Airborne Asbestos Fibre Monitoring & Risk Mitigation
Don't Risk a WorkSafe Shutdown.
Zero Exposure. Total WorkSafe Compliance. Legal Peace of Mind.
Overview
A legally defensible containment-validation framework
Asbestos is the highest-stakes hazard on any Victorian construction site. A single airborne fibre breach can trigger immediate WorkSafe Victoria shutdowns, devastating litigation, and permanent damage to your corporate reputation.
At OmniSense, we don't just hang air pumps; we deploy an elite, legally defensible containment-validation framework. Our operations strictly adhere to the mandatory Guidance Note on Removing asbestos in workplaces Edition 2 (December 2019) to shield your workforce and your business.
Why Choose OmniSense?
When dealing with a Class-A carcinogen, generic monitoring providers leave you exposed. Tier-1 contractors choose OmniSense because we treat environmental compliance as a precision engineering discipline.
Specialist-Led Technical Defence
We provide advanced scientific analysis and site-specific modelling that holds up under strict regulatory and legal audits.
Certified Occupational Hygienists
All testing, positioning, and validation protocols are executed exclusively by qualified Occupational Hygienists.
End-to-End Legal Safeguards
From pre-construction baseline mapping to automated data archiving, we build a seamless digital twin of your site's compliance data to insulate you from future liability.
Precision Protocols: The Membrane Filter Method (MFM)
We maintain a strict chain of custody and rigorous mechanical standards across all critical monitoring phases.
- Pulsation-Free Low-Flow Pumps: battery-operated, highly stable sampling pumps maintaining a strict, continuous flow rate of 1.0 to 2.0 L/min.
- Advanced Particulate Separation: 25 mm conductive plastic cowls paired with gridded Mixed Cellulose Ester (MCE) membrane filters to trap respirable particles.
- True Breathing-Zone Alignment: sampling heads mounted precisely between 1 m and 2 m above floor level and oriented downward to prevent gravity-fed ambient dust contamination from invalidating your samples.
Smart Mitigation: The OmniSense "Zero-Lag" Strategy
The Problem: standard regulatory asbestos testing requires Phase Contrast Microscopy (PCM) in a NATA-accredited laboratory, taking 24 to 48 hours. If an enclosure leaks, you won't know until the damage is already done.
The OmniSense Solution: we co-locate an advanced Real-Time PM10 Dust Monitor directly alongside every regulatory asbestos pump. While a laser photometer cannot physically see asbestos fibres, a sudden spike in ambient dust is a proven Leading Indicator of an enclosure breach or dust-suppression failure.
If PM10 Dust Levels ≥ 1.0 mg/m³
→ IMMEDIATE PROACTIVE WORK STOPPAGE
By stopping work the minute the dust spikes, we protect your workers and correct the source BEFORE the asbestos laboratory samples can return positive.
Action Thresholds & Mandatory Response Matrix
A zero-tolerance scale
We operate on a zero-tolerance scale aligned with the Australian exposure standard.
| Fibre Concentration | Status | Immediate Mandatory Action Required |
|---|---|---|
| < 0.01 fibres/mL | Safe | Clean air baseline. Continue standard operational controls. |
| 0.01 to 0.02 fibres/mL | Warning | Enclosure alert. Review dust suppression and negative-pressure integrity immediately. |
| > 0.02 to 0.05 fibres/mL | Critical | STOP WORK IMMEDIATELY. Conduct comprehensive engineering inspections for structural containment leaks. |
| > 0.05 fibres/mL | Exceedance | Critical Breach. Execute mandatory notifications to WorkSafe Victoria and deploy immediate zone decontamination. |
Premium NATA-Accredited Reporting
Legal-grade certificates, chain of custody
Upon sample completion, cassettes are immediately sealed with specialised plastic caps, barcoded with a unique Sample ID, and couriered under a strict Chain of Custody to our NATA lab partner.
Standard Turnaround
24–48 hour legal-grade compliance certificates.
Emergency Turnaround
Rapid 4-hour priority analysis for critical clearance zones to prevent costly site-mobilisation delays.
