Understanding Dust Monitoring Technologies

Airborne hazardous substances are a critical focus of occupational health and safety, yet aerosol science and measurement technologies can be highly specialised and technically complex. For occupational hygienists and safety professionals responsible for managing a wide range of workplace risks, gaining a practical understanding of dust monitoring methods is essential, but finding the time to develop deep expertise in aerosol science can be challenging. Beyond selecting the right measurement approach, professionals must also efficiently document and report their findings.

This webinar is designed to provide a practical overview of the most common methods used to monitor airborne particulate hazards and to explain the strengths and limitations of each approach. Participants will learn how real-time monitoring data can deliver deeper insight into worker exposures and support more informed decision-making.

The presentation will explore key real-time monitoring technologies, including photometers, optical particle counters (OPCs), and condensation particle counters (CPCs)—highlighting how these methods differ and when each is most useful. Through practical examples, attendees will gain guidance on selecting the right instrument for specific applications and combining complementary technologies to achieve a more complete understanding of workplace exposures.

The webinar will also address an often-overlooked aspect of exposure assessment: documentation and reporting. Modern instruments offer powerful features such as telemetry, data management, and automated reporting tools that can streamline workflows and reduce administrative burden.

Whether you are new to aerosol monitoring or looking to strengthen your understanding of available technologies, this session will provide practical insights to help you choose the right tools and use them effectively in your day-to-day work.
