Visualization of Dust Generation in Outdoor Workplaces Using A Wearable Particle Monitor and Global Navigation...

Area of Science:

• Environmental Science
• Occupational Health
• Instrumentation Engineering

Background:

• Accurate monitoring of airborne particulate matter is crucial for assessing workplace exposure and environmental impact.
• Existing dust monitoring equipment can be costly and cumbersome, limiting widespread application, especially in dynamic outdoor environments.

Purpose of the Study:

• To develop and evaluate a simple, low-cost wearable particle monitor (WPM) for measuring dust generation.
• To assess the usability of the WPM in conjunction with Global Navigation Satellite System (GNSS) for mapping dust in outdoor workplaces.

Main Methods:

• Manufactured a wearable particle monitor (WPM) and evaluated its measurability against a standard particle counter (KC-52) using standard particles.
• Conducted parallel measurements of dust concentration using WPMs and the KC-52 in a dust exposure apparatus.
• Integrated WPM data with GNSS location information to visualize dust generation in outdoor work environments.

Main Results:

• The WPM demonstrated strong correlation with the KC-52, indicating good measurability of dust concentration.
• A tendency for increased discrepancy among WPM devices was observed as measured values increased.
• Combining WPM and GNSS data enabled the creation of heat maps, effectively visualizing relative dust generation in outdoor workplaces.

Conclusions:

• The wearable particle monitor (WPM) is a useful, low-cost tool for assessing dust generation in various environments.
• The integration of WPM with GNSS provides a practical method for mapping and understanding dust emission sources in outdoor workplaces.
• This approach offers a valuable overview of conditions contributing to dust emissions in occupational settings.
