Asbestos was used in the last century on a large scale. This had to do with the fact that the very positive properties of asbestos (including fire-resistant, moisture-repellent and low-wear) were very important in many situations.
It was only later that it became known that asbestos was also extremely harmful to health, which meant that the material was not be used since 1990 onwards. However, since it has been used so frequently, it is still present in many different places, both in buildings, on the ground and in loose products.
The origin of asbestos
Asbestos is a collective name for various minerals, which are composed of microscopic, needle-shaped fibres.
Asbestos was known for a long time because of its numerous positive properties: it has a high strength, is wear-resistant, insulating, lime, acid and heat resistant and is also cheap. For this reason, asbestos-containing materials have often been used in the past, for example in buildings and apartments. The most widely used species are white asbestos (chrysotile), blue asbestos (crocidolite), and brown asbestos (amosite).
Friable and non-friable asbestos
Asbestos products can be divided into two categories: friable and non-friable (also referred to as bonded asbestos). Non-friable asbestos materials are firmly bonded, the fibres of which are firmly anchored in the carrier material. Firmly bound asbestos is safe as long as the material is not subjected to wear and is not processed or disposed of improperly. Friable asbestos materials are materials containing asbestos, in which the fibres are not or hardly bonded to a carrier material. If the asbestos is not firmly bonded, the fibres can easily be released.
Because of its special properties, asbestos has been processed in numerous products. There are about 3,000 products known to contain asbestos. The following is a list of the most important asbestos-containing materials and products.
Bonded asbestos products
- Hard asbestos-containing vinyl boards, especially in toilets and kitchens.
- Asbestos cement, mainly as roofing (corrugated boards, shingle boards), façade, cavity and window sill coverings, wall elements, ventilation ducts and exhaust gas ducts, gas, water and sewer pipes, as well as in flower boxes, etc. (when asbestos cement is weathered, it is no longer a bonded one).
- Asbestos in filling compound, bitumen, topcoats, architectural paints, adhesives and (as reinforcement) in plastics.
- Asbestos in disc brake blocks, clutch discs and brake linings of cars, trucks and trains (however, fibres are freed from this material by the type of application).
Friable asbestos products
This also includes products that are easily damaged or rapidly age, causing fibres to dissolve.
- Asbestos as an insulating layer in and around process plants, industrial furnaces, insulated pipes and vessels, boilers and pipes, trains and ships, etc.
- Asbestos paper and felt as a mould protection underlay for floor coverings (linoleum).
- Asbestos paper and felt as a sealing material in older electrical appliances such as bread toasters, hairdryers and electric ovens and, for example, in theatrical venues.
- Spray asbestos (very loosely bonded fibres), as a fire-resistant and / or sound-absorbing layer, e.g. for supporting steel structures and in ceilings of public buildings such as theatres, swimming pools and car parks.
- Asbestos fabrics, especially in fire protection clothing and curtains, ironing board covers, electric cables, gaskets and cable connections.
- Fireproof asbestos panels, especially under central heating boilers, in walls of heating enclosures, fuse boxes, in ceilings, stairs, etc.
- Asbestos rope in fume hoods on chimneys, conductions, masonry, pipe insulation, joints, slits and frames.
The items listed below are known to contain asbestos
- Gas, plumbing and sewer pipes (outside a building, in a building they are part of it).
- Industrial installations and pipelines (in certain cases it can also be a building).
- Heaters (if they are connected to a building, they are not an independent object, but are part of the building).
- Cement flower boxes.
- Asbestos cement wall panels (no longer attached to buildings).
- Older household appliances in which heat development occurs, such as hairdryer, bread toaster, etc.
- Older holding plates.
- Mopeds, cars, trucks and ships.
- Half-way), provided that they are not on an overpass or similar (the road of an overpass is part of a structure).
The analysis asbestos suspected materials
Would you like to know about the presence of asbestos in a particular material? Asbestos is often difficult to detect with the naked eye. In this case, a safe examination can only be carried out in an accredited laboratory.
Nevertheless, since the analysis is performed on the samples of suspected materials, the sampling process must also be performed by a licensed assessor to prevent any accidental exposure during the sample collection. The analysis time may vary, depends on the number of samples being analysed and the analysis method being used. For example if you live in Western Australia, price will be different to take one time asbestos removal Perth services for your property if we compare it with NSW rates. That why i suggest you discussing about this with expert that will help you find cheapest, nearest and honest services they can found.
NOTE: Never try to use a DIY asbestos testing package if you don’t have sufficient knowledge to do a secure sampling process. It would be better and highly recommended to leave the task to someone who has obtained a full set of skills in handling asbestos.
