How to Identify Asbestos

In the past century asbestos was used in a myriad of products to make them stronger, more resistant to fire and less costly. However, exposure to asbestos-containing airborne fibers can lead to lung diseases such as asbestosis and mesothelioma.

Certain of these diseases could have a long latent period. It can be difficult to recognize a problem until it's too far gone.

Identifying Asbestos

Asbestos is a group of naturally occurring minerals that were once used in building materials as they are fire-resistant, corrosion resistant and insulation. It could, however, pose health risks when the microscopic fibers inhaled. This is often the cause of diseases like asbestosis and mesothelioma. The symptoms of these illnesses don't show up until years, or decades, after the initial exposure and are often misinterpreted as flu-like symptoms. It is essential that people know how to identify the asbestos.

The most commonly used method to detect asbestos is by medical tests that check for lung disease. These tests usually include a physical examination or chest Xrays as well as lung function tests. However, asbestos-related illnesses aren't identified by these tests on their own, since they need to be combined with a thorough health history that examines a person's home, work and cultural environment.

Asbestos can be found in a variety of construction products and materials, including cement, paints, and floor tiles. It is also found in insulation, doors and partitions, cladding and Artex. However, asbestos is difficult to recognize since the dangerous fibers are so tiny and light that they can easily flounder in the air and be inhaled without being noticed. They don't have distinctive smells, either.

You can take a small sample if you suspect that a material contains asbestos. This should only be performed by a professional who is trained, since removing asbestos is extremely complicated and requires specialized equipment. Send the sample to an accredited asbestos analysis laboratory through the National Voluntary Laboratory Assessment Program (NVLAP). The NVLAP website provides a list of accredited laboratories.

It's easy to accidentally damage asbestos and the chance of doing this can be much higher for certain groups of people. This includes plumbers, construction workers, and electricians as they are more likely to encounter asbestos-containing products during maintenance and renovations. Any person who works in these fields should attend an asbestos awareness course to ensure that they are aware of the risks and are aware of the proper precautions.

Doing Samples

For asbestos testing or inspection an asbestos sample of the suspected material is required. The sample can be collected by an asbestos expert or by the homeowner, but careful consideration should be taken to minimise the generation of dust containing asbestos that is airborne both during the collection of the sample as well as when cleaning up afterwards. The person who is taking the sample will typically need an air vacuum cleaner that is HEPA-filtered and a spray bottle of water, and disposable covers for protection. They must also wear a respirator that conforms to AS/NZS1716.2003 Respiratory safety devices when performing the task. It is best to conduct the sample collection on a non windy day, and ensure that heating or cooling systems are shut off, so that there is less chance of release of any airborne asbestos particles.

When collecting the sample, make sure that the area is sealed off and that no children or pets can enter. The area to be sampled with a damp rag, and clean the tools and equipment that were used after the sample is completed. Place the cloth in a plastic bag and label it as contaminated waste and dispose of it at an asbestos disposal facility that is approved. Place the re-sealable bag containing the sample inside a different plastic bag, then seal it all before declaring it asbestos waste. Put a dropsheet of plastic on the area that must be cleaned. Then, wet it down once more. This will capture any fibres that are released.

Asbestos is usually collected using a pre-assembled pump as well as a cassette system. It is vital that the cassette isn't overloaded with dust, since this could block the fibers on the filter and create an imbalance in the results. If the sample was taken in an area where there are significant levels of non-fibrous dust, it could be necessary to use less air.

While the majority of research focuses on asbestos fibers that are long however, epidemiological studies have found that exposure to short asbestos fibers may cause mesothelioma or lung cancer as well. This suggests that size is just one of the factors that affect asbestos fibers' pathogenicity and that other factors such as chemical properties, dispersion staining, polarization, and etching time are as well.

Identifying Professionals

Asbestos fibers may become airborne when they are disturbed or spread. These microscopic fibers, once inhaled, can cause lung diseases. These can lead to mesothelioma and asbestosis as well as other respiratory and neurological problems. Many symptoms may manifest after 20 to 50 years.

Infrequently disturbed asbestos does not pose an health risk, however when the insulation, shingles, and flooring get damaged or wear out they could release harmful fibers. This could happen when you are working on a renovation or demolition project or even in regular home usage or aging.

If you are planning to remodel your home, make sure you check with local environmental or health officials to determine if the structure has asbestos-containing materials. If asbestos is discovered in your home, it is recommended to have it inspected before any work starts by an accredited Asbestos Settlement inspector.

If you are renovating an older house ensure that the contractors you hire have the required qualifications. They should be able supply an asbestos attorney report and survey which includes an assessment on the condition of any ACM (asbestos-containing material) and their brittleness. The survey should also state whether the contractor plans to remove or leave the ACM intact.

Minor repairs are feasible on certain ACM. However only a professional who is educated in the safe handling of asbestos should attempt these. No matter what type of repair is completed the area should be protected from the rest of your home. Any clothing or equipment should be placed in plastic bags and labeled with a warning to prevent cross-contamination.

Professionals can cover or seal ACM to prevent it from releasing fibers into the environment. Sealing (encapsulation) involves treating the material with a substance which binds or covers the fibers to keep them from becoming airborne. This can be done to insulated piping or to cover old shingles.

Professionals can also physically remove ACM. This is accomplished by wetting the materials to allow them to be scraped or cut with many tools, without releasing harmful fibers. The materials are then put in airtight, tough containers that are leakproof.

Repairing or removing Asbestos

Asbestos is abrasive to corrosion and heat and has been an extremely useful material for thousands of products such as walls, fireproofing materials and auto brakes. Asbestos can be a poisonous material that can cause respiratory issues when fibers are breathed in. Typically, these fibers get trapped in the lungs. They can lead to scarring and inflammation of the tissues, which can hinder breathing and cause serious health issues.

Asbestos can be found in numerous areas of a home such as roof shingles, cement pipes and floor and ceiling tiles, as well as joint compound containing asbestos. It is important to inspect these areas regularly for tears, abrasions or damage. Slightly damaged material may be safe if it is not manipulated or damaged. However, if the material is damaged or you plan to make changes in your home that might disturb it, you should speak with an asbestos expert.

These professionals can conduct an inspection of the visuals and take samples. They can also offer suggestions on what adjustments are required and who qualifies. It is crucial to have only these experts manage your asbestos. These professionals are educated in specific products and should be allowed to correct them.

In addition to consulting with a trained asbestos lawyer professional You should also contact your state or local health department or regional office of the U.S. Environmental Protection Agency to inquire about asbestos-related training programs in your area. Be aware that there are firms which falsely claim they specialize in asbestos removal. These firms pose a threat as they encourage or conduct unnecessary removals, increasing the likelihood of harmful fibers being released.

The American Lung Association does NOT endorse these companies. Before hiring an asbestos specialist, it is important to conduct a thorough investigation of the company to make sure it's properly certified and insured. You can also ask for references from previous clients, as well as confirmation of accreditation and insurance coverage. You should also check with your state or local health and environmental departments to determine the best steps to follow if intend to remodel your home.
