Know your confined space controls work
Confined spaces are among the highest-risk work environments on any site. Under the WA work health and safety regulations, a business must identify its confined spaces, manage the risks, and control entry through permits, gas testing, standby and rescue arrangements.
An STES confined space audit is an independent, on-site review of how your site does this in practice. You receive a written report of what is working, what is missing, and the actions to close the gaps.
What the audit covers
Register and risk assessments
Whether every confined space is identified, signed and recorded, with a current risk assessment and entry procedure that reflects how the work is really done.
Permits and gas testing
How entry permits are issued and closed out, checked against recent permits, plus gas detector calibration and bump test records, ventilation and breathing apparatus.
Rescue and competency
Standby arrangements, rescue plans and equipment, whether rescue has been practised, and whether entrants, standby people, gas testers and permit issuers hold current training.
How it works
Scope the audit
We agree the site, the spaces and the systems to be reviewed, and the documents we need beforehand.
Document review
We review your register, procedures, risk assessments, permits and training records.
On-site inspection
We inspect a sample of spaces and observe how entry is controlled on the day.
Report and actions
You receive a written report with findings ranked by risk and practical actions to address them.
Confined space training
If the audit finds training gaps, we can close them with nationally recognised courses, at our centres or on your site.
Frequently asked questions
Why have an independent audit?
An outside reviewer sees the gaps that are easy to miss from inside the business, and a documented audit shows that you are actively checking your controls work.
How long does an audit take?
It depends on the size of the site and the number of confined spaces. We confirm the time on site and the report date when we scope the audit.
Can you train our people after the audit?
Yes. STES delivers confined space entry, gas testing and breathing apparatus training, at our Perth centres or on your site.
