Confined spaces kill and injure workers in Australia every year, often because someone climbed into a tank, pit or trench without the right training. A confined space is a place not designed for people to occupy that has restricted entry or exit and can have a dangerous atmosphere — think tanks, silos, sewers, pits, ducts, boilers, pipes and some trenches. The air inside can be short of oxygen, full of toxic gas, or flammable, and it can turn deadly in seconds without warning.
A confined space entry ticket is the training that proves you understand those risks and know how to enter safely under a permit system. It's an advanced credential compared with a White Card, and it's genuinely serious — this is one area where cutting corners can cost lives. This guide covers what the ticket involves, what it costs, where to get it and when you actually need it on site.
What counts as a confined space
Under the model WHS Regulations, a confined space has a specific legal definition. It's an enclosed or partially enclosed space that:
- Is not designed or intended primarily to be occupied by a person
- Is designed at normal atmospheric pressure while anyone is inside
- Has a risk to health and safety from harmful airborne contaminants, unsafe oxygen levels, or engulfment
A space being small and awkward doesn't automatically make it a confined space in the legal sense — and a large space can still be one if the atmosphere is the hazard. The classic dangers are:
- Lack of oxygen — displaced by other gases, or used up by rust or rotting material
- Toxic gases — like hydrogen sulphide in sewers or carbon monoxide from engines
- Flammable atmospheres — vapours that can ignite or explode
- Engulfment — being buried by grain, sand, liquid or sludge
What the ticket covers
The common nationally recognised units are RIIWHS202E Enter and work in confined spaces and, for those who supervise, additional units around gas testing and issuing entry permits. A typical course teaches you to:
- Identify confined spaces and the hazards inside them
- Interpret and follow a confined space entry permit
- Use atmospheric gas testing equipment
- Set up and use ventilation
- Select and wear the right PPE, including respiratory protection and harnesses
- Understand the roles of the entrant, the standby person and the permit issuer
- Follow emergency and rescue procedures
Confined space work is never a solo job. There's always a permit, a standby person outside, communication arrangements and a rescue plan. If any of that isn't in place, you don't go in.
When you actually need it on site
You need confined space training whenever your work requires you to enter a confined space. That's most common in trades like plumbing, civil construction, water and sewer, refrigeration and air conditioning, boilermaking and welding, and industrial maintenance.
Under WHS law, a business must not direct or allow a worker to enter a confined space unless they hold the right training and a valid entry permit is in place. So even if you're keen and capable, an employer legally cannot send you into a confined space without it. As an apprentice, you should never be pressured to enter one without the ticket, a permit and proper supervision — if that happens, it's worth reading your rights as an apprentice and talking to your boss about problems.
What it costs and how long it takes
Prices vary by state and RTO, so treat any figure as approximate. Confined space entry is a specialised course, so it usually costs more than a White Card or awareness course, and it often runs over one to two days including practical assessment. Combined courses that bundle confined space entry with gas testing or working at heights are common and can be better value if you need both.
Because the training expires and needs refreshing (many employers and sites expect it kept current, often on a rolling basis of a few years), factor in that you'll redo it periodically. Many employers and Group Training Organisations will pay for this ticket because they can't legally use you on confined space jobs without it — so ask before you fork out yourself.
How it fits with your other tickets
Confined space work rarely happens in isolation. You'll often need it alongside:
- A White Card for general construction site access
- A working at heights ticket where entry involves ladders, harnesses or elevated access
- Gas testing (test and monitor atmospheres) if you'll be doing the testing yourself
- First aid, since standby and rescue roles often expect it — see first aid and CPR certificates
If you're mapping out which credentials to invest in first, our guide on which tickets actually get you hired puts confined space in context — it's high value but usually only worth doing once your trade actually needs it.
Safety mindset matters more than the certificate
Holding the ticket is the legal starting point, not the finish line. The apprentices who last in confined space environments are the ones who treat every entry with respect: they check the permit, confirm the gas readings, keep the standby person in constant contact, and never assume "it was fine last time." Atmospheres change. A space that was safe yesterday can be lethal today.
If anything feels wrong — a smell, a reading, a broken procedure, a missing standby person — stop and speak up. No job is worth your life, and no decent employer will hold it against you for refusing an unsafe entry. That kind of judgement is exactly what employers notice and remember.

Key takeaways
- A confined space has restricted entry/exit and a potential atmospheric or engulfment hazard — tanks, pits, sewers, silos and more.
- The main ticket is RIIWHS202E Enter and work in confined spaces; supervisors may also need gas testing units.
- WHS law bans anyone entering a confined space without training and a valid entry permit.
- Never enter a confined space as an apprentice without the ticket, a permit, a standby person and a rescue plan.
- It's a specialised, more expensive course, often over one to two days, and needs periodic refreshing.
- Many employers and GTOs pay for it — ask before paying yourself.
