How to Identify Asbestos
During the last century, asbestos was used in a variety of products, to make them more durable, fire resistant and less costly. The exposure to asbestos fibers in the air can trigger lung disease such as asbestosis or mesothelioma.
Some of these diseases have a long latency period. It can be difficult to recognize an issue until it's long gone.
Asbestos Identification
Asbestos is a range of naturally occurring minerals. They were previously used in building materials because of their anti-corrosive, fire-proof and insulation properties. It can, however, cause health hazards when the microscopic fibers are breathed in. This can lead to the development of diseases such as mesothelioma or asbestosis. These diseases can take a long time, or even decades, to display their symptoms. They are often mistaken as flu-like symptoms. This is why it's essential for people to be aware of how to recognize asbestos.
The most effective method to detect asbestos is by medical tests that check for lung disease. These tests typically include physical examinations including chest X-rays, pulmonary function tests. However, asbestos-related illnesses aren't identified by these tests alone, as they require a combination with a thorough patient history that examines a person's work, home and social environment.
It is possible to discover asbestos in a diverse assortment of building products and materials such as cement, floor tiles, paints adhesives, Artex, insulation, doors, partitions and cladding. However, asbestos can be difficult to detect because the dangerous fibers are so tiny and light that they may easily flounder in the air and be inhaled without being noticed. They also don't emit any distinctive smells.
If you suspect a material might contain asbestos, you can collect the material as a sample. This should only be done by a professional who is trained, since removing asbestos is extremely complicated and requires specialized equipment. Patch the sample with duct tape to stop the release of fibers, and take it to an asbestos analysis laboratory certified by the National Voluntary Laboratory Accreditation Program (NVLAP). A list of accredited laboratories can be found on the NVLAP web site.
Certain categories of people are at a greater chance of accidentally damaging asbestos. This includes plumbers, construction workers, and electricians as they are likely to see asbestos-containing products during maintenance and renovations. It is a good idea for those who work in these areas to complete an asbestos awareness training course to ensure they are aware of the dangers and are able to use the proper precautions.
Samples to 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 do not generate airborne asbestos-containing dust during the cleaning and collection process. Typically the person taking the sample should have a HEPA-filtered vacuum cleaner, a water spray bottle and disposable coveralls to protect themselves. They must wear a respirator that is compliant with AS/NZS1716:2003 Respiratory protection devices while carrying out the task. It is best to take samples on the day that isn't too windy. Also, turn off jersey city asbestos lawyer or heating system. This will help reduce the exposure of asbestos-containing airborne particles.
When you collect the sample, make sure that the area is sealed off and that pets and children are allowed to access the. Clean the area to be sampled using a damp rag, and clean the tools and equipment utilized after the sample is completed. Place the rag in a plastic bag and label it as contaminated waste and dispose of it at an asbestos-free disposal facility that is licensed. Place the resealable bag along with the sample into a second plastic bag. Seal it all together before marking it as asbestos waste. Wet down the area to be cleaned up again, and place a plastic drop sheet over it to capture any fibres that are released.
Asbestos is typically filtered using an already-assembled pump and cassette system. It is crucial to ensure that the cassette doesn't get stuffed with dust. This could obscure fibers and distort results. If the sample is being taken in an area with high levels of dust that is non-fibrous, a smaller air volume can be utilized.
While most testing focuses on asbestos fibers that are long but epidemiological studies have proven that exposure to short asbestos fibers may cause mesothelioma or lung cancer too. This indicates that size is only one of the factors that affect asbestos fibers' pathogenicity and that other parameters like chemical properties such as dispersion staining, polarization and etching times are also involved.
Identifying Professionals
Asbestos fibers can become airborne when they are disturbed or dispersed. When inhaled, these microscopic fibers could cause lung disease. These microscopic fibers may cause asbestosis or mesothelioma aswell as other respiratory and neurological diseases. Many symptoms may manifest within 20 to 50 years.
Unaffected asbestos is not a health risk, but when insulation, shingles and flooring are damaged or deteriorate and release harmful fibers. This can occur when you are working on a renovation or demolition project or even in regular home usage or aging.
If you plan on remodeling your home, check with local officials from the environmental or health department to determine if the building contains asbestos-containing materials. If asbestos is found in your home, you must have it inspected before any work is started by an accredited asbestos inspector.
If you are renovating an older house be sure that any contractors you employ have the proper qualifications. They should be able provide 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 the contractor's intention to remove or leave the ACM intact.
Minor repairs may be possible on some ACM and other ACMs, but only a professional with experience in techniques for handling asbestos safely should attempt the repairs. No matter what type of repair is made the area should be protected from the rest of your home. Any contaminated clothing or equipment should be put into plastic bags and labeled with a warning to prevent cross-contamination.
Professionals can cover or seal ACM to stop it from releasing fibers into the environment. Sealing (encapsulation) involves treating the material with a chemical that binds or coats fibers to prevent them from becoming airborne. This can be done on insulated pipes, or to cover old shingles.
Professionals can also physically remove ACM from a building. This process begins by wetting the materials in order that they can be cut or scraped using different tools without releasing the hazardous fibers. The material is then placed in airtight, tough containers that are leak-proof.
Repairing or removing Asbestos
Asbestos is abrasive to heat and corrosion. This makes it a great product for thousands of uses like wallboards insulation, fireproofing and auto brakes. But asbestos is also an irritant that can cause respiratory issues when the fibers are inhaled. In most cases, these fibers end up trapped in the lungs. They could cause tissue inflammation and scarring which can make breathing difficult and cause serious health issues.
Asbestos is present in a variety of places within an apartment, such as floor and ceiling tiles, roof shingles, exterior siding, cement pipe, and asbestos-containing joint compound. Examine these areas for water damage or abrasions. If the material is slighty damaged, it might be safe to touch or move. However, if the material is damaged or you plan to make changes to your home that could affect it, you need to seek out an asbestos expert.
These experts can perform an inspection of the visual and also take samples. They can also provide guidance on the corrective measures needed and who is qualified. Only professionals handle asbestos. They are educated in specific products and should be allowed to correct them.
In addition to consulting with a trained asbestos professional It is also recommended to contact your state or local health department or regional office of the U.S. Environmental Protection Agency for more information on asbestos training programs in your region. Be aware of firms who claim to be experts in asbestos removal. These firms can be dangerous because they encourage unnecessary removals or do them incorrectly, increasing the danger of release of harmful asbestos fibers.
The American Lung Association does NOT endorse these companies. Before hiring an asbestos specialist, it is important to investigate the company thoroughly to ensure that it is certified and insured. You can also request references from past clients as well as proofs of insurance coverage and accreditation. It is also recommended to contact your state or local environmental and health agencies to determine what guidelines must be followed if planning to make any changes in your home.
