Indoor Dust Sample Collection

If it is important to assess the potential for contaminant transfer via airborne dust, surface soils should be collected for assessment. Often this material will be derived from indoor floor sweepings. If possible, utilize the broom normally used at the location. Collected material should be transferred to a single 125 or 250ml pre-labeled glass jar.

If practical, material should have a high proportion of small particulates. If not, additional pre-labeled glass jars should be filled. At a minimum, protective glasses, gloves and a respirator should be worn by sampling staff during dust sample collection for safety purposes. Try to avoid creating airborne dust while collecting this sample.

Pre-sampling Preparation

  • Locate site
  • Fill out data sheet (use soil data sheet)
  • Prepare sampling jars
  • Wear a dust mask

Clean Sampling Equipment

  • Put on gloves, rinse gloves with clean water
  • First scrub equipment with sparkleen
  • Rinse with clean water (3x)
  • Rinse with acetone
  • Rinse with hexane

Sample Collection

  • Use a broom on site to collect a small pile of dust to sample
  • Preferably do not sample from an existing pile
  • Collect one sample per room
  • Homogenize dust sample in stainless steel tray
  • Transfer samples to pre-labeled bottles
  • Do a final check to ensure that the labels and field sheet are complete

Final Checks

  • Ensure that jar and lid are labeled correctly;
  • Secure the label with clear plastic tape around the jar;
  • Put the jar into the cooler; and
  • Ensure that the field data sheet has been completed, including photos, site map sketch and GPS readings.
