Confined spaces are one of the highest-risk work environments across multiple industries. Despite the name, a confined space is not simply a tight or restricted space. It’s an enclosed or partially enclosed space that’s not suitable for occupancy.
A confined space poses health and safety risks like dangerous oxygen levels, toxic contaminants, or engulfment. Therefore, it’s a specifically defined hazard zone under Australian Work Health and Safety (WHS) laws, which is why access to any confined spaces require professional training.
Understanding what qualifies as a confined space, and when you need formal training (called a confined space ticket), is essential for worker safety and legal compliance. Here, we delve into everything you need to know about confined spaces and when training becomes mandatory.
What is a Confined Space?
Under the Australian Standard AS2865-Confined Spaces, a confined space is an enclosed or partially enclosed area with the following characteristics:
- Not designed for continuous human occupancy
- Has limited or restricted entry and exit
- May contain harmful levels of oxygen, contaminants, or gases
- Can present serious risks to health and safety
In simple terms, a confined space is not solely defined by a lack of space to navigate in; it’s any area where it’s difficult to enter or exit, and where dangerous atmospheric conditions may exist.
What Qualifies as a Confined Space?
Confined spaces are more common than many people realise. That said, you’ll mostly find them in construction sites, factories, farms, and industrial settings. Even some seemingly simple structures, like pits or trenches, may be classified as confined spaces if potential hazards are present. Typical examples include:
- Storage tanks and silos
- Sewers and drainage pits
- Underground vaults
- Ship ballast tanks
- Boilers and pressure vessels
- Large pipelines
- Manholes and service pits
The Dangers of Working in Confined Spaces
Confined spaces can be hazardous due to limited access and the atmospheric conditions they present. Risks can develop quickly and without warning. Before you know it, you’re trapped. That’s where proper training makes all the difference in how you respond and stay safe.
Confined spaces are dangerous for the following reasons:
- Oxygen deficiency or enrichment: Low oxygen levels can make you pass out in minutes, while high oxygen levels increase fire risk.
- Toxic gases and vapours: Substances like hydrogen sulphide, carbon monoxide, or chemical fumes can be fatal even in small concentrations.
- Engulfment risks: Loose materials such as grain, sand, or liquids can trap or bury workers.
- Limited entry and exit: Rescue operations are often complex and time-critical, as restricted access can delay emergency response and make it harder to safely remove a worker in distress.
- Temperature and physical hazards: Extreme heat, poor ventilation, or moving machinery can increase danger.
What is a Confined Space Ticket?
As per Work Health and Safety (WHS) Regulations, employers must not allow anyone to enter, work in, or oversee a confined space unless they’ve undergone nationally recognised confined space training. The formal certification workers receive is what we call a confined space ticket.
The RIIWHS202E Enter and Work in Confined Spaces qualification typically covers:
- Identifying confined spaces
- Understanding WHS regulations
- Using gas detection equipment
- Following safe entry procedures
- Implementing standby and rescue plans
- Safety precautions in hazardous atmospheres
- Proper use of personal protective equipment (PPE)
Who Needs Confined Space Training?
Generally, you’ll need a confined space ticket if your job involves entering or working in areas classified as confined spaces under WHS regulations. Construction and maintenance workers, plumbers, electricians, industrial cleaners, wastewater and sewer technicians, manufacturing and plant operators, as well as those working in the mining and resource industry need confined space training.
Why Confined Space Training Matters
Confined space training matters because it provides workers with the knowledge and practical skills needed to safely navigate enclosed or partially enclosed structures. While emergencies are unpredictable, proper training significantly reduces the risk of serious injury or fatality.
For employers, ensuring staff are trained in safety and risk management also demonstrates compliance with WHS obligations. Failure to do so can result in regulatory penalties, increased liability, and severe legal consequences should an incident occur.
To reiterate, confined space training matters because it helps workers recognise hazards before entry, use safety equipment correctly, communicate effectively in emergencies, respond to gas alarms or other unsafe conditions, and support safe rescue procedures.
Major Training provides nationally recognised confined space training in Brisbane, the Gold Coast, the Sunshine Coast, Cairns, and across Queensland and NSW.
Frequently Asked Questions (FAQ)
How Long Does a Confined Space Ticket Last in Australia?
A confined space ticket doesn’t technically expire, meaning there’s no set expiry date like that of a forklift licence, for instance. Instead, Australian standards, workplace requirements, and industry expectations are used as a guide. But while the standard (AS2865) doesn’t state a strict expiry period, it requires that workers be competent, and for that competence to remain valid, they must be regularly reassessed to maintain safety. Hence, industry interpretation recommends that a refresher training is taken every 12-24 months. Reassessment may occur even more frequently in certain high-risk industries.
When applying for jobs where a confined space ticket is required, it’s rare for employers to accept certification that’s older than 2-3 years.
What are the Legal Requirements for Confined Space Entry in Australia?
Confined space work is regulated under WHS laws and supported by AS2865. Before entry, employers must ensure that:
- A confined space entry permit is issued
- Atmosphere testing is conducted
- A standby safety personnel is present
- Emergency and rescue procedures are in place
- A confined space risk assessment is completed
- And of course, that workers hold a confined space ticket
What is the Difference Between Confined Space and Working at Heights?
Confined spaces involve hazardous atmospheres and restricted entry, while working at heights involves fall risks. Both pose different risks, which is why safety training and controls are separate.
Can a Confined Space Become Safe Once Ventilated?
Ventilation can reduce risk, yes, but atmospheric testing and continuous monitoring are still required. Since conditions can change quickly, safety procedures must always be followed.
Is a Spotter Required for Confined Space Entry?
Yes. A standby person, often called a “spotter”, must be assigned for any entry into a confined space.
The designated personnel must be trained and competent. They shouldn’t be assigned other duties that could distract them. They must not enter the confined space themselves unless they’re part of a professionally trained rescue team armed with the necessary equipment.
