How to Identify Asbestos

In the last century asbestos was utilized in a myriad of products to make them stronger, more resistant to fire and less costly. Exposure to asbestos fibers within the air can lead to lung diseases such as mesothelioma and asbestosis.

Some of these diseases can be chronically latent. This means it is difficult for people to identify a problem before it's too late.

Identifying Asbestos

Asbestos is one of the naturally occurring minerals that were used in building materials due to the fact that they are fire resistant and corrosion resistant, as well as insulation. Inhaling the microscopic fibres can cause health hazards. This can lead to diseases such as asbestosis and mesothelioma. Symptoms of these illnesses don't manifest until years, if not decades after initial exposure and are often misinterpreted as flu-like symptoms. This is why it's essential for people to know how to recognize asbestos.

The most common way to detect asbestos is via medical tests that check for lung diseases. These tests usually consist of physical examinations as well as chest X-rays, and tests for pulmonary function. However, asbestos-related illnesses can't be diagnosed with these tests on their own, since they need to be combined with a thorough history of the patient that includes the person's home, work and social environment.

It is possible to find asbestos in a wide range of building materials and materials such as cement products floor tiles, paints, adhesives, Artex, insulation, doors, partitions, and cladding. Asbestos can be difficult to identify because the fibers are tiny and light. They are able to effortlessly glide through the air and inhale without anyone even noticing. They also don't create any distinct smells.

If you suspect a material might contain asbestos, you can take a sample of it. This should be done by a qualified professional, because the process of removing asbestos is complex and requires specialized equipment. Patch the sample with duct tape to prevent the release of fibers, and take it to an asbestos analysis lab accredited by the National Voluntary Laboratory Accreditation Program (NVLAP). The NVLAP website provides an inventory of accredited laboratories.

It is very easy to accidentally damage asbestos and the risk of doing so can be much higher for certain groups of people. Plumbers, construction workers and electricians are all at risk of exposure to asbestos during maintenance and renovations. Everyone who works in these areas should complete an asbestos awareness course to ensure they are aware of the risks and are aware of the proper precautions.

Take Samples

To conduct asbestos testing or an inspection an asbestos sample of the suspect material is needed. This sample could be taken by an asbestos consultant or a homeowner. However it is important to be careful not to generate airborne asbestos-containing dust during the taking and cleaning. The person who collects the sample should carry a HEPA-filtered vacuum cleaner a water spray bottle and disposable coveralls to protect themselves. They should wear a respirator that complies with AS/NZS1716:2003 Respiratory protective devices when performing the task. It is recommended to take samples on an occasion that isn't windy and shut off the heating or cooling system. This will reduce the release of airborne asbestos particles.

When you collect the sample, ensure that the area is fully sealed off and that pets or children are not permitted in. The area to be sampled with the help of a damp rag. Then, clean all equipment and tools that were used during the sampling process after it is completed. Place the damp rag in a bag and label it as contaminated waste, and dispose of it at an asbestos disposal facility that is approved. Place the resealable bag along with the sample inside a second plastic bag. Seal it all together before declaring it asbestos waste. Make sure to rinse the area to be cleaned a second time and place a drop sheet over it, to catch any fibres released.

Asbestos Settlement samples are usually collected by using a pump or cassette system that is pre-assembled. It is crucial to ensure that the cassette doesn't be suffocated with dust. This could obscure fibers and distort results. If the sample is collected in an area with large quantities of non-fibrous dust, it may be necessary to utilize less air.

The epidemiological studies found that asbestos fibres that are short can also cause mesothelioma and lung cancer. This shows that size isn't the only factor in determining asbestos fibers' pathogenicity. Other factors like chemical properties, polarization and dispersion staining as well as etching time are also involved.

Identifying Professionals

Asbestos fibres can become airborne when they are disturbed or spread. These microscopic fibers when inhaled, can trigger lung diseases. They could cause mesothelioma or asbestosis, as well as other respiratory and neurological problems. Many symptoms may manifest in the 20 to 50 years following.

Unaffected asbestos is not a health risk, but when the insulation, shingles and flooring are damaged or deteriorate they may release harmful fibers. This could happen when you are working on a renovation or demolition project, or when you use your home for normal activities or the aging process.

If you're planning to renovate your home, inquire with your local health or environmental department if the building contains asbestos. If asbestos is found in your home, get it checked before any work can begin by an asbestos inspector who is accredited.

If you are renovating an older house, ensure that the contractors you choose to hire have the proper credentials. They should be able provide an asbestos survey and report that includes an assessment of the condition of any asbestos-containing material (ACM) and their friability. The survey should state whether or not the contractor will remove the ACM.

Minor repairs are feasible on certain ACM. However, only a professional who is skilled in the safe handling of asbestos should attempt these. Whatever the type of repair, the area must be kept separate from the rest of the home and any contaminated equipment or clothing should be placed in plastic baggies and labeled with a warning in order to prevent cross-contamination.

Professionals can seal ACM or cover it to prevent fibers from getting released into the environment. Sealing (encapsulation) involves treating the material with a chemical that binds or coats fibers to keep 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 in order that they can be cut or scraped with various tools without releasing the hazardous fibers. Then they place the material in durable, leakproof air-tight containers to ensure safe disposal.

Repairing or Removing Asbestos

Asbestos is abrasive to heat and corrosion which makes it a very useful material in thousands of products such as wallboards, fireproofing insulation and auto brakes. However, asbestos compensation is a toxic material that can cause respiratory issues when fibers are inhaled. These fibers can cause tissue inflammation and scarring in the lungs. This can be detrimental to breathing and can cause serious health issues.

Asbestos can be found in numerous parts of your home including roof shingles, cement pipes flooring and ceiling tiles and joint compound that is made up of asbestos. It is important to inspect these areas regularly for tears, abrasions, or water damage. If the material is slightly damaged, it may be safe to touch it or disturb it. If the material has to be repaired or replaced, or you are planning to make changes to your home that could affect it, you must seek advice from an asbestos professional.

These professionals can conduct a visual inspection and take samples. They can also provide suggestions on what adjustments are needed and who is qualified. It is recommended that only these experts handle asbestos. These professionals are educated in specific products and should be allowed to correct them.

It is also recommended to contact your local or State Health Department or Regional Office of the U.S. Environmental Protection Agency to find out about asbestos training programs available in your region. Beware of firms who claim to be experts in asbestos removal. These firms could be dangerous since they encourage removals that are not needed or perform them improperly which increases the risk of release of harmful asbestos fibers.

The American Lung Association does NOT endorse these companies. Before hiring an asbestos specialist it is crucial to conduct a thorough investigation of the company to ensure that it's certified and insured. You can also request references from past clients, as well as proof of insurance coverage and accreditation. It is also recommended to check with your local or state health and environmental agency for the correct steps to follow if plan to remodel your home.
