimes called resuscitation oxygen, is a critical piece of that hazard-specific provision. Where atmospheric hazards such as oxygen deficiency or toxic gas exposure like carbon monoxide or hydrogen sulphide are identified, a collapsed worker may have critically depleted blood oxygen levels. Standard CPR alone won't address that. Having resuscitation oxygen at the entry point allows the standby person to begin oxygenation immediately while waiting for emergency services to arrive.
The applicable guidance document for first aid requirements in WA is the Code of Practice: First Aid in the Workplace, approved under section 274 of the WHS Act 2020. Following this code isn't optional best practice; it carries legal weight in WA court proceedings.
The Standby Person vs. a Rescue Team: What's the Difference?
Now that we've covered what equipment needs to be at the entry point, it's worth talking about the people responsible for using it, because there's a meaningful difference between a standby person and a trained rescue team, and confusing the two can cost lives.
What a Standby Person Actually Does
Under AS 2865-2009 and the WA Work Health and Safety (General) Regulations 2022, the standby person is a dedicated, competent individual stationed at the confined space entry point for the entire duration of the entry. Competent here means they genuinely hold the knowledge and skills to perform the role, not just that they happened to be nearby. Critically, the standby person must not enter the confined space themselves. The moment they step in, the entrant loses their outside support, and the entire safety framework collapses.
Their responsibilities during an entry are clearly defined and non-negotiable:
Controlling and maintaining the entry permit throughout the operation
Operating the retrieval winch and anchor system for non-entry rescue if required
Monitoring continuous atmospheric readings from outside the space
Maintaining two-way communication with the entrant at all times
Summoning emergency services and initiating the rescue plan the moment something goes wrong
This is non-entry rescue, and it is the legally preferred method under Australian confined space requirements. The standby person uses the retrieval system to extract an incapacitated worker from outside the space, without anyone else going in.
When a Trained Rescue Team Is Required
Here's where the distinction gets critical. A standby person performing non-entry retrieval and a trained confined space rescue team performing entry rescue are two very different competency levels, with different training pathways and very different risk profiles.
Under AS 2865-2009, where non-entry rescue is not practicable, a trained rescue team must be available. Under WA law, "available" does not mean you can call 000 and hope for the best. It means ready to respond within a timeframe that genuinely prevents serious injury or death, accounting for the specific space and its hazards.
This matters enormously when you look at the numbers. Approximately 25% of confined space fatalities involve would-be rescuers, most of them untrained bystanders who entered without atmospheric clearance or proper equipment. They saw someone in trouble and acted on instinct, and it killed them. Formalised rescue team training exists precisely to prevent that outcome, giving responders the skills to assess the atmosphere, don appropriate respiratory protection, and execute a safe entry rescue rather than becoming the next victim.
Equipment Inspection and Serviceability: What the Regs Actually Require
Under RIIWHS202E (Enter and Work in Confined Spaces), the serviceability requirement isn't a suggestion buried in the fine print. Performance Criterion 1.8 requires workers to check all tools and equipment for serviceability and rectify or report any faults before entry commences. Criterion 1.9 goes further, requiring rescue equipment to be physically positioned at the entry point before anyone crosses the threshold. The combined effect is straightforward: if your equipment has a fault, you fix it, escalate it, or you don't enter. There is no middle ground.
Pre-Entry Checks by Equipment Category
Every piece of rescue equipment at the entry point needs a deliberate pre-entry inspection, not just a glance. Here's what that looks like across each category:
Harness webbing and stitching: Check for cuts, abrasion, chemical contamination, heat damage, and whether any load-indicator stitching bridges have deployed.
Winch line and braking mechanism: Inspect wire rope or kernmantle for kinks, broken strands, and corrosion. Test brake engagement and release under controlled conditions.
Tripod leg locks and anchor integrity: Confirm locking pins fully engage, feet are stable and non-slip, and the anchor head is rated and undamaged.
Gas monitor calibration and bump test: A bump test (functional response check) is required before each use. Full calibration is a separate obligation performed at manufacturer-specified intervals, typically every six months.
