How to Identify Asbestos

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

Certain diseases have a long period of latency. This makes it difficult for people to detect the issue before it's late.

Asbestos is a class of naturally occurring minerals that were previously used in building materials since they are fire-resistant, corrosion resistant and insulate. Inhaling tiny fibres of asbestos can pose health risks. This can lead to diseases such as mesothelioma or asbestosis. These diseases can take a long time, or even decades, to be diagnosed. They are often mistaken as flu-like symptoms. This is the reason it's so important for people to know how to identify asbestos.

The most commonly used method to detect asbestos is via medical tests to look for lung diseases. These tests usually include physical examinations as well as chest X-rays, and pulmonary function tests. These tests are not sufficient to identify asbestos-related diseases. They must be combined with a comprehensive history of the patient that includes details about the patient's job, home, as well as the environment in which they live.

It's possible to find asbestos in a broad range of building products and materials such as cement products flooring tiles, paints, adhesives, Artex, insulation, doors, partitions and cladding. Asbestos is difficult to identify because the fibers are small and light. They are able to effortlessly glide throughout the air and then inhale without anyone noticing. They don't have distinct smells or odors.

If you suspect that a particular material might contain asbestos, you can take a sample of it. This should only be done by a qualified professional, as removing asbestos is very complex 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 laboratory that is accredited by the National Voluntary Laboratory Accreditation Program (NVLAP). The NVLAP website provides an inventory of accredited laboratories.

Certain groups of people are at greater danger of accidentally touching asbestos. Plumbers, construction workers and electricians are at risk of exposure to asbestos during renovations and maintenance. Anyone who works in these fields should take an asbestos awareness course to ensure they are aware of the risks and know how to take the proper precautions.

Take Samples

For asbestos testing or inspection, a sample of the material that is suspect is required. The sample can be taken by an asbestos consultant or a homeowner. However, it is important to ensure that you don't create asbestos-containing dust that is airborne during the cleaning and collection process. Typically, the person who is taking the sample must have a HEPA-filtered vacuum cleaner an water spray bottle and disposable coveralls to protect themselves. When they are performing the task they must wear a respirator that is in compliance with AS/NZS1716 : 2003 Respiratory protection device. It is recommended to carry out the sampling on a calm, non windy day and ensure that cooling or heating systems are turned off, as this will minimise the release of any asbestos-containing airborne particles.

When collecting the sample make sure that the area is closed off and that pets or children are not permitted in. After the sample has been collected and cleaned, clean the instruments and equipment using a damp cloth. Place the rag into a plastic 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 into a second plastic bag. Secure it all before marking it asbestos waste. The area will be cleaned a second time and place a drop sheet over it, to catch any fibres that are released.

Asbestos samples are usually collected by using a pump or cassette system that is pre-assembled. It is important to ensure that the cassette is not filled with dust as this may obscure the fibres of the filter and cause distortion in the result. If the sample is collected in an area with high levels of dust that is not fibrous, smaller volumes of air can be used.

While the majority of studies focus on long asbestos fibers however, epidemiological studies have revealed that exposure to short asbestos fibres may cause mesothelioma or lung cancer too. This shows that size is not the only factor influencing the pathogenicity of asbestos fibres. Other parameters like chemical property, polarization and dispersion staining, and etching time are also involved.

Identifying Professionals

When asbestos fibers are disturbed or spread, they can become airborne. These microscopic fibers when inhaled, can cause lung disease. These microscopic fibers can trigger asbestosis or mesothelioma as well in other neurological and respiratory diseases. Many symptoms can appear 20 to 50 years later.

Asbestos that is not disturbed does not pose a health risk, but when materials like insulation, asbestos settlement shingles, and flooring become damaged or degraded they may release harmful fibers. This can occur when you are working on a renovation or demolition project, or in normal home use or aging.

If you are planning on transforming your home, make sure you check with local environmental or health officials to determine if the structure is made up of asbestos materials. If asbestos is found in your home, it is recommended to get it checked before any work can begin by an asbestos inspector who is accredited.

If you are renovating an older home, make sure that any contractors you employ are licensed and certified. They should be able provide an asbestos survey and report that contains an assessment of the condition and condition of any asbestos-containing material (ACM) and their ability to be friable. The survey should also include whether the contractor will remove or leave the ACM intact.

Minor repairs are possible on certain ACM however only a certified professional who has been trained in methods for safely handling asbestos should attempt the repairs. No matter what type of repair you make it is essential that the area be protected from the rest of your home. Any clothing or equipment should be put into plastic bags and marked with a warning to avoid cross-contamination.

Professionals can seal ACM or cover it to stop the fibers from getting released into the environment. 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 from a structure. The materials are first soaked so that they can be cut with various tools without releasing harmful fibers. Then, they place the materials in durable, leakproof air-tight containers to ensure safe disposal.

Repairing or removing Asbestos

Asbestos is impervious to corrosion and heat. This makes it a suitable material for a myriad of products such as wallboard as well as fireproofing insulation and auto brakes. But asbestos is also an irritant that can cause respiratory issues when the fibers are inhaled. These fibers can cause tissue inflammation and scarring of the lungs, which can be detrimental to breathing and can cause serious health issues.

Asbestos is present in a variety of places within the home, including floor and ceiling tiles roofing shingles exterior siding, cement pipe, and asbestos-containing joint compound. It's important to check these areas frequently for damage, tears, or damage. If the material is only slightly damaged, it could be safe to touch or even disturb. However when the material is in need of repair or asbestos settlement you are planning to make changes in your home that might disturb it, you should consult an asbestos professional.

These experts can carry out an inspection by visuals and also take samples. They can also give you advice on what corrections are required and who's qualified. It is essential that you only have experts handle your asbestos. They are certified in specific products and should only be allowed to correct the problem.

It is also recommended to contact your state's local Health Department or Regional Office of the U.S. Environmental Protection Agency to find out about asbestos training programs offered in your region. Be aware that there are firms that falsely claim to be experts in asbestos removal. These firms can be hazardous because they promote unnecessary removals or conduct them improperly, increasing the danger of releasing harmful fibers.

The American Lung Association does not endorse these companies. Before hiring an asbestos specialist, it is important to thoroughly research the company to ensure that it is accredited and insured. You can also ask for references from former clients, as well as proof of accreditation and insurance coverage. It is also recommended to check with your state or local health and environmental agency for the correct steps to follow if intend to remodel your home.
