Naturally occurring silicate minerals in a set of six which for their desirable physical qualities are exploited commercially is known as Asbestos. Its meaning in Greek is ‘inextinguishable’ or ‘unquenchable’. Long thin (1:20) thin fibrous crystals are present in them in their Asbestiform habit. Asbestosis which is a type of Pneumoconiosis and Mesothelioma, a rare cancer are associated with asbestos exposure, as are malignant lung cancer and other serious illnesses caused by the inhalation of asbestos fibers.
Extraction and use of asbestos, processing and manufacture of its products have been banned by the European Union since January 1, 2005. For positive identification techniques like electron microscopy, and as of today PCM/PLM and gravimetric techniques are being used. It is difficult to identify asbestos because the most hazardous and smallest fibers are limited to PM10 particulate size evaluation. Ultrafine particles are completely ignored in this evaluation.
Health hazards:
Its resistance to chemical and electrical damage and resistance to heat, average tensile strength, and sound absorption, made Asbestos increasingly popular in the 19th century amongst builders and manufacturers. Its fibers are often woven into mats or fabrics when it is used for resistance to heat and fire. In the past, it was used on hotplate wiring and the electric oven for its electrical insulation at elevated temperature. For its resistance to chemicals, flexibility, tensile strength, insulating and flame retardant properties it was also used in buildings.
The United States Environmental Protection Agency defines around six minerals as ‘Asbestos, including those belonging to the amphibole class actinolite, anthophyllite, tremolite, crocidolite and amosite as well as the serpentine class chrysotile. Between amphibole and serpentine asbestos there is an important distinction to be made, in the degree of potency. This is a health hazard when inhaled and in the chemical composition. It is important to identify asbestos in homes today. As it is a versatile material, it is very useful in the construction of residential and commercial properties. Fibers of asbestos get lodged in the lining of lungs when inhaled and are invisible to the naked eye. Such a condition leads to a cancer called Mesothelioma.
Hire a professional:
It can be a tricky task trying to identify asbestos and products containing asbestos because the fibers cannot be identified by normal sight. A professional is the right person to discover if there is asbestos in a product, as the fibers are hundred times thinner than the human hair. Avoid identifying it at home, as this can cause more danger to your family and you. A better option is to leave the product undisturbed if an asbestos containing material is discovered. A certified asbestos removal professional is the best person to get it replaced or removed.
There are good chances that some of the materials in your home may contain asbestos in some form or the other. Before the late 1970s and till the 1980s asbestos has been widely used in homes. To identify asbestos content you will have to check ingredients in a number of products. Window glazes and exterior caulking, asbestos tape or coatings around steam tubing or hot water pipes, around wood burning stoves, cement sheets or asbestos paper, door gaskets, insulation for furnaces, ceiling tiles, artificial ashes for gas fired fireplaces, vinyl sheet flooring, vinyl floor tiles, roofing and siding shingles, etc. Handling the disposal of asbestos means you are at a greater risk from airborne asbestos fibers.
Older buildings are more likely to contain asbestos in the form of corrugated or flat sheets. These have been used in roofing, ceilings, walls, and even sprayed in pipes. Many other products like roof coatings, clutch facings, asbestos cement corrugated sheets, flooring felts, disc brake pads, roll boards, industrial and commercial asbestos friction products, non roofing coatings, drum brake linings, pipeline wrap, automatic transmission components, asbestos cement shingles, mill boards, brake blocks etc. are some other products that contain asbestos.
Detailed attention required while identifying:
Detailed attention is required if you want to identify asbestos. When verifying, health risk is a factor which needs to be considered. The safest way to ensure everyone’s safety is to seek the aid of an asbestos consultant. It is best to seek aid from experts as they have the license to carry out the task, with lesser implications on health due to legal implications associated with exposure to possible asbestos containing properties. Determine if the asbestos containing materials are intact and whether the fibers are airborne once a property shows positive signs of asbestos contamination.
Check whether the property has to be encapsulated or sealed and secured or whether it has to be scrapped from the entire property. Once you identify asbestos , it is advisable to get rid of material containing asbestos at the earliest. It is important identifying asbestos in homes as exposure to its fibers is a proven and serious health risk.
