How to Identify Asbestos
Over the course of the last century, asbestos was used in a myriad of products to make them stronger, more fire-resistant and less expensive. But exposure to asbestos in the air fibers can lead to lung diseases like mesothelioma and asbestosis.
Some of these diseases have a lengthy latency time. This makes it difficult to spot the problem before it's too late.
Asbestos Identification
Asbestos can be described as a variety of minerals that are naturally occurring. They were once utilized in building materials due to their corrosion-resistant, fireproof and insulation properties. Inhaling the microscopic fibres can cause health hazards. This often causes diseases like asbestosis and mesothelioma. These illnesses can take years, or even decades, to display their symptoms. They are often misinterpreted as flu-like symptoms. It's essential to know how to identify the asbestos.
Tests for medical conditions that detect lung disease are the most common way to find asbestos. These tests usually consist of physical examinations or chest Xrays as well as tests for pulmonary function. These tests aren't enough to determine the presence of asbestos-related illnesses. They must be combined with a detailed patient history which includes information about a person's job, home, and cultural environment.
It is possible to find asbestos in a broad range of building materials 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 may easily float in the air and breathed in without being recognized. They don't have distinct smells either.
If you suspect that a particular material could contain asbestos, you can take an atom of it. It is important that you only use a professional to remove asbestos, as it is complicated and requires special equipment. Patch the sample with duct tape in order 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 accredited laboratories can be found on the NVLAP web site.
Certain groups of people are at a greater chance of accidentally damaging asbestos. These include plumbers, construction workers and electricians, because they are likely to see asbestos-containing items during maintenance and renovations. Anyone working in these fields must take an asbestos awareness course to ensure that they are aware of the dangers and how to take the right precautions.
Take Samples
To conduct asbestos testing or an inspection, a sample from the suspect material is needed. This sample can be taken by an asbestos attorney expert or by the homeowner, however caution must be taken to reduce the amount of asbestos-containing dust in the air throughout the collection of the sample as well as when cleaning up afterwards. The person taking the sample will normally require a HEPA-filtered air cleaner and a spray bottle of water, and disposable covers for protection. They must wear a respirator that complies with AS/NZS1716:2003 Respiratory protective devices when performing the task. It is recommended to collect samples on a day that is not windy, and then shut off the heating or cooling system. This will reduce the airborne asbestos particles.
When collecting the sample make sure that the area is fully sealed off and that pets or children aren't allowed into the. After the sample has been taken then clean up all instruments and equipment using a damp cloth. Place the rag into 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 container and the sample inside a second plastic bag. Secure it all before declaring it asbestos waste. Place a dropsheet of plastic over the area that needs be cleaned, and then wet it again. This will collect any fibres that escape.
Asbestos is usually collected using an already-assembled pump and cassette system. It is crucial that the cassette isn't filled with dust since this could block the fibres of the filter and create distortion in the result. If the sample is collected in an area with high levels of dust that is non-fibrous, smaller volumes of air can be utilized.
The epidemiological studies showed that short asbestos fibres could also cause mesothelioma, or lung cancer. This shows that size is not the only factor in determining the pathogenicity of asbestos fibers. Other factors like chemical property, polarization and dispersion staining, as well as the time of etching are also important.
Identifying Professionals
When asbestos fibers are spread or disturbed they can be airborne. These tiny fibers, if inhaled, can trigger lung diseases. These can lead to mesothelioma or asbestosis, as well as other neurological and respiratory issues. The time to develop symptoms can vary between 20 and 50 years after exposure.
Unaltered asbestos isn't a health hazard, but when insulation, shingles and flooring are damaged, they can release harmful fibers. This could happen in the course of a renovation or demolition project or even during normal home usage or the aging process.
If you plan on remodeling your home, consult local environmental or health officials to determine if the structure has asbestos-containing materials. If any asbestos-containing material is discovered then it should be examined by an accredited asbestos inspector prior to any work being started.
When you're planning to renovate an older home, make sure any contractors you hire have proper qualifications. They should be able to provide an asbestos survey and report that contains an evaluation of the 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 are possible on certain ACM. However only a professional certified in asbestos safety should attempt these. Whatever the type of repair, the area must be isolated from the surrounding area and any equipment or clothing should be put in plastic bags and labeled 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) is also referred to as encapsulation, involves treating the material in a way that binds and covers the fibers so they don't become airborne. This can be done on insulated piping, or to cover old shingles.
Professionals can also physically remove ACM from a structure. The materials are first soaked so that they can be cut using various tools without releasing harmful fibers. The materials are then placed in airtight, tough containers that are leak-proof.
Repairing or Removing Asbestos
Asbestos is resistant to heat and corrosion and has been an extremely useful material for hundreds of products, including wallboard materials, fireproofing insulation and auto brakes. Asbestos can be a poisonous material that can cause respiratory problems when fibers are inhaled. Typically, these fibers become trapped in the lungs and may cause tissue inflammation and scarring which can cause breathing problems and cause serious health problems.
Asbestos can be found in many areas of a home, including floor and ceiling tiles, roof shingles exterior siding, asbestos cement pipe and asbestos-containing joint compound. It is important to inspect these areas on a regular basis for damage, tears, or damage. If the material is only slightly damaged, it could be safe to touch or even disturb. However when the material is in need of repair or you are planning to make changes to your home that could disturb it, you need to consult an asbestos professional.
They can conduct an inspection by visuals and also take samples. They can also give you information on what changes are required and who qualifies. It is best to let experts handle asbestos. These professionals have been trained in specific asbestos products and should only be allowed to correct them.
It is also recommended to contact your state's local Health Department or Regional Office of the U.S. Environmental Protection Agency to find out about asbestos training programs offered in your area. Beware of companies that claim to be experts in asbestos removal. These companies pose a risk because they encourage or carry out 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 professional, it is important to research the company thoroughly to ensure that it is certified and insured. You can also request references from past clients, and also evidence of accreditation as well as insurance coverage. It is also recommended to check with your state or local health and environmental authorities to determine what guidelines should be followed when planning to make any changes in your home.
