How to Identify Asbestos

In the last century, asbestos was used in thousands of products to make them more durable, fire resistant and less costly. Exposure to asbestos fibers in the air can cause lung diseases like asbestosis or mesothelioma.

Certain diseases may be chronically latent. This makes it difficult to recognize the problem before it's too late.

Identifying Asbestos

Asbestos is one of the naturally occurring minerals that were previously used in building materials because they are fire retardant and corrosion resistant, as well as insulate. However, it can pose health risks when the microscopic fibers are inhaled. This can lead to diseases like mesothelioma and asbestosis. These illnesses can take years, or even decades, to display their symptoms. They are often misinterpreted as flu-like symptoms. This is the reason it's so important for people to know how to recognize asbestos.

The most popular method to detect asbestos is via medical tests that look for lung disease. These tests typically include physical examinations, chest X-rays and tests for pulmonary function. These tests aren't enough to determine the presence of asbestos-related illnesses. They must be combined with a comprehensive history of the patient which includes information about a person's work, residence, and the cultural context.

It's possible to find asbestos in a wide variety of building products and materials that include cement products 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 breathe without anyone being aware. They don't also emit distinct smells.

If you think a substance could be contaminated with asbestos, you can collect the material as a sample. This should only be done by a qualified professional, since removing asbestos is extremely complex and requires specialized equipment. Patch the sample using duct tape to avoid the release of fibers and send it to an asbestos analysis laboratory that is accredited by the National Voluntary Laboratory Accreditation Program (NVLAP). A list of accredited laboratories can be found on the NVLAP website.

It's easy to accidentally alter the asbestos in a way and the risk of doing so is higher for certain categories of people. These include plumbers, construction workers, and electricians, since they are more likely to encounter asbestos-containing materials in maintenance and renovations. It's recommended for anyone who works in these fields to take an asbestos awareness course to make sure they are aware of the dangers and make the right precautions.

Take Samples

A sample of the suspected material is required to conduct 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 and while cleaning up afterwards. The person who is taking the sample is likely to require an air vacuum cleaner with HEPA filters as well as a spray bottle filled with water, and disposable covers for protection. They should also wear a respirator which complies with AS/NZS1716:2003 Respiratory protective devices while carrying out the task. It is recommended to take samples on the day that isn't windy, and then shut off the cooling or heating system. This will limit the airborne asbestos particles.

When collecting the sample make sure that the area is sealed off and that pets and children are allowed to get into the. After the sample has been collected then clean up all tools and equipment with a damp cloth. Place the rag into the bag, asbestos label it as asbestos attorney waste, and dispose of it in an approved asbestos disposal facility. Place the resealable bag and the sample in a second plastic bag. Seal it all together before labeling it as asbestos waste. Place a plastic dropsheet over the area that must be cleaned. Then, wet it down again. This will collect any fibres released.

Asbestos can be filtered with a pre-assembled pump and cassette system. It is important that the cassette is not filled with dust because this could obscure the fibres on the filter and cause an unintended bias in the outcome. If the sample is taken in an area with high levels of non-fibrous dust, it may be necessary to use less air.

The epidemiological studies revealed that asbestos fibres that are short could also cause mesothelioma or lung cancer. This indicates that size is not the only one of the factors that affect the pathogenicity of asbestos fibres and that other parameters such as chemical properties such as dispersion staining, dispersion polarization and etching times are also involved.

Identifying Professionals

Asbestos fibers may become airborne when they are disturbed or spread. When inhaled, these tiny fibers can cause lung disease. These microscopic fibers can trigger asbestosis or mesothelioma as well as other neurological and respiratory diseases. The time to develop symptoms can be anywhere 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 could happen during a renovation or demolition project, and also in normal use of the home or as the house ages.

If you are planning on transforming your home, make sure you check with local health or environmental officials to determine if your home contains asbestos-containing materials. If any asbestos-containing material is discovered and inspected, you must have it checked by an accredited asbestos inspector prior to beginning any work.

When renovating an older home, make sure any contractors you hire have necessary qualifications. They should be able supply an asbestos report and survey that contains an assessment of the condition of any ACM (asbestos-containing material) and their brittleness. The survey should also specify whether the contractor plans to remove or leave the ACM intact.

Minor repairs are possible with certain ACM however only a professional trained in methods for safely handling asbestos should attempt them. Whatever the kind of repair, the site should be sealed off from the rest of the home and any equipment or clothing should be placed in plastic bags and marked with a warning so as to avoid cross-contamination.

Professionals can seal ACM or cover it to prevent fibers from being released into the atmosphere. Sealing (encapsulation) involves treating the material with a chemical which binds or covers 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. The materials are initially soaked to allow them to be cut using a variety of tools without releasing harmful fibers. The materials are then placed in airtight, sturdy containers that are leakproof.

Removing or replacing Asbestos

Asbestos is invulnerable to heat and corrosion, which has made it an extremely useful material for many different products like wallboard materials, fireproofing insulation and auto brakes. But asbestos is also a toxic material that could cause respiratory issues when fibers are inhaled. These fibers can cause tissue inflammation and scarring in the lungs. This could affect breathing and lead to serious health issues.

Asbestos can be found in numerous parts of a house, including roof shingles, cement pipes and floor and ceiling tiles and joint compound containing asbestos. It is important to inspect these areas on a regular basis for damage, tears, or damage. Slightly damaged material may be safe if not disturbed or touched. If the material must be repaired, or you're planning to make changes to your home that could affect it, then you should consult an asbestos expert.

They can conduct an inspection in person and collect samples. They can also offer suggestions on what adjustments are required and who's qualified. It is recommended that only these experts handle asbestos. They have been trained in specific asbestos products and should be allowed to correct them.

In addition, to talking with an asbestos expert who is trained and contacting your state or local health department or regional office of the U.S. Environmental Protection Agency for information about asbestos-related training programs in your area. Also, be aware that there are companies which falsely claim they specialize in asbestos removal. These firms pose a threat since they promote 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 the company is properly insured and certified. You can ask for references from previous clients as and proof of insurance and accreditation. It is also recommended that you check with your state or local environmental and health departments to find out what procedures must be followed if planning to make any changes within your home.
