STEP BY STEP GUIDE
To Sample Collection and Submittal


Sample Collection
(Source: US Environmental Protection Agency)

Note: You cannot be sure that a material contains asbestos by just looking at it with a naked eye. Therefore, treat all suspect material as if they contain asbestos.

  • Shut down any heating or cooling systems to minimize the spread of any released fibers.
  • Do not disturb the material any more than is needed to take a small sample.
  • Wet the material using a fine mist of water containing a few drops of detergent before taking the sample. The water/detergent mist will reduce the possibility of releasing asbestos fibers.
  • Carefully cut/scrape a piece from the entire depth of the material using, for example, a small knife, corer, or other sharp object.
  • Cut/scrape only a small piece of the material. All materials can be grouped into two categories: friable, i.e. the material can be crushed into powder by hand, and nonfriable. These amounts are adequate for testing:

For friable samples - 1 teaspoon
For nonfriable samples - 1 square inch piece


  • Place the small piece into a clean container (for example, a ZipLock bag). Tightly seal the container after the sample is in it.
  • Use a damp paper towel to clean up any material on the outside of the container or around the area sampled.
  • Label the container with an ID number (for example, Sample #1)
  • Submit the sample(s) for testing

Special Notes
  • For acoustic ceiling (popcorn ceiling) material, three separate samples from different locations is strongly recommended if it covers more than 1,000 sq. ft.
  • The mastic or glue/adhesive under floor tile is a separate sample and subject to a separate charge. If some mastic is attached to the tile, that's generally sufficient for testing. No need to scrape a separate mastic/adhesive sample.
  • For Vermiculite insulation, collect at least one tablespoon instead of one teaspoon of material. Sample it from the floor of the attic or the bottom half of the wall cavity. Sampling more than one sample from the attic is recommended.
  • For Dust and Soil/Dirt samples, please follow these instructions

Sample Submittal

  • Place the container with the sample(s) in a suitable mailing envelope.
