air testing after asbestos removal
Independent clearance testing, accredited laboratory analysis and compliance certificates you can rely on.
C&A Asbestos Removal coordinates third-party air monitoring and issues formal clearance documentation after every removal job — giving homeowners, strata managers and business owners confidence to re-occupy safely.
We coordinate accredited, third‑party clearance testing to Australian guidance.
Why post-removal air testing is essential
After asbestos removal, visual cleaning alone does not guarantee that airborne asbestos fibres are below safe levels. Clearance testing confirms the work meets regulatory expectations and gives property owners documented evidence that the site is safe to re‑occupy.
- Independent verification that airborne fibre concentrations meet accepted criteria
- Laboratory analysis with chain-of-custody and formal reporting
- Compliance documentation for conveyancing, tenants, insurers and regulators
What our clearance testing covers
We work with independent occupational hygienists and NATA‑accredited laboratories to provide a full clearance pathway tailored to the scope of removal.
Air Monitoring (PCM / TEM)
Personal and area air samples collected using calibrated pumps and analysed by microscopy methods to quantify fibre concentrations.
We advise the appropriate sampling method (PCM vs TEM) based on the risk and regulator expectations for your job.
Visual Clearance Inspection
A qualified hygienist performs a structured visual inspection to confirm the work area has been cleaned and that removal controls were effective.
Visual checks complement air monitoring and are documented in the clearance report.
NATA‑Accredited Laboratory Analysis
Samples are shipped under chain of custody to NATA‑accredited labs for timely, defensible results you can trust.
Lab reports include methods used, detection limits and interpretation guidance.
Clearance Certificate & Report
You receive a formal clearance certificate plus a detailed report summarising sampling locations, results, chain of custody and recommendations.
Documents are provided for records, conveyancing, or regulator requests.
Third‑party independence and accreditation
C&A coordinates independent occupational hygienists for air monitoring and engages NATA‑accredited laboratories for analysis. Independent testing removes any conflict of interest and provides robust evidence of compliance.
- Independent occupational hygienists with field experience in asbestos clearance
- Samples analysed by NATA‑accredited labs using recognised microscopy methods
- Full chain-of-custody, lab certificates, and a clearance certificate delivered after review
How air testing after asbestos removal works
Book testing when removal is scheduled
Tell us your removal date and scope. We schedule an independent hygienist to attend immediately after cleaning is complete.
Visual inspection and sample collection
The hygienist performs a structured visual inspection and collects area and/or personal air samples using calibrated pumps and cassettes.
Lab analysis and reporting
Samples are couriered to a NATA‑accredited lab. Results and interpretations are reviewed by the hygienist and compiled into a clearance report.
Clearance decision and certificate
If results meet clearance criteria, you receive a formal clearance certificate and full documentation. If not, the report outlines further actions required.
Frequently Asked Questions
Do I always need air testing after asbestos removal?
Clearance testing is commonly required for Class A asbestos removal and for situations where proof of safe re-occupation is needed (e.g. conveyancing, tenancy handover, commercial re‑opening). We assess your job and advise whether air monitoring and a clearance certificate are recommended or required.
Who performs the air testing and analysis?
We arrange independent occupational hygienists to collect samples and use NATA‑accredited laboratories for analysis. Independence and accreditation ensure defensible, third‑party results.
How long does testing and reporting take?
Sample turnaround varies by method and lab workload. Typical microscopy results are available within 1–5 business days; express options may be available for urgent jobs. We provide estimated turnaround when booking.
What happens if the site fails clearance?
If results exceed clearance criteria, the hygienist will recommend re‑cleaning and often repeat sampling. C&A will assist with remediation and re-testing until compliance is achieved.
