Bonded (Class B) asbestos is less immediately dangerous than Class A and is part of a fibre-cement product. Clumps of mined asbestos can be broken down in to loose fibres or fibre bundles, and can be mixed with other materials, such as cement, to produce a variety of building products. One factor in the lack of public education and understanding may be the perception that asbestos is a disease of the past: many current asbestos-related deaths are due to exposure that occurred before the 1980s, when strict regulations in developed countries began to bite. Increasing numbers of mortgage lenders and conveyance solicitors are advising prospective buyers to obtain Specialist Reports on Asbestos prior to exchange of contracts.
Although rarely discussed, exposure to toxic fumes in the workplace or environmental toxins in the air contribute to a significant number of deaths from lung cancer. Asbestos products were widely manufactured and used for the first three quarters of the twentieth century, in spite of the fact that the manufacturers knew the health risks. When renovating or working in and around homes, if in doubt assume asbestos materials are present and take every precaution. Because of its insulating properties and resistance to heat, asbestos was also used aboard many naval ships.
Products that contain asbestos were once used because they were cheap, durable and would resist the effects of water and fire. Additionally, loss of appetite, fatigue, unusual losses of weight are three symptoms, which are indicative of lung cancer. When contracting out the work it is advisable to use two different services; one to do the inspections and another to do the actual containment or removal work.
The presence of asbestos in home building materials generally does not pose a health risk unless the material is broken, deteriorating or disturbed in such a way that airborne asbestos fibres are produced. The disaster recovery planning prepared by your state and territory government regularly includes contingencies and funding to clean up asbestos following an emergency. Where a laboratory outside Australia is engaged, it must be made clear that any level of asbestos detected is noted in the report.
The U.S. Environmental Protection Agency (EPA) regulates the general public's exposure to asbestos in buildings, drinking water, and the environment. Because the asbestos cancer is so fast growing, it is often not diagnosed until the later stages of the disease, when the chance of patient survival is poor. Under the Regulations, two licences have been established—Class A and Class B. Businesses with a Class A licence are permitted to remove all types of asbestos, including both friable and non-friable asbestos.
