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 costly. However, exposure to airborne asbestos fibers can lead to lung diseases like mesothelioma and asbestosis.

Some of these diseases can have a long latent period. This makes it difficult to recognize an issue before it's late.

Asbestos Identification

Asbestos is a group of naturally occurring minerals that were used in building materials due to the fact that they are fire-resistant, corrosion resistant and insulate. Inhaling the microscopic fibers could cause health hazards. This can lead to the development of diseases such as asbestosis and mesothelioma. These diseases can take years, or even decades, to show their symptoms. They are often mistaken as flu-like symptoms. This is the reason it's so important for people to be aware of how to identify asbestos.

The most common way to detect asbestos is through medical tests that look for lung diseases. The tests typically consist of a physical examination, chest X-rays and lung function tests. However, asbestos-related illnesses can't be identified by these tests on their own, since they require a combination with a thorough medical history that looks at a person's work, home and their cultural surroundings.

It is possible to find asbestos in a wide range of building materials and materials that include cement products paints, floor tiles, adhesives, Artex, insulation, doors, partitions and cladding. However, asbestos case can be difficult to recognize because the fibers that pose danger are so small and light that they could easily flounder in the air and be inhaled without being recognized. They don't also emit distinct smells.

You can collect a small sample if you suspect that the substance you're looking at has asbestos. This should only be performed by a professional who is trained, as removing asbestos is very complicated and requires specialized equipment. Patch the sample using duct tape to avoid the release of fibers and send it to an asbestos analysis laboratory certified by the National Voluntary Laboratory Accreditation Program (NVLAP). The NVLAP website provides an inventory of accredited laboratories.

Certain groups of people are at greater chance of accidentally damaging asbestos. Construction workers, plumbers, and electricians are at risk of exposure to asbestos during renovations and maintenance. Anyone working in these areas should complete an asbestos awareness course to ensure that they are aware of the dangers and are aware of the appropriate precautions.

Take Samples

A sample of the suspected material is required to conduct asbestos testing or inspection. This sample can be taken by a professional asbestos consultant or by the homeowner, however caution must be taken to minimise the generation of airborne asbestos containing dust both when collecting the sample, and during cleaning up afterwards. The person who is taking the sample will typically need a HEPA-filtered air vacuum cleaner, a spray bottle of water and disposable coveralls as protection. They should wear a respirator that conforms to AS/NZS1716.2003 Respiratory protective devices while carrying out the task. It is recommended to conduct the sampling on a calm, non windy day and ensure that cooling or heating systems are off, so that there is less chance of release of any airborne asbestos particles.

When collecting the sample make sure the area is completely sealed off and that pets and children are allowed to be allowed to enter. After the sample is taken clean all tools and equipment with a damp cloth. Place the rag in the bag, label it as asbestos waste, and dispose of it at an approved asbestos disposal facility. Place the bag that is resealable and the sample in a separate plastic bag. Secure it all before declaring it asbestos waste. Clean the area with water to be cleaned up again and place a plastic drop sheet over it to collect any released fibres.

Asbestos samples are typically collected by using a pump and cassette system that is pre-assembled. It is important to ensure that the cassette is not overloaded with dust, since this could block the fibres on the filter and create an unintended bias in the outcome. If the sample is taken from an area that has high levels of dust that is non-fibrous, a smaller air volume can be used.

While the majority of studies focus on long asbestos fibers, the epidemiological studies have shown that exposure to short asbestos fibres can cause mesothelioma and lung cancer as well. This indicates that size is only one of the factors influencing the pathogenicity of asbestos fibres and that other factors such as chemical properties like polarization, dispersion staining and etching time are as well.

Identifying Professionals

When asbestos fibers are dispersed or disturbed they can be airborne. If inhaled, these microscopic fibers can cause lung diseases. These microscopic fibers can cause asbestosis or mesothelioma aswell in other neurological and respiratory diseases. The time to develop symptoms can range between 20 and 50 years after exposure.

Unaltered asbestos isn't a health hazard, but when materials like flooring, insulation, and shingles are damaged, they could release harmful fibers. This can occur in the course of a renovation or demolition project or even in normal home use or as a result of aging.

If you're planning to remodel your home, ask local health or environment officials to determine if the structure is contaminated with asbestos. If asbestos is found then it should be examined by an asbestos-certified inspector before you begin any work.

If you are renovating an older property, make sure that the contractors you hire have the appropriate credentials. They should be able supply an asbestos report and survey that includes an assessment on the condition of any ACM (asbestos-containing material) 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 certain ACM, but only a professional trained in methods for safely handling asbestos should attempt the repairs. Whatever the type of repair, the area must be isolated from the other areas of the house, 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 ACM or cover it to stop the fibers from being released into the air. 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 piping or to cover old shingles.

Professionals can also physically remove ACM. The process begins by soaking the materials in order that they can be cut or scraped using a variety of tools without releasing the dangerous fibers. The material is then placed in airtight, sturdy containers that are leakproof.

Repairing or removing Asbestos Settlement

Asbestos is invulnerable to heat and corrosion. This makes it a suitable material for thousands of products like wallboards insulation, fireproofing and auto brakes. Asbestos can be a poisonous material that can cause respiratory issues when fibers are breathed in. These fibers can cause tissue inflammation and scarring in the lungs. This could affect breathing and lead to serious health problems.

Asbestos can be found in numerous areas of the home, including floor and ceiling tiles roof shingles, exterior siding, cement pipe, Asbestos Settlement and asbestos-containing joint compound. Examine these areas for water damage, abrasions, or tears. Material that is slightly damaged may be safe as long as it's not disturbed or touched. However it is damaged or you are planning to make changes to your home that could affect it, speak with an asbestos expert.

These professionals can perform an inspection visually as well as take samples. They can also give you advice about what corrections need to be made and who is qualified to perform them. It is essential that you let experts manage your asbestos. Some of them have specific training in particular asbestos products, and only they should do corrective work on them.

You can also 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. Beware of firms that claim to be specialists in asbestos removal. These firms could be dangerous because they encourage unnecessary removals or conduct them improperly, increasing the danger of release of harmful asbestos fibers.

The American Lung Association does not endorse these companies. Before hiring an asbestos expert, it is important to conduct a thorough investigation of the company to ensure that it's certified and insured. You can also request references from previous clients and also evidence of accreditation as well as insurance coverage. It is also recommended that you check with your state or local environmental and health departments to determine what guidelines should be followed if you're planning to do any remodeling within your home.
