How to Identify Asbestos

In the past century, asbestos was used to make a myriad of products stronger and more resistant to fire, and cheaper. Exposure to asbestos fibers in the air can cause lung diseases such as mesothelioma or asbestosis.

Some of these diseases have a long latency period. It is difficult to detect 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 since they are fire retardant, corrosion resistant and insulate. It could, however, cause health problems when the microscopic fibers inhaled. This often causes diseases like asbestosis and mesothelioma. The symptoms of these illnesses don't manifest until years, if not decades, after the initial exposure and are often confused with flu-like symptoms. It is essential that people know how to identify asbestos.

The most effective method to identify asbestos is through medical tests that look for lung disease. These tests typically include physical examinations as well as chest X-rays, and tests for pulmonary function. These tests aren't enough to diagnose asbestos-related diseases. They should be paired with a comprehensive history of the patient that includes the person's work, home, and the cultural context.

Asbestos can be found in a variety of building materials and products, including cement, paints and floor tiles. It is also found in insulation, doors, partitions, cladding, and Artex. However, asbestos can be difficult to recognize since the fibers that pose danger are so small and light that they may easily flounder in the air and inhale without being noticed. They don't possess any distinct smells either.

If you suspect that a product could contain asbestos, you can collect the material as a sample. This should be done by a certified professional as removing asbestos is very complex 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 an inventory of accredited laboratories.

Certain groups of people are at a greater danger of accidentally touching asbestos. These include construction workers, plumbers and electricians, since they are more likely to encounter asbestos-containing items during renovations and maintenance. It's a good idea for all workers in these fields to complete an asbestos Settlement awareness training course so that they understand the dangers and are able to be aware of the appropriate precautions to take.

Take Samples

For asbestos testing or inspection, a sample from the material that is suspect is required. This sample could be taken by an asbestos expert or a homeowner. However it is essential to ensure that you do not produce asbestos-containing dust in the air during the taking and cleaning. The person who takes the sample will normally require a HEPA-filtered air vacuum cleaner and a spray bottle of water and disposable coveralls as protection. They should wear a respirator that conforms to AS/NZS1716.2003 Respiratory protective equipment while carrying out the task. It is best to conduct the sample collection on a non windy day, and ensure that cooling or heating systems are off, as this will minimise the release of any airborne asbestos particles.

When you collect the sample, make sure the area is completely sealed off and that pets and children are allowed to enter. Clean the area to be sampled with an abrasive rag, then wipe all tools and equipment used once the sampling has been completed. Place the rag in the bag, label it as asbestos waste and dispose of it at an approved asbestos disposal facility. Place the bag that you re-sealable with the sample inside a second plastic bag, and seal it all up before declaring it asbestos waste. Place a dropsheet made of plastic over the area that needs to be cleaned. Then, wet it down once more. This will capture any fibres that are released.

Asbestos samples are usually collected by using a pump or cassette system that is pre-assembled. It is vital that the cassette isn't overloaded with dust, as this can obscure the fibres of the filter and create an unintended bias in the outcome. If the sample is located in an area that has significant levels of nonfibrous dust may be necessary to utilize less air.

The epidemiological studies showed that asbestos fibres that are short could also cause mesothelioma or lung cancer. This shows that size is not the only factor that influences the pathogenicity asbestos fibres. Other parameters like chemical properties, polarization and dispersion staining, as also the time to etch are also involved.

Identifying Professionals

When asbestos fibers are displaced or disturbed they can airborne. Inhaling these microscopic fibers can cause lung diseases. These microscopic fibers can cause mesothelioma or asbestosis as well as other respiratory and neurological conditions. Many symptoms may manifest within 20 to 50 years.

Infrequently disturbed asbestos does not pose an health risk, however when materials like insulation, shingles and flooring become damaged or degraded they could release harmful fibers. This can occur during a renovation or demolition project, as well as during normal home use or aging.

If you plan on remodeling your home, consult local environmental or health officials to determine if the structure contains asbestos materials. If asbestos is discovered in your home, you must have it checked prior to when any work begins by an asbestos inspector who is accredited.

When you're renovating an older home be sure that any contractors you choose to hire have the required credentials. They must be able to provide an asbestos report and survey that includes an assessment on the condition of any ACM (asbestos-containing material) and their friability. The survey should also specify whether the contractor will remove or leave the ACM intact.

Minor repairs might be possible on some ACM repairs, but only a professional with experience in techniques for handling asbestos safely should attempt these repairs. Whatever repair you make it is essential that the area be protected from the rest of your home. All clothing and equipment should be put into plastic bags and labeled with a warning to avoid cross-contamination.

Professionals can seal ACM or cover it to keep fibers from getting released into the environment. Sealing (encapsulation), also known as encapsulation, involves treating the material in a manner that binds and seals the fibers so they don't become airborne. This can be done on insulated pipes, or to cover old shingles.

Professionals are also able to physically remove ACM. This is accomplished by wetting the materials so that they can be cut or scraped using many tools without releasing dangerous fibers. Then, they place the materials in durable, leak-proof air-tight containers to ensure safe disposal.

Repairing or removing Asbestos

Asbestos is impervious to corrosion and heat. This makes it a great material for a variety of products such as wallboard insulation, fireproofing and auto brakes. But asbestos is also an irritant that can cause respiratory issues when the fibers are inhaled. In most cases, these fibers end up stuck in the lungs, and can lead to scarring and inflammation of the tissues, which can cause breathing problems and cause serious health problems.

Asbestos can be found in a variety of areas of a house which includes roof shingles cement pipes as well as floor and ceiling tiles and joint compound that is made up of asbestos attorney. It is essential to examine these areas on a regular basis for damage, tears, or asbestos settlement damage. If the material is little damaged, it might be safe to touch or move. However should the material be damaged or you are planning to make changes in your home that could affect it, you should consult an asbestos professional.

These experts can conduct an inspection of the visuals and take samples. They can also provide guidance on the corrective measures needed and who is qualified. Only professionals handle asbestos. Certain of these professionals have specialized training in specific products, and they're the only ones who should do corrective work on them.

You can also contact your state's local Health Department or Regional Office of the U.S. Environmental Protection Agency to learn about asbestos training programs offered in your area. Be aware of firms that claim to have a specialization in asbestos removal. These companies pose a risk because they encourage or perform ineffective removals, which increases the chance of harmful fibers being released.

The American Lung Association does NOT endorse these companies. Before hiring an asbestos expert it is essential to conduct a thorough investigation of the company to ensure it's certified and insured. You can also request references from previous clients as well as proofs of insurance and accreditation. You should also check with your state or local health and environmental authorities to determine the best procedures to follow if you plan to remodel your home.
