How to Identify Asbestos During the past century asbestos was used to make a myriad of products stronger and more resistant to fire, and less expensive. The exposure to asbestos fibers in the air can lead to lung diseases such as asbestosis or mesothelioma. Certain of these diseases could have a long-lasting latent period. This means it is difficult for people to spot the issue before it's late. Asbestos Identification Asbestos is a group of naturally occurring minerals that were once used in building materials as they are fire retardant, corrosion resistant and insulate. Inhaling tiny fibres of asbestos can cause health hazards. This can lead to diseases like mesothelioma and asbestosis. Symptoms of these illnesses don't appear until several years, or decades after the initial exposure. They are often mistaken for flu-like symptoms. This is why it's crucial for people to know how to identify asbestos. The most effective method to identify asbestos is through medical tests to look for lung disease. These tests usually 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 should be paired with a detailed patient history that includes the person's work, residence, and the culture of their environment. It is possible to detect asbestos in a vast assortment of building products and materials, including cement products, flooring tiles, paints, adhesives, Artex, insulation, doors, partitions and cladding. However, asbestos is difficult to detect because the fibers that pose danger are so small and light that they may easily float in the air and then be breathed in without being recognized. They don't emit any distinct smells either. If you suspect that a particular material may contain asbestos, you can collect the material as a sample. This should only be done by a trained professional, as removing asbestos is very complex and requires specialized equipment. Patch the sample with duct tape to stop the release of fibers, and take it to an asbestos analysis lab accredited by the National Voluntary Laboratory Accreditation Program (NVLAP). A list of accredited laboratories can be found on the NVLAP website. It's easy to accidentally cause harm to asbestos, and the risk of doing this is much higher for certain groups of people. Construction workers, plumbers, and electricians are all at risk of asbestos exposure when they work on renovations or maintenance. Anyone who works in these fields must take an asbestos awareness course to ensure that they are aware of the dangers and know how to take the necessary precautions. Samples to take Samples For asbestos testing or inspection, a sample of the material that is suspect is required. This sample could be taken by an asbestos consultant or a homeowner. However, it is important to ensure that you do not produce asbestos-containing dust in the air during the cleaning and collection process. The person who collects the sample is likely to require a HEPA-filtered air cleaner as well as a spray bottle filled with water, and disposable covers for protection. While performing the task, they must wear a respirator compliant with AS/NZS1716 : 2003 Respiratory protective device. It is recommended to collect samples on the day that isn't windy and shut off the cooling or heating system. This will minimize the airborne asbestos particles. When collecting the sample ensure that the area is fully closed off and that any children or pets are not allowed in. After the sample has been taken then clean up all tools and equipment with a damp cloth. Place the rag into a plastic bag and label it as contaminated waste, and dispose of it at an asbestos-free disposal facility that is licensed. Place the bag that you re-sealable with the sample inside a second plastic bag, and seal it all before marking it as asbestos waste. Place a dropsheet of plastic over the area that needs be cleaned, and then wet it down once more. This will catch any fibres that escape. Asbestos samples are typically gathered through a pump and cassette system that is pre-assembled. concord asbestos attorneys is essential to ensure that the cassette does not become overloaded with dust. This could obscure the fibres and bias the results. If the sample is located in an area that has significant levels of nonfibrous dust may be necessary to utilize smaller volumes of air. The epidemiological studies showed that short asbestos fibres can also cause mesothelioma and lung cancer. This suggests that size is not the only factor that affects the pathogenicity of asbestos fibers. Other factors like chemical property, polarization, dispersion staining, and the time required to etch are also a factor. Identifying Professionals When asbestos fibers are displaced or disturbed they can be airborne. These microscopic fibers, when inhaled, can trigger lung disease. They can cause mesothelioma or asbestosis, as well as other neurological and respiratory problems. The time of onset for many symptoms can vary from 20 to 50 years after exposure. Undisturbed asbestos does not pose a health risk, but when insulation, shingles and flooring get damaged or wear out they could release harmful fibers. This could happen in the course of a renovation or demolition project, and also in normal use of the home or aging. If you're planning to make changes to your home, ask local health or environment officials if the building contains asbestos. If asbestos is discovered in your home, you should get it checked before any work can begin by an asbestos inspector who is accredited. If you're planning to renovate an older house, ensure that any contractors you employ have the appropriate credentials. They must be able conduct an asbestos survey and report, which includes an assessment of the condition of any asbestos-containing material (ACM) and their friability. The survey should also include whether the contractor will remove or leave the ACM intact. Repairs of minor nature are possible with certain ACM and other ACMs, but only a trained professional who knows the techniques for handling asbestos safely should attempt them. No matter what type of repair is made it is essential that the area be sealed from the rest of your home. Any contaminated clothing or equipment should be put into plastic bags and marked with a warning to prevent cross-contamination. Professionals can seal ACM or cover it to stop the 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 becoming airborne. This can be done to insulated pipe or to cover old shingles. Professionals are also able to physically remove ACM. The materials are first wetted so that they can be cut with various tools without releasing dangerous fibers. The materials are then put in airtight and durable containers that are leak-proof. Removing or replacing Asbestos Asbestos is impervious to heat and corrosion. This makes it an ideal material for a myriad of products like wallboards, fireproofing insulation, and auto brakes. Asbestos is a poisonous substance that can cause respiratory issues when fibers are breathed into. These fibers can cause tissue inflammation and scarring of the lungs. This can affect breathing and cause serious health problems. Asbestos can be found in numerous parts of your home such as roof shingles, cement pipes, floor and ceiling tiles as well as joint compound that contains asbestos. Be sure to check these areas for water damage, abrasions, or tears. If the material is only slightly damaged, it may be safe to touch or disturb. However should the material be in need of repair or you plan to make changes to your home that might disturb it, consult with an asbestos professional. These experts can carry out an inspection of the visual and also take samples. They can also provide suggestions on what adjustments are required and who qualifies. It is crucial that you let experts handle your asbestos. Some of these professionals have specialized training in specific 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 learn about asbestos-related training programs that are available in your area. Be aware of companies which falsely claim they specialize in asbestos removal. These companies can be risky because they encourage unnecessary removals or do them incorrectly and increase the risk of release of harmful fibers. The American Lung Association does not endorse these companies. It is important to conduct a thorough investigation of the company before hiring an asbestos expert to ensure that they are fully insured and certified. You can ask for references from previous clients, as well as proof of insurance and accreditation. It is also recommended to check with your state or local environmental and health departments to determine the procedure that must be followed if planning to make any changes within your home.
