How to Identify Asbestos
In the last century, asbestos was used to make thousands of products stronger and more resistant to fire, and cheaper. However, exposure to asbestos-containing airborne fibers can cause lung diseases like mesothelioma or asbestosis.
Some of these diseases have a long period of latency. It is difficult to detect a problem until it's too long gone.
Asbestos Identification
Asbestos is a group of naturally occurring minerals that were previously used in building materials because they are fire-resistant and corrosion resistant, as well as insulation. Inhaling tiny fibres of asbestos can create health risks. This can lead to diseases such as asbestosis and mesothelioma. The symptoms of these illnesses don't appear until several years, or years after the initial exposure. They are often misinterpreted as flu-like symptoms. It's vital that people understand how to recognize asbestos.
The most commonly used method to identify asbestos is through medical tests to look for lung disease. These tests include physical examinations, chest X-rays, and lung function tests. However, asbestos-related ailments can't be diagnosed with these tests on their own, since they require a combination with a thorough patient history that includes the person's work, home and the cultural context.
It's possible to find asbestos in a wide variety of building products and materials that include cement products, paints, floor tiles, adhesives, Artex, insulation, doors, partitions and cladding. However, asbestos is difficult to recognize since the dangerous fibers are so small and light that they can easily flounder in the air and be inhaled without being recognized. They don't have distinct smells either.
You can collect a small sample if you suspect that a material contains asbestos. It is essential that you only use a professional to remove asbestos since it's an extremely complex process that requires special equipment. Patch the sample with duct tape to stop 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 labs.
It's very easy to accidentally disturb asbestos and the danger of doing so is more pronounced for certain groups of people. Construction workers, plumbers, and electricians are at risk of exposure to asbestos during maintenance and renovations. It's a good idea for those who work in these fields to complete an asbestos awareness course to ensure they are aware of the risks and can make the right precautions.
Take Samples
A sample of the suspected material is required to conduct asbestos testing or inspection. The sample could be taken by an asbestos expert or a homeowner. However it is crucial to be careful not to generate airborne asbestos-containing dust during the taking and cleaning. The person taking the sample will typically need an air vacuum cleaner with HEPA filters and a spray bottle of water and disposable coveralls as protection. They must also wear a respirator which complies with AS/NZS1716:2003 Respiratory protective devices when performing the task. It is best to collect samples on a day that is not windy and shut off the cooling or heating system. This will reduce the airborne asbestos particles.
When collecting the sample make sure that the area is closed off and that any children or pets are not permitted in. After the sample has been taken clean all tools and equipment with a damp cloth. Place milpitas asbestos lawyer in an unmarked plastic bag, label it as asbestos waste and dispose of it in an asbestos-free facility that is approved by the government. Place the resealable bag and the sample inside a different plastic bag, then seal it before declaring it asbestos waste. Clean the area with water to be cleaned once again, and place a plastic drop sheet over it to catch any fibres that are released.
Asbestos samples are typically gathered with the help of a pump and cassette system that is pre-assembled. It is crucial to ensure that the cassette is not overloaded with dust, as this may obscure the fibres on the filter and create distortion in the result. If the sample is being taken from an area that has high amounts of dust that is not fibrous a smaller volume of air can be utilized.
The epidemiological studies showed that asbestos fibres of short length can also trigger mesothelioma or lung cancer. This proves that size isn't the only factor that affects the pathogenicity of asbestos fibers. Other parameters such as chemical property, polarization and dispersion staining, and the time to etch are also involved.
Identifying Professionals
Asbestos fibres can become airborne when they are disturbed or spewed out. These microscopic fibers, once inhaled, can trigger lung diseases. These can lead to mesothelioma, asbestosis, or other neurological and respiratory issues. The time between onset and recurrence of symptoms can be anywhere from 20 to 50 years after exposure.
Unaffected asbestos is not an health risk, however when the materials used for insulation, shingles, or flooring get damaged or wear out, they can release the harmful fibers. This can happen during a renovation or demolition project, or during normal home use or as the house ages.
If you're planning to renovate your home, ask local health or environmental officials if the building contains asbestos. If any asbestos-containing material is discovered, have it inspected by an asbestos inspector who is accredited before any work can begin.
When you're planning to renovate an older home ensure that the contractors you hire have the proper credentials. They should be able to provide an asbestos report and survey that contains an assessment on the condition of any ACM (asbestos-containing material) and their brittleness. The survey should also indicate whether the contractor will take away or leave the ACM intact.
Minor repairs are possible on some ACM. However, only a professional certified in the safe handling of asbestos should attempt these. No matter what type of repair you make the area must be protected from the rest of your home. Any clothing or equipment should be put in plastic bags and labeled with a warning to avoid cross-contamination.
Professionals can seal or cover ACM to stop it from dispersing fibers into the atmosphere. Sealing (encapsulation) involves treating the material with a chemical that binds or covers the fibers to prevent them from being airborne. This can be done on insulated pipes or to cover old shingles.
Professionals can also physically remove ACM. The materials are initially soaked in order to enable them to be cut using a variety of tools without releasing dangerous fibers. The material is then put in airtight, sturdy containers that are leakproof.
Removing or repairing Asbestos
Asbestos is impervious to heat and corrosion. This makes it a suitable material for a myriad of products like wallboards as well as fireproofing insulation and auto brakes. Asbestos is a toxic substance that can cause respiratory issues when fibers inhaled. Typically, these fibers get stuck in the lungs, and can cause tissue inflammation and scarring which can make breathing difficult and lead to serious health issues.
Asbestos is found in numerous areas of the home, including ceiling and floor tiles roofing shingles exterior siding, cement pipe, and asbestos-containing joint compound. It is essential to examine these areas on a regular basis for damage, tears, or damage. If the material is slightly damaged, it may be safe to touch it or disturb it. If the material must be repaired or you are planning to make changes to your home that could affect it, then consult with an asbestos professional.
These experts can carry out an inspection by visuals and also take samples. They can also offer suggestions on what adjustments are required and who qualifies. It is important that you let the experts manage your asbestos. Some of them are trained in specific products, and they're the only ones who should perform corrective work on them.
You should also contact your local or State Health Department or Regional Office of the U.S. Environmental Protection Agency to find out about asbestos training programs offered in your area. Be aware that there are firms who falsely claim to specialize in asbestos removal. These firms could be dangerous because they encourage unnecessary removals or make them in a way that isn't properly done, increasing the danger 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 professional to ensure it is properly insured and certified. You can also request references from former clients, along with evidence of accreditation as well as insurance coverage. It is also recommended that you contact your state or local environmental and health agencies to find out what procedures must be followed if planning to make any changes in your home.
