Asbestos is a group of naturally occurring fibrous minerals that have been or are currently used in industry due to their exceptional properties such as tensile strength, low thermal conductivity, and relative resistance to chemical attack. For these reasons, asbestos is used for insulation in buildings and as an ingredient in various products such as roofing shingles, water pipes, fire retardant coatings, and the clutch and brake pads, O-rings, and vehicle supports.Asbestos exposure also causes other diseases such as asbestosis (pulmonary fibrosis) and thickening and effusion. That is why it is good to look for an asbestos removal company in Avalon to help in eliminating it. But asbestos removal should be done fast as possible once found because it is dangerous to human health.
Asbestos began to be produced and mass-produced products from it already in the middle of the 19th century. In fact, asbestos is a mineral related to fibrous silicates (a fibrous variety of minerals of the serpentine and amphibole groups). Chrysotile asbestos in its chemical composition is magnesium hydrosilicate. They also contain iron, calcium, or sodium.
Why is asbestos a problem?
All types of asbestos are carcinogenic to humans. Exposure to asbestos causes cancer of the lungs, larynx, and ovaries, as well as mesothelioma. Currently, many people worldwide are exposed to asbestos either in the workplace or at home. Asbestos is responsible for nearly half of all occupational cancer deaths. In addition, it is estimated that several thousand annual deaths can be caused by exposure to asbestos in the home. Simultaneous exposure to tobacco smoke and asbestos fibres has also been shown to increase the risk of lung cancer significantly – and the more a person smokes, the higher the risk.
What materials can replace asbestos?
Many fibrous substitutes for chrysotile asbestos assessed by WHO pose a relatively small hazard to human health, although the carcinogenic hazard of some fibrous substitutes has been found to be high. However, numerous low-hazard non-fibrous materials can replace asbestos in various uses, such as common building materials.
- Waterjet blasting: the last resort for asbestos removal:
Typically, asbestos removal is done using low dust emission techniques such as liquid injection and spraying and manual removal. The main goal is to lower worker exposure and hinder the spread of dust. However, it may also be necessary to use more abrasive methods when removing asbestos-containing materials (AFM) in some exceptional circumstances. Blasting should only be considered as a last resort in some rare cases. A licensed demolition contractor must fully justify the use of the process. There are demolition contractors in Sydney you can turn to if you have an asbestos removal problem.
Usually, it is the customer who initiates the abrasive treatment to remove asbestos. Most customers want the building to be asbestos-free, by whatever means are needed. As a demolition contractor, you must involve the client in the decision-making process and explain the additional risks associated with asbestos removal. Together, you must consider whether the reasons for removing asbestos are worth the risks.
