How to Identify Materials that Contain Asbestos

If you believe asbestos is present in your home or workplace, hire a qualified professional to sample and analyze the material. Choosing a qualified inspector is important, because if sampling is done incorrectly, it can be more harmful than just leaving the material be. Therefore, never take samples yourself. Professionals should note the procedures listed below.

• When the sampling is performed, no one should be present in the room.
• Use gloves during the sampling, or wash hands after.
• Turn off heat or air conditioning to reduce the spread of asbestos fibers.
• Ensure the material is not disturbed any more than is needed for the sample.
• Put a plastic sheet on the floor beneath the sampling area.
• Moisten the material with a mist of water and detergent.
• Excise a piece from the material and place it in a clean container. Seal the container.
• Throw away the plastic sheet.
• Clean up the sampling area and container with a damp paper towel.
• Label the container with information, including where the sampling took place.
• Patch the sampled area with a tiny piece of duct tape.
• Send the container with the sample to an analysis lab. A directory of NVLAP-accredited laboratories can be found at http://ts.nist.gov/nvlap. Your state or local health department may also be able to help.
