This technical webinar features Adrian Eccles and Dawn Anderson from Trolex, providing a comprehensive look at the Air XS—the world’s first real-time respirable crystalline silica (RCS) monitor. This session covers the transition from traditional lab-based sampling to immediate, actionable site data.
The Technology: How Real-Time Silica Detection Works [08:15]
The Air XS utilizes Optical Particle Counter (OPC) technology combined with advanced algorithms to differentiate silica from other dust:
-
Identification vs. Detection: Unlike standard dust monitors that measure total mass, the Air XS identifies the unique "optical signature" of silica particles [10:30].
-
No Radiation Sources: The device is laser-based, meaning it requires none of the complex licensing or safety protocols associated with radioactive XRF sources [12:45].
-
High-Flow Pump: An internal pump maintains a consistent flow to ensure accurate volume sampling across the 0.1 to 10 µm particle size range [14:20].
Compliance and Accuracy [18:50]
How real-time data fits into the current regulatory landscape:
-
The ±25% Standard: The Air XS provides accuracy within ±25% at reference conditions, aligning with NIOSH requirements for workplace monitoring [20:15].
-
Real-Time vs. Lab Results: While lab analysis (NIOSH 7500) remains the regulatory gold standard, the Air XS provides the immediate "missing link" for daily safety management without the 10-day lab delay [23:40].
-
Audit Trail: Every data point is timestamped and logged, providing a defensible record of worker exposure throughout a full shift [26:10].
Field Applications & Best Practices [32:00]
Maximize the effectiveness of the monitor on-site:
-
Placement: The Air XS is designed as an area monitor. Positioning it near the "breathing zone" of a specific process (like stone cutting or tunneling) provides the most relevant data [33:45].
-
Instant Alarms: Configure visual and audible alerts to trigger the moment silica concentrations exceed your set threshold, allowing for immediate evacuation or PPE adjustment [36:20].
-
Maintenance: A look at the "Compliance Check" process—a simple field test that verifies the sensor is clean and functioning correctly in under a minute [40:15].
Data Analysis & Reporting [48:30]
Turning measurements into insights using the Breathe XS software:
-
Direct Export: Connect via USB to download data directly to a PC for analysis in CSV or Excel formats [50:10].
-
Visualizing Exposure: Use the software to graph exposure peaks against specific site activities to identify which tasks pose the highest risk [52:45].
-
Battery Life Management: The unit provides 8–10 hours of runtime, with external battery packs available for 24-hour continuous monitoring [55:10].
