How to Identify Asbestos
Over the past century, asbestos was used to make a variety of products stronger and more resistant to fire and cheaper. Exposure to asbestos fibers in the air can cause lung disease such as asbestosis or mesothelioma.
Some of these diseases can have a long time of latent. It is difficult to detect an issue until it's long gone.

Asbestos is one of the naturally occurring minerals that were once used in building materials because they are fire retardant and corrosion resistant, as well as insulate. However, it can cause health problems when the microscopic fibers are inhaled. This often causes diseases like mesothelioma and asbestosis. These illnesses can take years, or even decades, to show their symptoms. They are often interpreted as flu-like symptoms. It's vital that people understand how to identify asbestos.
Medical tests that test for lung diseases are the most frequent method to find asbestos. The tests typically consist of a physical examination including chest X-rays, pulmonary function tests. These tests aren't enough to determine the presence of asbestos-related illnesses. They must be combined with a thorough history of the patient that includes the person's work, residence, asbestos settlement and the environment in which they live.
Asbestos can be found in a variety of construction products and materials, including cement, paints, and floor tiles. It can also be found in doors, insulation partitions, cladding and Artex. However, asbestos can be difficult to recognize since the dangerous fibers are so small and light that they could easily flounder in the air and breathed in without being detected. They also don't emit any distinctive smells.
You can collect a small sample if you suspect that the substance you're looking at has asbestos. It is imperative that only a professional remove asbestos since it's a complex process and requires special equipment. Patch the sample with duct tape in order to prevent the release of fibers and send it to an asbestos analysis laboratory accredited by the National Voluntary Laboratory Accreditation Program (NVLAP). The NVLAP website has a list of accredited laboratories.
Certain categories of people are more at risk of accidentally disturbing asbestos. Plumbers, construction workers, and electricians are at risk of exposure to asbestos when they work on renovations or maintenance. Everyone who works in these fields should take an asbestos awareness course to ensure that they are aware of the risks and how to take the necessary precautions.
Taking Samples
A sample of the suspected material is required for asbestos testing or inspection. The sample could be taken by an asbestos expert or a homeowner. However, it is important to take care not to produce asbestos-containing dust in the air during the cleaning and collection process. The person who takes the sample will typically need an air vacuum cleaner with HEPA filters, a spray bottle of water and disposable coveralls to provide protection. While carrying out the task, they should wear a respirator compliant with AS/NZS1716 : 2003 Respiratory protection device. It is recommended to take samples on a day that is not windy and shut off the cooling or heating system. This will minimize the airborne asbestos settlement particles.
If you are collecting the sample, ensure that the area is fully closed off and that any children or pets are not permitted in. After the sample is taken then clean up all equipment and tools using a damp cloth. Place the rag in a plastic bag, mark it as asbestos waste and dispose of it in an approved asbestos disposal facility. Place the re-sealable bag with the sample in another plastic bag, then seal it before marking it as asbestos waste. Place a dropsheet of plastic over the area that must be cleaned and then wet it down once more. This will collect any fibres released.
Asbestos samples are typically collected through a pump and cassette system that is pre-assembled. It is important to ensure that the cassette does not be suffocated with dust. This can obscure the fibres and alter the results. If the sample is located in an area that has significant levels of non-fibrous dust, it might be necessary to use smaller volumes of air.
While most testing focuses on long asbestos fibers however, epidemiological studies have shown that exposure to short asbestos fibres can trigger mesothelioma and lung cancer as well. This indicates that size is not the only one of the factors that affect the pathogenicity of asbestos fibres and that other factors such as chemical properties such as dispersion staining, dispersion polarization and asbestos Settlement etching time are also involved.
Identifying Professionals
When asbestos fibers are spread or disturbed, they can become airborne. If inhaled, these tiny fibers can cause lung diseases. These microscopic fibers can cause asbestosis or mesothelioma, as well in other neurological and respiratory disorders. The time to develop symptoms can be anywhere between 20 and 50 years after exposure.
Undisturbed asbestos does not pose an health risk, however when materials like insulation, shingles and flooring get damaged or wear out and release harmful fibers. This can happen during a demolition or renovation project, or even during normal home use or as a result of aging.
If you are planning to renovate your home, ask your local health or environmental department if the building contains asbestos. If any material is found, have it inspected by an asbestos-certified inspector before you begin any work.
If you're renovating an older home, be sure that any contractors you employ are licensed and certified. They should be able provide an asbestos survey and report that 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.
Minor repairs may be possible with certain ACM repairs, but only a professional trained in methods for safely handling asbestos should attempt them. Regardless of the type of repair, the affected area should be kept separate from the other areas of the house, and any contaminated equipment or clothing must be put in plastic baggies and labeled with a warning to avoid cross-contamination.
Professionals can seal ACM or cover it to keep fibers from being released into the atmosphere. Sealing (encapsulation) involves treating the material with a substance that binds or coats the fibers to keep them from being airborne. This can be done to insulated pipes or to cover old shingles.
Professionals can also physically remove ACM from a structure. This process begins by wetting the materials so they can be cut or scraped with many tools without releasing the hazardous fibers. The material is then put in airtight and durable containers that are leakproof.
Removing or repairing Asbestos
Asbestos is resistant to heat and corrosion which makes it an extremely useful material for thousands of products such as wallboards, fireproofing insulation and auto brakes. Asbestos can be a poisonous material that can cause respiratory problems when fibers are breathed into. Typically, these fibers become stuck in the lungs, and may cause scarring and inflammation of the tissues, which can make breathing difficult and lead to serious health issues.
Asbestos is present in many parts of a house including roof shingles, cement pipes as well as floor and ceiling tiles, as well as joint compound containing asbestos. Be sure to check these areas for water damage or abrasions. If the material is only slightly damaged, it could be safe to touch or disturb. However should the material be in need of repair or you are planning to make changes in your home that could disturb it, you must consult with an asbestos professional.
These professionals can conduct an inspection visually and collect samples. They can also offer advice on the corrections that must be done and who is qualified to carry out them. It is recommended that only these professionals handle asbestos. Certain of these professionals have specific training in particular products, and only they are qualified to perform remedial work on them.
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 available in your area. Be wary of companies who claim to be experts in asbestos removal. These firms can be hazardous since they encourage removals that are not needed or conduct them improperly which increases the risk of the release of harmful fibers.
The American Lung Association does NOT endorse these companies. It is important to do your research thoroughly before hiring an asbestos expert to ensure it is properly certified and insured. You can also request references from previous clients as along with proof of accreditation and insurance coverage. It is also recommended to examine your state's or local health and environmental agencies to find out what procedures should be followed if you're planning to make any changes at home.