SABA cylinder pressure and regulator function: Cylinder pressure must be sufficient for the planned entry duration. Confirm regulator function, demand-valve response, and low-pressure alarm are all serviceable.
Communication device battery and transmission: Battery charge and two-way transmission must be confirmed with the standby person before entry begins.
Record-Keeping and Ongoing Inspection Obligations
Inspection outcomes aren't just verbal tick-offs. Under the WA WHS (General) Regulations 2022, a confined space entry permit is a mandatory document, and equipment serviceability status, gas monitor bump test results, and cylinder pressures should all be recorded as part of that permit. Retain those records in line with your WHS record-keeping obligations under the current Regulations.
Beyond pre-entry checks, periodic inspection obligations also apply. Manufacturer-recommended service intervals for winches, fall-arrest blocks, and SABA equipment are a legal baseline, not optional guidance. Any equipment involved in a rescue, shock-load event, or near-miss must be withdrawn from service and inspected before reuse, regardless of where it sits in the scheduled service cycle. For harnesses and fall-arrest equipment specifically, AS/NZS 1891.4 requires annual inspection by a competent person, typically a qualified third-party inspector, with higher-frequency checks in intensive-use environments.
One final point worth being direct about: if a pre-entry inspection identifies a fault, that equipment must be tagged out of service and physically removed from the entry point. Leaving defective gear nearby as a contingency creates a documented risk that it will be grabbed under pressure during a real rescue scenario. RIIWHS202E does not contemplate a "leave it and see" approach, and neither does WorkSafe WA.
The Rescuer Fatality Problem: Why Equipment Alone Is Not Enough
Here's a number that should fundamentally change the way you think about confined space rescue equipment: approximately 25% of confined space deaths in Australia involve would-be rescuers. Not the original casualty. The person who saw a colleague in distress and went in to help. That figure comes from Australia's own documented incident record, covering 59 confined space accidents between 2000 and 2012, and it reflects a pattern of behaviour that training and legislation have been specifically designed to interrupt.
The Instinct to Help Can Be Fatal
The mechanism behind rescuer deaths is straightforward and tragic. An untrained bystander sees someone collapse inside a confined space, reacts on instinct, and enters the same atmosphere without atmospheric testing, without breathing apparatus, and without a retrieval line. Within seconds, the same invisible hazard that incapacitated the first worker takes down the second. The legal framework under the WA Work Health and Safety (General) Regulations 2022 and AS 2865-2009 exists precisely to break this cycle. Requiring pre-positioned rescue equipment, a trained standby person, and a documented emergency response plan before entry begins is not bureaucratic box-ticking; it is a direct countermeasure to the most common cause of rescuer fatalities.
The Atmospheric Hazard Reality
Between 2000 and 2012, atmospheric hazards were responsible for up to 82% of confined space fatalities in Australia. Oxygen deficiency, carbon monoxide, hydrogen sulphide, methane; these hazards are fast-acting, often invisible, and completely odourless in the case of CO. An incapacitated worker lying in an oxygen-deficient space cannot be safely retrieved by someone who just rushed in without supplied-air breathing apparatus and the training to use it under pressure. Equipment alone, sitting at the entry point, solves nothing if the person operating it does not know how to deploy it correctly in a live emergency.
This Risk Has Not Gone Away
If the 2000 to 2012 data feels dated, consider this: atmospheric hazards in restricted zones still account for nearly 15% of industrial fatalities annually in Australia, based on 2026 compliance data. Under the WA WHS (General) Regulations 2022 and AS 2865-2009, having the right rescue equipment at the entry point, operated by a trained standby person or rescue team, is the minimum legal standard, not an optional upgrade. The combination of correct equipment and competent personnel is what the law requires, and what actually saves lives.
Which Training Units Cover Which Equipment?
One of the most common misconceptions we see is workers assuming that holding RIIWHS202E (Enter and Work in Confined Spaces) ticks every box for confined space compliance. It doesn't, and understanding why matters a lot for supervisors building compliant entry teams in WA.
