How to Identify Asbestos

In the last century, asbestos was used to make a myriad of products stronger and more resistant to fire, and less costly. However, exposure to asbestos-containing airborne fibers could cause lung diseases such as mesothelioma and asbestosis.

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

Identifying Asbestos

Asbestos is a class of naturally occurring minerals that were once used in building materials due to the fact that they are fire-resistant, corrosion resistant and insulation. However, it can create health risks if the microscopic fibers are inhaled. This could lead to illnesses like mesothelioma and asbestosis. These diseases can take years, or even decades, to display their symptoms. They are often mistaken as flu-like symptoms. This is why it's important for people to be aware of how to recognize asbestos.

Tests for medical conditions that detect lung diseases are the most commonly used method to find asbestos. These tests typically include physical examinations or chest Xrays as well as pulmonary function tests. However, asbestos-related diseases aren't identified by these tests alone, as they have to be taken with a thorough patient history that includes the person's home, work and their cultural surroundings.

It's possible to discover asbestos in a diverse variety of building products and materials that include cement products, paints, floor tiles, adhesives, Artex, insulation, doors, partitions and cladding. Asbestos can be difficult to identify because the fibers are so tiny and light. They are able to effortlessly glide throughout the air and then inhale without anyone not even realizing. They also don't create any distinct smells.

You can take a tiny sample if you suspect that the substance you're looking at has asbestos. This should only be done by a qualified professional, because removing asbestos is complex and requires special equipment. Patch the sample with duct tape to prevent 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 has a list of accredited labs.

It is very easy to accidentally cause harm to asbestos, and the risk of doing this is higher for certain categories of people. Plumbers, construction workers, and electricians are at risk of exposure to asbestos during renovations and maintenance. Anyone working in these fields should take an asbestos Settlement awareness course to ensure they are aware of the risks and how to take the right precautions.

Take 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 an asbestos expert or by the homeowner, but it is important to reduce the amount of dust containing asbestos litigation that is airborne both when collecting the sample as well as when cleaning up after. The person who takes the sample will typically need an air vacuum cleaner with HEPA filters along with a spray bottle of water and disposable coveralls to provide protection. They should wear a respirator that conforms to AS/NZS1716.2003 Respiratory safety devices while carrying out the task. It is recommended to carry out the sample collection on a non windy day, and ensure that heating or cooling systems are turned off, since this will reduce the release of any asbestos-containing airborne particles.

When collecting the sample ensure that the area is closed off and that any pets or children are not allowed in. After the sample has been taken and cleaned, clean the tools and equipment with a damp cloth. 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 bag that you re-sealable with the sample in a separate plastic bag, and seal it up before marking it as asbestos waste. Place a plastic dropsheet over the area that needs be cleaned, and then wet it down again. This will capture any fibres released.

Asbestos is typically removed using an already-assembled pump and cassette system. It is essential that the cassette isn't overloaded with dust, because this could obscure the fibres in the filter, causing distortion in the result. If the sample is being taken in an area with high levels of dust that is non-fibrous, a smaller air volume can be employed.

While most testing focuses on long asbestos fibers however, epidemiological studies have revealed that exposure to short asbestos fibres may cause mesothelioma or lung cancer too. This proves that size is not the only factor influencing the pathogenicity of asbestos fibres. Other parameters like chemical properties, polarization and dispersion staining, and etching time are also involved.

Identifying Professionals

Asbestos fibres can become airborne when they are disturbed or spewed out. These microscopic fibers when inhaled, can trigger lung disease. These can cause mesothelioma, asbestosis or other neurological and respiratory problems. The time to develop symptoms can range from 20 to 50 years after exposure.

Unaltered asbestos is not dangerous to health, however when flooring, insulation and shingles are damaged, they could release harmful fibers. This can happen during a renovation or demolition project, or even during normal home usage or aging.

If you are planning to remodel your home, check with local health or environmental officials to determine if the building is made up of asbestos materials. If asbestos is discovered in your home, you must be inspected prior to any work begins by an asbestos inspector who is accredited.

If you are renovating an older house Make sure that any contractors you employ have the necessary qualifications. They should be able to provide an asbestos survey and report, which includes an evaluation of the condition of any asbestos-containing material (ACM) and their friability. The survey should indicate whether or whether the contractor will eliminate the ACM.

Repairs of minor nature are feasible on certain ACM and other ACMs, but only a trained professional who knows the methods for safely handling asbestos should attempt them. No matter what type of repair is done, the area must be sealed from the rest of your home. Any contaminated clothing or equipment should be put in plastic bags and marked with a warning to avoid cross-contamination.

Professionals can cover or seal ACM to prevent it from releasing fibers into the environment. Sealing (encapsulation) involves treating the material with a substance which binds or covers the fibers to prevent them from being airborne. This can be applied to insulated piping or to cover old shingles.

Professionals can also physically remove ACM from a building. The process begins by soaking the materials so that they can be scraped or cut with different tools without releasing the hazardous fibers. Then, they place the materials in durable, leakproof and air-tight containers that are safe for disposal.

Removing or repairing Asbestos

Asbestos is resistant to heat and corrosion This has made it a very useful material in thousands of products such as wallboards, fireproofing insulation and auto brakes. However, asbestos is a toxic material that can cause respiratory problems when fibers are inhaled. These fibers can cause tissue inflammation and scarring of the lungs. This could affect breathing and cause serious health issues.

Asbestos is found in many parts of your home including roof shingles, cement pipes, floor and ceiling tiles, as well as joint compound that is made up of asbestos. Check these areas for water damage or abrasions. If the material is only little damaged, it might be safe to touch or move. However should the material be damaged or you are planning to make changes to your home that might disturb it, you should consult with an asbestos professional.

These professionals can conduct an inspection in person and collect samples. They can also give you advice about what corrections need to be done and who is qualified to carry out them. You should only let these experts handle asbestos. These professionals have been trained in specific asbestos products and should be permitted to correct them.

In addition to consulting with an asbestos specialist who is certified, you should contact your local or state health department or regional office of the U.S. Environmental Protection Agency for more information on asbestos training programs in your area. Be wary of companies that claim to be experts in asbestos removal. These companies are risky because they encourage or perform ineffective removals, which increases the possibility of harmful asbestos fibers being released.

The American Lung Association does NOT endorse these companies. It is crucial to do your research thoroughly before hiring an asbestos expert to ensure that they are properly insured and certified. You can also ask for references from previous clients, and also evidence of accreditation and insurance coverage. It is also recommended that you examine your state's or local environmental and health departments to determine what guidelines must be followed if planning to make any changes within your home.
