How to Identify Asbestos

Over the course of the last century, asbestos was used in a variety of products, to make them stronger, more fire-resistant and less expensive. But exposure to asbestos in the air fibers could cause lung diseases such as mesothelioma and asbestosis.

Certain diseases may have a long time of latent. It's difficult to identify the presence of a problem until it is too far gone.

Asbestos Identification

Asbestos is a variety of naturally occurring minerals. They were once utilized in building materials due to their fire retardant, corrosion-resistant and insulation properties. It could, however, pose health risks when the microscopic fibers are breathed in. This can lead to the development of diseases like mesothelioma and asbestosis. Symptoms of these illnesses don't appear until years, even decades after the initial exposure. They're often misinterpreted as flu-like symptoms. This is why it's important for people to know how to identify asbestos.

The most commonly used method to detect asbestos is through medical tests that test for lung disease. These tests include a physical exam as well as chest X-rays and lung function tests. However, asbestos-related illnesses aren't identified by these tests on their own, since they have to be taken with a thorough history of the patient which includes a thorough examination of a person's work, home and social environment.

It is possible to detect asbestos in a vast range of building products and materials, including cement products floor tiles, paints adhesives, Artex, insulation, doors, partitions, and cladding. However, asbestos can be difficult to identify because the harmful fibers are tiny and light that they can easily float in the air and breathed in without being detected. They don't have any distinct smells either.

You can take a small sample if you suspect a material contains asbestos. This should be done by a certified professional because the process of removing asbestos is complex and requires specialized equipment. Patch the sample using duct tape to avoid the release of fibers, and take it to an asbestos analysis laboratory accredited by the National Voluntary Laboratory Accreditation Program (NVLAP). The NVLAP website contains the list of accredited laboratories.

Certain categories of people are at a greater risk of accidentally disturbing asbestos. These include plumbers, construction workers, asbestos and electricians as they are more likely to encounter asbestos-containing materials during maintenance and renovations. Anyone working in these fields should attend an asbestos awareness course to ensure they are aware of the dangers and how to take the appropriate precautions.

Samples to take Samples

To conduct asbestos testing or an inspection for asbestos testing or inspection, a sample of the suspected material is required. This sample can be taken by a professional asbestos consultant or by the homeowner, however it is important to limit the formation of dust containing asbestos that is airborne both during the collection of the sample, and during cleaning up afterwards. The person 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 coveralls to provide protection. When they are performing the task they must wear a respirator in accordance with AS/NZS1716: 2003 Respiratory protection device. It is best to conduct the collection of samples on a non windy day and make sure that cooling or heating systems are turned off, to reduce the release of any airborne asbestos particles.

When collecting the sample, make sure that the area is sealed and that no pets or children can enter. Wet down the area to be sampled using an abrasive rag, then wipe all tools and equipment used once the sampling is completed. Place the rag in the bag, label it as asbestos waste, and dispose of it in an approved asbestos disposal facility. Place the resealable bag and the sample into a second plastic bag. Then, seal it all up before marking it as asbestos lawsuit waste. Make sure to rinse the area to be cleaned a second time and place a plastic drop sheet over it to catch any released fibres.

Asbestos samples are usually collected with the help of a pump and cassette system that is pre-assembled. It is important to ensure that the cassette does not get stuffed with dust. This can obscure the fibres and bias the results. If the sample is taken in an area that has significant levels of nonfibrous dust may be necessary to use less air.

While the majority of studies focus on asbestos fibers that are long however, epidemiological studies have found that exposure to short asbestos fibres may cause mesothelioma or lung cancer as well. This suggests that size is not the only factor that influences asbestos fibers' pathogenicity. Other parameters such as chemical property, polarization dispersion staining, and the time to etch are also involved.

Identifying Professionals

Asbestos fibres can become airborne when they are disturbed, or spread. These tiny fibers, if inhaled, can cause lung disease. These microscopic fibers can trigger mesothelioma or asbestosis as well as other neurological and respiratory disorders. Many symptoms can be noticed after 20 to 50 years.

Unaltered asbestos is not dangerous to health, however when the materials like flooring, shingles, or insulation are damaged, they may release harmful fibers. This can occur in the course of a renovation or demolition project, or even during normal home use or as a result of aging.

If you're planning to make changes to your home, you should ask your local health or environment department whether the building is asbestos-free. If asbestos-containing materials are found then it should be examined by an asbestos inspector who is accredited prior to any work being started.

If you are renovating an older home, be sure that any contractors you hire are licensed and certified. They should be able provide an asbestos survey and report which includes an assessment of the state of any asbestos-containing material (ACM) and their ability to withstand friability. The survey should specify whether or whether the contractor will eliminate the ACM.

Repairs of minor nature are possible with certain ACM, but only a professional trained in techniques for safely handling asbestos should attempt these repairs. Whatever repair is made the area must be sealed off from the rest of your home. Any contaminated clothing or equipment should be placed into plastic bags and labeled with a warning to prevent cross-contamination.

Professionals can seal ACM or cover it to stop fibers from getting released into the environment. Sealing (encapsulation) also referred to as encapsulation, involves treating the material in a way that binds and covers the fibers to prevent them from become airborne. This can be done to insulated piping or to cover old shingles.

Professionals can also physically remove ACM. The materials are initially soaked so that they can be cut using various tools without releasing dangerous fibers. Then they place the material in durable, leak-proof air-tight containers for safe disposal.

Repairing or Removing Asbestos

Asbestos is abrasive to heat and corrosion and has been a very useful material in many different products like wallboards, fireproofing insulation and auto brakes. But asbestos is also an extremely toxic substance that can cause respiratory issues when fibers are inhaled. In most cases, these fibers end up lodged in the lungs and can cause tissue inflammation and scarring which can make breathing difficult and cause serious health problems.

Asbestos can be present in a variety of places within homes, including ceiling and floor tiles roof shingles, exterior siding, cement pipe and asbestos-containing joint compound. Check these areas for damage, abrasions, or tears. Material that is slightly damaged may be safe as long as it's not touched or disturbed. If the material must be repaired or replaced, or you are planning to make changes to your home that could disturb it, then you should consult with an asbestos professional.

These experts can conduct an inspection of the visuals and take samples. They can also provide advice about what corrections need to be done and who is qualified to make them. Only experts handle asbestos. These professionals have been trained in specific asbestos products and should be permitted to correct 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-related training programs that are available in your area. Beware of companies who claim to be experts in asbestos removal. These firms are dangerous because they encourage or perform unneeded removals, which increase the likelihood of harmful fibers being released.

The American Lung Association does NOT endorse these companies. It is essential to research the company thoroughly before hiring an asbestos professional to ensure it is fully insured and certified. You can also request references from former clients as along with proof of insurance coverage and accreditation. It is also recommended to check with your local or state health and environmental agency for the appropriate procedures to follow if you plan to remodel your home.
