Case Study: Emergency Asbestos Make-Safe Industrial Facility

Emergency Project Metrics

✓ Response Time: First hazmat containment response crew on site within 90 minutes of initial callout.

✓ Containment Scope: 650m² of fractured asbestos wall and eave sheeting sealed with tinted bonding agent, exclusion zones established, HEPA air filtration deployed.

The Emergency Incident

During a severe November supercell storm in Archerfield, Brisbane, microburst winds exceeding 115 km/h sheared tree branches directly into the western gable and eave cladding of a commercial distribution warehouse. Over 650m² of brittle chrysotile/amosite asbestos sheeting shattered, showering debris across the dispatch yard and internal packing bays.

With 45 warehouse workers on shift and delivery trucks arriving continuously, the site was facing immediate WorkSafe closure.

The 24/7 Alliance Response Action

Immediate Site Evacuation & Lockdown: Duty supervisor arrived at 11:30 PM, established a 25-metre exclusion boundary, and locked down HVAC air systems.
Aerosol PVA Fiber Suppression: Applied tinted polyvinyl acetate (PVA) mist over all fractured edges and ground debris to lock fibers in situ.
Internal Polyethylene Airlock Containment: Constructed negative-pressure plastic containment barriers between the packing floor and the damaged wall.
Emergency Weatherproofing: Installed heavy-duty reinforced tarpaulins with timber battens across the exterior breaches before secondary morning rains hit.

Operational Handover in 18 Hours

By 4:00 PM the following afternoon, independent air monitoring confirmed background levels (<0.01 fibres/mL). An interim Clearance Certificate for internal areas was issued, allowing the client to safely resume dispatch operations with zero lost revenue.
