Asbestos is a heat-resistant fibrous silicate mineral that may be found in ceiling tiles, floor tiles, insulation, cement siding, and a variety of other building materials. Although some applications of asbestos are prohibited in the United States, many others remain allowed. Furthermore, asbestos is not prohibited in many nations.
Asbestos Testing Procedures
- Do not disrupt the area you are testing in any way – If asbestos is present in the surface dust, do not attempt to clean any object or location from which you want to obtain a sample. Ensure that there is no moving air in your workspace to prevent tiny fibers from becoming airborne. Turn off any fans, heaters, and air conditioning systems that circulate air and close all windows and doors.
- Put on some disposable protection gear – Put on your full protective gear, including a face mask, gloves, coveralls (or long sleeves and pants), and shoe coverings. During asbestos removal, you’ll need to discard whatever you’re wearing, so investing $5 to $10 in disposables is well worth it. No one should be allowed in the area unless they are wearing protective gear.
- Using plastic sheeting, cover the work area and spritz all surfaces with water – Cover the work area with plastic sheeting to capture any asbestos dust that may settle. Spray the entire space with water until all surfaces are misted and the air is humidified. This will guarantee that any disturbed dust settles fast.
- Isolate a material sample with care and spray it with water – Use a utility knife or chisel to loosen a sample of the material you want to test as quietly as possible to reduce dust. The weight of the sample must be between 5 and 100 grams (just about 1/4 pound). Spray the loosened sample with water and spritz the air around you without touching it.
- Transfer the sample to a zip-lock plastic bag using covered pliers – In the mouth of the pliers, place a moist wipe to keep minute fibers from clinging to the pliers. With the pliers, carefully pick up the sample and place it into a zip-lock plastic bag. Add the moist wipe to the mix as well.
- The zip-lock plastic bag should be sealed and labeled – Close the plastic bag and seal it. Print the following information in tiny characters at the top of the bag: where the sample was obtained, when it was taken, and what the sample comprises. Place this sealed bag into a second zip-locking plastic bag to keep it safe. Once more, mist the air to ensure dust settles.
- Vacuum the testing area and dispose of the vacuum’s contents safely – Vacuum the area thoroughly. Replace the vacuum bag gently and dispose of the old ones in a plastic garbage bag, tape the bag close to trap particles as you did with the plastic sheet. If you’re using a bagless vacuum, place the canister inside a garbage bag and tap out any dirt and dust carefully. Wipe the canister down completely with a moist towel. Use a plastic garbage bag to dispose of this cloth. To be sure, wipe clean the surface with a moist wipe or two. Dispose of these items in the same manner as the rag.
- Clean the area with dampened cloths, then dispose of the cloths gently – With another damp rag, clean the whole work area as well as any neighboring areas where dust may have settled. Dispose of the rag in the same manner as the others, and tape the bag shut.
- Remove and discard the protective gear you wore during the process with care – Remove your coveralls or clothing, as well as your facemask and gloves, and place them in the garbage bag with the paintbrush before taping it shut. Ensure that all rubbish is properly disposed of.
Therefore, asbestos testing is safe as long as it is contained inside the materials in which it is utilized. When such materials collapse as a result of aging or are disturbed during renovations or destruction, the fibers can enter the air and pose a major health risk.
