EPA Sampling Guide Lines

Asbestos consultants are trained in the proper collection of samples for asbestos analysis. Typical precautions include:


  • Make sure no one else is in the room when sampling is done.

  • Wear disposable gloves or wash hands after sampling.

  • 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.

  • Place a plastic sheet on the floor below the area to be sampled.

  • 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 release of asbestos fibers.

  • Carefully cut a piece from the entire depth of the material using, for example, a small knife, corer, or other sharp object.

  • Place the small piece into a clean container (for example, a 35 mm film canister, small glass or plastic vial, or high quality resealable plastic bag).

  • Tightly seal the container after the sample is in it.

  • Carefully dispose of the plastic sheet. Use a damp paper towel to clean up any material on the outside of the container or around the area sampled. Dispose of asbestos materials according to state and local procedures.

  • Label the container with an identification number and clearly state when and where the sample was taken.

  • Patch the sampled area with the smallest possible piece of duct tape to prevent fiber release.
