How to Identify Asbestos

In the past century asbestos was utilized in thousands of products to make them more durable, less prone to fire and less costly. Exposure to asbestos lawyer fibers in the air can cause lung diseases such as mesothelioma or asbestosis.

Certain of these diseases could be chronically latent. This makes it difficult for people to identify an issue before it's late.

Identifying Asbestos

Asbestos is a group of naturally occurring minerals that were once popular in building materials because they are fireproof, corrosion resistant and insulate. Inhaling the tiny fibres could be harmful to health. This can lead to diseases such as asbestosis and mesothelioma. The symptoms of these diseases don't appear until years, even decades after the initial exposure. They're often confused with flu-like symptoms. This is the reason it's so important for people to know how to recognize asbestos.

Tests for medical conditions that detect lung disease are the most popular method to determine if you have asbestos. These tests usually include physical examinations, chest X-rays and lung function tests. However, asbestos-related ailments can't be diagnosed using these tests on their own, since they need to be combined with a thorough history of the patient which includes a thorough examination of a person's work, home and social environment.

It's possible to discover asbestos in a diverse range of building products and materials such as cement, paints, floor tiles, adhesives, Artex, insulation, doors, partitions, and cladding. Asbestos is difficult to identify because the fibers are so small and light. They are able to easily glide through the air, and inhale without anyone noticing. They don't have distinctive smells, either.

If you think a substance might contain asbestos, you can collect one of the samples. This should only be performed by a certified professional as removing asbestos is very complicated and requires specialized equipment. Send the sample to an accredited Asbestos settlement analysis lab through the National Voluntary Laboratory Assessment Program (NVLAP). A list of laboratories is available on the NVLAP web site.

Certain groups of people are more at risk of accidentally disturbing asbestos. Plumbers, construction workers and electricians are at risk of exposure to asbestos in maintenance and renovations. Any person who works in these fields should attend an asbestos awareness course to ensure they are aware of the risks and know how to take the proper precautions.

Take Samples

A sample of the suspected material is required for asbestos testing or inspection. This sample can be taken by a qualified asbestos consultant or by the homeowner, however care must be taken to limit the formation of asbestos-containing dust in the air both when collecting the sample, and during cleaning up after. The person taking the sample is likely to require an air vacuum cleaner that is HEPA-filtered, a spray bottle of water and disposable coveralls to provide protection. They must wear a respirator that is compliant with AS/NZS1716:2003 Respiratory protection devices while performing the task. It is recommended to take samples on the day that isn't windy and shut off the heating or cooling system. This will reduce the airborne asbestos particles.

If you are collecting the sample, make sure that the area is closed off and that pets or children aren't allowed in. After the sample has been taken clean all equipment and tools using a damp cloth. Place the rag in a plastic bag, mark it as asbestos waste, and dispose of it at an approved asbestos disposal facility. Place the resealable bag along with the sample into a second plastic bag. Seal it all together before declaring it asbestos waste. Place a plastic dropsheet over the area that needs be cleaned. Then, wet it down again. This will collect any fibres that escape.

Asbestos can be filtered with a pre-assembled pumps and cassette system. It is important that the cassette does not get overloaded with dust, because this could obscure the fibres in the filter and cause a bias in the result. If the sample is being taken from an area that has high amounts of dust that is not fibrous a smaller volume of air can be used.

The epidemiological research found that asbestos fibres that are short can also trigger mesothelioma or lung cancer. This indicates that size is not the only one of the factors influencing asbestos fibers' pathogenicity and that other factors such as chemical properties such as dispersion staining, dispersion polarization and etching times are also involved.

Identifying Professionals

When asbestos fibers are displaced or disturbed they can be airborne. These microscopic fibers, once inhaled, may cause lung disease. They could cause mesothelioma, asbestosis or other neurological and respiratory problems. The latency period for many symptoms can be anywhere from 20 to 50 years after exposure.

Asbestos that is not disturbed does not pose the risk of health hazards, but when the materials used for insulation, shingles, and flooring become damaged or degraded they could release harmful fibers. This can occur in the course of a renovation or demolition project, as well as in normal home use or as the house ages.

If you are planning to remodel your home, consult local officials from the environmental or health department to determine if your home contains asbestos-containing materials. If asbestos is discovered in your home, it is recommended to get it checked before any work begins by an accredited asbestos inspector.

When renovating an older home be sure that any contractors you hire have proper qualifications. They should be able supply an asbestos report and survey that contains an assessment of the condition of any ACM (asbestos case-containing material) and their friability. The survey should also indicate whether the contractor will take away or leave the ACM intact.

Minor repairs might be feasible on certain ACM and other ACMs, but only a trained professional who knows the techniques for handling asbestos safely should attempt these repairs. No matter what kind of repair you make, the area must be sealed off from the rest of your home. All clothing and equipment should be placed into plastic bags and labeled with a warning to prevent cross-contamination.

Professionals can cover or seal ACM to stop it from emitting fibers into the environment. Sealing (encapsulation) is also referred to as encapsulation, is the process of treating the material in a manner that binds and seals the fibers, ensuring that they don't become airborne. This can be done on insulated piping, or to cover old shingles.

Professionals can also physically remove ACM. This process begins by wetting the materials to allow them to be scraped or cut with many tools without releasing the dangerous fibers. Then they place the material in sturdy, leakproof and air-tight containers that are safe for disposal.

Removing or fixing Asbestos

Asbestos is invulnerable to heat and corrosion. This makes it a useful material for thousands of products including wallboards as well as fireproofing insulation and auto brakes. Asbestos is a poisonous substance that can cause respiratory issues when fibers are breathed in. These fibers can cause tissue inflammation and scarring in the lungs. This can impact breathing and cause serious health problems.

Asbestos can be found in numerous areas of homes, including ceiling and floor tiles roofing shingles exterior siding, cement pipe and asbestos-containing joint compound. It's important to check these areas frequently for tears, abrasions, or water damage. Slightly damaged material may be safe if not touched or disturbed. However when the material is damaged or you are planning to make changes in your home that could affect it, seek out an asbestos expert.

These experts can conduct a visual inspection and take samples. They can also provide guidance on the corrective measures required and who qualifies. It is best to let professionals handle asbestos. Some of these professionals have specialized training in specific products, and only they are qualified to perform remedial work on them.

You can also contact your local or State Health Department or Regional Office of the U.S. Environmental Protection Agency to find out about asbestos training programs offered in your area. Beware of companies that claim to have a specialization in asbestos removal. These companies can be risky because they encourage unnecessary removals or make them in a way that isn't properly done and increase the risk of release of harmful fibers.

The American Lung Association does NOT endorse these companies. Before you hire an asbestos professional it is essential to investigate the company thoroughly to ensure that it's certified and insured. You can also request 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 agencies to determine the best steps to follow if are planning to renovate your home.
