How to Identify Asbestos
During the last century, asbestos was used in a variety of products to make them more durable, less prone to fire and less expensive. Exposure to asbestos fibers in the air can cause lung diseases like asbestosis or mesothelioma.
Some of these illnesses can have a long latent period. This means it is difficult for people to spot the issue before it's late.
Identifying Asbestos
Asbestos is a class of naturally occurring minerals that were once used in building materials because they are fire-resistant and corrosion resistant, as well as an insulator. It can, however, pose health risks when the microscopic fibers are breathed in. This could lead to illnesses such as mesothelioma or asbestosis. The symptoms of these diseases do not manifest until years, if not decades after initial exposure. They're often mistaken for flu-like symptoms. This is why it's crucial for people to know how to identify asbestos.
Medical tests to check for lung diseases are the most common way to determine if you have asbestos. These tests typically include physical examinations or chest Xrays as well as pulmonary function tests. However, asbestos-related diseases aren't diagnosed using these tests on their own, since they have to be taken with a thorough patient history which includes a thorough examination of a person's work, home and their cultural surroundings.
Asbestos can be found in a variety of building products and materials, including cement, paints and floor tiles. It is also present in doors, insulation and partitions, cladding and Artex. However, asbestos can be difficult to detect because the fibers that pose danger are so tiny and light that they can easily flounder in the air and inhale without being noticed. They don't have distinct smells either.
If you suspect a material might contain asbestos, you can take an atom of it. It is important that you only use a professional to remove asbestos, as it is an intricate process that requires special equipment. Patch the sample with duct tape to prevent the release of fibers and send it to an asbestos analysis lab accredited by the National Voluntary Laboratory Accreditation Program (NVLAP). The NVLAP website provides a list of accredited laboratories.
It is very easy to accidentally alter the asbestos in a way and the risk of doing this can be higher for certain categories of people. Plumbers, asbestos construction workers, and electricians are at risk of exposure to asbestos during renovations and maintenance. It's a good idea for all workers in these areas to take an asbestos awareness training course so that they understand the dangers and can use the proper precautions.
Take Samples
To conduct asbestos testing or an inspection for asbestos testing or inspection, a sample of the suspect material is needed. The sample can be taken by an asbestos expert or a homeowner. However it is crucial to ensure that you don't generate airborne asbestos-containing dust during the collection and cleaning process. The person taking the sample will typically need an air vacuum cleaner that is HEPA-filtered along with a spray bottle of water, and disposable covers for protection. They must wear a respirator that conforms to AS/NZS1716.2003 Respiratory protective devices when performing the task. It is recommended to carry out the sample collection on a not stormy day. Also, ensure that heating or cooling systems are shut off, as this will minimise the release of any asbestos-containing airborne particles.
When you collect the sample, make sure that the area is closed off and that any children or pets are not allowed to enter. Wet down the area to be sampled with the help of a damp rag. Then, clean all equipment and tools that were used during the sampling process after it has been completed. Place the rag in the bag, label it as asbestos waste, and dispose of it in an asbestos-free facility that is approved by the government. Place the re-sealable bag containing the sample in a separate plastic bag, and seal it up before labelling it as asbestos waste. Wet down the area to be cleaned again and then place a plastic drop sheet over it to catch any fibres that escape.
Asbestos is typically removed using a pre-assembled pump and cassette system. It is crucial that the cassette does not get filled with dust since this could block the fibres on the filter and create a bias in the result. If the sample was taken in an area with significant levels of nonfibrous dust could be necessary to use smaller volumes of air.
The epidemiological studies showed that asbestos fibres with a shorter length can also cause mesothelioma and lung cancer. This indicates that size isn't the only one factor that influences asbestos fibers' pathogenicity and that other parameters like chemical properties like dispersion staining, dispersion polarization and etching times are as well.
Identifying Professionals
When asbestos fibers are disturbed or spread they can end up becoming airborne. These microscopic fibers when inhaled, can cause lung disease. These microscopic fibers can cause asbestosis or mesothelioma, as well as other respiratory and neurological disorders. The symptoms can manifest from in the 20 to 50 years following.
Undisturbed asbestos does not pose the risk of health hazards, but when materials like insulation, shingles and flooring become damaged or degraded, they can release the harmful fibers. This can happen during a renovation or demolition project, as well as during normal home use or when the material ages.
If you plan on remodeling your home, check with local officials from the environmental or health department to determine if the building has asbestos-containing materials. If any asbestos-containing material is discovered and inspected, you must have it checked by an asbestos inspector who is accredited prior asbestos to beginning any work.
If you are renovating an older house, make sure any contractors you employ have the appropriate qualifications. They should be able supply an asbestos report and survey that includes an assessment on the condition of any ACM (asbestos-containing material) and their brittleness. The survey should also state whether the contractor will take away or leave the ACM intact.
Minor repairs might be possible with certain ACM repairs, but only a trained professional who knows the techniques for handling asbestos safely should attempt them. Whatever the kind of repair, the affected area should be sealed off from the rest of the home and any contaminated equipment or clothing should be put in plastic bags and marked with a warning so as to avoid cross-contamination.
Professionals can seal ACM or cover it to stop the fibers from being released into the air. Sealing (encapsulation) involves treating the material with a chemical that binds or coats the fibers to prevent them from becoming airborne. This can be done on insulated piping, or to cover old shingles.
Professionals can also physically remove ACM. The materials are first wetted to allow them to be cut using various tools without releasing dangerous fibers. The material is then placed in airtight, sturdy containers that are leak-proof.
Removing or replacing Asbestos
Asbestos is invulnerable to heat and corrosion and has been an extremely useful component in hundreds of products, including wallboards, fireproofing insulation and auto brakes. Asbestos is a harmful substance that can cause respiratory issues when fibers inhaled. In most cases, these fibers end up lodged in the lungs and may cause tissue inflammation and scarring which can impair breathing and cause serious health problems.
Asbestos is present in many areas of a house such as roof shingles, cement pipes flooring and ceiling tiles, as well as joint compound that contains asbestos. It is important to inspect these areas frequently for tears, abrasions, or water damage. If the material is only slighty damaged, it might be safe to touch or even disturb. If the material needs to be repaired or replaced, or you are planning to make changes to your home that could affect it, then consult with an asbestos professional.
These professionals can perform a visual inspection and also take samples. They can also advise you on the corrections that must be done and who is qualified to carry out them. It is important that you let these experts manage your asbestos. These professionals are trained in specific products and should only be allowed to correct them.
You can also contact your local or State Health Department or Regional Office of the U.S. Environmental Protection Agency to inquire about asbestos training programs offered in your region. Also, be aware of the many companies that falsely claim to specialize in asbestos removal. These firms can be dangerous since they encourage removals that are not needed or do them incorrectly and increase the risk of release of harmful asbestos fibers.
The American Lung Association does NOT endorse these companies. It is essential to do your research thoroughly before hiring an asbestos professional to ensure that they are fully insured and certified. You can also request references from former clients, as well as proof of accreditation and insurance coverage. You should also consult your local or state health and environmental agency to determine the best guidelines to follow if you intend to remodel your home.
