Asbestos competent person: who can sign off a clearance
On a bonded job a competent person may issue the clearance. On a friable job it must be a licensed assessor. Either way, they cannot be the removalist.
For bonded (non-friable) asbestos removal, a competent person can issue the clearance certificate. For friable removal, it must be an independent licensed asbestos assessor. That is the short answer. And the rest is about what “competent” has to mean in practice.
What a competent person is for
After a removal job, someone has to inspect the area and confirm no visible asbestos residue or dust is left. That inspection ends in a clearance certificate. On a bonded job, the person who signs it can be a competent person rather than a licensed assessor.
It does not make the job optional. It just widens who may do the check. Your state or territory regulator sets the exact wording of what counts as competent, so check it before you hire anyone.
Independence matters more than the title
The inspector must not have done the removal work. They must also not be part of the business that did it. SafeWork NSW says the same test covers perceived conflicts of interest, such as a relative, a friend or a regular working partner of the removalist.
So the removalist cannot sign off its own work. If the person who pulled the sheets down also writes the certificate, you do not have a clearance. You have a promise.
When it has to be a licensed assessor
Friable removal is the line. Clearance certificates for any friable job must come from an independent licensed asbestos assessor. Friable work is Class A licensed work in every case, and it also needs air monitoring.
Unsure whether your job is bonded or friable? Assume the stricter route until a licensed professional tells you otherwise. A sample analysed at a NATA-accredited laboratory is how the material itself is identified.
What to ask before you accept a certificate
Ask who inspected, and whether they were independent of the removalist. Ask what training or licence they hold. Ask where the certificate says the inspected area starts and ends.
Then file it with the survey and lab reports. For the full sign-off process, read air monitoring and clearance. If you are weighing who may do the work itself, see asbestos law by state.
Frequently asked questions
What is an asbestos competent person?
Someone with the training, knowledge and experience to inspect an area after removal work and confirm no visible asbestos residue remains. Your state regulator sets what counts as competent.
Can a competent person issue a clearance certificate?
For non-friable (bonded) removal, yes: either a competent person or an asbestos assessor may issue it. For friable removal it must be an independent licensed asbestos assessor.
Can the removalist sign off their own job?
No. The inspector must not have done the work or be part of the business that did it, and perceived conflicts of interest count too.
Does a clearance confirm the material was asbestos?
No. Only a sample analysed at a NATA-accredited laboratory identifies the material. A clearance records that the area was left clean.
