Automated Dust Monitors

Automated dust monitors provide real-time data to assist and document dust mitigation at construction sites.  Datasheet

Construction Dust

Dust from demolition, construction, and cleanup activities can significantly impact local air quality, posing a health hazard and a nuisance.
Dust mitigation measures are required at most construction sites, and real-time dust monitoring may be required to verify that mitigation measures are effective. Common parameters include:
  • PM10 - particles with diameters 10 microns and smaller – typically soil.
  • PM2.5 - particles with diameters 2.5 microns and smaller – typically exhaust from heavy machinery.
  • VOCs - volatile organic compounds, potentially harmful gasses, typically emitted from industrial processes.
  • Wind direction and speed.

Dust Monitoring Practices

  • Monitoring should be continuous during working hours and ideally include windspeed and wind direction.
  • Monitoring should provide real-time alerts so that prompt action can be taken if limits are exceeded.
  • Monitors should be placed at the upwind and downwind fencelines of the project to separate project dust from offsite sources of dust.
  • Monitoring should be used to evaluate dust mitigation measures to improve practices and also to reduce costs.
  • Monitoring reports should be stored for easy retrieval in case of complaints.
