How to Identify Asbestos

During the past century, asbestos was used to make a myriad of products stronger and more resistant to fire and less expensive. The exposure to asbestos fibers in the air can trigger lung diseases like asbestosis or mesothelioma.

Some of these diseases have a lengthy latency time. It's hard to spot a problem until it's too long gone.

Identifying Asbestos

Asbestos can be described as a variety of naturally occurring minerals. They were used in building materials for their fire-resistant, corrosion-resistant and insulation properties. However, it could cause health problems when the microscopic fibers are inhaled. This can lead to diseases such as asbestosis and mesothelioma. The symptoms of these diseases do not appear until years, even decades, after the initial exposure. They're often mistaken for flu-like symptoms. This is why it's essential for people to know how to identify asbestos.

The most commonly used method to detect asbestos is by medical tests that check for lung diseases. These tests include physical examinations as well as chest X-rays and lung function tests. These tests are not enough to detect asbestos-related diseases. They should be paired with a comprehensive history of the patient that includes details about the patient's job, home, as well as cultural environment.

It's possible to detect asbestos in a vast range of building materials and materials such as cement products flooring tiles, paints, adhesives, Artex, insulation, doors, partitions, and cladding. However, asbestos can be difficult to recognize because the harmful fibers are tiny and light that they can easily flounder in the air and inhale without being noticed. They also don't create any distinct smells.

If you suspect that a product may contain asbestos, you can take the material as a sample. It is imperative that you only use a professional to remove asbestos settlement, as it's a complex process and requires special equipment. Send the sample to an accredited asbestos analysis lab through the National Voluntary Laboratory Assessment Program (NVLAP). The NVLAP website has a list of accredited laboratories.

Certain groups of people are at a greater risk of accidentally causing damage to asbestos. This includes construction workers, plumbers and electricians, as they are more likely to encounter asbestos-containing items during renovations and maintenance. Anyone working in these fields should take an asbestos awareness course to ensure they are aware of the risks and know how to take the right precautions.

Take Samples

For asbestos testing or inspection, a sample of the material in question is required. This sample can either be taken by an asbestos expert or a homeowner. However it is crucial to ensure that you don't create dust containing asbestos that is airborne during the taking and cleaning. Typically, the person taking the sample must have a HEPA-filtered vacuum cleaner, a water spray bottle, and disposable coveralls to protect themselves. They should also wear a respirator that conforms to AS/NZS1716.2003 Respiratory safety devices when performing the task. It is recommended to conduct the sampling on a calm, non windy day, and ensure that heating or cooling systems are turned off since this will reduce the release of any airborne asbestos particles.

When collecting the sample make sure the area is completely sealed and that pets and children are allowed to access the. The area to be sampled with the help of a damp rag. Then, wipe all tools and equipment that were used after the sample is completed. Place the rag into the bag, label it as asbestos waste, and dispose of it at an asbestos-free facility that is approved by the government. Place the re-sealable bag with the sample inside a different plastic bag, and seal it all before labelling it as asbestos waste. Place a dropsheet of plastic over the area that needs be cleaned and wet it down again. This will collect any fibres released.

Asbestos is usually collected using a pre-assembled pumps and cassette system. It is vital that the cassette isn't filled with dust since this could block the fibres of the filter and asbestos settlement create distortion in the result. If the sample is collected in an area where there are large quantities of nonfibrous dust, it might be necessary to use smaller volumes of air.

The epidemiological studies showed that asbestos fibres of short length can also cause mesothelioma and lung cancer. This indicates that size isn't the only factor influencing the pathogenicity of asbestos fibres. Other parameters like chemical property, polarization dispersion staining, as well as etching time are also involved.

Identifying Professionals

Asbestos fibers can be airborne when they are disturbed, or spread. If inhaled, these tiny fibers can cause lung disease. These microscopic fibers could cause asbestosis or mesothelioma, as well with other neurological and respiratory disorders. The time of onset for many symptoms can vary between 20 and 50 years after exposure.

Asbestos that is not disturbed does not pose any health risks, but when the materials used for insulation, shingles, or flooring are damaged or deteriorate they may release harmful fibers. This can happen during a demolition or renovation project or even in normal home usage or the aging process.

If you're planning to make changes to your home, ask local health or environmental department whether the building has asbestos. If asbestos is found in your home, get it checked before any work is started by an accredited asbestos inspector.

If you're renovating an older house, ensure that any contractors you hire have the appropriate credentials. They must be able conduct an asbestos survey and report that contains an assessment of the state of any asbestos-containing material (ACM) and their ability to be friable. The survey should state whether or the contractor will be removing the ACM.

Minor repairs are possible on some ACM. However only a professional who is trained in the safe handling of asbestos is able to tackle these. No matter what type of repair is completed the area must be protected from the rest of your home. All clothing and equipment should be put into plastic bags and marked with a warning to prevent cross-contamination.

Professionals can seal or cover ACM to stop it from emitting fibers into the environment. Sealing (encapsulation) involves treating the material with a substance that binds or coats 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 from a building. The materials are initially soaked in order to enable them to be cut with various tools without releasing dangerous fibers. The material is then placed in airtight, tough containers that are leakproof.

Removing or repairing Asbestos

Asbestos is invulnerable to corrosion and heat. This makes it a great material for a myriad of products including wallboards insulation, fireproofing and auto brakes. But asbestos is also an irritant that can cause respiratory issues when fibers are inhaled. Typically, these fibers are trapped in the lungs. They could cause tissue inflammation and scarring which can cause breathing problems and lead to serious health issues.

Asbestos can be found in a variety of parts of a house, including roof shingles, cement pipes flooring and ceiling tiles and joint compound made of asbestos. Check these areas for damage or abrasions. Materials that are slightly damaged can be safe if it is not disturbed or touched. If the material needs to be repaired, or you're planning to make changes to your home that could disturb it, then you should consult with an asbestos professional.

These experts can perform an inspection of the visual as well as take samples. They can also offer suggestions on what adjustments are required and who qualifies. It is vital that you let the experts handle your asbestos. Some of these professionals have specialized training in specific products, and they are the only ones who must perform the corrective work on them.

In addition to consulting an asbestos specialist who is certified and contacting your local or state health department or regional office of the U.S. Environmental Protection Agency for information about asbestos training programs in your area. Be wary of companies who claim to be experts in asbestos removal. These companies pose a risk since they promote or perform unnecessary removals, increasing the chance of harmful fibers being released.

The American Lung Association does NOT endorse these companies. It is important to research the company thoroughly before hiring an asbestos expert to ensure that they are properly insured and certified. You can also request references from former clients, as and proof of insurance coverage and accreditation. It is also recommended that you contact your state or local health and environmental agencies to determine what guidelines are required if you're planning to do any remodeling at home.