RIIWHS202E: Entry, Retrieval, and Standby Coordination
RIIWHS202E covers the equipment competencies most people associate with confined space entry. Under the unit's performance criteria, workers must select and wear appropriate PPE (including full-body harnesses), position retrieval systems at the entry point before entry begins, and check all equipment for serviceability before use. Faults must be rectified or reported; you cannot simply proceed and hope for the best. The unit also embeds communication and standby person coordination directly into its assessment requirements. Workers must obtain and interpret emergency procedures with the standby person before entry, and maintain ongoing communication throughout the task.
Gas Testing Units: Atmospheric Monitoring from Instrument to Record
The gas testing unit sits alongside RIIWHS202E, not inside it. While RIIWHS202E requires workers to monitor the atmosphere during an entry, the dedicated gas testing unit covers the full competency chain: selecting the right instrument for the specific hazard, performing calibration and bump testing (two distinct procedures), interpreting readings against alarm thresholds, and maintaining formal atmospheric test records. In extractive industries, the relevant unit is RIIWHS205E. For workers in manufacturing or general industry, MSMWHS217 (Gas Test Atmospheres) is typically the applicable unit. The difference comes down to your industry classification, and getting that wrong is a surprisingly common compliance issue across WA's mixed-industry workforce.
Breathing Apparatus: A Standalone Competency
The Breathing Apparatus unit covers competencies that neither of the above units address. Workers learn to correctly don and doff both SCBA and SABA equipment, manage air supply including cylinder duration and low-pressure alarm response, communicate effectively while wearing a facepiece, and execute emergency procedures including emergency escape from a confined space while wearing BA.
How the Units Work Together
A compliant entry team in WA typically spans all three units. Entrants need RIIWHS202E at minimum; those conducting atmospheric testing need the relevant gas testing unit; those entering atmospheres that are or may become immediately dangerous to life need the BA unit as well. Supervisors carry explicit obligations under the WA WHS (General) Regulations 2022 to verify that every team member holds current, relevant competencies before authorising entry, not just to assume they do.
Safety Heights delivers all of these nationally recognised units from its Naval Base, Perth facility, and offers course combinations specifically suited to WA industry workers and supervisors working across the Kwinana, Henderson, and Rockingham industrial corridors.
WA-Specific Considerations for Confined Space Rescue Equipment
If you're based in Perth or anywhere else in WA, it's worth being clear about who's in charge of your confined space compliance. WorkSafe WA, operating under the Department of Mines, Industry Regulation and Safety, is the relevant regulatory authority for all WA workplaces. WA operates under the Work Health and Safety Act 2020 and the Work Health and Safety (General) Regulations 2022, which is a separate and distinct legislative instrument from what applies in other states. NSW, for example, commenced its revised Work Health and Safety Regulation 2025 in August 2025, and Queensland operates under its 2011 Regulation. These are not interchangeable frameworks, so referencing interstate guidance as if it applies here is a compliance risk in itself.
In WA, confined space rescue equipment requirements come up most frequently across a handful of industries. Resources and mining sit at the top of the list, given the scale of WA's sector and the prevalence of mine stopes, shafts, and tanks. Oil and gas processing, utilities (water, wastewater, and power infrastructure), and maritime and shipbuilding around Naval Base and Fremantle also generate significant confined space activity. Construction sites round out the picture, particularly where underground services or site infrastructure are involved.
What's shifting in 2025 and 2026 is the level of scrutiny WorkSafe WA inspectors are applying to rescue team readiness and standby person competency. For PCBUs, this means training currency records, competency verification, and rescue planning documentation need to be in good order before an inspector shows up, not scrambled together afterwards. The WA Code of Practice is an approved code under section 274 of the WHS Act 2020, meaning courts can rely on it when assessing what was "reasonably practicable." That's a significant compliance lever.
