To Sample Collection and Submittal

Sample Collection

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 (e.g Acoustic ceiling spray), and nonfriable (e.g. Floor tile, Siding). 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 samples from different locations is strongly recommended if it covers more than 1,000 sq. ft (the total cost for three samples is $90).
  • The mastic or glue/adhesive under floor tile or linoleum is a separate sample and subject to a separate charge.  (the total cost for flooring and adhesive is $60).  Do not scrape the adhesive, just send an approximately square inch size sample with attached adhesive/masti.  As long as the adhesive is visible under the flooring material, we'll separate it ourselves. 
  • For vermiculite insulation, collect at least one cup size sample. Take a sample from the attic floor or the bottom part of wall cavity. Testing at least two samples from different spots in the attic is recommended.
  • Do not send Dust or Soil/Dirt samples.  These cannot be accurately analyzed by Polarized Light Microscope (PLM).  Dust samples require analysis by Transmission Electron Microscope (TEM) which we currently do not provide.  

Sample Submittal and Payment

  • Place the container with the sample(s) in a suitable mailing envelope.
  • Please fill out an Electronic Submittal Form.  As long as your name is on the shipping envelope and/or sample bags, we'll connect your form to your samples.  If you prefer not to send you info online, use either the Html Submittal Form or the PDF Type-able Form to include with your sample(s).
  • Enclose your payment (money order or a personal check) of $40 for one sample and $30 each for two or more samples
  • If you prefer to pay by credit card, please follow this link for a secure online transaction.
  • International customers should follow the credit card payment link above.
