How to Identify Asbestos

Over the course of the last century, asbestos was used in a variety of products to make them more durable, less prone to fire and less expensive. But exposure to asbestos in the air fibers could cause lung diseases such as asbestosis and mesothelioma.

Certain of these diseases could have a long latent period. It's hard to spot the presence of a problem until it is too long gone.

Asbestos Identification

Asbestos is one of the naturally occurring minerals that were once used in building materials due to the fact that they are fire resistant, corrosion resistant and insulation. Inhaling the microscopic fibres can be harmful to health. This can lead to the development of diseases such as asbestosis and mesothelioma. The symptoms of these illnesses don't manifest until years, if not years after the initial exposure. They're often misinterpreted as flu-like symptoms. This is why it's important for people to be aware of how to identify asbestos.

Medical tests that check for lung disease are the most commonly used method to detect asbestos. These tests usually consist of physical examinations, chest X-rays and lung function tests. These tests are not enough to detect asbestos-related diseases. They should be paired with a complete history of the patient that includes details about the patient's work, residence, and cultural environment.

It's possible to detect asbestos in a vast variety of building products and materials such as cement products paints, floor tiles, adhesives, Artex, insulation, doors, partitions, and cladding. However, asbestos can be difficult to recognize because the fibers that pose danger are so tiny and light that they could easily float in the air and inhale without being recognized. They don't have distinct smells or odors.

If you suspect that a product could contain asbestos, you can collect one of the samples. This should only be done by a trained professional, because removing asbestos is complex and requires special equipment. Patch the sample using duct tape to avoid the release of fibers and take it to an asbestos analysis laboratory certified by the National Voluntary Laboratory Accreditation Program (NVLAP). A list of accredited laboratories is available on the NVLAP web site.

It's very easy to accidentally damage asbestos and the danger of doing so can be much higher for certain groups of people. These include plumbers, construction workers and electricians, since they are likely to see asbestos-containing materials during renovations and maintenance. Anyone who works in these fields must take an asbestos awareness course to ensure they are aware of the risks and are aware of the right precautions.

Taking Samples

To conduct asbestos testing or an inspection for asbestos testing or inspection, a sample of the material that is suspect is required. This sample can be taken by a qualified asbestos law consultant or by the homeowner, but careful consideration should be taken to minimise the generation of asbestos, http://web011.dmonster.kr/bbs/board.php?bo_table=b0501&wr_id=1764439,-containing dust in the air both when collecting the sample, and during cleaning up afterwards. The person taking the sample will typically need an air vacuum cleaner with HEPA filters, a spray bottle of water and disposable coveralls to provide protection. When they are performing the task they should wear a respirator that is compliant with AS/NZS1716 : 2003 Respiratory protection device. It is best to take samples on the day that isn't windy and asbestos turn off the heating or cooling system. This will help reduce the airborne asbestos particles.

When collecting the sample make sure that the area is sealed off and that no pets or children are 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 a plastic bag and label it as contaminated waste and dispose of it in an approved asbestos disposal facility. Place the bag that is resealable and the sample in a separate plastic bag. Seal it all before declaring it asbestos waste. The area will be cleaned up again and place a plastic drop sheet over it to catch any fibres released.

Asbestos samples are usually collected through a pump and cassette system that is pre-assembled. It is crucial that the cassette does not get overloaded with dust, as this may obscure the fibres of the filter and cause an unintended bias in the outcome. If the sample was taken in an area that has large quantities of non-fibrous dust, it may be necessary to use an air sample with a smaller volume.

While the majority of research focuses on long asbestos fibers but epidemiological studies have revealed that exposure to short asbestos fibers can cause mesothelioma and lung cancer as well. This shows that size is not the only factor that influences the pathogenicity of asbestos fibers. Other parameters such as chemical properties, polarization and dispersion staining, as also the time to etch are also involved.

Identifying Professionals

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

Unaltered asbestos is not a health hazard, but when the materials like flooring, insulation, and shingles are damaged, they could release harmful fibers. This can happen when you are working on a renovation or demolition project, and also when you use your home for normal activities or when the material ages.

If you are planning to remodel your home, you should consult local environmental or health officials to determine if the structure contains asbestos-containing materials. If asbestos is found then it should be examined by an asbestos-certified inspector prior to beginning any work.

If you are planning to renovate an older property, make sure that the contractors you choose to hire have the proper credentials. They must be able to provide an asbestos report and a survey that includes an assessment on the condition of any ACM (asbestos-containing material) and their brittleness. The survey should also include the contractor's intention to remove or leave the ACM intact.

Repairs of minor nature are possible on certain ACM however only a professional with experience in ways to safely handle asbestos should attempt them. Regardless of the type of repair, the area should be kept separate from the other areas of the house, and any equipment or clothing should be stored in plastic bags and labeled with a warning to avoid cross-contamination.

Professionals can seal ACM or cover it to stop the fibers from being released into the air. Sealing (encapsulation) is also referred to as encapsulation, involves treating the material in a way that binds and coats the fibers to ensure they don't become airborne. This can be applied to insulated piping or to cover old shingles.

Professionals can also physically remove ACM from a structure. The materials are then soaked so that they can be cut with a variety of tools without releasing harmful fibers. The material is then placed in airtight, tough containers that are leak-proof.

Removing or repairing Asbestos

Asbestos is resistant to heat and corrosion, which has made it an extremely useful component in thousands of products such as walls, fireproofing materials and auto brakes. But asbestos is also a toxic material that can cause respiratory issues when the fibers are inhaled. Typically, these fibers are trapped in the lungs. They may cause scarring and inflammation of the tissues, which can cause breathing problems and lead to serious health issues.

Asbestos is found in numerous areas of homes, including floor and ceiling tiles roofing shingles exterior siding, cement pipe and asbestos-containing joint compound. Check these areas for water damage, abrasions, or tears. Materials that are slightly damaged can be safe as long as it's not touched or disturbed. However when the material is in need of repair or you are planning to make changes in your home which could cause disturbance to it, you need to speak with an asbestos expert.

These experts can conduct an inspection visually and collect samples. They can also give you information on what changes are required and who qualifies. You should only let these professionals handle asbestos. These professionals are certified in specific products and should only be allowed to correct the problem.

You should also contact your state's local Health Department or Regional Office of the U.S. Environmental Protection Agency to learn about asbestos training programs available in your area. Be aware of firms that claim to be specialists in asbestos removal. These companies are risky because they encourage or perform unneeded removals, which increase the possibility of harmful asbestos fibers being released.

The American Lung Association does NOT endorse these companies. It is essential to conduct a thorough investigation of the company before hiring an asbestos professional to ensure that it is properly insured and certified. You can also request references from past clients, along with evidence of accreditation as well as insurance coverage. You should also check with your state or local health and environmental authorities for the proper guidelines to follow if you are planning to remodel your house.
