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.
The 2008 Bernie Banton Law — named for a deceased mesothelioma sufferer who tirelessly campaigned for new legislation — allows citizens of Victoria to seek compensation if diagnosed with asbestosis, a progressive lung disease caused by exposure to asbestos fibers. Some asbestos claims may depend on such things as dates of exposure to asbestos and some schemes also support medical surveillance of asbestos-exposed workers.
ASEA also provides an Asbestos Exposure Register, where people who may have been exposed to asbestos can register the details of their exposure. The results of the monitoring program demonstrated the airborne asbestos fibre concentrations in proximity to the former asbestos factory site in Gaythorne are consistent with low asbestos fibre concentrations found in other areas of Brisbane. The amount of asbestos used as we speak has dramatically decreased as a result of government warnings and limitations of usage. Stable asbestos compounds, such as intact cement, tiles, or other products are generally not an immediate hazard.
Vitamin E and C, beta-carotene, selenium, and the B vitamins have also been associated with a decreased risk of lung cancer. The use of asbestos in new construction projects has been banned for health and safety reasons in many developed countries or regions, including the European Union, Australia, Hong Kong, Japan, and New Zealand. Asbestos has been used in a wide number of products due to its flexibility, tensile strength, insulation, chemical inertness and affordability. The effects of asbestos on NF-B and TNF activation were inhibited by oxygen radical scavengers and were enhanced by antioxidant enzyme inhibitors.
