asbestos containment
Professional containment, HEPA filtration and secure disposal to stop asbestos fibres spreading.
C&A Asbestos Removal provides licensed containment services across Australia. When asbestos work is needed—whether in a home, strata building or small commercial site—proper containment prevents fibre release and keeps people safe. We design containment plans, install sealed enclosures and use negative-pressure HEPA filtration before, during and after removal.
Licensed, compliant and fully documented — we follow Safe Work Australia guidance.
Why professional asbestos containment is essential
Asbestos fibres are microscopic and can remain airborne for long periods if disturbed. Without properly designed containment and filtration, removal work can spread contamination throughout a property and pose long-term health risks to occupants and neighbours.
Our containment service reduces airborne fibre release by combining sealed enclosures, negative-pressure systems, continuous HEPA filtration and strict decontamination procedures. This approach protects people, other trades on site, and prevents cross-contamination.
- Minimises airborne fibres during disturbance
- Full documentation and disposal dockets provided
- Trained technicians following Safe Work Australia code
Our containment measures — how we prevent fibre release
We design a bespoke containment plan for every site, using layered controls to stop asbestos fibres from escaping the work area.
Sealed enclosures
We erect physical barriers using certified polyethylene sheeting, taped seams, and purpose-built access points to isolate the work zone from the rest of the property.
Negative-pressure systems
Portable negative-pressure units maintain inward airflow into the enclosure, preventing dust and fibres from escaping into adjacent spaces.
Decontamination setups
Entry and exit decontamination units are installed where required so technicians can safely remove PPE and prevent carry-out contamination.
HEPA filtration & continuous monitoring
We run certified HEPA air filtration units during and after removal. Where required, we coordinate independent clearance air monitoring with a hygienist to confirm safe re-occupation.
PPE and trained technicians
All work is carried out by licensed technicians wearing appropriate respiratory protection, suits and gloves. We follow Safe Work Australia PPE guidance at all times.
Secure packaging & disposal
Removed material is double-bagged, labelled and transported to EPA-licensed facilities. You receive full waste dockets and disposal records for compliance.
How HEPA filtration protects occupants
HEPA (High Efficiency Particulate Air) filters remove at least 99.97% of particles down to 0.3 microns. During asbestos work we use certified HEPA units as part of a negative-pressure system to continuously clean room air and capture fibres before they migrate outside the containment.
HEPA units are correctly sized for the work area, positioned to maximise airflow through the enclosure, and run until independent clearance criteria are met or the site is handed back clean.
- Continuous filtration throughout removal
- Post-clean filtration before re-entry
- Coordinated independent clearance testing when required
Containment process — what to expect
Site assessment & containment design
We assess access, proximity to occupied areas and ventilation to design the appropriate enclosure and filtration layout.
Set up enclosure & negative pressure
We erect sealed barriers, install negative-pressure and HEPA units and set up decontamination zones before any disturbance.
Controlled removal using wet methods
We use wet methods to suppress dust, remove material and package waste in double-lined bags for transport.
Clean, filter and clearance
After removal we deep clean the area, run HEPA filtration and coordinate independent clearance testing if required before handback.
Secure transport & disposal
All waste is transported to EPA-licensed facilities and you receive full disposal dockets and a job completion report.
Frequently Asked Questions
What is a containment enclosure and when is it needed?
A containment enclosure isolates the work area using taped polyethylene barriers, sealed openings and controlled access. It is required whenever asbestos-containing material will be disturbed in a way that could release fibres into occupied spaces or adjacent areas.
How does HEPA filtration work in asbestos jobs?
Certified HEPA units draw air through ultra-fine filters that capture particles down to 0.3 microns. In asbestos work they are used inside negative-pressure setups to prevent fibres from escaping and to clean air after removal prior to clearance testing.
Will you provide disposal paperwork?
Yes. Every job includes EPA-compliant disposal dockets and a job completion report showing waste tracking and handling. Documentation is provided for your records and any regulatory requirements.
Can the area be used immediately after removal?
Re-occupation depends on the work and clearance results. We run HEPA filtration and cleaning, and where required we coordinate independent air monitoring. You will be advised when it is safe to re-enter.
