How to Identify Asbestos
In the past century asbestos was used in a myriad of products to make them stronger, more fire-resistant and less costly. Inhaling asbestos fibers in the air can trigger lung diseases like asbestosis or mesothelioma.
Some of these diseases have a long latency period. It can be difficult to recognize the presence of a problem until it is too long gone.
Asbestos Identification
Asbestos is a range of naturally occurring minerals. They were used in building materials because of their fire-resistant, corrosion-resistant and insulating properties. However, it can create health risks if the microscopic fibers inhaled. This can lead to diseases such as mesothelioma or asbestosis. These diseases can take years, or even decades, to display their symptoms. They are often mistaken as flu-like symptoms. It's crucial that people know how to identify asbestos.
Tests for medical conditions that detect lung disease are the most common way to identify asbestos. These tests usually consist of a physical examination, chest X-rays and lung function tests. However, asbestos-related ailments can't be identified by these tests on their own, since they require a combination with a thorough patient history that includes the person's home, work and the cultural context.
Asbestos can be found in a wide range of building materials and products, including cement, paints, and floor tiles. It is also found in doors, insulation, partitions, cladding, and Artex. However, asbestos can be difficult to detect because the harmful fibers are tiny and light that they could easily float in the air and be inhaled without being observed. They also don't create any distinctive smells.
You can take a tiny sample if you suspect the substance you're looking at has asbestos. This should be done by a professional who is trained, as removing asbestos is very complicated and requires specialized equipment. Patch the sample using duct tape to avoid 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 has a list of accredited laboratories.
Certain groups of people are at greater chance of accidentally damaging asbestos. This includes plumbers, construction workers, and electricians, since they are most likely to come across asbestos-containing materials in renovations and maintenance. It's a good idea for those who work in these fields to complete an asbestos awareness course so that they understand the dangers and are able to make the right precautions.
Take Samples
For asbestos testing or inspection, a sample of the suspect material is needed. The sample could be taken by a professional asbestos consultant or by the homeowner, but it is important to minimise the generation of dust containing asbestos that is airborne throughout the collection of the sample as well as when cleaning up after. Typically, the person taking the sample should be equipped with a HEPA-filtered vacuum cleaner an water spray bottle and disposable coveralls to protect themselves. When they are performing the task they should wear a respirator in accordance with AS/NZS1716 : 2003 Respiratory protection device. It is recommended to collect samples on the day that isn't windy and turn off the cooling or heating system. This will limit the airborne asbestos particles.
When collecting the sample make sure that the area is sealed and that no children or pets are allowed to get into the. Make sure to saturate the area to be sampled using an abrasive rag, then wipe all tools and equipment used once the sampling is completed. Place the rag into a plastic bag, label it as asbestos waste and dispose of it in an approved asbestos disposal facility. Place the bag that you re-sealable with the sample in another plastic bag, and seal it all up before declaring it Asbestos settlement waste. Place a plastic dropsheet over the area that must be cleaned, and then wet it down once more. This will trap any fibres that escape.
Asbestos sample are typically taken by using a pump or cassette system that is pre-assembled. It is vital that the cassette is not overloaded with dust, because this could obscure the fibers on the filter and cause a bias in the result. If the sample is collected in an area with high levels of dust that is not fibrous, the smaller volume of air could be used.
The epidemiological studies showed that asbestos fibres that are short can also cause mesothelioma and lung cancer. This shows that size isn't the only factor that affects the pathogenicity of asbestos fibers. Other factors like chemical properties, polarization and dispersion staining, as well as the time to etch are also involved.
Identifying Professionals
When asbestos fibers are displaced or disturbed, they can become airborne. If inhaled, these tiny fibers can cause lung diseases. They could cause mesothelioma, asbestosis or other neurological and respiratory issues. Many symptoms may manifest in the 20 to 50 years following.
Undisturbed asbestos does not pose an health risk, however when materials like insulation, shingles, or flooring are damaged or worn out and release harmful fibers. This can happen when you are working on a renovation or demolition project or even in normal home use or as a result of aging.
If you are planning to renovate your home, ask local health or environment officials whether the building has asbestos. If asbestos-containing materials are found, have it inspected by an asbestos inspector who is accredited prior to beginning any work.
When you're renovating an older home, make sure any contractors you hire have the necessary qualifications. They should be able to conduct an asbestos survey and report which includes an assessment of the state of any asbestos-containing material (ACM) and their brittleness. The survey should also state whether the contractor plans to remove or leave the ACM intact.
Minor repairs are feasible on certain ACM. However only a professional educated in asbestos safety should attempt these. Whatever repair you make the area must be protected from the rest of your home. Any contaminated clothing or equipment should be placed in plastic bags and marked with a warning in order to avoid cross-contamination.
Professionals can seal or cover ACM to prevent it from release of fibers into the air. Sealing (encapsulation) involves treating the material with a chemical that binds or coats fibers to keep them from being airborne. This can be done on insulated piping, or to cover old shingles.
Professionals can also physically remove ACM. The materials are first wetted in order to enable them to be cut with various tools without releasing harmful fibers. Then, they place the materials in durable, leak-proof air-tight containers for safe disposal.
Removing or replacing Asbestos
Asbestos is invulnerable to heat and corrosion and has been a very useful material in hundreds of products, including wallboard, fireproofing insulation and auto brakes. However, asbestos is a toxic material that can cause respiratory issues when the fibers are inhaled. In most cases, these fibers end up trapped in the lungs and may cause tissue inflammation and scarring, which can hinder breathing and cause serious health issues.
Asbestos can be found in numerous areas of a home which includes roof shingles cement pipes, floor and ceiling tiles, and joint compound that contains asbestos. Examine these areas for water damage or abrasions. Material that is slightly damaged may be safe if it is not manipulated or smashed. However when the material is in need of repair or you plan to make changes to your home that might disturb it, you need to seek out an asbestos expert.
These professionals can perform a visual inspection as well as take samples. They can also advise you about what corrections need to be made and who is qualified to make them. It is recommended that only these professionals handle asbestos. Some of these professionals have been trained specifically for specific products, and they are the only ones who should perform corrective work on 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-related training programs that are available in your area. Be aware that there are firms that falsely claim to be experts in asbestos removal. These firms pose a threat as they encourage or conduct ineffective removals, which increases the possibility of harmful asbestos fibers being released.
The American Lung Association does NOT endorse these companies. It is crucial to conduct a thorough investigation of the company before hiring an asbestos professional to ensure that it is fully insured and certified. You can also ask for references from past clients, along with evidence of accreditation as well as insurance coverage. It is also recommended to check with your local or state health and environmental authorities for the correct procedures to follow when you are planning to remodel your house.
