Quick answer
A confined space entry permit is a formal, written authority to enter a confined space. It records the specific space, the hazards, the controls in place, atmospheric test results, who’s authorised, and the time the entry is valid for. No permit, no entry — it’s the control that makes sure every risk has been checked before anyone goes in.
What a permit must cover
- The confined space and the work to be done
- Identified hazards and the control measures
- Atmospheric monitoring results (oxygen, flammables, contaminants)
- Who may enter, the standby person, and communication method
- Emergency and rescue arrangements
- The period the permit is valid and sign-off to cancel it
Who issues it?
A competent, authorised person issues and signs the permit after confirming the controls are in place. Workers entering must be trained, and a trained standby person stays outside to maintain communication and trigger rescue if needed.
Why the permit system matters
Confined space incidents often happen because a step was skipped — testing not done, a hazard missed, or no rescue plan. The permit forces every check to happen, in order, and to be documented. It’s a legal and practical safeguard.
Where training fits
Issuing and working under a confined space permit requires nationally recognised training — RIIWHS202E Enter and Work in Confined Spaces. See the Confined Space course → Related permit-to-work skills are covered in issue work permits and gas testing training.
Frequently asked questions
Do you always need a permit to enter a confined space?
Yes — entry to a confined space must be authorised by a confined space entry permit with the required controls in place.
How long is a permit valid?
Only for the period stated on it (typically a single shift or task). Conditions change, so permits are time-limited and must be reissued.
Who can issue a confined space permit?
A competent, authorised person — trained to recognise the hazards and confirm controls.
