The principal benefit of dust monitoring is quantifiable data, removing subjectivity, providing a benchmark from which any action taken can be assessed against.
Dust is typically broken down into two categories; Nuisance Dust (particles over 10 micron in size) and Respirable Dust (under 10 micron). Human health effects of airborne dust are usually associated with respirable dust whilst nuisance dust, as the name suggests is mostly annoying more than anything else. A selection of filters may be fitted to ensure the appropriate range of particle matter (pm) is monitored for your application. Alternatively our recent purchase of the TSI 8533 DustTrak Airborne Particle Counter simultaneously measures PM1, PM2.5, PM4 (Respirable), PM10 and total PM size fractions.
Air Quality Instruments can be used indoors and outdoors (with an enclosure) with monitoring periods between 1 second and 1 hour. Download data and display trends throughout the day/week/month, only limited by the pre-set data capture time.
A few recent uses of our DustTrak Airborne Particle Counter, covering both categories, include:
Complaints were made about the air quality coming into a building. The incoming air was monitored, new filters were installed then the air was monitored again. The difference in the air quality was clear and able to be communicated to all interested parties
Earthworks consent conditions required dust levels to be maintained at no more than the pre-existing conditions (hourly and daily), because of a concern of asbestos contamination. The air was monitored for a month prior to the earthworks commencing, then constant levels were established using this data. Monitoring continued and the customer was able to provide verifiable data that it met the consent conditions throughout
Taken offshore to monitor a contaminated ground site as it was being cleaned up, again to ensure the risk levels were not increased during clean-up
Multiple units attached to boundary fences to monitor air quality as deconstruction/rebuilding occurs following a major fire
