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 ConcentrationStatusImmediate Mandatory Action Required
< 0.01 fibres/mL SafeClean air baseline. Continue standard operational controls.
0.01 to 0.02 fibres/mL WarningEnclosure alert. Review dust suppression and negative-pressure integrity immediately.
> 0.02 to 0.05 fibres/mL CriticalSTOP WORK IMMEDIATELY. Conduct comprehensive engineering inspections for structural containment leaks.
> 0.05 fibres/mL ExceedanceCritical 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.
