How to Identify Asbestos

In the last century asbestos was utilized in thousands of products to make them stronger, more resistant to fire and less costly. However, exposure to airborne asbestos fibers can lead to lung diseases like mesothelioma or asbestosis.

Certain diseases have a lengthy latency time. It is difficult to detect a problem until it's too long gone.

Asbestos Identification

Asbestos is a class of naturally occurring minerals that were used in building materials since they are fire resistant and corrosion resistant, as well as insulation. However, it could cause health problems when the microscopic fibers are inhaled. This is often the cause of diseases like asbestosis and mesothelioma. These illnesses can take years or even decades to display their symptoms. They are often interpreted as flu-like symptoms. This is why it's essential for people to be aware of how to identify asbestos.

Medical tests that test for lung disease are the most commonly used method to determine if you have asbestos. These tests include a physical exam as well as chest X-rays and lung function tests. These tests are not enough to determine the presence of asbestos-related illnesses. They must be combined with a comprehensive history of the patient, which includes a person's job, home, and the environment in which they live.

Asbestos is found in a myriad of building products and materials, such as cement, paints and floor tiles. It can also be found in insulation, doors partitions, cladding and Artex. However, asbestos can be difficult to recognize because the fibers that pose danger are so small and light that they can easily float in the air and then be breathed in without being recognized. They also don't emit any distinctive smells.

If you suspect that a product might contain asbestos, you can take an atom of it. This should only be performed by a certified professional because removing asbestos is complicated and requires the use of specialized equipment. Send the sample to an accredited asbestos analysis laboratory through the National Voluntary Laboratory Assessment Program (NVLAP). A list of accredited laboratories is available on the NVLAP website.

It's quite easy to cause harm to asbestos and the risk of doing so is much higher for certain groups of people. This includes plumbers, construction workers and electricians, as they are most likely to come across asbestos-containing materials during maintenance and renovations. Anyone who works in these fields should attend an asbestos law awareness course to ensure that they are aware of the risks and how to take the necessary precautions.

Take Samples

A sample of the suspected material is required for asbestos testing or asbestos inspection. The sample can be collected by a qualified asbestos consultant or by the homeowner, however it is important to limit the formation of dust that contains asbestos both during the collection of the sample and while cleaning up after. The person who takes the sample will typically need an air vacuum cleaner that is HEPA-filtered as well as a spray bottle filled with water and disposable coveralls as protection. When they are performing the task they should wear a respirator compliant with AS/NZS1716 : 2003 Respiratory protection device. It is recommended to collect samples on the day that isn't too windy. Also, turn off the cooling or heating system. This will reduce the airborne asbestos particles.

When collecting the sample make sure the area is completely sealed and that pets and children can be allowed to enter. Clean the area to be sampled with a damp rag, and wipe all tools and equipment that were used during the sampling process after it is completed. Place the rag into a plastic bag, mark it as asbestos waste, and dispose of it in an asbestos-free facility that is approved by the government. Place the bag that you re-sealable with the sample in a separate plastic bag, then seal it all before declaring it asbestos waste. Wet down the area to be cleaned again and place a plastic drop sheet over it, to catch any fibres that escape.

Asbestos samples are typically collected by using a pump and cassette system that is pre-assembled. It is essential that the cassette is not filled with dust as this can obscure the fibres of the filter and create distortion in the result. If the sample is taken in an area with high amounts of dust that is not fibrous the smaller volume of air could be used.

While most research is focused on asbestos fibers that are long however, epidemiological studies have shown that exposure to asbestos fibres that are short may cause mesothelioma or lung cancer too. This suggests that size is just one of the variables that influence the pathogenicity of asbestos fibres and that other factors such as chemical properties such as dispersion staining, polarization and etching times are also involved.

Identifying Professionals

Asbestos fibers may become airborne when they are disturbed or spread. Inhaling these tiny fibers can cause lung disease. These microscopic fibers may cause asbestosis or mesothelioma aswell in other neurological and respiratory diseases. The time to develop symptoms can take anywhere between 20 and 50 years after exposure.

Unaffected asbestos is not a health risk, but when insulation, shingles and flooring get damaged or wear out they could release harmful fibers. This could happen during a renovation or demolition project, or in normal home use or when the material ages.

If you are planning to redesign your home, you should ask your local health or environmental officials whether the building has asbestos. If asbestos is discovered in your home, have it checked prior to when any work is started by an asbestos inspector who is accredited.

When you're planning to renovate an older home Make sure that any contractors you choose to hire have the appropriate qualifications. They should be able to provide an asbestos survey and report that contains an evaluation of the condition of any asbestos-containing material (ACM) and their ability to be friable. The survey should also state whether the contractor plans to remove or leave the ACM intact.

Minor repairs are possible on some ACM. However, only a professional certified in asbestos safety is able to tackle these. Whatever the kind of repair, the area should be kept separate from the rest of the home and any equipment or clothing should be placed in plastic bags and marked with a warning in order to prevent cross-contamination.

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

Professionals are also able to physically remove ACM. The materials are then soaked in order to enable them to be cut using various tools without releasing harmful fibers. The materials are then put in airtight, tough containers that are leakproof.

Removing or replacing Asbestos

Asbestos is invulnerable to corrosion and heat. This makes it a great material for a myriad of products like wallboards insulation, fireproofing and auto brakes. Asbestos is a poisonous substance that can cause respiratory issues when fibers are breathed into. These fibers can cause tissue inflammation and scarring of the lungs. This can be detrimental to breathing and can cause serious health issues.

Asbestos is found in many areas of a home, including floor and ceiling tiles roof shingles, exterior siding, cement pipe and asbestos-containing joint compound. Examine these areas for water damage, abrasions, or tears. If the material is only slightly damaged, it may be safe to touch or even disturb. If the material requires to be repaired or replaced, or you are planning to make changes to your home which could damage it, then consult with an asbestos professional.

These experts can conduct a visual inspection and take samples. They can also provide suggestions on what adjustments are required and who qualifies. It is essential that you let experts manage your asbestos. Certain of these professionals have specific training in particular products, and only they are qualified to perform remedial work on them.

You can also contact your state's local Health Department or Regional Office of the U.S. Environmental Protection Agency to inquire about asbestos case-related training programs that are available in your region. Beware of companies that claim to be experts in asbestos removal. These firms pose a threat since they promote or perform unnecessary removals, thereby increasing the likelihood of harmful fibers being released.

The American Lung Association does not endorse these companies. It is essential to thoroughly research the company before hiring an asbestos professional to ensure it is fully insured and certified. You can also request references from past clients, as well as proofs of accreditation and insurance coverage. You should also inquire with your state or local health and environmental authorities for the proper procedures to follow when you are planning to renovate your home.
