Asbestos Testing

Before collecting any samples, it's crucial to identify materials that commonly contain asbestos. These often include textured paints and coatings, insulation (especially around pipes, boilers, and ducts), vinyl floor tiles and sheeting, asbestos cement roofing and siding shingles, and transite pipes. Look for materials that are deteriorating or show signs of damage. Common in homes built before the 1980s.

To prevent the release and spread of asbestos fibers, carefully seal off the room or area where you will be taking samples. Use painter's tape to close doors, windows, and vents. Lay down 6-mil polyethylene sheeting on the floor extending at least 6 feet around the sampling area. Don personal protective equipment (PPE) including a P100 respirator, disposable coveralls with a hood, and disposable gloves.

Lightly mist the suspected material with water from the spray bottle. This helps to keep the asbestos fibers from becoming airborne. Using a clean tool such as a knife, screwdriver, or pliers, carefully break off a small piece of the material, no larger than a postage stamp. Place the sample into a clean, sealable container, such as a zip-top bag or a small glass jar. Avoid creating dust. Collect a separate sample for each type of material you are testing. Label each sample clearly with its source (e.g., 'living room ceiling tile', 'attic insulation').

After collecting and labeling each sample, securely seal the primary container (zip-top bag or jar). Then, place the sealed primary container into a second, larger zip-top bag and seal that bag as well. This double-bagging helps to ensure that no fibers escape during transport. Wipe down the outside of the outer bag with a damp cloth.

Carefully fold the plastic sheeting inward, away from yourself, to contain any dust or debris. Place the used sheeting, disposable coveralls, gloves, and any other contaminated disposable items into a heavy-duty trash bag. Seal this bag securely. Wipe down any reusable tools with a damp cloth. Remove your PPE carefully, starting with the coveralls, then the gloves, and finally the respirator, ensuring not to spread contamination. Dispose of all contaminated waste according to local regulations, often as hazardous waste. Do not vacuum the area unless you have a HEPA-filtered vacuum designed for asbestos.

Contact an accredited asbestos testing laboratory to confirm their submission procedures, sample requirements, and pricing. Package the double-bagged samples securely for shipping. Include a completed chain-of-custody form or laboratory-specific request form, detailing the samples collected and the information you need from the analysis. Ship the samples via a reputable courier service. Ensure the laboratory is accredited by a recognized body, such as the National Voluntary Laboratory Accreditation Program (NVLAP).
