How to Identify Asbestos

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

Some of these diseases have a long latency period. It's difficult to identify an issue until it's long gone.

Identifying Asbestos

Asbestos is an assortment of minerals that are naturally occurring. They were once utilized in building materials due to their anti-corrosive, fire-proof and insulation properties. Inhaling the tiny fibres could pose health risks. This can lead to diseases such as mesothelioma or asbestosis. The symptoms of these illnesses don't manifest until years, if not decades after the initial exposure. They are often mistaken for flu-like symptoms. This is the reason it's so important for people to be aware of how to recognize asbestos.

The most effective method to detect asbestos is by medical tests that check for asbestos lung diseases. These tests include a physical exam, chest X rays and lung function tests. These tests aren't enough to diagnose asbestos-related diseases. They should be paired with a detailed patient history that includes details about the patient's job, home, as well as the cultural context.

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

If you suspect that a product might contain asbestos, you can collect a sample of it. It is crucial that you only use a professional to remove asbestos, as it's a complex process and requires special equipment. Send the sample to an accredited asbestos analysis laboratory through the National Voluntary Laboratory Assessment Program (NVLAP). A list of laboratories can be found on the NVLAP website.

Certain groups of people are at a greater chance of accidentally damaging asbestos. This includes plumbers, construction workers, and electricians, because they are most likely to come across asbestos-containing materials in renovations and maintenance. It's a good idea for all workers in these areas to complete an asbestos awareness training course to ensure they are aware of the dangers and are able to use the proper precautions.

Take Samples

To conduct asbestos testing or an inspection, a sample from the suspected material is required. The sample could be taken by an asbestos expert or by the homeowner, however careful consideration should be taken to minimise the generation of dust that contains asbestos throughout the collection of the sample as well as when cleaning up afterwards. Typically, the person who is taking the sample should be equipped with an HEPA-filtered vacuum cleaner, an water spray bottle and disposable coveralls to protect themselves. While carrying out the task, they should wear a respirator that is compliant with AS/NZS1716 : 2003 Respiratory protection device. It is best to conduct the sampling on a calm, non stormy day. Also, ensure that heating or cooling systems are turned off as this will minimise the release of any asbestos-containing airborne particles.

If you are collecting the sample, make sure that the area is fully closed off and that pets or children aren't allowed in. Wet down the area to be sampled with an abrasive rag, then clean any tools and equipment utilized after the sample has been completed. Place the rag into a plastic bag, mark it as asbestos waste and dispose of it in an approved asbestos disposal facility. Place the resealable bag along with the sample in a separate plastic bag. Secure it all before labeling it as asbestos waste. Place a dropsheet of plastic over the area that needs to be cleaned, and then wet it again. This will trap any fibres that escape.

Asbestos is typically removed using a pre-assembled pumps and cassette system. It is crucial to ensure that the cassette doesn't get stuffed with dust. This could obscure the fibres and alter the results. If the sample is collected in an area with high levels of dust that is non-fibrous, smaller volumes of air can be employed.

The epidemiological studies found that asbestos fibres of short length can also cause mesothelioma and lung cancer. This suggests that size is only one of the factors influencing the pathogenicity of asbestos fibres and that other parameters like chemical properties such as dispersion staining, polarization and etching times are also involved.

Identifying Professionals

When asbestos fibers are disturbed or spread they can airborne. These microscopic fibers, once inhaled, can trigger lung diseases. These can cause mesothelioma and asbestosis as well as other neurological and respiratory ailments. The time between onset and recurrence of symptoms can vary from 20 to 50 years after exposure.

Unaltered asbestos is not a health hazard, but when insulation, shingles and flooring are damaged, they might release harmful fibers. This could happen when you are working on a renovation or demolition project, and also during normal home use or aging.

If you're planning to renovate your home, make sure you check with local environmental or health officials to determine if the building is made up of asbestos materials. If any material is found and inspected, you must have it checked by an accredited asbestos inspector before you begin any work.

If you're renovating an older home, be sure that the contractors you hire have the appropriate credentials. They must be able to provide an asbestos report and survey that includes an assessment on the condition of any ACM (asbestos-containing material) and their friability. The survey should also specify whether the contractor plans to remove or leave the ACM intact.

Minor repairs are feasible on certain ACM. However, only a professional who is educated in the safe handling of asbestos is able to tackle these. No matter what repair is made it is essential that the area be sealed off from the rest of your home. Any contaminated clothing or equipment should be put in plastic bags and labeled with a warning to prevent cross-contamination.

Professionals can seal or cover ACM to stop it from dispersing fibers into the atmosphere. Sealing (encapsulation) involves treating the material with a substance that binds or coats fibers to keep them from being airborne. This can be done on insulated pipes or to cover old shingles.

Professionals can also physically remove ACM. The materials are first wetted to allow them to be cut with various tools without releasing harmful fibers. The materials are then placed in airtight, tough containers that are leakproof.

Repairing or removing Asbestos

Asbestos is impervious to corrosion and heat. This makes it an ideal material for a myriad of products like wallboards, fireproofing insulation, and auto brakes. Asbestos can be a poisonous material that can cause respiratory issues when fibers are inhaled. These fibers can cause tissue inflammation and scarring in the lungs. This can affect breathing and lead to serious health issues.

Asbestos is found in numerous areas of a home, including floor and ceiling tiles roof shingles, exterior siding, cement pipe, and asbestos-containing joint compound. Be sure to check these areas for water damage, abrasions, or tears. A little damaged material could be safe as long as it's not touched or disturbed. However should the material be in need of repair or you plan to make changes to your home that might disturb it, you should consult an asbestos professional.

These experts can carry out a visual inspection and also take samples. They can also give you advice about the corrective measures that need to be done and who is qualified to make them. It is vital that you only have these professionals manage your asbestos. They are educated in specific products and should be permitted to correct them.

You should also contact your state's local Health Department or Regional Office of the U.S. Environmental Protection Agency to learn about asbestos training programs available in your area. Be aware of firms who claim to be experts in asbestos case removal. These firms can be hazardous because they promote unnecessary removals or make them in a way that isn't properly done and increase the risk of releasing harmful fibers.

The American Lung Association does not endorse these companies. Before hiring an asbestos professional, it is important to conduct a thorough investigation of the company to ensure it's accredited and insured. You can also request references from past clients, as and proof of insurance coverage and accreditation. You should also check with your state or local health and environmental authorities for the appropriate guidelines to follow if you plan to remodel your home.
