How to Identify Asbestos

During the past century, asbestos was used to make a myriad of products stronger, more resistant to fire, and less expensive. However, exposure to airborne asbestos fibers could cause lung diseases like mesothelioma and asbestosis.

Some of these diseases have a long period of latency. It can be difficult to recognize a problem until it's too far gone.

Identifying Asbestos

Asbestos is a class of naturally occurring minerals that were used in building materials since they are fire-resistant and corrosion resistant, as well as an insulator. Inhaling tiny fibres of asbestos can cause health hazards. This can lead to the development of diseases such as asbestosis and mesothelioma. The symptoms of these diseases do not appear until years, even decades after initial exposure. They are often mistaken for flu-like symptoms. It's essential to know how to identify asbestos.

Medical tests that test for lung disease are the most frequent method to identify asbestos. These tests include physical exams, chest X rays and lung function tests. However, asbestos-related ailments can't be diagnosed using these tests alone, as they must be paired with a thorough medical history that includes the person's work, home and their cultural surroundings.

It is possible to detect asbestos in a vast variety of building products and materials that include cement products floor tiles, paints adhesives, Artex, insulation, doors, partitions, and cladding. Asbestos is difficult to spot because the fibers are tiny and light. They are able to easily glide through the air, and inhale without anyone not even realizing. They don't also emit distinctive smells.

You can take a tiny sample if you suspect the substance you're looking at has asbestos. 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 prevent the release of fibers, and send it to an asbestos analysis laboratory that is accredited by the National Voluntary Laboratory Accreditation Program (NVLAP). A list of laboratories is available on the NVLAP website.

It is very easy to accidentally disturb asbestos, and the risk of doing so is much higher for certain groups of people. These include plumbers, construction workers and electricians as they are likely to see asbestos-containing materials in maintenance and renovations. It's a good idea for all workers in these fields to complete an Asbestos Settlement awareness training course so that they understand 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 can be collected by an asbestos expert or by the homeowner, however caution must be taken to reduce the amount of asbestos-containing dust in the air during the process of collecting the sample as well as when cleaning up after. Typically, the person who is taking the sample should carry a HEPA-filtered vacuum cleaner a water spray bottle, and disposable coveralls to protect themselves. While performing the task, they should wear a respirator in accordance with AS/NZS1716 : 2003 Respiratory protection device. It is best to collect samples on a day that is not windy and shut off the heating or cooling system. This will minimize the airborne asbestos particles.

When collecting the sample, make sure the area is completely sealed and that no pets or children can be allowed to enter. After the sample has been collected then clean up all instruments and equipment using a damp cloth. Place the rag 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 in a second plastic bag. Then, seal it all up before declaring it asbestos waste. Wet down the area to be cleaned a second time and place a drop sheet over it to catch any released fibres.

Asbestos is typically filtered using a pre-assembled pump as well as a cassette system. It is vital that the cassette does not get overloaded with dust, since this could block the fibres on the filter and cause an unintended bias in the outcome. If the sample was taken in an area that has significant levels of nonfibrous dust may be necessary to use less air.

While most research is focused on long asbestos fibers but epidemiological studies have found that exposure to short asbestos fibres can trigger mesothelioma and lung cancer as well. This suggests that size isn't the only one of the variables that influence the pathogenicity of asbestos fibres and that other parameters like chemical properties, polarization, dispersion staining and etching times are as well.

Identifying Professionals

Asbestos fibers can be airborne when they are disturbed or spread. These microscopic fibers when inhaled, may cause lung diseases. They could cause mesothelioma and asbestosis as well as other respiratory and neurological problems. The time between onset and recurrence of symptoms can vary from 20 to 50 years after exposure.

Unaltered asbestos is not hazardous to health, but when the materials like flooring, insulation, and shingles are damaged, they might release harmful fibers. This can occur during a demolition or renovation project, or even during normal home use or as a result of aging.

If you are planning to renovate your home, inquire with your local health or environmental department whether the building has asbestos. If asbestos is found, have it inspected by an asbestos-certified inspector before any work can begin.

If you are renovating an older house ensure that the contractors you employ have the required credentials. They should be able to conduct an asbestos survey and report that contains an assessment of the state of any asbestos-containing material (ACM) and their brittleness. The survey should also indicate the contractor's intention to remove or leave the ACM intact.

Minor repairs can be made on some ACM. However only a professional skilled in asbestos safety should attempt these. Whatever the type of repair, the affected area should be sealed off from the rest of the home and any equipment or clothing should be placed in plastic bags and labeled with a warning in order to prevent cross-contamination.

Professionals can seal or cover 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 keep them from becoming airborne. This can be done to insulated pipes or to cover old shingles.

Professionals can also physically remove ACM. The process begins by wetting the materials so that they can be scraped or cut with a variety of tools without releasing the dangerous fibers. Then they place the material in durable, leak-proof air-tight containers to ensure safe disposal.

Repairing or removing Asbestos

Asbestos is invulnerable to heat and corrosion, which has made it an extremely useful component in many different products like wallboard, fireproofing insulation and auto brakes. But asbestos is also an irritant that can cause respiratory problems if fibers are inhaled. These fibers can cause tissue inflammation and scarring of the lungs, which could affect breathing and cause serious health issues.

Asbestos can be found in numerous areas of homes, asbestos settlement including ceiling and floor tiles, roofing shingles, exterior siding, cement pipe and asbestos-containing joint compound. Examine these areas for water damage or abrasions. Material that is slightly damaged may be safe if it is not disturbed or touched. If the material has to be repaired, or you're planning to make changes to your home that could cause disturbance to it, then consult an asbestos compensation expert.

They can conduct an inspection of the visuals and take samples. They can also give you advice on what adjustments need to be made and asbestos settlement who is qualified to carry out them. It is recommended that only these professionals handle asbestos. They are educated in specific products and should only be allowed to correct them.

In addition to consulting an asbestos expert who is trained and contacting your state or local health department or regional office of the U.S. Environmental Protection Agency for information about asbestos-related training programs in your area. Beware of firms who claim to be experts in asbestos removal. These companies can be risky because they encourage unnecessary removals or conduct them improperly which increases the risk of the release of harmful fibers.

The American Lung Association does NOT endorse these companies. It is crucial to do your research thoroughly before hiring an asbestos expert to ensure it is properly certified and insured. You can also request references from past clients, as along with proof of insurance and accreditation. It is also recommended that you contact your state or local environmental and health agencies to determine the procedure that should be followed if you're planning to perform any type of remodeling at home.