On the admin side, the industry shift toward digital confined space permit programs is worth taking seriously. Paper-based systems are increasingly seen as a liability in WA workplaces, with digital platforms now expected to generate auditable atmospheric test records and demonstrate due diligence during WorkSafe WA compliance audits.
Finally, the SafeWork Australia Model Code of Practice for Confined Spaces was updated in November 2024 and sets the national baseline. WA PCBUs should check directly with WorkSafe WA to confirm how that updated code interacts with WA's current approved code and 2022 regulatory framework.
Frequently Asked Questions
Is a tripod mandatory for every confined space entry in WA?
No, a tripod is not automatically required for every entry. What is required is a non-entry retrieval system wherever vertical retrieval is practicable. The specific equipment depends on your risk assessment and the configuration of the space. A tripod is a common solution for vertical entries, but a davit arm or similar anchor system may be equally appropriate depending on the setup. The key obligation under AS 2865-2009 and the WA WHS (General) Regulations 2022 is that a non-entry rescue method must be in place before anyone steps inside.
Can the same person be both the entrant and the standby person?
Absolutely not. The standby person must be fully dedicated to monitoring and rescue throughout the entire entry. They cannot enter the space, and they cannot take on any other task that pulls their attention away from the entrant. This is a clear requirement under AS 2865-2009 and the WA WHS Regulations, and misidentifying or doubling up roles is one of the most common compliance failures WorkSafe WA inspectors flag during site visits.
How often does confined space rescue equipment need to be inspected?
Pre-entry inspection is required before every single entry, no exceptions. Beyond that, periodic inspection timelines are set by manufacturer guidelines and the relevant Australian Standards. For fall-arrest and retrieval equipment specifically, AS/NZS 1891.4 requires annual third-party inspection. Keep your inspection records current and accessible.
Does a worker need separate training for each piece of rescue equipment?
Yes. RIIWHS202E covers harness use and retrieval systems, but breathing apparatus and gas monitoring equipment each require their own separate nationally recognised training units. All competencies must remain current.
What are the penalties for non-compliance in WA?
They are significant. Australian court prosecutions related to confined space failures have reached $600,000 or more. WorkSafe WA can issue improvement notices, prohibition notices, and pursue prosecution under the WHS Act 2020. Non-compliance is not a minor administrative issue; it carries serious legal and financial consequences.
Getting Your Rescue Equipment Right: Key Takeaways
Here's the bottom line on confined space rescue equipment requirements in WA: under the WA WHS (General) Regulations 2022 and AS 2865-2009, your rescue equipment must be physically present at the entry point, confirmed serviceable, and ready to operate before a single worker crosses the confined space boundary. Not nearby. Not in the ute. At the entry point, checked, and ready to go.
Having the right gear on site is only half the equation. As we've covered throughout this article, approximately 25% of confined space deaths in Australia involve would-be rescuers. Equipment without trained hands behind it isn't a rescue plan; it's a false sense of security. The distinction between a standby person and a full rescue team matters enormously, and regulators are paying closer attention to standby-person competency now more than ever.
A practical next step: use the equipment list in this article to audit your current confined space setup, then verify that every team member holds current, nationally recognised competencies across the relevant units.
For teams looking to upskill in confined space entry, gas testing, breathing apparatus, or rescue procedures, Safety Heights and Rescue Training delivers nationally recognised training from Naval Base, Perth, with course combinations built specifically for WA industry workers and supervisors.
Conclusion
Confined space safety in Western Australia is not something to improvise. Having the right rescue equipment on-site before entry begins is a legal requirement, a moral responsibility, and your best line of defense when things go wrong.
To recap the key takeaways: rescue equipment must be selected based on the specific hazards of each space; atmospheric monitoring, retrieval systems, and emergency breathing apparatus are non-negotiables; and every piece of gear is only as effective as the trained team behind it.
Regulations exist for a reason, and staying compliant protects everyone on your crew.
Ready to make sure your confined space rescue setup meets WA requirements? Review your current equipment list, consult your safety officer, and consider booking a refresher training session. The right preparation today could be the difference that brings your whole team home safely tomorrow.
