Every Australian summer and storm season delivers a fresh round of disaster recovery operations, and with them a predictable spike in asbestos incidents. Damaged fibro cladding, blown-off super six roof sheets, scorched eaves and soffits, vermiculite ceiling insulation exposed to weather: any pre-2004 building that takes a beating from flood, wind, or fire becomes an asbestos management problem until proven otherwise.
If you manage commercial property (particularly older industrial sheds, social housing, regional schools, or community buildings), the question is not whether you will eventually deal with disaster-related asbestos, but how prepared your response will be when it happens. The PCBUs that handle these incidents well have a written playbook before the wind picks up. The ones that handle them badly try to write the playbook while the news vans are arriving.
Why disasters and asbestos are linked
The asbestos materials that survived intact for decades inside a building are often the most fragile once that building is disturbed. Specific failure modes to know:
- Floodwater saturates fibro sheeting, vinyl tile backing, and cement render, accelerating deterioration and, in severe cases, breaking down bonded matrices.
- High winds and hail shatter roof and wall cladding, scattering fragments hundreds of metres downwind.
- Bushfire heat can convert bonded asbestos into a friable state. Even fragments that look intact may no longer meet the non-friable classification.
- Demolition and clean-up by well-meaning volunteers or insurance contractors is often the moment fibres are released, because the original survey is rarely consulted in the rush.
Each of these scenarios converts a managed asbestos risk into an unmanaged one. Your responsibilities under the model WHS Regulations do not pause during an emergency. If anything, the duty to identify, contain, and notify is sharpened by the higher likelihood of exposure.
The first 48 hours: what to do
The single most consequential decision in any disaster-affected building is whether to let people back in. Get that wrong and you've contaminated a workforce, an emergency response team, or members of the public.
1. Secure the perimeter before anyone enters
If the building was constructed or refurbished before 31 December 2003 and the structural envelope has been breached (broken cladding, collapsed ceilings, fire damage to soffits), treat the site as potentially asbestos-affected until a licensed assessor says otherwise. Cordon, signage, and a single controlled entry point are the minimum.
2. Consult the asbestos register before clean-up begins
This is the moment your asbestos register pays for itself. Pull it up before any tradesperson, insurance assessor, or volunteer crew walks the site. Mark on a site plan which materials were already known to contain asbestos, and brief everyone entering accordingly.
3. Engage a licensed asbestos assessor early
Demand for assessors and removalists spikes after a major event, and bookings can blow out to weeks. Get on the phone in the first 24 hours. The assessor's role is to inspect, sample where necessary, and provide written guidance on which materials are safe to handle and which require licensed removal.
4. Notify the relevant regulator
Where licensed asbestos removal is required, the state or territory WHS regulator must be notified before work begins. In disaster zones, regulators are usually accommodating about expedited processes, but only if you call them.
5. Keep insurers in the loop
Most commercial property policies cover asbestos disturbance as part of a broader insured event, but they typically require notification before remediation contractors are engaged. Document everything from the moment of discovery.
Common failures during disaster recovery
Reviewing post-event investigations across recent QLD and NSW floods and the 2019–20 bushfire season, the same mistakes appear repeatedly:
- Volunteer clean-up of asbestos debris. Well-meaning community groups remove broken fibro from kerbs without PPE, contamination controls, or appropriate disposal. This is one of the highest-exposure scenarios in any disaster.
- General builders quoting on full reinstatement without involving an assessor. The work begins, fibres are released, and the property manager is left explaining why no asbestos clearance was obtained.
- Treating fire-damaged bonded asbestos as still bonded. Heat exposure can change the classification. Assume the worst until tested.
- Failing to update the register. Materials are removed or replaced in the recovery rush and the register is never amended. Three years later, the next contractor on site is working from outdated information.
- Improper disposal. Asbestos waste must go to a licensed landfill with proper documentation. "It went out with the rest of the storm debris" is not a defence.
Coordinating with recovery agencies
In larger events, state recovery agencies (NSW Reconstruction Authority, Queensland Reconstruction Authority, equivalent bodies in other states) often coordinate asbestos clearance across affected zones, sometimes with government-funded testing or removal for residential properties. Commercial property managers don't usually qualify for these programs but should still maintain contact: agencies frequently publish updated guidance, approved contractor lists, and disposal arrangements specific to the affected area.
For workplaces, your state WHS regulator (SafeWork NSW, WorkSafe Victoria, Workplace Health and Safety Queensland, and equivalents) is also a useful source of disaster-period guidance.
After the immediate response: updating your systems
Once the site is stabilised, the work isn't over. Disaster recovery should always close out with:
- Updating the asbestos register to reflect any removed, repaired, or newly identified material
- Revising the asbestos management plan if access arrangements or materials have changed
- Filing the clearance certificate from the licensed assessor with site records
- Briefing tenants, staff, and contractors on the changed risk picture
- Reviewing the response with your team and amending your emergency procedures
The takeaway
Disasters do not create new asbestos. They surface the asbestos your building already had, often in the worst possible condition and at the worst possible moment. The PCBUs that come through these events without an enforcement notice, an exposure claim, or a media story share three habits: they keep their asbestos register current, they have an assessor and a removalist on speed-dial, and they refuse to let well-meaning urgency override the basic rules of safe handling. Build those habits before the next event, because the next event is coming.
