Asbestos is classified as a group I carcinogen by the World Health Organization, its fibers are small and not visible to the naked eye, and can be easily inhaled into the lower respiratory tract, causing diseases such as asbestosis, lung cancer, pleural mesothelial bovine tumors, etc. Asbestos-related diseases tend to have a long incubation period, which may not appear until 10-40 years later.
Asbestos is used in residential and office buildings, schools and hospitals, household consumer goods, electrical and electronic products, automobiles and automotive brake pads and clutch pads, lubricants and pharmaceutical packaging. It can be said that almost every industry from aviation, aerospace, construction, petroleum, textiles, etc. uses asbestos, and is even used in cheese and wine brewing equipment, asbestos is often mixed in powder form in its products, asbestos is not harmful in normal conditions, and it is absolutely safe to use it in construction without destroying it. However, once destroyed, countless extremely fine fibers like steel wires will be suspended in the air for a long time.
One gram of asbestos contains about 1 million fibers, and the diameter of asbestos is generally 05 microns, and the average diameter of the hair is 60 to 90 microns, so with the naked eye is simply invisible, so many people do not take it seriously. When inhaled, it is like a steel needle pierced into the lungs, never metabolized, and the lungs will form scar tissue to gradually wrap around these fibers, and the scar tissue will hinder the normal function of the lungs themselves, which means that the lungs will gradually be unable to inhale enough air.
Asbestos is widely used in housing construction, and do-it-yourself home renovation can lead to the release of asbestos.
ABC TV reported in 2012 that a young man died of lung cancer in his early 20s when he was just able to walk because his parents renovated his house and caused him to inhale asbestos.
Asbestos may be present in automotive components, including but not limited to asbestos brake pads, clutches, exhaust pipe gaskets. In 2012, 20,000 Chinese-made cars were recalled in Australia because 17 of these cars' engine cylinder gasket sets, exhaust pipe gaskets, throttle valves, engine intake pipes, and exhaust pipes contained asbestos materials.
The forthcoming GB30512-202X (Requirements for Prohibited Substances in Road Vehicles) clearly stipulates that automobiles, trailers, motorcycles and their parts and components are a single homogeneous material (non-metallic material).Must not be detectedAsbestos, Shanghai Murui reminds that enterprises involved in all parts should respond to regulatory requirements in advance to avoid unnecessary losses to enterprises.
