How to Identify Asbestos

Over the course of the last century, asbestos was used in thousands of products to make them stronger, more fire-resistant and less costly. Exposure to asbestos fibers in the air can lead to lung disease such as mesothelioma and asbestosis.

Some of these diseases have a long latency period. It's hard to spot the presence of a problem until it is too far gone.

Identifying Asbestos

Asbestos is one of the naturally occurring minerals that were once popular in building materials since they are fire resistant, corrosion resistant and an insulator. Inhaling tiny fibres of asbestos can create health risks. This can lead to the development of diseases such as mesothelioma or asbestosis. The symptoms of these diseases do not show up until years, or years after the initial exposure. They're often mistaken for flu-like symptoms. It is essential that people know how to identify asbestos.

Medical tests that check for lung disease are the most frequent method to identify asbestos. These tests include physical exams, chest X-rays, and lung function tests. These tests aren't sufficient to identify asbestos-related diseases. They should be paired with a complete history of the patient, which includes a person's work, residence, and the cultural context.

Asbestos is found in a wide range of building materials and products, including cement, paints and floor tiles. It is also present in doors, insulation, partitions, cladding, and Artex. However, asbestos can be difficult to recognize because the dangerous fibers are so small and light that they may easily flounder in the air and inhale without being detected. They don't have any distinctive smells, either.

If you suspect a material might contain asbestos, you can take an atom of it. It is crucial that you only use a professional to remove asbestos, as it's complicated and requires special equipment. Patch the sample with duct tape to stop the release of fibers, and take it to an asbestos analysis lab accredited by the National Voluntary Laboratory Accreditation Program (NVLAP). The NVLAP website has an inventory of accredited laboratories.

It's quite easy to cause harm to asbestos, and the risk of doing this can be higher for certain categories of people. Construction workers, plumbers, and electricians are at risk of exposure to asbestos during maintenance and renovations. Anyone working in these fields must take an asbestos awareness course to ensure that they are aware of the dangers and how to take the proper precautions.

Samples to take Samples

For asbestos testing or inspection an asbestos sample of the suspected material is required. This sample could be taken by an asbestos consultant or a homeowner. However it is important to take care not to produce asbestos-containing dust in the air during the taking and cleaning. Typically the person taking the sample should be equipped with an HEPA-filtered vacuum cleaner, a water spray bottle, and disposable coveralls to protect themselves. They should wear a respirator that conforms to AS/NZS1716.2003 Respiratory safety devices while performing the task. It is best to carry out the collection of samples on a non windy day, and ensure that cooling or heating systems are shut off, to reduce the release of any airborne asbestos particles.

When you collect the sample, make sure that the area is sealed off and that no pets or children can be allowed to enter. After the sample has been taken clean all equipment and asbestos tools with a damp cloth. Place the cloth in a plastic bag and label it as contaminated waste, and dispose of it in an asbestos-free disposal facility that is licensed. Place the bag that is resealable and the sample inside a second plastic bag. Secure it all before labeling it as asbestos waste. Clean the area with water to be cleaned a second time and place a plastic drop sheet over it to capture any fibres that escape.

Asbestos is typically filtered using a pre-assembled pump as well as a cassette system. It is essential that the cassette is not overloaded with dust, because this could obscure the fibres of the filter and cause a bias in the result. If the sample is taken in an area with high levels of non-fibrous dust, asbestos a smaller air volume can be utilized.

While most testing focuses on long asbestos fibers however, epidemiological studies have revealed that exposure to short asbestos fibers can cause mesothelioma and lung cancer too. This suggests that size is not the only one of the factors that affect the pathogenicity of asbestos fibers and that other factors such as chemical properties, polarization, dispersion staining and etching times are also involved.

Identifying Professionals

When asbestos fibers are displaced or disturbed they can be airborne. Inhaling these microscopic fibers can cause lung diseases. They can cause mesothelioma, asbestosis or other neurological and respiratory problems. Many symptoms may manifest after 20 to 50 years.

Infrequently disturbed asbestos does not pose an health risk, however when insulation, shingles and flooring become damaged or degraded and release harmful fibers. This can occur when you are working on a renovation or demolition project, or during normal home use or the aging process.

If you're planning to make changes to your home, ask local health or environment officials if the building contains asbestos. If asbestos is discovered in your home, it is recommended to have it checked prior to when any work can begin by an asbestos inspector who is accredited.

If you're renovating an older home, be sure that any contractors you hire possess the right credentials. They should be able to conduct an asbestos survey and report that includes an assessment of the condition of any asbestos-containing material (ACM) and their friability. The survey should also state whether the contractor will remove or leave the ACM intact.

Minor repairs are possible on certain ACM. However, only a professional who is skilled in the safe handling of asbestos is able to tackle these. Whatever repair is completed, the area must be sealed off from the rest of your home. Any clothing or equipment should be put into plastic bags and labeled with a warning in order to prevent cross-contamination.

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

Professionals can also physically remove ACM from a structure. The process begins by soaking the materials so they can be cut or scraped using various tools without releasing the hazardous fibers. The materials are then put in airtight, durable containers that are leakproof.

Removing or fixing Asbestos

Asbestos is impervious to corrosion and heat. This makes it an ideal material for a variety of products such as wallboard, fireproofing insulation, and auto brakes. But asbestos is also a toxic material that could cause respiratory issues when fibers are inhaled. These fibers can cause tissue inflammation and scarring of the lungs. This can affect breathing and lead to serious health problems.

Asbestos can be found in numerous areas of a home such as roof shingles, cement pipes and floor and ceiling tiles and joint compound that is made up of asbestos legal. Examine these areas for water damage, abrasions, or tears. If the material is only slightly damaged, it could be safe to touch or even disturb. However should the material be in need of repair or you plan to make changes to your home that might disturb it, you need to consult an asbestos law professional.

These professionals can perform an inspection by visuals as well as take samples. They can also provide guidance on the corrective measures required and who is certified. It is important that you let these professionals handle your asbestos. Some of them are trained in specific products, and only they are qualified to perform remedial work on them.

It is also recommended to 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 area. Beware of firms that claim to have a specialization in asbestos removal. These firms can be hazardous because they promote unnecessary removals or conduct them improperly which increases the risk of the release of harmful fibers.

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 certified and insured. You can also request references from former clients as and proof of accreditation and insurance coverage. You should also inquire with your state or local health and environmental agency for the proper guidelines to follow if you are planning to remodel your house.
