How to Identify Asbestos
In the past century, asbestos was used in thousands of products to make them more durable, less prone to fire and less costly. Inhaling asbestos fibers in the air can cause lung diseases like mesothelioma or asbestosis.
Some of these illnesses can have a long-lasting latent period. It's hard to spot the presence of a problem until it is too far gone.
Identifying Asbestos
Asbestos is an assortment of minerals that are naturally occurring. They were once utilized in building materials due to their corrosion-resistant, fireproof and insulation properties. However, it can cause health problems when the microscopic fibers are inhaled. This can lead to the development of diseases like mesothelioma and asbestosis. The symptoms of these diseases don't manifest until years, if not decades, after the first exposure. They're frequently misinterpreted as flu-like symptoms. It's essential to know how to recognize asbestos.
The most common way to identify asbestos is through medical tests that check for lung diseases. These tests usually include physical examinations including chest X-rays, lung function tests. However, asbestos-related illnesses aren't identified by these tests alone, as they must be paired with a thorough medical history that includes the person's home, work and the cultural context.
It is possible to find asbestos in a wide assortment of building products and materials, including cement products, paints, floor tiles, adhesives, Artex, insulation, doors, partitions, and cladding. However, asbestos is difficult to recognize because the harmful fibers are tiny and light that they could easily flounder in the air and inhale without being recognized. They don't have distinct smells either.
You can take a tiny sample if you suspect an item is contaminated with asbestos. This should only be performed by a trained professional, as removing asbestos is very complex and requires special equipment. Patch the sample with duct tape to stop the release of fibers, and take it to an asbestos analysis laboratory accredited by the National Voluntary Laboratory Accreditation Program (NVLAP). The NVLAP website has a list of accredited laboratories.
It's quite easy to damage asbestos and the risk of doing so is higher for certain categories of people. Plumbers, construction workers and electricians are at risk of asbestos exposure in maintenance and renovations. It's recommended for all workers in these areas to complete an asbestos awareness training course to make sure they are aware of the risks and can use the proper precautions.
Take Samples
A sample of the suspected material is required for asbestos testing or inspection. The sample could be taken by an asbestos expert or by the homeowner, but careful consideration should be taken to limit the formation of dust that contains asbestos throughout the collection of the sample, and during cleaning up after. The person who takes the sample will usually require an air vacuum cleaner that is HEPA-filtered and a spray bottle of water and disposable coveralls as protection. When performing the task, they should wear a respirator in accordance with AS/NZS1716 : 2003 Respiratory protection device. It is recommended to collect samples on a day that is not too windy. Also, turn off the cooling or heating system. This will reduce the release of airborne asbestos particles.
When collecting the sample make sure that the area is closed off and that any pets or children are not allowed in. Wet down the area to be sampled with a damp rag, and clean all equipment and tools used once the sampling is completed. Place the cloth in a plastic bag and label it as contaminated waste, and dispose of it in an asbestos disposal facility that is approved. Place the re-sealable bag with the sample inside a second plastic bag, and seal it all before marking it as asbestos waste. Clean the area with water to be cleaned once again and place a plastic drop sheet over it to catch any fibres released.
Asbestos is usually collected using a pre-assembled pump as well as a cassette system. It is vital that the cassette isn't filled with dust since this could block the fibres on the filter and create distortion in the result. If the sample is collected in an area with high amounts of dust that is not fibrous a smaller volume of air can be employed.
While most testing focuses on long asbestos fibers, the epidemiological studies have shown that exposure to asbestos fibres that are short can trigger mesothelioma and lung cancer as well. This indicates that size isn't the only factor influencing the pathogenicity asbestos fibres. Other factors like chemical property, polarization dispersion staining, as also the time of etching are also important.
Identifying Professionals
When asbestos fibers are dispersed or disturbed, they can become airborne. These tiny fibers, if inhaled, can cause lung disease. They can cause mesothelioma, asbestosis or other respiratory and neurological problems. The time of onset for many symptoms can be anywhere between 20 and 50 years after exposure.
Unaltered asbestos isn't an hazard to health, but when materials such as flooring, insulation and shingles are damaged, they could release harmful fibers. This can occur during a renovation or demolition project, or when you use your home for normal activities or as the house ages.
If you are planning on transforming your home, check with local officials from the environmental or health department to determine if your home contains asbestos-containing materials. If asbestos is found in your home, it is recommended to have it checked prior to when any work is started by an accredited asbestos inspector.
If you are renovating an older house Make sure that any contractors you employ have the proper qualifications. They should be able to conduct an asbestos survey and report that contains an evaluation of the condition of any asbestos-containing material (ACM) and their brittleness. The report should include whether or the contractor will take away the ACM.
Minor repairs are possible on certain ACM. However only a professional educated in the safe handling of asbestos is able to tackle these. 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 placed into plastic bags and labeled with a warning to avoid cross-contamination.
Professionals can seal or cover ACM to prevent it from release of fibers into the air. Sealing (encapsulation) is also referred to as encapsulation, involves treating the material in a manner that binds and seals the fibers to ensure they don't become airborne. This can be done to insulated pipes or to cover old shingles.
Professionals can also physically remove ACM. This process begins by wetting the materials so that they can be cut or scraped using a variety of tools without releasing the hazardous fibers. The materials are then put in airtight, sturdy containers that are leakproof.
Repairing or Removing Asbestos
Asbestos is invulnerable to corrosion and heat This has made it a very useful material in thousands of products such as wallboards, fireproofing insulation and auto brakes. Asbestos is a harmful substance that can cause respiratory problems when fibers inhaled. These fibers can cause tissue inflammation and scarring of the lungs. This could impact breathing and cause serious health issues.
Asbestos is present in many parts of your home, including roof shingles, cement pipes, floor and ceiling tiles and joint compound made of asbestos. Check these areas for water damage, abrasions, or tears. Material that is slightly damaged may be safe if it is not manipulated or damaged. If the material must be repaired or replaced, or you are planning to make changes to your home that could disturb it, then seek advice from an asbestos professional.
These professionals can conduct an inspection of the visuals and take samples. They can also offer advice on the corrections that must be done and who is qualified to perform them. You should only let these professionals handle asbestos compensation. They are educated in specific products and should be permitted to correct them.
You should also contact your local or State Health Department or Regional Office of the U.S. Environmental Protection Agency to inquire about asbestos training programs offered in your region. Be aware that there are firms which falsely claim they specialize in asbestos removal. These firms can be hazardous because they promote unnecessary removals or do them incorrectly and increase the risk of the release of harmful fibers.
The American Lung Association does NOT endorse these companies. It is important to research the company thoroughly before hiring an asbestos professional to ensure that the company is fully insured and certified. You can also request references from previous clients along with evidence of accreditation and insurance coverage. You should also check with your state or local health and environmental agency for the correct steps to follow if are planning to remodel your house.
