How to Take Asbestos Samples

Asbestos is a mineral that was used for insulation in many buildings across the United States. However, asbestos releases dangerous fibers that can sicken or kill those who inhale them. Taking a sample of asbestos for analysis is somewhat of a delicate task, but armed with knowledge and following all proper procedures, it can be done safely and correctly.

• 1

  Shut down all systems that circulate air. Place plastic gloves on your hands, and make sure your clothing does not reach over your wrist. If desired, a plastic tarp may be placed under the asbestos material. Contact should be kept to an absolute minimum with the substance itself, due to the toxic effects of inhaling microscopic asbestos fibers.

• 2

  Fill the spray bottle with water and add a small amount of detergent. Spray this mixture over the entirety of the exposed asbestos, and primarily over the area you will sample from. The material should be only very slightly damp; even a small amount of liquid will help cease fiber release.

• 3

  Cut a small piece of the asbestos away from the main body using a sharp knife. The sample should include approximately a square inch and the entire depth of the material. Place the sample into the resealable bag and close it tightly and completely.

• 4

  Dampen the paper towel and wipe off the surfaces around the asbestos. Wipe off the outside of the plastic bag, especially any part of the bag that may have come into contact with the sample. If a tarp was used, remove it and wash it thoroughly. Wash the knife. Remove the plastic gloves and dispose along with the paper towels. Check state regulations regarding disposal of material in contact with asbestos.

  Label the plastic bag with a permanent marker, indicating where and when the sample was taken. Store carefully or deliver to an agency for testing.
