How to Identify Asbestos

During the last century asbestos was utilized in a myriad of products to make them more durable, less prone to fire and less costly. But exposure to airborne asbestos fibers can lead to lung diseases such as asbestosis and mesothelioma.

Some of these diseases have a lengthy latency time. This makes it difficult for people to spot an issue before it's late.

Asbestos Identification

Asbestos is a class of naturally occurring minerals that were used in building materials due to the fact that they are fire-resistant, corrosion resistant and an insulator. It could, however, pose health risks when the microscopic fibers are inhaled. It is common for them to cause diseases like asbestosis and mesothelioma. Symptoms of these illnesses don't manifest until years, if not decades, after the initial exposure. They're often confused with flu-like symptoms. It's essential to know how to identify the asbestos.

Medical tests that check for lung disease are the most frequent method to determine if you have asbestos. These tests include physical exams or chest X-rays as well as lung function tests. However, asbestos-related illnesses aren't diagnosed by using these tests alone, as they have to be taken with a thorough medical history that examines a person's home, work and the cultural context.

Asbestos is found in a wide range of building products and materials, including cement, paints and floor tiles. It is also present in doors, insulation and partitions, cladding and Artex. Asbestos can be difficult to spot because the fibers are tiny and light. They can effortlessly float through the air, and inhale without anyone noticing. They don't possess any distinct smells either.

You can take a small sample if you suspect the material you are looking at contains asbestos. It is imperative that you only use a professional to remove asbestos, as it's a complex process and requires special equipment. Patch the sample with duct tape to stop the release of fibers and send it to an asbestos analysis laboratory that is accredited by the National Voluntary Laboratory Accreditation Program (NVLAP). The NVLAP website provides an inventory of accredited laboratories.

Certain groups of people are at greater danger of accidentally touching asbestos. This includes construction workers, plumbers and electricians, since they are most likely to come across asbestos-containing products during renovations and maintenance. It's recommended for all workers in these areas to complete an asbestos awareness course to make sure they are aware of the risks and can use 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 professional asbestos consultant or by the homeowner, however caution must be taken to reduce the amount of asbestos-containing dust in the air both during the collection of the sample as well as when cleaning up after. Typically, the person who is taking the sample should be equipped with a vacuum cleaner that is HEPA-filtered, a water spray bottle, and disposable coveralls to protect themselves. When they are performing the task they should wear a respirator compliant with AS/NZS1716 : 2003 Respiratory protection device. It is recommended to conduct the collection of samples on a non windy day, and ensure that heating or cooling systems are turned off as this will minimise the release of any airborne asbestos law particles.

If you are collecting the sample, ensure that the area is closed off and that children or pets are not allowed in. Wet down the area to be sampled using a damp rag, and clean any tools and equipment used once the sampling 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 resealable bag and the sample inside a second plastic bag. Seal it all before marking it as asbestos waste. Place a dropsheet made of plastic over the area to be cleaned and then wet it down once more. This will capture any fibres that are released.

Asbestos is typically filtered using a pre-assembled pump as well as a cassette system. It is important that the cassette is not overloaded with dust, as this may obscure the fibres of the filter and cause an imbalance in the results. If the sample is taken from an area that has high levels of non-fibrous dust, a smaller air volume can be employed.

While the majority of research focuses on asbestos fibers that are long, the epidemiological studies have found that exposure to short asbestos fibers can cause mesothelioma and lung cancer as well. This shows that size isn't the only factor in determining the pathogenicity of asbestos fibres. Other parameters, such as chemical properties, polarization and dispersion staining, as also the time required to etch are also a factor.

Identifying Professionals

Asbestos fibers can become airborne when they are disturbed, or spread. These microscopic fibers, once inhaled, can trigger lung disease. They can cause mesothelioma and asbestosis as well as other neurological and respiratory ailments. Many symptoms can appear 20 to 50 years later.

Undisturbed asbestos does not pose the risk of health hazards, but when materials like insulation, shingles, and flooring are damaged or deteriorate they may release harmful fibers. This can happen when you are working on a renovation or demolition project, as well as in normal use of the home or the aging process.

If you're planning to renovate your home, ask local health or environmental department to determine if the structure is contaminated with asbestos. If asbestos is discovered in your home, have it checked prior to when any work is started by an accredited asbestos inspector.

When renovating an older home ensure that the contractors you employ have the necessary credentials. They should be able supply an asbestos report and survey that contains an assessment on the condition of any ACM (asbestos-containing material) and their brittleness. The survey should also specify the contractor's intention to remove or leave the ACM intact.

Minor repairs might be feasible on certain ACM, asbestos settlement but only a certified professional who has been trained in ways to safely handle Asbestos Settlement should attempt these repairs. Regardless of the type of repair, the area must be kept separate from the other areas of the house, and any equipment or clothing should be placed in plastic bags and marked with a warning in order to prevent cross-contamination.

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

Professionals can also physically remove ACM from a building. The materials are first wetted to allow them to be cut with a variety of tools without releasing dangerous fibers. The material is then placed in airtight and durable containers that are leakproof.

Repairing or removing Asbestos

Asbestos is invulnerable to heat and corrosion. This makes it a suitable product for thousands of uses, including wallboard insulation, fireproofing and auto brakes. However, asbestos law is a toxic material that can cause respiratory issues when the fibers are inhaled. In most cases, these fibers end up trapped in the lungs. They may cause scarring and inflammation of the tissues, which can cause breathing problems and cause serious health issues.

Asbestos can be found in numerous parts of a house such as roof shingles, cement pipes as well as floor and ceiling tiles, and joint compound that contains asbestos. Be sure to check these areas for water damage, abrasions, or tears. Material that is slightly damaged may be safe if not manipulated or smashed. If the material requires to be repaired or replaced, or you are planning to make changes to your home that could disturb it, then you should seek advice from an asbestos professional.

These experts can conduct an inspection visually and collect samples. They can also provide suggestions on what adjustments are needed and who is qualified. It is important to have only these professionals manage your asbestos. These professionals are certified in specific products and should be permitted to correct them.

In addition to consulting a trained asbestos professional It is also recommended to contact your state or local health department or regional office of the U.S. Environmental Protection Agency for more information on asbestos training programs in your area. Also, be aware of companies who falsely claim to specialize in asbestos removal. These firms are dangerous as they encourage or conduct unneeded removals, which increase the chance of harmful fibers being released.

The American Lung Association does not endorse these companies. Before you hire an asbestos professional it is crucial to conduct a thorough investigation of the company to ensure that it's accredited and insured. You can also request references from former clients, as and proof of insurance coverage and accreditation. It is also recommended that you examine your state's or local health and environmental authorities to determine the procedure that should be followed if you're planning to undertake any renovations within your home.
