How to Identify Asbestos

In the last century asbestos was used in a variety of products to make them stronger, more fire-resistant and less costly. But exposure to airborne asbestos fibers can lead to lung diseases like mesothelioma and asbestosis.

Certain of these diseases could have a long latent period. This means it is difficult for people to identify a problem before it's too late.

Identifying Asbestos

Asbestos is a variety of minerals that are naturally occurring. They were once used in building materials for their fire retardant, corrosion-resistant and insulating properties. It could, however, pose health risks when the microscopic fibers are inhaled. This can lead to diseases such as mesothelioma and asbestosis. These diseases can take a long time, or even decades, to be diagnosed. They are often interpreted as flu-like symptoms. It is essential that people know how to recognize asbestos.

The most commonly used method to detect asbestos is by medical tests that check for lung diseases. These tests usually include a physical examination, chest X-rays and tests for pulmonary function. However, asbestos-related illnesses aren't diagnosed with these tests alone, as they have to be taken with a thorough patient history that looks at a person's home, work and social environment.

It is possible to discover asbestos in a diverse variety of building products and materials, including cement products, paints, floor tiles, adhesives, Artex, insulation, doors, partitions and cladding. Asbestos is difficult for people to detect because the fibers are so tiny and light. They are able to effortlessly glide through the air and inhale without anyone not even realizing. They don't emit any distinct smells either.

If you suspect that a product could be contaminated with asbestos, you can collect a sample of it. This should be done by a trained professional, because the process of removing asbestos is complicated and requires specialized equipment. Patch the sample with duct tape in order to prevent the release of fibers and take it to an asbestos analysis lab accredited by the National Voluntary Laboratory Accreditation Program (NVLAP). A list of accredited laboratories is available on the NVLAP website.

Certain groups of people are more at risk of accidentally disturbing asbestos. Construction workers, plumbers, and electricians are at risk of exposure to asbestos during renovations and maintenance. It's a good idea to encourage those who work in these fields to complete an asbestos awareness training course to make sure they are aware of the dangers and are able to take the correct precautions.

Taking Samples

A sample of the suspected material is required for asbestos testing or inspection. This sample can be taken by a qualified asbestos consultant or by the homeowner, but care must be taken to minimize the production of dust that contains asbestos both when collecting the sample and when cleaning up after. Typically the person taking the sample should have a vacuum cleaner that is HEPA-filtered, an water spray bottle and disposable coveralls to protect themselves. While carrying out the task, they must wear a respirator in accordance with AS/NZS1716 : 2003 Respiratory protective device. It is best to conduct the sample collection on a non windy day and make sure that cooling or heating systems are turned off, since this will reduce the release of any asbestos-containing airborne particles.

When you collect the sample, ensure that the area is fully closed off and that pets or children are not allowed in. After the sample has been taken clean all equipment and tools using a damp cloth. Place the rag into a plastic bag and label it as contaminated waste, and dispose of it in an approved asbestos disposal facility. Place the resealable bag and the sample in another plastic bag, and seal it before marking it as asbestos waste. Place a dropsheet of plastic over the area that must be cleaned. Then, wet it again. This will catch any fibres that are released.

Asbestos samples are typically gathered by using a pump or cassette system that is pre-assembled. It is crucial to ensure that the cassette does not get overloaded with dust. This could block the fibres and bias the results. If the sample is located in an area where there are high levels of non-fibrous dust, it might be necessary to use a smaller volume of air.

While most testing focuses on long asbestos fibers but epidemiological studies have proven that exposure to short asbestos fibres may cause mesothelioma or lung cancer too. This suggests that size is not the only factor that affects the pathogenicity asbestos fibres. Other parameters such as chemical property, polarization dispersion staining, as also the time required to etch are also a factor.

Identifying Professionals

Asbestos fibers may become airborne when they are disturbed or spread. Inhaling these microscopic fibers can cause lung diseases. They can cause mesothelioma, asbestosis or other neurological and respiratory problems. The latency period for many symptoms can be anywhere between 20 and 50 years after exposure.

Infrequently disturbed asbestos does not pose the risk of health hazards, but when the insulation, shingles, or flooring are damaged or deteriorate they may release harmful fibers. This could happen during a renovation or demolition project, as well as in normal use of the home or as the house ages.

If you are planning to remodel your home, inquire with your local health or environmental department if the building contains asbestos. If asbestos is found then it should be examined by an accredited asbestos inspector before any work can begin.

If you are renovating an older home, be sure that the contractors you hire have the appropriate credentials. They should be able to conduct an asbestos survey and report that includes an assessment of the condition of any asbestos-containing material (ACM) and their ability to withstand friability. The survey should also specify whether the contractor will take away 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 type of repair, the area should be kept separate from the surrounding area and any contaminated equipment or clothing must be put in plastic bags and marked with a warning to avoid cross-contamination.

Professionals can seal ACM or cover it to stop the fibers from being released into the air. Sealing (encapsulation) also referred to as encapsulation, is the process of treating the material in a manner that binds and seals the fibers so they don't become airborne. This can be done on insulated piping or to cover old shingles.

Professionals can also physically remove ACM. This is accomplished by wetting the materials so they can be cut or scraped with different tools without releasing the dangerous fibers. The materials are then put in airtight and durable containers that are leakproof.

Repairing or removing Asbestos

Asbestos Settlement is abrasive to corrosion and heat, which has made it an extremely useful ingredient in thousands of products such as wallboard materials, fireproofing insulation and auto brakes. Asbestos can be a poisonous material that can cause respiratory issues when fibers inhaled. These fibers can cause tissue inflammation and scarring of the lungs. This could be detrimental to breathing and can cause serious health problems.

Asbestos is present in many parts of your home including roof shingles, cement pipes, floor and ceiling tiles and joint compound containing asbestos. It is crucial to check these areas frequently for tears, abrasions or water damage. If the material is only little damaged, it might be safe to touch or move. If the material needs to be repaired or if you are planning to make changes to your home that could disturb it, then you should consult an asbestos professional.

They can conduct an inspection visually and also take samples. They can also give you guidance on the corrective measures required and who qualifies. It is essential to let these professionals handle your asbestos. Some of them have specific training in particular asbestos products, and only they must perform the corrective work on them.

In addition to consulting an asbestos-certified asbestos professional, you should contact your local or state health department or regional office of the U.S. Environmental Protection Agency for information about asbestos training programs in your area. Be aware of companies that falsely claim to specialize in asbestos removal. These companies can be risky since they encourage removals that are not needed or do them incorrectly and increase the risk of releasing harmful fibers.

The American Lung Association does not endorse these companies. Before you hire an asbestos professional it is crucial to investigate the company thoroughly to ensure it's certified and insured. You can also request references from previous clients, as well as evidence of accreditation as well as insurance coverage. It is also recommended that you consult your state or local environmental and health departments to learn about the procedures that must be followed if planning to do any remodeling in your home.
