How to Identify Asbestos
In the last century asbestos was used in a variety of products, to make them stronger, more fire-resistant and less costly. Exposure to asbestos fibers within the air can lead to lung diseases like mesothelioma or asbestosis.
Some of these diseases have a long time of latency. This makes it difficult for people to spot the problem before it's too late.
Asbestos Identification
Asbestos is a class of naturally occurring minerals that were once popular in building materials due to the fact that they are fire-resistant and corrosion resistant, as well as insulation. Inhaling the microscopic fibres can pose health risks. This often causes diseases like asbestosis and mesothelioma. These illnesses can take years or even decades to display their symptoms. They are often mistaken as flu-like symptoms. This is why it's crucial for people to know how to recognize asbestos.
Medical tests that check for lung diseases are the most common way to find asbestos. These tests include a physical exam or chest X-rays as well as lung function tests. However, asbestos-related ailments can't be diagnosed using these tests alone, as they must be paired with a thorough patient history that examines a person's work, home and cultural environment.
It is possible to find asbestos in a wide variety of building products and materials such as cement products, paints, floor tiles, adhesives, Artex, insulation, doors, partitions and cladding. However, asbestos can be difficult to recognize because the dangerous fibers are so tiny and light that they could easily float in the air and breathed in without being observed. They don't have any distinct smells either.
You can collect a small sample if you suspect that a material contains asbestos. This should only be done by a trained professional, since removing asbestos is extremely complex and requires special equipment. Patch the sample with duct tape to prevent the release of fibers, and take it to an asbestos analysis laboratory accredited by the National Voluntary Laboratory Accreditation Program (NVLAP). A list of laboratories can be found on the NVLAP web site.
Certain categories of people are at a greater risk of accidentally disturbing asbestos. These include construction workers, plumbers and electricians, since they are more likely to encounter asbestos-containing products during renovations and maintenance. It's recommended for anyone working in these fields to complete an asbestos awareness course so that they understand the dangers and take the correct precautions.
Take Samples
A sample of the suspected material is required for asbestos testing or inspection. This sample can either be taken by an asbestos consultant or a homeowner. However, it is important to ensure that you don't create dust containing asbestos that is airborne during the collection and cleaning process. Typically, the person taking the sample must have a HEPA-filtered vacuum cleaner, an water spray bottle and disposable coveralls to protect themselves. When performing the task, they must wear a respirator compliant with AS/NZS1716: 2003 Respiratory protective device. It is best to take samples on an occasion that isn't windy and shut off the cooling or heating system. This will limit the risk of airborne asbestos particles.
When you collect the sample, make sure that the area is sealed off and that no children or pets can enter. Wet down the area to be sampled using the help of a damp rag. Then, clean all equipment and tools that were used after the sample has been completed. Place the damp rag in a bag and label it as contaminated waste, and dispose of it at an asbestos disposal facility that is approved. Place the bag that you re-sealable with the sample in another plastic bag, and seal it up before marking it as asbestos waste. Place a dropsheet of plastic over the area that needs to be cleaned. Then, wet it down again. indiana asbestos lawyer will capture any fibres that escape.
Asbestos is typically filtered using a pre-assembled pump and cassette system. It is crucial to ensure that the cassette does not get stuffed with dust. This could obscure the fibres and alter the results. If the sample was taken in an area where there are high levels of nonfibrous dust might be necessary to use smaller volumes of air.
The epidemiological studies showed that asbestos fibres with a shorter length could also cause mesothelioma, or lung cancer. This indicates that size is only one factor that influences the pathogenicity of asbestos fibers and that other factors such as chemical properties such as polarization, dispersion staining and etching times are also involved.
Identifying Professionals
When asbestos fibers are dispersed or disturbed they can airborne. If inhaled, the microscopic fibers may cause lung disease. They could cause mesothelioma, asbestosis or other neurological and respiratory problems. The time between onset and recurrence of symptoms can take anywhere from 20 to 50 years after exposure.
Unaltered asbestos isn't hazardous to health, but when materials like flooring, shingles, or insulation are damaged, they could release harmful fibers. This could happen in the course of a renovation or demolition project, as well as when you use your home for normal activities or aging.
If you are planning to redesign your home, inquire with your local health or environmental officials if the building contains asbestos. If asbestos is found in your home, you must get it checked before any work is started by an asbestos inspector who is accredited.
If you are renovating an older home, make sure that any contractors you hire have the appropriate credentials. They should be able to conduct an asbestos survey and report which includes an assessment of the condition and condition of any asbestos-containing material (ACM) and their ability to withstand friability. The survey should also indicate whether the contractor plans to remove or leave the ACM intact.
Minor repairs might be feasible on certain ACM and other ACMs, but only a professional trained in ways to safely handle asbestos should attempt the repairs. Whatever repair is made, the area must be sealed from the rest of your home. Any clothing or equipment should be placed into plastic bags and marked with a warning in order to prevent cross-contamination.
Professionals can seal ACM or cover it to prevent fibers from being released into the environment. Sealing (encapsulation) involves treating the material with a chemical that binds or coats fibers to prevent them from being airborne. This can be done on insulated piping, or to cover old shingles.
Professionals can also physically remove ACM from a structure. The process begins by soaking the materials so they can be cut or scraped using various tools without releasing dangerous 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 makes it an ideal material for a myriad of products including wallboards, fireproofing insulation, and auto brakes. Asbestos is a toxic substance that can cause respiratory issues when fibers are inhaled. Typically, these fibers become trapped in the lungs. They could cause tissue inflammation and scarring, which can hinder breathing and lead to serious health issues.
Asbestos can be present in a variety of places within an apartment, such as ceiling and floor tiles, roof shingles, exterior siding, cement pipe, and asbestos-containing joint compound. 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 even disturb. If the material must be repaired or replaced, or you are planning to make changes to your home that could cause disturbance to it, then consult an asbestos expert.
They can conduct an inspection visually and collect samples. They can also provide advice about what corrections need to be done and who is qualified to make them. It is important that you only have the experts manage your asbestos. Some of these professionals have specialized training in specific products, and only they should do corrective 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 training programs offered in your area. Be wary of companies that claim to be experts in asbestos removal. These firms pose a threat since they promote or perform unneeded removals, which increase the possibility of harmful asbestos fibers being released.
The American Lung Association does NOT endorse these companies. Before hiring an asbestos specialist it is essential to conduct a thorough investigation of the company to ensure it's accredited and insured. You can also ask for references from previous clients along with evidence of accreditation and insurance coverage. It is also recommended to contact your state or local health and environmental authorities to find out what procedures should be followed when planning to perform any type of remodeling at home.
